Answer:
Cancer is unchecked cell growth. Mutations in genes can cause cancer by accelerating cell division rates or inhibiting normal controls on the system, such as cell cycle arrest or programmed cell death. As a mass of cancerous cells grows, it can develop into a tumor.
Water molecules stick to the cell walls of plant's thin veins which helps prevent the water from falling backwards due to gravity.
Answer:
3 is cell membrane, 5 is nucleoid and 6 is plasmid.
Explanation:
Structure 3 is cell membrane, structure 5 is nucleoid and structure 6 is plasmid. The structure 4 is cell wall which function is to protect the bacterial cell from outside environment. Bacteria develop resistance to antibiotics due to mutation which change its features. The same type and regular use of antibiotics leads to develop resistance in the bacteria. Plasmids can be used in the production of insulin for diabetics because plasmid has the ability to produce many copies of certain genes.
Answer:
A
Explanation:
Mitochondria are well known as the powerhouse of the cell, and as discussed in the section on Generation of ATP: Bioenergetics and Metabolism, in an active tissue such as heart, they are responsible for generating most of the ATP in the cell.
