In the ELISA procedure, first a protein sample is immobilized to a plastic well. Then, the antibody to the protein of interest is added, incubated, and the excess is washed out. Next, the detection antibody (which binds to the primary antibody) is added, incubated, and the excess is washed out. The last step is to add the detection dye (which binds to the detection antibody) to the wells and allow it to incubate. What do you predict the result would look like if you added the detection antibody first, then the antibody to the protein of interest

Answers

Answer:

In this ELISA procedure, a sample of protein is immobilized in the plastic well and then antibody for this protein added and incubated, and cleared out. In the given setting detection, the antibody is conjugated with the protein of interest and if the substrate molecule added to the reaction it will produce a colored product by reacting with the enzyme.

No reaction will take place in the well in case of not adding secondary antibody or detection antibody to the reaction and no colored product will be received.

Answer:

Chemical Weathering is erosion of rocks and surfaces by chemical reactions. Otherwise, it is weathering the does not occur by mechanical processes, such as expanding ice, cracking rocks, from extreme heat, and etcetera. It occurs when chemical reactors come in contact with objects such as rocks. For example, when slightly acidic water reacts with rock minerals and forms clay, and salts, that would be considered Chemical Weathering.

Answer:

B: a population’s age-sex structure

Explanation:

A population pyramid is a way to visualize two variables: age and sex.  

They are used by demographers, who study populations. A population pyramid is a graph that shows the distribution of ages across a population divided down the center between male and female members of the population. Expansive pyramids mean that the population does not increase much in total number and has many young people.

O The plant would have enlarged root cells.
The plant would have damaged root cells.
O The plant would not be able to grow to normal height.
O The plant would not be able to absorb water from the soil.

Answers

Answer:

The plant would not be able to grow to normal height.

Explanation:

If a plant does not develop a root cap, the plant does not allow the root to grow downwards.

Hope this helps :)

If a plant is unable to produce root caps, the plant will be unable to absorb water from the soil; this is the final option, as root caps are a specialized protective layer at the tip of plant roots that help protect the plants.

What is the significance of the root cap in the plants?

The root cap contains cells that are capable of secreting slime, which helps the root to move easily through the soil, helps to maintain the proper orientation of the root tip so it can efficiently absorb water and nutrients from the soil, and acts as a barrier that protects the delicate root tip cells as the root grows through the soil.

Hence, if a plant is unable to produce root caps, the plant will be unable to absorb water from the soil; this is the final option, as root caps are a specialized protective layer at the tip of plant roots that help protect the plants.

noah created a model of a glacier to help explain how glaciers change the surface of Earth. He froze two large blocks of ice. One block was pure water. The pther was water mixed with sand and rocks. He took both blocks and rubbed them across a sheet of tinfoil. The block of pure water slid smoothly over the tinfoil. The block with sand and rocks ripped the tinfoil in many places. How does Noah's model explain how glaciers change Earths surface?

Answers

Answer: The model is depicting the glacier erosion.

Explanation:

The glaciers are responsible for causing erosion of the earth. They transport the materials away from the locations were they are earlier situated. They carve the materials present beneath the land. They erode the materials like soil, pebbles, boulders, against the pressure of the unstable mass of the ice moving down the slope. The broken ice mass carriers away the broken rocks, materials and soil debris far away from the places where they have been originally situated. This causes the glacial erosion. Also the broken and displaced rocks displace the soil and other materials come in contact with during erosion.

According to the given situation, the ice formed with water only had no impact on the tinfoil on the other hand the ice containing the sand and rocks removed the tinfoil from places. This is because of the friction created by the sand and rocks on the tinfoil. The glacier material like ice, soil, rocks due to friction erode the material come in contact with it with an appreciable pressure underneath.

Answers

Answer:

it is c: glycolysis

Explanation:

its correct on edmentum

Glycolysis is a process of biochemical importance which receives a supply of NAD+ions from the fermentation process during anaerobic respiration. Therefore, option (C) is correct.

Glycolysis  occurs in both aerobic and anaerobic respiration and is a  metabolic process. During anaerobic respiration, glycolysis is the only process that produces ATP.

In the absence of oxygen, the electron transport chain cannot function, and therefore, the Krebs cycle and electron transport system are not active. Therefore, glycolysis is the correct answer.

Before 1896, many scientists concluded that light could not pass through black paper. In 1896, Henri Becquerel observed that uranium salts could cause a plate covered by black paper to react as if light had reached it. How did this observation affect conclusions about light passing through black paper?

A- Scientists ignored Becquerel’s evidence because uranium is dangerous to use, so his study was not valid.

B- Scientists repeated Becquerel’s experiment until it no longer worked and reported that his conclusions were not valid.

C- Scientists had to revise their earlier conclusion because evidence from Becquerel did not support the original conclusion.

D- Scientists stood behind the earlier conclusion that black paper blocks light because it was already an accepted conclusion.

Answers

Answer:

D

Explanation:

So, I mean it’s kinda hard to explain given that it just makes sense and I took the test and I was right soooooooo

Yeah

Scientists stood behind the earlier conclusion that black paper blocks light because it was already an accepted conclusion. Therefore, option (D) is correct.

What happens to light on the black paper?

A sheet of black construction paper would obstruct light when you tried to shine a flashlight through it. The other side would not be able to see the light, and it would not be reflected. A black item absorbs all light waves and transforms them into heat, which causes the object to warm up.

Uranium, according to Henri Becquerel's theory, would absorb light and reemit it as x-rays. The uranium was placed on photo plates by him. When the plates were developed, he saw that the uranium had in fact been generating radiation resembling x-rays.

A corn plant has been genetically engineered. It produces pollen that can make its own toxins. These talks and protect the corn plant against pests.Newer strains of pesticide-resistant pests may develop. Option D is correct answer.

What are pesticides ?

These are the chemicals that kill the pests and these are given to the crops so that they can be saved from pests.

Bird and butterfly populations around the area may increase. It is possible if the flowers and the pollen grains number and the production is increased. The carbon dioxide level would increase in the area. In this situation the plants number gets increased.

The concentration of pesticides in a nearby lake would increase. In this situation the pest use is increased on the plants and in this situation the use of chemicals in the surrounding water resources will be increased.
