You create a punnett square to determine the probability of hair color being passed to
offspring. Brown hair is dominant. Blond hair is recessive. Both parents have brown hair.
Both parents are heterozygous. What is the probability that the offspring will also have
brown hair?
ofteprings Brown hair to de
Answers
Answer:
75%, or 3/4's
Explanation:
Parent's genotypes are Bb because they are homozygous & brown hair is dominant. Cross this, and you get the genotypes of the offspring: BB, Bb, Bb, and bb. The proability that offspring will also have brown hair is 3 out of these 4 genotypes, so 75%.

Which of these is an example of genetic modification:

c. Getting a flu shot
d. Adding a gene for mold resistance to corn DNA
Answers
Answer
D, genetic modification is a technique to change the characteristics of a plant, animal or micro-organism by transferring a piece of DNA from one organism to a different organism.
Explanation:
(mark as brainliest please)
Changes in genetic data lead to gene modification. Adding a gene for mold resistance to corn DNA is an example of genetic modification. option D is the correct answer.
What is genetic modification?
Genetic modification is a process in which the genes of an organism are modified. This can be done by base insertion or deletion or by any other environmental factor. Genetic modification can be done artificially. CRISPR-Cas9, gene editing, etc. are some examples.
This is done to get more productivity in crops, to reverse a genetic disease, etc. An example is adding a gene for mold resistance to corn DNA. Due to this gene modification, the corn will produce some proteins that will protect it from mold attack. Other options are not correct for the statement, as there is no change in gene activity.
Hence, the correct option is to add a gene for mold resistance to the corn. Option D is the correct answer.

The p53 protein is a transcription factor that regulates a cell's progression through the cell cycle after DNA is damaged by ultraviolet ( UV ) radiation. The p53 pathway is shown in Figure 1.
Please answer this question! I will give brainliest!
Please note: p53 regulating image is for the entire problem, whereas part C image is only for part C.
(a) A skin cell completes one round of the cell cycle. Describe the products.
(b) Based on Figure 1, explain how p53 regulates the cell cycle in the presence of damaged DNA .
(c) Draw an X on the template in the space provided for your response to indicate the phase during which the replication of damaged DNA would occur.
(d) Based on Figure 1, explain how a mutation to p53 may lead to an increased risk of cancer.
Answers
Answer:
(a) Since skin cells undergo the process of mitosis, the product of one cell cycle is 2 identical daughter cells.
(b) The levels of p53 protein in the cell will rise in response to DNA damage. This will stop the cycle at one point to give time to the repair machinery to regain stability. As can be seen in the figure, CDK inhibitors have been produced which are responsible for halting the cell cycle.
(c) The S phase (synthesis phase) is when replication of damaged DNA would occur.
(d) p53 responds in one of 3 ways to an event of DNA damage: arresting the cell-cycle, apoptosis (programmed cell death), or repairing the DNA. If there has been a mutation in p53, neither of the three way would take place to prevent more copies of damaged DNA being made. A mutated p53 protein would no longer be able to suppress tumors.
Hope that answers the question, have a great day!
The cell cycle is the process in which a cell undergoes four phases of division to give rise to daughter cells.
(a) The skin cell is a type of somatic cell, which undergoes mitotic division. The products of the cell cycle will be two identical daughter cells.
(b) p53 is a transcription factor, which will halt the replication if any error occurs. CDK inhibitors are produced in the cycle, which regains stability and activates the repair mechanism.
(c) The synthesis phase or S phase of the cell cycle is the site where replication of the DNA occurs. It takes place after the G1 phase.
(d) p53 transcription factor can arrest the cell cycle, cause apoptosis, and repair the cell damage. The mutation in the p53 gene can work in any fashion to prevent more damaged copies of the DNA. The mutation in p53 will lead to tumors.

Assume that producers in an ecosystem have 1,000,000 kilocalories of energy. How much energy is available to primary
consumers?
5. Which trophic level has the greatest biomass?
Answers
Therefore, according to this question, if it is assumed that that producers in an ecosystem have 1,000,000 kilocalories of energy; 10/100 × 1,000,000 = 100,000 kilocalories of energy will be available to primary consumers.
WHAT IS BIOMASS:The total biomass of an organism in each trophic level decreases going up. This is due to the lesser energy transferred from one trophic level to the next. As the trophic level increases, lower energy is available to convert into biomass. Hence, the higher the trophic level, the lower the biomass.Therefore, if this is the case, the producers at the first trophic level will contain the greatest biomass which will decrease as the food chain progresses upwards.

A complex molecule containing the genetic code
Answers
Answer:
The terms are not included in the question but their terms are:
Gene- a segment that contains the information for making proteins
DNA- A complex molecule containing the genetic code
Explanation:
All living organisms contains genetic material (containing genes) in their cells. A gene is a segment of DNA that encodes the information needed for the synthesis of certain functional products called PROTEIN. The genes undergo expression i.e. transcription into RNA and translation into protein. This protein is responsible for the phenotype living organisms exhibit.
The genetic material in most organisms is the DNA, which is a complex molecule and one of the two types of nucleic acids containing long polynucleotide chains. The DNA stores the genetic information needed for the expression of genes i.e. genetic code. The information are stored in the four nucleotide bases (Adenine, Guanine, Cytosine and Thymine) that constitutes the DNA.
