Can organisms plan and willingly change theirmutations in their genes? Why or why not.
simple answer 1 sentence please

The likelihood of an event occurring is described as probability and is denoted as option C.

What is Probability?

This is referred to a branch of mathematics which deals with calculating how likely something occurs.

A common example is the likelihood of a parent giving birth to

offspring with certain types of trait etc.

Answer:

Option A

Percent of the population that has skin pigment but also carries the recessive allele is percent

Explanation:

As per hardy-weinberg equation,

------------- Eq(A)

where

frequency of the homozygous genotype (dominant)

frequency of the homozygous genotype (recessive)

frequency of the heterozygous genotype (recessive)

Also, sum of the allele frequencies at the locus is equal to one.

Thus,   ------------- Eq(B)

Here frequency of recessive allele i.e %

Substituting this in equation B, we get

frequency of dominant allele i.e %

Substituting the value of frequency of both dominant and recessive allele in equation A, we get

Thus, percent of the population that has skin pigment but also carries the recessive allele is percent

Answer:  The Leber's hereditary optic neuropathy (LHON) is caused by defective genes contained in mitochondrial DNA.

Explanation:

LHON is causes the vision loss. This occurs due to mutation in the mitochondrial DNA. The symptoms are not associated vision loss thus it is difficult to predict that which member of family was the carrier of the disease. Some people do not get completely blind. A young male is expected to develop a risk of 50% development of this disease.

Answer:

I hope this will help you:)

Explanation:

Autotrophic organisms are found in kingdom planted

Heterotrophic organisms are found in kingdom animalia

Kingdom monerans has some organisms like Cyanobacteria that can carry out photosynthesis so they are autotrophswhile the other main category of monerans is not capable of photosynthesis so are heterotrophs so this kingdom includes both o gains s

Kingdom protist are heterotrophs and autotrophs because some can prepare food while others cannot

Kingdom fungi has some organisms that can carry out photosynthesis like algae

while other are heterotrophs

Explanation:

de kingdoms where de aiutotrophs nd heterophic belong is known to be bacteria..there is also kingdoms where in dey r also autotrhoic nd dis is plantae kingdom also dere r kingdom there r only hetetrpohs nd these r animalia nd fungai

Answer:

Tight junctions - prevent liquid from seeping between cells

Desmosomes - act as rivets to hold adjacent cells together when epithelial tissue moves

Gap junctions - allow movement of cytosol, ions, and small molecules between animal cells

Plasmodesmata - openings through the cell walls of plant cells that allow adjacent cells to share materials

Explanation:

1) Tight junctions are one of the cell junctions found in animal cells. Tight junctions function to prevent the flow of liquid materials between cells.

2) Desmosomes are another type of cell junctions whose function is to form a connection between two adjacent cells. The structure formed by this connection confers strength upon the tissues involved.

3) Gap junctions are the most commonly found cell junctions found in animal cells that connects adjacent cells allowing the passage of cytosol, ions and other small molecules in them from one adjacent cell to another.

4) Plasmodesmata is a cell junction found in plant cells. They are small openings lying across the cell wall of plant cells whose function is to connect the cells and facilitate the movement of materials from one cell to another.

Final answer:

Tight junctions prevent liquid seepage between cells, desmosomes hold cells together, and gap junctions allow movement between animal cells.

Explanation:

• Tight junctionsprevent liquid from seeping between cells by forming a barrier that tightly seals adjacent cells together, preventing substances from passing through the spaces between cells.

• Desmosomes, on the other hand, act as rivets to hold adjacent cells together when epithelial tissue moves or is subjected to mechanical stress.

• Gap junctions, found in animal cells, allow the movement of cytosol, ions, and small molecules between cells, enabling communication and coordination.

• Plasmodesmata, found in plant cells, are openings through the cell walls that link adjacent cells and allow them to share materials, such as water, nutrients, and signaling molecules.
