What is the goal of meiosis? How many daughter cells do you have at the end of meiosis?

Biology
1 answer:
tatuchka [14]3 years ago

Answer:

Goal of meiosis: To produce gametes with half the number of chromosomes as compared to the somatic cells.

Each parent cell produces four daughter cells by the end of meiosis.

Explanation:

The goal of meiosis is to produce gametes for sexual reproduction. Since male and female gametes fuse to produce a zygote, each of the gametes should have half the number of chromosomes as compared to the somatic cells to prevent the doubling of chromosomes by the end of each round of sexual reproduction.

Therefore, meiosis produces haploid gametes from diploid gamete mother cells. Absence of DNA replication between meiosis I and meiosis II ensures that the number of chromosomes is halved in the daughter cells of meiosis. Additionally, meiosis also imparts genetic variations to the progeny by the process of crossing over.  

A diploid parent cell enters meiosis I and produces two haploid daughter cells which in turn enter meiosis II to produce a total four haploid daughter cells.

if temperature were available from several stations in canada near the great lakes do you think 15-degree line would form a clos
fomenos

Yes, a 15-degree line would form a closed loop for temperature obtained from several stations in Canada near the Great lakes.

<h3>What is temperature?</h3>

Temperature refers to a measure of the degree of hotness or coldness of a physical body (object). Also, temperature is typically measured by using a thermometer and its units are:

  • Celsius (°C)
  • Kelvin (K)
  • Fahrenheit (°F)

<h3>What is an isotherm?</h3>

An isotherm can be defined as a line that is drawn on a map to join points with the same temperature, so as to show the distribution of temperature in a geographical region on Earth's surface.

In Meteorology, a closed loop is used to show or depict where an air mass is located when drawing isotherms. Thus, a 15-degree line would form a closed loop for temperature obtained from several stations in Canada near the Great lakes.

Is a paper clip a conductor or a insulator
Softa [21]
A metal paper clip would be a conductor since heat energy is easily conducted through metal. If it is off a different material such as plastic it would be a better insulator than a conductor but most paper clips are metal so your answer would be the first sentence.

How does competition shape communities?
Tanya [424]

Answer:

In the short term, what we would call “ecological time scales”, competition shapes communities primarily by limiting population growth. Every population requires and excess of required resources to grow larger, but if another population is taking those resources instead, then their growth is limited. If your competitor is significantly better at securing resources, and is growing larger, your population may find that it is actually too large for the amount of resources it is capable of obtaining, and so will have to shrink down to a level that can be sustained by the amount of resources it can get.

Competition with individuals of your own species also limits the size of your population, even more so than competition with other species. This is because members of the same species have more overlapping sets of resources that they require. Two humans both need houses and water, so they compete for them both, but they don’t have to compete with birds for houses, only water.

In the longer term, called “evolutionary time scales”, competition can change the characteristics of the species that are in competition with each other. Species may evolve to need certain resources less if their competitors are better at obtaining them. This allows those two species to evolve to be more compatible, allowing them to better coexist by making them less competitive with one another.

Evolution won’t change a single species to be able to compete less with members of its own species, but in some cases it can lead to the creation of new species.
