Answer:

shorter and higher

Explanation:

UV  is further along in the EM spectrum so has a higher frequency and shorter wavelengths than visible light.

Answer:

Mitosis is the sort of cell division depicted by the processes in C and D.

Explanation:

A short explanation of what Mitosis is: The division of vegetative cells, which culminates in the formation of two genetically identical but independently functioning daughter cells.

Sister chromatids separate into opposing poles during mitosis in anaphase, and each group of chromatids forms the genetic materials for daughter cells that will become independent when the parent cell undergoes cytokinesis or cytoplasm division.

Diagram:

The letter C in the illustration represents the mitotic metaphase when chromosomes congregate in the center of the cell and are connected by spindle fibers.

D is the anaphase in which sister chromatids are separated and begin to move to oppose poles due to spindle fiber contraction.

Musculst arteries vessels increase peripheral resistance when they vasoconstrict in resporise to epinephrine and norepinephrine. Hence, the correct option is (c).

The vessels that increase peripheral resistance when they vasoconstrict in response to epinephrine and norepinephrine are the muscular arteries. These arteries have a thick layer of smooth muscle in their walls, which allows them to constrict or dilate in response to various stimuli. When the sympathetic nervous system is activated, it releases norepinephrine and epinephrine, which bind to alpha-adrenergic receptors on the smooth muscle cells in the walls of the muscular arteries. This causes the smooth muscle cells to contract, leading to vasoconstriction and an increase in peripheral resistance. Vasoconstriction of the muscular arteries helps to maintain blood pressure during times of stress or physical activity. By constricting the arteries, the body can redirect blood flow to areas where it is needed most, such as the muscles, heart, and brain. However, chronic vasoconstriction of the muscular arteries can lead to hypertension (high blood pressure) and increase the risk of cardiovascular disease. Therefore, it is important to maintain a healthy lifestyle and manage stress to help prevent chronic vasoconstriction of the muscular arteries.

Annull mutation in which of these genes would cause ABC protein to be produced at normal levels but in the wrong location is MP. The main answer is MP.

ABC gene produces mRNA encoding the ABC protein, and ZBP1 protein binds Abc mRNA and prevents its translation. MP (motor protein) transports ZBP1-bound mRNA to its destination, while Src protein is located at the destination and causes ZBP1 to dissociate from mRNA, allowing it to be translated.

In a mutation, the characteristics of DNA are altered, resulting in different genes being expressed or the production of altered proteins. A mutation in the MP gene can cause the protein to be produced at normal levels but in the wrong location. As a result, mRNA bound with ZBP1 would not be transported to its destination.

The type of mutation that would interfere with the attenuation mechanism in the tryptophan operon is the deletion mutation. In the tryptophan operon, the attenuation mechanism is used to regulate the synthesis of tryptophan. When the tryptophan levels are low, the operon is activated, and transcription takes place, allowing the synthesis of tryptophan. When tryptophan levels are high, the attenuation mechanism is activated, and transcription is halted. A deletion mutation, which removes one or more nucleotides from the DNA sequence, can interfere with the folding of RNA, resulting in a premature termination of transcription, which will cause attenuation to fail.

The expected rate of return of Freedman Flowers is 9.9%.

Expected rate of return is the sum of the multiplication of each possible return with its corresponding probability of occurrence. Freedman Flowers' stock has a 50% chance of producing a 25% return, a 30% chance of producing a 10% return, and a 20% chance of producing a -28% return. The expected rate of return of Freedman Flowers can be calculated as follows:

Expected rate of return = (Probability of return 1 × Return 1) + (Probability of return 2 × Return 2) + (Probability of return 3 × Return 3)

Therefore, the expected rate of return of Freedman Flowers is:

Expected rate of return = (0.5 × 25%) + (0.3 × 10%) + (0.2 × -28%)

Expected rate of return = 12.5% + 3% - 5.6%

Expected rate of return = 9.9%

Therefore, the expected rate of return of Freedman Flowers is 9.9%.Option B, 9.9006 is the closest to the calculated expected rate of return.

C. The cell membrane lets the materials into the cell so they can get to the mitochondria

Explanation:

The cell membrane regulates the entrance and exit of certain molecules inside the cell. Some molecules can easily pass through the phospholipid bilayer via passive transport. Others use protein channels, and some require movement by active transport, or endocytosis.

Answer: Given this statistic, it is not surprising that the primary control point for gene expression is usually at the very beginning of the protein production process — the initiation of transcription. RNA transcription makes an efficient control point because many proteins can be made from a single mRNA molecule.

Yes, it is possible for real populations to increase quickly under certain conditions. Populations with high reproductive rates, short generation times, and abundant resources can experience rapid growth. For example, bacteria can reproduce rapidly under favorable conditions, such as in a nutrient-rich environment with a stable temperature and pH. Additionally, some species of rabbits are known for their high reproductive rates, with females being able to give birth to multiple litters in a single year. However, it's important to note that population growth is not always sustainable, and can be limited by factors such as limited resources, predation, and disease. In the case of bacteria, they may also experience competition for resources and the buildup of toxic waste products, which can limit their growth.

When the spliceosome binds to a pre-mRNA transcript, it typically attaches at certain sequences along an intron.

What is a spliceosome?

The spliceosome is a complex composed of RNA and protein molecules that removes non-coding introns from the pre-mRNA transcript in the process of gene expression. Splicing is necessary to generate mature mRNA transcripts that can be translated into proteins.

Eukaryotic cells often have a large ribonucleoprotein (RNP) complex known as a spliceosome. These cells are classified as eukaryotic. A large number of proteins and short nuclear RNAs (snRNA) are required for the assembly of the spliceosome.

What is the process of splicing?

Splicing begins with the binding of U1 snRNP to the 5' splice site of the intron. U2 snRNP then joins the spliceosome, followed by other factors, resulting in the formation of an active spliceosome that catalyzes the splicing reaction.

After cleavage at the 5' splice site, the intron forms a lariat structure, and the spliceosome cuts the RNA at the 3' splice site. The exons are then spliced together to produce mature mRNA.

Therefore, when the spliceosome binds to a pre-mRNA transcript, it typically attaches at certain sequences along an intron.
