Answers

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.

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 :)

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

Answers

Answer:

c

Explanation:

cause it comes straight from the creek behind the houses

Carrying capacity defines the population size supported by a region. Water coming directly from water bodies suggests a high carrying capacity. Thus, option C is correct.

What is carrying capacity?

Carrying capacity is the quantity of the organisms or the population that can be supported in a habitat without any degradation and damage to the environment. It is a crucial factor in ecology.

It can be high and low depending on the availability of water, food, and space. A high carrying capacity can support a large population than a low carrying capacity because of the abundant resources.

Small homes with large family members, imported food items, and scarcity of food are limiting factors that are not the property of the high carrying capacity, instead, abundant availability of water is the characteristic of the high carrying capacity.

Active transport moves molecules from and to which concentration?
A: high to low
B: low to high
C: low to lower

Answers

Required Answer : -

Option (B) low to high is right Answer

▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬

We know that, Active transport moves ions and molecules across a membrane against the concentration gradient. It requires energy.

The characteristic features of active transport are:

-The movement of molecules in case of active transport is from lower concentration to higher concentration so it shows uphill transport.

-These have carrier proteins that are highly specific like enzymes for the substances to be carried across the membrane.

-The process of active transport can be inhibited by inhibitors that react with the protein side chains.

-The transport rate reaches its maximum when all the protein carriers are in use or get saturated with the substances to be carried.

The various types of processes that depend on active transport are:

-Absorption of amino acids from the gut.

-Absorption of mineral ions by plant roots.

-Excretion of urea and hydrogen ions by the mammalian kidney.

-Exchange of sodium and potassium ions in nerve cells.

-Filling of the contractile vacuole in amoeba.

The phloem in the leaves of a plant is rich in sugars because of the high rate of active transport.

Additional information :-

Some intrinsic protein molecules function as molecular pumps. These permit the cell to go for active transport to accumulate glucose or ions against the concentration gradient. Cells that undergo active transport have abundant mitochondria that provide ATP needed to power active transport.

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

Answers

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.
