Answer:
Chemogeny may be a theory of chemical evolution that depends on the chemical reactions and formation of drugs on the bases of chemical reactions. This theory says that “Life occurs as a results of evolution of inorganic matter”.
In the 1920's Scientists Oparin and Haldane, developed this hypothesis of the chemical origin of life from the primitive atmosphere of the world having matter like methane, ammonia and water. there have been very low concentrations of oxygen thanks to the presence of high temperatures like 5000-60000C. So, these conditions weren't suitable for the free existence of organic compounds, so reactions started happening .
Under conditions like high sunlight and warmth , inorganic matter gets converted to inorganic compounds. And this might end in the storage of organic compounds, which gets more and more concentrated with the passage of many years.
These compounds interact with one another and end in “life”.
So, chemogeny is that the process of chemical evolution of earth and formation of life from pre-existing matter with the assistance of chemical reactions.

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.

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.

An area that has been sampled to have a large population of organisms. Does this represent high biodiversity? Why or why not?
An area that has been sampled to have a large population of organisms is
regarded as having a high biodiversity.
Biodiversity is defined as the condition in which areas have a high amount
of plant and animal species present there. Any place with a large population
of organisms is said to have a high biodiversity while places with low
population of organisms have low biodiversity.
The stated facts therefore makes an area that has been sampled to have a
large population of organisms represents high biodiversity.

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.

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.
