Sheep Brain Dissection Steps

Answers

Answer 1
Sheep brains, like other sheep organs, are much smaller than human brains, but have similar feature. They can be a valuable addition to your study of anatomy.

See for yourself what the cerebrum, cerebellum, spinal cord, gray and white matter, and other parts of the brain look like with this sheep brain dissection guide! Use this for a high school lab, or just look at the labeled images to get an idea of what the brain looks like.

You’ll need a preserved sheep brain for the dissection. Set the brain down so the flatter side, with the white spinal cord at one end, rests on the dissection pan. Notice that the brain has two halves, or hemispheres. Can you tell the difference between the cerebrum and the cerebellum? Do the ridges (called gyri) and grooves (sulci) in the tissue look different? How does the surface feel?

Turn the brain over. You’ll probably be able to identify the medulla, pons, midbrain, optic chiasm, and olfactory bulbs. Find the olfactory bulb on each hemisphere. These will be slightly smoother and a different shade than the tissue around them. The olfactory bulbs control the sense of smell. The nerves to the nose are no longer connected, but you can see nubby ends where they were. The nerves to your mouth and lower body are attached to the medulla; the nerves to your eyes are connected to the optic chiasm. Using a magnifying glass, see if you can find some of the nerve stubs.

To assist in completing this question, you may reference the Animated Technique Video - Gel-Filtration Chromatography. Consider a mixture of four proteins with various molecular weights. A histone molecule weighs 15 kDa, a p53 molecule weighs 53 kDa, an actin molecule weighs 42 kDa, and an IgG molecule weighs 150 kDa. Arrange the molecules in order of their elution from a gel filtration column

Answers

Answer:

IgG molecule, p53 molecule, actin molecule, histone molecule

Explanation:

In a Gel-Filtration chromatography, the larger molecules elude faster from the gel than the small ones.

In a Gel-Filtration chromatography, there is a stationary phase and a mobile phase. The stationary phase has beads with pores. Small molecules enter the beads and descend through these beads' pores. On the other hand, large molecules do not enter the beads' pores, so they go down through the mobile phase faster than the small molecules. Since they do not have the obstacle of the pores, they descend between the beads more fluidly. As a result, the larger molecules elute first from the gel than the small molecules.

The Sun has a diameter of approximately 1,391,400 kilometers. How big would the Sun be in your scaled-down model of the solar system? Explain how you scaled the Sun’s diameter to fit into your model, and describe how its size compares to the planets.

Answers

Answer:

About 100 times more than other planets.

Explanation:

The Sun would be about 100 times bigger than the earth planet in the scaled-down model of the solar system because in the reality the size of sun is 109 times more than the earth so making a model more perfect and nearer to reality we have to maintain the diameter of the sun more than 100 times than the earth and other planets.

Hello. It is not possible to make a report of your class in the laboratory, without having attended that class. For this reason, I will show you how this report can be written. I hope it helps you.

You should start your report with an introduction. This will be a short paragraph, where you will present the laboratory where the class was held, the time and date. Then you will give a brief presentation of what was observed during that class.

In a second paragraph, you will start by explaining better, all the elements of the class, what was discussed and what equipment was used. You should also show all the activities done in the laboratory in the most detailed way possible. This paragraph can be divided into more than one paragraph, if you have a lot of information to tell.

Finally, you should end the report with a conclusion, showing what you have learned from this experience.

Answers

Answer:

means that both the necessary mRNAs must persist and there must be a low level of RNA-degrading enzymes present

Explanation:

Mature red blood cells (also known as erythrocytes) don't contain nuclei. The red blood cells that enter the bloodstream eject their nuclei in order to have more space for transporting hemoglobin, a protein whose main function is to bind molecular oxygen. Erythrocytes have a life span period of three (3) to four (4) months. During this period, the mRNA of the hemoglobin genes must remain intact in order to synthesize hemoglobin proteins (i.e., their subunits). Moreover, in mature red blood cells, the levels of the enzymes involved in the degradation of cytoplasmic mRNA (ribonucleases) must also be low to avoid bulk mRNA degradation.

A compass needle is affected by Earth's magnetic field.

A magnetic field is strongest at the poles.

Explanation:

An element or a substance that attracts other metals is called a magnet. In magnet there are two poles, these poles are as follows:-

South poleNorth pole

The correct option for the question is A.

The earth also behaves like a magnet and it has two poles just like a magnet.

When a needle is placed in water it deflects because of the magnetic effect of the earth.

What would be a good explanation for her to give to the jury?

That at least 10 different points on the two samples matched
That the DNA profile matches someone with the suspect's hair color and skin tone
That she found one point that matched on the two DNA samples
That the DNA samples showed no clear points in common

Answers

She will give the DNA fingerprinting report to the jury which will have samples of suspect and its profile matching to the evidence found at the scene of crime.


In DNA fingerprinting hair, blood, semen, or other biological samples are required for the comparison of suspect and evidence. It depends on the unique polymorphism in their DNA.
The fragments of DNA are made to run on the electrophoresis gel and the similar bands observed will confirm the matching.
The DNA fingerprinting will provide very exact evidence if the DNA samples matched.

The points at which max potential and max kinetic energy is the last second point away from the boy is max potential and the last point is the max kinetic.

What are max potential and max kinetic energy?

The product of an object's mass (m), gravitational acceleration (g), and height is its potential energy (PE) (h). Maximum kinetic energy is the amount of energy present when both the speed and the potential energy are at their highest levels.

The boy is batting the ball and the ball went to the highest point is the max potential energy, then when the ball goes into the distance is called the max kinetic energy.

Therefore, maximum kinetic and potential energy are present at the final point and the mid or in the diagram, the 4th point respectively.

A population of 6000 ants lives inside a dead log that measures 3 square meters. What is the population density of the ants?

Answers

Answer:

2000 ants per square meters.

Explanation:

The population density, D, of a population can be calculated by dividing the total number of individuals by the area covered by that population. That is;

D = N/A

Where;

D = population density

N = population of individual organism

A = area covered (m²)

According to this question, a population of 6000 ants lives inside a dead log that measures 3 square meters. Hence, N = 6000 ants, and A = 3m²

Therefore, the population density (D) = 6000/3

= 2000

The population density is 2000 ants/square meter.
