Answer:

Photosynthesis converts carbon dioxide and water into oxygen and glucose. Glucose is used as food by the plant and oxygen is a by-product. Cellular respiration converts oxygen and glucose into water and carbon dioxide. Water and carbon dioxide are by- products and ATP is energy that is transformed from the process.

I hope that helps determine your answer.

The product of photosynthesis are the reactants of cellular respiration.

Cellular respiration is the process by which cells convert the energy stored in food molecules into a form of energy that can be used by the cells.

This process takes place in the mitochondria of the cell and involves the oxidation of glucose (sugar) to produce ATP (adenosine triphosphate), which is the main energy source for cellular processes. Cellular respiration has several stages, including glycolysis, the citric acid cycle, and the electron transport chain, each of which contributes to the generation of ATP. The end product of cellular respiration is carbon dioxide and water.

Explanation:

Out of all of the answer choices, answer C most properly describes the cell cycle.

When treated with pepsin, the oligopeptide ALKMPEYISTDQSNWHHR would yield two peptide fragments. Cleavage occurs between the phenylalanine (F) and leucine (L) residues, resulting in fragments ALKMPEYISTDQSNW and HHR.

Pepsin specifically cleaves peptide bonds following aromatic amino acids (phenylalanine, tryptophan, and tyrosine) and certain amino acids like leucine, methionine, and glutamic acid. Analyzing the given oligopeptide, we can identify potential cleavage sites. Pepsin would cleave after the phenylalanine (F) residue, resulting in two fragments: ALKMPEYISTDQSNWHHR.

Therefore, the answer is "2" peptide fragments. The cleavage takes place between the phenylalanine (F) and the following leucine (L) residues. This would yield two separate peptide fragments: ALKMPEYISTDQSNW and HHR. The first fragment ends with the last amino acid cleaved, while the second fragment starts from the cleavage site and continues until the end of the oligopeptide.

The levels of cdks (cyclin-dependent kinases) remain constant over the cell cycle, but their activity rises and falls due in part to cyclic changes in the levels of cyclins.

Cyclins are proteins that regulate the activity of cdks. They are named cyclins because their levels cyclically rise and fall throughout the cell cycle. Different cyclins are present at different stages of the cell cycle, and each cyclin is specific to certain cdks.
When a specific cyclin binds to its corresponding cdk, it activates the cdk, leading to the phosphorylation of target proteins and progression of the cell cycle. Once the cyclin has fulfilled its function, it is degraded, and its levels decrease until the next stage of the cell cycle when a different cyclin takes over.
For example, the G1 cyclin binds to a cdk at the G1 phase of the cell cycle, promoting the transition from G1 to S phase. Then, the G1 cyclin is degraded, and the S cyclin takes its place to activate cdks required for DNA replication in the S phase.

In summary, the levels of cdks remain constant, but their activity is regulated by cyclic changes in the levels of cyclins throughout the cell cycle.

Males fighting to show off for females to get the female to choose them is an example of intersexual selection. Intersexual selection, also known as mate choice, refers to the selection of a mate based on traits that are attractive to the opposite sex. In contrast, intrasexual selection refers to competition between members of the same sex for access to mates. In many species, males compete with one another for access to females, and the most successful males are often those that are the strongest, most aggressive, or have the most elaborate displays. This type of competition can lead to the evolution of exaggerated traits that are used primarily for competition, such as antlers in deer or elaborate plumage in birds.

They use different technological devices to measure caves at the Yucatan Peninsula.

Explanation:

Background Reading:

Human presence on the Yucatán Peninsula reaches back to the Late Pleistocene. Osteological evidence comes from submerged caves and sinkholes (cenotes) near Tulum in the Mexican state of Quintana Roo. Here we report on a new skeleton discovered by us in the Chan Hol underwater cave, dating to a minimum age of 9.9±0.1 ky BP based on 230Th/U-dating of flowstone overlying and encrusting human phalanges. This is the third Paleoindian human skeleton with mesocephalic cranial characteristics documented by us in the cave, of which a male individual named Chan Hol 2 described recently is one of the oldest human skeletons found on the American continent. The new discovery emphasizes the importance of the Chan Hol cave and other systems in the Tulum area for understanding the early peopling of the Americas. The new individual, here named Chan Hol 3, is a woman of about 30 years of age with three cranial traumas. There is also evidence for a possible trepanomal bacterial disease that caused severe alteration of the posterior parietal and occipital bones of the cranium. This is the first time that the presence of such disease is reported in a Paleoindian skeleton in the Americas. All ten early skeletons found so far in the submerged caves from the Yucatán Peninsula have mesocephalic cranial morphology, different to the dolicocephalic morphology for Paleoindians from Central Mexico with equivalent dates. This supports the presence of two morphologically different Paleoindian populations for Mexico, coexisting in different geographical areas during the Late Pleistocene-Early Holocene.

Explanation:

During the day, green plants carry out photosynthesis. Plants also breathe during the day. Respiration is the process of oxidizing glucose to release energy for cellular activity and enable plants to survive.

Therefore, plants need to breathe in order to obtain energy to carry out their cellular activities. Photosynthesis But when plants say they take in oxygen, they don't actually need to take in oxygen during the day. This is because plants produce more oxygen than they need for respiration during photosynthesis during the day. This is also why plants can release oxygen during the day. Some of the oxygen produced by photosynthesis is used by the plants themselves, while the rest is released into the atmosphere.

