Condensation → Nuclear membrane disassembly → Arrangement at equator → Centromere division → Segregation → Telophase is the correct sequence of events during mitosis.
During prophase, the chromosomes condense, the nucleolus disappears, and the nuclear envelope breaks down. The chromosomes align at the metaphase plate, the centromeres divide and during telophase, the chromosomes segregate and move to opposite ends of the cell and two nuclei are formed.Prophase is the first phase of mitosis. The chromosomes in the nucleus start to condense and become visible at this point.Prometaphase is the following phase. The nuclear envelope disintegrates at this time, and the chromosomes cling to the spindle fibres.Metaphase is the third phase. The chromosomes align on the metaphase plate in the centre of the cell during this time.Anaphase is the fourth phase of mitosis. The spindle fibres force the chromosomes apart at this stage, causing them to migrate to the opposing ends of the cell.Telophase is the final phase. Chromosomes have now reached the cell's poles, and the cell is beginning to divide into two daughter cells.To know more about mitosis check the below link:

If mitosis makes somatic (body) cells, what does meiosis make?
A. Sex cells
B. Heart cells
C. Nerve cells
D. Body cells
Meiosis creates sex cells, just as mitosis creates somatic (body) cells.
In living things, there are two different types of cell division: meiosis and mitosis. Meiosis produces four genetically distinct cells, whereas mitosis produces two genetically identical cells from a parent cell.
Somatic cells, such as liver cells, skin cells, etc., are body cells that do not participate in reproduction. Mitosis is the process through which somatic cells divide. Meiosis is the process by which sex cells, or gametes, are created because they are involved in reproduction. Meiosis contributes to sexual reproduction's genetic diversity.

What Is Genetic Diversity and Why Does it Matter?
Diversity refers to having a variety of different things, and Genetic refers to features that are related to traits transferred from parent to offspring. Genetic diversity describes the variety of unique hereditary features found in a species.
There would be a large number of individuals with a diverse range of attributes in a species with great genetic diversity. A population must have genetic diversity in order to adapt to ever-changing conditions. The wild population's capacity to adjust to changes will be lowered if a strain with high selection pressure and little diversity—like fish populations raised for aquaculture—is introduced into the population. It is crucial for species to have genetic diversity since it increases their chances of surviving. However, when populations become smaller and more isolated, genetic diversity can be lost, which reduces a species' capacity for adaptation and survival. It follows that populations with more genetic diversity are thought to have greater adaptive potential due to larger levels of standing genetic variation, making them more resilient to changing environmental conditions and hence more suitable for conservation efforts.

Based upon your knowledge of the mechanisms mediating skeletal muscle contraction,the force generated and duration of contraction would be greater than control.
What is contraction?
Actin and myosin filament interaction, which causes their relative movement to one another, causes muscle contraction as a result. Myosin's association with actin filaments provides the chemical underpinning for this interaction, enabling it to operate as a motor to promote filament sliding.
Thick myosin filaments and thin actin filaments glide past one another to cause muscle contraction. The broad consensus is that cross-bridges that protrude from myosin filaments and engage in periodic interactions with actin filaments when ATP is hydrolyzed are responsible for driving this process.

A student designed an experiment to investigate a claim that athletes would have lower heart rates than nonathletes during exercise. After the students classified themselves as an athlete or a nonathlete, their resting pulses were determined. Then all the students performed the same exercise for four minutes and their heart rates were determined by recording the pulse rate in beats per minute. The students continued to measure their pulse rates for an additional four minutes. The average heart rate per minute for each group was determined. The data were recorded, as shown on the table below.
After activity, the heart rates of the athletic students reverted to resting pulse in four minutes.
Physical activity is connected with haemodynamic alterations and modifies the loading circumstances of the heart. In dynamic exercise the emphasis is on movement with no or limited production of force. The key haemodynamic aspects are increases in heart rate and stroke volume, the two components of cardiac output. Although the overall effect is a mild to moderate increase in blood pressure, systemic vascular resistance declines. Volume exerts the heaviest burden on the heart. In static workout force is created with no or limited movement. The haemodynamic repercussions involve a small elevation of cardiac output, produced by the increase of heart rate, and a more dramatic rise of blood pressure, resulting in a pressure load on the heart.

Modern bananas originated from a cross between a tetraploid banana species and a diploid banana species. The product of this cross was the triploid Cavendish banana strain, a sterile hybrid that is only grown asexually. Recently, the Panama fungus has been observed more frequently parasitizing the Cavendish banana, and scientists claim that this type of banana is on the brink of extinction.
Which of the following provides the best explanation of the scientists’ claim regarding the threat to the Cavendish banana?
The triploid genome of the Cavendish banana makes it susceptible to the negative impact of recessive alleles.
Having three of each chromosome interferes with normal function of the cells and increases the likelihood of contracting a disease.
The lack of genetic diversity of the Cavendish banana decreases the chance that a variation exists in the population that is immune to the fungus.
Asexual reproduction increases the mutation rate during replication, resulting in a greater chance that the offspring have a dysfunctional immune system.
The best explanation is that lack of genetic diversity of the Cavendish banana decreases the chance that a variation exists in the population that is immune to the fungus.
Loss of genetic range will increase the chance of extinction of a populace thru inbreeding depression. In addition, the range of deleterious genetic variations, which would possibly acquire in a small populace thru genetic drift, also can make the populace vulnerable.Inbreeding, genetic drift, constrained gene flow, and small populace length all make a contribution to a discount in genetic range.
Fragmented and threatened populations are commonly uncovered to those conditions, that is in all likelihood to boom their chance of extinction.
