Answer:
Water is polar and Oil is non-polar.
Explanation:
A newborn child was brought to the hospital nursery before he was marked with his parents' names. The hospital workers must use what they know
about genetic outcomes to determine whom the child belongs to. They use his traits to help them. The baby has freckles (F dominant), and attached
earlobes (I recessive). They believe that the baby most likely belongs to a couple in which the man has attached earlobes but no freckles. It is known that
the woman is heterozygous for freckles and earlobe type.
Complete the Punnett square below to determine the probability that the child belongs to this couple. List the possible combinations of the father's
alleles across the top and the possible combinations of the mother's alleles down the left side. Then write your answer in the space below. Include a
brief statement explaining how you reached your answer.

Given the following phylogenetic tree, which evolutionary event occurred most recently?
A.) development of different forms of symmetry.
B.) development of tissues.
C.) each of these traits evolved at the same time.
D.) protostome and deuterostome development.
Answer:
Option-D
Explanation:
A phylogenetic tree is a diagrammatic representation which is constructed in to show the common ancestors at the base of the tree and the branches represent the new species.
The phylogenetic tree which is constructed based on the traits evolved during evolution is known as a cladogram. In the given question, the cladogram represents the evolution of various groups of the organism from a common ancestor based on the traits evolved.
The trait which was evolved earlier is present at the base like the development of tissues while the most common trait is present at the top which is the development of deuterostome and protostome.
Thus, Option-D is the correct answer.

State reason(s) why ash should or should not be used in making compost
Answer:
Fireplace ashes for compost can be used to help maintain the neutral condition of the compost. It can also add nutrients to the soil. Decomposing materials in the compost pile can become somewhat acidic and wood ash can help offset this, as it's more alkaline in nature. But Adding too much ash to the pile can be detrimental to the makeup of the compost because of its alkalinity. Ashes tend to raise the soil pH, so you shouldn't use it directly on plants, especially acid-loving ones like rhododendrons, azaleas, and blueberries. Also, in high amounts, wood ash can inhibit plant growth by restricting nutrients, like iron.

Which was not produced by volcanic outgassing?
O A. Oxygen
O B. Sulfur
O C. Water vapor
O D. Carbon dioxide
Answer: A. Oxygen
Explanation:
The component that was not produced by volcanic outgassing is oxygen, while the rest of all the released during the process of a volcanic eruption.
What do you mean by Volcanic outgassing?Volcanic outgassing may be defined as an eruption that releases a gas that was dissolved, trapped, frozen, or absorbed in some material.
Volcanic eruption transfers various gases from the interior of the Earth to the atmosphere leading to outgassing which includes water vapor, carbon dioxide, and sulfur.
Therefore, the component that was not produced by volcanic outgassing is oxygen, while the rest of all the released during the process of a volcanic eruption.

Natural selection is affected by which three factors? A. reproduction B. evolution C. variation D. overproduction E. mechanism F. competition
Natural selection is affected by evolution as three factor. The correct options are A, B and C.
Thus, Natural selection results in the transmission of advantageous genetic variants through reproduction.
As a result, a new generation of organisms emerges that has a higher chance of surviving and reproducing.
For instance, giraffes have an edge over other species due to their long necks, which have allowed them to graze on leaves that others cannot reach.
Because they had access to greater food, those with longer necks were able to breed and pass on the trait to the next generation. Less likely to survive and pass on their genes would be those with shorter necks and access to less food.
Thus, Natural selection is affected by evolution as three factor.The correct options are A, B and C.

explain how the products of photosynthesis are stored leaves!
Answer:
The products are stored in the form of starch because glucose is soluble
Explanation:
Answer:Although the cuticle provides important protection from excessive water loss, leaves cannot be impervious because they must also allow carbon dioxide in (to be used in photosynthesis), and oxygen out. These gases move into and out of the leaf through openings on the underside called stomata.

Predict how a loss of function mutation in the p53 gene is most likely to affect the cell cycle in response to DNA damage. Justify your predictions.
Answer:
The cell cycle of cell multiplication is regulated by three types of genes, the regulatory genes that control mutations, the generic promoters of cell replication, and genes that inhibit cell replication.
The balance between these three types of gene group are what result in a good multiplication of cells without mutations or neoplastic developments.
The p53 gene is one of the genes that is considered as the guardians of the genome, since it is in charge of corroborating and regulating mutated cells, in this way it inhibits their progression in the cell cycle by putting a stop to not replicate defective genes or genes with alterations.
Explanation:
The p53 gene is one of the most altered genes seen in malignant neoplasms, since by altering our guardian of the genome many mutations overlook and more carcinogenic potential will have neoplastic tissue.
In the three groups of genes that we write, all three have a fundamental roll in the cell cycle, but in order to trigger malignant neoplasms, it is necessary that there be a continuous series of gene mutations in these three groups, it is not enough with the mutation of a single gen.
