what would happen to the planet if all oxygen breathing organisms became extinct and only plants remained on the earth

Biology

Many plants depend on animals primarily insects for pollination and sexual reproduction. If the animals (insects that pollinate) most flowering plants would be unable to reproduce and would go extinct.

Both plants and animals undergo cellular respiration producing Carbon Dioxide. Animals produce only Carbon Dioxide while plants produce both Carbon Dioxide and Oxygen. If animals went extinct there would be less Carbon Dioxide to support photosynthesis and more complex plants would have a difficult time adapting to the reduced levels of Carbon Dioxide.

Plants that survived the extinction of animals would be much simpler than presently complex plants.

Perhaps some plants would become predators of other plants to absorb the nitrogen content of other plants because of the lack of animals to engage in the recycling of nitrogen content.

Which connective tissue layer directly surrounds each axon in a nerve?
gregori [183]

Answer:

Endonerium

Explanation:

The endoneurium (also called endoneurial channel, endoneurial sheath, endoneurial tube, or Henle's sheath) is a layer of delicate connective tissue around the myelin sheath of each myelinated nerve fiber in the peripheral nervous system. Its component cells are called endoneurial cells.The endoneuria with their enclosed nerve fibers are bundled into groups called nerve fascicles, each fascicle within its own protective sheath called a perineurium. In sufficiently large nerves multiple fascicles, each with its blood supply and fatty tissue, may be bundled within yet another sheath, the epineurium.

What is the probability that a seed from a parent plant of genotype Rr will carry the r gene
daser333 [38]
The answer is 50 percent.

Parent plant of genotype Rr will in meiosis produce haploid gametes which will carry either R allele or r allele. Since there are only two possibilities R or r, the probability that seed will get r gene is 1 of 2. This can be presented as 1/2, which is 50%.
