Trick question. Bacteria do not have cell walls. They barely have cell membranes. The second blank might be either chemosynthetic (break down chemicals for food) or photosynthetic (generate food from sunlight).

Suppose a male organism has a diploid chromosome number of 6. These chromosomes could be represented as A,a, B, b, C, and c wher
KatRina [158]

Answer:

A. The haploid set of n is ABC

B. ABC, ABc, AbC, aBC, abc, abC, aBc, Abc.

Explanation:

A diploid cell is a cell that comprises of two complete sets of chromosomes. This is double the haploid chromosome number. Each pair of chromosomes in a diploid cell is noted to be a homologous chromosome set. A homologous chromosome pair consists of one chromosome donated from one parent and one from the other parent. This number is represented as 2n. It varies in different organisms. A diploid cell replicates via mitosis. It preserves its diploid chromosome number by making an identical copy of its chromosomes and distributing its DNA in an equal manner between two daughter cells.

Haploid refers to a cell that contains a single set of chromosomes. Gametes are made up of half the chromosomes contained in normal diploid cells of the body, these are also known as somatic cells. Haploid gametes are produced during meiosis. Meiosis is a type of cell division that reduces the number of chromosomes in a parent diploid cell by half.

Therefore,

Karyotype of this organism is designated as AaBbCc.

AaBbCc is the diploid set (2n).

Hence ABC or abc are the haploid set (n).

B. The eight different combinations of these chromosomes that could possibly be produced by spermatogenesis in this male are:

ABC, ABc, AbC, aBC, abc, abC, aBc, Abc.

Why would cells die if they were unable to make (or otherwise obtain) the amino acid arginine?
kumpel [21]

Answer: Arginine is an amino acid that is incorporated into proteins. So if cells can not make or obtain arginine, the cell can not make proteins needed for survival.

Explanation:

Arginine is an amino acid used to build proteins, and it is classified as a semiessential or conditionally essential amino acid.

Proteins are large molecules consisting of long chains of amino acids. They perform many functions such as catalysing metabolic reactions, providing structure to cells and organisms, and transporting molecules, among many others.

Most notably, arginine is part of proteins that play an important role in many different processes such as cell division, immune function, wound healing and the release of hormones. <u>Without this amino acid, the cell cannot manufacture the proteins necessary for proper functioning</u>. So the cell dies because it cannot function properly.
