How does cell volume affect nutrient exchange between the cell and its external environment?
a. Cells with a large volume and small surface area are well-adapted for nutrient
exchange.
b. Very large cells are the best adapted for nutrient exchange.
c. The ratio of cell volume to surface area determines the efficiency of nutrient
exchange.
d. Very small cells are the best adapted for nutrient exchange.
e. Nutrient exchange is not impacted by cell volume.
Answer:
d. Very small cells are the best adapted for nutrient exchange.
Explanation:
The need to be able to pass nutrients and other substances into and out of the cell limits how big cells can get. The larger a cell is, the more difficult it is for nutrients and gases to move in and out of the cell because the volume is larger than the surface area. Smaller cells can exchange nutrients with the external environment more quickly.

Explanation:
1. Remember, the term Genetic diseases implies that they are diseases inherited genetically. Thus, environmental conditions have no direct influence on the spread of genetic diseases.
2. We can make this conclusion because research has shown that genetic disorders are more common in families with one affected member as compared to the general population. In other words, the family's medical history is part of the determinant factor.
3. Some recent studies have shown that both members of identical and fraternal twin pairs do not have the same likelihood of expressing the same genetic disease.
4. Genetic diseases do not occur at the same rate in all human populations. Researchers often make reference to findings discovered from surviving victims of the Hiroshima nuclear bomb which is said to be the cause of some genetic diseases. Also, the sickle cell genetic disease rate of occurrence is believed to be high in Africa than in North America.
5. Scientists believe that there is no specific age of onset of genetic disease. That is to say, they may appear within an age range but not a specific age.
6. Indeed, many human and animal genetic disorders share similar characteristics . A good example is the albino genetic order in humans has been discovered to share similar characteristics that is found in animals.

I'm dropping out
I'm tired of University, I'm sick of all my professors for treating me harshly especially during these hard times, and I hate taking midterms.
I'm currently a college freshman in the middle of the semester, and things have been pretty tough. I've been procrastinating the whole week because I had everything going on and I couldn't keep up. I'm a biology major (pre-med) and I have to take two science classes. I suck at managing time and I suck at studying. I feel like I cannot do this. Also, whenever I do my assignments, my professors grade so friggen harshly & give me unfair grades even though I work all the way through midnight finishing it.
I'm a good student, it's just that you know some people can be burned out. I am burned out and college has just been draining my soul each day. Should I drop out?

Explanation:
A sample of peptide of unknown sequence was treated with trypsin to produce the following smaller peptides:
1) Met-Val-Ser-Thr-Lys
2) Val-Ile-Trp-Thr-Leu-Met-Ile
3) Leu-Phe-Asn-Glu-Ser-Arg
Another sample of the same peptide was treated with chymotrypsin and gave the following smaller peptides:
1) Asn-Glu-Ser-Arg-Val-Ile-Trp
2) Thr-Leu-Met-Ile
3) Met-Val-Ser-Thr-Lys-Leu-Phe
What is the sequence of the original peptide?
Answer:
The sequence is >> Met-Val-Ser-Thr-Lys-Leu-Phe-Asn-Glu-Ser-Arg-Val-Ile-Trp-Thr-Leu-Met-Ile, or abbreviated M-V-S-T-K-L-F-N-E-S-R-V-I-W-T-L-M-I
Explanation:
Trypsin is a serine protease enzyme capable of hydrolyzing different types of proteins. This enzyme is used in biotechnology and molecular biology to hydrolyze at the carboxyl side of arginine or lysine residues. Moreover, chymotrypsin is another digestive protease that also catalyzes the breakdown of proteins into small polypeptide chains. This enzyme cuts the C-terminal side of aromatic amino acids such as tryptophan (W), tyrosine (Y) and phenylalanine (F) on peptide chains.
1. John is suffering from autosomal dominant deafness (D) and his wife Mary is normal.
Considering complete penetrance for this trait (P=1), what is the probability that this
couple's first child would have this disorder?
Answer:
Autosomal dominant inheritance: A person affected by an autosomal dominant disorder has a 50 percent chance of passing the mutated gene to each child. The chance that a child will not inherit the mutated gene is also 50 percent. However, in some cases an autosomal dominant disorder results from a new mutation that occurs during the formation of egg or sperm cells or early in embryonic development. In these cases, the child's parents are unaffected, but the child may pass on the condition to his or her own children.

: Research coal and natural gas as a source of energy.
Answer:
Its fossil energy non renewable source
Explanation:
Answer:
Coal vs Natural Gas Coal is a sedimentary rock with a high concentration of hydrocarbons and carbon. Given that it takes millions of years for coal to develop, it is categorized as a nonrenewable energy source. Coal is combustible and typically black or brownish black in color. Natural gas is a naturally occurring mixture of gaseous hydrocarbons, mostly methane, with small traces of other higher alkanes. Coal and natural gas have different benefits, effects on the Earth, and impacts on human health. Natural gas is a fossil fuel; however its global warming emissions are significantly smaller compared to those from coal or oil. When combusted in a modern, efficient natural gas-power plant, natural gas releases between 50 and 60 percent less carbon dioxide (CO2) than pollution from an average modern coal plant. The impacts of human health due to air pollution from both coal and natural gas can lead to asthma and breathing issues, brain damage, heart problems, cancer, neurological disorders, and early mortality. These conditions are from the releasing of mercury, lead, sulfur dioxide, nitrogen oxides, particulates, and other heavy metals in to the air. In 2021, electricity producers in the United States paid roughly $4.98 per million British thermal units for natural gas. Coal power plant operators, on the other hand, paid an average of 1.98 US dollars; in simpler terms, the cost of generating electricity is cheaper using coal. Coal is a reliable, cheap source of power. It is easy to store, reduces dependence on oil, and creates many jobs. On the other hand, when burned to create power, natural gas produces roughly half the carbon dioxide (CO2) and one-tenth the air pollutants produced by coal. By using gas instead of coal, there is significant potential to cut near-term CO2 emissions and air pollution by using gas over coal. It is adaptive. A gas-fired power plant starts and stops much faster than a coal-fired unit. Both gas and coal have plentiful pros and cons however gas is the better one to use. Gas is more abundant and pollutes more than coal. Though coal is cheaper, the effects on the environment and human health are not worth the gamble. https://www.shell.com/energy-and-innovation/natural-gas/natural-gas-and-its-advantages.html http://groundtruthtrekking.org/Reports/Coal-Electricity-Prices-Externalities-Analysis/1/Coal-Electricity-Prices-Externalities-Levelized-Cost/ https://www.statista.com/statistics/189180/natural-gas-vis-a-vis-coal-prices/

Answer:
The correct answer is "Yamnaya".
Explanation:
In genetics, a population or genetic bottleneck is defined as a reduction on the size of a population as a result of an environmental effect or human intervention. Regarding the Y chromosome bottleneck, the Yamnaya is an ancient population that contributed the most due to its sex-biased and stratified culture. The Yamnaya were violent and left behind many male skeletons, where just few type of persons were able to reproduce.
