<span>Conifers are nonflowering plants that possess special c. roots to carry out reproduction.

<span>When conifers reproduce using these special structures, it is a form of a. asexual reproduction.</span>
Plants release nectar which attracts birds to come and eat. As the bird eats the plant pollen (plant sperm) will get on the bird, and travel with it to other plants were the pollen will falls off and impregnates another plants due to plants having both female, and male bodies thus causing cross-pollination. This happen thru natural selection because the plants has nectar and pollen due them wanting to be able to spread and have more offsprings.
Genetic variation is caused by mutations in the gametes and meiosis.
The large ears of the rabbits may help them hear when predators are coming. If they hear them coming, then they may be able to escape.
A polar bear with dark fur would be more obvious to its prey, who would more easily avoid him. The other white ones can blend in better and have a less chance of being detected by prey.
Organisms have genetic variation
The conditions change
The ones better at coping... survive
Survivors breed and pass on their variation
natural selection occurs
Some bacteria are more resistant
Antibiotic is added
Some bacteria survive
The survivors reproduce
Low levels of antibiotic remain

Answer:
The most accepted theory about the origin of Earth is that it formed by a process called planetary accretion
Explanation:
The most accepted theory about the origin of Earth is that it formed by a process called planetary accretion. In this process, the Earth is believed to have been formed from a cloud of gas and dust that remained following the Sun's formation. This cloud of gas and dust is referred to as the solar nebula.
Differentiation refers to the process by which the various layers of the earth were formed; core, mantle, and crust
