When measuring the brightness of a star, what is a limitation of using apparent magnitude rather than absolute brightness?


Apparent magnitude does not use the star's color or temperature.


Apparent magnitude is only theoretical, thus its value cannot be directly measured with equipment.


Apparent magnitude does not take into account the fact that not all stars are the same distance from Earth.


Apparent magnitude is only on a comparative scale that determines how bright a star looks from a theoretical distance of 32 light-years from Earth.

Which of the following technologies involve inbreeding?
A. Selective Breeding
B. Gene Therapy
C. Cloning
D. GMO
E. All of the above

Answers

This is a tough question, So, selective breeding is like chickens and cows they are bred just to produce cows-milk and chickens-eggs. Gene therapy doesn’t even sound appetizing or good, but I think it’s like altering genes and just creating chaos. Cloning is just copying and making an exact version. GMO is genetically modified organisms, which is what they’ve been doing to vegetation by making them bigger. So inbreeding is like incest( when two people with almost the exact same genes mate and have a child) except it’s mainly done on animals. I think the closest one would be selective breeding. I’m sorry if I’m wrong I try my hardest at gathering information with only a few minutes.

Wegener's theory of continental drift? Explain your answer.

Answers

Answer:

Explanation:

It does not support Wegener's theory of continental drift. Africa and South America were the part of a same land mass at one time, which then got separated into two different land forms called North America and South America and drifted to different locations other than the one from where they originated. This occurred due to continental drift. The evidence of this phenomena can be observed in fossils that were found to be same in both land forms. This depicts that same type of organisms were living in both land forms. Hence, gives the evidence that land forms were related.

1. An unstable nucleus releases radiation in the form of a helium particle. What process is occurring!
a) Fusion
b) Fission
c) Alpha Decay
d) Beta Decay

Answers

Alpha Decay
When a nucleus is unstable because it has to many protons, it releases an alpha particle. An alpha particle consists of two protons and two neutrons, so it’s a helium nucleus. This is alpha decay.

An unstable nucleus with too many protons emits energy and an alpha particle during alpha decay. An alpha particle is actually a helium nucleus because it has two protons and two neutrons. A nuclear equation can be used to represent alpha decay. Thus, option C is correct.

What is the alpha decay releases of radiation from helium?

When an unstable nucleus changes to another element, a nuclear process called “alpha decay” produces a particle consisting of two protons and two neutrons. The helium nucleus that is being ejected is known as an alpha particle.

An alpha particle is released when a nucleus becomes unstable due to having an excessive number of protons. An alpha particle is a helium nucleus, since it has two protons and two neutrons. This is the alpha decay.

Therefore, Each of the two protons and two neutrons that make up an alpha particle is a helium nucleus that has lost its planetary electrons.
