Answer:
It is also referred to as the phospholipid bilayer or the plasma membrane, It helps cells maintain homeostasis, It is selectively permeable; that is allows some substances through but not others
Explanation:
a. I don't know how to explain other names for the cell membrane but they are it, as the cell membrane is a bilayer composed of phopholipids and it is also called a plasma membrane
b. The cell membrane has many structures on it that facilitate nutrient transport in and out of the cell (ex: protein pump). nutrients of higher concentrations would like to move through lower concentrations, and it achieves this by moving across the cell membrane in or out of the cell, maintaining homeostasis
c. Some substances such as NaOH use pumps on the cell to move in or out of it, it can't get in or out without using pumps since they are so big, so the cell can choose when the cell wants it's nutrients or if it dosen't

which was TRUE garding the structures of DNA and RNA, and how do they relate to replication and the expression of genes?
A.Replication involves copying a whole molecule to produce a double-stranded molecule of DNA. RNA is a single stranded and is transcribed from a portion of one strand of DNA to produce a protein
B. Replication involves copying a whole molecule to produce a double-stranded molecule of RNA. DNA is a single stranded and if transcribed from a portion of one strand of RNA to produce a protein
C. Replication involves copying a portion of one strand to produce a single-stranded molecule of RNA. DNA is double stranded and is produced by transcribing a whole molecule of RNA to produce a protein
D. Replication involves copying a portion of one strand to produce a single-stranded molecule of DNA. RNA is double stranded and is produced by transcribing a whole molecule of DNA to produce a protein.
Answer:
A.Replication involves copying a whole molecule to produce a double-stranded molecule of DNA. RNA is a single stranded and is transcribed from a portion of one strand of DNA to produce a protein
Replication involves copying a whole molecule to produce a double-stranded molecule of DNA. RNA is a single stranded and is transcribed from a portion of one strand of DNA to produce a protein.
What is Replication?
A double-stranded DNA molecule is copied to create two identical DNA molecules through the process of DNA replication. Because every time a cell splits, the two new daughter cells must have the same genetic material, or DNA, as the parent cell, replication is a crucial process.
The ability of each DNA strand to function as a template for duplication is essential to the replication process. DNA double helix unwinding occurs at specified locations, known as origins, where DNA replication begins.
The production of a primer, a brief section of RNA that serves as the beginning point for the synthesis of fresh DNA, follows. The DNA is then replicated by a protein called DNA polymerase by matching bases to the original strand.
Therefore, Replication involves copying a whole molecule to produce a double-stranded molecule of DNA. RNA is a single stranded and is transcribed from a portion of one strand of DNA to produce a protein.

Mammalian erythrocyte lacks nucleus. Why? Give reason.
Explanation:
Complete answer:
A mature erythrocyte lacks nucleus and mitochondria so as to make a place for the accommodation of more hemoglobin and hence more oxygen molecules. Lack of such organelles also provides the peculiar biconcave appearance of RBCs that aids in efficient diffusion. Young mammalian RBCs are nucleated.
In Plants, the cell wall typically occurs
not at all (it's only found in animal cells)
O just outside of the central vacuole
O just outside of the nuclear envelope (nuclear membrane)

Please answer quickly!There are _____ pair(s) of autosomes and _____ pair(s) of sex chromosomes in a human somatic cell.
A. 2;44
B. 1:22
C. 44;2
D. 22;1
Answer:
D. 22;1
Explanation:
A cell can be defined as the fundamental or basic functional, structural and smallest unit of life for all living organisms. Some living organisms are unicellular while others are multicellular in nature.
A unicellular organism refers to a living organism that possess a single-cell while a multicellular organism has many (multiple) cells.
The human somatic cell is made up of 46 chromosomes which are sub-divided into 22 pairs of autosomes and a pair of sex chromosomes (X and Y). An autosome is one of the numbered chromosome that is typically not a sex chromosome.
On the other hand, sex chromosomes (X and Y) are responsible for determining the gender or sex of living organisms such as humans.
Hence, there are 22 pairs of autosomes and 1 pair of sex chromosomes in a human somatic cell.

An individual always has two alleles for the same gene (one on each chromosome). Which statement is true?
a)A person's two alleles are always different
b)A person's two alleles are always the same.
C)A person's two alleles may be the same, and they may be different
Answer:
A
Explanation:
An individual always has two alleles for the same gene (one on each chromosome). The statement which is true is "a person's two alleles may be the same, and they may be different". Thus, the correct option is C.
What are alleles?An allele can be referred to as an alternative form of a gene. An allele is located at a specific position on a specific chromosome. These alleles can be passed on from the parents generation to their offspring through the process of sexual reproduction.
The presence of two identical alleles at a particular gene locus (chromosome) is referred to as a homozygous genotype. This may include two normal alleles or two alleles that have the same variant. The presence of two different alleles at a particular gene locus is referred to as a heterozygous genotype.
Therefore, the correct option is C.

Children inherit half of their genes from parents. Explain Why?
Answer:
This is because the two parents share one or more common ancestors and so carry some of the same genetic material. If both partners carry the same inherited gene change, their children are more likely to have a genetic condition.
Answer:
yes
Explanation:
The chromosomes in cells line up in pairs and exchange bits of genetic material before forming an egg or sperm cell. Each mature egg and sperm then has its own specific combination of genes, which means children will inherit a slightly different set of DNA from each parent.
