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.

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.

Include where they are produced, where they enter the alimentary canal, pH range in which they work best, the types of molecules they chemically digest and what products the chemical breakdownz form. (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.

Chosen enzyme: Protease

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

What is an experiment?

Replicability and validity are important concepts in experimental research. Replicability refers to the ability to repeat an experiment using the same methods and obtain similar results. Validity refers to the extent to which an experiment measures what it is intended to measure. To ensure that an experiment is replicable and valid, researchers must take several steps. One important step is to include a control group in the experiment. A control group is a group of participants that does not receive any treatment or intervention.

Hope this helps..

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

population growth is entirely dependent on both of these

The one can limit the growth of a population of organisms is the number of predators, and diseases can limit the growth of a population of organisms. The correct option is c.

What is the population?

The amount of people in a population is referred to as its population size. The average number of people per unit of area or volume is referred to as population density. This is a term that refers to the human population that lives in a specific geographical area.

The map depicts the concentration of the human population on the planet from all the continents depicted. A population pyramid is a diagram that depicts the total number of organisms that are successfully living and interacting with one another in a specific location at a given time.

As a result, the population pyramid predicts that the population is increasing.

Therefore, the correct option is C. Both the number of predators and diseases can limit the growth of a population of organisms.
