Answer:
Channel proteins can aid in the facilitated diffusion of substances by forming a hydrophilic passage through the plasma membrane through which polar and charged substances can pass.
Explanation:
Answer: By forming a continuous protein pathway across the membrane, these proteins enable specific hydrophilic solutes to cross the membrane without coming into direct contact with the hydrophobic interior of the lipid bilayer. Carrier proteins and channel proteins are the two major classes of membrane transport proteins.
Why is ATP known as the energy currency?
5 line answer plz
Answer:
ATP is commonly referred to as the "energy currency" of the cell, as it provides readily releasable energy in the bond between the second and third phosphate groups. ... As a result, cells within the human body depend upon the hydrolysis of 100 to 150 moles of ATP per day to ensure proper functioning.In addition to providing energy, the breakdown of ATP through hydrolysis serves a broad range of cell functions, including signaling and DNA/RNA synthesis. ATP synthesis utilizes energy obtained from multiple catabolic mechanisms, including cellular respiration, beta-oxidation, and ketosis.
Explanation: is this good enough?
Answer:
Because its a sequence in which molecules can store their own energy and use it when needed such as in a chemical reaction , note that this is the main reason some molecules stay dormant during a chemical reaction and that is because they didn't use ATP
Explanation:
The principal molecule for storing and transferring energy in cells. It is often referred to as the energy currency of the cell and can be compared to storing money in a bank. ... AMP can then be recycled into ADP or ATP by forming new phosphoanhydride bonds to store energy once again. (This Is A Web Response) but feel free to use mine if it helps its a more simpler term.
How does a plants structure contribute to its ability to perform photosynthesis
Answer: 1. Leaves have a large surface area; this allows them to absorb more sunlight. They are also thin, meaning that carbon dioxide has a shorter way to travel.
2. stomata allow the entrance of carbon dioxide. The more complex adaptations are of the internal leaf structure.
If you start off with 12 strands of chromatin how many strand of chromatin do you need to end up with in each cell after meiosis
Answer:
3
Explanation:
If you start off with 12 strands of chromatin how many strand of chromatin do you need to end up with in each cell after meiosis after 3 stages.
What is meiosis?
In sexually reproducing organisms, meiosis is a kind of cell division that results in a reduction in the number of chromosomes in gametes (the sex cells, or egg and sperm).
Body (or somatic) cells in humans are diploid, meaning they have two sets of chromosomes (one from each parent). The egg and sperm that combine during fertilization must be haploid, or having only one pair of chromosomes, in order to sustain this state.
Each diploid cell divides twice during meiosis to produce four haploid daughter cells, which are the gametes.
Nearly every human cell contains 46 chromosomes, 23 of which come from one of our parents and 23 highly similar chromosomes from the other parent. The appropriate number of chromosomes in a cell is crucial.
Therefore, If you start off with 12 strands of chromatin how many strand of chromatin do you need to end up with in each cell after meiosis after 3 stages.

What is necessary for the process of active transport to occur
Answer:
THE use of energy (usually in the form of ATP) is necessary for the process of active transport to occur.
Energy in form of ATP is necessary for the process of active transport to occur.
WHAT IS ACTIVE TRANSPORT:Active transport is the type of transport that involves the movement of molecules with the aid of energy (ATP). Active transport uses energy to move molecules against a concentration gradient unlike passive transport.Therefore, this means that energy in form of ATP is necessary for the process of active transport to occur.

What are some ways that the biosphere interacts with the other three systems?
Answer:
Plants (biosphere) draw water (hydrosphere) and nutrients from the soil (geosphere) and release water vapor into the atmosphere. Humans (biosphere) use farm machinery (manufactured from geosphere materials) to plow the fields, and the atmosphere brings precipitation (hydrosphere) to water the plants.
Explanation:
Answer :Full Answer. A classic example of an interaction between spheres is when a plant (part of the biosphere), takes carbon dioxide from the atmosphere and water (the hydrosphere) through its roots from underground (geosphere) to perform photosynthesis, which provides the plant with food and releases oxygen into the atmosphere.

Which THREE statements describe how the models of mitosis and meiosis demonstrate genetic continuity?
Chromosomes are divided up evenly during Anaphase (Anaphase I of meiosis), ensuring that the daughter cells will have the correct number to reproduce.
In Interphase the chromosomes have duplicated, indicating that there will be enough genetic material to separate into daughter cells capable of reproduction.
In Prophase (Prophase I and II of meiosis) the spindles form, indicating that the chromosomes will be split evenly, and the daughter cells will receive the appropriate amount of genetic material.
In Metaphase (Metaphase II of meiosis) the chromosomes are lined up properly, indicating that the chromatids will separate evenly and provide the daughter cells with equal amounts of genetic material.
In Telophase (Telophase II of meiosis) the amount of chromatin present is equal to the amount present during Interphase, indicating that the daughter cells will receive the same amount of genetic material as the parent cell.
Answers: A,B,D
Explanation: :I took the test and got this question right .
The three statements that describes how the models of mitosis and meiosis demonstrate genetic continuity are listed and explain below.
In Anaphase, chromosomes line up in the middle of the cell while the spindle fibres pulls them apart.
Therefore the statement below about anaphase is correct.
Chromosomes are divided up evenly during Anaphase (Anaphase I of meiosis), ensuring that the daughter cells will have the correct number to reproduce.In interphase, the synthesis of DNA occurs where the chromosomes replicates forming two identical copies of DNA.
That is, the cell now has 92 chromosomes which is enough DNA for two cells.
Therefore the statement below about interphase is correct.
In Interphase the chromosomes have duplicated, indicating that there will be enough genetic material to separate into daughter cells capable of reproduction.In the prophase, the mitotic apparatus appears; this consists of two centrioles separated by the mitotic spindle which is formed from microtubules.
The formation of these mitotic spindle fibres indicates that the chromosomes will be split evenly.
Therefore the statement below about prophase is correct.
In Prophase (Prophase I and II of meiosis) the spindles form, indicating that the chromosomes will be split evenly, and the daughter cells will receive the appropriate amount of genetic material.Learn more here:
