Amphetamine is a drug that suppresses appetite in most animals. To study the magnitude of this effect in rats a scientist randomly assigned thirty rats into three treatment groups to receive either a dose of amphetamine (2.5 or 5.0 mg/kg) or a control (saline, 0 mg/kg). Then food consumption was measured in grams per kilogram of body weight (g/kg) for the three-hour period after the injection.

Which of the following is not a testable hypothesis that this data could be used to support or disprove?
Answer:
b
Explanation:
this is because babies needs certain nutrient to grow faster which includes tallness
The statement that is not a testable hypothesis based on the given data is: being taller is always better than being shorter. Therefore option A is correct.
The given data provides information about the average height of females and males in different age groups. Let's analyze each statement to determine whether it is a testable hypothesis or not:
A. All men who are married are taller than their wives.
This statement cannot be tested using the given data because it only provides average heights for different age groups, but it doesn't provide any information about marital status or the specific heights of individual men and women.
Therefore, we cannot determine whether all married men are taller than their wives based on this data.
B. Height is affected by childhood nutrition.
This statement can be tested using the given data. By examining the average height changes across different age groups, we can infer whether childhood nutrition has an impact on height.
If there is a noticeable trend of increasing height from birth to older age groups, it could suggest a correlation between childhood nutrition and height.
C. Being taller is always better than being shorter.
This statement is subjective and cannot be tested using the given data. It is a matter of personal opinion and values, rather than something that can be objectively measured or proven.
D. All females are taller than males at age 12.
This statement can be tested using the given data. By looking at the average heights of females and males at age 12, we can determine whether females are, on average, taller than males at that specific age.

A study showed that the photosynthesis rate of a plant continually increased
over a certain period. Then the rate leveled off. During the study, light inten-
sity and temperature remained constant. The only variable was the concentra-
tion of carbon dioxide surrounding the plant. What was the cause of this
variation in photosynthesis rate?
Plsss helppp
Answer:
The photosynthesis uses carbon dioxide to produces glucose, so the bigger is the concentration, faster the plant will uses it (but that rate have a limit, so it is valid until the limit is achieved, like was explained in the question).
The rate of photosynthesis will increase as you go from low light intensity to high light intensity because there is more light available to power the processes of photosynthesis.
What is the photosynthesis rate of a plant?The higher the concentration, the quicker the plant will utilize the carbon dioxide to make glucose. However, that rate has a limit, therefore it is only effective until that limit is reached.
Because an increase in carbon dioxide results in an increase in photosynthesis, carbon dioxide is the limiting factor at lower concentrations.
Therefore, this indicates that the plant is absorbing more carbon dioxide for photosynthesis, and there is a greater intake of carbon dioxide.

Answer:
1)pancrease 2)rectum 3)salivary glands/liver
Explanation:
1)Lipase is an enzyme the body uses to break down fats in food so they can be absorbed in the intestines. Lipase is produced in the pancreas, mouth, and stomach.
2)Protease is present in gastric juice, stomach, intestine and digestive gland. Saliva and rectum contain traces of protease.
3)Physiology. Amylase is found in high concentration in the pancreas of virtually all animals. However, it is also found in the liver, salivary glands, and small intestinal mucosa of many species; the quantity of amylase in these organs varies considerably with different species

Answer:
1.They act as a catalyst
2.Enzymes are proteins
3.They are affected by Ph
4.They are affected by temperature
Explanation:
1.Enzymes act as a catalyst because they either speed up or slow down the rate of a reaction
2.They are proteins because they are made up of 20 amino acids
3.Enzymes are affected by temperature, if the temperature increases, the reaction rate increases. However if the temperature continues to increase, the shape of the active site changes.If the temperature is below preffered temperature range,the rate of the reaction becomes slower,but the shape is not denatured.
Determine whether the following statement is true or false and why. “Variation caused by the environment is not heritable, so it is not subject to natural selection.”

Answer:
True
Explanation:
Answer from gauth math
The statement "Variation caused by the environment is not heritable, so it is not subject to natural selection" is definitely true. Thus, the correct option for this question is A.
What is Variation?Variation may be defined as the indication of differences in the magnitude of response among individuals in an identical population given an identical dose of a compound.
Some variations are the results of differences provoked by surrounding or environmental factors. Such types of variations are called environmental variations. This type of variation is typically non-heritable in nature.
The variations that locate in the genomic sequence of an individual will tends to cause heritability and can pass from one generation to the next.
Natural selection deals with the process through which populations of living organisms adapt and change accordingly.
Therefore, the correct option for this question is A.
