<h2>Concept of biological species</h2>

Explanation:

  • Determine whether peoples from one populace will interbreed with people from the other populace when brought into one another's local environments
  • An animal category is a gathering of individual living beings that interbreed and produce fruitful, practical posterity. As indicated by this definition, one species is recognized from another when, in nature, it isn't feasible for matings between people from every specie to create prolific posterity
  • Individuals from similar species share both outer and inward qualities that create from their DNA. The closer relationship two living beings share, the more DNA they share for all intents and purpose, much the same as individuals and their families. Individuals' DNA is probably going to be more similar to their father's or mother's DNA than their cousin's or grandparent's DNA. Living beings of similar species have the most significant level of DNA arrangement and, subsequently, share attributes and practices that lead to effective propagation

Which of the following statements BEST defines vestigial structures? :
ZanzabumX [31]

Answer:

Structures that are still present but currently serve little to no purpose

Explanation:

<em>Vestigial structures/organs are general defined as structures/organs that are present but poorly developed without any functional use in the present living organisms but thought to have been fully developed and functional in their ancestors.</em>

Fully developed and functional organs gradually become less developed and non-functional across generations as the environment keeps changing and organisms found lesser use for the organs. An example includes the <u>caudal vertebrae</u> found in man which is kind of useless but thought to have been fully developed and functional in the ancestors of man - the monkeys.

<u>Vestigial organs are often used as one of the morphological evidence of the evolution of living organisms.</u>

Why do warmer and wetter biomes have higher net primary productivity
Andrej [43]
<span>biomes vary in their rates of net primary production-biomass that remains after cellular respiration limited by sunlight and nutrients available In general, warmer and wetter biomes have higher net primary productivity than colder and drier biomes. The reason for this trend is that plants require sunlight, water, and temperatures warm enough to grow. This is true even in aquatic ecosystems, where sunlight and the availability of nutrients determine the level of net primary productivity.</span>
