Meiosis is a form of cell division that reduces the chromosome number of the daughter cells from diploid to haploid and introduces variation into the daughter cells. a.true b.false

Answers

Answer 1
Answer: a. true

Meiosis is indeed a form of cell division that reduces the chromosome number from diploid (two sets of chromosomes) to haploid (one set of chromosomes) in the daughter cells. This reduction in chromosome number is essential for sexual reproduction and genetic diversity. Additionally, meiosis introduces genetic variation through processes such as crossing over and independent assortment.
Answer 2
Answer:

Final answer:

Meiosis is a form of cell division that reduces the chromosome number of daughter cells from diploid to haploid and introduces variation. It involves two rounds of division, resulting in four daughter cells.

Explanation:

Meiosis is a form of cell division that reduces the chromosome number of the daughter cells from diploid to haploid and introduces variation into the daughter cells. It consists of two rounds of cell division, resulting in four daughter cells, each with half the number of chromosomes as the original cell. This process is important for sexual reproduction and the production of gametes (sperm and eggs).

What is ecological niche?

Answers

An ecological niche is the role and position a species has in its environment; how it meets its needs for food and shelter, how it survives, and how it reproduces. A species' niche includes all of its interactions with the biotic and abiotic factors of its environment. Hope i helped! :)

Answer:

The ecological Niche is a function of a species serve in its ecosystem; including what it eats, and how it behaves.

If you don't understand, here is another explanation.

The ecological niche is about an organism living in an ecosystem with biotic and abiotic and how it behaves with it.

Answers

D. Temperature readings are made late in the day, when everyone is tired and eager to go home.

Errors are what makes your measurement invalid and unreliable. There are two types of error which is called the systematic error and the random error. Each error has different sources. Words that were mentioned –invalid and unreliable are very important key aspects to determine that your measure is truly accurate and consistent. Some would recommend using the mean method, doing three trials in measuring and getting their mean, in response to this problem.

How would clearing a forest to plant corn affect an enviroment?

Answers

Clearing a forest to plant corn would have several impacts on the environment. Firstly, it would result in the loss of habitat for a variety of animal and plant species that live in the forest, leading to a reduction in biodiversity.

What is corn plant?

Corn, also known as maize, is a cereal crop that is widely grown throughout the world. It is a member of the grass family and is primarily used as a food crop for both humans and animals

Secondly, it would lead to soil erosion, as the trees and other vegetation that previously held the soil in place would be removed, and the exposed soil would be more susceptible to erosion by wind and rain.

This would result in a loss of soil fertility, which would require increased use of fertilizers to maintain crop yields.

Additionally, the deforestation would increase carbon emissions, contributing to climate change. The removal of trees would also reduce the ability of the forest to absorb and store carbon dioxide from the atmosphere through photosynthesis.

Finally, clearing the forest would also impact the water cycle, potentially leading to changes in rainfall patterns and the drying up of nearby rivers and streams.

It would affect our environment very badly. The following reasons are why it is bad: 1)Trees are our main supply of oxygen. 2) Corn is slow at converting carbon dioxide into oxygen. 3) Many wildlife creatures (plants and animals) need that ecosystem to live.
