Evidence of Evolution in the human body?

Biology
1 answer:
expeople1 [14]2 years ago
4 0

Answer:

Another type of evidence for evolution is the presence of structures in organisms that share the same basic form. For example, the bones in the appendages of a human, dog, bird, and whale all share the same overall construction ([Figure 2]). That similarity results from their origin in the appendages of a common ancestor.

Explanation:

Hope it helps :)

A student conducts an experiment. He mixes two chemicals in a beaker at 30 ° Celsius. Then, he repeats the experiment at 45 ° Ce
Salsk061 [2.6K]

The most likely conclusion the student will make would be that increasing temperature increases the rate of reaction.

<h3>Effects of temperature on reaction rates</h3>

The rate of reaction of a system is directly proportional to the temperature of the system.

This is because the kinetic energy of the reactant's molecules is increased by increasing the temperature of the system. Thus, reactant molecules collide more and this leads to more reactions.

Thus, increasing the temperature of a system moderately also increases the rate of reaction in the system. Too much increase in temperature, however, can destroy the structures of reactants.

Which of the following statements about oxidative phosphorylation by ATP synthase is FALSE? A) The electrochemical gradient acro
Alina [70]

Answer

D)A proton gradient alone without a corresponding energy input is not sufficient to drive the synthesis of ATP

Explanation:

Oxidative phosphorylation reffers to metabolic pathway whereby enzyme is used by the cell to achieve nutrient oxidation, so that chemical energy of molecular oxygen is released as a result of this, adenosine triphosphate (ATP) is manufactured. oxidative phosphorylation is seen in all organisms that are aerobic in nature and it occur in the mitochondria of all eukaryotic organisms. There is electron transfer during oxidative phosphorylation, the electrons moves from the donor to the receptor and this is known as redox reaction, as a result of this energy is released, and this energy is used for formation of ATP.

Therefore,among all the options, A proton gradient alone without a corresponding energy input is not sufficient to drive the synthesis of ATP is the false statement.

If you eat a lot of food, will you gain weight? Explain why or why not.
natka813 [3]
The accurate answer to this is: it depends.

The type of food a person eats can affect him or her differently than another type of food. An additional factor is how active the person is.

For example, if a person does not exercise and eats McDonalds constantly, he/she is more susceptible to weight gain than a person who exercises often and eats healthy foods.In addition, the amount of calories a person eats and burns has an affect on the person's weight gain.

I hope this answers your question!
