Answer:
- Human Health: Human health is a result of environmental degradation. Areas exposed to toxic air pollutants can cause respiratory problems like pneumonia and asthma. Millions of people are known to have died due to the indirect effects of air pollution.
- Loss of Biodiversity: Deforestation, global warming, overpopulation, and pollution are a few of the major causes of loss of biodiversity.
- Tourim Industry: The deterioration of the environment can be a huge setback for the tourism industry that relies on tourists for their daily livelihood. Environmental damage in the form of loss of green cover, loss of biodiversity, huge landfills, increased air, and water pollution can be a big turn off for most of the tourists.
Answer:
Yes frontal lobe is the correct answer.
The correct answers to these questions are the following:
1) By analyzing enclosures with different colors on the ground that can either favour or hinder the success of the populations.
2) Independent variable: number of generations.
3) Null hypothesis: different colors have no effect on the fitness of the populations.
4) It is a consequence of directional selection. Directional selection is a type of natural selection where the frequency of a trait is modified to benefit a phenotype in response to a change in the environmental conditions.
Explanation:
C is the correct answer i.e. splitting of a nucleus
Answer:
a) False.
b) True.
c) False.
d) True.
e) False.
f) True
g) True.
Explanation:
a) The main characteristic of homologous chromosomes is that they have an equal size. There is a difference in size on both chromosomes.
b) In number one, two chromosomes are homologous. In number two also two chromosomes are homologous. On the other hand, the chromosomes at number one and two are different. Each chromosome has two sister chromatids.
c) A DNA molecule has a double helix, that is, two chains. When a DNA chain is broken and a chromatide has a DNA chain, then two chromatids make up a chromosome and a DNA chain, in this way there are eight dsDNA molecules
d) If each chromosome contains a centromere, therefore, there are four centromeres on all four chromosomes.
e) If a chromosome contains four telomeres, therefore there will be sixteen telomeres.
f) The function of cohesin is to regulate the separation of chromatids in the cell division process. When DNA replication is complete, the DNA compacts and condenses to form mitotic chromosomes.
g) The CENPA protein is encoded by the CENPA gene.
