Answer:

The perecentage of guanine is 30%

Explanation:

the DNA from any cell of all organisms should have a 1:1 ratio (base Pair Rule) of purine bases [for the DNA cytosine, thymine and for the RNA uracil] and pyrimidine bases [guanine and adenine for RNA and DNA]. The amount of guanine should be equaled to cytosine and the amount of adenine should be equaled to thymine. You can follow this rule in both strands of the DNA.

Answer:

Option 4, an autoimmune disorder, is the correct answer.

Explanation:

An autoimmune disorder can be described as a disorder in which the immune cells of a body attack the own cells of a body.

Lupus can be described as an autoimmune disease which is long termed. In this disorder, a person's immune system attacks its own healthy cells. The immune system is unable to differentiate between the pathogenic cells and the healthy cells of the body. As a result, tissue damage is caused.

Which is the least number of seismograph stations needed to locate the epicenter of a earthquake

Hunter-Best [27]

At least three seismograph stations are needed to locate the epicenter of a earthquake.

Further Explanation:

An earthquake occurs when two region of the earth slip past each other. Fault plane is the area where the slip occurs. Hypocenter is the region below the earth’s surface where earthquake starts while the epicenter is the region above it.

The earth consists of four major layer:

1. Inner core

2. Outer core

3. Mantle

4. Crust

Seismographs is an instrument used to record the earthquake. The recording done by this instrument is called as the seismograms.

The seismograph comprises of:

1. A base: is fixed tightly in the ground

2. Heavy weight: hangs freely

When the earthquake occurs, the ground shakes and in turn the seismograph also shakes while the hanging weight does not shakes. During the earthquake, the difference in the location between the shaking piece and the motionless piece is recorded. Magnitude of the earthquake is recorded as one for each earthquake. The magnitude of earthquake is measured by the Richter scale but is more commonly measured through moment magnitude scale.

Which of the following is a eukaryotic cell? Select all that apply

zhuklara [117]

Hi there!

The most important thing to note here is that eukaryotic cells have nuclei. This is the circular blob-like organelle which encases the DNA. Some other differences eukaryotic cells have over prokaryotic cells include more complicated organelles which are membrane bound.

If we look at these images, what we are looking for is a nuclei, as this will appear most evident. When we look at A and B, we can see a circular organelle that is extremely prominent. However, with C and D, that does not appear. C specifically, the nucleic code is exposed and not membrane bound, meaning it is not prokaryotic. D does not appear to contain a nucleus or any genetic material.

Thus, your answer is A and B.

Hope this helps!
