Help, please try to answer all :) Overdue

kolezko [41]

Answer:

1. C

2. I

3. B

4. I

5. A

Explanation:

1. Nonrenewable resources include oil, natural gas, coal, and nuclear energy.

2. Nonrenewable resources cannot be readily replaced at the speed with which they are being consumed.

3. Renewable sources include biomass energy (such as ethanol), hydropower, geothermal power, wind energy, and solar energy. Biomass refers to organic material from plants or animals, etc.

4. Because they take a very long time to form. They are not replaceable.

5. Corn can be used for ethanol fuel, and a new crop of corn can be grown and harvested each year. Corn is a renewable resource. Also, renewable resources cannot be replaced in our lifetime.

Both intrasexual and intersexual selection usually cause changes in phenotypes for males and little changes in female phenotypes

saveliy_v [14]

The question is incomplete. Please read below to find the missing content.

Selection is usually strongest in the male of the species. D) because sperm are small and plentiful, while eggs are large and energy-rich.

Phenotype refers back to the observable traits of an organism as a multifactorial effect of genetic trends and environmental influences. The organism phenotype includes its morphological, biochemical, physiological, and behavioral residences.

A person's genotype is their specific collection of DNA. extra especially, this term is used to refer to the two alleles a person has inherited for a selected gene. Phenotype is the detectable expression of this genotype – a patient's clinical presentation.

The sum of an organism's observable traits is its phenotype. A key difference between phenotype and genotype is that, even as genotype is inherited from an organism's parents, the phenotype isn't.

Both intrasexual and intersexual selection usually cause changes in phenotypes for males and little changes in female phenotypes. Why is sexual selection usually strongest in the male of the species?

a. Males are naturally more aggressive

b. Males have a smaller genetic component than females due to fewer X chromosomes

c. Males do not pass on their mitochondria and therefore have more invested in each individual mating event

d. Because sperm are small and plentiful, while eggs are large and energy-rich.

Two brothers have X‑linked red–green colorblind vision, and their parents have normal color vision. The first brother's karyotyp

zhenek [66]

Answer:

The answer is mother in meiosis II

Explanation:

nondisjunction can be defined as the failure of the segregation of the child chromosomes in meiosis I and meiosis II resulting in gametogenes. This results in abnormal gametes with some chromosomal imbalance being formed and subsequent fertilization of these gametes results in a generation of abnormal individuals.

According to exercise, red-green color blindness follows an X-linked recessive pattern and the phenotype is only expressed. the father cannot bring the possibility of color blindness to his children, and the nondisjunction, defined earlier, cannot occur in either meiosis I or meiosis II. As a conclusion we can say that it may have a place in meiosis I or meiosis II corresponding to the mother and although the mother's condition may be normal, the first child would be compromised with color blindness, therefore, the mother is the carrier.
