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.
They feed by filtering feeding they feed on tiny organic material which is filtered through them
Answer:
Ribosome
Explanation:
Ribosomes are mainly made up of ribosomal RNA and ribosomal proteins. Each has two subunits (30S and 60S or prokaryotes) and 40S and 60S in eukaryotes. The smaller unit usually reads the mRNA -with the message from the nucleus -on how to ‘manufacture’ the proteins. The larger subunit actually does the translation by bringing in t_RNAs that carry specific amino acids and then forming peptide bonds between amino acids and ultimately forming polypeptide chains.
Covalent bonds are the strongest chemical bonds. They are chemical bonds in which electrons are shared between atoms.
