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 fence lizard is shown in the image below.
The main defense of a fence lizard is camouflage, which only works as long as the lizard stays still. Unfortunately, fire ants, which kill fence lizards, are not fooled by camouflage. When attacked by fire ants, some fence lizards hold perfectly still. Other fence lizards twitch to free themselves from the ants, and then they run away.
Use the above information to complete the following sentences.

How was life today similar and different to the Silurian period? ( animals, plants , organisms)
Answer:
The creatures developed in silurian period have evolved to live in sea bottoms.
Explanation:
Silurian life that is marine benthic which are bottom lying organisms belongs to the community of ecological zones that express themselves. As the gradients of temperature, pressure, and salinity. Consists of a community that is adapted to live in a darker region, used to lie in quieter environments that are in deep offshore water. These are much like the reef communities today as they do not tolerate excessive sediments. Prefer wave water that is shallow than 30 meters. These platforms are very gentle and are found over a hundred km gradients. Most of the fish represent the Silurian age and are widely distributed in marine environments. Examples of jawless fish, terrestrial fungi etc.PLZ HELP
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.

functions of ribosomes and lysosomes
Answer:
Ribosomes are responsible for making proteins
Lysosomes are responsible for removing wastes, as well as destroying a cell after it dies
Answer:
functions of ribosomes and lysosomes :-
ribosomes -
- they are many in number.
-they are not membrane bound.
-they are responsible for protein synthesis. the more the amount of protein synthesised, more the number of ribosomes.
- they are either attached to endoplasmic reticulum or they will be freely present inside the cytoplasm.
lysosomes -
- they contain digestive enzymes that break down waste materials, foreign material and cellular debris. they are capable of digesting fats,proteins, etc. along with them lysosomes also digest or damage their own cells by their own enzymes, which lead to death of the cells. this process is called as autolysis. hence, tysosomes are also called suicidal bags.
How is carbon moving between the air and found it decreasing
Answer:
Animals and plants need to get rid of carbon dioxide gas through a process called respiration. Carbon moves from fossil fuels to the atmosphere when fuels are burned.
The oceans, and other bodies of water, absorb some carbon from the atmosphere. The carbon is dissolved into the water.
