Fundamentally,
the cell would cease to function and possibly die. Proteins are used for
cellular repairing and chemical processes. Ribosomes are one of the most
important organelles in the cell, mostly part of the rough endoplasmic reticulum. It manufactures
enzymes such as proteins which will be utilized by many organelles in the cell.
Microtubules are one, responsible for the framework and acts as a skeleton of
the cell –cytoskeleton needs proteins, also cytoplasm and other organelles of
the cell. For a prokaryote or a eukaryote cell to survive, they need protein.
Answer:
True
Explanation:
Cell cycle checkpoints are an important layer of control of the cell cycle. The cell cycle is a process by which cells divide.
There are 4 stages of the cell cycle G1, G2, S and M.
When the cell goes through the cell cycle, each stage has different processes that must occur for the cell to properly divide. During G1, the cell must grow to sufficient size and the environment must be favorable for cell division. During S phase, all the DNA must be properly replicated. during G2 the cell must prepare for division. During M, the cell actually divides.
There are 3 checkpoints throughout the cell cycle. The G1 checkpoint ensures the cell has reached sufficient size. The G2 checkpoint ensures the DNA has been properly replicated. The M checkpoint makes sure the chromosomes are properly attached to the spindles to split the DNA between 2 new cells.
Without these checkpoints, the cell can divide uncontrollably which can lead to cancer.
Commercial:water used in business such as restaurants,hotels,offices,grocery stores,police stations,and malls.
Irrigation:water that is used for raising crops in dry areas.
Domestic:water used in rural areas where people dig wells.
Public:water that is delivered to homes and schools.
Btw this may not be 100% correct tried my best
<span>Two main characteristics that distinguish autotrophs from heterotrophs are:
A~ Autotrophs produce their own food by either chemosynthesis or photosynthesis. Heterotrophs do not produce their own food. Heterotrophs obtain their food by consuming autotrophs or heterotrophs.
B~ Autotrophs are at the primary level in a food chain and Heterotrophs are at the secondary level or tertiary level in a food chain.</span>
They are the raw material of genetic variation. Without mutation,evolution could not occur
