Is meiosis mitosis happening twice and why would a teacher explain to their students that it is a correct assumption?

Answers

Answer 1
Answer: Meiosis happens when creating sex cells and mitosis is cells that are used for growth and repair of body cells. Meiosis begins with a cell containing 46 chromosomes (2n) and these are replicated to make 92 chromosomes in the cell (4n) these are then divided into two cells each containing 46 (2n) and then again to produce 4 non identical Daughter cells each containing 23 chromosomes (n) however mitosis only divides once so each cell has 46 chromosomes when division is complete and it produces two daughter cells that are genetically identical to the parent and each other

What's a pluton? A. A body of igneous rock that forms from cooling lava on Earth's surface B. A body of igneous rock that forms within Earth's crust C. A body of igneous rock that form as a result of intense heat and pressure D. A body of igneous rock that forms along vents in the ocean floor

Answers

Answer:

B. A body of igneous rock that forms within Earth's crust

Explanation:

Igneous rocks are of two types: intrusive and extrusive. The extrusive igneous rocks are formed by cooling of lava on the earth surface. The intrusive igneous rocks are formed when the magma cools down within the earth's crust. The intrusive rocks are also called as plutonic rocks. Hence, pluton is a body of an intrusive igneous rock.

Answers

A and C are the two benefits that the fungi provide the plants: A. A web of hyphae holds water near the roots. C. The fungi may help trees share carbon compounds through their roots.

What are fungi?

Fungi are a diverse group of eukaryoticorganisms that include microorganisms such as yeasts and molds, as well as macroscopic fungi such as mushrooms and truffles. They obtain nutrients by breaking down organic matter in their environment and play important roles in nutrient cycling and decomposition.

The hyphae create a network that increases the surface area of the root system, which helps plants to absorb more water and nutrients from the soil. The hyphae also help to retain water near the roots, which is important during periods of drought.

The mutualistic relationship is known as mycorrhiza. Some fungi can even help to connect the roots of different plants, allowing them to share nutrients and resources. This network of connections is called the Wood Wide Web. The fungi can facilitate communication between trees and even help to transfer nutrients and chemical signals between them.

What would happen if the population of the bird species shown in the ecosystem in Figure 4-1 were to suddenly decrease?•The grass population would increase
•The fish population would increase
•The fish would occupy the bird's niche
•The grass and fish would compete for resources

Answers

Answer: The fish population would increase.

This is because if the number of birds decrease the number of  fishes would automatically increase as there would be less birds to eat the fishes.

According to trophic pyramid if the number of species at higher tropic level decreases the number of species at lower trophic level increases

  • Rest all the options has no interconnections like grass has nothing to do with the fishes and birds as well
  • Fishes cannot occupy bird's niches because both the niches are different
  • The grass and fish cannot compete for resources because their resources are different

Answer:

The second option which is, "The grass population will increase" is the correct option.

Explanation:

  • In the above picture, a bird is eating a fish from the pond. if the population of birds in a community decrease due to some reasons, then there will be no birds for eating fishes.
  • This will cause an increase in the population of fishes.
  • But there is no connection of grass with the increase and decrease of birds species.
  • In ecological pyramids, Birds (secondary consumers) are high than the fishes (primary consumers).
  • As secondary consumers eat primary consumers.
  • Hence the decrease in secondary consumers will increase the population of primary consumers.

How do animals that don't need care as babies take care of themselves

Answers

They'll grow up with their instincts and the natural world around them. Not all animals need parents to survive. Such as birds, they can learn to fly on their own just by jumping from a height. 
their instincts are what they are borned with, just like you have the instinct to blink or breath. This helps them live in the wild, untamed and free. a learned behavoir is like teaching your dog to  sit or roll over.
