Answer:
Explanation:
Due to the Sun's massive size, its large gravitational pull causes the planets and other objects in the solar system to orbit around it. In orbit around the Sun are the eight planets along with their moons, dwarf planets and many much smaller objects like asteroids and comets.
Answer:
A. True
Explanation:
Apoptosis is a normal cellular process in which the cell inherently programs the death of a mutated or damaged cell without affecting the healthy condition of the other surrounding cells by proliferating.
Apoptosis is a system of checks and balances that the cell uses to prevent damaged or mutated cells from proceeding to the next phase in the cell cycle. This curbs or prevent the damaged cell from passing on the problem to its daughter cells. Hence, according to this question, it is TRUE.
Answer: Option A.
participate in innate immunity
secrete granzymes and perforin
Explanation:
Cytotoxic T (TC) cells are like natural killer (NK) cells because they both because participate in innate immunity they are components of innate immune system i.e white blood cells that fight against disease or act as defence for infections.
NK cells can recognize and destroy cells that have regulated MHC class I molecules from their cell surface. They recognise the viral pathogens and activate the receptor that bind to the target cell and it releases cytotoxic granules that contain perforin and granzymes, which leads to lysis of the target cell and then it's clear off the infection by producing antibodies.
