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.
The kingdoms in which these organisms should be classified are
organism A in Protist and organism B in Plant.There are a number of features that are shared by a large variety of organisms. The organisms with certain important features in common are put together into one group. The largest of these group is known as kingdoms.
The organism A belongs to kingdom protista because the kingdom bears the following features:
They are eukaryotes bearing membrane bound organelles.They are single-celled (unicellular) lacks a cell wall but contains a definite nucleus.The organism B belongs to kingdom plantae because the kingdom bears the following features:

what are the five layers of the atmosphere? Explain each layer.
Answer:
There is (from closest to the surface of the Earth) ...
Explanation:
Troposphere: the lowest region of the atmosphere, extending from the earth's surface to a height of about 3.7–6.2 miles (6–10 km), which is the lower boundary of the stratosphere.
Stratosphere: the layer of the earth's atmosphere above the troposphere, extending to about 32 miles (50 km) above the earth's surface (the lower boundary of the mesosphere).
Mesosphere: the region of the earth's atmosphere above the stratosphere and below the thermosphere, between about 30 and 50 miles (50 and 80 km) in altitude.
Thermosphere: the region of the atmosphere above the mesosphere and below the height at which the atmosphere ceases to have the properties of a continuous medium. The thermosphere is characterized throughout by an increase in temperature with height.
Exosphere: the outermost region of a planet's atmosphere.

True or False:
. Evolution happens because organisms need new features.
. Traits cannot be good or bad, their effect on the success of a creature depends on the environment and circumstances.
. A mutation in an individual is evolution.
. The process of evolution is random, but the selection of genes/traits is not.
. An organism that is more complex is more evolved.
. Only creatures that look similar share a common ancestor.
. “Survival of the fittest” means that the strongest, fastest, fiercest individuals are the ones
that get to reproduce.
. Except for differences between male and female, all individuals in a population are genetically the same.
. Nature is selecting for some traits and against other traits all the time.
. Evolution is a theory that is strongly supported by multiple lines of evidence from multiple fields of study.

Which of these could cause the amount of carbon dioxide in the atmosphere to decrease?
Answer:
An increase in the number of producers.
Explanation:
Producers/plants absorb carbon dioxide during photosynthesis and give off oxygen.Therefore to decrease the carbon dioxide in the air,we would have to plant more trees.
Have a nice day.
The percentage of carbon dioxide in the atmosphere should be 0.04% an increase in this amount can adversely affect the environment. Its amount can be decreased by increasing producers.
What is carbon cycle?Carbon cycle is the process of circulating carbon atoms from atmosphere to Earth and then again to atmosphere.
Carbon dioxide is increased in atmosphere by increasing respiration, increasing amount of decomposers, use of fossil fuels.
The way to decrease the concentration of carbon dioxide in atmosphere is by increasing number of producers.
Producers makes their food by absorbing carbon dioxide and release oxygen as a byproduct, hence decreasing the concentration of carbon dioxide.
Thus, the correct answer is D.

The cell grows in which phases?
A. G1, S, and G2
B. G1 and S only
C. G2 and S only
D. G1 and G2 only
Answer:
D. G1 and G2 only
Explanation:
Interphase is composed of G1 phase (cell growth), followed by S phase (DNA synthesis), followed by G2 phase (cell growth). At the end of interphase comes the mitotic phase, which is made up of mitosis and cytokinesis and leads to the formation of two daughter cells.
Answer:
D. G1 and G2 only
Explanation:
During interphase, the cell grows (G1), replicates its DNA (S) and prepares for mitosis (G2). A cell in interphase is not simply quiescent.

What are antibiotics and when can they not be used
Answer:
An antibiotic is a type of antimicrobial substance active against bacteria. It is the most important type of antibacterial agent for fighting bacterial infections, and antibiotic medications are widely used in the treatment and prevention of such infections. They may either kill or inhibit the growth of bacteria. Antibiotics DO NOT work on viruses, such as those that cause: Colds and runny noses, even if the mucus is thick, yellow, or green. Most sore throats (except strep throat) Flu.
Answer:
Antibiotics are medicines that help stop infections caused by bacteria. They do this by killing the bacteria or by keeping them from copying themselves or reproducing. Antibiotics do not work on viruses, such as those that cause colds, flu, bronchitis, or runny noses, even if the mucus is thick, yellow, or green. Antibiotics are only needed for treating certain infections caused by bacteria, but even some bacterial infections get better without antibiotics.

what represents the control group
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.
