Answer:
the phenotype is PURPLE
Explanation:
The pea plant will have purple color due to the presence of a dominant allele.
What is the law of dominance?In a heterozygote, one trait will mask the existence of some other trait for the same feature, according to Mendel's rule of dominance. The dominant allele will be expressed only, rather than both alleles contributing to a phenotype. The recessive gene will continue to be "latent," but it will be passed on to progeny in the same way that the dominant allele is.
Only kids with two copies of this gene will exhibit the recessive phenotype; these offspring will reproduce true when self-crossed. Dominant and recessive relate, by definition, to the genotypic interactions of alleles that result in the phenotype of the heterozygote.
The fundamental idea is genetic: which of the two alleles in a heterozygote gets expressed, resulting in an individual that has the same phenotype as one of the two homozygotes. The term "dominant trait" or "dominant allele" is occasionally used to refer to the characteristic associated with the dominant allele and "recessive trait" to the trait associated with the concealed allele. However, this could make it difficult to comprehend the idea of phenotype.
Therefore, the pea plant will have purple flowers due to the presence of a dominant allele.

what differences if any, would assay show if performed using milk that was past its expiration date and had an off-putting odor.
Answer:
The color will disappear.
Explanation:
Due to the absence of oxygen in the expired milk, the actual color of milk disappear. There are certain bacteria such as Pseudomonas present in the milk which is responsible for the change in color. With the passage of time, Pseudomonas starts growing in the milk and release certain toxin which spoils milk. They grow in both condition i. e. in the presence and absence of oxygen. Change in color is due to chemical releases by Pseudomonas.

Which way of organizing DNA best ensure that the information contained on each strand can be accessed
and read?
Why?
NEED ANSWER ASAP SOMEBODY HELP
The information stored in the order of bases is organized into genes: each gene contains information for making a functional product. The genetic information is first copied to another nucleic acid polymer, RNA (ribonucleic acid), preserving the order of the nucleotide bases. Genes that contain instructions for making proteins are converted to messenger RNA (mRNA). Some specialized genes contain instructions for making functional RNA molecules that don’t make proteins. These RNA molecules function by affecting cellular processes directly; for example some of these RNA molecules regulate the expression of mRNA. Other genes produce RNA molecules that are required for protein synthesis, transfer RNA (tRNA), and ribosomal RNA (rRNA).

Answer:
The correct answer is that its activity increases.
Explanation:
Glycogen phosphorylase comes under the category of phosphorylase enzymes. The mentioned enzyme catalyzes the rate-limiting step in the process of glycogenolysis within the animals. The sequential phosphorolysis of glycogen to discharge glucose-1-phosphate is catalyzed by the enzyme glycogen phosphorylase. Therefore, glycogen phosphorylase plays an essential part in the use of liver and muscle reserves of glycogen. After undergoing phosphorylation, the activity of the enzyme increases.
when does mutation have the greatest effect; translation, RNA synthesis, DNA Replication or somatic cell formation?
Answer:
It depends on the specific cell type that suffers the mutation. For example, in stem cells, it is reasonable to expect that mutations in the genes involved in DNA replication will have critical consequences
Explanation:
A mutation is a genetic modification in the DNA sequence due to errors during the mechanism of DNA replication or by the effects of environmental (mutagenic) factors. A mutation in the germline can be inherited in the next generations, while a mutation in somatic cells is not inherited. Moreover, a mutation affecting RNA synthesis may have diverse effects depending on the function of the gene involved in this mutation. In a similar mode, a mutation in one gene associated with the mechanism of DNA replication can have critical consequences on the cells originated from the mutated parental cell, but again it is variable and generalizations can not be made without knowledge of the cell type suffering this modification.

7) We learned that post-transcriptional processing is very important in eukaryotic cells, such as those in our own
bodies. Of what possible advantage could this be to a cell? Name one part of mammalian (including human) function
that relies very much on the 'slicing and recombination that is part of post-transcriptional processing.
Answer:
Alternative splicing is a posttranscriptional modification that enables to produce many proteins from a single gene, thereby increasing its functional diversity. In mammals, alternative splicing has shown to be associated with the control of different signaling pathways in response to environmental conditions.
Explanation:
Posttranscriptional modifications are required for the maturation of primary RNA transcripts, and it is associated with the process of translation into proteins. These types of modifications include the alternative splicing in order to remove introns of pre-mRNA molecules, the addition of a cap to the 5' end and polyadenylation of the 3′ end of mRNAs, etc. For example, the polyadenylation (poly-A) of mRNA tails provide stability to these molecules, thereby they are more resistant to exonucleolytic degradation and thus can be translated into proteins.

