How is a hybrid different from its originating crops?

Answers

Crossbred with other plant populations

A hybrid crop is different from the original crops as they contain genes from other crops that are beneficial for them.

A hybrid has the genetic makeup of both of its parent crops but may have completely distinct external characteristics. This is due to the fact that two recessive genes from both parent crops can be fused together to create an outward visible impact in the hybrid.

Hybrid plants are the result of the cross-pollination of two plant varieties and the propagation of the seed resulting from the mix. The plant that emerges from this seed combination is known as a hybrid plant.

What is population distribution?

Population distribution is how the population of something, plants, animals, or humans is distributed in specific areas. It specifies where people live or where they are not living.

There are three types of population distribution:

Uniform dispersion - In this distribution, the population is uniformly or evenly distributed in the areas. Even distribution comes under this distribution.Random dispersion - there are no predictable patterns in this dispersion. They are randomly present anywhere.Clumped dispersion - This distribution shows the bunch or group of population is areas then there is no population, and then there is a a bunch of population in another place.

Thus, the correct option is a. even.

how does matter move from the hydrosphere into the biosphere explain in your own words

Answers

Water moves from a river (hydrosphere) into the air (atmosphere) by a process called evaporation. Carbon dioxide moves from your body (biosphere) into the air (atmosphere) by a process called respiration. Minerals move from rock (geosphere) into the soil (pedosphere) by the process of weathering.

Water mover form hydrosphere i.e river to biosphere i.e atmosphere by a process of  evaporation.Thus, we can say that matter is move from hydrosphere to biosphere.

What is hydrosphere and biosphere?

Hydrosphere:-

The hydrosphere is the collective mass of water which is found on under, or above the surface of earth. Although earth hydrosphere is 4 billions old. A planet's hydrosphere can be liquid, vapor or ice.

Biosphere:-

The region or area of surface where living organisms survive their life are called as biosphere. The biosphere is a narrow zone on the surface of the earth where soil, water, and air combine to survive life.

Evaporation:-

The process in which water or liquid converts into vapor is called as evaporation.  In the case of water it starts vaporization at 100 degree C.

So, we can say that the conversion of matter from hydrosphere to biosphere is successfully achieved by evaporation.

Therefore, Water mover form hydrosphere i.e river to biosphere i.e atmosphere by a process of  evaporation.Thus, we can say that matter is move from hydrosphere to biosphere.

Why don't we have a complete fossil record of all life that's ever lived? Fossil formation requires a rare mix of physical and biological conditions. Fossils must be exposed at Earth's surface to have a chance of being found. Fossils can be destroyed when rocks erode, melt, or change composition.

Explanation:

For many reasons, the fossil record is not complete. Most organisms decomposed or were eaten by scavengers after death. Many species lacked hard parts, which are much more likely to fossilize. Some rocks and the fossils they contained have eroded and disappeared.

What caused the population of light-colored moths to decrease and the population of dark-colored moths to increase over time was because the dark-colored moths could camouflage themselves on the dark bark trees and the light-colored moths couldn’t protect themselves from predators because they had no where to hid.

Predict which color peppered moth would have a better chance of survival in your neighborhood? Explain why.

I believe that the dark-colored peppered moth would have a better chance of survival than the light-colored moths because there is mainly dark bark near my neighborhood instead of light-colored peppered moths.
