Answer:

The offspring plant must have genotype Rr for flower color (pink flowers) and Ww for seed shape (wrinkled). In fact we know more: we know the R and W came from one parent, so are on the same chromosome, and also the r and w on the other chromosome, from the other parent. We write this RW/rw.

Explanation:

When the genotype of a carnation is heterozygous for the trait (Rr), the result is a pink color that comes from the incomplete dominance of the alleles. In codominance there are two or more dominant alleles.

Think about a petal plucked from its flower. When the petal is removed from the flower, will it remain alive according to

schepotkina [342]

When a petal is plucked from a flower, it will not remain alive for very long. It will soon start to decompose.

Explanation:

To understand this, we need to go back to the act of plucking the flower as such from the plant. The moment a flower is plucked from a plant, it stops receiving any further nutrition from the plant. Whatever nutrients were present in the flower at the time of plucking it will continue to keep it alive and once those nutrients are used up, the flower will start to decompose.

In this case, since the petal is plucked from a flower which already was surviving on limited nutrients, it will decompose very quickly.

According to the characteristics of life, it cannot be considered dead at the time it's plucked. It continues to live, but for a very brief time.

Infection occurs when the host is exposed to pathogens. what type of pathogen uses the cell's metabolism, and replicates itself

vladimir1956 [14]

Answer: Infection occurs when the host is exposed to pathogens. virus uses the cell's metabolism, and replicates itself while destroying the cell or changing the cell's genetic makeup.

Explanation:

A virus is a miniscule pocket of protein that contains genetic material.

Viruses pose a considerable challenge to the body’s immune system because they hide inside cells.
This makes it difficult for antibodies to reach them. Some special immune system cells, called T-lymphocytes, can recognise and kill cells containing viruses, since the surface of infected cells is changed when the virus begins to multiply.
Many viruses, when released from infected cells, will be effectively knocked out by antibodies that have been produced in response to infection or previous immunisation.
Antibiotics are useless against viral infections. So antiviral drugs work differently to antibiotics, by interfering with the viral enzymes instead.

Hence virus are the pathogen that use the cell's metabolism. And replicate itself while destroying the cell or changing the cell's genetic makeup. viruses are so simple that they use their host cells to perform their activities for them
