Mitochondrion; crista Mitochondrion; crista Mitochondrion is a constituent part of crista. Crista is a constituent part of mitochondrion. Mitochondrion and crista are separate structures with no particular relationship to each other.
1. Mitochondrion; crista:
a. Mitochondrion is a constituent part of crista.
b. Crista is s constituent part of mitochondrion.
c. Mitochondrion and crista are separate structures with no particular relationship to each other.
2. Gobi complex; nucleus
a. Goo complex is a constituent part of nucleus.
b. Nucleus is e constituent part of Gobi complex.
c. Goo complex and nucleus are separate structures with no particular relationship to each other.
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.
QUESTION 31 Chipmunk mitochondrial DNA was fingerprinted using the single primer amplified region technique (SPAR) and the PCR reaction. One four base primer was used. If the DNA from chipmunk mitochondria is a circlular piece of DNA about 16000 base pairs long, how many fragments should be produced by this technique
Answer:
It depends on the size of the amplified DNA fragments (for example for SPAR markers consisting of 200 bp in length >> 1600 / 200 = 8)
Explanation:
The PCR based single primer amplification reaction (SPAR) methods are tools for detecting genetic diversity by using DNA markers such as Simple Sequence Repeats (ISSRs), Minisatellite DNA regions (DAMDs) and Random Amplified Polymorphic DNAs (RAPDs), which can be used alone or combined with each other. In the last years, the SPAR methods have gained attention in the scientific community because they are cost-effective and highly effective for the detection of both intraspecific and interspecific genetic variation. In the SPAR methods, the size of the bands will depend on the length of the amplified DNA fragments.
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.

How is energy related to the change of state represented by the model? Atoms gain energy as a gas changes to a solid. Atoms gain energy as a gas changes to a liquid. Atoms lose energy as a gas changes to a solid. Atoms lose energy as a gas changes to a liquid.
Answer:
C. Atoms lose energy as a gas changes to a solid.
Explanation:
Physical changes of matter take place by adding or removing energy from the matter.
In the given images, The left cylindrical is showing gas phase while the right cylindrical is showing a solid phase.
The process of conversion of gas into solid is called deposition. Deposition process takes place when atoms lose their energy and have high kinetic energy so they directly convert into solid and not into liquid.
Hence, the correct option is "C".

Answer the following True or False: A hypothesis test was conducted to see if a new HIV vaccination reduces the risk of contracting the HIV virus. The implication of a Type II error from the clinical trial is that the vaccination will not be approved when it indeed does reduce the risk of contracting the HIV virus.
Answer:
The correct answer is - true.
Explanation:
Type I error occurs when the alternate hypothesis is accepted though it is false. A type II error is the failure to reject a false null hypothesis or an alternative hypothesis is rejected even though it is true.
For instance of type II errors: a blood test designed to detect the disease failing to detect the disease in a patient who really has the disease. In the given case vaccination not approved even though reduce the risk of contracting the HIV virus.
Thus, the correct answer is - true.
Which glial cells support neurons metabolically
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%
