Which phrase best describes what a soil horizon is?
A the bottom layer of a soil profile
B each layer of a soil profile
C the place where two soil profiles meet
D the place where a soil profile meets bedrock
Answer:
I suppose the answer is C
Each layer of a soil profile best describes a soil horizon.
What is a soil horizon?A soil horizon is a layer of soil within a soil profile. A soil profile is a vertical section through the soil, showing the different layers, or horizons, of soil that make up the soil. Soil horizons are typically classified based on their physical, chemical, and biological properties, and they can vary in thickness and composition depending on factors such as climate, vegetation, and the underlying geology.
Some common soil horizons include the surface horizon, the subsoil, and the parent material.

4. How does the life of a sperm cell vary among the mosses, ferns, gymnosperms and angiosperms?
Answer:
They evolved on land to begin with from earlier now extinct groups groups so there was no need to adapt to life on land, other than to adapt to different terrestrial environmental pressures. Land can be everything from next to a river to a hot desert to rocks to Antarctica, and plants grow in all those places.
As well, there are thousands of species that are floating aquatics or submerged aquatics, including many ferns, and even some gymnosperms grow as marginals, and many species of angiosperms, mosses, ferns, and even some gmnosperms grow as epiphytes, or as parasites, or other ways.
1. What is the major source of energy for the brain
Explanation:
glucose
The mammalian brain depends on glucose as its main source of energy. In the adult brain, neurons have the highest energy demand [1], requiring continuous delivery of glucose from blood.
hope its helpful to you #
The major source of energy for the brain is glucose. Metabolism of glucose provides energy to the brain.
What is the brain?The brain is a body part that operates the various functions of the body. It is present in the head of the body. It is divided into two parts, the left brain, and the right brain.
Energy is something that is produced by the metabolism of food. Energy7 is required to carry out all the processes of the body. To walk, run, work, eat, everything requires energy.
The main source of the energy in animals and plants is glucose. The food we eat converts into energy by the process of respiration. The energy is transported into all parts of the body by blood circulation.
Thus, glucose is the major source of energy for the brain.

Why is it necessary for there to be variation in population in order for evolution by natural selection to occur?
Answer:
There needs to be variations in population in order for natural selection to occur because the entire point of evolution by natural selection is only the best variations will survive. So if there were no variations then there would be no natural selection because the animal's survival rate would be the same no matter how many times they reproduce because there are no different variations being introduced into the species. However, if there are variations then the animal's survival rate could be impacted because of the variations, for example, white mice would be easier to find for predators on a dark surface, while a darker mice would be harder to find for predators on a dark surface, thus, allowing the darker mice to prevail as they have a higher survival rate and the species will slowly evolve into the darker mice. But, if there were no evolution, in this case, then no matter what happens, the white mice would not be able to evolve into a darker mice because there are no such thing as variation. That is why it is necessary for there to be variation in order for evolution by natural selection to occur.

Koyi hai? ✌️
Answer:
When disaster strikes, an ecosystem can change very quickly. When an event causes a drastic decrease in a population, it can cause a type of genetic drift called a bottleneck effect.Hope this helps ~Answer:
The bottleneck effect is an extreme example of genetic drift that happens when the size of a population is severely reduced. Events like natural disasters (earthquakes, floods, fires) can decimate a population, killing most individuals and leaving behind a small, random assortment of survivors.
