How are unicellular organisms similar to multicellular organisms?

Unicellular and multi cellular organisms have some similarities and differences between them. The similarities between the two are listed below:

1.One big similarity between unicellular and multi cellular organisms is that the two of them are made up of cells.

2. The two organisms have similar genetic codes; both type of cells has DNA as hereditary material. The genetic code is universal and DNA sequence from a unicellular organism can be reproduced by a multi cellular organism and vice versa.

3. Both unicellular and multi cellular organisms have the same type of cell membrane. The cell membrane are made from phospholipids and they also incorporate different types of proteins.

4. Both organisms also have ribosomes in their cells. The ribosomes are responsible for the synthesis of proteins. Both cells synthesis proteins.

5. Both type of organisms have to obtain energy and nutrients to sustain their growth and energy.

just here for the other one bc they put up with u

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.
