Answer:

The correct answer is "low concentration of oxygen".

Explanation:

One of the key characteristic of aquatic dead zones is its low concentration of oxygen. Aquatic dead zones are classified into this category for being hypoxic, condition that do not support the growth of most marine life. Most aquatic dead zones are in these conditions because of a high content of nutrient pollution caused by human activities.

Minchanka [31]

Answer: Yes

Explanation:

Carrying capacity can be defined as the total number of members of the population of a species that an ecosystem can sustain in terms of providing resources in the form of food, shelter and others. When the resources are available in surplus then the population of a species increases exponentially but declines when resources become scarce. The human population is increasing tremendously all over the world this is supported by the resources like food, water, fossil fuels, air, minerals, and others. But some of these resources are decreasing due to overuse and may not be available in future to sustain the future generation.

If there are probability of 50% of producing male gamete then what would be the probability of producing transgender. When fathe
Vaselesa [24]

The probability of producing a transgender = None ( D ) when the father is gay

The probability of producing male gamete is not affected by the sexual orientation of the Father because the production of the male gamete is carried by the spermatogonia found in the testes of a male. and every male specie regardless of your sexual orientation have testicles where the spermatogonia undergoes mitotic divisions to produce the male gametes.

Hence the probability of producing a transgender given that the father is gay is non-existent i.e.0%

Rina8888 [55]

The question is incomplete. The complete question is:

Question: A gene for corn has two alleles, one for yellow kernels and one for white kernels. Cross pollination of yellow corn and white corn results in ears of corn that have an approximately even mix of yellow and white kernels. Which term best describes the relationship between the two alleles?

a) Incomplete dominance

b) Genetic recombination

c) Chimerism

d) Codominance

Answer:

d) codominance

Explanation:

Codominance is a pattern of inheritance when none of the alleles of a gene is able to mask the expression of the other allele of the same gene. When the two alleles are present together in a heterozygous genotype, both are expressed and the phenotype of the heterozygote is different from both the pure breeding parents. In the given example, cross-pollination of yellow corn and white corn results in the ears of corn that have an approximately even mix of yellow and white kernels. This means that the heterozygote expresses both the allele for the corn color. Therefore, it represents codominance.
