Answer:
glucose carbohydrates
Explanation:
As an immediate source of energy, glucose is broken down during the process of cellular respiration, which produces ATP, the energy currency of the cell. Glucose or blood sugar, is the main source of energy for your body's cells, tissues, and organs.
Somebody help me please
Answer:
I think its C... they change the speed.
Explanation:
"Enzymes are catalyst that speeds up the rate of biochemical reaction in living organism. They are protein in nature and they are involved in every process that take place in living organisms such as breaking down of food to building up of protein. In living organism, enzymes speed up the rate of chemical reaction by lowering the activation energy thereby bringing the reactants close to each other and weaken there chemical bonds which will enable the reactions to be faster".
QUICK!!! What is the purpose of the Cell membrane?
Answer:
For all cells in general the cell membrane holds everything (organelles) inside. it's like animals having skin. I mean can you imagine what it would be like to not have any skin.
Plant cells;
For this type of cell the membrane also gives the cell a certain structure and deribility.
Answer:
The cell membrane is a biological membrane that separates the interior of all cells from the outside environment which protects the cell from it's environment.

why is radiation a unique form of thermal energy transfer?
Answer:
The radiation occurs at all temperatures, with the rate of emission increasing with the temperature. Figure 3.1. Heat transfer by thermal radiation between two bodies. Unlike conduction and convection, heat transfer by thermal radiation does not necessarily need a material medium for the energy transfer.
Explanation:
none
Radiation is the electromagnetic transfer of heat energy through space. The majority of the electromagnetic radiation emitted by the sun is invisible to the human eye.
What is radiation?Radiation is energy that travels through space at the speed of light from a source.
This energy is associated with an electric and magnetic field, and it has wave-like properties. Radiation is also known as "electromagnetic waves."
Radiation is a mutagen that can eventually cause cancer. Radiation can either kill cells or damage their DNA, impairing their ability to reproduce and eventually leading to cancer.
High energy particles pass through your body when radiation is present.
Because radiation (primarily electromagnetic waves) can transfer energy even through a vacuum, no mas is required.
Other types of energy transfer involve the transmission of vibrational motion from one matter molecule to the next.
Thus, radiation is a unique form of thermal energy transfer.

explain how facilitated diffusion assists in osmosis in cells
Answer:
Facilitated diffusion is diffusion using carrier or channel proteins in the cell membrane that assist in the movement of molecules across a concentration gradient. The third type of movement is known as osmosis, or the movement of water to equalize solute concentration.

The most important difference between primary cells and secondary cells is Select only the best answer: primary cells exhibit a reduction in potential as they run down secondary cells have more than two working electrodes only primary cells have a salt bridge secondary cells are rechargeable primary cells use chemical energy directly, while secondary cells convert energy to work before producing electricity
Hi there! This question is a bit confusing.
Primary cells more of have one "star" quality; they are not rechargable. Think of them like a battery in a TV remote! You replace them, they can't recharge.
Secandary cells, though, can be electrically recharged! Like your phone battery, plug it in and a few hours later, full battery.
Your answer would be "Secondary cells are rechargable"

How can some large molecules and charged ions get through the cell membrane?
Answer:
In cells, some molecules can move down their concentration gradients by crossing the lipid portion of the membrane directly, while others must pass through membrane proteins in a process called facilitated diffusion.
Some large molecules and charged ions get through the cell membrane as
a result of osmosis, diffusion, facilitated diffusion etc.
Molecules get through the cell membrane through diffusion which is the
movement of substances from a region of higher concentration to a region
of lower concentration.
Facilitated diffusion is the same with diffusion but it makes use of a
substance for transport.

Answer:
7) the environment is hypotonic because it is less concentrated than the inside of the cell
8.)the mass would decrease because the stuff inside the cell (which is more concentrated in comparison) would diffuse across the cell membrane into the environment in order to maintain equilibrium
9.) Diffusion in order to maintain equilibrium (moving things across a barrier from a more concentrated area to a less concentrated area in order to have an equal concentration on each side) does not require energy. However, moving matter out of the cell in Diagram C would require energy because it involves moving mass from a less concentrated area to a more concentrated area.

Should water h20 be included in the model as a reactant or a product
Answer:
The water should be omitted as a reactant or product to have a well-balanced equation only if the water reacts as a solvent.
Explanation:
The water acts as a pure liquid and the increase of concentration of pure liquid is impossible. So, it is of no use when it acts as a solvent. As a product form water can be obtained as a liquid or gaseous substance. Their ability can increase the supply of hydrogen or oxygen to the reaction. When it is used as a main reactant it should be included.
As a role of solvent, it has no use in the chemical reaction. It has insignificant values as a role of solvent so it should be formatted while having the well-balanced equation. There are a lot of examples in which water is not included in the chemical reaction.

Q.1: The building in this photo was damaged during an earthquake.
Can we feel plate movement when there isn’t an earthquake?
Q.2: How far do you think a plate can move in one day?
Q.3:How far do you think a plate can move in one year?
When considering plate tectonics and the rate at which tectonic plates move, we can say that daily, the plates will move fractions of a millimeter, which can result in up to a few centimeters yearly, which is why we don't feel this movement when there isn't an earthquake.
Plate tectonics refers to the movements of large-scale plates that make up the earth's lithosphere. Despite their massive size, and very beneficial to us, these plates move very slowly and gradually. The plates can move at rates up to half a millimeter per day, which will result in about 14cm yearly.
This seemingly slow speed is actually among the highest number recorded for plate movements, most in fact will move much slower than that. It is due to this very slow movement speed that we do not feel the movement of plate tectonics when there is no earthquake.

What is excretion and egestion
Answer:
Explanation: Excretion and Egestion Difference
Excretion is the process where an organism excretes the byproduct of a metabolic process using the different cellular and organ functions. Egestion, on the other hand, is the term associated with the excretion or elimination of undigested food from the digestive system of an animal.
Answer:
Basically egestion is when undigested food becomes waste and comes of out the body through the anus, and excretion is when your body removes toxic and waste material and excess products from organisms.
