Factors that influence climate include latitude, prevailing winds, ocean currents, elevation, surface type, and landforms.
Provide an example of how two or more climate factors are related.
Please please answer this! I have it due today, and I really struggle with science!
Answer:
Two climate factors that are related are Elevation and Ocean Currents.
Explanation:
Ocean Currents depend on the altitude of Elevation. If the Elevation of land is below sea level it will have higher and more ocean currents, on the other hand, If the Elevation of the ground is higher than sea level it will see a decrease or almost nothing of Ocean Currents.

When one organism eats another, some energy is destroyed? (True or False)
Answer:
False
Explanation:
During strenuous exercise, the heart rate of an individual normally increases. Which factor is being regulated by this increase in heart rate?
A.water
B.oxygen
C.ammonia
D.temperature
Answer:
Increased heart rate, during strenuous exercise, helps to regulate the oxygen reaching the tissues.
Explanation:
Physical exercise implies an increased effort of the muscles, increasing the energetic demand and the substrate to produce more energy.
Both glucose and oxygen are needed by the muscle tissue during physical exercise, so the increased heart rate ensures the supply of oxygen to that tissue.
Therefore, an increase in heart rate contributes to the regulation of oxygen, whose requirements by the muscles increase with exercise.
Other options are not correct because:
A and C. Water and ammonia regulation is done at the renal level.
D. Regulation of temperature depends on the thermoregulatory center of the nervous system.
7. Explain why protein is an important part of a person's diet. (remember the important functions of proteins).

Which of the following organelles
are greatly reduced in animal
cells?
A. eukaryotes
B. lysosomes
C. nucleus
D. vacuoles
Answer:its D- vacuoles
Explanation: i did further research cause the other answer is bs
Vacuoles are organelles found both in plant and animal cells. However, these organelles are greatly reduced in animal cells (Option D).
Vacuoles are organelles that function to store substances (.e., food or nutrients, waste products, etc) both in plant and animal cells.
These organelles are filled with water and contain both inorganic (e.g., salts) and organic molecules (e.g., enzymes).
In animal cells, vacuoles are much smaller than in plant cells and they are often used to store materials and/or transport substances.
In conclusion, the vacuoles are greatly reduced in animal cells (Option D).

Asbestos is a chemical used to prevent fires but can cause lung disease.
What is Asbestos?Because of the fire resistance, chemical resistance, and insulating features that asbestos-containing materials (ACMs) provide at a low cost, they have been widely employed in building construction.Asbestosis is caused by breathing asbestos fibres or dust over an extended length of time. The lungs and pleura thicken and scar as a result of this (very thin tissue, or membrane, that line your lungs).

Trisha wants to find out whether a certain pesticide is carcinogenic to amphibians. Trisha is designing an experiment to test the problem. She is planning on exposing frogs of the same species to different amounts of the pesticide. Should Trisha include a control group in her experiment? A. No, Trisha will not need a control group because if any frogs develop cancer, it will be obvious that the pesticide is the cause. B. No, a control group is not necessary because Trisha will be testing different exposure rates of the pesticide. C. Yes, Trisha should have a group of frogs in her experiment that are not exposed to any pesticide at all. D. Yes, Trisha should use a different species of frogs as her control group.
Answer:
C. Yes, Trisha should have a group of frogs in her experiment that is not exposed to any pesticide at all
Explanation:
The election of a control group is essential in an experiment. Its principal purpose is to allow the discrimination of the results obtained by the treatment in the study (in this case, the effect of pesticide) from the results that might be a consequence of other factors. The control group must be selected from the same population of the treatment group. All the groups must be similar in every variable that might influence the results, except for the study treatment.
Control group: Frogs that are not exposed to any pesticideTreatment one: Frogs exposed to a certain concentration of pesticideTreatment two: Frogs exposed to an increased concentration of pesticides ...And so, the number of treatment groups will depend on the different concentrations of pesticides Trisha wants to study.
All groups must belong to the same population and of course, to the same species. They must also be exposed to the same variables, excepting for the pesticide variable.

Contrust a food chain to illustrate the flow of energy between the organism used in this simulation.
Answer:
Producers, or autotrophs, make their own organic molecules. Consumers, or heterotrophs, get organic molecules by eating other organisms.
A food chain is a linear sequence of organisms through which nutrients and energy pass as one organism eats another.
In a food chain, each organism occupies a different trophic level, defined by how many energy transfers separate it from the basic input of the chain.
Food webs consist of many interconnected food chains and are more realistic representation of consumption relationships in ecosystems.
Energy transfer between trophic levels is inefficient (with a typical efficiency around 10\%10%10, percent). This inefficiency limits the length of food chains.

3. What effect does an enzyme have on a chemical reaction
within a cell?
Answer:
Enzymes speed up the rate of a chemical reaction to help support life.But in Biochemical reactions , enzymes lower the activation energy of chemical reactions.Note ;Activation energy is the energy needed to start a chemical reactio
Explanation:
Digestive enzymes which are secreted in the acidic environment which has a low pH of the stomach help break down proteins into smaller molecules. The main digestive enzyme in the stomach is pepsin.
Enzymes accelerate the velocity of chemical reactions without consuming them or causing them to change permanently inside the cell.
What effect of enzyme on chemical reaction inside cells?
By lowering the activation energy and consequently raising the rate of reaction, enzymes (and other catalysts) work.
Since both directions must travel through the same transition state, the increased rate is the same in both the forward and reverse directions.
Cellular chemical reactions are accelerated (catalyzed) by enzymes. More precisely, they lower the barrier that must be crossed in order for the targeted reaction to occur.
By adhering to a substrate—an additional substance—they accomplish this.
Therefore, enzyme have effect on a chemical reaction within a cell.

What will happen to the rate of enzyme activity if substrate is continuously added to a fixed amount of enzyme while also being kept at an optimal temperature and pH
Answer: increased reaction rate
Explanation: more substrate = faster rr
Rate of reaction is directly proportional to the amount of enzyme and and substrate present. Therefore, at optimal temperature and pH rate of reaction will increase.
What affects the rate of reaction of enzymes ?
The rate of an enzyme-catalyzed reaction rises as the concentration of an enzyme increases. An enzyme-catalyzed process accelerates with rising temperature at low temperatures. The protein gets denatured at higher temperatures, which significantly slows down the process.
The pace of enzymatic processes depends on a number of variables, including
temperature, pH, enzyme concentration, substrate concentration, and the presence of any inhibitors or activators.Therefore, at an optimal temperature and pressure the rate of reaction will increase if substrate is continuously added to fixed amount of enzyme
