Answer 1

Answer:

Focal length of the lens increases hence the size of the lens increases.

3)B

4) B

Explanation:

3)Focal length of the lens increases hence the size of the lens increases.

Pupil of the eye decreases in size so as to decrease the amount of sunlight entering the eye when the person looks at the sky. As the size of the pupil was increased for increase the intake of the light while reading a book in the shade

4) Im not really sure, but i am pretty sure it's B. Don't take my word ;D

Answers

Answer:

1. cell proliferation

2. multipotent

Explanation:

Microorganisms of a family of fungi, called the Lepiotaceae, live with leaf-cutter ants. The ants collect fresh leaves to grow the
fungus, and then they feed the fungus to their larvae. Another type of microorganism, a fungus of the Ophiocordyceps family, also
has a relationship with a type of ant. The spores of the fungus attaches to carpenter ants in order to complete its life cycle. The
spores spread into the ant's body and causes behavioral changes in the ant, eventually causing the ant's death.
What does this information demonstrate?

Answers

Answer:

Between the Lepiotaceael and the eaf-cutter ants, there is what we call mutualism. They both depend on each other buh no harm is done.

But between Ophiocordyceps family and the carpenter ants, it is called parasitic relationship. The Ophiocordyceps harms the carpenter ants.

are mutations good or bad

Answers

Answer: Mutations can be good or bad.  

Explanation:

Both. Mutations can be good because it can help the species evolve to make survival easier. But they can also be bad because they can cause the opposite to happen.

A- A.

Answers

Answer:

See below

Explanation:

This new model perhaps better explains the elements required in order for photosynthesis to take place. Sunlight, water, carbon dioxide are essential for the plant so it can produce it own food. Someone who is not previously familiar with the process of photosynthesis needs to start from these basics and then further build on this knowledge.

Answer:

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. This model also shows the number of each molecule created, which the original model doesn’t do.

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.
