(give 4 enzymes examples-Key on tge types of nutrients we process-carbohydrates, lipids[Fats], & proteins
Answers
Answer:
The Role of Enzymes in the Digestive System. Chemical digestion could not take place without the help of digestive enzymes. An enzyme is a protein that speeds up chemical reactions in the body. Digestive enzymes speed up chemical reactions that break down large food molecules into small molecules.
Role of the protease enzyme:
Protease refers to a group of enzymes whose catalytic function is to hydrolyze peptide bonds of proteins. They are also called proteolytic enzymes or proteinases. ... For example, in the small intestine, proteases digest dietary proteins to allow absorption of amino acids.
Location of production of the protease enzyme: Protease is produced in the stomach, pancreas, and small intestine. Most of the chemical reactions occur in the stomach and small intestine. In the stomach, pepsin is the main digestive enzyme attacking proteins. Several other pancreatic enzymes go to work when protein molecules reach the small intestine.
Where they enter the alimentary canal?
Proteases are released by the pancreas into the proximal small intestine, where they mix with proteins already denatured by gastric secretions and break them down into amino acids, the building blocks of protein, which will eventually be absorbed and used throughout the body.
pH range in which they work best: In pancreatic protease, it works best I.e, in the pH range of 7.5-8.0

Answer:
C) Cladograms are detail-oriented and do not provide a useful understanding of evolutionary relationships.
Explanation:
Cladograms are not necessarily helpful because sometimes organisms with similar characteristics can emerge based on environmental factors and not necessarily from the same ancestors. This is the idea of convergent evolution where two species can have same characteristics but are not related at all and since, cladograms are based on depicting evolutionary relationship based on similar characteristics, it fails to take into account the effects of convergent evolution where same characteristics does not necessarily mean same ancestor.
Cladogram is not an evolutionary tree so it does not show an evolutionary relationship or kinship among ancestors and descendants

Doctors often count the amount of neutrophils in a person's blood to see if he or she has a certain illness. Why would this be a useful test?
Answers
Answer:
Because they will increase or decrease in specific diseases which, along with other cell counts, would help narrow down the illness.
Explanation:
Lymphocytes one of the subtypes of immune cells present mainly in the lymph of the lymphatic system. They are composed of 3 types of cells
T-Cells
B-Cells
Natural-Killer (NK) Cells
T-Cells and B-Cells function as detection cells. Where they recognize & mark "non-self cells" or "infected self cells" as potential threat to the body and initiates or signals for their immediate elimination.
NK cells on the other hand, will recognize & eliminate "non-self cells" or "infected self cells" directly.
These cells will mostly respond to viral infections or tumor cells. Thus, their blood levels will increase mostly in these situations.
This means that if the patient is suffering from a fever or a sore throat, then the doctor can conclude whether this infection is caused by a viral or bacterial infection depending on how high Lymphocytes increases in the CBC test.
However, it should be noted that it is not used as a "sole" test but one of the tests to help narrow-down and pin-point the illness.

Answers
Answer:
I think it's because it will decay and be soil and soil is biotic factor
A dead tree would still be a biotic factor, even though it is no longer alive because biotic factors include living organisms and the remains of the living organisms.
What are biotic factors?Biotic factors are those factors that are living and growing and reproducing. The living organism that were once lived are also comes sunder biotic factors.
A dead tree mean a dried tree that still has wood and dry leave. The wood will decompose or will use in burning purpose. The dead tree will still consider as a biotic factor because it was once alive.
Thus, Even if it is no longer alive, a dead tree would still count as a biotic factor because biotic factors comprise both living species and their remains.

Hanson is designing an experiment to test the porosity of a soil sample. His experiment involves the following:
Place the soil sample in a water-tight container.
Slowly pour water into the container.
Measure the volume of water that the soil absorbs.
Which of the following would improve Hanson's experiment?
A.
if he measured the volume of the soil beforehand
B.
if he measured the mass of the soil beforehand
C.
if he measured the porosity of the water beforehand
D.
if he measured the mass of the water beforehand
Answers
Answer:
A
Explanation:
If he measured the volume of the soil beforehand.
If Hanson measured the mass of the soil beforehand and then Slowly pour water into the container and measure the volume of water that the soil absorbs. This would improve Hanson's Soil porosity experiment.
What is porosity of soil?The percentage of total soil volume taken up by pore space is known as soil porosity.The porosity of a soil is essential for a variety of reasons. The fact that soil pores contain the groundwater that many of us drink is one of the main reasons. The oxygen contained within these pore spaces is another significant feature of soil porosity. Because all plants require oxygen to breathe, a well-aerated soil is essential for agricultural production.Soil particle texture, soil structure, soil compaction, and the amount of organic material in the soil all influence its porosity. A fine-textured soil can hold more water than a coarse-textured soil.How will measuring the mass of soil beforehand will improve Hanson's experiment?when the mass of soil is measured prior to the experiment, it will contain a certain mass (M1) which will be lesser than the one gained after the experiment.After water is poured over the soil, the mass (M2) of the soil will increase due to absorption of the volume of water.the total water absorbed can be calculated by subtracting M2 from M1 which will give the total volume of water absorbed by the soil.other options are incorrect:
if he measured the volume of the soil beforehand soil is measured in mass and liquids like water have a volumeif he measured the porosity of the water beforehand, water does not have porosityif he measured the mass of the water beforehand, water does not have mass it has volume. measuring volume of water before experiment is of no use.learn more about Soil porosity here:
