Answer:

1) d. observe phenomenon; generate hypothesis, conduct experiment, accept, reject, or modify hypothesis.

C. A study that compares a aroup of people with diabetes to a similar aroup of people without diabetes is an example of a case-control study.

Explanation:

Scientific method is a step by step procedure ranging from observing a problem to actual experimentation that aims at investigating a problem. The steps involved in the scientific method are as follows:

a)observe phenomenon; This precedes every experiment in the scientific method.

b) generate hypothesis: This is a testable explanation given as a possible solution to the observed problem.

c) conduct experiment: The hypothesis is tested via experimentation.

d) accept, reject, or modify hypothesis: Based on the result of the experiment, the hypothesis can be rejected, accepted or even modified.

Question 2:

Case control study is a type of study design that uses or compares a group of affected individuals (by a disease) called CASES and unaffected individuals called CONTROL. In this case, A study that compares a group of people with diabetes (cases) to a similar aroup of people without diabetes (control) is an example of a case-control study.

the frogs tongue is anchored in the very front opposite to the orientation and anchoring of humans why is that?
Mice21 [21]
Frog's tongues are attached to the front of their mouths rather than at the back like humans. When a frog catches an insect it throws its sticky tongue out of it's mouth and wraps it around its prey. The frog's tongue then snaps back and throws the food down its throat.

In general, why might cell-wall inhibiting antimicrobial drugs be less effective on gram-negative bacteria compared to gram-posi
asambeis [7]

Cell-wall inhibiting antimicrobial drugs be less effective on gram-negative bacteria compared to gram-positive bacteria because the outer membrane of the gram-negative bacteria inhibits penetration of the drug and the peptidoglycan found in gram-positive bacteria is structurally different from that in gram-negative bacteria.  

Answer: Option B & C

<u>Explanation:</u>

Antimicrobial drugs are induced into a body to act on that particular selective bacterium which causes disease. When antimicrobial drugs are injected they act efficiently on the gram positive bacteria inhibiting the proliferation of the cells by acting on the cell wall so that cell multiplication doesn’t happen.

On the other hand it is hard to act on the gram-negative bacteria as it has a cell membrane that inhibits drug penetration into it. Both cell walls contain peptidoglycan but in the gram-positive is more assembled and layered while in the gram-negative it is just a thin layer. As gram-positive is thick layered it provides place for another molecule to attach to it but the thin layer in gram-negative inhibits it.
