Answer: The amplitude of a wave tells us about the intensity or brightness of the light relative to other light waves of the same wavelength. Both Wave 1 and Wave 2 have the same wavelength but different amplitudes. The wavelength of light is an important property for it is this that determines the nature of the light. brainliest

Which of the following is associated with extracellular digestion caused by release of the lysosomes enzymes into the environmen

Rudik [331]

Answer: Rheumatoid arthritis

Explanation:

Rheumatoid arthritis is a disease which is a autoimmune disease which is usually associated with the pain and inflammation in the joints. This is the condition in which the person is not able to walk or sit for a longer period of time as it is painful.

The lysosomes is an enzyme that is found in the saliva and tears of human beings which helps in the degradation of the cell wall.

In case of autoimmune diseases the antibody present in the body destroys the cells of the body considering it as self antigen. Its concentration is found high in the people suffering from this autoimmune disorder.

A student does an experiment for a science fair to study whether temperature affects the timing of a cricketâ€™s chirps. The stu

nexus9112 [7]

The frequency of chirps increases as the temperature increases. The correct option is B. The chirps occur closer together as the temperature increases.

-------------------------------

<h2>Available data:</h2>

<h3>Data recorded by the student </h3>

Day Temperature Average time between chirps (sec)

1 21 2. 5

2 22 2. 6

3 23 2. 2

4 24 2. 3

5 25 2. 0

6 26 1. 8

7 27 1. 9

8 28 1. 8

9 29 1. 4

10 30 1. 2

11 31 1. 5

12 32 1. 1

In this experiment the student recorded the time in seconds between chirps.

We can see that as the temperature increases, in general, the time between chirps decreases.

At 21ºC the time between chirps is 2.5 seconds

At 26ºC the time between chirps is 1.8 seconds

At 32ºC the time between chirps is 1.1 seconds

According to this information, if the average time between chirps decreases with the temperature increase, we can assume that the frequency of chirps increases as the temperature gets higher.

<h3>Options,</h3>

A) The higher the temperature, the fewer chirps there will be in 10 seconds.

Wrong. The number of chirps in 10 seconds will depend, not only on the frequency but also on how long the chirps last. Since the student did not record the time of chirps, we can not make this conclusion.

B) The chirps occur closer together as the temperature increases.

True. The chirps increase in frequency as the temperature increases, so they occur closer together.

C) The chirps become farther apart as the temperature increases.

Wrong. We can see how the time between chirps decreases as temperature increases, meaning that they are closer not farther.

D) There is no relationship between temperature and the time between chirps.

Wrong. If we make a graph we will see the tendency and the relationship between chirps and temperature.

Graphs usually explain the relationship between variables. In this example, the relationship would be inverse.

Anna [14]

Petri dishes should always be stored inverted.

In biology, petri dishes are frequently used to produce microorganisms like bacteria, yeast, and mold. The organisms that grow on solid or semisolid surfaces are best suited for it. To reduce the chance of contamination from airborne spore particles landing on them and to avoid the buildup of water condensation that could disrupt or impair a culture, they are often covered and stored inverted.

Aside from that, incubating the media in the normal position could result in the media drying out, which would interfere with the ideal conditions for microbial growth and increase microbial count mistakes. Since the labels are put underneath the plates rather than on the lids, placing plates upside down also makes them easier to handle and recognize.
