Primary succession occurs<span> in essentially lifeless areas or regions in which the soil is incapable of sustaining life as a result of such factors as lava flows, newly formed sand dunes, or rocks left from a retreating glacier. Hope this answers the question.</span>
Answer:
Evolution due to adaptation.
Explanation:
- This is very much true to the process of the natural selection and the environment does provide the species with the natural resources and gives term the power to adapt to there surroundings and the experiment given illustrate the same set of conditions and shows that how the population of the peppered/light moths takes place as the change in the color of the species increases its survival rates.
Answer:
C) Effector – Analyzes receptor output to determine if a controlled condition is correctly maintained.
Explanation:
- Effector does not analyze receptor output to determine if a controlled condition is correctly maintained. Effector just receive commands from control center and follow them.
- Control center analyze receptor output to determine if a controlled condition is correctly maintained.
Example; The temperature receptors detect the change in temperature (high temperature), they send the information to control center ( hypothalamus) to analyze the information and the control center send the command to blood vessels to dilate and active the sweat glands.
Answer:
If all humans ate only meat, will require more land to grow food crops
Explanation:
1) Currently, over 60% of the world food crops are eaten by animals. Given that food crops are generally consumed more than meat in a proportion of 8:1, if all humans ate only meat, the amount of land required to grow food crops will have to be increased by at least 400%
2) Presently, animal agriculture makes use of 70% of lands allocated to agriculture, such that increasing the livestock by an extra 400% will lead to mass deforestation in order to produce livestock feeds
3) It is more costlier to produce livestock than to produce crops, which will make the availability and allocation of land essential for the raising of livestock in order to reduce costs, thereby taking more land.
It is important that the FNR or Nadp+reductase enzyme is on the stromal side or covering of the plant's Thylakoid membrane because they participate in photosynthesis. NADPH cycling can only be achieved with light and cannot operate in the dark and stromal side provides the needed light.
