How homologous structures and vestigial structures are evidence of evolutionary relationships.

Biology
1 answer:
natali 33 [55]3 years ago
3 0

Answer:

Due to presence of these structures in ancient as well as modern organisms.

Explanation:

Homologous and vestigial structures are the evidences that show  evolutionary relationships between organisms because these structure were also present in the ancient ancestor of that organism. These homologous and vestigial structures shows the relationship between the ancient and the modern organisms. Some structure has a purpose and function in the body of ancient organisms but with the passage of time those structure are useless and have no function in the body but these structure shows connection between modern and ancient organisms.

What are all of the energy transformations that take place as sunlight is converted to usable energy within humans
Charra [1.4K]
<span>The energy transformation in the sun is primarily the change of nuclear energy to light energy. 

More Explainable: </span><span>The sun is said to "burn hydrogen" but what that really means is that near the center of the sun there is enough temperature and pressure to cause the fusion of hydrogen nuclei (protons) into helium nuclei (two protons and two neutrons). The fusion (not fission) reaction energy give off energy in a complex way that includes heat and light. The light works its way out from the center of the sun to the surface and eventually out of the surface into space. That is the sunlight we see as well as some light that is outside our range of vision. The light is electromagnetic energy. </span>

Which of the following is an example of maintaining homeostasis? Learning Jumping Shivering Smiling
Anestetic [448]
The answer is D, sweating.

Homeostasis is where the body uses some mechanisms to maintain a optimum condition for the body to function. These conditions may include body temperature, blood glucose level etc.

Sweating is a mechanism that can help maintain the body temperature. During hot conditions, the sweat glands under the skin surface may produce sweat, which is then released to the skin surface. When the sweat is on the skin surface, they evaporate. During evaporation, heat energy is brought away from the skin as the sweat molecules that have a higher kinetic energy (=temperature) escaped from the sweat drop. The average temperature of the sweat is reduced. Eventually, the temperature of the body is decreased and this help maintain the suitable temperature for the body to function.

Therefore, your answer is D, sweating.

In the citric acid cycle when an aldol addition occurs in a biological system, how do the amino acids contained in the Citrate S
kotegsom [21]

Answer:

Citrate Synthase facilitates the formation of citrate by deprotonating Acetyl CoA and by protonating the carbonyl oxygen of oxaloacetate

Explanation:

Citrate synthase is a key enzyme in the citric acid cycle that functions to catalyze the formation of citrate from oxaloacetate and acetyl-CoA: acetyl-CoA + oxaloacetate + H2O >> citrate + CoA-SH (Coenzyme A ). This enzyme contains three amino acids at its active site that work together to catalyze the conversion of acetyl-CoA and oxaloacetate into citrate. This active site acts by abstracting (deprotonating) a proton from the alpha carbon of Acetyl CoA which serves as the nucleophile. Subsequently, the active site of the enzyme also protonates the carbonyl oxygen of oxaloacetate, which then suffers nucleophilic attack and thereby facilitating nucleophilic substitution reaction.
