Answer: On Earth, human activities are changing the natural greenhouse. Over the last century the burning of fossil fuels like coal and oil has increased the concentration of atmospheric carbon dioxide (CO2). This happens because the coal or oil burning process combines carbon with oxygen in the air to make CO2.

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
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:
Wiskwkkswkwkwkwkwkwkwksks
Explanation:keksjsisiwwkkwkaakkaakksks
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.

What does a population pyramid represents?
A
a population’s trophic levels
B
a population’s age-sex structure
C
a population’s growth rate
D
a population’s dispersal pattern
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.

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.

Which statement describes the role of decomposers in moving nutrients through a food web?
Answer:
Every part of an ecosystem is vital to its survival – from the green plants to furry animals and microscopic bacteria. The group of organisms called decomposers forms the final link in the food chain. They break down dead animals and plants and return vital nutrients to the soil.
Explanation:
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.
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.

Next
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.
