Explanation:
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!
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 :)

is gene paired on endosperm cell?
Answer:
yes
Explanation:
What is the genetic makeup of endosperm?
One sperm fuses with the egg to form a diploid zygote, and the other sperm fuses with two female-gametophyte nuclei (known as polar nuclei) to form the triploid primary-endosperm nucleus. Therefore, the endosperm, which devel- ops from this triploid nucleus, has an unusual genetic composition

1. Describe the flow of energy from the sun to a producer, like grass, and then to a consumer, like a rabbit. Type your answer here:
Explanation:
The Sun then provides energy to the grass through the process of photosynthesis. The rabbit eats the grass, and the rabbit absorbs its energy. Finally, the snake eats the rabbit, and it absorbs the rabbit's energy. Energy travels from the Sun and moves through the ecosystem with each consumer along the chain.

ATP hydrolysis is the lysis of the molecule mediated by water. It releases a phosphate group and energy. It is a reversible reaction. (a) Reversible ATP hydrolysis. (b) added energy on the left and released energy on the right.
------------------------
ATP is a significant molecule involved in many of the cellular metabolic routes. These metabolic processes can either form it or break it.
ATP provides energy to many different functions in the organism.
ATP means adenosine tri-phosphate. It is composed of adenosine (an adenine plus a ribose), and three phosphate groups.
Note: you can also find adenosine Diphosphate (two phosphates) and adenosine monophosphate (one phosphate).
Oxygens from the phosphate groups only have a single bond to phosphate (there are no hydrogen bonds).
These single bonds, known as phophoanhydrid bonds, have a negative charge and tend to repel each other, making the molecule unstable.
So phosphate groups repel each other, and a considerable amount of energy is applied to keep them united. So phophoanhydrid bonds are high energetic bonds.
The forces that keep the phosphate groups together accumulate potential energy.
If these bonds are broken, part of this potential energy would be released.
When talking about breaking the molecule, we are referring to ATP hydrolysis. And the released energy is used in different cellular processes that require energy.
ATP Hydrolysis is the molecule lysis mediated by a water molecule.
ATP + H₂O ⇄ ADP + Pi + Energy
Pi is the released inorganic phosphate group.
This is a reversible reaction, meaning that the ADP can go back to ATP.
ADP + Pi + Energy ⇄ ATP + H₂O
(a) What is this a model of?
This model represents the reversible ATP hydrolysis.
In the superior part of the image, we can see an ATP molecule composed of adenine, ribose, and three phosphate groups. The yellow star behind represents the accumulated energy.
When ATP hydrolysis, it loses a phosphate group and part of the energy that was keeping this group in the molecule.
An ADP is composed after hydrolysis. We can see this molecule in the inferior area of the image.
ADP molecule is composed of adenine, ribose, and two phosphate groups.
Because hydrolysis is a reversible process, by adding a new phosphate inorganic group and energy, we can get a new ATP.
(b) Explain how you would change the model to make it correct?
What is wrong with this model is that instead of showing released energy during the hydrolysis process, it shows energy added to the reaction. In the same way, instead of showing added energy to the reversible reaction, it shows released energy.
Added energy and released energy must be changed.
Added energy should be on the leftReleased energy should be on the right---------------------------------

4. How would having a high blood viscosity affect your ability to climb stairs? Explain your answer interms of homeostasis of oxygen/carbon dioxide levels
Having a high blood viscosity will slow down ability to climb stairs. This is
because high blood viscosity is associated with high blood pressure.
The binding of oxygen to the blood is reduced in a blood with high viscosity
as there is difficulty in the transport of blood for oxygenation due to its
higher density. This allows fro accumulation of carbon dioxide in the blood
which is harmful to body cells.
High blood viscosity will therefore reduce one's ability to climb stairs and
perform other activities.
