5) The following picture is of a single organism that has been Gram stained and is viewed under oil immersion on the compound light microscope. What is the reason for a single organism appearing like this after being Gram stained

Answers

Hi. You have not submitted any images about the microorganism the question refers to. This makes it impossible for me to answer your question. However, I will try to help you as best I can.

Gram stain is a test done to find out whether the bacteria are gram negative or gram positive. In this test, the bacteria are submitted to a certain type of dye and then are observed under a microscope. If the bacteria is gram positive, it will be purple in color. If the bacteria is gram negative, it will be red in color.

This is because after they are subjected to the violet dye, both types of bacteria absorb the color of the dye. However, before being observed under the microscope, the bacteria are washed with alcohol. Alcohol removes the dye from the gram negative bacteria, leaving them reddish. On the other hand, in gram positive bacteria, alcohol dehydrates the cell wall, compressing the pores and making the cell wall impermeable, preventing the dye from being released and, therefore, leaving the bacteria with a purple color.

how to find the formula for the nth term​

Answers

“The nth term of the following types of sequences can be found out using the following Formulas:

1.Arithmetic Progression(AP) : here, the consecutive terms differ by a common difference (d).

tn= a+(n-1)d

Where,

a= is the first term of the sequence,

n= nth term

d= common difference

2. Geometric Progression(GP):

Here, the consequtive terms differ by a common ratio (r).

Tn= ar^(n-1)

where,

a = first term

r = common ratio

tn= nth term

3.Harmonic Progression (H.P):

It is the reciprocal of AP.

To find nth term of a HP, first convert it into AP and then apply the tn formula for the sequence and take the reciprocal of the obtained tn again.

Super saturated solutions are used to make rock candy. Please describe how the crystals are formed, be sure to use the terms Solute and Solvent.

Answers

Answer:

Once the solution cools, it now has more solute than it normally could have, and this is called a supersaturated solution. Once a solution becomes supersaturated, it wants to crystallize the excess solute. The solute will form crystals on any surface. In our case the surface is a string, and we are using a lifesaver candy as our “seed.”

Explanation:

Rock candy is a type of candy made by growing sugar crystals on a string or stick.

Why are Super saturated solutions used?

Super saturated solutions are often used to make rock candy because they contain more solute (sugar) than the solvent (water) can normally dissolve at a given temperature.

The first step in making rock candy is to heat water in a saucepan and add sugar to it. The sugar dissolves and forms a solution as the water heats up. After that, the solution is heated until it is completely saturated.

This occurs because the super saturated solution is unstable, and the excess solute (sugar) in the solution wants to escape and form crystals.

As time passes, more sugar dissolves from the solution and adheres to the crystals on the string or stick, causing them to grow larger.

The process is repeated until the crystals reach the desired size or until all of the excess solute has been removed from the solution.

Thus, preparing a super saturated solution of sugar and water, then dipping a string or stick into the solution and allowing the excess solute to come out of the solution and form crystals on the string or stick, is the process of making rock candy.

After a skeletal muscle fiber is treated with a membrane permeable drug that speeds up the action of the SR Ca 2-ATPase, how would contraction differ after multiple and frequent action potentials

Answers

Answer:

the twitch would be shorter

Explanation:

In muscle cells, the calcium (Ca2+) pump ATPase membrane transport proteins maintain a low cytosolic Ca2+ concentration in order to promote muscle contraction. Muscle relaxation occurs when the sarcoplasmic reticulum reabsorbs Ca2+ through the Ca2+-ATPase protein, thereby reducing intramuscular Ca2+ levels. In muscle contraction, intracellular Ca2+ levels are raised due to the release of Ca2+ from the sarcoplasmic reticulum (SR) via Ca2+-release channels. In consequence, it is expected that a specific drug that speeds up the action of (Ca2+) pump ATPase protein should shorten the contraction-relaxation cycle by increasing the velocity of muscle relaxation.

Explanation:

During exercise, epinephrine and norepinephrine are released from the adrenal medulla. Epinephrine and norepinephrine have the same effect on plasma glucose levels as glucagon. Explain how epinephrine and norepinephrine affect plasma glucose and why this is important during exercise.

Answers

Answer and explanation:

Epinephrine and norepinephrine are two hormones that are released from the adrenal medulla when the body is under stress (like during exercise, for example) as a part of the sympathetic response.

These hormones have many functions and they all work together to prepare the individual for a fight or flight response - like increasing heart rate and producing bronchodilatation. One of these functions is the rise of glucose levels in blood which is important for this substance to reach several tissues, like the skeletal muscle. The skeletal muscle will make use of this glucose to produce ATP and generate the required energy for muscle contraction through a process called glycolysis, which is key for the fight or flight response mentioned above.

When we exercise, glucose levels rise thanks to these hormones so the skeletal muscle can have enough energy to contract and move as we want. If the exercise is too intense or prolongued, glucose levels will drop and other fuels will be needed to sustain this activity, like stored glycogen and fat.

Explain how fossils, glaciers and magnetic pole wandering provide evidence that supports the theory of
plate tectonics.

Answers

Some fossils from the same species are found in different continents, across sea, these species could not swim so big distances, so it suggests that once the continents were joint and species could walk from America to Africa and other continents.

Grooves and rock deposits left by ancient glaciers are found today on different continents very close to the equator, it suggests that the glaciers either formed in the middle of the ocean and/or covered most of the Earth. Today glaciers only form on land and nearer the poles, it can be suggested that glaciers were centered over the southern land mass close to the South Pole and the continents moved to their present positions afterwards.

Polar wandering is the movement of the magnetic poles over Earth’s surface through geologic time. It suggests that plates move.

The Gondwana continents  glaciation could only have occurred if the continents were joined together since the centres of the glaciers would have been in the ocean if they were not. Also, the continents, such as South America and Africa are similar with jigsaw puzzle.

What plate tectonics theory?

The plate tectonics theory states that the earth is solid outer crust, the lithosphere, is segregated into plates which further move over the asthenosphere, the melted upper portion of the mantle. Oceanic and continental plates come and joined together, spread apart, and interact at boundaries all over the planet.

Similar fossil plant and animals are segregated by oceans leading to the assumption that they must have lived in adjacent regions when they were alive. Finally, similar rock sequences and mountain ranges could be connected across oceans.
