Response:
B. Microorganisms have the capability to generate distinct proteins that are beneficial for genetic investigations
Rationale:
Biodiversity encompasses the variety of living organisms present on our planet. It is a crucial aspect of ecosystems since these organisms are interconnected. Hence, a decline in biodiversity will have repercussions for the ecosystem.
When considering biodiversity, a typical person often thinks only of visible organisms, but diversity also exists among microscopic entities.
Human activities are threatening not just larger creatures but also the tiny organisms. Microbes are essential to our existence; for instance, they are utilized by researchers in the fields of genetics and molecular biology. They also produce proteins that are ingested by humans.
Therefore, Option-B is the accurate choice.
A gene is a segment of DNA that typically contains the code for a particular protein influencing a specific trait, while an allele is a segment (a version) of that gene. The correct choice among the options is option "D".
Answer:
99% water, sodium chloride, trace elements of waste, and vitamin C
Explanation:
Eccrine glands are the primary sweat glands present in our body. They are distributed throughout the skin, but are denser on the palms, soles, and scalp.
99% of the secretion from eccrine glands consists of water, with the remaining 1% comprising sodium, small amounts of waste, and a significant quantity of vitamin C being excreted through these glands.
Since the eccrine gland facilitates sweating, it plays a crucial role in regulating body temperature. Given that 99% of its secretion is water, dehydration and fluid loss become significant concerns during heavy sweating.
False; unlike blood, lymph does not move to and from the heart.
