I think the correct answer among the choices listed above is the first option. In an ecosystem without primary consumers, the populations of producers would increase. This is because nothing will eat the the producers or the plants. The plants will only grow and increase.

Answer:

The correct answer is-

Hypothesis: Antibiotics cause weight gain in cows.

Independent Variable: Antibiotic pill

Dependent Variable: Weight of cow

Control Group: a group of cows gets a placebo pill

Experimental Group: a group of cows gets an antibiotic pill

Explanation:

The Independent variable is the variable that causes the response from the dependent variable or affects the dependent variable in this study the antibiotic pill affects the weight of cows so The independent variable is an antibiotic pill and the dependent variable is the weight of cows.

The control group is the group of subjects that did not get the treatment in a scientific study in the case of this study group of cows that receives the placebo pill is the control group and the experiment group is subjects that receive the treatment which is a group with the antibiotic pill.

JulsSmile [24]

Answer:

Pulmonary fibrosis is a disease that affects the lungs. The lung tissue becomes damaged and scarred which causes it to be thickened and stiff.

The condition pulmonary fibrosis is caused by the replacement of elastic fibers in the lung with inelastic collagen fibers. This decreases the lungs’ ability to stretch outwards.

Pulmonary fibrosis however mainly affects inspiration because the lungs cannot stretch to increase volume while during expiration stretching of the tissues doesn’t happen so it doesn’t affect the process.

IceJOKER [234]

Answer:

from the splitting of water molecule.

Explanation:

The splitting of water molecules by sunlight is called Photolysis. This is the first reaction in photosynthesis; which occurs by catalysis of enzymes of Photo system 11.

It involves the splitting of water molecules into;

hydrogen ion/protons.

Oxygen

and electron.

Oxygen is the by product liberated into the atmosphere, for animals to inhale for the process of cellular respiration.This is the source of oxygen fro cellular respiration in animals.

the hydrogen ions combined with electrons from photosystem 1 to reduce NADP .The latter is used to reduce C02 to form carbohydrate in light independent reaction
