Answer:
Mutations leading to the better attachement of virus to the host cell would allow the virus to spread the infection and leave more progeny. The reproductive fitness of mutant viruses would allow the mutation to spread.
Explanation:
1. The organisms with same resource requirement compete with each other. Viruses are not living things but once inside the host cell, they behave like living things. Rapid multiplication of virus overpopulate the host cells.
2. Genetic variations are added to the viral progeny by random errors during replication of the viral genome. These random variations may impart beneficial trait, harmful feature or remain neutral. If a random mutation in the SARS-CoV2 virus allows it to adhere better to the cells of the respiratory system, the virus would be better able to infect these cells to spread the infection. Once inside the host cells, the mutant virus would leave more progeny. On the other hand, the wild type virus that lack this mutation would have lesser chances of entering the host cells and may or may not replicate.
3. The progeny of the mutant virus would compete better with the non mutant ones due to the presence of same mutation.
4. Differential reproduction and more progeny of the mutant virus would spread the mutation among the virus.

Answer:
plants have a weaker cell and is kind of shaped like a octagon and they feed off water and the whitefish cells act like a human cell so everything is different it takes more for the cell to survive and the cell wall is not stuck in one shape it can change its movement
Explanation:
The animal-like parasite plasmodium causes the disease
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 energy stored in food molecules in living cells is gradually released in a series of linked chemical reactions called a ____________.
The area of the cell that is associated with the production of ribosomes is the:
1. nucleolus
2. nucleus
3. nuclear pores
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.

TRUE OR FALSE: Phospholipids that are a part of the nuclear envelope (membrane around the nucleus) can easily move from one part of the cell to another, and may ultimately become part of the cell membrane, the ER, a vesicle membrane, etc. In fact, any phospholipid may be called a "cellular tourist" because it is able to move about to virtually any part of a cell and can even become a part of a cell in a different region of the body! (EXPLAIN WHY)
Answer:
False, because phospholipids are a type of lipids and the nuclear envelope contains nucleic acids.
Explanation:
Hope this helps.
It is true that phospholipids that are a part of the nuclear envelope (membrane around the nucleus) can easily move from one part of the cell to another, and may ultimately become part of the cell membrane, the ER, a vesicle membrane, etc.
What is nuclear envelope made of?The nuclear envelope is made up of two concentric lipid bilayer membranes separated by a 20-40 nm intermembranous space.
In many places, the outer membrane is joined to the rough endoplasmic reticulum. The outer membrane of the nuclear envelope, like the rough ER, is dotted with ribosomes.
The nuclear envelope is made up of two membranes: an outer and an inner phospholipid bilayer. The lumen of the rough endoplasmic reticulum is connected to the thin space between the two layers (RER).
Nuclear pores, which are small channels that run across the nuclear envelope, allow substances to enter and exit the nucleus.
Each pore is lined by a group of proteins known as the nuclear pore complex, which regulates which molecules can enter and exit.
Thus, the given statement is true.
