Answer:
Over-watering severely limits, even cuts off the supply of oxygen that roots depend on to function properly, meaning that plants do not get adequate oxygen to survive. Furthermore, too much water can also lead to root rotting and the irreversible decay of roots.

c.
Most of the energy collected by an organism is not passed on to other organisms.
d.
Tertiary consumers collect the most energy in an ecosystem.
Answer: C - Most of the energy collected by an organism is not passed on to other organisms.
Explanation:
right on edge 2020
also only 10% of energy is transferred to the next trophic level
The best description of energy transformation in an ecosystem is most of the energy collected by an organism is not passed on to the other organisms. Thus, the correct option is C.
What is Energy transformation in an ecosystem?Energy is transferred between different organisms in a food web from producers to different consumers. The energy is used by the organisms to carry out most of the complex tasks in the food web. The vast majority of energy which exists in a food web originates from the sun and is transformed into chemical energy by the process of photosynthesis in the plants.
Energy transformation in an ecosystem follows 10% law, where only 10% of the energy is transferred to the next trophic level in an ecosystem. Thus, most of the energy collected by an organism is not passed on to other organisms.
Therefore, the correct option is C.

how do villi help to increase the absorption of digested food in to the blood stream
Answer:
The cells of the villi and another part of the small intestine, known as the crypts, transport food from the digestive tract into the bloodstream, where they can be used by the body. The villi aid in absorption by increasing the surface area of the intestine and contain specialized cells which transport different types of nutrients into the blood.
Explanation:
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.

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.

: 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/
