Answer:
A
Explanation:
Answer:
Predicting the genotype of offspring. Determine all possible combinations of alleles in the gametes for each parent. Half of the gametes get a dominant S and a dominant Y allele; the other half of the gametes get a recessive s and a recessive y allele. Both parents produce 25% each of SY, Sy, sY, and sy.

This is an example of how you complete the problem. I hope this helps! :)
A dihybrid cross is a breeding experiment that shows how two distinct traits are passed from parents to offspring. It's done using a Punnett square to determine the probability of offspring combinations.
A dihybrid cross is a breeding experiment that involves parents that differ in two distinct, genetically determined traits. In the study of genetics, The aim of a dihybrid cross is to determine the likelihood of offspring inheriting combinations of traits from their parents.
For instance, let's consider an example of crossing two pea plants. One possesses the traits for being tall with yellow seeds (TTYY) and the other being short with green seeds (ttyy). We can observe a dihybrid cross to predict the progeny's traits.
To do so, a Punnett square is used to visualize all the potential combinations of gametes resulting from meiosis. Later, these combinations can be analyzed to find out the probability of an offspring manifesting a certain combination of traits.
In short, dihybrid crosses provide a systematic method to study how traits are passed on to offspring generation. Its findings are fundamental to understanding the principles of genetics.

B) Bacteria can be treated with antibiotics, viruses cannot.
C) Vaccinations provide immunity from viruses, but not bacteria.
D) Vaccinations provide immunity from bacteria, but not viruses.
Answer:
That is correct on USATestPrep
Explanation:
Bacteria can be treated with antibiotics, viruses cannot.
Antibiotics won't treat viral infections because they can't kill viruses. Viruses are not living and depend on a host cell to provide the machinery for reproduction.
B) Bacteria can be treated with antibiotics, viruses cannot.
Antibiotics have no target when dealing with viruses. Antibiotics work on bacteria because it targets the growth machinery in bacteria. Viruses are found inside a human cell and reproduce by inserting their DNA into a human cell. There are antivirals and vaccines out there for viruses. Our body’s immune system fights against viruses with antibodies!
DNA replication is the process by which two DNA molecules are produced from one parent DNA molecule. DNA replication is semi conservative, this implies that, each strand in the double helix DNA molecule act as a template for the synthesis of a new, complimentary DNA strand. Because semi conservative method has a DNA template that is already accurately formed, the probability of having errors in the newly formed strand is drastically reduced.
Semi-conservative replication is a process of DNA replication in which each new DNA molecule formed contains one original strand (parental strand) and one newly synthesized complementary strand.
This type of replication occurs during the cell division cycle, ensuring that the genetic information is faithfully copied and passed on to the daughter cells without introducing significant mutations.
By combining accurate base pairing, proofreading, and repair mechanisms, semi-conservative replication ensures that the newly synthesized DNA strands are as identical as possible to the original parental strands. This fidelity in replication is vital for preserving the genetic information and preventing mutations that could lead to genetic disorders, cancer, or other harmful consequences in the offspring cells.

Soils, like clay, absorb water quickly.
B)
Sinkholes collect water above the water table.
C)
Land with no slope lets water runoff at a fast rate.
D)
Water in the soil zone is used by plants in life functions and leaf transpiration, but it also can evaporate directly to the atmosphere.
Answer:
d
Explanation:
Answer:D) Water in the soil zone is used by plants in life functions and leaf transpiration, but it also can evaporate directly to the atmosphere.
Explanation: Water in the subsurface soil zone is held together by capillary forces. It is also used by plants to carry out their life processes. The soil zone is crisscrossed by roots, openings left by decayed roots, and animal and worm burrows, which allow the precipitation to infiltrate into the soil zone. Water can also evaporate directly into the atmosphere.
