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: FALSE
Explanation:
Type 2 diabetes is the most common form of diabetes.
Correct Answer: Sensation
Explanation:
Sensation is the activation of the receptors by stimuli.
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: 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.
Correct Answer: The cell grows
Explanation:
The cell carries out the metabolic processes and it grows during interphase.
The cell cycle has three phases that must occur before mitosis, or cell division happens. These three phases are collectively known as interphase. They are G1, S, and G2.
Correct Answer: Yes
Explanation:
While plant cells have chloroplasts to photosynthesize, they also require ATP for cellular functions, and do use oxygen to break down some of the sugar they produce in order to generate that ATP. Cellular respiration takes place in the mitochondria. They need mitochondria for this reason.
Hence with this logic, we can say that Plants cells have mitochondria.
Correct Answer: DNA is called the blueprint of life because it contains the instructions needed for an organism to grow, develop, survive and reproduce DNA does this by controlling protein synthesis Proteins do most of the work in cells, and are the basic unit of structure and function in the cells of organisms
