The majority of bacteria have a cell envelope. which component of the cell envelope is found in only some bacterial cells?

lesya [120]

The majority of bacteria have a cell envelope component which serves as an outer compartment.

Explain the Plasma membrane components.

The membrane that divides the interior of the cell from the external environment is known as the plasma membrane, sometimes known as the cell membrane, and is present in all cells.

A cell wall is affixed to the plasma membrane on the exterior of bacterial and plant cells. A semipermeable lipid bilayer makes up the plasma membrane. The movement of materials into and out of the cell is controlled by the plasma membrane.

A cell is protected by its cell membrane, also known as the plasma membrane. Additionally, it offers a stable environment inside the cell. And that membrane serves a variety of purposes. One is to move compounds out of the cell that is harmful as well as nutrients into the cell.

Hence, the correct answer is the outer membrane.

-Huntington's

Juliette [100K]

A pedigree is the representation of family history. 1) I.1, II.2, II.3, II.7, III.3 / 2) Dominant / 3) Six / 4) 2 girls, 1 affected / 5) niece-uncle and grandma-grandson

---------------------------

Huntington's disease is an autosomal dominant affection.

It is expressed by heterozygous individuals, meaning that only one copy of the altered gene is enough to express the phenotype.

The mutated gene is the dominant one.

I will answer these questions according to the attached pedigree.

A pedigree is the representation of family history through which it is possible to follow the inheritance pattern of certain traits.

To correctly interpret a pedigree, we need to consider that,

Squares represent males or men,
Circles represent females or women.

Solid figures represent affected individuals,
Empty figures represent normal individuals.

Roman numbers indicate generations.

Individuals can be identified using numbers, genotypes, names, or others.

1. Which members of the family above are afflicted with Huntington's Disease?

I.1 ⇒ Man of the first generation

II.2, II.3, II.7 ⇒ Two women and one man of the second generation

III.3 ⇒ One woman of the third generation.

2. There are no carriers for Huntington's Disease- you either have it or you don't. With this in mind, is Huntington's disease caused by a dominant or recessive trait?

Huntington's disease is caused by a dominant allele. So a single altered gene is enough to express the affection.

3. How many children did individuals l-1 and 1-2 have?

They had six children.
