Answer:
Cell Nucleus
Explanation:
The nucleus is perhaps the most important structure inside animal and plant cells. It is the main control center for the cell and acts kind of like the cell's brain.
Do mutations in body cells contribute to genetic variation?(1 point)
A) No, the causes of body cell mutations are outside the body and cannot alter DNA.
B) Yes, the mutations can be passed on to offspring and contribute to variation in the population.
C) Yes, these body cell mutations lead to mutations in the gametes.
D) No, the mutations cannot be passed to offspring and only affect the individual.
A mutation is the alteration of the genetic sequence of an organism, which can either be inherited or cannot be inherited. The mutation when transmitted to the offspring leads to genetic variation.
The correct answer is:
Option B. Yes, the mutations can be passed on to offspring and contribute to variation in the population.
Mutation is the change in the genetic sequence of the organism, which can be caused due to environmental factors and can be inherited.
The mutations can lead to genetic disorders, chromosomal disorders, or any other conditions. The mutations like a disease or adaptation that can be passed onto the offspring can result in genetic variation.
The mutation leads to genetic diversity, as the mutation is also the first step towards evolution. The organisms better suited to the environment will survive more and adapt more. These changes in the organisms will be inherited by the offspring leading to genetic variation.
Therefore Option B is correct.

Make a claim about the types of wastes that the excretory system removes.
Answer:
Explanation:
Urea is the cellular waste product that the kidneys remove from the blood.Kidneys are the two bean shaped organs that has several functions to keep the body healthy. It not only removes urea from the blood, but also helps in the formation of urine and maintaining the fluid level of the body. The two kidneys are placed on the two sides of the spinal cord. The blood enters the kidney through the renal artery. The nephron within the kidneys mainly take out the waste products and the excess water from the blood and purifies it.If the kidneys of a person fail to work properly then it becomes important to perform dialysis for taking out the waste materials from the blood.

A deletion mutation causes three consecutive nucleotides to be removed from the
DNA code.
Which option describes the possible effect of this mutation?
Select one:
Three amino acids may not be present. The rest of the amino acids would be in the protein
in the correct order.
Five amino acids may not be present. The rest of the amino acids would be in the protein
in the correct order.
Two amino acids may not be present. The rest of the amino acids would be in the protein
in the correct order.
One amino acid may not be present. The rest of the amino acids would be in the protein in
the correct order.
The deletion mutation will cause one amino acid to be absent while coding for other protein in the correct order. Therefore, option (D) is correct.
What is deletion mutation?By eliminating at least one nucleotide from a gene, a deletion modifies the DNA sequence. Larger deletions can eliminate a whole gene or a number of nearby genes, while smaller deletions just delete one or a few nucleotides from a gene. The function of the affected protein or proteins may change as a result of the deleted DNA.
An insertion or deletion, often known as a frameshift mutation, can alter every codon in a certain genetic sequence by upending the three by three codon structure as a whole. As an illustration, consider the following code, which stands for the amino acids aspartate, aspartate, serine, alanine, and arginine: GAU GAC UCC GCU AGG.
