Darwin focused most on adaptations when developing his ideas about natural selection (Option D).

Evolutionary adaptive features are different phenotypic traits in organisms that confer an advantage in reproduction and or survival for a particular environment in which these organisms live. Thus the process of natural selection selects them to form the next generation.

Therefore, with this data, we can see that evolutionary adaptive features are separated by natural selection in order to produce a new generation of individuals associated with these phenotypic traits.

VO2 max is increased, plasma volume expansion is stimulated, and body fat mass is decreased through cardiovascular endurance training.

The ability to undertake dynamic, large-muscle exercises for a lengthy amount of time at a moderate to high intensity is known as cardiovascular endurance (typically over 20 to 30 minutes). It gauges how well your body can expel carbon dioxide and deliver oxygen-rich blood to your organs. As a result, cardiovascular endurance serves as a reliable predictor of the health of the heart, lungs, and muscles. You can exercise and work out intensely longer if your cardiovascular endurance is higher than that of someone with lower endurance.

Measurements of cardiovascular endurance look at how much oxygen your body consumes during vigorous exercise. METs and VO2 Max are two metrics that are used to gauge the condition of your cardiorespiratory system.

Cell-cycle checkpoints prevent the transmission of genetic errors to daughter cells. There exist three major cell-cycle checkpoints; the G1/S checkpoint, the G2/M checkpoint, and the spindle assembly checkpoint (SAC).

The vast amount of DNA contained within the chromosomes must be precisely duplicated before being precisely separated into two daughter cells that are genetically identical. This is the most fundamental task of the cell cycle.

Walther Flemming was the first to depict the various steps in the cell cycle that lead to cell division in 1882 after creating techniques to stain cells that revealed subcellular structures. To divide the genetic material in a cell, spindle fibers create a protein structure. When a parental cell undergoes mitosis or meiosis, the spindle is required to divide the chromosomes into two daughter cells in an equal number. The spindle fibers that form the mitotic spindle are known as such during mitosis.

Answer: B

Explanation:

Mitochondria is a cell organelle  that makes ATP needed for cellular energy.

The majority of the chemical energy required to drive a cell's metabolic operations is produced by mitochondria, which are membrane-bound cell organelles (mitochondrion, singular). Adenosine triphosphate, a tiny molecule, serves as a storage container for the chemical energy generated by the mitochondria (ATP). Small chromosomes found in mitochondria are found there. In most cases, mitochondria and consequently mitochondrial DNA are exclusively passed down from the mother.

Although their cross-section is typically between 0.75 and 3 m2, mitochondria differ greatly in size and structure. They are barely noticeable unless they are deliberately discoloured. Mitochondria provide a variety of functions in addition to producing cellular energy, including signaling, cellular differentiation, and cell death, as well as regulating the cell cycle and cell proliferation. These cellular processes are in turn temporally coordinated with mitochondrial biogenesis.

Hence, mitochondria is considered as powerhouse of cell.

Monitoring heart rate is important because working your heart at maximum capacity or too high actually limits the amount of oxygen your body can get. Your heart rate can be monitored by using a heart monitor or monitoring your pulse during exercise.

Exercise causes your heart rate to increase because your body needs more oxygen. After traveling to the lungs to receive oxygen, the heart pushes blood toward the rest of the body, including the muscles. Regular exercisers' hearts adjust to deliver the required oxygen, and while their heart rates rise during exercise, they quickly return to normal afterward. Your heart rate may spike if you suddenly try a high-intensity activity if you don't usually exercise.

In one minute, your heart can beat as swiftly as it can at its maximal rate.

You can get your maximum heart rate by subtraction from 220 of your age. Even while your heart rate may reach its highest during exercise, continuing at such high levels can wear you out. If your heart rate suddenly spikes because you are not used to regular exercise, it will take longer for your heart to settle down to its normal, resting activity. You may have increased perspiration as a result of the heart muscle working harder and taking longer to return to normal.

Autosomal recessive inheritance refers to the way in which some genetic changes, or rare diseases, are passed down from parents to their offspring.

The specific chromosomes impacted by autosomal recessive inheritance are autosomal. This indicates that one of the first 22 non-sex chromosomes contains the gene mutation that results in an autosomal recessive uncommon disease or ailment. The 46 chromosomes found in 23 pairs make up the body's cells. One from the mother and one from the father make up each pair of genes.

When a person receives two mutated genes from each of their parents, this is known as autosomal recessive inheritance. The same gene has mutations in both copies. Both parents must have the gene mutation for this to occur. They are unlikely to have any disorder symptoms because they are carriers.

There is no guarantee that the offspring of parents who carry an autosomal recessive gene mutation will suffer from a rare disease.

Their offspring will have a 25% chance of being born with two normal genes (i.e., without any mutations), a 25% chance of inheriting both recessive gene mutations (i.e., the child will be affected by an autosomal recessive disorder), and a 50% chance of having a child who is a carrier of the same genetic mutation as their parents but does not exhibit any symptoms of a rare disorder.
