Explanation:
Carrying capacity refers to the maximum number of individuals of a certain species an environment can maintain in the long-term.
Factors that will determine carrying capacity include amount of water available in the environment, geographic size of environment, energy sources available, and so forth.
The image below shows the general idea of carrying capacity and population size:
The reality is often not so simple, as populations can overshoot their carrying capacity. When this happens, it takes some time for the population numbers to decrease. Thus, graphs more realistically resemble the one below:
Over time and with no disturbances, the population will generally max out at the carrying capacity. It is also important to remember that environments may not be unchanging, especially in certain time scales. For example, an increase in rainfall one year may mean that there is far more standing water available in the environment. Thus, mosquito populations will temporarily increase as the carrying capacity for them allows for higher numbers.
<span>Not only does topsoil erosion lead to loss of soil fertility, it can also cause water pollution. Water pollution is a result of the downpour of the fertilizer chemicals to the water contaminating the water in terms of sulfur content, halogen content, and other possible metals.</span>
Answer:
The relative size of the crest height and width of offspring raised in the tank without chemical cues is lower as compared to the parent Daphnia.
Explanation:
The size of the crest of Daphnia is directly related to the chemical cues secreted by the Notonecta. If the water has Notonecta , the size of the crest of Daphnia is increases because the crest is sensitive with the release of the chemical cues of Notonecta. So if the water has no chemical cues, the size of the crest height and width of offspring is lower as compared to the parent Daphnia.

In complete dominance, the dominant alleles hide the expression of the recessive allele. Option C. All of the offspring will exhibit the
dominant trait.
<h3>
What is complete dominance?</h3>
Complete dominance occurs when one of the alleles -the dominant one- completely hides the expression of the other allele -the recessive one- in heterozygous individuals.
Cross: BB x Bb
Gametes: B B B b
F1)
50% of the progeny will be homozygous BB
50% of the progeny will be heterozygous Bb
100% of the progeny will express the dominant trait.
The correct option is C. All of the offspring will exhibit the dominant trait.
