An estuary collects sediments from the ocean and rivers that feed into it. The sediments swirl around and then settle to form a mudflat. Eel grass is then established on the mudflat. The ecosystem changes over time and ultimately develops into a salt marsh that contains mangrove trees.
Which of the following is likely NOT involved in this example of ecological succession?
A)
The rotting remains of plants add to the fertility of the soil.
B)
The soil becomes so fertile that eel grass is replaced by other plant species.
C)
The roots from plants help stabilize the sediment, keeping it in place.
D)
The concentration of salt becomes so high that all plant life is destroyed.

In the logistic growth model, as a population approaches the carrying capacity, what happens to its growth rate?
A
becomes exponential
B
doubles
C
increases
D
slows to zero
In the logistic growth model, as a population approaches the carrying capacity, the growth rate of the population will slow down to zero. Thus, the correct option is D.
What is Logistic growth model?The logistic growth model is a parameter which represents the rate at which the population would grow if it were unencumbered by the environmental degradation. A second parameter, that is K, represents the carrying capacity of the system of species which are being studied.
In logistic growth, a population's per capita growth rate gets smaller and smaller as the population size when it approaches a maximum imposed by the limited resources in the environment, known as the carrying capacity (K). Exponential growth model produces a J-shaped curve, while logistic growth produces an S-shaped curve.
Therefore, the correct option is D.

A brown guinea pig mates with a white guinea pig. All of the babies have tan, or light brown fur. The hair color trait in guinea pigs is probably ____.
1. Sex linked
2. Recessive
3. Incomplete dominance
4. Codominant
Answer:
It would be sex linked.
Explanation:
As you know (if you do), when two animals mate, they combine their genes to make a baby. So of their skin colors are different like one is brown and one is white, then you get a baby that would look brownish white or have spots that are brown or white.

Drag each label to the correct location on the table. Sort the observations based on whether they are quantitative or qualitative.
Answer:
Qualitative observations are those that cannot really be counted or measured by empirical figures, but are rather described by the features they have such as their color or taste.
Quantitative observations can be measured and counted by empirical figures i.e. numbers such as age and temperature. Number operations such as addition can be performed on them as well.

Which of the following best explains the evolutionary basis of human skin color? two parents who are heterozygous for each of the alleles have a greater probability of having a child with medium skin than one with very light or very dark skin in a diverse population, the distribution of the trait will be a bell curve, so most people will fall in the middle the inheritance of the alleles from each parent is completely random but in a population there may be natural selective pressure from the environment to favor different levels of expression multiple genes and multiple alleles each have an additive effect on how intensely the trait is expressed.
Answer:
From the given Options, Option C is correct.
the inheritance of the alleles from each parent is completely random but in a population, there may be natural selective pressure from the environment to favor different levels of expression
Explanation:
The evolutionary basis of human skin color stems far back to the genetic mutations involved in skin pigmentation. Although the diversity of skin color is a characteristic trait of humans, These variants and their evolution reveal that the history of skin color is much older than previously thought.
The evolution of various variations in the human skin color is a result of selective forces which is an environmental factor that favors various levels of expression. Thus, the best option that explains the basis of human skin color in terms of evolutionary trend is Option C.
Which of the following is an example of genomic imprinting in humans? Which of the following is an example of genomic imprinting in humans? A random pattern of autosomal allele inactivation is observed. In some allele pairs, only the paternal sourced allele is expressed, and in others, only the maternal sourced allele is expressed. The maternal and paternal alleles of a gene pair are both expressed. Human males have only one Y-chromosome and one X-chromosome. One of the two X-chromosomes in females is randomly expressed and the other is repressed.
Answer:
In some allele pairs, only the paternal sourced allele is expressed, and in others, only the maternal sourced allele is expressed.
Explanation:
Genomic imprinting is an epigenetic phenomenon where alleles are differentially expressed depending on their parental origin (for example, paternally expressed when it is inherited from the father). Genomic imprinting is controlled by epigenetic modifications (for example, DNA methylation, histone acetylation, etc) which works together to preferentially activate the expression of the allele inherited from one parent and simultaneously silence or “imprint” the expression of the allele inherited from the other parent. In humans, an example of genomic imprinting is the case of the insulin-like growth factor 2 (Igf2) gene, which is maternally imprinted (repressed), thereby this gene is only expressed from the paternal allele.

Grasses → mice → cat → coyote A natural disaster of a fire has occurred what could happen to this food chain? The grasses will be gone and all of the consumers will be able to leave. The grasses will be gone and some of the mice will die but the number of cats and coyotes will remain the same. The grasses will be gone but the number of consumers will all stay the same. The grasses will be gone and any surviving consumers will have to look for new resources in that environment. Nothing will happen to this food chain.
Answer:
The grasses will be gone and any surviving consumers will have to look for new resources in that environment.
Explanation:
The fire will destroy the grass and harm some of the consumers. Without grass, the mice population will drop and that will cause the cat population to drop and that will lead to the coyote population to also decline. The remaining consumers will have to move to find further resources to survive.
Answer:
The answer will be D
