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.

What posture is a dog displaying if she is leaning away from your, body lowered, ears back, tail down, showing whites of her eyes and the corners of her mouth pulled back.
Answer: Fearful and worried posture
Explanation:
Since dogs cannot talk, their body languages are used to interpret whatever emotion or feeling they may be experiencing.
When a dog is afraid, she tries to look small. She lowers her body and and leans away so that her center of gravity is over her hind legs to make a quick retreat easy. She also puts her tail down and ears flattened back to her skull. Her eyes also look rounder than normal and she shows the whites of her eyes (whale eyes).
All these tell that a dog is scared and worried or feeling tense.
Answer:
Defensive Threat Posture
Explanation:
Whale eye (whites of eyes showing)
Tail down or fully tucked
Piloerection
Ears back or flatten against head
Pupils dilated
Corners of mouth pulled back
Body lowered
Body leaning backward
A defensive threat posture indicates a dog is being self-protective. This is seen in a dog who is fearful and would prefer to run away from the situation, but may bite if provoked or cornered. Stress signals were offered in the beginning, however ignored and the dog is showing extreme fear.

Mendel also wondered if the inheritance of one trait affected the inheritance
of another. He explored this possibility by performing is -
A. dihybrid crosses
B. back crosses
C. test crosses
D. monohybrid crosses
And after can y’all help me on others 3 so I can sleep it’s already 12
Answer:
A. dihybrid crosses
Explanation:
A dihybrid cross can be defined as a mating experiment between two lines/varieties/organisms that differ in two phenotypic traits. By using pea plants, Mendel performed dihybrid crosses in order to analyze the mode of inheritance of both phenotypic traits at the same time. From these mating experiments, Mendel observed that the inheritance factors (nowadays called genes) sorted independently from one another in the next generation, which is called the principle/law of Independent Assortment.
Create a sentence explaining how amino acids
form proteins.
Answer:
Proteins are the final products of the sequencing process that begins with cellular DNA information.
Explanation:
Proteins form structural and motor components in the cell as workhorses of the cell, and they serve as the catalysts for virtually every biochemical reaction in living things. This incredible array of features stems from a remarkably simple code that defines a greatly varied collection of structures.
Lactase is an enzyme that many different animals have that helps digest the sugar lactose Why can this enzyme be the same in different species?
0 Lactase is necessary for survival of all organisms
0 All living things share a common code-DNA
0 Lactase is not regulated by external environments.
It is not possible for it to be the same in different species
Answer:
All living things share a common code-DNA
Explanation:
Enzymes are proteinous substances, which like every other proteins are encoded by a genes. In the expression of these genes, a set of codons (three nucleotide base) called GENETIC CODE is used. ONE of the characteristics of this genetic code is that it is NEARLY UNIVERSAL meaning that the same genetic code is used by virtually all known living organism.
According to this question, lactase enzyme, which helps digest lactose sugar in organisms, is the same in different organisms. This is due to the fact that all living things share a common code-DNA e.g AUG codes for methionine in all organisms, hence, when these DNA undergoes expression, it yields the same products in different organisms.

Are the four daughter cells produced by meiosis identical or unique?
Answer:
i think it's meiosis identical but im not sure please tell me if it's right or not
Answer:
[tex]\boxed {\boxed {\sf Unique \ daughter \ cells}}[/tex]
Explanation:
There are two main types of cell division: mitosis and meiosis. Mitosis makes identical cells for growth and repair.
On the other hand, meiosis is used for sexual reproduction.
In this reproduction, one diploid cell produces 4 haploid gametes/sex cells, meaning they have half of the genetic information. This is so during fertilization, when a sperm and egg combine, the zygote will have a full set of chromosomes.
One of the most important parts of meiosis is called crossing over. In this step, the chromosomes exchange information and create totally unique chromosomes.
This is one reason why siblings, aside from identical twins, can look similar, but not identical!

Answer:

Explanation:
"They mostly break down carbohydrates and fats. Once a protein source reaches your stomach, hydrochloric acid and enzymes called proteases break it down into smaller chains of amino acids. Amino acids are joined together by peptides, which are broken by proteases" - Protein Digestion: Enzymes, Absorption, and Ways to Improve

Answer:
D haploid (n) with a smaller number of chromosomes than the parent cells
Explanation:
meiosis results in gametes which have half the number of chromosomes and are therefore diploid because they have one set only. that is because later, the two cells with half the chromosomes (egg and sperm) join together to make a diploid cell
A domestic cat has 38 chromosomes in its skin cells, while a dog has 78 chromosomes. How does this fact help to explain why dogs and cats cannot interbreed?
Answer:
The sex cells could not easily combine to form the body cells of an offspring because of the different chromosome number.
Explanation:
The fact that dog and cats cannot be interbreed because there is difference in the no. of chromosome.
What is interbreeding?
The act of mixing different species or varieties of animals or plants and thus to produce hybrids is called interbreeding.
