Describe how positive control in prokaryotes can be altered by the external environment

Answers

Answer:

The positive control is control when there is an activator present which acts as a regulatory protein so the operon and activator binds and initiates the stimulation of transcription to express the gene. In absence of this activator or regulatory protein, the operon will be inactivated.

External environmental stimuli can lead to alteration of the positive control in prokaryotes such as excess lactose in the environment. These environmental stimuli can induce transcription in prokaryotes.

In this example, if glucose is not available in the environment, the transcription of the lac operon will be induced by the presence of lactose in the environment.

What other factors did you modify for BEE? Why do you think you need to consider these factors with caloric intake?

Answers

Answer:

The activity factor was modified. Ambulating indicates that the person is active. Even small activities require energy. So, people who can walk around and aren’t bedridden expend more calories than people who need to be on bedrest all day. Also, when the stress factor was changed to severe infection, the caloric requirement increased. This increase is probably because the immune system requires more energy to fight off the infection

Which of the following statements best describes the role of adenylyl cyclase in
the epinephrine signaling pathway?
A.It converts a polymer to its monomer subunits.
B.It moves substances across the plasma membrane.
ect!
C.It accelerates the production of a second messenger.
D.It transfers phosphate groups from to protein substrates.

Answers

Answer:

C.It accelerates the production of a second messenger.

Explanation:

Adenylyl cyclase is an enzyme that catalyzes the conversion of adenosine triphosphate (ATP) to cyclic adenosine monophosphate (cAMP), a second messenger that activates the protein kinase A (PK-A) protein by dissociation of its regulatory subunit from the catalytic subunit. The first step of the epinephrine signaling pathway consists of the hormone binding to the epinephrine receptor localized on the cell surface. This binding activates a G protein inside the cell, which in turn activates the adenylyl cyclase enzyme. Subsequently, adenylyl cyclase converts ATP molecules into cAMP molecules. Since cAMP transports the message of the epinephrine hormone within the cell this molecule (cAMP) is considered to be a second messenger. Finally, cAMP activates the PK-A enzyme which phosphorylates different proteins and thus triggers different biological processes.

What cell parts are common to What cell parts are found only in plant cells? What are found only in animal cells?
all of these cells?

Answers

Answer:

The organelles found only in plant cells include- chloroplast, cell wall, plastids, and a large central vacuole. The chloroplasts contain a green pigment chlorophyll that is responsible for the process of photosynthesis. What is the composition of a plant cell wall? The cell wall of a plant is made up of cellulose

Animal cells are eukaryotic cells or cells with a membrane-bound nucleus. Unlike prokaryotic cells, DNA in animal cells is housed within the nucleus. In addition to having a nucleus, animal cells also contain other membrane-bound organelles, or tiny cellular structures, that carry out specific functions necessary for normal cellular operation

Answer: the plant cell has a cell wall, chloroplasts, plastids, and central vacuole structures not found in animal cells. Plant cells do not have lysosomes or centrosomes.

Indicate whether a solution will have more OH– or H+ if the pH value of the solution
is 10.

Answers

A pH level of 10 is very alkaline, and one indicator of a solution being an base would be that it was a hydroxide (OH-) therefore the solution would have more OH- .

The solution with a pH value of 10 will have more OH- ions.  

In chemistry, pH is described as a scale that is specifically utilized to specify the basicity or acidity of an aqueous solution. The pH of different solutions are described as follows:

Acidic solution: If a solution has pH<7, then the solution is acidic and tend to have more H+ ions than OH- ions Neutral solution: The solution is neutral when pH=7 and the concentration of H+ and OH- ions are the same Basic solution: If a solution has pH>7, then the solution is Basic and tend to have more OH- ions than H+ ions

Thus, in this case, pH>7 and thus we can conclude that the solution will have more OH- ions than H+ ions.

A group of students wanted to know if millipedes prefer moist or dry environments. They suspected that millipedes would prefer moist environments because they had observed that millipedes are usually found under decaying logs.

Answers

Answer:

The suspicion of the students are very correct. Millipedes prefer damp environments. They need water moisture to survive.

Explanation:

Millipedes are known as arthropods. An Arthropod is an animal without a spinal vertebra, which possesses a segmented body, paired jointed appendages, and an exoskeleton.

They are found to be very ardent and quicker at recycling natural waste than animals and plants.

Without adequate moisture, Millipedes can die within 48 hours.
