Today, the Earth's axis is tilted 23.5 degrees from the plane of its orbit around the sun.
A eukaryotic cell has a nucleus as well as membrane bound organelles such as the golgi apparatus, endoplasmic reticulum ect.
I agree because an ecosystem and a host are basically the same thing.
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.
The probability of long hair is 50%. The probability of short hair is also 50%. So, the probability of one of their offspring having long hair is 50%
