Explain why when you exercise your heart rate change?
(less than 20 words)
Answer:
when you are exercising the muscles need extra oxygen,for this oxygen to be supplied quick the heart pumps faster which makes a quicker pulse.
I hope this helps
Answer:
During exercise, your body may need three or four times your normal cardiac output, because your muscles need more oxygen when you exert yourself. During exercise, your heart typically beats faster so that more blood gets out to your body.Your heart can also increase its stroke volume by pumping more forcefully or increasing the amount of blood that fills the left ventricle before it pumps. Generally speaking, your heart beats both faster and stronger to increase cardiac output during exercise.

1. What changes occurred in the diameter of the onion rings that were immersed in the distilled
werter and concentrated sucrose solution? State the difference in the concentration of water
molecules in the onion cells and the solutions.
(a) Distilled water
(b) Concentrated sucrose solution
2. Explain why the changes occurred in the onion rings immersed in:
(a) distilled water;
(b) concentrated sucrose solution.
In this case, it is important to have into account the properties of hypertonic (sucrose) and hypotonic (distilled water) solutions:
Sucrose solution (higher concentration of water molecules in the onion cells) >> red onion cells will shrink >> smaller diameter.Distilled water (higher concentration of water molecules in the surrounding solution) >> red onion cells will become turgid >> higher diameterOsmosis refers to the movement of a solvent (usually water molecules) across semipermeable biological membranes, which occurs from a region of higher concentration to a region of lower concentration. There are three classes of solutions that have different effects on cells due to the process of osmosis:In a hypotonic solution, the cells will become turgidIn an isotonic solution, the cells will become flaccidIn a hypertonic solution, the cells will shrink (plasmolysis)When plant cells are placed into a hypertonic solution where there is a greater concentration of solute outside the cells (as in this case sucrose solution), water molecules will move from inside the cells to outside the cells, thereby cells will shrink due to water lossMoreover, when plant cells are placed into a hypotonic solution that is diluted in comparison to the content of the cell (as in this case plant cells placed in distilled water) water molecules will move from outside the cells to inside the cells, thereby cells will become turgid.Learn more about this topic here:

The conversion of glucose to glucose 6-phosphate is an enzyme-catalyzed reaction. During this reaction, the enzyme hexokinase folds around the substrates to bring reactive side chains from the active site into alignment with the substrates. This change in hexokinase is an example of
Answer:
Induced fit
Explanation:
Induced fit (IF) is a model used to understand enzyme-substrate interactions, which can be considered as a development of the classical lock-and-key model. This model (IF) was proposed by Daniel Koshland (1958) in order to understand protein conformational changes during the binding process. The model states that the active site of the enzyme, i.e., the region where the substrate binds and catalyzes the reaction, is reshaped when it binds with its substrate in order to improve the fit. The IF model assumes that the active site of the enzyme is flexible and is capable of changing its shape until the substrate is completely bound.

different between dominant character and recessive character
Dominant character:are always expressed when the connected allele is dominant,even if only one copy of the dominant trait exits.
Recessive character:are expressed only if both the connected allele are recessive.
Answer:
Dominant and recessive traits exist when a trait has two different forms at the gene level. The trait that first appears or is visibly expressed in the organism is called the dominant trait. The trait that is present at the gene level but is masked and does not show itself in the organism is called the recessive trait.
Explanation:
If some traits are absent or not expressed, but found in the parent, then the allele is said to be recessive.
Difference Between Recessive and Dominant Traits
DOMINANT
Dominant Trait Recessive Trait
Dominant allele is denoted by a capital letter
RECESSIVE
Recessive allele is denoted by a small letter

How do the outer layers of cells on the underside of a leaf work to gather carbon dioxide?
The outer layers of cells on the underside of a leaf work to gather carbon dioxide by the utilization of stomata.
What are Stomata?Stomata may be defined as the presence of tiny pores in the epidermis of the leaf or stem of the plant. The fundamental function of this structure is to regulate the amount of gas exchange.
A massive amount of gaseous exchange takes place in the leaves through these pores for the purpose of photosynthesis.
The opening and closing of these stomata are regulated by the guard cells. In order to prevent water loss through such pores, plants are required to close such pores during mid-day.
Therefore, the outer layers of cells on the underside of a leaf work to gather carbon dioxide by the utilization of stomata.

How do animals and people cause weathering?
How do plants cause weathering ?
Answer:
Plants can cause mechanical and chemical weathering
Explanation:
Plants can cause mechanical and chemical weathering. When plants cause mechanical weathering, their roots grow into rocks and crack them.It can also happen in streets or sidewalks. When plants cause chemical weathering, there roots release acid or other chemicals, onto rocks, which then forms cracks, and breaks apart.
Animal and plant mobility is a factor in biological weathering, for instance, a plant may grow in a gap in a rock and, as its roots spread, cause the fracture to expand.
What is the cause of weathering?A rabbit may also burrow into a crack in a rock, making it wider and eventually separating the rock.
Animals and plants can act as mechanical weathering agents. In dirt that has gathered in fractured rock, a tree seed may emerge. The fissures get wider as the roots spread out, finally shattering the rock into pieces.
Even big rocks might get dislodged by trees over time, rocks are broken down by plants like moss that absorb their minerals.
Therefore, holding onto soil and rocks is another way that plant roots cause weathering, and might stop erosion.

C.Carbon cycle
D.Phosphorus cycle
water cycle............
The following is NOT of the major biogeochemical cycles D.Phosphorus cycle is D.Phosphorus cycle.
What is the difference between Carbon cycle and Phosphorus cycle?The major distinction among carbon and phosphorus cycle is that carbon cycle interacts with the environment while phosphorus cycle does now no longer engage with the environment. Therefore, the carbon cycle is a sort of gaseous biking while the phosphorus biking is a sort of sedimentary rocks.
As in comparison to nitrates & different macro elements, decomposers take longer time to decompose any lifeless biota into phosphates. Decomposers are organisms mainly a soil bacterium, fungus, or invertebrate, that decompose natural material. These are the motives for phosphorus cycle being the slowest biogeochemical cycle.
