Answers

Answer 1

In a forest community, the shelf fungus and the slug live in a mutually beneficial relationship on the side of a decaying tree trunk.

The shelf fungus digests and absorbs materials from the tree, while the slug eats algae growing on the outside of the trunk. This is an example of commensalism, where one organism benefits while the other is unaffected. The shelf fungus benefits from the decaying tree trunk and does not compete with the slug for food since the slug feeds on the algae, which the fungus cannot use. Likewise, the slug benefits from the algae on the tree trunk and does not compete with the fungus since it feeds on a different resource. Therefore, the two organisms are able to coexist in the same habitat without any competition, and each fulfills a different role in the ecosystem.

Putting an antibiotic resistance gene in a recombinant plasmid used for genetic engineering makes: Group of answer choices replica plating possible direct selection possible the recombinant cell dangerous the recombinant cell unable to survive

Answers

Putting an antibiotic resistance gene in a recombinant plasmid used for genetic engineering makes direct selection possible. The correct answer is B.

The antibiotic resistance gene provides a selectable marker that allows researchers to easily identify cells that have taken up the recombinant plasmid and have been successfully transformed.

Direct selection is a process by which cells that have been transformed with the recombinant plasmid can be selected for and grown directly on agar plates containing the antibiotic to which the plasmid provides resistance.

Any cells that have not taken up the plasmid and do not contain the antibiotic resistance gene will be unable to survive in the presence of the antibiotic, while cells that have taken up the plasmid and contain the resistance gene will be able to grow and form colonies on the plate.

This process allows for easy identification and isolation of cells that have taken up the recombinant plasmid, which can then be used for further analysis or genetic engineering.

By including an antibiotic-resistance gene in the recombinant plasmid, researchers can also ensure that the cells they are working with have successfully taken up the plasmid and contain the desired genetic material. Therefore, the correct answer is B.

Answers

The correct answer is c. When the membrane is depolarized, the voltage sensor moves towards the outside of the membrane, allowing opening of the activation gate.

Voltage-gated sodium channels are responsible for the rapid depolarization of the cell membrane during action potentials. These channels contain a voltage sensor that detects changes in membrane potential. The voltage sensor is composed of charged amino acids, such as arginine and lysine. During resting conditions, the voltage sensor is in a closed state and is normally pulled towards the inside of the cell due to its high arginine content. However, when the membrane is depolarized, the voltage sensor moves towards the outside of the membrane, which causes a conformational change in the channel protein, allowing opening of the activation gate. This leads to an influx of sodium ions into the cell, which further depolarizes the membrane and triggers an action potential. Therefore, option c best explains the operation of the voltage sensor in the voltage-gated sodium channel.

3. The daughter inherits one X chromosome from her mother and one from her father. Since the daughter is color-blind, her genotype must be XcXc (both X chromosomes carry the color-blind gene).
4. Knowing that the daughter inherited one Xc chromosome from her father, we can deduce that she must have inherited the other Xc chromosome from her mother.
5. Since the mother is not color-blind, her second X chromosome must be normal (X). Therefore, her genotype for this trait is XcX.

An inhibitor that binds only to the ES complex and not free enzyme is known as a(n) __________ inhibitor.

Answers

An inhibitor that binds only to the ES complex (enzyme-substrate complex) and not the free enzyme is known as an uncompetitive inhibitor.

It works by competing with the substrate for the active site of the enzyme, so that the substrate cannot bind and the enzyme cannot catalyze the reaction. This type of inhibitor works because the enzyme-inhibitor complex is less stable than the enzyme-substrate complex, and so the enzyme-inhibitor complex dissociates more quickly than the enzyme-substrate complex. This means that the enzyme cannot catalyze the reaction, as the substrate cannot bind. Competitive inhibitors can be reversible or irreversible, depending on their chemical structure.
