Answer:
They concluded that these antibodies were a) Globular proteins
Explanation:
Globular proteins are known to be water-soluble, spherical in shape and to be polypeptides as well. Compared to the other options provided, the selected one is the most correct.
1. information is transcribed in DNA to mRNA
2. mRNA leaves the nucleus
3. ribosome attaches to the mRNA
4. tRNA anticodon carries an amino acid that compliments the mRNA codon
5. the chain of amino acid forms a protein
Answer:

Explanation:
It is given that out of 40, total 5 specimen are selected.
Thus, the number of ways in which 5 specimens are selected from a given sample of 40 is given by

Number of specimen with certain trait is equal to 3.
Now, total 5 specimen are selected out of which one specimen is selected from the set of specimen that has certain trait (i.e out of 3) while the remaining four specimen will be selected from the rest
specimen.
Thus, the probability of choosing only 1 of the 5 specimens with the trait is equal to

I'm pretty sure these include light availability, oxygen levels, water movement, salinity, density and pH. These conditions often vary from habitat to habitat and will either support or limit the life processes of the marine organisms living there.
Hopefully that's right.
