Answer:
We know the process of mitosis produces diploid cells because as a result of mitosis, identical cells are formed as the parent cell. This shows that the daughter cells are also diploid just as the parental cell.
We know the process of meiosis produces haploid cells because after fertilization, the number of chromosomes in maintained and genetic stability is achieved. The genetic stability can only be achieved if the number of chromosomes become haploid in the sex cells.
Answer:
A wetland is a distinct ecosystem that is flooded by water, either permanently or seasonally, where oxygen-free processes prevail.[1] The primary factor that distinguishes wetlands from other land forms or water bodies is the characteristic vegetation of aquatic plants,[2][3] adapted to the unique hydric soil
The answer is apical meristem.
<span>An apical meristem is a meristem tissue found at the tips of branches. When the apical meristem is active, a tree grows in height. By growing in height, leaves will be elevated and that way exposed to the sunlight so the process of photosynthesis can take place.</span>
Your correct answer would be A. Nervous system
The food chain and food web are used to transfer energy. Plants, who are the primary energy providers in the ecosystem, use their chloroplasts to collect sunlight, which is then partially converted into chemical energy during photosynthesis.
a)
- When herbivores eat (are the primary consumers of) plants as food, this energy is transferred to the primary consumers in the food chain.
- This energy is stored in various organic products in plants. Then, the chemical energy contained in plant products is converted into kinetic energy, degrading the energy by turning it into heat. The secondary consumers come next.
- Further deterioration will occur when these herbivores are consumed by secondary consumers.
- Finally, energy will once more be destroyed when tertiary consumers eat the carnivores. As a result, the energy flow is only in one direction i.e., unidirectional.
b)
- Additionally, the energy flow in a food chain adheres to the 10% law.
- This law states that only 10% of energy is transferred from one trophic level to the next, with the remaining 90% being lost during the digestion process of the organism itself.
c)
- There are typically fewer organisms at the top of an energy pyramid because It has the least quantity of energy, the top level of an energy pyramid has the fewest organisms.
- Most ecosystems only have four trophic levels because there is eventually insufficient energy to maintain further trophic levels.
d)
- For instance, let us assume that a plant at the producer level produces 1000 Kcal of energy.
- When a primary producer eats this plant, it will only get 10% of the energy produced by the plant i.e., 1000/10 = 100 Kcal. the rest 90% will be used up by the plant itself for its metabolism.
- Further when a secondary consumer eats the primary consumer, it will only get 10% of the energy produced by the plant i.e., 100/10 = 10 Kcal.
- Lastly, as the tertiary consumer eats the secondary consumer, it will only get 10/10 = 1kcal.
