Answer:
Hypotheis:
If high amounts of product in the samples, '+++' , correlates with optimal temperatures and pH for enzyme activity, then...
A- PepsinB- Amylase C- thermophilic enzymeExplanation:
Enzymes are specialized proteins that function as biological catalysts- they speed up chemical reactions. As proteins, these are susceptible to changes in temperature and pH- they function best at optimal values for both conditions, but can be denatured, rendering them inactive at relative extremes.
Each enzyme provided has its own optimal temperature and pH values.
Thermophilic enzymes are usually found in regions characterized by high temperatures. They show high thermostability, and do not become denatured at high temperatures- they thrive, and do not function well at lower temperatures.Amylase is a hydrolase digestive enzyme found in the mouth, that acts on polysaccharides like starch to break 1,4 glycosidic bonds between glucose molecules. It works best at a physiological (neutral) pH and temperatures (around 37°)Pepsin, another digestive enzyme, is a peptidase that breaks down proteins into peptide molecules. It is found in the stomach lining, where the pH is typically low i.e. acidic due to the hydrochloric acid in digestive juices.Thus from the table A- pepsin, B- Amylase and C- thermophilic enzyme can be hypothesized.
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
if one species in a community dies out or moves, the community will
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.
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.

client-centered therapy.
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.

O animal; 3X salt solution
O plant; pure water
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.Which statement is true for all prokaryotic and eukaryotic organisms?

B) Food enters your small intestines
C) Food enters your esophagus
D)Food enters your mouth
E) Food enters your stomach
Answer:
D; C; E; B; A
Explanation:
The mouth is the first part of the gut (gastrointestinal tract). When we eat, food passes down the gullet (oesophagus), into the stomach, and then into the small intestine. The small intestine has three sections - the duodenum, jejunum and ileum.
W Within a forest ecosystem, there is a large amount of diversity among members of a warbler species. Of the following stages of meiosis illustrated for a typical cell, which contributes most to diversity among the warblers? Pay special attention to the chromatids.
Answer:
Explanation:
How a Forest Ecosystem Matures . Forest ecosystems tend to always be moving toward maturity or into what foresters call a climax forest. This maturing, also called forest succession, of the ecosystem increases diversity up to the point of old age where the system slowly collapses. One forestry example of this is the growth of trees and the entire system moving toward an old growth forest.
A Large amount of warbler species, crossing over between homologous chromosomes, is closely involved in genetic variation. The stage that most contributes to diversity is stage C, where you can see chromosomes after crossing-over.
There are different mechanisms involved in producing genetic variation among descendants, are-
Crossing-over between homologous chromosomes (prophase 1), The Random lining of homologous chromosomes (metaphase 1), Random fertilization
The Crossing-over events occur between two homologous chromosomes within the equatorial plane and make the daughter cells genetically different from the first one.
The Chiasma is the position where two homologous chromatids interchange genetic information, giving an area for brand spanking new genetic material or information to be provided to descendants.
After crossover, homologous chromosomes get separated again. In the attached image there are four different stages of meiosis.
Stage C is the one that contributes foremost to diversity. We can see that crossover has already occurred between homologous chromosomes and that they have already interchanged segments.
In the image, you will see the difference between chromosomes that have gone through the crossing over mechanism, and chromosomes that have not. The difference in color represents segments interchange and variation.
Therefore, that answer shows the contribution to diversity among the warblers.

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.
