Answer:
So i had these notes from a couple of days ago and I’d like to help u out
Explanation:
Photosynthesis
Carbon dioxide enters through the leaf which contains small pours called stomata. The carbon dioxide then enters the cells of the leaf.
Inside the cell carbon dioxide diffuses into the chloroplasts. Where photosynthesis takes place
Chloroplasts use energy from sunlight to transform carbon dioxide and water into sugar and oxygen.
The light reactions
Inside chloroplasts there are these flat membranous sacs called thylakoids.
Thylakoids are the place were light energy is converted into chemical energy in the first phase of photosynthesis the light reactions.
Photosystems
Photosystems are large complexes of proteins and chlorophyll (capture light energy)
Electron transport chain
This chain connects the two photosystems.
Electron carrier
These shuttle (transport that is mainly between 2 things going back and forth) electrons from one photosystem to another
Photosystem
One of the photosystems are used to absorb energy which then excites the electrons that then enter the electron transport chain. These electrons are replaced with electrons stripped from water creating oxygen as a byproduct.
The electrons on the chain
The energised electrons are flowing down the electron transport chain releasing energy that is used to pump hydrogen ions
Hydrogen ions
An atom or molecule that has a net electrical charge due to the loss of one loss or one gained electron.
The electrons on the chain
As the hydrogen ions get pumped out they are then absorbed into the thylakoids
In the photosystem on the right light energy excites electrons and this time the electrons are captured by an electron carrier molecule also known as NADPH
The high concentration of hydrogen ions inside the thylakoid powers ATP synthase producing ATPS the light reactions in the thylakoid have produced two products, ATP and NADPH.
Those two products then power the production of sugar in the Calvin cycle
THE CALVIN CYCLE (C3 Cycle)
The Calvin cycle takes place outside the thylakoids in the stroma (the thick fluid of the chloroplast).
At the beginning of the cycle
carbon dioxide molecules combine with molecules called rubp the resulting molecules go through a series of reactions powered by ATP and NADPH from the light reactions sugar molecules known as g3ps are produced.
G3ps
Most of the g3ps molecules are rearranged back into rubp’s that begin the calving cycle again.
The important product
Then some of the left over g3ps is the remaining g3p sugar, some g3ps are used to build glucose which can then combine into starch or even cellulose
Bits of left over g3ps are also able to break down by cellular respiration, which uses oxygen in the plants own mitochondria, this generates ATPS that can power other work of the plant.
The left overs
Excess oxygen diffuses out of the leaf through the pores while more carbon dioxide goes into the leaf pores.

Why do villi secrete mucus for protection?
The intestinal mucus is an efficient system for protecting the epithelium from bacteria by promoting their clearance and separating them from the epithelial cells, thereby inhabiting inflammation and infection
hope it helps!
Answer:
it protects epithelium from harmful bacteria.thereby inhibiting inflammation and infection.

G proteins are enzymes that bind and hydrolyze GTP to GDP. They are regulated by associated proteins that induce the binding of GTP and are called ____________ and that induce the hydrolysis of GTP to GDP and are called ___________.
Answer:
Explanation:
(A) Heterotrimeric G-proteins are composed of three distinct subunits (α, β, and γ). Receptor activation causes the binding of the G-protein and the α subunit to exchange GDP for GTP, leading (more...) The second class of GTP-binding proteins are monomeric G-proteins (also called small G-proteins).
The diagram shows a simplified version of how the blood moves around the body of an animal. Is the blood at point D oxygenated or deoxygenated?
Answer:
oxygenated
hope u got your answer
In the given diagram, point D is oxygenated blood, as it carries oxygen from heart to cells.
What is heart?The main organ of your cardiovascular system, a network of blood vessels that pumps blood throughout your body, is your heart.
It also collaborates with other bodily systems to regulate your heart rate and blood pressure. Your family history, personal health history, and lifestyle all have an impact on how well your heart functions.
The heart is located between the two lungs, slightly to the left of center, behind the breastbone in humans. It is supported by the diaphragm, the muscular wall that separates the chest from the abdominal cavity.
It's the muscle at the heart of your circulatory system that pumps blood throughout your body as your heart beats. This blood transports oxygen and nutrients to all parts of your body while removing waste and carbon dioxide.
Here, the red vessels are arteries while blue vessel is vein, arteries always carries oxygenated blood and vein carries deoxygenated blood.
Thus, the point D carries oxygenated blood.

records a statement that will either be
proven or disproven by the experiment.
Each member of the group carefully watches
as the experiment proceeds. One group
member writes down the comments of the
group as they call out what they see.
After the experiment is complete, the group
discusses their observations. They review their
notes and create a graph that shows the
results of the experiment. The group
discusses what these findings might mean.
Now that the group has decided on a

How does seed become dormant?
Answer:
Seeds may be dormant because the seed coat prevents germination, or because the embryo - by itself or together with chemicals - inhibits germination. Seed coats render seeds dormant if: their hardness prevents the embryo from expanding. impermeability to water stops development.
