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:
pa heart follow back follow me brainliest me please
Explanation:
Deoxyribonucleic acid (DNA) and Ribonucleic acid (RNA) are perhaps the most important molecules in cell biology, responsible for the storage and reading of genetic information that underpins all life. They are both linear polymers, consisting of sugars, phosphates and bases, but there are some key differences which separate the two1. These distinctions enable the two molecules to work together and fulfil their essential roles. Here, we look at 5 key differences between DNA and RNA. Before we delve into the differences, we take a look at these two nucleic acids side-by-side.

how can use of fertilizers affect respiratory health?
a) they directly produce gas particles of air pollution
b) they can contaminate bodies of water
c) they can contain contaminants that can enter the air during storms or high winds
d) fertilizer use does not impact respiratory health
Answer: C) They can contain contaminants that can enter the air during storms or high winds.
Explanation: A is wrong because I got it wrong (Sorry, can't give much explanation there).
B is wrong because water contamination does not directly relate to respiratory health.
D is wrong because fertilizers can impact respiratory health (Explanation seems lack-luster, but I feel like this is common sense).

Why do you think hemoglobin levels vary with altitude?
Answer:
haemoglobin in blood increases at high altitude. This is one of the best-known features of acclimatisation (acclimation) to high altitude. Increasing the amount of haemoglobin in the blood increases the amount of oxygen that can be carried.

PLEASE HELP!!!!! Describe in detail the process of dna replication
Answer:
DNA replication is the process by which a double-stranded DNA molecule is copied to produce two identical DNA molecules. The replication process relies on the fact that each strand of DNA can serve as a template for duplication. DNA replication initiates at specific points, called origins, where the DNA double helix is unwound. A short segment of RNA, called a primer, is then synthesized and acts as a starting point for new DNA synthesis. An enzyme called DNA polymerase next begins replicating the DNA by matching bases to the original strand. Once synthesis is complete, the RNA primers are replaced with DNA, and any gaps between newly synthesized DNA segments are sealed together with enzymes. Once the DNA in a cell is replicated, the cell can divide into two cells, each of which has an identical copy of the original DNA.

which laboratory tools are useful when looking at internal organs of an earthworm
Answer:
An earthworm's internal organs can be viewed through a dissecting microscope. This type of microscope allows enhanced observation of objects that are too large for a compound microscope. Because the magnification is low, this microscope cannot be used to examine cells.
how can genetically modified bacteria with human genes be used to treat human diseases
In the 1980s, scientists discovered how to produce human insulin by transplanting the genetic information for the human insulin hormone from a human cell, into the DNA of the E. coli bacterium. This reprograms the bacteria to produce insulin, in just the same way as they make their own proteins.

how far does a car travel in 0.75 h if it's moving at a constant speed of 88 km/h
Answer:
Distance = 66 kilometers
Explanation:
Given the following data;
Time = 0.75 hour
Speed = 88 km/h
To find the distance traveled by the car;
Distance = speed * time
Substituting into the equation, we have;
Distance = 88 * 0.75
Distance = 66 kilometers.
Therefore, the car will travel a distance of 88 kilometers.

What does this pyramid tell us about the population?
The answer is A. The population is growing.
The pyramid tells us that population is growing continuously, the growth of population is equal in both male and female population.
What is population?Population is defined as the quantity or population of people living somewhere who are a particular social, cultural, economical, ethnic, or racial category. Making decisions can be aided by knowledge of how population parameters, such as size, regional distribution, age structure, or birth and death rates, vary over time.
The pyramid is used to show the growth in population of a country or population of the city. In the pyramid the growth of population is equal in both male and female population. The pyramid shows that the population of older generation is less than the population of younger generation peoples.
Thus, the pyramid tells us that population is growing continuously, the growth of population is equal in both male and female population.
