Answer:
letters, allele
Explanation:
The genotype is written as YY, Yy, or yy. The dominant allele is upper case (Y) and the recessive allele is lower case (y). Each letter represents one of the two alleles in the genotype.
Genotypes are written as 2 letters representing each allele for the trait.
What is genotype?The genotype is an organism's genes; for one specific trait, we use two letters to represent the genotype.
A capital letter denotes the dominant form of a gene (allele), while a lowercase letter denotes the recessive form of the gene (allele).
In a bigger way, the term "genotype" recognized to an organism's genetic makeup; in other words, it describes an organism's entire set of genes. In a narrower sense, the term can refer to the alleles, or variant forms of a gene, that an organism carries.
From embryonic formation to adulthood, the genotype determines an individual's hereditary potentials and limitations.
Thus, there are two letters in genotype representing trait for each allele.

not.
C Passive transport does not require energy, but active transport does.
D Passive transport requires carrier proteins, but active transport does not.
Answer:
the first one is F, the permeability. the second is C
Question 4: The permeability of the cell membrane determines the rate at which molecules enter a cell.
Question 5: The statement that describes the difference between passive and active transport is "Passive transport does not require energy, but active transport does"
CELL MEMBRANE:
The cell membrane is the organelle that bounds the cell and its component.The cell membrane is referred to as a semipermeable membrane because it selectively allows the passage of molecules in and out of the cell. However, the rate at which molecules enter a cell is determined by the permeability of the cell membrane. The cell membrane is permeable to some molecules but not permeable to others.CELLULAR TRANSPORT:
The transport of substances in and out a cell can be of two types namely: active transport and passive transport. Active transport is the type of transport that involves the use of energy in form of ATP. In active transport, substance move against a concentration gradient. On the other hand, passive transport does not require energy input because movement of substances occur down a gradient. Therefore, the statement that describes the difference between passive and active transport is "Passive transport does not require energy, but active transport does".Learn more at: https://brainly.com/question/18067330?referrer=searchResults

whats the form of Stereoisomerism?
Answer:
In stereochemistry, stereoisomerism, or spatial isomerism, is a form of isomerism in which molecules have the same molecular formula and sequence of bonded atoms (constitution), but differ in the three-dimensional orientations of their atoms in space. This contrasts with structural isomers, which share the same molecular formula, but the bond connections or their order differs. By definition, molecules that are stereoisomers of each other represent the same structural isomer.

In a cross between two mice that are heterozygous for agouti, black, color, and piebaldism, what is the probability that offspring will have solid black fur along with large patches of white fur? (Hint: Consider each gene separately; then use the multiplication rule. For more help getting started, see Hint 1.)
Answer:
9/256
Explanation:
According to Mendel's experiments the results for the heterozygous are in the ratio 3:1
As each gene is considered separately and the multiplication rule is used. Therefore the probability of getting a solid color would be 1/4 and black fur would be 3/4. Similarly the probability of getting the colored fur is 3/4 and getting a piebald( white patches) is 1/4
Then the combined probability is (1/4*3/4*1/4*3/4)= 9/256

Runoff that contains fertilizers can cause increased levels of nitrogen in the ocean. What is a possible result of these increased nitrogen levels that may have harmful effects that can disrupt the diversity of ocean ecosystems?
Answer:
Explanation:
Increased nitrogen level in ocean water can lead to excessive growth of aquatic plants in the ocean which in turn leads to high oxygen (dissolved oxygen) uptake by these plants when they decompose. The overgrowth of these plants also prevent light penetration in the ocean water. All these can affect other aquatic organisms particularly those that depend on these dissolved oxygen and/or light penetration (such as fish and crustaceans).
In certain fish, blue scales (B) and red scales (R) are codominant. Cross a blue
fish and red fish. What is the genotype of the offspring? What is the phenotype
of the offspring? **
Answer:
the genotype of the offspring would be RB, BR, RB, BR (well the genetic pattern of the fish varies for example the fish could have Bg meaning dominant blue and maybe recessive green im making this up and going into detail too much). the phenotype would have to be some sort of mix.
Explanation:
the genotype is the genes on the inside. i just use a table to mix it and assumed both fish were just pure blue/pure red. the phenotype is what's visible. it would be a mix such as maybe purple or red here and blue there. this is since they are both dominant and have to be expressed. same for blood types (AB blood). sorry for late answer.

