3.In Boreal forest, the flora are: (a) Pine Larch (b) Palm Bamboo (c) Oak Fig (d) None of the above.

4. The only artery carrying deoxygenated blood:
(a) Coronary Artery () Pulmonary Artery (c) Aorta (d) Both (b) and (c)

5. The protein molecule present in blood plasma :
(2) Antibodies (b) Antigens (c) Platelets (d) Immunoglobulins.

6. When the heart relates the pressure of the blood is known as:
(a) Systolic pressue (b) Thermal pressure (c) Diastolic Pressure (d) Hypertension.

7 In human the chemical coordination is brought about by
(a) Enzymes (b) Hormones (c) Tissues

pls answer fast I will mark as brainlist

I don't know Number 3 so i can't answer.

4. (B) Pulmonary arteries the only artery in the choices that deliver deoxygenated blood.

5. (D) Immunoglobulins are proteins found in blood plasma.

6. (C) Diastolic pressure. I think you meant "relaxes" not "relates"

7. I think the answer is (A) Enzymes. Hormones can also be an answer i think.

can you give me more to work here with plzs and you

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.'
