Answer:
DIFFUSION
Explanation:
Water, carbon dioxide, and oxygen are among the few simple molecules that can cross the cell membrane by diffusion (or a type of diffusion known as osmosis ). Diffusion is one principle method of movement of substances within cells, as well as the method for essential small molecules to cross the cell membrane.

What are the products for a single pyruvate molecule in the Krebs Cycle?
Answer:
In the conversion of pyruvate to acetyl CoA, each pyruvate molecule loses one carbon atom with the release of carbon dioxide. During the breakdown of pyruvate, electrons are transferred to NAD+ to produce NADH, which will be used by the cell to produce ATP.

Chromosome pair 23 are the sex chromosomes and are responsible for determining the gender of a human. The large chromosome is an X chromosome, and the small chromosome is the Y chromosome. If there are two X’s, then the individual is a female. If there is an X and Y, then the individual is a male.
Answer:
This is true.
Explanation:
More commonly, an X chromosome will die and get replaced by a Y chromosome (all humans start off as females). When this occurs, the substitute Y chromosome causes changes in the zygote to occur; they begin developing male genitalia (i.e. penises, testicles, prostates, etc.).

when do birds use their teeth????
Answer:
to eat worms
Explanation:
Answer:
Birds do not have teeth, however...Explanation:
[tex]--------------------------------------------[/tex]
According to The Cornell Lab, "Birds do not have teeth, however, they may have ridges on their bills that help them grip food, but this does not count as teeth. So what about birds that have “tooth” in their name, like Double-toothed Kite? Some birds of prey have a sharp ridge or “tomial tooth” on the bill that they use to bite into their prey when subduing it. But these modifications to the bill surface are not considered the same thing as individualized teeth seen in other animals."

The cell stops being able to allow things into or out of its body. It starves. The
organelle that must be broken is the________
Answer:
The correct answer is - cell membrane.
Explanation:
Cell membrane or plasma membrane is the outer structure that enclosed the cell-matrix and cell organelles and acts as a barrier to the substances and things to move in or out of the cell and allows only specific substances and molecules to move in and out of the cell.
If the cell membrane is not performing its function properly it might result in blocking the various nutrients and other essential molecules to move in and metabolic substances to move out of the cell.

Complete the half reactions for the cell shown here, and show the shorthand notation for the cell by dragging labels to the correct position. the electrode on the left is the anode, and the one on the right is the cathode.
The question is incomplete, the complete question is;
complete the half reactions for the cell shown here and show the shorthand notation for the cell by dragging labels to the correct position. The electrode on the left is the anode, and the one on the right is the cathode.
in the left side there is a solution of Pbcl2(s) and it contains the elctrode pb and on the right side there is solution of AgCl(S) which contains the electrode Ag. There is inverted glass tube with Kcl (aq) on the left and and Kcl(aq) on the right.
Anode half-reaction:
Blank + 2Cl^- equilibrium arrow yields Blank + 2e^-
Cathode half reaction:
Blank +2e^- equlibriums arrow yields Blank + 2Cl^-
Shorthand notation: Please provide.
Answer:
Explanation:
Let us remember that oxidation occurs at the anode while reduction occurs at the cathode. This will guide our work here. The Pb(s)/Pb^2+(aq) is the anode while the Ag^+(aq)/Ag(s) is the cathode
Anode half-reaction:
Pb(s) + 2Cl^- ⇄ Pb^2+(aq) + 2e^-
Cathode half reaction:
2Ag^+(aq) + 2e^- ⇄ 2Ag(s) + 2Cl^-
Overall reaction equation;
Pb(s) + 2Ag^+(aq) ⇄ Pb^2+(aq) + 2Ag(s)
Shorthand notation;
Pb(s)/Pb^2+(aq)//Ag^+(aq)/Ag(s)

Identify the tonicity of the solution surrounding the cell.
Answer:
Hypertonic
Explanation:
Hypertonic solutions have less water ( and more solute such as salt or sugar ) than a cell. Seawater is hypertonic. If you place an animal or a plant cell in a hypertonic solution, the cell shrinks, because it loses water ( water moves from a higher concentration inside the cell to a lower concentration outside ).
Native bumblebees live in grasslands and consume pollen and nectar from flowers. The bumblebees carry pollen from one plant to another. The bees pollinate most but not all the flowers in their habitat. Amphibians and insects, such as dragonflies, eat bumblebees.
A local resident sets up honeybee hives in the habitat of the bumblebees. Honeybees are a nonnative species that eat the same food as the bumblebees. Food now becomes a limiting factor for the bumblebees.
How might the populations of flowers, bumblebees, and dragonflies change after the introduction of honeybees to the ecosystem?
Group of answer choices
Flowers will increase, bumblebees will decrease, and dragonflies will decrease in population size.
Flowers will decrease, bumblebees will decrease, and dragonflies will decrease in population size.
Flowers will increase, bumblebees will increase, and dragonflies will increase in population size.
Flowers will decrease, bumblebees will decrease, and dragonflies will increase in population size
Answer:
i think it's A. why? because bumblebees pollinate flowers making more grow but dragonflies EAT the bees so they'll decrease.

Describe how a solid rock in the lower level of the crust could become a molten rock.
PLS HELP I WILL MARK BRAINLIEST
Answer:
The higher the pressure on anything, the hotter it will get. The hotter a rock gets, the more possibility that it will have to melt.
So you're out the base of the crust, with any kilometers of crust above you, and that's a lot of pressure. Then take into account that you have thousands of degrees of heat coming from the mantle-core boundary, and directly from radioactive decay within the mantle, which only adds to the temperature.
The net result is like melting a stick of butter. It's very easy to do without a lot of energy -- since Earth is a massive ball of thermal energy, then well... it's easy to do.

Osmosis requires energy
True
Or
False
Answer:
Diffusion and osmosis don't require the cell to expend any of its own energy, as they are passive processes. As we know both are passive processes and yet (in basic, short terms) diffusion is higher to lower and osmosis is lower to higher, so movement to concentration doesn't determine whether it is active or passive.
