Answer:
which control group are you talking about?
Answer:
A control group shall be the subject group without treatment or standard treatment. The Control group shall be the subject group. Nothing would be compared to the treatment group without the control group. Where statistics refer to "X times higher" the difference in measures between the treatment group and the control group is referred to. A basic feature in the experiment is the control group.
Explanation:
Exactly the same conditions as therapy groups will apply to the control group. This makes it possible to measure only the effects produced by the variable. For example, in a plant study, each plant would ideally be in the same space, under the same conditions of light and air.
Control groups are also used when medicines are tested on humans. While control groups were only considered to be good science, drug trials found an interesting phenomenon. Control groups are frequently found in drug studies in people who have a disease or ailment but are not tested for the medicine.
A fake medicine is given to the control group, and patients begin to see findings. This is called placebo by scientists and is still mainly unexplained. Some scientists suggested that people improve simply because they thought they would get better, but this theory is not tested.

Characteristics demonstrate that sea anemones are animals and not plants are;
The cells do not contain a membrane-bound nucleus; that is, they are prokaryotic.The organism consists of cells that perform chemosynthesis.What are sea anemones?. They are soft-bodied, sedentary colourful flower-like animals. They are attached to the sea bed with the help of a fleshy foot.
.Thus, the move of sea anemones is restricted. They are good predators and catch prey with their tentacles. Sea anemones possess features of animals thus, cell wall is absent in their cells

What is a nucleotide? What is an amino acid? What is a simple sugar (glucose)? What do these three share in common?
Answer: The three mentioned substances (nucleotide, amino acid and glucose) are the BASIC UNITS of its various biological macromolecules.
Explanation:
NUCLEOTIDE is defined as the BASIC UNIT or the building block of nucleic acid such as Deoxyribonucleic (DNA) and Ribonucleic (RNA). It contains a sugar molecule, a phosphate group and a nitrogen containing base. They have a variety of functions which include:
--> they are the building blocks of substance that control hereditary characteristics.
--> energy carriers,
--> components of enzyme cofactors, and
--> chemical messengers.
AMINO ACID: This is defined as the BASIC UNIT that makes up the biological macromolecule known as PROTEIN which helps in the growth and repair of worn out tissues of the body.
It is made up of basic amino group, an acidic carboxyl group, and a unique organic side chain.
GLUCOSE: This is also the BASIC UNIT of the biological macromolecule called carbohydrates. They are also called simple sugars which are the body's preferred source of energy in the form of carbohydrates.

Which of the following substitutions can help reduce air pollution?
using a bike instead of a car
using dumps instead of landfills
using coal instead of oil
using fireplaces instead of a wind farms
Answer: A. using a bike instead of a car
Explanation: TRUST ME!!! Answer is correct on Edge!!! :)
Using a bike instead of a car can help reduce air pollution by decreasing the number of cars on the road and reducing the emissions of greenhouse gases and pollutants from car exhaust. Therefore, option (A) is correct.
What is air pollution?Air pollution is the presence of harmful substances in the air that we breathe. These substances can come from natural sources such as wildfires and volcanic eruptions, but are mostly caused by human activities such as burning fossil fuels, industrial processes, and transportation.
Common air pollutants include particulate matter, ozone, nitrogen oxides, sulfur dioxide, and carbon monoxide, among others. Exposure to air pollution can lead to a range of health effects, including respiratory problems, heart disease, and even premature death. Air pollution also has significant impacts on the environment, including harming ecosystems, reducing crop yields, and contributing to climate change.

Organism A is eukaryotic, is unicellular, and lacks a cell wall. Organism B is eukaryotic, is multicellular, has a cell wall, and contains chloroplasts.
In which kingdoms should these organisms be classified?
organism A in Animal and organism B in Fungi
organism A in Animal and organism Bin Plant
organism A in Protist and organism Bin Fungi
organism A in Protist and organism Bin Plant
Answer:
A is protist and B is plant
Explanation:
Animals are multicellular, organism A cannot be an animal. Organism B is a plant and not a fungus because it has chloroplasts. Chloroplasts are organelles in plant cells that help make food through photosynthesis.

Which statement describes a difference between the nitrogen and carbon cycles?
The nitrogen cycle occurs entirely in the ocean.
The nitrogen cycle requires a process called nitrogen fixation that is carried out by certain bacteria.
The carbon cycle requires freezing temperatures.
The carbon cycle involves only plants.
Answer:
The nitrogen cycle requires a process called nitrogen fixation that is carried out by certain bacteria
The primary distinction between the carbon and nitrogen cycles is that the former involves recycling carbon, whilst the latter involves recycling nitrogen. There are numerous ways for both systems to recycle carbon and nitrogen. With gases, both cycles begin and end. Thus, option B is correct.
What between the nitrogen and carbon cycles?Both go through chemical changes that change the shape of the molecules they are contained in. All organisms that are living contain both nitrogen and carbon. Both entail releasing the element into the atmosphere in a molecular form. The cycles start and end as gases.
Therefore, The amount of nitrogen that can be absorbed into organic matter and then recycled rises as the flux of carbon does.Both involve releasing the element as a molecule form into the atmosphere. As gases, the cycles begin and finish.
