Answer:

Homeostasis typically involves negative feedback loops that counteract changes of various properties from their target values, known as set points. In contrast to negative feedback loops, positive feedback loops amplify their initiating stimuli, in other words, they move the system away from its starting state.

The diagram shows a bacterial cell dividing. What is an ADVANTAGE of this type of reproduction?
Naddika [18.5K]
(Sorry if this is late)

The answer to this is B because it is the only answer choice that is true.

This is actually a quick process, making A incorrect.

C is incorrect because there are no different genes to combine with, since there is only ONE parent cell.

D is incorrect because the offspring are clones. They haven't adapted at all.

Have an awesome day! :)

wolverine [178]

Answer:

Sex Linkage

Explanation:

Sex linkage is the phenomenon in which the expression of genes depends on the gender of the organisms because genes for specific traits are located on the sex chromosomes of organisms.

What are sex chromosomes:

They are usually a pair of chromosomes present in higher organisms like humans and other mammals that combine during fertilization of male and female gametes and determine the sex of offspring. In humans they are X and Y chromosomes and when there is an XX offspring, she will e female and when there will be Xy offspring , he will be male.

Significance:

  • Now there are some genes that are present only on sex chromosomes of the organisms like genes for beard are present in human Y chromosome of men, However,genes found on the X chromosome can be found in either males or females.
  • Sex linked genetic disorders are very common in human males because males receive only one copy of X chromosome while females receive two copies. So only one copy of defective gene is enough for the expression of disease in males while in women  two copies are needed if the trait is recessive.
  • For example: There is a disease called hemophilia in which the blood is unable to clot even after minor injuries and can be life threatening.
  • Hemophilia is an X linked recessive disorder and is an example of sex linked traits controlled by sex linked genes.

Hope it helps!
