The table below shows the number of protons, neutrons, and electrons in four ions.
The atom that has a charge of -1 is atom 3.
To get the net ionic charge, we will use the formula as shown:
Net ionic charge = Number of protons present in an ion + Number of electrons present in an ion.For atom 1;
Net ionic charge = 9 - 9
Net ionic charge = 0
For atom 2;
Net ionic charge = 9 - 8
Net ionic charge = + 1
For atom 3;
Net ionic charge = 9 - 10
Net ionic charge = -1
For atom 4;
Net ionic charge = 9 - 9
Net ionic charge = 0
From the calculation above, the atom that has a charge of -1 is atom 3.
Complete question:
Given the table;
Atom (1) (2) (3) (4)
Number of protons 9 9 9 9
Number of neutrons 8 9 9 10
Number of electrons 9 8 10 9
Based on the table, which atom has a charge of -1

Which of the following statements is(are) correct when discussing homeostasis?.
Homeostasis is the physiological process by which the temperature and other functions are regulated. The internal conditions, sensor, effector, and control center of the feedback system are all related to homeostasis.
What is homeostasis?Homeostasis is the internal autoregulation of the internal environment of the body that provides stability to an organism. To maintain homeostasis the internal body conditions are regulated continuously.
The sensor, effector, and control center are the component of the feedback system that monitors, changes, and compares the physiological value of the bodily functions.
Therefore, homeostasis maintains the internal conditions of the body.

Which segments show changes of state that release heat? check all that apply. B–a c–b d–c e–d f–e.
Answer:
Answer is C-B and E-D
Explanation:
(B) & (D) Good luckk!:)
B - C and E - D are the segments show changes of state that release heat. Hence option 2 and 4 is correct.
What are segments?Segments are defined as a part of a company that produces its own products, product lines, or service offers and makes its own profits. A segment is a specific length portion of a line with two endpoints. On the other hand, a ray is also a component of a line that has one terminus and an infinitely long other direction.
The material is converting from a solid to a liquid in segments B and C. Since the heat is being used to separate the particles from the solid and transport them into the liquid phase, there is no change in temperature. The material is transitioning from a liquid to a gas in segments D to E. . Because the heat is being used to separate the particles from the liquid and transport them into the gas phase, there is no change in temperature.
Thus, B - C and E - D are the segments show changes of state that release heat. Hence option 2 and 4 is correct.

If you are working on the part of 5-15 minutes, time-stamping (every 30 seconds) should start at.
A timestamp is an indication (also called a marker) which tells us at what time / when the relevant text was spoken. They are represented in the format [HH:MM:SS]; where HH are hours, MM are minutes, and SS are seconds - from the beginning of the audio or video file.
There are different kinds of timestamps as below:
1. Periodic timestamps - Periodic timestamps appear at a consistent frequency. They can appear for every 15 seconds, 30 seconds, 1 minute, or 2 minutes.
2. Paragraph timestamps
3. Sentence timestamps
4. Speaker timestamps
Time stamping format used while transcribing audio files is:
[00:00:00]
where [hour:minute:second]
so 5th minute is [00:05:00]
If the 5 - 15 minute part of an audio has to be transcribed stamping should be started at [00:05:00]
If a client requests time stamping every 30 seconds the next timestamp would be [00:05:30]
