Whales have what seem like remnants of a pelvis and femur, as shown here. What are these structures an example of?

Answers

Answer 1

Answer: vestigial limbs

vestigial limbs are the remnants from the development of any one organism's ancestors.

Humans, for one example, have no real need for an appendix now that we are no longer herbivores.

Look at a x-ray image of certain snakes and you can see the structural remains of feet.

Answer 2

Answer:

In short, the answer Vestigial structures.

Good luck!

Celiac disease causes the destruction of the villi cells. Which of the following is most likely to happen to people with celiac disease

Answers

They lose the ability to gain nutrients.

Hence, people with celiac disease cannot tolerate gluten. Gluten is a type of protein found as nutrient in food and is released to the digestive system. When the body receives food that contains gluten (e.g. wheat, rye, and barley) the immune systems responds and attacks the small intestines. In the event of this, the linings of the small intestine called villi are damaged. When the villi get damaged, the body cannot properly absorb nutrients.

What do mutation, genetic recombination, and gene flow add to a population?genetic uniformity
evolution
genetic variation
natural selection

Answers

Genetic variation is brought about by mutation, genetic recombination, and gene flow in a population. Therefore, option (C) is correct.

What is genetic variation?

The differences in DNA sequences that exist between individuals within the same group are referred to as genetic variation. Both germ cells, which include sperm and eggs, and somatic cells, which include all other types of cells, are subject to variation.

One source of genetic variation is mutations, which can be defined as any alteration in the sequence of genes found in DNA. Gene flow, which can be defined as the movement of genes across various groups of organisms, is still another source. The final cause of genetic diversity is sexual reproduction, which results in the formation of new gene combinations and can be a consequence of sexual reproduction.

An apple appears red because it red wavelengths.

Answers

Answer:

Reflects the red light

Explanation:

The optical physics says that whatever color we perceive for any object is the color of the light of any particular wavelength that is reflected by the object instead of observing. Rest all form of light waves except the one which is reflected are absorbed or transmitted by the object. For instance – leaves appear green because they reflect the green light and this is the reason that when plants are exposed to green light they are not able to photosynthesize.

A 'red' apple does not emit red light. Rather, it simply absorbs all the frequencies of visible light shining on it EXCEPT for a group of frequencies that is perceived as red, which are REFLECTED. An apple looks red to us because it REFLECTS infrared waves.

Which best describe fetus development?

Answers

NOT a characteristic of a behavior.a. It can be observed.
b. It can be recorded.
c. It can be influenced by the environment.
d. It can include a person’s thoughts.

Answers

NOT a characteristic of a behavior is that it can be influenced by the environment. The answer to your question is C. I hope this is the answer that you are looking for and it comes to your help.

Answer : The correct answer is-

c. It can be influenced by the environment.

Behaviour can be described as collection/set of actions/emotions that are performed/exhibited by particular organism. It describes the way in which organism responds to the conditions in his/her surroundings.

The behavioral characteristics can be observed (through actions) and recorded, and it includes the perception or thoughts of the individuals.

Thus, Option c) does not depict the characteristic of behavior.