Explanation:
The cross over frequency between linked genes C and D is 40%; between A and D is 35%; between C and A is 5%; between A and E is 25%; and between E and D is 10%. Construct a linkage map of these 4 gense and show the distances between the adjacent genes.
Answer: The first line shows the Correct order of genes in the chromosome and the second and third lines show the distances between genes.
C ------------ A ---------------------------------- E -------------------- D (Correct order)
/-----5MU--//---------------25 MU-----------//---------10MU-----/ (Distances)
/------------------------------------40 MU ------------------------------/ (Total distance)
Explanation:
We need to know that 1% of recombination frequency = 1 map unit = 1cm. And that the maximum recombination frequency is always 50%.
The map unit is the distance between the pair of genes for which every 100 meiotic products, one results in a recombinant one.
The recombination frequencies between two genes determine their distance in the chromosome, measured in map units. So, if we know the recombination frequencies, we can calculate distances between the four genes in the problem and we can figure the genes order out. This is:
Recombination frequencies:
1% of recombination frequency = 1 map unit (MU)
C-D = 40% = 40 MU
A-D = 35% = 35 MU
C-A = 5% = 5 MU
A-E = 25% = 25 MU
E-D = 10% = 10 MU
Now that we know the distances between pairs of genes, we need to figure out which is the correct order in the chromosome.
C and D are the genes with the biggest distance between them (40MU), which probably means they are in the extremes. The rest of the genes are in the middle.
C ------------------ (40MU) --------------------------------------- D
A is 5 MU apart from C and 35 MU apart from D, which means it is closer to C.
C------ (5MU)----A------------------------------(35 MU)-------D
E is 25 MU apart from A and only 10 MU apart from D, which means it is between A and D, and closer to D
C--------------------A------- (25 MU)---------E----(10MU)-----D
The sum of C-A distance + A-E distance + E-D distance equals the C-D distance. This is:
C-A 5MU + A-E 25MU + E-D 10MU = C-D 40 MU
5 + 25 + 10 = 40
In conclusion, the correct order of the genes in the chromosome is
C ------------ A ---------------------------------- E -------------------- D
/-----5MU--//---------------25 MU-----------//---------10MU-----/
/------------------------------------40 MU ------------------------------/

Which property of carbon makes it the "building blocks of life"?
Answer:
matter
Explanation:
The property that makes carbon the "building blocks of life" is the ability of carbon to form stable bonds with many elements including itself.
Why carbon is essential for the survival of life?Carbon is essential for the survival of life because it has the ability to form bonds with other elements like oxygen, hydrogen, nitrogen, and even carbon. This property makes essential biomolecules like proteins, carbohydrates, nucleic acids, etc. that are the backbone of living organisms.
This property of forming bonds with other numerous elements permits carbon to form a huge variety of very large and complex molecules like carbohydrates, lipids, etc. Due to this, carbon occupies the title "building blocks of life".
Therefore, the property that makes carbon the "building blocks of life" is the ability of carbon to form stable bonds with many elements including itself.

A student was observing (looking at) a section (part) of cells under a microscope. She noticed (saw) they had a box-like shape, bean-shaped organelles and were green. She also noticed (saw) a nucleus that was to the side of the cell. What was she examining? An Animal Cell A virus A bacterium A plant cell
Answer:
A plant cell.
Explanation:
Plant cells are part of multicellular organisms. They form tissues and are differentiated. If we see a section of plant cells, we can see that they have a box-like shape. This happens because plant cells, besides the membrane, are surrounded by a cell wall, which is rigid and gives the cell this form.
They also do photosynthesis, which is a metabolic process where they obtain energy from the radiation of the sun. To capture the photons they have pigments, especially a green pigment called chlorophyll. The chlorophyll is not free in the cytoplasm, it is contained in a bean-shaped organelle called chloroplast, and therefore they give the chloroplast this distinctive green color.
