In the jar shown, a sample of various sediment was mixed with water and then mixed with water and then allowed to settle for 24 hours. The jar served as a model for what process
Answer:
Process of sedimentation.
Explanation:
The jar shows us the model of sedimentation process because all the sediments settles down in the jar due to heavy weight. The sediment can't combine chemically with water and these sediments are heavier so due to gravity they comes down and settles down at bottom of the jar, this settlement of sediments in the jar is known as the process of sedimentation.

Form a hypothesis that explains your choice. You will be able to revise your hypothesis after performing experiments.
Hello. You have not informed the experiments to which the question refers, which makes it impossible for hypotheses to be formed. However, I will try to help you in the best possible way.
A hypothesis is an assumption, that is, it is a statement that the researcher believes to be true in relation to the research results, which can be proven or denied when the experiment is finished and the conclusions are established. Therefore, you must make assumptions about the results of the experiment, based on your primary visualization of them.
1. Define los siguientes pares de conceptos a partir de su semejanzas y diferencias A. ADN – ARN B. Acido Nucleico – Nucleótido C. Aminoácido – Proteína
Answer:
Las similitudes y diferencias entre ADN - ARN, ácido nucleico - nucleótido, aminoácido - proteína son las siguientes.
Explicación:
El ADN es similar al ARN debido a la presencia de cuatro bases nitrogenadas. La diferencia entre que tiene tres mismas bases nitrogenadas mientras que una es diferente. El ADN es bicatenario mientras que, por otro lado, el ARN es monocatenario. El ADN se considera más estable en comparación con el ARN sobre la base de su estructura.
Los nucleótidos son los componentes principales de los ácidos nucleicos, mientras que los ácidos nucleicos son los componentes básicos de la vida. Los nucleótidos están formados por nucleobase, azúcar de carbono y fosfato, mientras que, por otro lado, los ácidos nucleicos están formados por nucleótidos.
Los aminoácidos son los componentes básicos de las proteínas, lo que significa que las proteínas están hechas de aminoácidos. Las proteínas están conectadas entre sí, mientras que los aminoácidos libres no están conectados.

Having dimples (D) is dominant over not having dimples (d). If a person that is Dd has children with a person that is dd, what would be their children’s possible genotypes?
a
DD, Dd
b
Dd, dd
c
dd, DD
d
Dd, DD, dd
Answer:
A or D
Explanation:
Dd, dd would be their children's possible genotypes. Therefore, option (B) is correct.
The genotype of the first parent is Dd, which means they have one dominant allele (D) and one recessive allele (d). The genotype of the second parent is dd, which means they have two copies of the recessive allele (d).
When these two individuals have children, each parent will randomly pass on one of their two alleles to their offspring. Therefore, the possible genotypes of their children are:
Dd (with a 50% chance): the child inherits the dominant D allele from the Dd parent and the recessive d allele from the dd parent.
dd (with a 50% chance): the child inherits the recessive d allele from both parents.
Therefore, the correct option is (b) Dd, dd. The children cannot have a DD genotype because the second parent does not carry the dominant D allele.

A cell has undergone determination to become an epithelial lung cell. If it is transplanted to a leg muscle, what do you think will happen to this cell?
Answer:
Change occur in form and structure of the cell.
Explanation:
The structure and shape of the cell change because the function of leg is different from the lungs. In the lungs the epithelial lung cell is responsible for the detection and protection of the cells against pathogen while on the other hand, the leg has the function to move an individual from one place to another so due to difference in function, the cells of both regions have different shape and structure of the cell and the epithelial lung cell will be changed into a leg muscle cell.

A sea anemone has tentacles (similar to jellyfish) that deliver a chemical sting to animals that come in direct contact with them. Clownfish, however, are immune to the sea anemone's sting. They live among the tentacles of sea anemones and rely on the anemones for protection.
Sea anemones are filter feeders, and the movement of the clownfish increases the current of water flowing through the anemone. In addition, clownfish tend to drop scraps of food as they feed. What type of relationship exists between the clownfish and the sea anemone?
A. parasitism
B. predation
C. mutualism
D. commensalism
The type of relationship exists between the clownfish and the sea anemone is option c. mutualism.
What is mutualism?It refers to the ecological interaction that lies between two or more species at the time when each and every species has a net benefit.
Here, the anemone gives the clownfish along with the protection and shelter while on the other hand, clownfish gives the nutrients of anemone that could be in the form of wastage.

Make a claim about the types of wastes that the excretory system removes. Support your claim with evidence and explain your reasoning.
Answer:
Explanation:
Urea is the cellular waste product that the kidneys remove from the blood.Kidneys are the two bean shaped organs that has several functions to keep the body healthy. It not only removes urea from the blood, but also helps in the formation of urine and maintaining the fluid level of the body. The two kidneys are placed on the two sides of the spinal cord. The blood enters the kidney through the renal artery. The nephron within the kidneys mainly take out the waste products and the excess water from the blood and purifies it.If the kidneys of a person fail to work properly then it becomes important to perform dialysis for taking out the waste materials from the blood.