Explanation:

The population after 40 years will be 400,000 animals, and the population after 65 years will be approximately 336,000 animals.

To determine the population after a certain time period, we can use the formula for exponential decay;

N(t) = N0 × \((1/2)^{(t/T)}\)

Where;

N(t) is the population at time t

N0 is the initial population

t is the time elapsed

T is the half-life of the population

Given;

N0 = 1.6 million

T = 20 years

Let's calculate the population after 40 years;

N(40) = 1.6 million × \(1/2^{(65/20)}\)

= 1.6 million × (1/2)²

= 1.6 million × (1/4)

= 400,000

Therefore, the population after 40 years will be 400,000 animals.

Now, let's calculate the population after 65 years;

N(65) = 1.6 million × \((1/2)^{(65/20)}\)

= 1.6 million × \((1/2)^{(13/4)}\)

≈ 1.6 million × 0.210

≈ 336,000

Therefore, the population after 65 years will be approximately 336,000 animals.

As the skateboarder moves, several energy transformations take place within their body. Some of the energy transformations include:

1. Chemical energy to kinetic energy: When the skateboarder pushes off the ground, the energy stored in the chemical bonds of their muscles is converted into kinetic energy, which is responsible for their motion.

2. Kinetic energy to gravitational potential energy: As the skateboarder moves up a ramp, their kinetic energy is converted into gravitational potential energy.

3. Gravitational potential energy to kinetic energy: When the skateboarder moves down the ramp, the gravitational potential energy is converted back into kinetic energy.

4. Kinetic energy to thermal energy: As the skateboarder moves, they also experience frictional forces which convert some of their kinetic energy into thermal energy.

5. Chemical energy to thermal energy: The continuous movement of the skateboarder requires the energy stored in their muscles to be converted into thermal energy, which is released as heat.

I hope that the assistance I provided was helpful.

The motion of the skateboarder is powered by energy transformations that occur within their body. As the skateboarder moves, their body converts stored chemical energy (from food) into kinetic energy, which is the energy of motion. This conversion happens through a series of complex biochemical processes that occur within the skateboarder's muscles.

When the skateboarder pushes off the ground, their leg muscles contract, converting chemical energy stored in the form of ATP (adenosine triphosphate) into kinetic energy as the legs move and the skateboarder accelerates. As the skateboarder continues to move, the muscles in their body work together to maintain balance and control, converting chemical energy into kinetic energy and potential energy as the skateboarder jumps, turns, and performs tricks.

Additionally, the skateboarder's body also experiences other forms of energy transformation during this process. For example, as the skateboarder moves, their body generates heat through metabolic processes, which is a form of thermal energy. The skateboarder also loses energy through friction with the ground and air resistance, which is converted into heat and sound energy.

In summary, the motion of the skateboarder is powered by a series of complex energy transformations that occur within their body. These transformations involve the conversion of stored chemical energy into kinetic and potential energy, as well as the generation of heat and sound energy through friction and air resistance.

Explanation:

beats me i'm just trying to help

the answer to this is you have to show how sound waves get propagated from the cymbal to the ear.

when cymbal is hit(doesn't matter the force used to hit it) the energy dissipates and creates circular waves just like when a stone hits a pond.

A. I recommend drawing the cymbal dissipating circular wave from the energy of the hit.

B. as the circular wave propagates it creates compression and rarefactions. as sound wave reaches the air it displaces the air particle and if it happens to to several nearby air particles it creates compressions( lines that look like ||||) where there's high pressure a typical restoring force will cause the particle to move back to their original positiin creating low pressure region(| | |).

I think that's what you should draw.

C. when sound is received it comes with the compressions and rarefactions (||||| | | | ||||) which are high pressure and low pressure respectively. As high pressure reaches the eardrum it pushes it inwards and as the low pressure comes it pushes the eardrum outwards causing it to vibrate setting a vibrational motion. since the eardrum is attached to the bones of the middle ear, as the bones begin to vibrate then the sound wave-pressure wave-mechanical vibrations in the bones.

the vibrations are then transmitted to the fluid in the inner ear where they are converted to electric impulses and transmitted to the brain to be interpreted.

if the sound waves come more frequently then the eardrum vibrates more frequently and it can be interpreted as high pitch sound and if the intensity of the sound wave is high it is characterized by air particles with high amplitude and produce a forceful vibration in the eardrum and the brain will perceive it to be a high sound.

Cell is found to have twice as much DNA as the diploid state but is not in the process of replicating the DNA. All of  DNA is found within a single nucleus then the phase of the cell cycle is G2 phase.

Period of rapid cell growth and protein synthesis when the cell prepares itself for mitosis is called G2 phase. During G 2​, the cell grows more, makes proteins and organelles . And then begins to reorganize its contents to prepare for mitosis.

After DNA replication is completed in S phase then the cell enters G2 phase and has twice the amount of the DNA of the starting cell. This is later followed by mitosis and cell division which leads to the formation of two diploid daughter cells.

Process by which double-stranded DNA molecule is copied to produce two identical DNA molecules is called DNA replication. Replication is important process because whenever a cell divides then two new daughter cells must have the same genetic information.
