Which of these statements is not correct? which of these statements is not correct? quick freezing kills all vegetative bacterial cells. shorter-wavelength radiation is more suitable for microbial control than longer-wavelength radiation. uv radiation is useful for disinfecting surfaces. filtration can remove all bacteria and viruses from a solution if the pore size is small enough?

The freezing causes the inactivation of the bacteria. In case of freezing the, bacterial enzymes are not able to function, this causes the inactivation of bacterial growth and function, but once the favourable circumstances are present, these enzymes get activated again, and the bacteria is fully functional.  

So, saying that freezing kills all the bacteria is incorrect as it only deactivates the bacterial activity.

Shorter wavelengths are known to kill the bacteria more effectively, as it directly targets the genetic material of the bacteria. Ultraviolet radiations are used in many industries and laboratory processes to kill the bacteria.  

The bacteria can also be filtered, if the pore size is smaller enough to inhibit the bacteria pass through it. Although, it is a little difficult, but it works.  

an individual’s sex (i.e., whether they are a male or female) is determined by the sex chromosomes. most people have two sex chromosomes, one that is inherited from their mother and one that is inherited from their father. typically, females have two x chromosomes (xx) and males have one x chromosome and one y chromosome (xy). conditions caused by changes (“mutations”) in genes located on the x chromosome are considered x-linked.

x-linked recessive inheritance

most x-linked conditions are recessive. this means that in a person with two x chromosomes (most females), both copies of a gene (i.e., one on each x chromosome) must have a change or mutation whereas in a person with one x chromosome (most males), only one copy of a gene must have a mutation. a female with a mutation in one copy of a gene on the x chromosome is said to be a “carrier” for an x-linked condition. a male with a mutation in a gene on the x chromosome is typically affected with the condition. because females have two copies of the x chromosome and males have only one x chromosome, x-linked recessive diseases are more common among males than females. however, x-linked recessive diseases can occur in both males and females.

for x-linked recessive disorders, an unaffected carrier mother who has a mutation in a gene on the x chromosome can transmit either the x chromosome with this mutation or a “normal” x chromosome to her children. if the father is unaffected, none of her daughters will be affected and all of her daughters will be unaffected—since they will inherit at least one normal x chromosome from their father. however, each daughter will have a 50% chance of being an unaffected carrier like her mother and a 50% chance of both x chromosomes being normal.

stimulus is a change in the environment that causes an organism to react. the response is the reaction to the stimulus. some examples of stimuli for zebras are drought, to many predators, and bad feeding grounds such as dead grass or plants. zebras respond to stimuli just like all other living organisms
