Answer: fossil records
Explanation: there where the same species on different continent's
False. It is not a natural process. Humans choose the desirable features of a particular dog and selectively breed it. These dogs have not adapted to the environment. This selection is mostly based on cosmetic reasons or other desirable features. These dogs prob wouldn't be able to survive in the wild
Answer:
Hope this helps!
Explanation:
We as a species should focus on both because Technology and bees are both neccesary components to our daily healthy life.
Answer:
Option (3).
Explanation:
The homeostasis of the body is maintained by the feed back loop system. Two main types of the feedback loop system of the body are positive feedback system and negative feedback system.
Positive feedback system may be defined as the feedback in which the final product increases the output of that product. Pepsinogen is an zymogen that helps in the activation of pepsin enzyme. This enzyme helps in the digestion of protein. The digestion of pepsinogen by pepsin result in the more production of pepsin.
Thus, the correct answer is option (3).
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.
