Black bears are not well evolved to survive in arctic temperatures like polar bear are so the population of black bears in that area would probably decrease until it is wiped out because they can't survive there.
What would happen to an animal cell with an internal salt concentration of 10% if it were placed in a salt solution with a concentration of 30%?
O The water would move out of the cell and the cell would decrease in size.
O The water would move into the cell and the cell would increase in size.
O The salt would move into the cell and the cell would increase in size.
O The salt would move out of the cell and the cell would decrease in size..
Answer:
The water would move out of the cell and the cell would decrease in size.
Explanation:
This question is depicting OSMOSIS, which is the movement of water from a region of high concentration (low solute concentration) to a region of low concentration (high solute concentration) across a semi-permeable membrane. This movement is caused when a concentration gradient forms between the two sides of the membrane.
In this case, an animal cell contains an internal salt concentration of 10% while the salt solution has a concentration of 30%. This means that the animal cell is hypotonic (contains high water concentration) to the salt solution, hence, water would move out of the cell and the cell would decrease in size

Phosphorylation is an example of a post-translational modification of a protein. These modifications are covalently attached to the protein and can have significant effects on its function.
These affects include altering its activity, its binding to other proteins, and where it is found in the cell.
However, post-translational modifications do not affect the amino acid sequence of the protein.

Describe how traits are inherited through traits sexual Reproductions
WILL MARK AND 5 STARS
Answer: sexual reproduction is the union of male and female gametes to form a fertilized egg, or zygote. The resulting offspring inherit one half of their traits from each parent. The process where haploid sex cells are created from diploid parents is called meiosis, and it occurs only in the reproductive organs.
Explanation:
i have advanced so this is what i got right
Answer: In sexually reproducing organisms, each parent contributes half of the genes acquired (at random) by the offspring. Individuals have two of each chromosome and hence two alleles of each gene, one acquired from each parent. These versions may be identical or may differ from each other.

A geologist is studying a mountain. It is made up of many relatively even
layers of igneous rock. What can the geologist conclude about how the
mountain formed?
A. It formed when an earthquake caused faults to form in a body of
rock.
B. It formed when a glacier melted and deposited rock and sediment.
C. It was formed by many layers of sediment piling up.
D. It was formed by a series of volcanic eruptions.
The mountain was formed by a series of volcanic eruptions. Option D
What can be concluded?The geologist can infer from the data that the mountain was created by a sequence of volcanic explosions. It is stated that the mountain is composed of numerous, generally uniform strata of igneous rock.
In most cases, molten material such as lava or magma that is ejected during volcanic eruptions solidifies to produce igneous rock.
Multiple igneous rock strata may accumulate over time while the volcanic activity persists, eventually producing a mountain.

(06.02 MC) Which of the following correctly explains the role of antibiotics in the human body? (2 points) a They break down damaging toxins created by bacteria. b They increase the number of white blood cells in the blood. c They rupture the cell wall or prevent protein synthesis in bacteria. d They reduce the effects of fever, swelling, and inflammation in the body.
Answer:
The beneficial role of antibiotics in the human body is given because they produce rupture the cell wall or prevent protein synthesis in bacteria.
Explanation:
Antibiotics are a group of drugs that fight bacteria, eliminating them, to cure infectious diseases.
The mechanisms of action of antibiotics aim to break the bacterial protection or interfere with their vital functions to make them unviable:
Destruction of the bacterial wall or membrane. Interference with protein synthesis. Inhibition of the synthesis of nucleic acids.In general, the effects of antibiotics on bacteria are to rupture the cell wall or prevent protein synthesis. Through these mechanisms, antibiotics eliminate and prevent the reproduction of pathogenic bacteria, thus eliminating the infections they produce.
The other options are not correct because:
a. Breaking down damaging toxins created by bacteria is an anti-toxin function.
b. Antibiotics do not increase the number of white blood cells in the blood.
d. Reduction of the effects of fever, swelling, and inflammation in the body is a function of antipyretics and anti-inflammatories.
Answer:
They rupture the cell wall or prevent protein synthesis in bacteria.

Describe the alternation of generations in plants. (2 points)
Answer:
Alternation of generations (also known as metagenesis) is the type of life cycle that occurs in those plants and algae in the Archaeplastida and the Heterokontophyta that have distinct haploid sexual and diploid asexual stages. ... The haploid spores germinate and grow into a haploid gametophyte.
Explanation:
yw
Answer:
Alternation of generations describes a plant's life cycle as it alternates between a sexual phase, or generation and an asexual phase. The sexual generation in plants produces gametes, or sex cells and is called the gametophyte generation. The asexual phase produces spores and is called the sporophyte generation.

Student 3 said the immune system was also important because it releases sweat from the body while running, which the cardiovascular system will transport away from all the cells.
C.
Student 1 said the respiratory system was also important because it brings oxygen into the body while running, which the cardiovascular system transports to all the cells.
D.
Student 4 said the muscular system was also important because it produces nutrients in the body while running, which the cardiovascular system will transport away from all the cells.

Is a cell membrane more like a brick wall or a chain-link fence? Why?
Answer:chain-link fence
Explanation:a cell membrane is partial permeable which means that it lets some substances through but not other.
Answer:
Chain-link fence
Explanation:
Cell membranes are barriers that decide which molecules enter and exit the cell, and how much of them come in. So things are able to pass through them.
If it were a brick wall, it would not let anything pass through.
So it is more like a chain-link fence, but with more control over what passes through it.
Can someone please help me with these 2 questions? ILL GIVE BRAINLIEST
Answer:
1: The higher the force applied to the ball, the harder to make a home run because of the third law: every action has a reaction, the reaction is absorbed by the bat.
2:Same equation: F=MA from the second law, if the ball has a higher mass, it will have a higher force.
Explanation:
The third rule, which states that every action has a response, which is absorbed by the bat, makes it tougher to hit a home run the more power is given to the ball.
Explain Newton's law.Newton's laws of motion are three fundamental physical laws that describe the behavior of objects in motion and how they interact with forces. The laws were first published by Sir Isaac Newton in 1687.
Law of Force and Acceleration - The acceleration of an object is directly proportional to the net force acting on the object and inversely proportional to its mass. This law is often expressed as F=ma, where F is the net force acting on an object, m is the mass of the object, and a is the acceleration of the object.
Law of Action and Reaction - For every action, there is an equal and opposite reaction. This law states that when one object exerts a force on another object, the second object exerts an equal and opposite force on the first object.
