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:

"Lack of shade" means that the ponds no longer have enough coverage over them such that the sun shines strong above the river causing it to dry up. Trees are mostly huge tall and are very likely to provide shade for the river originally, and since deforestation means the mass cutting down of trees, the answer is c.

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.

The esophagus, a tube that carries food to the stomach, is constantly being scraped as food travels through it. Why does the esophagus not deteriorate through a person’s lifetime? Cells can anabolize the food prior to entering the esophagus. Cells are constantly dividing and replacing old or damaged cells. Cells promote a fluid to build up along the esophagus to reduce friction. Cells build a type of protein called enzymes that act as an armor.

Answers

Cells are constantly dividing and replacing old or damaged cells.

The esophagus does not deteriorate throughout a persons life due to cellular reproduction. When the cells are scraped off by the food, mitosis, or cellular division occurs resulting in two daughter cells from one which will eventually replace the missing cells.

Many farmers and gardeners compost their plant and animal waste. The living material naturally decays in compost bins, forming a dirt-like substance that’s rich in nutrients. The next season, farmers use this substance as a natural fertilizer for their crops. A biology student has grown tomato plants for several years. Until now, he used an artificial fertilizer formulated for tomato plants. This fertilizer caused his plants to grow faster and taller than they grew in unfertilized soil. The student wants to know whether using natural compost will cause his tomato plants to grow faster and taller than his artificial fertilizer. How does the design of your experiment control for outside factors that may affect the results?

Answers

yes the fertile soil will grow faster and taller

In order for a dead organisms remains to become fossilized certain conditions must be met. summarize three of these conditions.

Answers

The organism generally must have hard parts such as shell, bone, teeth, or wood tissue; the remains must escape destruction after death; and the remains must be buried rapidly to stop decomposition. This does make the fossil record biased because animals with soft bodies are less likely to form fossils. It also means that particular environments will not help fossils form because the remains must be buried rapidly and escape the detection of scavengers.
4. Describe three different methods of fossilization.
Organisms can be buried and preserved in substances such as frozen soil, volcanic ash, sediment, ice, oil, and amber. This process preserves even the soft parts. Hard parts such as shells, teeth, bones, and wood can also be more easily preserved because they resist weathering. Hard parts can also become altered due to carbonization (leaves only a thin film of carbonaceous material), petrifaction (gets replaced by minerals in water turning it to stone), and replacement (hard parts dissolve and get replaced by calcite, silica, dolomite, and iron compounds)

The vast majority of deceased organisms vanish without a trace, so fossilization is a rare process.

What are the conditions that favor fossilization:

Hardbody parts (bones, teeth, shells) will fossilize; soft body parts will not but may leave traces (e.g. imprints)

Remains preserved (protection against scavenging, erosion, and environmental damage)

There is a lot of pressure to get the remains mineralized (i.e. turn hard body parts into fossilized rocks)

Anoxic (low oxygen) conditions are used to protect against oxygen damage and to prevent saprotroph decomposition.

Thus, we can conclude that hardbody parts remain preserved, and high pressure and anoxic conditions are required during fossilized.

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.
