Answer:
d
Explanation:
<em>The correct answer would be increasing heart rate to compensate for low cardiac output.</em>
The negative feedback loop is the mechanism that is utilized in the maintenance of homeostasis. They work by opposing the processes that bring about a deviation away from setpoints, that is, the normal range of operation of physiological processes in the body.
<u>For example, when the heart rate goes below the setpoint, the negative feedback loop swings into action through the sensor, the control center, and the effector to return the heart rate to the normal operating range.</u>
Correct option: d
C
by using your cells to make copies of themselves
Unfortunately this question is incomplete. Glycolysis occurs in the cytoplasm of prokaryotic cells and in the cytosol of eukaryotic cells. Cytosol is a liquid composed mainly of water with some ions and proteins that comprises the majority of the volume of a cell, and it holds the cell organelles. The cytosol is the site of most of the metabolic activity in the cell.
The correct answer is D. Pioneer species
Explanation:
In biology, the term "pioneer species" refer to the first species that colonize new environments or environments in which there is no biodiversity for example lands that have been affected by fire, lava, etc. These species are in most cases plants or small organism that are resistant and able to adapt to the harsh conditions of new land. Additionally, this concept differs from keystone and foundation species because these two concepts describe species that have an important role in the ecosystem rather than those that first live on new land. Therefore, the first species to live on new land are the pioneer species.
large surface area,
high CO2 concentration
High blood diffusion (from high to low concentration)
Thin walls adjusted for gaseous exchange.
