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.

According to the video which type of biomolecule would want to have if you were swimming across the English Channel?
Arlecino [84]

Answer:

The answer is C

Explanation:

Therefore, in order to swim in the English channel, in which its waters are extremely cold, we need  carbohydrates like glucose that provide 4 kilocalories per gram. ...

Experts recommend that no more than 30% of the calories in our diet come from fat.

The diploid number for a lily whose pollen contains 12 chromosomes would be _________ and is produced when the pollen, containin
kirza4 [7]
The answers would be 24 and fertilises. 

Pollen is the male gamete of lily, which is a haploid cell, with only half the chromosomes of the normal diploid ones. Therefore, if the haploid gamete has 12 chromosomes, so the diploid would be 12+12 which makes 24. 

The egg is also a gamete of lily, but it's a female gamete. It is also a haploid cell, with only 12 chromosomes which is given in the question. So, when the sperm fuses and fertilises the egg, the zygote would have 24 chromosomes which is formed by 2 haploid gametes.

What is pollination?
katovenus [111]
Pollination is a very important part of the life cycle of plants. Insects, birds, bats and the wind take pollen between flowering plants, which means the plants can make seeds and reproduce (have babies!).
