Correct Answer: Progesterone
Correct Answer: Comminuted fracture
Correct Answer: Abu Baqre
Correct Answer: It attacks the body immune system
Correct Answer: Lymphatic system
Explanation:
Lipoproteins are particles that contain triacylglycerol (TAG), cholesterol, phospholipids and amphipathic proteins called apolipoproteins.
The four major types of lipoproteins are
1. chylomicrons,
2. very low-density lipoprotein (VLDL),
3. low-density lipoprotein (LDL), and
4. high-density lipoprotein (HDL).
Chylomicrons are formed in the endoplasmic reticulum in the absorptive cells (enterocytes) of the small intestine.
The function of these lipoproteins is to deliver energy-rich triacylglycerol (TAG) to cells in the body (pink pathway). TAG is stripped from chylomicrons and VLDL through the action of lipoprotein lipase, an enzyme that is found on the surface of endothelial cells. This enzyme digests the TAG to fatty acids and monoglycerides, which can then diffuse into the cell to be oxidized, or in the case of an adipose cell, to be re-synthesized into TAG and stored in the cell.
Correct Answer: Infra - red rays
Correct Answer: Thyroid
Explanation:
Cretinism is a disease caused by hypothyroidism (less thyroxine formation) . The symptoms of the disease are retardation of mental, physical and sexual developments. potbelly, protruding tongue, dry skin etc are also indicative of this disease.
Correct Answer: Chloroplast
Explanation:
The Chloroplast contains the wonder green pigment chlorophyll which is able to trap solar energy and use it for synthesis of food
Correct Answer: Ernst von Haeckel
Explanation:
The biogenetic law states that ontogeny (study of development) repeats phylogeny (origin from previous group of racial history), The young one of the frog namely the tadpole is like a fish cosidered to be ancestral to frog.
Correct Answer: adrenaline
Explanation:
The hormone adrenaline also called epinephrine is known as a stress harmone. In emotional upset (like fear, anger etc.) this harmone is poured into the blood and it accelerates heart beat. The hormone acetylcholine decelerates heartbeat rate.
