C. in the nucleus, because this is where the DNA is located.
<h2>Answer:
</h2>
Option a) The removal of the trees and grass during construction could result in erosion of topsoil.
<h2>Explanation:
</h2>
- Plants play a vital role in an ecosystem such as they produce oxygen, food, plays an important role in hydrological cycle(water cycle) etc.
- Deforestation in simple words, is the cutting down of forests for human use such as to clear land for construction, for fuel, for making furniture etc.
- Deforestation is one of the major reason for Soil erosion.
- Soil erosion is a natural process, but it get accelerated by deforestation.
- Plants are a natural barrier to slowdown soil erosion by slowing down the water current, as running water can also be a reason for soil erosion. Roots of the plants binds with the soil tightly and prevent it from washing away by water or taken away by air. Plant growth in less nutritious soil(Lower layers of soil) is very difficult(as the top layer contains maximum nutrients).
Result: Deforestation in forests and marsh play a major role in erosion of the top layer of the soil.
Sun/inorganic compounds
autotrophs (producers)
heterotrophs (consumers)
The sun is the main sources of energy. The energy in the form of sunlight is converted into a form of energy that organisms can used. Plants converts sunlight into their food through photosynthesis. Plants will be considered as the producers. They will be eaten by herbivores or the heterotrophs/consumers. Energy can now be transferred to the consumers because they cannot utilize sunlight to form their own food.
Answer: The correct answer for the blank is-
A) mitosis; meiosis
Mitosis is a type of cell division in which a parent cell produces two daughter cells with equal number of chromosomes as that of parent cell. It is essential in repair of damaged tissue and growth of living organisms. This is because body cells produce additional body cells with same genetic material.
Meiosis is another type of cell division that is specific to the sexually reproducing organisms. It is a reductional division as the diploid parent cell produces four haploid, reproductive cells ( called gametes such as eggs and sperms). This means that gamete formation in sexually reproducing organisms occurs through meiosis.
Thus, option A) is the right answer.
Answer:
The diatom cells are not interconnected and are very similar to diatoms that are living unicellularly. The Spirogyra cells are the building blocks of the filaments.
