Plzzz ! the protist seen here is called euglena. it is both animal-like and plant-like. it eats food but it also has chloroplasts like a plant cell, in order to make food. the euglena has one structure that it move. it is visible here. what is that cellular structure? a) cilia b) flagellum c) ribosomes d) golgi bodies

Option B, flagellum

Explanation:

Flagellum is a locomotory organ in Euglena that allows it to move through the water. A flagellum is located on the front or anterior side of body of euglena. It looks like a thread like structure which is capable to act like a motor.

Euglena can whip it flagella just like a helicopter propeller and thus it comes under the species category of "species with falgellatory locomotion"

Hence, option B is correct

hey, i believe your answer would be d. sugar ribose and the base uracil. i believe this is the answer, because rna consists of sugar ribose, adenine, guanine, cytosine, and uracil.

your first option is incorrect, because that's dna. where it consists of sugar deoxyribose, adenine, guanine, cytosine and thymine.

your second option is also incorrect, this is because sugar deoxyribose is in dna, and uracil is in rna. these two do not make sense together.

your third option being incorrect, because sugar ribose is in rna, but not the base of thymine. rna consists of uracil, not thymine.

lastly your fourth option being correct! this answer is correct, because both sugar ribose, and the base uracil are in rna! ~

answer is d. sugar ribose and the base uracil.

ans.

dna fingerprinting is defined as a process that determines the dna characteristics of an individual. these dna characteristics are unique among individuals as their fingerprints, so it is known as dna fingerprinting.

steps of dna fingerprinting includes extraction of dna from sample, amplification of dna, restriction digestion of amplified dna, and then analysis of dna by gel electrophoresis, respectively.

thus, the next step performed by the scientist is 'to cut the amplified dna (obtained by polymerase chain reaction) by restriction enzymes that cleave the dna into fragments and their analysis.'
