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.

How would Charles Darwin account for the diversity of living things
Answer:
Darwin's experience as a naturalist aboard the H.M.S. Beagle exposed him to the many living organisms distributed throughout South America. ... From these observations, Darwin determined that species did not arise independently; rather species are descendents of other species.

what are the effects of changes in one of earth four spheres on each of the other spheres?
Answer:
An event can cause changes to occur in one or more of the spheres, and/or an event can be the effect of changes in one or more of Earth's four spheres. This two-way cause and effect relationship between an event and a sphere is called an interaction. Interactions also occur among the spheres.

How does hydrogen peroxide get into cells?
Answer:
when a cell creates hydrogen peroxide, it stores it inside the cell's specialized organelles, called peroxisomes, which contain hydrogen peroxide-busting catalase.
Explanation:
Hydrogen peroxide gets into the cell with the help of an enzyme called peroxide dismutase, which significantly catalyzes the process of dismutation of superoxide radicals in order to synthesize H2O2.
What is Hydrogen peroxide?Hydrogen peroxide may be defined as a liquid chemical that typically contains hydrogen and oxygen and is generally utilized for bleaching and as an antiseptic.
Hydrogen peroxide is consistently produced in the cell and then stored in the organelle known as the peroxisome. The cells then eliminate the excess amount of hydrogen peroxide (H2O2) with the action of an enzyme called catalase. And gest dissociates into the water (H2O) and molecular oxygen (O2).
Therefore, the process of production and digestion of hydrogen peroxide in the cell is well described above.

As an ecosystem goes through succession, which of the following is likely to
happen:
A. Increase in biodiversity
B. Ecosystem will trigger Secondary Succession
C. Decrease in competition
D. Decrease in niches
Answer:
A
Explanation:
succession is replacement of one ecosystem by another so this cause increase in biodiversity
When an ecosystem goes through succession, the biodiversity of the ecosystem tends to increase. Thus, the correct option is A.
What is Succession?Succession may be defined as the gradual and continuous replacement of one community by another community over a long period of time.
Succession is always taking place by a better competitor. The first arrived species is known as the Pioneer species. Intermediate species are known as seral communities, while the highest species is known as the Climax species.
Overall, it increases the biodiversity of the region.
Therefore, the correct option is A.

what is the main purpose of WBC in blood platelets
Answer: You can consult:
They protect you against illness and disease. Think of white blood cells as your immunity cells. In a sense, they are always at war. They flow through your bloodstream to fight viruses, bacteria, and other foreign invaders that threaten your health.
Explanation:
I'm not sure but hope it helps.
Answer:
Explanation:
The cellular portion of blood contains red blood cells (RBCs), white blood cells (WBCs) and platelets. The RBCs carry oxygen from the lungs. The WBCs help to fight infection, and platelets are parts of cells that the body uses for clotting.White blood cells are part of the body's immune system. They help the body fight infection and other diseases. Types of white blood cells are granulocytes (neutrophils, eosinophils, and basophils), monocytes, and lymphocytes (T cells and B cells).
Imena is teaching her younger brother how to build a fire. As the fire sparks and starts to burn the kindling and wood in the fireplace, her
brother asks if the fire is alive because it is moving and growing. Imena tells her brother that the fire is not a living thing, and her brother asks
what makes something alive. What response does Imena give her brother?
250 words remaining
For something to be alive, it has to have essential characteristics. Some non-living elements share some of these characteristics with living things, but not all of them. That is what distinguishes one from the other.
The characteristics that all living things have are:
organization; sensitivity; growth; reproduction; homeostasis; and metabolism.
As regards organization, the minimum unit of life is the cell. For something to be a living thing, it has to be a cell or have multiple cells. They have organelles and organize to perform different actions.
The following characteristic is sensitivity, which means that the thing has to react to a stimulus by giving a response.
Living things grow. In other words, they increase in size thanks to the elements that they take from the exterior and process them taking what they need to grow. To do so, they use metabolism.
Metabolism is the combination of catabolism( the elements that the organism destroys) and anabolism( the elements that the organism builds). Metabolism is also essential for homeostasis. These are the different reactions that an organism has to have a balance.
The last essential characteristic is reproduction. Living things have to reproduce themselves, there are different methods, and they depend on the type of living thing that they are.
In conclusion, fire is not a living thing because it does not have cells that can have metabolism, sensitivity, homeostasis, and it can not reproduce itself.
A living thing has six main characteristics:
organization sensitivitygrowthreproduction homeostasis metabolismEven though the fire seems like a living thing because it is consuming wood, making noises, and moving, as many living things do, it is not alive because it does not have cells. As it does not have cells, it can not have homeostasis, react to stimuli, or grow as cells do. It might look like a living thing, but it is not since it does not have the six characteristics that every living thing has.

how the consumers in one level of the pyramid obtain energy from the organisms at the previous level of the pyramid
Answer:
by feeding on the organism on the previous level, the consumers at each level will receive energy. However, most of the energy is lost at each trophic level and very little gets transferred from one trophic level to another. Approximately, 10% of the energy is transferred from one trophic level to another.
Explanation:
hence, when a level takes energy from a previous level, the engery transfers but slowly gets less, so some levels get less energy depending on where the engery was located.

Tides occur in ocean,why?
Answer:
¿Qué Causa las Mareas? Podemos decir de una manera sencilla que las fuerzas de atracción que tanto el sol como la luna ejercen sobre la tierra, permiten una deformación y consecuente movimiento de las masas de agua de mares y océanos; esto hace que los niveles de agua suban y se formen las mareas.NOTA: Aquí anexo la respuesta en ingles.What Causes the Tides? We can say in a simple way that the attractive forces that both the sun and the moon exert on the earth, allow a deformation and consequent movement of the water masses of the seas and oceans; This causes the water levels to rise and tides to form.
Why are beakers and flasks not used to measure liquids
Answer:
Beakers and Erlenmeyer flasks should not be used to measure volume unless you need only a very crude estimate because their accuracy for volume measurements is so poor. They can hold a much larger volume than any of the other types of glassware, however, which makes them useful for mixing solutions.
Explanation:
Answer: Because they do not give accurate measurement
Explanation: beakers and flask are used to hold liquid higher in quantity or volume , so their measurement lines aren't precisely used for measuring nd it wont give u accurate answer EXCEPT u do a guess work or project

Answer:
White blood cells are an important part of the immune system. HIV infects and destroys certain white blood cells called CD4+ cells. If too many CD4+ cells are destroyed, the body can no longer defend itself against infection. The last stage of HIV infection is AIDS (acquired immunodeficiency syndrome).
