cellular respiration how cells harvest energy
Answers
Answer:
Cellular Respiration: a process able to extract a large amount of energy from food molecules. In eukaryotic cells oxygen is a required component. This metabolic process is the main reason that animals have elaborate gas exchange organs such as lungs, gills and other systems. The goal of these systems is, of course, to get access to oxygen and to get rid of carbon dioxide.

D. The survivors were likely from the black areas of the map but adapted to the difference in temperature in the laboratory.
Answers
The survivors were likely collected from the light gray areas on the map those from other regions could not adapt. That is option B
The effect of temperature change on organismsThere are some organisms such as plants and animals that are capable of changing and adjusting to different environmental conditions.
Aquatic animals such as jellyfish can adapt to warmer ocean waters, but not necessarily to extreme heat or extreme cold weather. That is, it can survive the temperature of 12 - 24°C as indicated in the figure.
But some species of jellyfish that has adapted in extreme cold and extreme hot weather, may find it difficult to abruptly adapt to an average weather.
Therefore when placed in the 20°C aquarium, they couldn't survive because of the temperature of the new environment.

The repeating sequence of events in eukaryotes that involves cell growth and cell division is called the . (one word per blank)
Answers
Answer:cell cycle
Explanation:
The repeating sequence of events in eukaryotes that involves cell growth and cell division is called as cell cycle.
What is cell cycle?
A cell cycle is a series of events that takes place in a cell as it grows and divides. A cell spends most of its time in what is called interphase, and during this time it grows, replicates its chromosomes, and prepares for cell division. The cell then leaves interphase, undergoes mitosis, and completes its division.
The cell cycle is a four-stage process in which the cell increases in size (gap 1, or G1, stage), copies its DNA (synthesis, or S, stage), prepares to divide (gap 2, or G2, stage), and divides (mitosis, or M, stage).
The cell cycle can be thought of as the life cycle of a cell. In other words, it is the series of growth and development steps a cell undergoes between its “birth”—formation by the division of a mother cell—and reproduction—division to make two new daughter cells.

Answers
When the signal is not present, the phosphorylation cascade is inactive. This means that the second protein, tf2, remains in the nucleus, while the other proteins, p1, p2, p3, and p4, are all inactive.
Protein p1 is the only protein which is active, but since there is no signal, it does not activate any of the other proteins. With no signal, the phosphorylation cascade does not proceed, and thus the proteins remain inactive and the signal is not transduced.
As a result, the targeted response of the cell does not occur. This illustrates the importance of a signal for the phosphorylation cascade to occur, as without it, the response of the cell does not proceed.

Create an argument to support the claim made in the readings that jade plants have properties that allow them to survive long dry spells. Cite reasons and evidence from the texts to support the claim. Also cite what you may already know about succulents to support the claim
Answers
The claim made in the readings that jade plants have properties that allow them to survive long dry spells can be supported by several reasons and evidence from the texts.
Firstly, jade plants belong to the succulent family. Succulents are a group of plants that have adapted to survive in arid environments with little water availability. They store water in their leaves, stems, or roots, allowing them to withstand long periods without rainfall. This ability to store water is a key adaptation that enables succulents, including jade plants, to survive in dry spells.
Additionally, the text may provide evidence of specific characteristics of jade plants that contribute to their ability to survive in drought conditions. For example, the text may mention that jade plants have thick, fleshy leaves that can store water. These leaves have a waxy coating that helps reduce water loss through evaporation. This adaptation allows jade plants to retain moisture for extended periods, even in dry conditions.
Furthermore, jade plants often have shallow root systems that spread out horizontally rather than deeply into the soil. This helps them capture any available rainfall quickly and efficiently. The shallow roots also allow them to absorb moisture from the air when it is present, further supporting their survival during dry spells.
Considering what we may already know about succulents, we can further support the claim. Succulents, including jade plants, have evolved to survive in harsh, arid environments where water is scarce. Their ability to store water in their tissues and their efficient water-use strategies make them well-equipped to withstand prolonged dry spells.
In summary, jade plants possess several characteristics that allow them to survive long dry spells. These include their succulent nature, which enables water storage in their leaves, stems, or roots, as well as their ability to reduce water loss through waxy leaf coatings. Their shallow root systems and efficient water-use strategies also contribute to their survival during drought conditions.

