the left ventricle a. is decreased in size by endurance training. b. has the thinnest wall of the cardiac chambers. c. is increased in size with strength training. d. pumps blood into the peripheral circulation against the low blood pressure.

Answers

Answer 1

Through a bigger blood volume and a stronger contraction of the ventricles, which results in the ejection of more blood every beat, endurance exercise enhances cardiac output. Blood volume increases as a result of the increased oxygen demand. In people with Fontan-type circulation, resistance muscle training increases muscle mass and strength and is linked to improvements in the ventricular filling, stroke volume, exercise capacity, and cardiac output on CPAP.

A slower consumption of muscle glycogen and blood glucose, a larger dependence on fat oxidation, and reduced lactate generation during the exercise of a given intensity are the main metabolic effects of muscle adaptations to endurance exercise. By causing the ventricles to contract more forcefully and pump out more blood per beat, endurance training raises the cardiac output. An increase in blood volume is also prompted by the rise in oxygen demand. Resistance muscle training increases muscle mass and strength in people with Fontan-type circulation and is linked to increased ventricular filling, stroke volume, exercise capacity, and cardiac output on CPAP.

In this food chain, plankton are the primary producers, which means they convert energy from the sun into organic matter through photosynthesis. The other organisms are consumers, which means they obtain energy by consuming other organisms.

- Plankton (primary producer)

- Moral eel (primary consumer)

- Shark (secondary consumer)

- Orca (tertiary consumer)

The transfer of energy in this food chain can be described as follows:

- Plankton produce organic matter through photosynthesis, converting solar energy into chemical energy.

- Moral eels consume plankton, obtaining the energy stored in their organic matter.

- Sharks consume moral eels, obtaining the energy stored in their organic matter.

- Orcas consume sharks, obtaining the energy stored in their organic matter.

At each level, some energy is lost through metabolic processes such as respiration and digestion, and only a portion of the energy stored in the organic matter is transferred to the next level. This is known as the 10% rule, which states that only 10% of the energy from one level is transferred to the next level.

What is osmosis?

Osmosis is the simple passive transport of water molecules that occurs when two dilutions of different concentrations are separated by a semipermeable membrane.

The membrane allows the pass of water but not solute. Hence, water can move from the most diluted side (higher water potential) to the less diluted one (lower water potential).

Let us remember that the water potential is the potential energy in a mass of water. Among other factors, it depends on solute concentration,

Most diluted side ⇒ higher water potentialMost concentrated side ⇒ lower water potential

Concerning solute concentrations,

the hypertonic solution is the one with the highest solute concentrationthe hypotonic solution is the one with less solute concentration. The most diluted one. isotonic solutions are those with equal solute concentrations.

1. What is the % of glucose outside the cell? 10%

2. What is the % of water outside the cell? 90%

3. What is the % of water inside the cell? 80%

4. Will osmosis occur? Yes, because there is a difference in solute and water concentration.

5. If so, which way will water move (into or out of the cell)? Into the cell.

6. Will the cell swell or shrink? the cell will swell because water in goin in.

Split-brain patients can search for and identify a visual target item in an array of similar items _____________ than healthy controls can—presumably because _______________________

Answers

Split-brain patients can search for and identify a visual target item in an array of similar items faster than healthy controls can—presumably because their divided brain hemispheres allow for parallel processing and independent visual search capabilities.

Split-brain patients are individuals who have undergone a surgical procedure called corpus callosotomy, which involves severing the corpus callosum, the main connection between the brain's left and right hemispheres. This procedure is usually performed to alleviate severe epilepsy.

When split-brain patients are presented with an array of visual stimuli and asked to search for a specific target item, they often demonstrate faster search times compared to healthy individuals. This phenomenon is attributed to the independent processing capabilities of their divided brain hemispheres.

In split-brain patients, visual information presented to one hemisphere remains isolated within that hemisphere, without direct communication with the other hemisphere. As a result, each hemisphere can simultaneously process visual stimuli in parallel and independently conduct a visual search for the target item.

Which one of the statements about translation in eukaryotes is correct?
A. An initiation complex recognizes a 5' cap structure and scans for the first AUG triplet.
B. Translation continues until the ribosome comes to the end of mRNA.
C. A single mRNA can possess multiple protein coding regions.
D. There is an untranslated region only at the 3' end of mature mRNA.
E. All of these choices are correct.

Answers

E. All of these choices are correct. Translation in eukaryotes starts with the recognition of a 5' cap structure and an AUG triplet by an initiation complex. This complex then initiates translation, which continues until the ribosome comes to the end of mRNA. A single mRNA can also possess multiple protein coding regions, and there is an untranslated region only at the 3' end of mature mRNA.

