Experiments with faulty design or inconsistent data:
-decreases the experiment's reliability and validity
- wastes time and resources
- destroys the scientist's credibility in their field
- may lead to issues of safety to the experimenter/s due to faulty design
- is discouraged especially in hard sciences where data obtained should be accurate and precise
Explanation:
There are many<span> reasons that experiments with faulty </span>styles<span> or with incorrect </span>knowledge are<span> problematic for scientists. One reason for them to be problematic </span>is that if<span> he or she were to poorly </span>live<span> what </span>they're learning<span>. </span>as an example<span>, </span>somebody<span> measured the mass of a book </span>properly<span> to be </span>two<span> pounds, and </span>somebody else<span> measured it </span>erroneously<span> to be </span>one<span> pound. </span>differently<span>, that faulty designed experiments and inconsistent </span>knowledge will be<span> problematic is lack of accuracy and </span><span>exactness.</span>
Answer: the mantle B
Explanation: Largest layer resulting in biggest mass.
The hypothesis that the scientist could test in his investigation is as follows: IF plants are given more than 2.0mg of magnesium, THEN their growth will be negatively affected.
<h3>What is an hypothesis?</h3>
Hypothesis is a tentative conjecture explaining an observation, phenomenon or scientific problem that can be tested by further observation, investigation and/or experimentation.
An hypothesis is commonly referred to as an educated guess because it tends to provide a temporary explanation for a phenomenon.
According to this question, a scientist investigated whether giving plants different quantities of magnesium affected their growth. He measured growth by counting the number of new leaves produced.
The hypothesis of the scientist regarding the above experiment could be as follows: IF plants are given more than 2.0mg of magnesium, THEN their growth will be negatively affected.

Answer:
Adaptive defenses include both humoral and cellular immunity.
Explanation:
The innate immune response is the non-specific immune response and serves to provide an immediate and general immune response. The adaptive immune responses are the specific immune responses. Adaptive immune responses include cell-mediated immunity and antibody-mediated immunity.
Cell-mediated immunity includes T cells (cytotoxic and helper T cells) while antibody-mediated immunity includes the production of antibodies from B cells. Binding of antigen to B cells is followed by their transformation into plasma cells and produce antibodies. Some of the activated B cells form memory B cells that are responsible for quicker and strong secondary immune responses.
