Which of the following can limit the growth of a population of organisms?
Group of answer choices
A. Neither the number or predators nor diseases can limit the growth of a population of organisms.
B. The number of predators can limit the growth of a population of organisms, but diseases cannot.
C. Both the number of predators and diseases can limit the growth of a population of organisms.
D. Diseases can limit the growth of a population of organisms, but the number of predators cannot.
Answer:
c
Explanation:
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.

single-celled organisms are able to maintain homeostasis even though they lack higher levels of organization such as organs and organ systems because...
Answer:
Because cells maintain homeostasis despite the amount.
Explanation:
When a change occurs in an animal’s environment, an adjustment must be made so that the internal environment of the body and cells remains stable. The receptor that senses the change in the environment is part of a feedback mechanism. The stimulus—temperature, glucose, or calcium levels—is detected by the receptor. The receptor sends information to a control center, often the brain, which relays appropriate signals to an effector organ that is able to cause an appropriate change, either up or down, depending on the information the sensor was sending.
Single-celled organisms are able to maintain homeostasis even though they lack higher levels of organization such as organs and organ systems because - all cell structures work together to maintain homeostasis.
Unicellular organisms like bacteria have various ways of maintaining homeostasis. There are various cellular structures and particles to maintain homeostasis. For example,
Bacteria also have sensors, a protein molecule, that sense and respond to toxic levels of heavy metals in the environment and also help regulate beneficial metal ions.Unicellular such as bacteria can control the lipid composition in their plasma membranes to regulate the permeability for substances to move in or out.Bacteria and paramecium are unicellular organisms that use contractile vacuoles to control the amount of water inside of them.Thus, Single-celled organisms are able to maintain homeostasis even though they lack higher levels of organization such as organs and organ systems because - all cell structures work together to maintain homeostasis.

Here are four options that would ensure an experiment is replicable and valid: Control group, Randomization, Double-blind design, Replication that are present in option A, B, C, and D.
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.
Hence, here are four options that would ensure an experiment is replicable and valid: Control group, Randomization, Double-blind design, Replication that are present in option A, B, C, and D.

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
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:

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?
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.
