In a closed container, what happens to the pressure and motion of molecules when you add more molecules to the system? Please be sure to explain why this happens.

Answers

When you add more molecules, the pressure increases and the notion of molecules slow down. This happens because it’s like filling a box and inside the box there is less room to move around as you fill it.

Answer: would the pressure increase?

Explanation:

Because more molecules are being put into the container.


Which pairs of angles in the figure below are vertical angles?

Answers

Answer: C

Explanation: In the diagram shown, <ISN and <TSW

are called vertical angles.

Vertical angles, such as angles <ISN and <TSW can be

defined as angles the share a common vertex, in this case x,

and whose sides form opposite rays.

Answer:

C. Angles ISN and TSW

Explanation:

The definition of vertical angles is "each of the pairs of opposite angles made by two intersecting lines."

In the image lines WN and TI intersect at vertex S to create opposite (vertical) angles ISN and TSW.

Describe wavelength, amplitude, and frequency in relationship to vision and hearing

Answers

Explanation:

Visual and auditory stimuli both occur in the form of waves. Although the two stimuli are very different in terms of composition, wave forms share similar characteristics that are especially important to our visual and auditory perceptions. Waveforms of different types surround us at all times, however we only have receptors which are sensitive to specific types of wavelengths. In this section, we describe the physical properties of the waves as well as the perceptual experiences associated with them.

AMPLITUDE AND WAVELENGTH

Two physical characteristics of a wave are amplitude and wavelength (figure below). The amplitude of a wave is the height of a wave as measured from the highest point on the wave (peak or crest) to the lowest point on the wave (trough). Wavelength refers to the length of a wave from one peak to the next.

 

The amplitude or height of a wave is measured from the peak to the trough. The wavelength is measured from peak to peak.

 

   Wavelength is directly related to the frequency of a given wave form. Frequency refers to the number of waves that pass a given point in a given time period and is often expressed in terms of hertz (Hz), or cycles per second. Longer wavelengths will have lower frequencies, and shorter wavelengths will have higher frequencies 

Wavelength and frequency are inversely related so that longer waves have lower frequencies, and shorter waves have higher frequencies. In the visual system, a light wave's wavelength is generally associated with color, and its amplitude is associated with brightness.

Explanation:

Hope it helps I found it on brainly

Answer:

They break down dead organisms and recycle nutrients.  

Explanation:

Saprophytes are the living organisms that feed upon dead organisms such as plants, animals, and their decaying products. They contribute to the food web because they help in clearing up the biological waste from the environment and make the resources after degradation available to the plants as soil nutrients. Therefore, helps in nutrient recycling in an ecosystem.

Which directional terms best describe the location of the sternum in relation to the vertebral column? in the axial region of the body, inferior to the vertebral column in the appendicular region of the body, anterior to the vertebral column in the appendicular region of the body, superior to the vertebral column in the axial region of the body, anterior to the vertebral column

Answers

Answer:

Anterior

Explanation:

In anatomical terminology there are several words to indicate the position or part of the body that is being mentioned in a more specific and precise way, a group of these terms are called directional terms, they focus on the position of a specific part, one of the words in this group is "anterior" it basically means "in front of". The sternum is in front of the vertebral column.

The sternum, also known as the breastbone, is located in the middle of the thoracic (chest) region of the axial body. The correct answer is: In the axial region of the body, anterior to the vertebral column.

The axial region refers to the central part of the body, which includes the head, neck, and trunk. In this case, we are specifically referring to the trunk region where the sternum is located. Anterior means towards the front or the ventral side of the body. In anatomical terms, the front side of the body is considered the anterior side.

Sternum is positioned anteriorly, meaning it is in front of or facing the front of the body. In relation to the vertebral column, which is part of the axial skeleton and runs along the posterior (back) side of the body, the sternum is anterior.

Therefore, the correct answer is: In the axial region of the body, anterior to the vertebral column.

What are amino acids?

Amino acids are the organic compounds that is mixture of one amino and one carboxylate group.

There are 20 sets of amino acids that are used as building blocks of protein.

The sequence of the amino acid causes the protein to fold into a shape which is biologically active. Genes encode the amino acid sequence of protein.

Someone who is not previously familiar with the process of photosynthesis needs to start from these basics and then further build on this knowledge.

This model shows all the major molecules involved in the Calvin cycle and how they change at each stage of the process. This added detail would clarify that the Calvin cycle is a series of complex steps. The student’s original model didn’t show this breakdown at all, and it shows only the final products.
