Q1. The answer is <span>c. a mechanism of evolution.
</span>
Natural selection is the differences in survival and reproduction as the consequence of differences in phenotypes. According to Darwin's theory of evolution, natural selection is the only factor that affects a frequency of different variations and it is the only mechanism of evolution.
Q2. The answer is c. interactions between individuals.
Organisms interact with other organisms or abiotic factors in some system. The interaction <span>between individuals affects their regular distribution. For example, if two groups are in competition for resources, to maximize resource utilization, they will probably live in different areas or will defend territory. Also, some symbiotic organisms are expect to be distributed similarly.</span>
Answer:
30% Thymine
Explanation:
If 30% of Adenine is present, it would be reasonable to assume that 30% of Thymine will be present, as the ratio between the two complementary nitrogenous bases will be roughly equal.
Therefore, that leaves us with 40% between Cytosine and Guanine. Since the ratio between them would be equal, it gives us 20% of Cytosine and 20% of Guanine.
<u>Therefore:</u>
30% of A + 30% of T + 20% of C + 20% of G = 100% DNA
Answer:
Aesthetics is about
. You may think of aesthetics as distinctly different from a product’s function, but it’s not. To be considered great design and desirable to users, a product must both function well and exhibit good design with attributes like beauty, smart ergonomics, and a form that aids in function.
Answer:
Anterior Spinothalamic tract
Explanation:
Anterior Spinothalamic tract is located centrally within the spinal cord. They carry sensory information such as touch, pain or pressure to the brain
The interstitial cells in the body produce testosterone for endocrine purposes. The seminiferous tubules' generation of spermatozoa constitutes the exocrine function.
<h3>
What are Endocrine Functions of Testes?</h3>
- The pituitary and hypothalamus regulate the amount of testosterone the testes make and secrete.
- The pituitary gland receives a signal from the hypothalamus to release gonadotrophic chemicals (FSH and LH). The production of testosterone is stimulated by luteinizing hormone. The hypothalamus warns the pituitary gland to produce less LH, which instructs the testes to lower testosterone levels, if too much testosterone is being produced.
- Boys' normal physical growth need testosterone. It is the principal androgen, which is a name for any chemical that promotes and/or supports the development of the male genitalia. Many of the processes that help a boy transition to manhood during puberty require testosterone, including:
- healthy growth of male genitalia
- growth of body and face hair
- reduction in voice volume
- Adam's apple development
