(iv) Measles. Mumps, Diphtheria Polio odd one​

The odd one one is diphtheria

Explanation:

There are very minute living organisms that are able to cause different diseases to human which are found in our environment. These are known are microorganisms. They include:

--> viruses

--> bacteria

--> fungi

These microorganisms are able to establish an INFECTION in its human host when it's able fight and overcome the body defence mechanism of the host.

Diphtheria is the odd one because it's an infection which is caused by BACTERIA organism while other options while includes measles, mumps and polio are caused by VIRUS microorganisms.

BACTERIA are the larger microorganisms with a very simple cell structure where the nucleus is not enclosed within a membrane. While VIRUS are the simplest and smallest microorganisms which do not have a cell structure.

Diphtheria is an infection caused by the bacteria microorganism known as the Corynebacterium diphtheriae. These bacteria are able to produce toxins which is its virulent factor that are poisonous to its host.

Measles is an infection caused by paramyxovirus.

Mumps is an infection caused by mumps virus

Polio is an infection caused by picornavirus.

Therefore, Diphtheria infection is the odd one out.

helicase, i think thats it

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.
