Answer:

Effects of exercise on breathing

During exercise there is an increase in physical activity and muscle cells respire more than they do when the body is at rest.

The heart rate increases during exercise. The rate and depth of breathing increases - this makes sure that more oxygen is absorbed into the blood, and more carbon dioxide is removed from it.

The rate of breathing can be measured by counting the number of breaths in one minute. The depth of breathing can be measured using a spirometer (a device that measures the volume of air inhaled and exhaled).

To investigate the effects of exercise on breathing, record the rate of breathing for a few minutes when the person is at rest. After they do some exercise, record their rate of breathing every minute until it returns to the normal resting value.

ou find some rather strange plants in your backyard. They consist only of thin, pale yellow stems that are wrapped around other

deff fn [24]

Answer:

Parasitic

Explanation:

The plants that are described are typical example of parasitic plants. These types of plants have a parasitic relationship with the other plants, at least with the ones that they can use. In order for them to grow, survive, and prosper, these plants need a host plant. They attach to the host plant's steam with their miniature claw like organs, and use them for support to grow upwards, but also to extract nutrients from the host plant. While this leads to to parasitic plant's survival and prospering, the host plant is suffering, and gradually the parasitic plant will suck every nutrient out of the host plant and kill it. Without a host plant, these plants would find it extremely hard to survive, and the chances are very high that they will die because they are not well suited to get nutrient on their own.

The desert fennec is a small fox that lives in the sahara desert. it has long limbs and long ears. compared to the desert fennec

Vanyuwa [196]

C<span>ompared to the desert fennec, you might expect the arctic fox to have shorter ears.
Given that the desert fennec fox lives in the desert, where it is quite dry and hot, and the arctic fox lives in a place where it is extremely cold, by analogy, if the first fox has long ears, the second one will have shorter ears. Because the locations they live in are quite different, their ears are going to be each other's opposites.

sveta [45]

<h2>Answer is option "A"</h2>

Explanation:

The standards of nucleocytoplasmic transport, and afterward portray the various systems utilized by infections to convey their genomes into the host core. A portion of the developing instruments include:
An atomic section during mitosis, when the atomic envelope is dismantled
Viral genome discharge in the cytoplasm followed by a passage of the genome through the atomic pore complex (NPC)
Capsid docking at the cytoplasmic side of the NPC, trailed by genome discharge
Atomic section of unblemished capsids through the NPC trailed by genome discharge
Atomic passage by means of infection initiated disturbance of the atomic envelope. Which system a specific infection utilizes relies upon the size and structure of the infection just as the cell signs utilized by the infection to trigger capsid dismantling and genome discharge
Hence, the right answer is option "A"
