O animal; pure water
O plant; 3X salt solution
Answer:
Plasmolysis occurs when a plant cell is inmersed in a 3X salt solution.
Explanation:
Plasmolysis is a phenomenon only observed in plant cells, and consists of cell dehydration accompanied by separation of the membrane and cell wall when the cell is exposed in a hypertonic environment.
When a plant cell is in a hypertonic solution —such as 3X salt solution— the permeability of its membrane allows water to escape, so the cell dehydrates and reduces its size. The cell wall is rigid and maintains its shape, but the cell membrane separates from it, which is known as plamolysis.
The other alternative answer combinations are not correct because:
Plamolysis does not occur in animal cells. Pure water does not produce plasmolysis.Suppose that you feel something brushing against your abdomen. The sensory information would be carried to the spinal cord over a ________ ramus. Suppose that you feel something brushing against your abdomen. The sensory information would be carried to the spinal cord over a ________ ramus. rami communicantes white ramus communicans posterior anterior gray ramus communicans
Answer:
The correct answer is - ventral ramus.
Explanation:
Ventral rami are the spinal nerves that bring the sensory information through the sensory fibers and motor fibers for the innervates the ventrolateral body surface, structures in the body wall, and the limbs, skin, such as abdomen and joints of limbs.
If someone feels the brushing sensation against his or her abdomen the sensory information must be carried by the ventral ramus.

When glucose, a 6-carbon sugar, is broken down during glycolysis, what product forms?
Answer:
pyruvate
Explanation:
In glycolysis, the 6-carbon sugar, which is glucose, is broken down into two molecules of a 3-carbon molecule called pyruvate.
During glycolysis, glucose is broken down into ; Pyruvate molecules and energy
Glycolysis is a cytoplasmic process during which glucose is broken down into two 3 carbon compounds ( pyruvate ) and energy is generated from t glucose in the process.
The breakdown of glucose during glycolysis is as represented below
Glucose + 2 NAD⁺ + 2ADP + 2Pi ----> 2 Pyruvate + 2 NADH + 2 H⁺ + 2ATP + 2 H₂O
Hence we can conclude that During glycolysis glucose is broken down into ; Pyruvate and energy.

In horses, black is dominant to chestnut and trotting is dominant to pacing. A heterozygous black and h o m o zygous pacer is crossed with chestnut and heterozygous trotting. What is the number of black pacers in a population of 260,000
Answer:
65,000
Explanation:
Black (B) is dominant to chestnut (b)
Trotting (T) is dominant to pacing (t)
A heterozygous black and h0m0zygous pacer (Bbtt) is crossed with a chestnut and heterozygous trotting (bbTt)
Bbtt x bbTt is the cross.
Potential alleles - Bt and bt bT and bt
Punnett square attached
Possible genotypes are: BbTt, bbTt , Bbtt, bbtt
Black pacers have the genotype BBtt or Bbtt
1:4 of the offspring have The Bbtt genotype.
If there are 260,000 in the population, then 260,000 / 4 would be black pacers.
260,000/4 = 65,000

Where are coral reefs most threatened by pollution, and what effects has pollution had so far?
Answer:
In the great barrier reef
Explanation:
It has effected plants and sea creature populations because of their homes being destroyed
Coral reefs are most threatened by pollution, as they are becoming extinct due to air pollution, water pollution, etc., and then human interference again lets them go extinct, and these reefs that are present in the site of the population are lost mostly.
What is the significance of the coral reefs' extinctions?Coral reefs are negatively affected by pollution and human activities, which include coral bleaching; and again, climate change that is caused by human activities such as the burning of fossil fuels, etc. induces the coral bleaching. Different chemicals that mix with water destroy the corals and the algae present in them.
Hence, coral reefs are most threatened by pollution, as they are becoming extinct due to air pollution, water pollution, etc., and then human interference again lets them go extinct, and these reefs that are present in the site of the population are lost mostly.

dialectical behavior therapy.
systematic desensitization.
aversive conditioning.
Explanation:
it is systematic desensitization.
Creating a list of anxiety-triggering situations and training in relaxation are important aspects of SYSTEMATIC DESENSITIZATION.
Systematic desensitization is a type of therapy based on the combination of relaxation methods with gradual exposure to the fear (phobia).The objective of the exposure to the fear is that the patient feels progressively less anxious about his/her phobia.In consequence, systematic desensitization increases the feeling of self-control and gradually reduces fear.In conclusion, creating a list of anxiety-triggering situations and training in relaxation are important aspects of SYSTEMATIC DESENSITIZATION.

Which human activity is correctly paired with the greenhouse gas that it increases?
rice cultivation and water vapor
landfilling and carbon dioxide
deforestation and methane
sewage treatment and nitrous oxide
Answer:
land filling and carbon dioxide
Explanation:
landfilling and carbon dioxide human activity is correctly paired with the greenhouse gas that it increases.
What is Landfilling?The emission of methane gas from landfills is the primary environmental issue. Methane gas is generated during the breakdown of organic material in landfills.
Methane is one of the most potent greenhouse gases and a major cause of climate change since it is 84 times more efficient than carbon dioxide at absorbing heat from the sun.
In addition to methane, landfills also release water vapour, carbon dioxide, and small amounts of oxygen, nitrogen, and other non-methane organic molecules. If not under control, these gases can also contribute to climate change and lead to pollution.
Therefore, landfilling and carbon dioxide human activity is correctly paired with the greenhouse gas that it increases.

Answer:
The community will slowly decline, or be just fine, or be better off.
Explanation:
Wolves being killed in Yellowstone showed that Yellowstone suffered, because there was nothing to kill the elk, so their population exploded and they ate everything.
If certain rats were gone in certain areas, then the community/environment would be fine, because rats eat birds and other small animals (they eat too many of them).
And if stray cats were gone then certain forests would be better off and see an increase in birds population, stray cats eat birds.
