Answer:

The thymus plays an important role in deletion of potentially autoreactive T cells. However, the presence of islet-specific T cells in the circulation of type 1 diabetes patients and healthy subjects indicates that the thymus is not capable of efficiently deleting all autoreactive T cells (Mathis and Benoist 2009).

How to calculate standard cell potential of a fuel cell.

laiz [17]

Answer:

The overall cell potential can be calculated by using the equation E0cell=E0red−E0oxid. Step 2: Solve. Before adding the two reactions together, the number of electrons lost in the oxidation must equal the number of electrons gained in the reduction. The silver half-cell reaction must be multiplied by two.

Testosterone is an example of a chemical signal that affects the very cells that synthesize it, the neighboring cells in the tes

saw5 [17]

Answer: Autocrine signal, paracrine signal and endocrine signal.

Explanation:

Testosterone is an example of hormone which shows its effect on different locations of the cells.

The autocrine signal can be defined as the siganals which shows its effect on the cell from where it is being produced. This means a cell targets itself.

Then comes the paracrine signals in which signals acts locally on the cells nearby it. The cells close together to the cells producing chemical signals is being affected.

The endocrine signals can be defined as the effect of the hormone on the distant cells. The signals is produced by the cells somewhere else but is carried through the bloodstream to the distant cells.

All of the three effects is being shown by testosterone autocrine, endocrine and paracrine.

Examine this image and choose the most accurate statement base on relative dating.

Vlada [557]

Hello!

One of the most basic examples of relative dating, specifically in this case, would be the law of superposition. This simply states that out of many layers of rock, the oldest would be at the bottom and the youngest on top, so therefore the age of the fossils inside the rock would also increase when going down the layers. Therefore, we see that layer a is the oldest, and layer g is the youngest.

This disproves the first answer choice - the fossils in layer g are the youngest, not the oldest. Now, when comparing Layer F and D, we see that the rock layer F is above layer D. This means that layer F is younger than layer D (and same for the fossils in those respective layers). The third choice is incorrect as layer A would be older than F as it is beneath layer F.

Therefore, this means your second choice, or the fossils in layer F are newer than the fossils in layer D, is correct.

Hope this helps!
