<span>C is the correct answer. A is not correct because we do not know if nose size and eyebrow size are sex linked traits - nothing in the question suggests this. Moreover, heredity is not just the passing of sex linked traits. Heredity also includes traits that are not sex linked. B is not correct because genes are not located inside ribosomes. Genes are located on DNA. DNA synthesis does not cause heredity. DNA synthesis is the replication of the DNA prior to cell division. D is not correct. C is the correct answer because genes are located on DNA that is contained in a chromosome. DNA contains information about proteins. The information is hereditary, or passed down, from parent to child.</span>
Answer: Experience 1 is the one that has the greatest reliability.
Explanation: Because of this potential variation, biological experiments need to have a large sample size and preferably be repeated several times. With more samples and repeating the experiment more often, the probability of arriving at a wrong conclusion due to random variation is diminished. As experience 1 has had several repetitions, it is the experience with a more reliable result.
Answer:
Reflexes
Explanation:
<em>The complete question is :</em>
<em>What mechanisms help infants survive before they have an opportunity to learn adaptive behavior?</em>
<em>a. Dynamic systems</em>
<em>b. Motor skills</em>
<em>c. Reflexes</em>
<em>d. Vision and hearing</em>
<em></em>
- A muscle reaction that takes place automatically in response to stimulation is termed as a reflex action.
- The reflexes that are present in infants which helps them to survive before they display adaptive behavior are termed as infant reflexes.