Below is a polyacrylamide gel showing whether or not Cas9 can cut. In the experiment on the left, the strand of DNA that is complementary to the crRNA is labeled. In the experiment on the right, the strand of DNA that is noncomplementary to the crRNA is labeled. The authors made mutations in each of the nuclease domains of Cas9. c. (2 points) Are the.complementary and noncomplementary strands cut in the same manner? Remember that polyacrylamide gels have single nucleotide resolution (in the Sanger sequencing slides). d. (2 points) Do these domains act independently of each other or is the activity of one nuclease domain required for the activity of the other nuclease domain?
Answers
In the polyacrylamide gel shown in the experiment, we can observe whether or not Cas9 can cut both the complementary and noncomplementary strands of DNA. In the experiment on the left, the complementary strand of DNA is labeled, while in the experiment on the right, the noncomplementary strand of DNA is labeled.
To answer the first question, we need to compare the bands observed in both experiments. If we see that both the complementary and noncomplementary strands are cut in the same manner, we can conclude that Cas9 cuts both strands in a similar fashion. However, if we see that the bands in both experiments are different, we can infer that Cas9 cuts the two strands differently.
Regarding the second question, we need to determine whether the nuclease domains of Cas9 act independently of each other or if the activity of one nuclease domain is required for the activity of the other nuclease domain. To answer this question, we need to analyze the mutations made in each of the nuclease domains of Cas9 and see if they affect the activity of the other domain.

c. Lead times, supply chain
Answers
The inventory inputs to MRP include lead times, safety stocks, and product structure trees.
Material Requirement Planning (MRP) is a system that is utilized for scheduling, planning, and controlling production processes. MRP assists businesses in maintaining ideal inventory levels, scheduling deliveries, and ensuring the efficient use of resources. It relies on various inventory inputs to function, and some of these inputs include lead times, safety stocks, and product structure trees.
Lead time refers to the time taken from the order of the material to the delivery of the material. This means the lead time involves the ordering, waiting, and delivery times. In MRP, lead times are important inputs since they enable the system to calculate the required materials, quantities, and timing needed to meet the production requirements.
Safety stocks are the extra stocks kept by a company to safeguard against unexpected situations like a surge in demand or unexpected delivery delays. In MRP, safety stocks are important inventory inputs since they help the system determine the ideal amount of inventory that the company should have on hand.
Product structure trees, also known as bills of materials, are documents that contain information on the components required for manufacturing a product. In MRP, product structure trees are important inventory inputs since they enable the system to calculate the quantities of raw materials required for production.

suppose you had to subsist on a diet of whale blubber and seal blubber, with little or no carbohydrates. what would be the effect of carbohydrate deprivation on the utilization of fats for energy?
Answers
To begin with, carbohydrates are the main source of energy for our bodies, but in the absence of carbohydrates, our body will start to rely on fats for energy. When you subsist on a diet of whale blubber and seal blubber with little or no carbohydrates, your body will undergo a state of ketosis, where the liver will start to produce ketones from fats for energy.
This process will increase the utilization of fats for energy and reduce the dependency on carbohydrates. However, carbohydrate deprivation may also lead to fatigue, weakness, and brain fog due to the lack of glucose, which is the preferred source of energy for the brain. Additionally, a diet high in animal fats can lead to other health problems such as cardiovascular disease and high cholesterol levels. In conclusion, while the utilization of fats for energy may increase in the absence of carbohydrates, it is important to maintain a balanced and healthy diet to avoid potential health risks.

