g The Electron Transport Complex (ETC) consists of four proteins. How many of these proteins directly contribute to the proton gradient by moving protons across the membrane?
Answer:
Three proteins directly contribute to the proton gradient by moving protons across the membrane
Explanation:
The Electron transport chain is a group of proteins and molecules incrusted in the internal mitochondrial membrane and organized into four complexes, I, II, III, and IV. These complexes contain the electron transporters and the enzymes necessary to catalyze the electron transference from one complex to the other. Complex I contains the flavine mononucleotide -FMN- that receives electrons from the NADH. The coenzyme Q, located in the lipidic interior of the membrane, conducts electrons from complex I and II to complex III. The complex III contains cytochrome b, from where electrons go to cytochrome c, which is a peripheric membrane protein. Electrons travel from cytochrome c to cytochromes a and a3, located in the complex IV. Finally, they go back to the matrix, where they combine to H+ ions and oxygen, to form the water molecule. As electrons are transported through the chain, protons are bombed through three proteinic complexes from the matrix to the intermembrane space. These are complexes I, III and IV.

ABO blood typing uses 3 alleles. From your course notes answer the following two questions: Which two are dominant? _________ Write the two dominant allele genotypes, using the capital letter I, and then a superscript for each of them. __
Answer and Explanation:
Given that the ABO blood typing uses 3 alleles
The blood type of ABO could find out by considering three different alleles i.e [tex]I^{A}, I^{B}\ and \ i[/tex]
where,
[tex]I^{A}\ and\ I^{B}[/tex] = co-dominant
i = recessive
The dominant allele genotypes are as follows
For type A = [tex]I^{A} I^{A}/ I^{A}\ i[/tex]
For type B = [tex]I^{B} I^{B}/ I^{B}\ i[/tex]
For type AB = [tex]I^{A} I^{B}[/tex]
Therefore the above two are dominants and the same is to be considered

Do you agree or disagree with the argument that humans are fundamentally incapable, as a species, of living sustainably?
Answer:
I disagree because there are examples that contradict this assertion
Explanation:
In the last years, sustainable human development has been one of the most important challenges in order to avoid Earth's collapse. In accordance with this aim, many people around the world are learning to responsibility use natural resources and live in communion with ecosystems capable of providing the primary matter required for economic progress. Examples of human groups that learned to use the available resources in a sustainable way include isolated societies living in forest areas, which live independently from the external globalization phenomenon. Moreover, in many countries, the percentage of energy obtained from clean sources is progressively increasing year by year, thereby supporting the fact that human societies can live sustainably.

What can a person do to limit exposure to X-rays?
wear sunblock
avoid cigarette smoke
wear a protective vest avoid chemicals
X-rays are a form of indirectly ionizing radiation, and it can be really nocive to the humans health, so limiting the exposure is always a priority.
Here the correct option is wearing a protective vest.
-------------------------------------
X-rays are a form of radiation that is indirectly ionizing. Remember that ionization is what causes damage to our cells, so is better to avoid exposures to these types of radiation.
Now, X-rays are strong enough that they can penetrate a lot of common materials (like wood, plastic, etc.) And once it enters in your body, the chain of reactions that starts can't be stoped by external means.
So what you need to do is limit the exposure as much as you can. Ideally, you shouldn't be near a source of X-rays, but if there is no other option, you should use protection against radiation.
It comes in different forms depending on what the application is, for example, there are led screens that you can use to put between you and the source, and these will reduce drastically the fluence (flux of photons) that gets to you.
Similarly, there are protective vests also made in part of led or other high atomic number materials, that absorb the photons and protect you.
So here the correct option is to wear a protective vest, from the given options, is the only one that will protect you from the X-rays.

What must occur for protein translation to begin? A water molecule must be added to the protein chain. A peptide bond must form between subunits of mRNA. The amino acid Cys must be picked up by tRNA. The codon AUG must be identified.
For protein translation to begin, the codon AUG must be identified.
PROTEIN SYNTHESIS:
Protein synthesis is the process whereby living organisms synthesize proteins using the information stored in their DNA. Protein synthesis involves transcription and translation. Transcription occurs in the nucleus where DNA is used as a template to synthesize mRNA. Translation occurs in the ribosome where mRNA transcript is used to synthesize amino acid sequence. During translation, mRNA codons are read and binded to by the anticodons of a tRNA molecule.However, for translation to begin, a specific mRNA codon called START CODON with the sequence: AUG must be identified first.

You observed many sand hill cranes on your walk. Two sand hill cranes flapped their wings and hopped up and down when you walked on the path near where their bright orange baby stood. You observed a(n) _______________.
Answer:
This question lacks options, the options are:
A) symbiosis
B) ecosystem
C) community
D) population
E) biosphere
The answer is D) Population
Explanation:
Living organisms in an ecosystem are usually found in numbers living together in a given area. This is termed POPULATION in ecology. A population refers to the group of living organisms that belongs to the same species living together in the same habitat and have the ability to interbreed i.e. mate and reproduce with one another.
This is the case in this question where many sandhill cranes (large flying birds) were observed in a particular area, which represented their habitat. Asides the group of sandhill cranes living together, they were also observed to be interbreeding. This was evident in the observation of two sandhill cranes hopping up and down around their bright orange baby. This shows that members of the population are capable of mating and reproducing fertile offsprings.
This observation completes what a POPULATION is all about, hence, a population was observed.

