Movement of chromosome segment to a non-homologous chromosome. This type of chromosomal mutation occurs when one chromosome swaps genetic information with a different chromosome (this is NOT Crossing Over). O Inversion O Duplication O Deletion O Translocation
Answers
Answer:
The correct answer is ''Translocation.''
Explanation:
Translocation is a chromosomal abnormality that is due to a change in position of a chromosomal segment to another non-homologous chromosome of the same nucleus or to another part of it. It is produced by the exchange of segments between two chromosomes without loss of genetic material is called reciprocal or balanced translocation, when it gives rise to monocentric chromosomes.Translocations can be detected cytologically because the structural heterozygote forms a quadrivalent (4-chromosome association) in meiotic prophase. Sometimes they can also be detected by changes in the size of the chromosomes if the exchanged segments are of different lengths.

Answers
Answer:
amino acids

Explanation:
Excretion refers to the removal of waste products that is produced from amino acids metabolism.
Carbon dioxide is formed in living organisms in the process of both aerobic respiration and anaerobic respiration and can be removed from the body through lungs.
Urea is produced in the liver and then the blood is to be sent to the kidney and which is excreted from the body.
Urea is compounds of nitrogen which is formed from amino acids that contains toxic substances which the body does not need.
The leaves of plants have many specialized structures. Which statement explains the importance of the stomata and guard cells for the plant?
o They protect the plant from pests
o They are involved in plant reproduction
They work together to regulate water loss and gas exchange.
o They regulate the amount of water that enters the plant for cellular respiration
Answers
Answer:
They work together to regulate water loss and gas exchange.
They work together to regulate the loss of water and exchange of gases.
Stomata and guard cellsThe tiny pores or openings in plant tissue, which allow for the exchange of gases are known as stomata.
The unique cells, which surround stomata and work to close and open the stomatal pores are known as guard cells.
Both these helps a plant to take in carbon dioxide at the time of photosynthesis and also assist in reducing the loss of water by getting closed when conditions are dry and hot.
Thus, stomata and guard cells work together to regulate the loss of water and gas exchange.

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.
Answers
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.
