Answer:
Lysosome............Digest macromolecules.
Explanation:
Lysosomes is the membrane bound cell organelle that plays an important role in the cellular digestion. The proteins through the protein processing are transferred to the lysosomes as well.
Lysosomes are also known as suicidal bags as they have the ability to digest their own genetic material. The lysosomes contains acidic pH and different enzymes that are responsible for the degradation of macromolecules. Proteins, carbohydrates, lipids and nucleic acids are digested in the lysosomes.
Thus, the correct answer is option (a).
"The Sperm's Long Journey. A man may ejaculate 40 million to 150 million sperm, which start swimming upstream toward the fallopian tubes on their mission to fertilize an egg. Fast-swimming sperm can reach the egg in a half an hour, while others may take days. The sperm can live up to 48-72 hours."
NADPH is a reduced form of NADP+. The latter features an extra hydrogen ion in its chemical structure. When NADP+ transforms into NADPH, the other hydrogen ion is released as part of the reaction while the other hydrogen ion becomes a part of the NADPH structure.
Answer: d. all of the above
Renewable resources are those which can be replenished or reproduced at a faster rate. But heavily decrease in the volume of these resources sometimes cannot be compensated.
a. Loss of animal species: Hunting and poaching of animal species has limited the population of endangered species to derive valuables like horns, skins from these animals for human use.
b. Land degradation: Landmass occupied by natural forests and other natural biomes are cleared for human use like agriculture, mining, urban development. These lands are loosing their natural potential and are treated as waste lands.
c. Lower availability of fresh water: Water from water bodies like lakes, rivers, groundwater, ponds are polluted by industrial, agricultural wastes making water unfit for human use. Groundwater are pumped out to maximum amount but the same level cannot be maintained by natural sources of water such as rain, agricultural field irrigation, river or any other means therefore, limiting the level of water in grounds.
