Correct Answer: blood does not have a respiratory function
Explanation:
The blood of some invertebrate animals like the earthworm is red due to haemoglobin pigment, but the pigment is dissolved in the plasma. In vertebrates the same pigment is found in the red corpuscles and not in the plasma.
Correct Answer: mumps
Explanation:
Mumps: This is a swelling caused by inflammation of parotid glands placed in front of our ear region. The Inflammation is caused by a virus.
Correct Answer: holozoic
Explanation:
The feeding mechanism is of several types. If it is entirely plant-like (photosynthesis),it is called holophytic. It is entirely (holo) animal-like (zoic), that is devouring already existing food, it is called holozoic.
Correct Answer: Nucleotides
Explanation:
Genes: The DNA is the genetic material. The DNA is made of several nucleotides. A nucleotide means, one nitrogenous base one sugar molecule and a phosphate molecule. These Nucleotides occur in sequences and several nucleotides form one gene ( a functional gene is called a cistron)
Correct Answer: Blue
Explanation:
Lobsters, like snails and spiders, have blue blood due to the presence of hemocyanin, which contains copper. In contrast, vertebrates and many other animals have red blood from iron-rich hemoglobin.
Correct Answer: FALSE
Explanation:
Type 2 diabetes is the most common form of diabetes.
Correct Answer: Veins
Explanation:
Veins carries Blood back from the body parts to the Heart.
We know that The circulatory system of our body is a loop. The Heart is the pump, the arteries and their smaller branches (arterioles) carry oxygen rich blood all through your body and the veins and their smaller branches (venules) carry oxygen depleted blood and waste products back.
Correct Answer: replication of the DNA
Explanation:
Replication of the DNA does not occur during Mitosis.
Correct Answer: Haploid cells
Explanation:
Unlike Mitosis, Meiosis results in the formation of 4 Genetically different cells.
Meiosis results in the formation of 4 Haploid daughter cells from one Diploid parent cell.
Correct Answer: 1,000,000
Explanation:
There are about 1,000,000 nephrons in each human kidney.
Nephron, functional unit of the kidney, the structure that actually produces urine in the process of removing waste and excess substances from the blood.
