Answer:
Protists are unicellular eukaryotes which show both plant and animal characters and these are considered as a bridge between plants and animals.
Explanation:
Protists are single-celled life forms and are eukaryotic organisms. Some of the protists like euglena shows both plant and animal characteristics. Protists are important in the following aspects -
- These are a good source of food for many animals. For example phytoplankton is the major source of food for whales. Zooplanktons also serve a good source of food for many aquatic organisms. These organisms often serve as the foundation of the food chain.
- By doing photosynthesis they also used to be beneficial in the balance of ecosystem.
- Some protists are also used as biofuel.
- They often show symbiotic relations with other organisms.
Answer:
Bad and good cholesterol.
Explanation:
The bad cholesterol generates low density liproprotein which is dangerous to the body system , hence the name "bad cholesterol". Most heart related diseases are linked to excess of the this cholesterol in the body. while the good cholesterol generates high density liproprotein that helps in discharging bad cholesterol from accumulating in the arteries .

Options for the question are not given. They are as follows:
a. arg or lys
b. ala
c. thr
d. leu or ser
e. Only termination codons
Answer:
d. leu or ser
Explanation:
Four codons code for proline amino acid. These are CCT, CCC, CCA, and CCG. Hydroxylamine causes C to change into T or G to change into A.
If first position is changed in each codon:
CCT = TCT (UCU)
CCC = TCC (UCC)
CCA = TCA (UCA)
CCG = TCG (UCG)
These codons produce Serine amino acid.
If second position is changed in each codon:
CCT = CTT (CUU)
CCC = CTC (CUC)
CCA = CTA (CUA)
CCG = CTG (CUG)
These codons produce Leucine amino acid.
Hence, out of the given options, option d. leu or ser is correct.
Water plants in the solution are placed under a bright lamp. Thus, option "B" is correct.
<h3>Explain your answer briefly?</h3>
As we know adding carbon dioxide in as solution result in the change of its acidity this is result in the indicator to change from blue to yellow. In the question, it is asked that what factors from the given option will cause yellow indictor to blue which means what factors cause the solution to be alkaline from acidic.
Placing the green water plants in the solution under a bright lamp will cause the is utilizing and remove present carbon dioxide in the solution and leads the to blue color from the yellow color of the solution.
Thus, this could be the answer.
The question is incomplete, however, the missing part is given as below:
A. Yeast cells and sugar are placed in the solution. B. Water plants in the solution are placed under a bright lamp. C. Algae are placed in the solution and left in a dark room. D. A person blows air into the solution through a straw.
