Answer:
Viruses exhibit two out of above mentioned which are
1. They contain genetic information
2. They reproduce
Explanation:
Viruses can be classified as either living or non living organisms
They can be classified as living organisms because of the following reasons
1. They can mutate
2. They can grow
3. They evolve to adapt to their hosts
4. They are capable of multiplication in their host cells
5. They are made up of proteins and glycoproteins like cells do
6. They have genetic information which helps them to produce more viruses in the form of either RNA or DNA.
They can also be classified as non living organisms because
1. They can not exist outside their host cell
2. They do not carry out metabolism, they make use of their host mechanisms
Answer:
have curved protofilaments at their plus ends
Explanation:
Microtubules are polymers of tubulin proteins that function as the cytoskeleton of eukaryotic cells. Microtubules are dynamic structures that can grow and shrink at a rapid rate. During this process, tubulin subunits can associate and dissociate at the plus end of the protofilament. Tubulin subunits bind to two GTP molecules, one of which is hydrolyzed to GDP after assembly. When microtubules are unstable, protofilaments curl outwards because GDP-bound tubulin has a weak affinity (thereby curving it) and disassemble. The dynamic stability of microtubules is regulated by a feedback loop: when microtubules shrink, free tubulin concentration increases and microtubules start to grow. As microtubules grow, free tubulin concentration decreases and the rate of GTP-tubulin addition also decreases.
Answer:
Adenosine triphosphate (ATP), is an energy-carrying molecule found in the cells of all living things. ATP captures chemical energy obtained from the breakdown of food molecules and releases it to fuel other cellular processes. When energy is needed by the cell, it is converted from storage molecules into ATP.
The answer is A ... mutation
Im pretty sure its plants
