the part of the cell that is hydrophobic (water-fearing) is the? __________
A, Whole cell membrane.
B, Fatty-acid tail.
C, Phosphate head.
D, None of the above.
PLEASE HELP BY TODAY!
Answers
Answer: B Fatty-acid tail
Explanation:
I have attached an image of what the cell membrane looks like, there's something called a phospholipid which makes up the membrane of the cell and as you can see, the head of the phospholipid is faced outwards while the hydrophobic tail is safe on the inside. The inside and outside of the cell has a lot of liquid and water so the hydrophobic (water fearing) part of the phospholipid (the tail) had to be protected and facing inwards away from it! Hope this helps, I'm in AP Biology right now :)

Explain the variation and distribution of expressed traits in a population in regards to the Sama-Bajau people and enlarged spleen. How does having an enlarged spleen benefit?
Answers
It is common for Sama-Banjou people to have an enlarged spleen, this is the result of environmental factors as a larger spleen helps them to dive better.
In most people, an enlarged spleen is not common and it is often related to specific conditions and diseases. Due to this, the percentage of people with an enlarged spleen is quite low.
Despite this, it has been found many Sama-Banjou people have an enlarged spleen and this is the result of environmental factors. Indeed, Sama-Banjou people have relied on diving to survive for centuries as they collect seashells from the seafloor.
This condition has led to bigger spleens, these bigger spleens increase the amount of oxygen while diving, and therefore, help them to dive for longer periods.

rita has two small containers one holding liquid and one holding a gas rita transfers the substances to two larger containers compare the behaviors in the atoms in the liquid and in the gas once they are moved to larger containers
Answers
Answer:The behavior of the both liquid and gas will be different in some aspect and same in the other, lets see how:
Explanation:
As we have studies that liquids donot have a specific shape but do have a specific volume. So when the liquid will be transferred from small to large container, it will adapt the shape of new container but its volume will stay same as it was in old container.
On the other hand, about gases, we know that they donot have specific shapes and the volume is also not definite and depends on the shape of container. Therefore, the gas atoms will freely move in the container and the volume will be changes in large container.

2.false (not sure)
3. Cellular respiration is the process through which cells convert sugars into energy.
4 C6H12O6 + 6O2 → 6CO2 + 6H20 + energy (Glucose + Oxygen yields Carbon Dioxide + Water + Energy)
5. Fermentation is a chemical process by which carbohydrates, such as starch and glucose, are broken down anaerobically.
6 anaerobic
7 alcoholic and lactic acid.
8 Alcoholic fermentation is a biotechnological process accomplished by yeast, some kinds of bacteria, or a few other microorganisms to convert sugars into ethyl alcohol and carbon dioxide. ... Alcoholic fermentation begins with the breakdown of sugars by yeasts to form pyruvate molecules, which is also known as glycolysis.
9 In this reaction, a phosphate group (in red) is transferred from phosphocreatine to ADP to form ATP very rapidly, allowing muscle contraction to continue for about 10 seconds. When phosphocreatine is depleted, the muscles must turn to metabolism of fuel molecules to produce more ATP to power physical activity.
10 At this point, the runners' muscle cells are producing most of their ATP by lactic acid fermentation, which can usually supply enough ATP to last about 90 seconds.
12 After that, the body begins to break down other stored molecules, including fats, for energy. If photosynthesis is the process that "deposits" energy in a "savings account," then what is cellular respiration? It is the process that "withdraws" energy.
13 Cellular Respiration and Photosynthesis are almost opposite processes because photosynthesis removes carbon dioxide from the atmosphere while cellular respiration puts back carbon dioxide. Cellular respiration uses oxygen and has it's waste product of carbon dioxide (CO2).

Fixation or volatilization, mineralization, nitrification, immobilization, and denitrification.
The sequence is as follow: Fixation, Nitrification, Assimilation, Ammonification and Dentrification.
What is a nitrogen cycle?The nitrogen cycle is the process by which nitrogen is converted into different chemical forms and moves between the biosphere, atmosphere, and geosphere. The stages of the nitrogen cycle, in order, are:
Nitrogen fixation: Nitrogen gas in the atmosphere is converted into a usable form, such as ammonia or nitrite, by nitrogen-fixing bacteria.
Nitrification: Ammonia or nitrite is converted into nitrate by nitrifying bacteria.
Assimilation: Nitrate is taken up by plants and converted into organic nitrogen compounds, such as proteins and nucleic acids, through the process of assimilation.
Ammonification: Organic nitrogen compounds are broken down by decomposers, such as bacteria and fungi, into ammonia or amino acids.
Denitrification: Ammonia or nitrite is converted back into nitrogen gas by denitrifying bacteria, completing the cycle.

[tex]BrainiacUser1357[/tex]
The model that shows the positions of the Sun, Moon, and Earth that have the greatest effect on ocean tides is the spring tide model.
What happen during the spring season?During spring tides, the Sun, Moon, and Earth are in alignment, which causes the gravitational pull of the Sun and Moon to reinforce each other, leading to higher high tides and lower low tides.
Spring tides occur twice a month, during the new moon phase and the full moon phase.
In contrast, neap tides occur when the Sun, Moon, and Earth form a right angle, which causes the gravitational pull of the Sun and Moon to counteract each other.
This leads to lower high tides and higher low tides. Neap tides also occur twice a month, during the first and third quarter moon phases.
It's important to note that the positions of the Sun, Moon, and Earth aren't the only factors that affect ocean tides. Other factors, such as the shape of the coastline and the depth of the ocean floor, can also influence the height and timing of tides in a particular area.

The production of alcohol by yeast cells is the result of anaerobic respiration. The correct option is D).
What are anaerobic respirations?All living cells undergo respiration, a chemical activity that releases energy from glucose. Without oxygen, anaerobic respiration occurs and produces less energy but does it more quickly. Fermentation refers to anaerobic respiration in microorganisms.
When you work out vigorously, your muscles engage in anaerobic respiration. Compared to aerobic respiration, less energy is released because glucose is not completely broken down.
During intense activity, lactic acid accumulates in the muscles. Later, the lactic acid must be oxidized to produce carbon dioxide and water.
Therefore, the correct option is D) Anaerobic respiration.