(1)Cells, like any factory, need energy to operate.
(2)Two different kinds of cellular power plants have evolved: some cells absorb energy directly from the sun, while others gather energy by eating other organisms that have stored it.
(3)Plants acquire energy directly from sunlight through the process of photosynthesis.
(4)In this process, molecules of chlorophyll or related pigments absorb photons from the sun.
(5)The photons’ energy is converted into chemical energy that the plant can use to grow and reproduce.
(6)In the course of this rather complicated chemical process, carbon dioxide and water from the cell’s surroundings are converted into glucose plus oxygen.
(7)The net effect of photosynthesis, then, is to remove carbon dioxide from the air, produce energy for the cell, and give off oxygen as a waste product.
(8)Animals, unlike plants, cannot convert the sun’s energy directly to food, and therefore must get theirs by eating plants or by eating animals that eat plants.
(9)The food you eat contains energy in the form of the bonds that hold its molecules together.
(10)After the food has been broken down, it is taken into the cells, where its energy is released by a process called respiration.
(11)This process allows molecules like glucose to combine with oxygen, thereby releasing the energy tied up in the molecular bonds.
(12)Its waste product is carbon dioxide, which you breathe out.

Which structure is highlighted? proximal convoluted tubule descending loop of Henle distal convoluted tubule ascending loop of Henle
Answer:
distal convoluted tubule
Explanation:
This is the region of the nephron downstream the macula densa ,which extends the to convulence of the collecting duct.Due to response to mineralocoticoid aldosterone they can be categorised as Distal Convoluted 1 and Distal convoluted 2. This steroid hormones is responsible for homeostatic control of hyperkalemia.
The DCT cells are simple cuboidal epithelium.The stained or pointed part of the image represented this possess this shape,they are therefore portion of DCT. Besides the stained cells are located above the glomerulus ()in the cortex as indicated,therefore they can not be the proximal which must be below the glomerulus, based on the shape ascending and descending loop of Henle (despite located in the cortex too).
The functions of the DCT is in the absorption and secretions of ions(majorly ca+,Na+ and chloride ions.By secreting hydrogen and reabsorbing HC03 ions ,the pH of the urine is maintained.
A farmer plants Bt cotton that is genetically modified to produce its own insecticide. Of the cotton bollworms feeding on these Bt plants, only 8% survive unless they have at least one copy of the dominant resistance allele R that confers resistance to the Bt insecticide. When the farmer first plants Bt cotton, the frequency of the R allele in the cotton bollworm population is 0.4. What will the frequency of the resistance allele be after one generation of cotton bollworms fed on Bt cotton
Answer:
0.6
Explanation:
According to hardy-weinberg principle,
P2+2pq+q2=1
P+q=1
q=1-p
Given that Allele R frequency is 0.4
and p represent the dominant allele
P=0.4
P2=0.4^2 = 0.16 for genotypic frequency
Since p+q=1
q=1-p
where q stands for recessive allele r frequency and q2 stands for genotypic frequency for allele r
q= 1-0.4= 0.6
q2=0.6 ^2
q2=0.36
Hardy-Weinberg principle states that are used to calculate the genetic variation of a population at equilibrium.
The frequency of the resistance allele in the cotton bollworm is 0.6.
Hardy-Weinberg equation can be given as:
P² + 2PQ + Q² = 1
where,
P = dominant allele (R)
Q = recessive allele (r)
Frequency of R allele = 0.4
From the equation:
P + Q = 1
or,
Q = P - 1
Genetic frequency of the R allele = P² = 0.4 x 0.4 = 0.16
Substituting the values:
Q = 1 - 0.4
Q = 0.6
Q² = 0.36
Thus, the frequency of the resistance allele will be 0.6.

Ball-and-socket joints allow this gymnast to complete many of the routines that she performs. A gymnast is shown. In which part of the body is a ball-and-socket joint found? wrist elbow hip knee
Answer:
c
Explanation:
There is a ball-and-socket joint in the hip area of the body. So, the correct option is C.
What is Ball-and-socket joint?The hip is home to the ball and socket joint. It is situated where the pelvic bone and femur (the thigh bone) meet. An example of a ball and socket joint is one in which one bone exactly resembles a ball and another bone precisely resembles a hollow or socket into which the first bone would fit.
This facilitates the bone's mobility in all planes. As a result, the hip has a ball and socket joint and can move in all directions. When compared to other joints, which are found in the fingers, knees, elbows, and toes, ball-and-socket joints, such as those in the shoulder and hip, permit only bending and straightening motions.
