Which statements correctly describe mutations in gametes and mutations in somatic cells?
Mutations to somatic cells are only present in the type of cell in which the mutation occurred.
Mutations to gametes are more likely to be beneficial than mutations to somatic cells.
Mutations to somatic cells will be inherited by an organism's offspring.
Mutations to gametes can be passed on to an organism's offspring
O Mutations to gametes do not involve changes in the DNA.
Mutations to somatic cells are transferred to daughter cells.
Answer:mutations to gametes can be passed on to an organism's offspring and mutations to somatic cells are only present in the type of cell in which the mutation occurred.
Explanation:The mutation in the somatic cells is known as somatic mutations. As they do not take place in the cells, which give rise to gametes, thus, the mutation is not inherited to the next generation by the sexual means.
On the other hand, the genetic mutations take place in the germline cells, that is, egg and sperm, because of this the mutations possesses the tendency to get passed on from one generation to another.
Thus, mutations are only passed on to offspring when they take place in germ cell DNA. The other kind of cells, the somatic cells refers to the rest of the cells in the body and mutations, which takes place in these cells do not get inherited further to the offspring.
Hence, the correct statements are
In plant cells, how are chloroplasts and mitochondria related?
A. Chloroplasts manufacture food;mitochondria break down the food and convert it to energy
B. Chloroplasts package nutrients;mitochondria deliver the nutrients to other parts of the cell
C. Chloroplasts absorb water from the surrounding tissue; mitochondria store water
D. Chloroplasts direct the functions of the cell;mitochondria deliver messages to other parts of the cell.
Answer:
Explanation:
Answer is A
Mitochondria are the "powerhouses" of the cell, breaking down fuel molecules and capturing energy in cellular respiration. Chloroplasts are found in plants and algae. They're responsible for capturing light energy to make sugars in photosynthesis.

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

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 :)

Question 2 of 10
Which of the following is a description of a resource that belongs to a country
with a high carrying capacity?
A. Homes are small and house many people.
O B. Food is brought in from other places.
C. Water comes directly from bodies of water.
OD. Food is not always available.
SUBMIT
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.

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.
