Explanation:
Coronaviruses are viruses from the family Coronaviridae (Order Nidovirales), which are structurally composed of positive-sense single-stranded RNA (ssRNA) genomes with a size of approximately 25 to 33 kilobases. Since the coronavirus genome consists of an ssRNA, they can be directly translated into protein inside infected host cells. The coronavirus that has caused the recent pandemic can enter into host cells through its spike (S) glycoprotein which binds to the Angiotensin-converting enzyme 2 (ACE2) receptor. Subsequently, this virus exploits the host molecular machinery to encode an RNA polymerase which is used to generate RNA from an RNA template. Finally, these RNAs are translated into all viral components (structural proteins) and new viruses are recruited to infected cells.

A heterozygous female with long whiskers mates with a heterozygous male with long
whiskers... W=long whiskers w=short whiskers
What is the PHENOTYPIC RATIO of the offsprings?
Answers
Answer:
3 long whiskers: 1 short whiskers
Explanation:
This question involves a single gene coding for whiskers length in a certain animal. The allele for long whiskers (W) is dominant over the allele for short whiskers (w). This means that a heterozygous individual (Ww) will possess a long whisker.
According to this question, a heterozygous female with long whiskers (Ww) mates with a heterozygous male with long whiskers (Ww). The proportion of offsprings that will be produced from this cross (see punnet square) is as follows:
WW, Ww, Ww, ww
WW, Ww, Ww offsprings will possess a long whisker while 'ww' offspring will possess a short whisker. Hence, the phenotypic ratio will be 3 long whiskers: 1 short whiskers

25% probability of the child to be affected. 0% chances to be affected.Explanation:
Due to technical problems, you will find the complete answer and explanation in the attached files
The probability of having a child having sickle cell anemia can be obtained form Mendelian genetics.
Sickle cell anemia (SCA) is a human genetic disorder that causes the red blood cells to be sickle shaped leading to the clotting of blood in the sufferers and frequent health crisis.
If one parents do not have the disorder but each has one parent that has the disorder, then it follows that each parent has the recessive allele and there is a 25% percent chance that their child could have the disorder.
If the man is affected by the disorder and the woman has no family history of the disorder, then there is a zero percent chance of having a child with the disorder.

Answers
Intensive agriculture is resulting in the loss of ecosystem and is contributing to global warming.
• An agricultural mechanization and intensification system, whose main objective is to increase the productivity from the accessible land via several means like heavy use of chemical fertilizers and pesticides is known as intensive agriculture.
• The intensive agriculture is generally aimed to feed large population of humans, however, the method has contributed as one of the biggest threat to global environment, as it is resulting in the loss of ecosystem and global warming.
• It is accountable for the 80 percent of the tropical deforestation and emergence of novel parasites and reemergence of the parasites, which were under control at one time.
• The intensive farming hampers the beneficial plants and insects, and depletes and degrades the soil it relies upon.
• It is resulting in soil erosion and is resulting in the genetic erosion of the livestock species and crops around the globe.
Thus, intensive farming in order to feed large populations is eradicating the world agriculture slowly and gradually.

facts about nitrogen
Answers
Answer:
Nitrogen is the chemical element with the symbol N and atomic number 7. It was first discovered and isolated by Scottish physician Daniel Rutherford in 1772. Although Carl Wilhelm Scheele and Henry Cavendish had independently done so at about the same time, Rutherford is generally accorded the credit because his work was published first. The name nitrogène was suggested by French chemist Jean-Antoine-Claude Chaptal in 1790 when it was found that nitrogen was present in nitric acid and nitrates. Antoine Lavoisier suggested instead the name azote, from the Greek"no life", as it is an asphyxiant gas; this name is instead used in many languages, such as French, Italian, Russian, Romanian, Portuguese and Turkish, and appears in the English names of some nitrogen compounds such as hydrazine, azides and azo compounds.

A number of studies are carried out in order to verify if there is a relation between the death rate by cardiac diseases ánd the cholesterol level in the blood.The results are shoen in the adjacent graph..
1) explain the relation between the level of blood cholesterol and the risk of cardiac accident
2) firmulate the hypothesis tested in this study
3) what do you conclude concerning the formulated hypothesis?
Answers
Answer:
The correct answer is :
1. increase in cholesterol level leads to more death due to cardiac disease.
2. Hypothesis: "if the cholesterol level is high in an individual, then the risk of death due to cardiac disease is high"
3. Everyone should limit or control their cholesterol level to avoid cardiac disease or it might be lethal.
Explanation:
In this graph, it is represented that there is an increase in the deaths due to cardiac disease with the increase in the cholesterol in the body. The death increase slowly up to 2.5 gL and after that, there is a huge spike in death, which explains that the higher the cholesterol level higher the chances or risk of death due to cardiac disease.
Hypothesis: "if the cholesterol level is high in an individual, then the risk of death due to cardiac disease is high"
On the basis of this one should control its body cholesterol to avoid the chances of cardiac disease as it may lead to death.

Refer to the food web above to answer the following: hunting has significantly reduced the snake population. Explain at least two possible effects this will have on the ecosystem.
Answers
Answer:
I would need to see the food web to provide accurate answers; but,
mouse, rat, small animals, herbivores population would increase.
Anything that the snake eats would increase in population.
Explanation:
Anything that eats the snake would decrease.
The reduction of the snake population due to hunting in the food web can result in an increase in the population of prey species and a disruption in the energy flow of the ecosystem.
Explain how an increase in the population of prey species can reduce snake population?Snakes are predators and they play an important role in regulating the population of their prey species, such as rodents and insects. With the reduction in the snake population, the number of prey species may increase, leading to a possible imbalance in the ecosystem.
This can lead to an increase in the population of other predators or a decrease in the population of prey species that are lower in the food web.
Disruption in energy flow: Snakes occupy an important trophic level in the food web, and their removal can disrupt the flow of energy and nutrients in the ecosystem.
This can lead to a cascading effect on other species in the food web, as their food sources and predators may be affected. For example, if the snake population declines, the population of the animals they prey on may increase, leading to overgrazing or competition for resources.
Additionally, if snakes are a food source for other predators, the decline in the snake population can affect the survival and reproduction of these predators.

Answers
Answer:
.0625 or 6.25%
Explanation:
Find the probability for the plant to have pointed leaves. If the two parent plants are heterzygous, then the likelihood the plant has a recessive characteristic is 25%, 1/4, or .25 for our calculations.Find the probability for the plant to be pink. If the two parent plants are heterzygous, the likelihood the plant has another recessive characterisitc is again 25%, 1/4, or .25 for our calculations.Multiply them together. (1/4)*(1/4)=(1/16) or .0625, or 6.25%