To explain further, the 5’ cap structure is a modified guanosine nucleotide attached to the 5' end of pre-mRNA. The initiation complex recognizes this cap structure, and then scans for the first AUG triplet, which is the start codon that initiates the translation. The ribosome then continues to translate until it reaches the end of the mRNA, usually a stop codon, where it terminates the translation process. Furthermore, a single mRNA can possess multiple protein coding regions, allowing it to produce multiple proteins from one mRNA transcript. Finally, there is an untranslated region (UTR) at the 3' end of the mature mRNA, which does not code for proteins, but it can have regulatory functions.
In conclusion, all of the given statements about translation in eukaryotes are correct.

What is the likely advantage of growing a genetically modified variety of tomato that remains fresh over several days?

Post-harvest losses due to delayed transportation would be reduced.
Disease-causing pests may never be able to attack such a variety of tomato.
When consumed it would provide more nutrients than the regular variety.
When consumed it would improve the quality of life of people with genetic disorders.

Answers

The likely advantage of growing a genetically modified variety of tomato that remains fresh over several days is that post-harvest losses due to delayed transportation would be reduced.

This is because tomatoes are highly perishable, and their shelf life is relatively short. With a genetically modified variety of tomato that remains fresh for several days, farmers and retailers can transport them over long distances without the risk of spoilage, thereby reducing post-harvest losses. This can increase the availability and affordability of tomatoes, especially in areas with inadequate storage and transportation facilities.

Additionally, consumers would have access to fresher and more nutritious tomatoes, which could have positive health benefits. Furthermore, reducing post-harvest losses can lead to increased profitability for farmers and retailers, which can have positive economic impacts. Overall, a genetically modified variety of tomato that remains fresh over several days can have significant advantages for agriculture, nutrition, and the economy.

ENSO phenomenon causes significan climate global changes, affecting especially the Southern Hemisphere. In south Asia regions, such as Philippines, the weather becomes cooler, drier than normal.

-----------------------------------

The El Nino Southern Oscillation -ENSO- phenomenon produces due to a complex system of climatic oscillations between the ocean and the atmosphere.

This phenomenon causes significant perturbations in the usual pluvial regimens in the tropics. It provokes

dry seasons in areas where it usually rains rainy seasons in desertic regions.

ENSO phenomenon is dominant in the global climate system.

SOUTHERN HEMISPHERE

⇒ Under normal conditions

Pacific warm water and air masses move westward, making it possible for cold water to ascend in South America´s coasts, in a process known as upwelling. Upwelling occurs in South America, providing nutrients from the bottom to the animals, especially fishes -which favors fisheries activities-. Humidity goes straight to the west precipitating in Eastsouth Asia, Australia, and New Zealand, among other places.

⇒ Under El Niño conditions

A tropical and weak stream in the Pacific acquires strength while the opposite streams debilitate. This change impedes warm water go eastward, remaining on South America´s coasts. Upwelling does not occur on the South America coasts. In some regions, temperatures rise, and unusual precipitations occur in desertic or dry areas -Atacama desert-.Other affected areas are Eastsouth Asia, Australia, and New Zealand, where there are fewer precipitations and cooler temperatures. Rainfall drops below the average, affecting crops and livestock.

Among the affected areas in the Eastsouth Asia, we can mension the Philippines. Their economic activities are particularly affected during ENSO events.

ENSO also provokes changes in general extratropical circulation, contributing to some abnormal situations in the northern hemisphere weather during winter, including severe precipitations and cooler temperatures in the southeast USA, north of Mexico, Gulf of Mexico, Strait of Florida, and western Cuba.

which group of genes in drosophila embryos must be mutated if the result is elimination of a significantly sized, contiguous region of segmentation?

Answers

The group of genes in Drosophila embryos must be mutated if the result is the elimination of a significantly sized, contiguous region of segmentation is gap genes.

What are gap genes?

Gap genes are a group of genes that are expressed throughout the central region of the Drosophila embryo. Gap genes, along with other segmentation genes, are responsible for establishing the boundaries between segments in the developing Drosophila embryo. Gap genes are classified into three broad categories: anterior, middle, and posterior, based on their expression patterns.

Gap genes in Drosophila are required for correct patterning of the anterior-posterior axis of the embryo. Gap genes are necessary for defining the broad regions of segmentation, which are then subdivided into smaller regions by pair-rule genes. The proper patterning of the Drosophila embryo requires the activity of gap genes.

In contrast to maternal genes, which establish the anterior-posterior axis of the embryo, gap genes define large, contiguous regions of the developing embryo and are necessary for setting up the basic body plan.
