In an area where a river has cut deep into Earth, there are several layers of very different rocks exposed. The oldest layer is most likely the layer below the other layers. So the correct option is A.
What are different types of rocks?The combination of minerals whose properties result from the combination of all the aggregate minerals are called rocks. Rocks are categorized into different types depending on various properties.
Some of them are mineral composition, chemical composition, texture etc. The three categories of rocks are most commonly known.
These are Igneous rocks, Sedimentary rocks and Metamorphic rocks. The Igneous rocks are formed when the lava or magma from the volcanoes are cooled and solidified.
The continuous deposition of materials in water bodies results in the formation of Sedimentary rocks. This process is called sedimentation.
Metamorphic rocks are formed under the surface of earth when materials are deposited and subject to high temperatures and pressure. This process is called metamorphism.
Therefore the correct option is A.

Please helpppp meee!!!!its a final
Answer:
C. mountain lion-consumer; bark beetle-herbivore
Explanation:
Food webs contain a series of inter-connected food chains. In a food web, organisms in different trophic levels feed on one another to obtain energy. Based on the diagram attached to this question, the roles of different organism is as follows:
- MOUNTAIN LION: This is a consumer i.e organism that feeds on other animals. This is the case as seen in the diagram that mountain lions are feeding on rabbits and Hawks.
- BARK-BEETLE: This is an herbivore because it feeds directly on the plants as seen in the attached image.

Embryology, the study of the development of the anatomy of an organism to its adult form, provides evidence for evolution as embryo formation in widely-divergent groups of organisms tends to be conserved. ... Another form of evidence of evolution is the convergence of form in organisms that share similar environments.

A man and woman are deciding whether to have a child. The genotype of
the man includes a recessive allele for an inherited disease. The genotype of the woman
does not include this allele. Both parents have a normal phenotype. Could the child
inherit the disease? Explain your reasoning
Answer:
No, the child cannot inherit the disease.
Explanation:
The problem tells you that the man has a recessive allele for an inherited disease, but he has a normal phenotype. This means that the disease is recessive and in order for an individual to have the disease, they must have two recessive copies of the allele. The problem also tells you that the mother has a genotype that does not include this allele. With this information, you can do a punnet cross of BB (mother) x Bb (carrier father), and end up with the following possible genotypes: BB, Bb, BB, Bb. Therefore the child will not have the disease, but there is a 50% chance that the child will be a carrier for the disease.
No, the child cannot inherit the disease.
As the genotype of the man includes a recessive allele for an inherited disease.
What is dominant and recessive allele?Dominant refers to the relationship between two types of a gene. Individuals receive two types of each gene, known as alleles, from each parent.
If the alleles of a gene are different, one allele will be expressed, it is the dominant gene. The effect of the other allele, called recessive, is masked.
Thus, No, the child cannot inherit the disease.

What is the relationship between the masses of the objects and the gravitational force
between them?
I foron hotuen the two obiects in this
Answer:
They are directly proportional
Explanation:
The relationship between the masses of the objects and the gravitational force between them is such that both quantities are directly proportional to one another.
This is based on the Newton's law of universal gravitation.
The law states that "the gravitational force of attraction between two masses is directly proportional to their products and inversely proportional to the square of the distances between them".
So, the gravitational force is directly proportional to the masses of the two objects.
