Answer:
Elongated shape
Explanation:
Centrifugation separates molecules on the basis of angular motion.
Due to spherical shape, the value of 'f' is lesser for a spherical protien than the rod shaped one.
Hence the sedimentation coefficient for an elongated protien is 2.6S while htat of a spherical protien is 4.31S.
Hence its elongated shape results in slow centrifugation.
Some of the important principles of centrifugation are as follows :
- The greater the mass, the more is the sedimentation rate i-e the one with greater mass will move down more rapidly as compared to the one with les mass.
- Shape of particles also effect it, the rounder the particle, the lower frictional coeeficient.
- Density of particles
- Density of fluid
Answer:
4 reasons here:
Explanation:
1) Adventure; boredom causes them to look for excitement, even if it's detrimental to their health.
2) Peer pressure;research shows that risk-taking among teens doubles when peers are around.
3) media;easy to guess, shows a lot of risky behaviour in glamorous or admirable ways.
4) Poor self-esteem; bullying can lead to poor self-esteem and higher chance of the victim becoming depressed and taking substance to cope with the depression, also leads to err, self-death
Both auxin and cytokinin are used to increase size of stem and fruits
In this case, c) mimicry is the answer. In Batesian mimicry in which harmless animals mimic toxic animals. In this case, I assume the milk snake is harmless and the coral snake is venomous. Since the milk snake has a trait similar to deadly coral snake, less animals would eat it thinking it is dangerous. Over time all the milk snake that look like the deadly coral snake would survive leading to evolution by natural selection. This would lead to more and more milk snake mimicking the resemblance of the deadly coral snake.
a) The deadly coral snake has a warning color adaptive radiation. If the question had described the environment and how the snaked adapted to the environment via warning coloration. This would've been correct.
b) cryptic coloration is more about camouflage with the environment. If the question had state how a certain feature help one of the animals blend into the background. This would've been correct.
d) I'm not sure whats different between this and a so i'll consider them both the same.
