Answer:
100 %
Explanation:
Dominance is a genetic phenomenon where a gene variant or allele masks the effects of another allele (of the same gene) in heterozygous individuals. This last gene variant is referred to as the recessive allele. In this case, the silkworm mother can produce only one type of gamete carrying the dominant gene (B) form, while the silkworm father can produce only one type of gamete carrying the recessive gene (b) form. In consequence, from this cross, all offspring (100 %) will be heterozygous (Bb) and therefore they will express the dominant trait (i.e., yellow cocoon).

List and explain the 3 paths natural selection can take.
Answer:
1. Stabilizing Selection
2. Directional Selection
3. Disruptive Selection
Explanation:
Stabilizing Selection
This type of natural selection occurs when there are selective pressures working against two extremes of a trait and therefore the intermediate or “middle” trait is selected for. If we look at a distribution of traits in the population, it is noticeable that a standard distribution is followed:
Example: For a plant, the plants that are very tall are exposed to more wind and are at risk of being blown over. The plants that are very short fail to get enough sunlight to prosper. Therefore, the plants that are a middle height between the two get both enough sunlight and protection from the wind.
Directional Selection
This type of natural selection occurs when selective pressures are working in favour of one extreme of a trait. Therefore when looking at a distribution of traits in a population, a graph tends to lean more to one side:
Example: Giraffes with the longest necks are able to reach more leaves to each. Selective pressures will work in the advantage of the longer neck giraffes and therefore the distribution of the trait within the population will shift towards the longer neck trait.
Disruptive Selection
This type of natural selection occurs when selective pressures are working in favour of the two extremes and against the intermediate trait. This type of selection is not as common. When looking at a trait distribution, there are two higher peaks on both ends with a minimum in the middle as such:
Example: An area that has black, white and grey bunnies contains both black and white rocks. Both the traits for white and black will be favored by natural selection since they both prove useful for camouflage. The intermediate trait of grey does not prove as useful and therefore selective pressures act against the trait.

Methylmercury biomagnifies in an ecosystem, meaning its concentration __________ as it moves through each higher trophic level.
A. equalizes
B.does not change
C. decreases
D. increases
Answer:
D - Methyl Mercury Increases
Explanation:
The word Biomagnification has a simple explanation:
To magnify is to make bigger, meaning that the substance in question is becoming more abundant.
The "bio" part of this word is referring to the fact that it is a biological substance you are dealing with.
Question: "Methylmercury biomagnifies in an ecosystem, meaning its concentration __________ as it moves through each higher trophic level."
Answer: "The concentration of the methylmercury increases as it moves through each higher trophic level. Hence, the methylmercury biomagnifies in the ecosystem. So, based on the options given prior to the question above, Option D) increases would be your best bet."
Which sediment would have the slowest rate of deposition?
a round sediment
O a very large sediment
an irregularly shaped sediment
O a high-density sediment
Answer:
C. An irregularly shaped sediment
Explanation:
Deposition is the settling of sediments within respective basins of deposition.
Irregularly shaped sediments are the slowest to settle within a basin this is due to the frictional resistance of their surface.
As these particles hits the water, the liquid drag on their edges is very great and prevents swift settling.
A. A high density sediment and a large sediment will have a fast settling time.
B. Rounded sediments will impose no friction on the water and they fall through the liquid very fast.
Answer:
the answer is C. an irregulary shaped sediment

2.
Use Models Use the genetic code to translate the sequence into each of the three possible sets of amino acids.
3.
Draw Conclusions Which of the three sets of amino acids is the most likely to be included in the polypeptide? Explain your reasoning.
Answer:
TAA ATT GAC AAG ACA GAT CTC
1. The more bases there are per codon the more information you can code for. There are only 22 different amino acids, in consequence we need minimum 3 bases per codon.
2. codon
three nucleotides—called a triplet or codon—codes for one particular amino acid in the protein. The nucleotide sequence in the DNA is first transcribed into a molecule of messenger RNA (ribonucleic acid).
3. Known as alpha helices and beta sheets, these stable folding patterns make up the secondary structure of a protein. Most proteins contain multiple helices and sheets, in addition to other less common patterns (Figure 2). The ensemble of formations and folds in a single linear chain of amino acids — sometimes called a polypeptide — constitutes the tertiary structure of a protein. Finally, the quaternary structure of a protein refers to those macromolecules with multiple polypeptide chains or subunits.
OKAY I THINK EVERYTHING IS RIGHT BUT SORRY IF WRONG ;)
3. It is not possible to determine which of the three sets of amino acids is the most likely to be included in the polypeptide based solely on the information provided.
What is a nucleotide sequence?A nucleotide sequence is the order of nucleotides (the building blocks of nucleic acids) in a DNA or RNA molecule.
Nucleotides are composed of a sugar, a phosphate group, and a nitrogenous base, which can be adenine (A), cytosine (C), guanine (G), thymine (T) (in DNA) or uracil (U) (in RNA). The specific order of these nucleotides in a DNA or RNA molecule determines the genetic information that the molecule carries.

A helpful shortcut our brain makes in scene recognition is to assume that lighting comes from:
Answer: A. Above
Explanation:
Scientists believe that in order for humans to see things, the brain has to make certain assumptions which are done based on previous scenes that it has interpreted before because the eyes do not provide it with complete data. .
One of those assumptions is that light comes from above which is why the shape of a picture can change depending on the lighting in it.
What causes the "plastic" nature of
the asthenosphere?
A. it is mostly water
B. it only found under the ocean
C. constant earthquake activity
D. heat from below
The heat from below causes the "plastic" nature of the asthenosphere. The correct option is D.
What is asthenosphere?The asthenosphere is the upper mantle's mechanically sluggish and ductile region.
It is located beneath the lithosphere, somewhere around 80 and 200 kilometers underneath the surface, and can extend up to 700 kilometers. However, the asthenosphere's lower boundary is not well defined.
Semi-plastic rock makes up the Asthenosphere. Because of Lithosphere has a lower density, it resides on top of the Asthenosphere, much like an iceberg or a block of wood does on water.
The lower mantle beneath the Asthenosphere is stiffer and less plastic. The outer core is located beneath the Mantle.
The "plastic" essence of the asthenosphere is caused by heat from below.
Thus, the correct option is D.
