You can reduce the levels of matter pollution by reducing the amount of particulate matter produced through smoke and by reducing vehicle emissions. Reduce the amount of particulate matter produced through any types of smoke.
We reject the options a) and b) since the question says that the data supports "equally" both cases - so we have no basis for making a choice either way.
Further, in science the decisions are reached based on facts, not voting, so we also reject the answer D .
We are left with the answer C and this is also the best practice in science - when unsure, leave it as a hypothesis.
Answer:
Small intestine
Explanation:
It is in the small intestine where most food absorption occurs. Specifically, in the jejunum and the ileum. This is the site where nutrient absorption takes place too. Some water is also absorbed here, but the one mainly in charge of that is the large intestine.
Answer:
The options
a. New combinations of genes yielding genotypes of greater fitness
b. Few heterozygotes because of underdominance
c. Frequency-dependent selection, leading to fluctuations in fitness
d. Heterozygotes with greater fitness, owing to overdominance
e. A random assortment of genotypes because of genetic drift
The CORRECT ANSWER IS b.
b. Few heterozygotes because of under dominance
Explanation:
In genetics, underdominance (at times called "negative overdominance") is the opposite of overdominance.
It is the selection against the heterozygote, that leads to disruptive selection and divergent genotypes. It occurs in cases of inferior and reduced fitness (As in our case study, it is the different chromosomal fusions and inversions)
of the heterozygotic genotype to the dominant or recessive homozygotic genotype. It is unstable as it causes fixation of either allele.
Another example is the African butterfly species Pseudacraea eurytus, which makes use of Batesian mimicry to avoid predation. This species carries two alleles that gives a coloration that is alike to a different local butterfly species that is harmful to its predator. The butterflies who are heterozygous for this trait are observed to be intermediate in coloration and thus encounter an higher risk of predation and a decrease in the total fitness.
Answer:
Increases homocysteine levels
Explanation:
Homocysteine is an aminoacid that is resent in our blood already. This is mostly increased in our blood due to increased consumption of meat and other potential reasons, such as smoking.
High level of this aminoacid are linked to the development of heart diseases. This is because a high homocysteine level causes development of heart diseases along with other risks of renerl diseases.
Hope it helps!