The uterine cycle describes the cyclic changes of thickening and degeneration that the endometrium goes through in a month. What is the order of events in one uterine cycle
Answer:
During the uterine month there are different phases through which the uterus passes, these phases are regulated by hormones and are responsible for producing the cycle necessary for fertilization.
Phase where menstruation occurs: This phase only happens if the woman was not fertilized and did not develop the diploid cell together with a sperm, since not being fertilized, all the uterine preparation that had been planned in the body for fertilization will be released as that we know "menstruation", in this phase estrogens and progesterone are low. The inner walls of the unfertilized uterus are released.
Follicular phase, in the follicular phase the ovaries prepare to release an egg and estrogen begins to rise. (From the first day of the period until ovulation)
Proliferative phase, in the proliferative phase, new vessels proliferate and the outermost layer of the uterus prepares itself for possible fertilization, is where spiral arterioles can begin to form again in the external cut of the myometrium.
Ovulation, here is where the mature ovum is called Graff's follicle, at this time estrogen reaches its peak and then descends.
Luteal phase, in the luteal phase the production of the luteal body is generated, at this stage progesterone takes center stage, and it is the range between ovulation and menstruation (if not fertilized)
Last phase, secret phase, in this phase there are two possible ends, if the woman is fertilized, the egg cell implants and begins the development of the embryo and if it is not fertilized, the entire external cut of the myometrium is prepared to be secreted.
Explanation:
A very important fact to clarify is that women are born with a quantity of ovules that at the end of this uterine cycle ceases to exist, this process is what we know as menopause.
That is to say that women have a quantity of ovules that will one day run out, and the body releases them from the menarche or the first menstruation, generating that in each released ovule a uterine cycle is completed, the day they end the woman will have reached menopause and would have no chance of being fertilized or completing the uterine cycle.
superficial layer of the endometrium is shed
basal layer of endometrium grows, forms gland and blood vessels
enriched endometrial blood supply
endometrial glands secrete nutrients into uterus

At low frequencies during DNA replication, an extra nucleotide maybe inserted into the DNA strand. If this occurs within a gene, what would be the effect on the protein product
Answer:
1. It could result in a loss of function of the protein product
2. It could result in a protein product with excessive activity
3. It could result in altered structure of the protein
Explanation:
Any changes that occur in the nucleotide sequence in the DNA of an organism is known as a mutation. Various forms of mutation can occur in the DNA sequence of an organism which could be as a result of insertion or deletion of a nucleotide in the DNA sequence.
Insertion of an extra nucleotide into a DNA strand within a gene could have any of the following effects on the protein protein;
1. It could result in a loss of function of the protein product of the gene whereby the protein can no longer carry out its normal functions
2. It could result in a protein product with excessive activity other the normal range at which it functions.
3. It could result in altered structure of the protein either in the primary, secondary, tertiary, or quaternary structure

A student recorded the height of each student in the school. She then made a bar graph of her results. She observed
that the results form a bell-shaped curve. The student could use her graph as evidence to support which argument?
Height is affected by multiple pairs of genes on different chromosomes.
tre weles for tall height and short height are codominant.
the allele for being tall is dominant to the allele for shorter heights.
There are three alleles for height that demonstrate incomplete dominance
Answer:
Height is affected by multiple pairs of genes on different chromosomes.
Explanation:
The quantitative traits are those whose inheritance pattern is the result of the action of multiple genes that act together with the environment. The distribution of quantitative traits in the population follows a bell-shaped curve, which is referred to as normal distribution or Gaussian distribution. These traits are 'quantitative' because they vary among individuals in the population to produce a continuous range of phenotypic values. Examples of quantitative traits include, among others, metabolic rate, height, and weight.

Many of the quantitative methods discussed are popular because they enable the microbiology researcher to selectively count live cells only. Why do you think this might be an important or desirable feature in a medical or environmental research situation? Provide a scenario in which it might not be important to differentiate between live and dead cells when counting cell numbers.
Answer:
to count cancer cells killed during chemotherapy
Explanation:
There are different methods for counting live cells and they include, among others, counting chambers (e.g., a hemocytometer), image analysis, flow cytometry, spectrophotometric techniques, impedance detection, etc. These laboratory techniques can be used to detect both live and dead cells. In flow cytometry, for instance, it is possible to detect death cells by analyzing the loss of membrane integrity, which is an indicator of death. However, in certain situations, is not required to differentiate between live and dead cells, and thus it is only required to know the number of cells that a sample contains (for example, for counting the number of immortalized cells cultured over several generations).
