Mosquitoes have a short lifespan and often die quickly due to humans, animals, or environmental causes. They also reproduce in a way that makes it easy to mate and to have as many offspring as possible. And due to their short lifespans, mosquitoes mate a lot more than squirrels.
Squirrels have longer lifespans and life expectancy and mate more like us, in a breeding season.
Answer:
1/2 of the offspring will have long legs and ears
Explanation:
Shown by the dihybrid cross, there are 4 possible combinations, of which, 2 will provide the offspring we’re looking for. This means we have a 2/4 ratio or 1/2 ratio.
Answer:
A protoplanetary disk is round rotating object which is made of dense gas. This surrounds the newly formed star, Herbig star and T tauri star.
It is also considered as a accreation because the remnants like gases and other materials fall from them on to the star.The extremely illuminating protoplanetary disk are known as the proplyds.
Whereas the nebula can be defined as the densely packed hydrogen and other gases that collapse under the force of gravity. The Nebula starts becoming smaller and smaller because the particles of gases collapse and get closer to each other.
Upon force of gravity their friction and heat increases which slowly collapse the star.
