thats true brooooooooooooooooo
Answer:
True statements:
Both plant and animal cells have nucleus
Vacuoles store nutrients, water, and waste in animal cells
Explanation:
These are the answers because
1) The plant cell contains a large vacuole. Therefore, the first statement is false.
2) Both plant and animal cells do have a nucleus because they are eukaryotic.
3) Vacuoles are known as "storage bins" to the cell. Vacuoles store nutrients, water, and waste for a cell to survive. They store waste products so the rest of the cell is protected from contamination.

suppose your cells continue to help heal the scrape that resulted from the falling off your bike.what might happen if the cell cycle did not go into a rest phase explain.
Answers
Answer:
If the cell cycle did not go into a rest phase, what would occur would be uncontrolled cell growth. This could lead to tumor formation and cancer.
When the cell cycle fails to go into a rest phase than formation of tumor or cancer may take place.
• Generally, the cells in humans grow and proliferate to produce new cells as the body requires then. In case, when the cells become damaged or become old, they perish, and formation of novel cells takes place.
• However, the order may break, and the damaged or abnormal cells grow and proliferate when they should not, that is, the cells fails to go into the resting phase.
• These cells may give rise to formation of tumors, that is, the lumps of tissue, these tumors can be non-cancerous, that is, benign or can be cancerous, that is, malign.
Thus, the cells when failing to go into the resting phase may turn into tumors or cancerous cells.

a. More seeds grow with more light.
b More seeds grow with less light.
C. The seeds grow faster with more light.
d Tinht has no effect on seed growth.
Answers
Answer:
The 2 graphs are pretty much showing the same effects on the dependent variable, so I would say that light has no effect on seed growth.
On the other hand, just by thinking logically, Seeds are usually underground before germination, so light wouldn't really affect them much.
So, light wouldn't really affect them

What is Isotonic solution??
Answers
Answer:
An isotonic solution is one that has the same osmolarity, or solute concentration, as another solution. If these two solutions are separated by a semipermeable membrane, water will flow in equal parts out of each solution and into the other.
Answer:Isotonic solutions contain equal concentrations of impermeable solutes on either side of the membrane and so the cell neither swells nor shrinks.

Answers
Answer:
Enzymes speed up the rate of a chemical reaction to help support life.But in Biochemical reactions , enzymes lower the activation energy of chemical reactions.Note ;Activation energy is the energy needed to start a chemical reactio
Explanation:
Digestive enzymes which are secreted in the acidic environment which has a low pH of the stomach help break down proteins into smaller molecules. The main digestive enzyme in the stomach is pepsin.
Enzymes accelerate the velocity of chemical reactions without consuming them or causing them to change permanently inside the cell.
What effect of enzyme on chemical reaction inside cells?
By lowering the activation energy and consequently raising the rate of reaction, enzymes (and other catalysts) work.
Since both directions must travel through the same transition state, the increased rate is the same in both the forward and reverse directions.
Cellular chemical reactions are accelerated (catalyzed) by enzymes. More precisely, they lower the barrier that must be crossed in order for the targeted reaction to occur.
By adhering to a substrate—an additional substance—they accomplish this.
Therefore, enzyme have effect on a chemical reaction within a cell.

Answers
Answer:its D- vacuoles
Explanation: i did further research cause the other answer is bs
Vacuoles are organelles found both in plant and animal cells. However, these organelles are greatly reduced in animal cells (Option D).
Vacuoles are organelles that function to store substances (.e., food or nutrients, waste products, etc) both in plant and animal cells.
These organelles are filled with water and contain both inorganic (e.g., salts) and organic molecules (e.g., enzymes).
In animal cells, vacuoles are much smaller than in plant cells and they are often used to store materials and/or transport substances.
In conclusion, the vacuoles are greatly reduced in animal cells (Option D).

The Gulf Stream is an ocean current of warm water that flows from the Caribbean Sea up the eastern coast of North America before crossing over to the British Isles. The current brings warm water and air northward. Scientists are concerned that global warming will cause polar ice to melt and form a cold water current that blocks the Gulf Stream. Infer possible climatic effects resulting from substantial quantities of northern polar ice melting.
Answers
Answer:
Explanation:
Due to rise temperature leading to melting of ice more water flows to the seas from glacies and ice caps increasing the volume of water in the ocean. This has lead to increase in average global sea level between four and eight inches.
It leads to salt water intruding into freshwater this affect sources of drinking water and makes raising crops problematic.
It leads to increase in population on the coast as people moved far away from the shore due to erosion.

Explanation:
What the RxN tells me is that we take in sugar as well as oxygen, combine them together and react, and in turn produce carbon dioxide, water, and energy.
This makes sense, because we eat food and breathe in oxygen, so those are our reactants. When we exhale, we breathe out carbon dioxide and we go use the restroom to get rid of excess H₂O. The energy produced is used for our bodily movements.