secretion of atrial natriuretic
A> peptide decreases E. potassium excretion. B. decreases sodium excretion.
C. increases sodium excretion.
D. increases potassium excretion.
Answers
Secretion of atrial natriuretic (C) increases sodium excretion.
Atrial natriuretic peptide (ANP) is a hormone released by the atria of the heart in response to increased blood volume and pressure. One of its primary functions is to regulate fluid and electrolyte balance in the body.
ANP acts on the kidneys to increase sodium excretion, which leads to increased urine production and a decrease in blood volume. This helps to reduce blood pressure.
While ANP primarily affects sodium excretion, it does not have a direct effect on potassium excretion. Therefore, option A (decreases potassium excretion) and option D (increases potassium excretion) are not correct. Option B (decreases sodium excretion) is also incorrect as ANP actually increases sodium excretion. The correct answer is C, which states that ANP increases sodium excretion.

if glucagon binds to surface receptors on liver cells to send an intracellular message for glycogen breakdown, this process is known as which mechanism of action?
Answers
The process described, where glucagon binds to surface receptors on liver cells to initiate intracellular signaling for glycogen breakdown, is known as the second messenger mechanism of action.
The second messenger mechanism of action is a common signaling pathway utilized by various hormones and neurotransmitters. It involves the activation of cell surface receptors, such as G protein-coupled receptors (GPCRs), by the binding of a ligand (in this case, glucagon). Once the ligand binds to the receptor on the cell surface, it triggers a series of intracellular events that ultimately lead to a cellular response.
In the case of glucagon signaling in liver cells, upon binding to the receptor, the GPCR undergoes conformational changes and activates intracellular G proteins. These G proteins then trigger the production or release of second messengers, such as cyclic AMP (cAMP), which serve as signaling molecules within the cell. The second messengers propagate the signal and activate downstream signaling pathways, ultimately resulting in glycogen breakdown in the liver.
Therefore, the mechanism of action described, where glucagon binds to surface receptors on liver cells to initiate intracellular signaling for glycogen breakdown, is known as the second messenger mechanism of action.

Describe what happens to carbohydrates in the human body between ingestion and assimilation in the liver.
Answers
Carbohydrates are broken down into glucose, absorbed by the small intestine, transported to the liver, and used for energy or stored as glycogen or fat depending on the body's needs.
Insulin is a hormone produced by the pancreas that regulates the amount of glucose in the bloodstream. If there is a high amount of glucose in the bloodstream, insulin will signal to the liver and muscle cells to absorb and store the excess glucose. If there is a low amount of glucose in the bloodstream, glucagon will signal the liver to break down the stored glycogen into glucose and release it into the bloodstream to be used for energy.
When carbohydrates are ingested, they are digested in the mouth and stomach. The carbohydrates are broken down into glucose. The glucose is absorbed by the small intestine. The glucose is then transported to the liver.
The glucose is used for energy and stored as glycogen in the liver and muscles for later use. If there is an excess of glucose, it will be stored as fat in the adipose tissue.

After nervous stimulation stops, calcium ions returning to the sarcoplasmic reticulum prevent ACh in the synaptic cleft from continuing to stimulate contraction True False
Answers
Answer:
False.
Explanation:
Neurotransmitter release occurs from the nervous terminal or varicosities in the neuronal axon. When an action potential reaches the nervous terminal, the neurotransmitter is released by exocytose. The molecule binds to its receptor in the postsynaptic neuron, triggering an answer. As long as the signal molecule is in the synaptic space, it keeps linking to its receptor and causing a postsynaptic response. To stop this process the neurotransmitter must be taken out from the synaptic space. There are two mechanisms by which the neurotransmitter can be eliminated:
• Enzymatic degradation/deactivation: There are specific enzymes in the synaptic space, which are in charge of inactivating the neurotransmitter by breaking or degrading it. The enzyme acetylcholinesterase prevents ACh from continuing to stimulate contraction.
• Reuptake: Receptors located in the presynaptic membrane can capture de molecule to store it back in new vesicles for posterior use. These transporters are active transport proteins that easily recognize the neurotransmitter.
