Answer:
For the approach of how does pineapple consumption affect the number of digestive bacteria?, pineapple consumption is the independent variable (option B).
Explanation:
The formulation of a hypothesis is not complete without the existence of the independent and dependent variables, the main variables from the research point of view.
The independent variable is one whose change or modification is capable of impacting the dependent variable, which is one that can be quantified or measured.
According to the approach, if somebody want to know how the consumption of pineapple influences the number of digestive bacteria, the<u> independent variable is the consumption of pineapple</u>, which can be controlled and modified, while the <u>characteristic that is under the influence of this variable is the amount of bacteria</u>, so that the latter is the dependent variable.
The other options do not apply because:
- <em>The </em><u><em>experimental </em></u><em>(D) and </em><u><em>control</em></u><em> (A) </em><u><em>groups </em></u><em>refer to the population in which the study is conducted.
</em>
- <em>The </em><u><em>dependent variable</em></u><em> (C), in this case, is the amount of digestive bacteria.</em>
Answer:
Blood cells are responsible for constant maintenance and immune protection of every cell type of the body. This relentless and brutal work requires that blood cells, along with skin cells, have the greatest powers of self-renewal of any adult tissue.
The stem cells that form blood and immune cells are known as hematopoietic stem cells (HSCs). They are ultimately responsible for the constant renewal of blood—the production of billions of new blood cells each day. Physicians and basic researchers have known and capitalized on this fact for more than 50 years in treating many diseases. The first evidence and definition of blood-forming stem cells came from studies of people exposed to lethal doses of radiation in 1945.
Explanation:
asexual is from one singular parent . offspring comes from one singular cell . that should help you work through that !
The papaya, especially the green one, is used as a tenderizer in boiling red meat. This is because of the property of papaya's skin and leaves contain enzymes called papain. When this papain get contact to red meat the connecting tissue of the meat easily breaks down.
