Answer:
Explanation:
Osmosis is the spontaneous movement of molecules from low concentration to high concentration. The finger is hypertonic to the swimming pool, which means that it has a higher osmotic pressure. The pool is hypotonic to the finger, which means it has a lower osmotic pressure. Because osmosis goes from low to high concentration, water will seep into the finger, causing it to swell and become wrinkly. This balances out the concentration on both sides of the semipermeable membrane (skin on the finger) and makes them isotonic, meaning they have the same concentration.
During which phase of meiosis does the nuclear membrane reform around chromosomes?
Answer:
Telophase
Telophase. The final stage of mitosis, and a reversal of many of the processes observed during prophase. The nuclear membrane reforms around the chromosomes grouped at either pole of the cell, the chromosomes uncoil and become diffuse, and the spindle fibres disappear.

Some illnesses and harmful infections are caused by bacteria. These bacteria grow in the human body and often make people sick with symptoms like coughing, sneezing, and fever. These illnesses are not related to any genetic mutations or other problems with DNA.
Why would gene therapy fail to cure illnesses caused by bacteria?
Gene therapy reduces symptoms but never cures illnesses.
Gene therapy does not work on most people.
Gene therapy only focuses on replacing mutated genes.
Gene therapy is too long a process.
Answer:
Genes go brrrrrrrr
Explanation:
The answer is C because gene therapy is used to knock out, replace, or remove the mutated genes.

A cart accelerates at 2 m/s2 when a force of 60 N is applied. What is the mass of the cart? (Formula: F=ma)
0.03 kg
30 kg
62 kg
120 kg
Answer:
30 kg
Explanation:
Since a force of 60 N is applied, the mass of this cart is equal to 30 kg.
Given the following data:
Acceleration = 2 [tex]m/s^2[/tex]
Force = 60 Newton.
How to calculate the mass of this cart.From Newton's Second Law of Motion, the force exerted on the cart is given by this formula:
[tex]F=ma[/tex]
Where:
F is the force.m is the mass.a is the acceleration.Making mass the subject of formula, we have:
[tex]m=\frac{F}{a}[/tex]
Substituting the given parameters into the formula, we have;
[tex]m=\frac{60}{2}[/tex]
m = 30 kg.

All of the following are characteristics of proteins EXCEPT:
A They contain genetic information
B They can catalyze chemical reactions.
c They can transport materials.
D They can repair tissues.
Answer: A.
Explanation: Proteins are made by decoding genetic information carried by DNA, but contain no genetic information themselves. Although the sequence of amino-acids in a protein matches the code in DNA, there is no process for using protein as a template for DNA.
Proteins may be structural, like collagen in tendons or keratin in hair and fingernails, or enzymes active in metabolism, or in transport, such as haemoglobin that transports oxygen, or in transporting ions into and out of cells against a concentration gradient.

Photosynthesis uses energy from the Sun to make sugars such as glucose. What has to happen to the glucose before it can be used by plant cells?
A The glucose combines with another sugar to make usable energy.
B The glucose combines with oxygen to make usable energy.
OC The glucose combines with carbon dioxide to make usable energy.
OD Nothing has to happen to the glucose. Plant cells can use it as is.
Answer:
Respiration occurs when glucose (sugar produced during photosynthesis) combines with oxygen to produce useable cellular energy. This energy is used to fuel growth and all of the normal cellular functions.
D Nothing has to happen to the glucose. Plant cells can use it as is.
What happens to the glucose produced by plants?Glucose produced by photosynthesis is a simple sugar that is used by plant cells as a source of energy and as a building block for other organic compounds. The glucose can be transported within the plant and used directly by cells as a source of energy through cellular respiration.
In cellular respiration, glucose is combined with oxygen to release energy in the form of ATP (adenosine triphosphate), which is used to fuel various cellular processes. So, there is no need for glucose to undergo any additional chemical reactions before it can be used by plant cells.

Plant cells have a large central vacuole that hold water and can swell, which then results in other cell organelles being pushed against the cell membrane. Which of the following best explains how being close to the cell membrane could benefit a cellular process?
A. Nucleotides would have more access to space in the cytosol and become more concentrated, benifiting DNA replication.
B. Ribosomes would have more access to space in the cytosol and make more proteins, benifiting protein synthesis.
C. Mitochondria would have more access to glucose to convert into ATP, benifiting cellular respiration.
D. Chloroplasts would have more access to light energy to convert carbon dioxide and water in glucose, benifiting photosynthesis.
hi
D
is true
Well now check yourself please
Chloroplasts would have more access to light energy to convert carbon dioxide and water into glucose, benefiting photosynthesis. So the correct option is D.
What is a central vacuole?
A core vacuole that is hydrated. This organelle, which is surrounded by a single membrane, serves as a reservoir, waste disposal site, storage area, and even a way to maintain the cell's form. When the vacuole is completely filled with water, it pulls the cytoplasm into a narrow strip next to the membrane and expands like a balloon filled with water.
This turgor pressure maintains the cell's rigidity and gives plant structures like leaves their distinctive shapes. Long-term dehydration of a plant causes the central vacuoles to lose water, the cells to deform, and the entire leaf to wilt. In the vacuole, plants frequently store carbohydrates, ions, certain proteins, and sporadically pigments.
For instance, the pigments created and deposited in the central vacuole give flower petal cells their distinctive hue. In addition to making the plant poisonous to herbivorous animals, poisonous substances that might injure the cytoplasm are discharged into the vacuole.
Therefore, the correct option is D.
