Explanation:

The control group or the constants are the factors that remain the same in an experiment and also use as the factor to compare the other factors called variables that are subject to change in experiments.

The constant or the control group is the group that is not getting any treatment in or change in the experiments and uses as a standard to evaluates the other factors.

Glucose is broken down in the chemical processes of aerobic respiration.

Papessa [141]

$\bold{\huge{\purple{\underline{ Answer }}}}$

Aerobic respiration :- Aerobic respiration is process of respiration in which complete oxidation of glucose takes place in the presence of oxygen

That is, 

Aerobic respiration is takes place in four stages :-

Glycolysis
The link reaction
The Krebs cycle
Oxidative phosphorylation

In aerobic respiration, Glucose with 6 carbon atoms broken into 2 pyruvic acid each with 3 carbon atom and produces water + CO2 + energy.

<h3>Whereas, </h3>

Anaerobic respiration :- is the process of respiration in which incomplete oxidation of glucose takes place in the absence of oxygen

The end products of glucose in anaerobic respiration is

In human muscles,  Lactic acid + Energy
In yeast, Ethanol + CO2 + Energy

Hence, Option D is the correct answer.

Family plannings are initiated by the government as well as should be adopted by the couples in order to maintain a very healthy relationship as well a healthy population.

Family planning helps to reduce the poverty, hunger, epidemics, sexually transmitted diseases like AIDS etc and improves the maternal health, infant health, reduces maternal mortality rates, infant mortality rate, neonatal mortality rate etc. This uses the basic contraceptive methods as well as different other factors like when to take a baby and all.

A team of scientists conducted a study of grassland ecosystem and estimated the total energy at each trophic level. Their data i

maria [59]

Answer:

In grassland ecosystem, first trophic level is the producer. Producers are the organisms which makes their own food, here the producer are grasses. The second trohic level contain herbivores which feed on these grasses. These herbivores are eaten by secondary consumers which belongs to third trophic level and secondary consumers are then eaten by tertiary consumer.

The population of producers are very high so it is placed at the base while tertiary consumer are placed on the top due to low population.

Where does the waste material in the body come from and why does the body need to get rid of these waste materials?

Marizza181 [45]

"Waste" -- in the form of urine and feces -- how the body removes the parts of food we ingest that is not used for nutrition and also is a way to rid the body of toxins. The kidneys filter the blood, removing "waste" products such as excess vitamins or drugs (this is why your urine can have a bright color if you take high doses of vitamin c) and liquid waste is held in the bladder before being released. Food travels through the gut to be digested -- broken down into usable bits and waste. After breaking down in the stomach, the material travels through the small and large intestines. The small intestine is lined with villi -- tiny protrusions that add surface area so nutrients can be absorbed into the bloodstream. In the large intestine and colon, water is pulled from the mass so it becomes more solid. Eventually the solidified waste passed through the rectum and out the anus as feces. The build-up of waste in the body can itself be toxic -- if the kidneys do not function properly to clean the waste out, the buildup can be fatal. When the body goes into emergency mode to eliminate a toxic substance -- such as e. Coli in the case of food poisoning -- the intestines don't both absorbing water and the result is the liquid fecal matter being quickly passed through and ejected as diarrhea.
