- Question
Why is Meiosis called Reduction Division?
- Correct Answer
- Meiosis :: Meiosis is a type of cell division that reduces the chromosome number by half in daughter cells, creating four haploid cells, each genetically distinct from the parent cell that gave rise to them Why it is called as Reduction Division :: 1 As the Meiosis division process involves in reduction of chromosome number in the daughter cells to half the number in the parent cell, this process is called Reduction Division Meiosis creates gametes (egg and sperm cells) 2 The resulting gametes have 23 new chromosomes, one member of each of the 23 pairs, representing unique combinations of the original maternal and paternal copies

Correct Answer: Amount of oxygen dissolve in water
Correct Answer: Mitochondria
Correct Answer: Dichogamy
Correct Answer: Ecology
Correct Answer: exocrine glands
Explanation:
Glands are of two types. The exocrine glands have ducts to carry their secretions and these secretions contain enzymes. on the other hand, endocrine glands are ductless glands and they secrete mainly horomones.
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.
