which type of half-cell, when used along with a mn/mn2+ half-cell, gives the largest cell potential?
Answer: the options are not given, here are the options.
A. Cu2+/cu
b. Pb2+/Pb
c. Zn²+Izn
d. The potential for all three cells is the same.
The correct answer is A.
Cu2+/cu
Explanation:
A voltaic or galvanic cell is a cell that uses electrochemical energy generate from oxidation reduction reaction to produce electricity.
In this reaction manganese will be the anode and the Copper will be the cathode.
The half-cell reactions are given below and their respective cell potential.
Mn +Mn2+ + 2e- E°=-1.18v
Zn +2e=Zn E°=-0.76v
Pb+ +2r= Pb E° -0.13
Cu2+ + 2e= Cu E° 0.34
In solving the potential of the cell
E°cell= E° cathode -E°anode
For Mn and Cu.

Two replication forks are formed by the opening of the double-stranded DNA at the origin, and helicase separates the DNA strands, which are coated by single-stranded binding proteins to keep the strands separated. DNA replication occurs in both directions
Which age structure diagram shows that the number of individuals decreases
steadily with age?
Slow Growth
Negative Growth
Stable Growth
Rapid Growth
Answer:
Slow Growth
Explanation:
The age structure diagram is a method of understanding the population. It is used by the demographers to estimate the growth, fall, or change in the population of an area. The data required is the distribution of the age and the sex of an area. When the diagram is constructed and made into a pyramidal shape, it represents that there is a rise in the population of the area. a stable population can be estimated by there is straight up and down. The rapid growth model represents a rapid decrease in the population with age. The slow growth model represents a steady decrease in the population with age
Which of the following is an efferent neuron that is responsible for releasing a neurotransmitter that stimulates a muscle cell to contract?
a) Motor neuron
b) Sensory neuron
c) Interneuron
d) Neuroglia
Answer:
A. Motor Neuron
Explanation:
Motor neurons which can also be referred to as the lower/alpha motor neurons, furnishes skeletal muscle and causes the muscle to contract, this thereafter generates movement. Motor neurons releases neurotransmitter acetylcholine at the neuromuscular junction that stimulates muscle cells to contract.
At the point when the acetylcholine ties to acetylcholine receptors on the muscle fiber, an activity potential is proliferated along the muscle fiber in the two ways. The activity potential triggers the contraction of the muscle. On the off chance that the end of the muscle are fixed, keeping the muscle at a similar length, at that point the compression results on an expanded power on the backings which is referred to as isometric contraction. On the off chance that the muscle abbreviates against no obstruction, the constriction brings about steady power which is referred to as isotonic contraction. The engine neurons that control appendage and body developments are situated in the front horn of the spinal line, and the engine neurons that control head and facial developments are situated in the engine cores of the brainstem. Despite the fact that the engine framework is made out of various kinds of neurons dispersed all through the CNS, the engine neuron is the main manner by which the engine framework can speak with the muscles.
Ultimately, every movements will rely on the activity of the alpha motor neurons.
How is carbon dioxide released into the atmosphere during the carbon cycle
Answer:
Each time you exhale, you are releasing carbon dioxide gas (CO2) into the atmosphere. Animals and plants need to get rid of carbon dioxide gas through a process called respiration. Carbon moves from fossil fuels to the atmosphere when fuels are burned. The carbon is dissolved into the water.
Explanation:
Which statement describes prey? They provide energy for dead organisms. They are killed by predators for energy. They obtain energy from dead organisms. They obtain energy from predators.
Answer:
the answer is B
Explanation:
The statement that describes prey is they are killed by predators for energy. The correct option is b.
What are prey and predator?Predators are often carnivorous creatures that hunt smaller animals for food. Predators hunt, capture, and eat the animals that make up their prey. When there are more predators in a particular environment, there will be less prey overall.
Predators lose population when they move to new locations in search of food, which increases the population of prey in the area from which they migrated. In other words, a cycle of events starting with a decrease in prey and ending with an increase in prey results from an increase in predators.
Therefore, the correct option is b, They are killed by predators for energy regarding the statement that describes prey.

Answer:
The correct answer is option a. "Plasmodial slime mold".
Explanation:
Plasmodial slime molds, are comprised of a single "supercell" with thousands or millions of nuclei within it. These organisms are formed by the fusion of multiple flagellated cells. The formation of these single celled organisms depend on the presence of enough food source. Typically, plasmodial slime molds have a diameter of 3 to 4 centimeters, but they can growth up to 30 centimeters.

The mechanism that accounts for high frequencies of sickle cell hemoglobin in malarial environments is:
Answer:
Selection -Selective advantage
Explanation:
Sickle cell hemoglobin result from the sickle shape of red blood cell instead of the ameboid shaped cell.
Malaria is a deadly disease that result from mosquito bites.
Sickle cell hemoglobin has a selective advantage because of the presence of AS genotype, the s allele in a sickle cell is an harmful recessive allele that remains in the gene pool it becomes expressed when the s allele is expressed in SS form after an AS individual have mated with either an AS or SS individual.
AS genotype has a high resistance against malaria, they have the ability to thrive making the allele s that is recessive for sickle cell thrive well in the environment of malaria in an AS individual.
