Secondary Consumers
(ex: snake)
Primary Consumers
(ex: grasshopper)
Producers
(ex: grass)
If a pesticide is released into the environment that kills most of the grasshoppers, which of the following is most likely to occur?
OA.
an increase in population for all organisms
ОВ.
a decrease in the number of snakes
C
an increase in the number of hawks
D
a decrease in the amount of grass
Answer:
It should be A. If the pesticide is released, then they die, and the consumers of the grasshopper (snake) dies due to no grasshoppers, then the animal that consumes the other animal (hawk eats snake) that eats the grasshopper will die because there aren't enough of that animal for it to eat. the only thing that lives is the grass.
Sorry if I'm wrong, but i hope it helps.
Answer:
It's actually B, "a decrease in the number of snakes"

Explanation:
I Took The Test
The statement 'scientists used radioactive dating to study the age of material from the moon and Earth' best explains how scientists confirmed that the moon formed around the same time as Earth.
What is radioactive dating?Radioactive dating is a well-known technique used to date the age of specific rocks (in this case, moon rocks).
Radioactive dating uses the average life of radioactive isotopes to determine the age of a particular rock.
Radioactive isotopes used in radioactive dating may include, among others, Carbon-14 and Hydrogen-3 (tritium).
In conclusion, the statement 'scientists used radioactive dating to study the age of material from the moon and Earth' best explains how scientists confirmed that the moon formed around the same time as Earth.

briefly explain the relationship between cells, organs and tissues
Answer/Explanation:
Cells of a similar type are organized together to make tissues. Different types of tisues come together to perform a similar function as part of organs.
For example, take the organ the stomach. There are various tissues that make up the stomach, including, for example, mucosa, and muscle tissue.
The mucosa tissue of the stomach is made up of secretory cells such as parietal cells, which secrete hydrochloric acid, and foveolar cells which produce mucus that protects the lining of the stomach.

Explain the contribution of antigenic determinant in false negative and false positive tests
Answer:
Contribution of antigenic determinant in false negative -: Popular causes of false-positive ELISA include: flu vaccine administration, presence of HLA-DR antibodies in women with multigravity, presence of rheumatoid factor. Contribution of antigenic determinant in false positive tests -: Positive RPR exam, hypergammaglobulinemia and autoimmune hepatitis (e.g. multiple myeloma).Explanation:
Much attention has been paid to the specificity and sensitivity of this assay since regular ELISA screening of blood donors for anti-HIV antibodies was implemented. It was found that inadequate coating of the microtitre plates with HIV-antigen could lead to false negative results. It is important that the ELISA test kit manufacturers use control systems that guarantee adequate antigen coating.
7. Why are adult sponges said to be sessile animals? |

Runners only have enough stored ATP in their muscle cells to run for about five seconds. Which answer correctly explains how the runner's body adjusts to the longer distance, for example, a marathon (42.1 km)?
Answer Options:
A: The runner's body will convert stored fat molecules into energy.
B: The runner's body will create the needed energy by breaking down proteins.
C: The runner's body will supply the needed energy by producing starch.
D: The runner's body will produce the energy by activating the Golgi apparatus.
Answer:
A: The runner's body will convert stored fat molecules into energy.
Explanation:
When the body needs energy to power cells, it uses ATP. ATP is generated by cellular respiration, which involves the breakdown of (usually) sugars by aerobic respiration.
If you exercise for a longer period such as during long distance running, your body will use more fat and less glucose in an attempt to conserve the limited glucose stores in case exercise intensity increases and oxygen availability is is reduced.
The runner's body will convert stored fat molecules into energy.

Which of the following statements about the action potentials in contractile myocardial cells (cardiac muscle) is INCORRECT? Compared to skeletal muscle cells, contractile myocardial cells have a lower (more negative) resting membrane potential. Action potentials are propagated between adjacent cardiomyocytes through gap junctions. The duration of an action potential in a contractile myocardial cell is greater than the duration of an action potential in a typical neuron. During the repolarization phase of a contractile myocardial action potential, the cell is highly permeable to sodium, potassium and calcium.
Answer: During the repolarization phase of a contractile myocardial action potential, the cell is highly permeable to sodium, potassium and calcium.
Explanation:
Apart from the fact that contractile cells conduct impulses, it also helps in contractions which are needed for pumping of blood. It should also be noted that the myocardial conducting cells serves as the heart's conduction system. They also have a lower resting membrane potential.
Of the options given, the answer is the last option i.e. during the repolarization phase of a contractile myocardial action potential, the cell is highly permeable to sodium, potassium and calcium. This is wrong.
Repolarization occurs due to a rise in the permeability of potassium and during repolarization, the calcium channels close.
