Answer:

A band - light central region of sarcomere.

Explanation:

Sarcomere is the basic structural unit of the skeletal muscles. These sarcomere shows striations ( light and dark bands) when veiw under the microscope.

A band or anisotropic band is the dark region of sarcomere. A band consists of both thick and thin filaments of actin and myosin proteins. The A band has the ability to refract light and appears dark.

Thus, the correct answer is option (D).

A few things:

<span>1. it secretes insulin, which the body uses to utilize glucose (in the kind of diabetes most people have, their tissues have become resistant to insulin requiring more and more of it to be produced by the pancreas) </span>
<span>
2. it produces things called pancreatic enzymes which help us digest foods (especially fatty ones) </span>

3. the other things it secretes are somatostatin which regulates growth hormone, and glucagon which is related to insulin in that it also helps regulate the body's sugar (kind of an anti-insulin) </span>

2. As a result of your initial efforts you were able to detect the presence of protein K using IgG. However, when your lab mate
Viefleur [7K]

Answer:

Protein K is a protein that can available in the human cell nucleus that binds to pre-messenger RNA as a part of heterogenous ribonucleoprotein. IgG is one of the five isotypes of immunoglobulin or antibodies.it is the most common antibodies in the blood circulation and makes the 75% of total antibody.

When you heat solution, generally protein k activity increase with an increase in the heat but up to an extent or point called optimum temp. The optimal temperature for activity ranges between 50-65°c. When an increase in temperature help with protein unfolding easing the ability for protein k to break down those proteins.

What is the difference between a photoheterotroph and chemoheterotroph, and what are examples of these?
RoseWind [281]
<span>When classifying organisms like this, you are looking for two main descriptors of their lifestyle: how they get their energy and how they get their carbon. A phototroph is an organism that acquires its energy through harvesting photons. A chemotroph harvests energy from chemical bonds.

The term heterotroph is used to describe organisms that acquire carbon from organic substances (namely from other organisms). An autotroph is an organism that has the ability to fix atmospheric carbon CO2 into an organic form.

When you combine these terms, you get a word that describes how an organism harvests energy and carbon. So, a chemoheterotroph is an organism that acquires energy from chemical bonds, and uses acquires organic carbon from an external source (usually, in this case, the energy and carbon come from the same source, e.g., glucose). A photoheterotroph is an organism that gains energy from photons but gains carbon from an external organic source.

Most bacteria, fungi, and animals can easily be described as a chemoheterotroph. A specific bacteria would be Pseudomonas aeruginosa.

Photoheterotrophs would only be found in the prokaryote domains. An example would be Heliobacter. Just to note, there are very few genera of photoheterotrophs. Remember, they gain most of their energy from light (photons), and their carbon from an external organic source (i.e., they do not fix carbon).

</span><span>Basically, photoheterotrophs get energy from light and chemoheterotrophs get energy from breaking chemical bonds.
