Answer:b
Explanation:
Heterogeneous mixture because it is not chemically bound together
Answer:
Tundra
Explanation:
Permafrost is a layer just beneath the surface of the ground that never thaws.
The answer is D, for when one tropic level is eaten by the tropic level above it, the tropic level is supporting the higher one. I. E. Rabbits are supported by the grass because rabbits eat the grass. Also, the grass population would be larger than rabbits, the rabbits larger than snakes, so on and so forth, so B is ruled out. B states that each population is larger than the one BEFORE it, but there is no way there would be more rabbits than grass. Also, there are both herbivores and carnivores in the food chain, so A and C are out. The best answer is D.
The heart would be one of the most affected organs if the mitochondria do not produce enough energy, since this organ requires a lot of energy, so any supply failure leads to heart failure and contraction failure.
<h3>What are mitochondria?</h3>
They are the cellular structures responsible for supplying most of the energy necessary for cellular activity.
<h3>Characteristics of mitochondria</h3>
- They produce energy from the metabolism of organic fuels such as sugars, lipids (fatty acids) and amino acids.
- Insufficient energy production by the mitochondria causes dilated cardiomyopathy, where the heart undergoes significant dilation and loses the force of contraction.
Therefore, we can conclude that a defect in a mitochondrial process involved in energy production would affect heart cells causing dilated cardiomyopathy, heart failure.
