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.
Are microwaves useful of harmful to humans?
Answer:
no who say this no harmful for humans
Answer:

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.

Are genetic mutations avoidable? Explain.
Answer:
Mutations happen in our cells all the time. It's actually how all humans grow and change. The vast majority of mutations are harmless. Thus, they aren't avoidable.
Mutations occur in our cells all the time. It's how all humans grow and transform. The vast bulk of mutations is harmless. Therefore, they aren't avoidable.
What are Genetic Mutations?
The permanent transmissible difference in the genetic material. An individual exhibiting such a transformation. A point mutation is a mutation resulting from a modification in a single bottom pair in the DNA molecule.
Any alteration in a nucleotide succession of DNA is called a mutation. Chromosomal, dependent, and gene mutations are some of the illustrations of different kinds of genetic mutations.

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.

50% of the gametes will be AaBbCcDd.
B)
1/16 of the gametes produced will be ABcd.
The individual could make gametes that contain ABCD.
D)
The individual could make gametes abcd half of the time.
E)
Only dominant traits will be present in the gametes from a heterozygous
individual
Answer: B,C
Explanation:
I did just did the USA test prep
The outcomes of meiosis and the potential gamete combinations that could form from the genotype for an individual who is AaBbCcDd:
B) 1/16 of the gametes produced will be ABcd. C) The individual could make gametes that contain ABCD.A gamete that is formed by the meiosis, is a reproductive cell which has haploid set of chromosomes arise from the genotype, the total number of chromosome in mature organism cells.
A a simple method to calculate the number of gametes:
Count the number of heterozygous alleles i.e Aa Bb Cc and Dd which means 4.n = 4
Then, total number of gametes will be = [tex]2^{n}[/tex] or [tex]2^{4}[/tex] = 16Thus 16 in this condition
The 16 types of gametes are formed by this individual by permutation and combination are:
ABCD, AbCD, ABcD, ABCd,
ABcd, AbcD, ABCd, Abcd,
aBCD, aBCd, aBcd, aBcD,
abCD, abCd, abcd, abcD.
Thus, the correct answer is -
B) 1/16 of the gametes produced will be ABcd. C) The individual could make gametes that contain ABCD.Learn more about permutation and combination:

Enlist the features of cell membrane.
Answer:
It is the outermost covering of a cell that separates the contents of the cell from its external environment.
It only allows the entry and exit of some materials. It also prevents the movement of some. Therefore, it is also called a selectively permeable membrane.
Some substances like carbon dioxide and oxygen can move across the cell membrane due to the process known as diffusion.
Water also obeys the laws of diffusion. The movement of water molecules through a selectively permeable membrane is called osmosis.
