What pH rises above 11, the enzyme no longer functions. That is option A.
What is an enzyme?An enzyme is defined as a biological protein that has the ability to increase the rate of a chemical reaction but remains unchanged at the end of the reaction.
The factors that affects an enzyme include the following:
Concentration of Enzyme.Concentration of Substrate.Effect of Temperature.Effect of pH.Effect of Activators.Enzymes mainly work in pH scale of 7.4. Some enzymes which are acidic enzymes work on acidic pH which is 1 to 6 while some enzymes which are basic enzymes work in basic pH such as 8 to 14.
From the graph given, the enzyme functions optimally at pH of 7 but denatures as the pH increases to 11.
Therefore, the enzyme would stop catalysing the reaction as the pH rises to 11.

which of the following is a nonpoint source of water pollution? group of answer choices a sewage treatment plant an electric power plant a factory an active or inactive coal mine a logged forest
Answers
A logged forest is the non-point source of water pollution.
What is water pollution?
When dangerous substances—often chemicals or microorganisms—contaminate a stream, river, lake, ocean, aquifer, or other body of water, their quality deteriorates and they become toxic for both humans and the environment. This is known as water pollution.
Forests can act as runoff buffers, minimizing alterations to the water quality caused by nonpoint sources. Streamside vegetation removal, road building and use, timber harvesting, and mechanical tree planting preparation are all sources of nonpoint source (NPS) pollution related to forestry activities.
Hence the correct answer is a logged forest.

A dormant protective structure that can form in adverse or normal conditions is called?
Answers
A dormant protective structure in bacteria that can form in adverse or normal conditions is called an endospore.
Endospore is a condition in which resistant spore forms inside some bacteria and serves as a shield against harmful conditions. Endospore-forming bacteria are called gram-positive bacteria and can survive under harsh conditions.
In their survival mechanism, gram-positive bacteria divide within the cell and produce intracellular spores which are resistant to harsh conditions. On the other hand, instead of showing development bacteria decide to stay dormant for a while and even longer if the conditions are unfavorable such as low temperature.
However, if the conditions become favorable they resume their growth again.
The conditions that endospores can survive include environmental stress and heat, high temperature, and chemical damage.

cyanide binds strongly with the last electron carrier in the chain. how would this affect the flow of electrons?
Answers
Cyanide binds strongly with the last electron carrier in the chain, this would affect the flow of electrons as- the flow would cease and the ATP production would stop.
In the electron transport chain, the toxin cyanide attaches to an electron carrier and prevents electrons from moving. Glycolysis and the citric acid cycle soon come to an abrupt stop when this occurs.
By blocking the mitochondrial ferricytochrome oxidase system and other enzymes, cyanide prevents cells from using their electron transport system and respiring normally. Cellular hypoxia and lactic acidosis are the results of this.
Cyanide has long been known to bind to the heme a3 prosthetic group in Complex IV, inhibiting mitochondrial electron transport (Cytochrome C oxidase [CCOx]).
Hence, when Cyanide binds strongly with the last electron carrier in the chain, this would affect the flow of electrons as- the flow would cease and the ATP production would stop.

In a cell undergoing meiosis, if homologous chromosomes are aligned at the equator of the meiotic spindle, what process has occurred?.
Answers
The homologous chromosomes are positioned in the center of the cell during metaphase I, with the kinetochores facing the opposite poles. The homologous pairs randomly align themselves with the equator.
What happens first in metaphase?When the duplicated chromosomes are in the cell's core, metaphase I begins. During metaphase I of meiosis, the tetrads align themselves along the cell's center. Because the tetrads have remained intact, each cell will receive one chromosome from each homologous pair during the first division.
What makes metaphase important?Sister chromatids are more evenly distributed amongst the two daughter cells as a result of this. The cell will stop growing if there is an alignment issue or a difficulty with the spindle attachment.

The functions of the rough endoplasmic reticulum include_______
Answers
The functions of the rough endoplasmic reticulum include - Protein synthesis, Glycoprotein synthesis, Protein sorting.
Rough endoplasmic reticulum
Rough endoplasmic reticulum (RER), a network of interconnected flattened sacs that is an organelle with a continuous membrane found in the cytoplasm of eukaryotic cells and is essential for protein production.
The nuclear envelope, which envelops the cell nucleus, is continuous with the RER membrane. The Golgi apparatus, which transports, transforms, and packages proteins for delivery to specific locations, is situated close to the RER. The RER produces a large number of proteins, which are then transferred to the Golgi apparatus in vesicles.
The RER is linked to numerous functions in protein production, including sorting, folding, and post-translational modifications. The mature mRNA transcript is translated by membrane-bound ribosomes in the RER into amino acids, which are then joined to form polypeptides.

Answers
1. The type of receptor that triggers multiple transduction pathways at once is a ligand-gated ion channel. Option A.
2. This receptor was blocked or deactivated Pheomelanin production would increase. Option B.
The binding of the ligand to the receptor indirectly activates adenylyl cyclase, converting ATP to cAMP. cAMP binds and activates protein kinase A allowing PKA to phosphorylate downstream factors and induce cellular responses. Cell Surface Receptors: These receptors are also known as transmembrane receptors.
These are proteins found on the surface of cells and across the plasma membrane. Receptor inactivation can occur in a variety of ways, including target cell degradation or sequestration and removal of ligands by desensitization. The binding of ligands to receptors is a reversible process as the ligands can eventually dissociate from the receptor and be degraded.

Suppose cellular respiration occurs inside an insulated, sealed container. How does the container’s weight change during the reaction?.
Answers
If the cellular respiration occurs in an insulated, sealed container, then the container's weight will not change during the reaction due to the law of conservation of mass.
Cellular respiration is the process of breakdown of food material, especially glucose to release energy, which is used to perform the several other life processes in the body.
The law of conservation of mass states that mass can neither be created nor be destroyed it can only be transferred from one form to another. And this is why the mass of the insulated container will remain constant. An insulated material is the one in which no exchange of mass or energy occurs.

A comparison often made between solids and plasmas is based on their densities. How would you describe the density of a plasma?.
Answers
The density of plasma is Low density.
Plasma is slightly different from other phases of matter because the high temperature breaks atoms particles into electrons and nuclei. This mixture of electrons and nuclei behaves like gas particles, moving freely and having no definite arrangement. For example, plasmas are excellent conductors of heat and electricity because free electrons are very mobile.
Plasma is unique in its interaction with electric and magnetic fields. The movement of free electrons creates an electric current in the plasma. Aurora's lightning and arc welding are also plasmas.
