As the star ages it will slowly loses it's shine and helium. Sooner or later the star will finally die out due to lack of energy and it will explode and become a supernova which will become a black hole.

In familial hypercholesterolemia, individuals homozygous for the allele causing the disorder completely lack receptor while indi
a_sh-v [17]

The right answer is C.

Incomplete dominance is when hybrids of the F1 generation have an intermediate phenotype (between the two phenotypes). That is, in the case of familial hypercholesterolemia, if the subject is heterozygous it will have 50% functional receptors compared to a healthy homozygous subject.

Through which microscope were cells first observed?
poizon [28]

Compound microscope

<h3>Further explanation</h3>

In 1665, Robert Hooke used a compound microscope to observe cells. Hooke observes the cell walls of dead plants (in the form of cork) when they appear under a microscope. He named it the cell because it looked similar to a cellula or small room inhabited by monks.

Development of microscopy:

  • 1590: Hans and Zacharias Janssen, as Dutch lens grinders, mounted two lenses in a tube to produce the first compound microscope.
  • 1660: Robert Hooke published <em>Micrographia</em>, containing detailed observations of biological materials made with the best compound microscope.
  • 1676: Anton van Leeuwenhoek was the first person to observe a live cell under a microscope, i.e., the algae Spirogyra.
  • 1931: Ernst Ruska constructed the first electron microscope. With the invention of the electron microscope, many infectious agents smaller than bacteria could be seen.

Until now, we can see how important the use of microscopes, especially in microbiology, that is the study of microorganisms.

Drag the tiles to the correct boxes to complete the pairs.
kirill [66]

Answer:

Cause: Earth’s magnetosphere traps radioactive  solar wind particles in bands around Earth → Space travel through the Van Allen  belts is dangerous.

Cause: Earth is surrounded by a magnetic field → Effect: Solar wind deflects toward the poles.

Cause: Solar wind particles interact with Earth’s  upper atmosphere → Effect: An aurora is created

Explanation:

I have been able to drag the tiles to the correct boxes to complete the pairs.

When there is a trapping of radioactive solar wind particles in bands by the earth's magnetosphere, it becomes dangerous to travel in space through the Van Allen. Cosmic rays and solar particle add up to the additional hazards that it poses. A Van Allen radiation belt is known to be a zone  where energetic charged particles are found. Most of the energetic charged particles originate from the solar wind.  The solar wind  are captured by and held around a planet by that planet's magnetic field.

When the solar wind interacts with the earth's atmosphere, there is a collision of atoms of oxygen and nitrogen from the earth's atmosphere. The energy that is formed is a colorful glowing halo which is known as an aurora.

A viral hepatitis screen with positive hepatitis B surface antigen (HBsAg) should be interpreted as ________ hepatitis B
Nostrana [21]

Answer:

Acute.

Explanation:

Viral hepatitis may be defined as the virus that causes inflammation in the lung and causes swelling in the injured tissue and the lung. Five different hepatitis virus are A,B,C,D and E.

The acute hepatitis virus quality is shown by all the types of the virus strain. In the acute form, the surface antigen is similar with the virus strain. While sowing the positive screen testing, the virus that shows the similar antigenic strain can be considered as acute virus.

Thus, the answer is acute.
