Why can information only pass in one direction across synapse?? pls help !!

Answers

A Nerve electrical impulse only travels in one direction. There are several reasons nerve impulses only travel in one direction. The most important is synaptic transport.
In order for a "nerve impulse" to pass from cell to cell, it must cross synaptic junctions. The nerve cells are lined up head to tail all the way down a nerve track, and are not connected, but have tiny gaps between them and the next cell. These tiny gaps are called synapses.
When you get a nerve firing, you have probably heard that it is an electrical impulse that carries the signal. This is true, but it is not electrical in the same way your wall outlet works. This is electrochemical energy. Neurotransmitters are molecules that fit like a lock and key into a specific receptor. The receptor is located on the next cell in the line. When the neurotransmitter hits the receptor on the next cell in line, it signals that cell to begin a firing as well.
This will continue all the way down the length of the nerve track. In a nutshell, a nerve firing results in a chain reaction down the nerve cell's axon, or stemlike section. Sodium (Na+) ions flow in, potassium (K+) ions flow out, and we get an electrochemical gradient flowing down the length of the cell. You can think of it as a line of gunpowder that someone lit, with the flame traveling down the length of it. Common electrical power is more like a hose full of water, and when you put pressure on one end, the water shoots out the other.
Therefore, nerve impulses cannot travel in the opposite direction, because nerve cells only have neurotransmitter storage vesicles going one way, and receptors in one place.

What diagram demonstrates how crossing-over contributes to genetic variety during meiosis?

Answers

Answer:c

Explanation:trust me

The diagram that demonstrates how crossing-over contributes to genetic variety during meiosis is diagram C.

Crossing over refers to the recombination or interchange of genetic material.

This process (crossing over) occurs between non-sister chromatids during meiosis.

Crossing over specifically occurs in the prophase I of meiosis.

A black hybrid rabbit is crossed with a white purebred rabbit.

What is the probability of an offspring being black?
A. 25%
B. 50%
C. 75%

Answers

Answer

A. 25%

Explanation:

This is because the black hybrid would be 50% one breed and 50% another breed. Then the white purebred is 100% one specific breed. So by mating, all of those breeds that the parents have all reduce by 1/2 for the offspring.

25% I’m pretty sure :)

How was early Earth's atmosphere different from today's atmosphere?​

Answers

Answer:

The early Earth was very different from our Earth today.

Explanation:

Earth's first atmosphere had lots of water vapor but had almost no oxygen. Later, frequent volcanic eruptions put several different gases into the air (Figure 12.13). These gases created a new type of atmosphere for Earth.

Answer:

The atmosphere we enjoy today is radically different from the atmosphere that formed with the Earth billions of years ago. ... As the Earth cooled enough to form a solid crust (4.4 billion years ago), it was covered with active volcanos. These volcanos spewed out gasses, like water vapor, carbon dioxide and ammonia.

How has the Earth's atmosphere changed over time?

Water vapor, carbon dioxide, methane, ammonia, and other gases similar to the ones produced by volcanoes today were expelled. Over a vast amount of time, millions of years, the earth gradually cooled. ... From these clouds, the oceans formed and the oceans absorbed a lot of the carbon dioxide in the atmosphere.

Which of the following explains why an apple looks red? The apple reflects red light and absorbs all other visible wavelengths. The apple absorbs red light, and reflects all other colors of light.. The apple is absorbs all visible wavelengths, but absorbs red light better The apple is reflects all light that hits its surface.​

Answers

Answer:

The apple reflects red light and absorbs all other visible wavelengths

Explanation:

The apple is only reflecting the color red and is absorbing the other colors of light (wavelengths)

The correct explanation why an apple looks red is that the apple reflects red light and absorbs all the other visible wavelengths. Thus, the correct option is A.

What is Absorption and reflection of light?

Light absorption is the process in which the light ray is absorbed by the matter and converted into a form of energy. In an atom, the electrons vibrate at a specific frequency, then this is called as the natural frequency.

Reflection is a phenomenon of light. When a ray of light approaches a smooth polished surface such as metal and the light ray bounces back, it is called the reflection of light. The incident light ray which land on the surface is reflected off from the surface. The light ray that bounces back is called the reflected ray.

Therefore, the correct option is A.

Epigenetics refers to all changes in gene expression that are not associated with the DNA (nucleotide) sequence.

Epigenetic modifications include DNA methylation, histone modifications (e.g., acetylation methylation, etc) and regulatory non-coding RNA pathways.

The variation in the DNA methylation pattern may be associated with suppression (or activation) of gene expression.

The Secret Service also investigated smugglers, individuals perpetrating land or real-estate fraud, distillers of illegal liquor, and the Ku Klux Klan. In 1894, the protective duties of the Secret Service began informally with agents providing part-time protection to President Grover Cleveland. Following the assassination of President William McKinley, Congress informally requested presidential security service. In 1902, the Secret Service assumed full time responsibility for protecting the president and his family. In 1908, this protection was also extended to the president-elect. In 1913, Congress authorized permanent protection of the president. Following the assassination of President John F.
