Explanation:
Suppose a scientist is doing an experiment to determine the effect of an all-organic diet on the occurrence of
cancer in rats. Which of the following would be the best control group for this experiment?
A. Rats fed a standard rat diet (not organic)
B. Rats fed an all-organic diet
C. Pats fed an all-organic diet, but half the amount of normal
D. Rats that are not fed anything
Hmm... I'm not 100% sure but I'd say it was D.
Rats fed a standard rat diet (not organic) will be the best control group for this experiment. The correct option is A.
What is control group?A control group in a scientific experiment is a group that is isolated from the rest of the laboratory activity and where the regression analysis being evaluated cannot influence the outcomes.
This isolates the independent variable's effects on the experiment and can help rule out other explanations for the experimental results.
An experimental group is made up of participants who have their independent variable manipulated in some way. These are the people who receive special treatment.
The best control group for this experiment will be rats fed a standard rat diet (not organic).
Thus, the correct option is A.

9) List these biomes in order from the greatest to least diversity (temperate
deciduous forest, tropical rain forest, temperate rain forest).
Tropical rainforest, temperate deciduous forest, temperate rainforest
I'm not too sure if the temperate forest is more diverse than the rainforest, so sorry if I'm wrong. Tropical rainforests are the most diverse because of the humidity, which is water. The water helps the soil stay healthy, which makes more plants, which makes more animals and insects.
I hope this helps! Good luck!
The biomes in order from the greatest to least diversity will be tropical rainforest, temperate deciduous forest, and temperate rainforest.
Tropical rainforests refer to the rainforests that occur in areas that have no dry season.
The temperate deciduous forest refers to a biome that always changes. It has seasons such as winter, spring, summer, and fall.
Temperate rainforest refers to the broadleaf or coniferous forests that receive heavy rain. This condition supports ferns, shrubs, etc.
It should be noted that the biome with the greatest diversity is tropical rainforest while the least is the temperate rainforest.

Because most nerve cells do not typically undergo mitosis, they are generally not capable of which of the following?a.producing enzymesb.generating more nerve cellsc.performing cellular respirationd.transporting ions against a concentration gradien
Answer:
B. generating more nerve cells
Explanation:
Mitosis is the process whereby a cell divides into two genetically identical daughter cells. It is way through which living cells reproduce and multiply themselves.
Hence, a nerve cell that do not typically undergo mitosis will be incapable of replicating/multiplying itself, hence, unable to generate more nerve cells.

Plants participate in both short- and long-distance signaling. Explain how nerve cells show these two functions, as well. (3 points)
Nerve cells release chemical signals into synapses between them (short distance). They also transverse their lengths with an electrical signal that can result in signal travel along a series of cells (long distance).
Nerve cells release hormones into the synapses between them (short distance). These hormones can also transverse the bloodstream (long distance).
Nerve cells release neurotransmitters into gap junctions between them (short distance). They also use electrochemical gradients that can travel the length of each cell quickly, along a network of cells (long distance).
Nerve cells use plasmodesmata to communicate between them individually (short distance). They also use ion-gated channels to create an electrochemical signal that can be propagated over long distances in their network (long distance).
Answer:
Nerve cells release chemical signals into synapses between them (short distance). They also transverse their lengths with an electrical signal that can result in signal travel along a series of cells (long distance).
Explanation:
Nerve cells release neurotransmitters in the synaptic cleft which are capable of affecting nearby cells such as other nerve cells and muscle cells. Neurotransmitter molecules include, among others, serotonin, acetylcholine, dopamine, norepinephrine and histamine. Moreover, the synaptic cleft is the space that separates a neuron cell and its target cell. On the other hand, neurons transmit signals through electrical impulses. Electrical impulses travel long distances in the body carried by axons of the nerves. Thus, nerve impulses connect the brain and spinal cord and they carry signals to different parts of the body.
There are more hydrogen atoms in living organisms than any other atom, but oxygen is more abundant in terms of
mass.
Why is this statement true?
O Hydrogen is a gas, but oxygen is a solid.
O Hydrogen atoms have a lower mass than oxygen atoms.
• Hydrogen atoms make up more of water's mass than oxygen atoms.
Hydrogen is present as single atoms and oxygen is bonded in compounds,
Answer:
Hydrogen atoms have a lower mass than oxygen atoms.
Explanation:
The statement which is true is Hydrogen atoms have a lower mass than oxygen atoms. Thus, option C is correct.
What is hydrogen?
Hydrogen is the most abundanet element representing nearly three quarters of the mass of the universe. Hydrogen is found in the water that covers 70% of the surface of our planet as well as in all organic matter. Hydrogen is the simplest element in the universe. It is composed only of one proton (p) and only one electron (e-).
Hydrogen is the lightest element of all elements and gases; it is 14 times lighter than air. A "spill" of hydrogen gas immediately diffuses into the air and pollutes neither the ground nor the water table. Hydrogen is invisible, odorless and nontoxic. It does not cause acid rain, does not deplete the ozone layer and does not generate dangerous emissions.
Carbon is so abundant in living things even though oxygen is the most abundant element on Earth because carbon atoms can bond with one another to make chains and cyclic structures whereas oxygen atoms cannot form chains or cyclic structures.
Therefore, The statement which is true is Hydrogen atoms have a lower mass than oxygen atoms. Thus, option C is correct.

Which genus of single-celled organisms feeds by surrounding its food
with cytoplasm and engulfing it?
Answer:Amobea
Explanation:
The single-celled organism that feeds its food from the surrounding by engulfing is Amoeba. Amoeba is unicellular organism, generally found in freshwater pools, lakes, and in aquatic vegetation.
Amoeba is a unicellular organism belonging to the group of protozoa. It reproduces through binary fission. The amoeba has the ability to change its shape, which helps the organism to obtain food from the surrounding. Amoeba protrudes the cytoplasm by making a finger-like projections, known as pseudopodia. The pseudopodia engulfs the surrounding food particle by making a food vacuole. This process of engulfing food is known as phagocytosis.
Therefore, the amoeba uses phagocytosis to engulf food particle.
