The biological species concept is least relevant to which of the following groups of organisms?
Luba_88 [7]
<h2>b) is the correct option </h2>

Explanation:

The biological species concept defines a species as a group of individuals living in one or more populations that can potentially interbreed to produce healthy, fertile offspring

  • The biological species concept connects the idea of a species to the process of evolution
  • Because members of a species can interbreed, the species as a whole has a common gene pool, a collection of gene variants
  • In order to be considered to be a single species in the biological species concept, a group of organisms must produce healthy, fertile offspring when they interbreed
  • In some other cases, organisms of different species can mate and produce healthy offspring, but the offspring are infertile, can’t reproduce

Hence it includes the groups which are reproductively isolated so asexual fungi will be least relevant to this group

Select all that apply. Choose the cells that are diploid. egg nerve bone sperm muscle
Natali5045456 [20]
The diploid cells in this case include nerve cell, bone cell and muscle cell. A diploid cell is a cell that contains two sets of chromosomes, which is double the haploid chromosome number. They include all the somatic cells with exception of germ line cells. Gametes are haploid cells meaning they only have one set of chromosomes. During sexual reproduction, gametes (sperm and egg cells) fuse at fertilization to form a diploid zygote which develops into a diploid organism.

In this scenario, the plant on the left has an opaque cap that only covers the coleoptile (shoot tip), while the plant on the ri
denis23 [38]

Answer:

The plant on the left does not accumulate significant photochlorophyll or carotenoids, so it will become very pale on the shoot tip, while the plant on the right will continue to grow upward as auxin is uniformly distributed around the tip of the right plant.

Explanation:

Phototropism is the orientation of a plant in response to light, either towards the source of light or away from light. Positive phototropism is growth towards light, while negative phototropism is away from light.

Auxin are substances that promote and regulate the growth and development of plants. Auxin escapes light making the area in the shade elongate more so the plant tip moves towards the light.
