Answer:
1. b. Crista is s constituent part of mitochondrion.
2. c. Gobi complex and nucleus are separate structures with no particular relationship to each other.
Explanation:
The crista is an integral part of the mitochondria. As you already know, mitochondria is a cytoplasmic organelle. it has two members that delimit it, the outer membrane is completely smooth, however the inner membrane is composed of numerous folds, that are called crista, and that spread through the interior of the mitochondria. These crista have as main function to increase the surface of the inner membrane.
The Golgi complex is a cytoplasmic organelle, as is mitochondria. The nucleus, however, is a cell structure, it is totally separated from the golgi complex and there is no particular relationship between these two structures.
The golgi complex participates in the storage and distribution of substances in the cell, while the nucleus is responsible for housing and protecting genetic information.

The nerve cells in your body must constantly remove substances from the cell against the concentration gradient. What type of process most likely takes place to remove substances from a cell against the concentration gradient? Explain.
Answer and explanation:
Active transport refers to a procedure, which withdraws substances from a cell against the concentration gradient. During the process, the molecules move from low concentration to a high concentration.
The mechanisms of active transport need the application of the energy of the cell, generally in the form of ATP. If a substance needs to move within the cell against its concentration gradient, that is, if the substance's concentration within the cell is more than its concentration in the extracellular fluid, then the cell must utilize energy to move the substance.

What is the allele frequency?
Answer:
Explanation:
Allele frequency is the how often or what's the percentage of a particular allele in a population. Allele is referred to as version of a gene that is located on the chromosome.
For example, a gene causing death in rats might have alleles, W and w. Each would be a separate allele and the frequency would be how often or what's the percentage of W or w that is present in the population.
Suppose we are trying to find frequency of W or w allele in a population then the formula is
Allele Frequency = [# of copies of certain allele (either W or w)] / [Total number of W and w alleles]
Now suppose we have 4 WW and 2 ww in a population.
First we count up W allele then we have (4 * 2)= 8 W (we multiplied by 2 because each organism has WW, 4 WW is short of of writing WW , WW, WW, WW)Same concept for 2ww, we have total w = 2 * 2 = 4wTotal alleles = W + w = 8 +4 =12
Allele Frequency for W = 8 / 12 = 66.67%
Allle Frequency for w = 4 / 12 = 33.33%

In 1998, paleoanthropologist Rick Potts published an article in The Yearbook of Physical Anthropology, a peer-reviewed journal. The article was titled “Environmental Hypotheses of Hominin Evolution.” In his paper, Potts claimed that great variations in environmental conditions over time were responsible for the adaptability of humans and the success of our species. Which would most likely be found in his paper?
This question is incomplete because the options are missing; here is the missing section:
Which would most likely be found in his paper?
A. A review of modern human anatomical structure.
B. Evidence of changing environmental conditions, with references.
C. The reasons competing hypotheses are wrong.
D. His opinion of what will happen to the survival of the human race.
The answer to this question is B. Evidence of changing environmental conditions, with references.
Explanation:
In texts such as scientific articles, the central point is expressed by the main claim or hypothesis as this is supported and explained through evidence in the articles. This means Potts article focuses on the environmental changes and how these contributed to the human species adaptability.
Due to this, it is expected the article explains the changes in environmental conditions, and the connection of these to adaptability. Moreover, because this is a scientific article all ideas should be supported with evidence collected by the author including references to other reliable sources. Thus, "evidence of changing environmental conditions, with references" is expected to be found in this article.
