What do you think happened to the light from the lightbulb as it passed through the spectroscopy telescope?

Answers

Answer:

through a tiny hole or slit in a metal plate to isolate light from a single area or object.

The light from the lightbulb, as it passed through the spectroscopy telescope, underwent a process of dispersion. This resulted in the separation of the light into its component colors, forming a spectrum.

When light from a source like a lightbulb passes through a spectroscopy telescope, it encounters a prism or a diffraction grating. These optical components disperse the light based on its wavelengths. As a result of dispersion, different colors that make up the light are bent by varying amounts, causing them to spread out.

This separation of colors forms a spectrum, known as a continuous spectrum. This spectrum acts as a fingerprint, revealing the unique composition of the source's light, enabling scientists to analyze the elements or molecules present in the source material.

Which kind of force do you exert on an object when you pull it toward you?
A applied force

B.
attractive force

c. drag force

D
normal force

Answers

Answer:

I would say B is the answer.

Explanation:

An applied force is a force that is applied to an object by a person or another object. Example: pushing a box to the other side of a room.

A normal force is a force that surfaces exert to prevent solid objects from passing through each other. Example: resting a book upon a table.

Drag is a force acting opposite to the relative motion of any object moving with respect to a surrounding fluid. This doesn't really match the force we use.

However, an attractive force is a force by which one object attracts another. Example: two magnets pulling/colliding together. This is a good example of a force we exert on objects when it is pulled toward us.

I took the test and got it correct

Type of mutation reverses the direction of parts of a chromosome is inversion. The correct answer is option C.

What is the basic structure of chromosome ?

The chromosomes are thread like structures present in the nucleus and the  these chromosomes carry the genetic information in them from one generation to another.

Inversion inverts the structure of chromsome and it basically turns the chromsomes inverted.

Inversion is the process where one arm of the chromosome gets detached from the basic structure and it gets attached in the inverted direction.

This  creates multiple copies of DNA turning it into genetic material and one of the X linked recessive disorders is haemophilia in which same type of mutation caused by the chromosome at the 8th position takes place.

Therefore, Mutation that reverses the directions of the part of the chromosome.

IF a man with blood type A, one one of whose parents had blood type O, marries a woman with blood type AB, what are the putative genotypes of the offspring?

Answers

Answer:

The 1st child will surely have AA,The 2nd might have AB/OB and the last one will surely have OB

Explanation:

I studied at school like 2 yrs ago

I am sure

Answer:

If the man has blood type A one of whose parents had blood type O then he must be having the genotype IAi and the woman with blood group AB would have genotype IAIB. So if they produce offspring than the putative genotype of the offspring would be IAIA, IAi, IAIB, and IBi.

Explanation:

                   IA        i

             IA   IAIA   IAi

             IB   IAIB    IBi

Therefore out of four offspring, two offspring would be having A blood group, one offspring would have AB blood group and one offspring would have B blood group.
