Which of the alleles for the OCA2 gene is dominant? Which is recessive?
Answer:
Dominant is the regular colored skin or melanin, and the recessive is albinism
For the OCA2 gene, dominant allele is the regular colored skin or melanin, and the recessive is albinism.
What are the functions of OCA2 genes?The OCA2 gene provides instructions for making a protein called the P protein. This protein is located in melanocytes, which are specialized cells that produce a pigment called melanin.
Several common variations in the OCA2 gene reduce the amount of functional P protein that is produced. Less P protein means that less melanin is present in the iris, leading to blue eyes instead of brown in people with a polymorphism in this gene.
OCA2 is the most common type of albinism in African Black OCA patients. The overall prevalence of OCA2 is estimated to be 1:36,000 in the USA, but is about 1:10,000 among African Americans.

When a tall plant is crossed with a short plant, some of the offspring are short. What are the genotypes of the parents and the offspring? What is the phenotypic result in the offspring?
Answer:
Tall plant with genotypes Pp.
Explanation:
Make the question into a box represented what you are crossing and and the parents genotypes look like.
PP - Tall Plant
Pp - Tall Plant
pp - Short Plant

If a frog cell with 2n = 26 undergoes mitosis one of the daughter cells would have _____ chromosomes and if that frog cell with 2n = 26 undergoes meiosis one daughter cell would have ____ chromosomes?
-------
A.) 13 – 13
B.) 26 – 26
C.) 26 – 13
Answer:
C.) 26 - 13
Explanation:
During mitosis, DNA is replicated during the S phase so that when the cell divides the daughter cells will have the same number of chromosomes that the parent cell had.
DNA replication also occurs during meiosis, but the cell divides twice, so the daughter cells will have half the number of chromosomes that the parent cell had. This is because the daughter cells are sex cells, which combine with another sex cell (either an egg or a sperm) to form one cell with a combined chromosome number.

In DNA what is the complementary strand to GGACG?
Answer:
CCTGC
Explanation:
Adenine (A) and Thymine (T) are base-pairs whilst Cytosine (C) and Guanine (G) are base-pairs as well. Although they only go in the order A-T and C-G, you will never see Adenine and Cytosine together on a DNA strand.
Which biological scenario(s) best describes phenotypic plasticity for a trait?
I. Each person has a specific blood type.
II. Red blood cell counts differ in higher altitudes.
III. One identical twin is taller than the other.
A)I only
B)II only
C)II and III only
D)I, II, and III
Answer:
C) II and III only
Explanation:
Option 1 is not an example of phenotypic plasticity because each person is born with their own blood type and this doesn't change based on their environment and behavior.
Option 2 is an example of phenotypic plasticity because a person's red blood cell counts can increase based on their environment, i.e. moving to Denver, CO from Death Valley, CA. The higher elevation and decreased oxygen causes your body to produce more red blood cells.
Option 3 is an example of phenotypic plasticity because one twin can be taller than another because of differing behaviors, environments, etc.

A) All fish within the species always have the same number of spines,
B) This kind of spiny fish does not have many predators in its habitat,
C) The habitat of the fish must be going through a rapid change over time,
D) The greater number of spines provides some advantage to the fish,
(help please I gotta submit this soon)
Answer:
The answer is D. The Greater number of spines provides some advantages to the fish.
A reasonable conclusion from this observation is the greater number of spines provides some advantages to the fish. The correct option is D).
What are fossil records?Paleontologists, archaeologists, and geologists use the fossil record to put major events and species in the correct geologic epoch. It is based on the Law of Superposition, which stipulates that the bottom layers in undisturbed rock sequences are older than the top layers.
Fossils give vital evidence for evolution and plant and animal adaption to their habitats. Fossil data documents how creatures evolved and how this process can be represented by a 'tree of life,' demonstrating that all species are connected to one another.
Therefore, the correct option is D) The greater number of spines provides some advantage to the fish.

A student creates a list of characteristics for a human cell and a virus. 1. smaller than an organelle 2. absence of metabolic activity 3. grows by dividing 4. presence of enzymes in the cytoplasm 5. surrounded by a protein coat Which characteristics are associated only with a virus? O 1, 2, and 3 O 1,2, and 5 O 2,3, and 4 O 2,3, and 5
Answer:
1, 2, and 5
Explanation:
Viruses are pathogenic microorganisms that lack the ability to thrive and reproduce outside of a living host cell. Their structure is simple - they consist of a nucleic acid molecule surrounded by a protein coating and sometimes an outer envelope. They are too small to be seen by a light microscope.
As they are way smaller than living cells, viruses are smaller than organelles as well. They don't have their own metabolism. Their reproduction is not based on division. They don't have any organelles, including the cytoplasm. They are surrounded by a protein coat called the capsid.
Based on this information, we can see that the correct statements are statements 1, 2, and 5.

All of the following are reasons for regulation of gene expression in eukaryotes EXCEPT -
Answer:
i thinnk its d
Explanation:
The main reason for regulation of gene expression in eukaryotes is cell repair and replacement.
What is gene regulation?Gene regulation is the process used to control the timing, location and amount in which genes are expressed. The process can be complicated and is carried out by a variety of mechanisms, including through regulatory proteins and chemical modification of DNA.
Regulation of gene expression, or gene regulation, includes a wide range of mechanisms that are used by cells to increase or decrease the production of specific gene products.
Hence, gene expression is controlled on two levels. First, transcription is controlled by limiting the amount of mRNA that is produced from a particular gene. The second level of control is through post-transcriptional events that regulate the translation of mRNA into proteins.
