When we talk about evolution we come across the process of natural selection. Genetic variation is always required for the natural selection. A change or variation in the genes may help the individuals in a population to better adapt to the environment. Such changes may be brought by mutations or random mating in the population. Such variations help in the survival of the population by allowing them to adapt to changing environmental conditions.

Describe how plants absorb photons of light energy.
Alik [6]

Answer: When a plant is exposed to light, photons of appropriate wavelength will strike and be absorbed by the pigment-protein complexes arrayed on the thylakoid membranes. When this happens, the energy of the photon is transferred to the pigment molecule, thus causing the pigment to go into an electronically excited state. :)

It has been hypothesized that fungi and plants have a mutualistic relationship because plants make sugars available for the fung
Lilit [14]

Option (B) Radioactively labeled sugars produced by plants eventually show up in the fungi with which they are associated is correct.

The best evidence in support of this hypothesis is that radioactively labeled sugars produced by plants eventually show up in the fungi with which they are associated.

<h3>How Fungi and plants are related? </h3>
  • The first is that they are both eukaryotic, which means that their cells have a nucleus and membrane-bound organelles, and that they both belong to the Eukarya domain.
  • They are both immobile, have cell walls, and are frequently multicellular, meaning they are made up of several cells.
  • Mycorrhizae are plant and fungal symbiotic relationships.
  • As fungi infiltrate a host plant's root system, the plant's capacity to absorb water and nutrients increases, and the fungus has access to the plant's photosynthesis-produced carbohydrates.
  • According to computational phylogenetics, fungus and other eukaryotes are more closely related to one another than plants are to us.
  • The clade of mammals and fungi known as opisthokonta is named for a solitary, posterior flagellum that existed in their most recent common ancestor.

otez555 [7]

Answer:

The structures that are responsible for the movement of chromosomes to the center of the cell in metaphase is the spindle fibers, the cell attaches the centromeres to the spindle fibers to pull the sister chromatids to the center

In anaphase the sister chromatids are separated at the centromere and are pulled to the opposite poles of the cell by the spindle fibers
