Explanation:

As your HR increases during exercise, your muscles, heart, pulmonary system needs to deliver more O2 to those parts of the body, for proper function. without this your muscles will rely on stored fat for energy, which causes the muscle tissue to excrete lactic acid into the bloodstream. lactic acid is known to cause sepsis and also shock. sodium, potassium, and electrolytes are needed to retain fluids in the body more efficiently.

  • Answer. While doing exercise the more the intensity of the exercise is the more the heart rate. While heart rate increases it pumps more blood which result in more blood circulation in the body.  Explanation:  This changes occur mainly due to body mechanism which needs more energy to burn . While fast breathing we inhale more oxygen which is used in producing more energy.  I hope this helps you

ArbitrLikvidat [17]

Answer:

The new cells are the same as the previous ones, since they are the result of the mitosis process.

Explanation:

When we cut our skin, our brain sends information to millions of cells to take action and prevent this cut from putting us in danger. At that moment, the blood cells begin their work, supplying enough oxygen to stop possible bleeding and start the healing process. Then another group of cells swap out possible bacteria that may be trying to get into the wound. Last but not least, skin cells enter cell division and undergo mitosis, to generate new cells and create a new skin layer.

New cells are the same as old cells, as they are the result of mitosis. Mitosis is the process of cell division where one cell gives rise to two cells exactly the same as it.

Environmental factors can influence natural selection because they can increase or decrease
olchik [2.2K]

Answer:

Environmental factors can influence natural selection because they can increase or decrease the amount of genetic variation in a population.

Explanation:

Natural selection is a process that involves the survival of species through changes in the expression of their genes, making possible the process of adaptation to environmental changes. It is one of the explanations for the biological evolution of species.

The second premise, necessary for natural selection to be possible, implies the existence of a variability (genetics) of traits among individuals in a population.

The other premises of natural selection are the faculty of traits to be inheritable and that genetic variability should lead to reproductive success and survival.

  • <em>The other options are not related to the process of natural selection, since it is not possible for natural selection to increase or decrease the number of chromosomes, in addition to the fact that genetic variability must be observed in a population, not in a single individual, to be considered natural selection </em>
