What does mitosis do that the cell would do wrong if it just split down the middle in cell division?

Answers

Mitosis is when a DNA error, aka mutation, occurs in a body cell. When cells divide, it needs a copy of the DNA. During DNA replication, that error can cause the instructions for building proteins to differ. The change can not affect offspring. Meiosis is the same situation, but in sex cells. This can be transferred to offspring.

At location B in the diagram, the granite is likely to be formed. so, the correct option is (B).

What is Granite?

Granite is a coarse-grained intrusive igneous rock which is composed of quartz, alkali feldspar and plagioclase. It is formed from magma with a high content of silica and alkali metal oxides which cools slowly and solidifies underground.

It is a light-colored plutonic rock found throughout the continental crust, mainly in mountainous regions consisting of coarse grains of quartz, potassium feldspar and sodium feldspar. All these minerals make up more than 80% of the rock.

Granite is used in counter tops, floor tiles, paving stone, curbing, stair treads, building veneer, and cemetery monuments.

Thus, at location B in the diagram, the granite is likely to be formed. so, the correct option is (B).

Answers

Answer:

Malaria is the answer

Explanation:

The animal-like parasite plasmodium causes diseases like malaria.

What is malaria?

A parasite that frequently infects a particular species of mosquito that feeds on people can result in a serious and occasionally fatal disease known as malaria.

An obligatory parasite of insects and vertebrates, Plasmodium is a genus of unicellular eukaryotes. The parasite Plasmodium, which causes malaria, is spread via the bite of an infected mosquito.

Malaria often causes severe disease, including high fevers, shivering chills, and flu-like symptoms. Through the bites of female Anopheles mosquitoes carrying the parasites that cause malaria, people can contract this potentially fatal illness. It can be avoided and treated.

Therefore, malaria is brought on by the parasite plasmodium, which resembles an animal.

The area of the cell that is associated with the production of ribosomes is the:
1. nucleolus
2. nucleus
3. nuclear pores

Answers

Answer:

Nucleolus

Explanation:

This is a more technical answer. The Nucleolus is located inside the nucleus and this is the location where the ribosomes are produced. They then leave through the nuclear pores to be sent out into the cell.

The area of the cell that is linked with production of ribosomes is nucleolus. The correct option is 1.

What is nucleolus?

The nucleolus is a circular shape within the nucleus of cells that produces and assembles the cell's ribosomes. Ribosomal RNA genes are also transcribed in the nucleolus.

The nucleolus has the most visible realm in the nucleus of a eukaryotic cell, and its basic task is ribosomal RNA (rRNA) melding and ribosome biogenesis.

The nucleolus, as the site of ribosome biogenesis, is critical to cell metabolic activity.

It is made up of ribosomal DNA (rDNA), which is found in tandem arrays in nucleolus event coordinator regions.

The nucleolus synthesizes ribosomal subunits from proteins and ribosomal RNA, or rRNA.

It then starts sending the subunits to the rest of the cell, where they join together to form complete ribosomes.

Thus, the correct option is 1.

why CO2 still being produced for a few minutes after death?

Answers

Explanation:

As best as anyone can gauge, cell metabolism likely continues for roughly four to 10 minutes after death, depending on the ambient temperature around the body.

During this time period, oxygenated blood, which normally exchanges carbon dioxide with oxygen, is not circulating. Thus, cell respiration—which uses oxygen to make cellular energy while creating carbon dioxide as a by-product—creates carbon dioxide that is not transported out of the cell. This lowers the pH of the cell, resulting in an acidic intracellular environment. This acidic environment causes intracellular membranes to rupture—including those around the cell's lysosome, which contains enzymes for digesting everything from proteins to fats and nucleic acids. Once the membranes have burst, these enzymes are released and begin to digest the cell from the inside out. This process is known as autolysis (or self-digestion).
