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.

What is the mechanism by which the secretion of a hormone is followed by travel to a distant target cell

Answers

Answer:

induction or repression of enzymes

Explanation:

Hormones are chemical messengers which are secreted by endocrine glands and regulate the rate of existing activities, usually through the induction or repression of enzymes within distant target cells via the endocrine system. They travel in the bloodstream, having slower, but longer lasting effect and are effective in small quantities.

hope it helps

The mechanism by which the secretion of a hormone is followed by travel to a distant target cell is primarily through the bloodstream. Once in the bloodstream, hormones are carried throughout the body, allowing them to reach their target cells or tissues.

Hormones are usually released in small amounts but have potent effects on target cells. The binding of a hormone to its specific receptor triggers signaling pathways within the target cell, leading to changes in cellular function or gene expression.

The travel of hormones through the bloodstream ensures their widespread distribution and enables them to reach distant target cells located in different organs or tissues.

This mechanism allows hormones to exert their regulatory effects on various physiological processes, including growth and development, metabolism, reproduction, and homeostasis.

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.

A student named Janine says that the measure of side b is 64 ft. Please state whether this is correct or incorrect. If this is incorrect, state the length of b. Explain your answer in complete sentences. Use vocabulary such as Pythagorean Theorem, side, hypotenuse, square root etc.

Answers

The measure of side b as 64 ft is incorrect. The accurate measure would be 8 ft.

According to the Pythagorean theorem, the square of the hypotenuse of a right-angle triangle is the sum of squares of the opposite and the adjacent sides. Mathematically:

[tex]hypotenuse^2 = opposite^2 + adjacent^2[/tex]

In this case, the hypotenuse = 10 ft, the opposite = 6 ft and the adjacent = b

Hence,

b^2 = 10^2 - 6^2

       = 100 - 36

          = 64

b = √64

     = 8 ft

Thus, the side b is 8 ft and not 64 ft.

Causal attribution theories generally try to explain how we:

1) are influenced by others

2) predict how others will behave based on their attitudes

3) change our attitudes toward other people

4) determine the causes of others' behavior

5) relate to and interact with other people

Answers

Causal attribution theories generally try to explain how we determine the causes of the others' behavior based on personal or situational attributions.

This theory was developed by Horald Kelly in 1967, and explains how people attribute the behavior of others according to dispositional (internal) and situational (external) factors.

Dispositional factors are those based on internal characteristics, such as effort and skill. Situational factors, on the other hand, are environmental and external to the individual, such as luck and task difficulty.

Therefore, according to theory we are more likely to attribute the cause of the behavior of others to factors that most coincide with the action.
