In microscopy, the ability to distinguish two objects separated by a small distance is called ________________.
Nesterboy [21]

Answer:

The correct answer is "resolution".

Explanation:

The resolution is one key feature that a microscope must have in order to differentiate among microscopic structures that are very close to each other. Resolution is defined as the shortest distance between two points that can be distinguished as two separate structures under the microscope. Therefore, the ability to distinguish two objects separated by a small distance is called resolution.

When an action potential reaches the end of an axon, the – release neurotransmitters. These bind to receptors on the – neuron. E
steposvetlana [31]

Answer:

When an action potential reaches the end of an axon, the nervous terminal or the varicosities release neurotransmitters. These bind to receptors on the postsynaptic neuron. Eventually, the neurotransmitters are removed from the synapse. Some are reabsorbed by the presynaptic neuron or sending neuron, a process called reuptake, and some are broken down, in a process called enzymatic degradation.

Explanation:

Neurotransmitter liberation occurs from the nervous terminal or varicosities, in the neuronal axon. There are vesicles in the sending neuron that have neurotransmitters in their interior. When an <em>action potential reaches the nervous terminal</em> or the varicosities, it occurs a notable increase in the <em>neurotransmitter liberation</em> by exocytose. This is possible because calcium channels open letting the ion in the cell through the membrane, and letting the neurotransmitter out to the synaptic space. The molecule binds to its receptor in the postsynaptic neuron. This receptor is a <em>protein structure that triggers an answer</em>. As long as the signal molecule is in the synaptic space, it keeps linking to its receptor and causing a postsynaptic answer.  <em>To stop this process</em>, the <em>neurotransmitter must be taken out from the synaptic space.</em> There are two mechanisms by which the neurotransmitter can be eliminated:

Enzymatic degradation/deactivation: In the synaptic space, there are <em>specific enzymes that can inactivate the neurotransmitter </em><em>by breaking it down or degrading it</em><em>.</em> In this case, the new molecule won’t be able to bind to the neurotransmitter receptor.

Reuptake: There are receptors located in the presynaptic membrane that can capture de molecule to store it back in new vesicles, for posterior use. These <em>transporters are active transport proteins</em> that easily recognize the neurotransmitter.

During the process of photosynthesis,
TEA [102]

Answer:

d. less than 100% of the energy captured from sunlight is transformed into potential energy in the form of a hydrogen ion gradient and then into potential energy in the form of covalent bonds

Explanation:

Photosynthesis is process utilized by plants, several bacteria and protists to convert the light energy to chemical energy. So they utilize the photosynthesis as the powerhouse for the energy production. Heterotrophs like human that cannot synthesize their own food, use this converted form of energy by autotrophs.

During the light reaction of photosynthesis the photons from light are absorbed by photosystem I and II. These photons excites the electrons which flow through the electron transport chain from higher potential to lower potential. These electrons release the energy while moving from higher potential to lower potential which is utilized by H+ pump to pump the H+ to lumen of plastids from stroma and of course not the 100% energy is utilized some of the energy dissipates. . So this process causes the accumulation of high potential H+ ions across the membrane. These H+ ions are utilized for the production of ATP by ATP synthase complex when they flow back to lower potential across the membrane through ATP synthase complex.

The ATP and NADPH produced from light reaction are utilized to combine carbon molecules during dark reaction. The covalent bond is used to combine the carbon molecules and we know that combining carbon molecules stores energy in the form of covalent bond.

You inherited your mother's crooked nose and her recipe for chocolate chip cookies (both favorable traits). Which trait will be
SIZIF [17.4K]

Answer:

b.the recipe because it can be passed on to all relatives

Explanation:

A crooked nose is a genetic trait and can be passed to the progeny via genes only. Sexually reproducing organisms such as humans experience segregation of traits during gamete formation. Therefore, crooked nose inheritance is a chance factor regulated by the inheritance of genes and the segregation of alleles. On the other hand, a recipe for chocolate chip cookies can be shared with all the relatives and other individuals of the population by any means without any conditions. Therefore, a recipe will spread more quickly through the population.
