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
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.
What type of mutation is the example below?
Original DNA: T T T G G G A C T A T C C A T A T C
Mutated DNA: T T T A G C C T A G G G A C T A T C C A T A T C
A: point mutation
B: Frameshift Mutation
C: deletion
D: Insertion
E: Inversion
Answer:
Insertion

Answer:
The population of peppered moths thrived, because they camouflaged with the bark of the trees, thereby they were not easily seen by predators. Black moths were easily seen by predators and they were eaten as a result. Because the black moths did not survive, they were unable to reproduce offspring with those traits. However, peppered moths were able to reproduce offspring that were also peppered. During the industrial revolution, the colour of the bark darkened. This meant the peppered moths were easily seen by predators, so they were eaten. Black moths camouflaged with the bark, so now they weren't easily seen by predators. Now that the black moths survived, they could reproduce more black moths. But peppered moths weren't able to reproduce more peppered moths because most didn't survive. This is an example of how an abiotic factor, such as bark can affect a population of a species. Because the bark influenced the survival of the moths, some moths with the desirable traits survived, and others with the undesirable traits died.

Each of your cells has a set of chromosomes, including
autosomes and sex chromosomes. Explain the main
differences between these two types of chromosomes.
Answer:
in the 46 chromosomes in our body, the autosomes are the first 22 homologous pairs of chromosomes that do not influence the sex of an individual, while sex chromosomes are the 23rd pair of chromosomes that determine the sex of an individual

Excretion is defined as the removal of material and the waste products of metabolism.
Carbon dioxide is formed in humans during the process of .
Urea is produced in the and is excreted in the .
Urea is formed from that the body does not need.
Answer:
amino acids
anaerobic respiration
aerobic respiration
lungs
liver
kidneys
nitrogen
toxic
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
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.

When glucose is being formed during the Calvin Cycle, which
molecule/substance provides the carbon in order to make the glucose?
rubisco
water

ATP
Answer:
Rubisco.
Explanation:
Las reacciones del ciclo de Calvin añaden carbono (del dióxido de carbono en la atmósfera) a una molécula sencilla de cinco carbonos llamada RuBP. Estas reacciones usan la energía química de la NADPH y del ATP que se producen en las reacciones luminosas. El producto final del ciclo de Calvin es la glucosa.

Explanation:
Blue flower is dominant to yellow flower. Tall plant is dominant to short. Cross BbTt * BbTt. What precenetage of the offsprings are expected to be heterozygous for both traits?
Answer:
The correct answer would be - 25%.
Explanation:
It is given that the Blue flower is dominant over the yellow flower which means Blue is represented by allele B here and allele b for yellow and Bb is a heterozygous case with a blue phenotypic character. Similarly, the Tall plant is dominant over short and represented by T and t respectively.
BbTt is a heterozygous condition and a cross with itself will produce :
Gametes: BT Bt bT and bt
BT Bt bT bt
BT BBTT BBTt BbTT BbTt
Bt BBTt BBtt BbTt Bbtt
bT BbTT BbTt bbTT bbTt
bt BbTt Bbtt bbTt bbtt
Here 4 out of 16 offspring are heterozygous for both traits represented by bold alphabets. Therefore the correct answer is 25%
