Answer:

false

Answer:

B

Explanation:

Natural selection increases the frequency of adaptive mutations in a population over time.

Answer:

Part A:

— Chlorophyll absorbs different wavelengths than chlorophyll does. 

— Chlorophyll does not absorb wavelengths that are green and yellow, which is indicated by a very low degree of the light absorption.

Part B: 

Photosynthetic Organisms are organisms capable of photosynthesis. Photosynthesis is greenery and other organisms using the energy from sunlight to synthesize foods from carbon dioxide and water. Leaving allophycocyanin to be the protein these plants and other organisms receive from the light. So for the process, in order for the plants to live they must be able to go through photosynthesis giving the plants the energy and proteins they need to produce food and to release oxygen into the environment.

Answer:

The visible spectrum is the only part of the electromagnetic spectrum that can be seen by the human eye. It includes electromagnetic radiation whose wavelength is between about 400 nm and 700 nm.

Visible light from the sun appears white, but it’s actually made up of multiple wavelengths (colors) of light. You can see these different colors when white light passes through a prism: because the different wavelengths of light are bent at different angles as they pass through the prism, they spread out and form what we see as a rainbow. Red light has the longest wavelength and the least energy, while violet light has the shortest wavelength and the most energy.

Photosynthesis, the sun’s energy is converted to chemical energy by photosynthetic organisms. However, the various wavelengths in sunlight are not all used equally in photosynthesis. Instead, photosynthetic organisms contain light-absorbing molecules called pigments that absorb only specific wavelengths of visible light, while reflecting others.

The set of wavelengths absorbed by a pigment is its absorption spectrum. The set of wavelengths that a pigment doesn't absorb are reflected, and the reflected light is what we see as color. For instance, plants appear green to us because they contain many chlorophyll a and b molecules, which reflect green light.

Although both chlorophyll a and chlorophyll b absorb light, chlorophyll a plays a unique and crucial role in converting light energy to chemical energy (as you can explore in the light-dependent reactions article).

All photosynthetic plants, algae, and cyanobacteria contain chlorophyll a, whereas only plants and green algae contain chlorophyll b, along with a few types of cyanobacteria Because of the central role of chlorophyll a in photosynthesis, all pigments used in addition to chlorophyll a are known as accessory pigments—including other chlorophylls, as well as other classes of pigments like the carotenoids. The use of accessory pigments allows a broader range of wavelengths to be absorbed, and thus, more energy to be captured from sunlight.

Answer:

The main reason for the decrease in trillium is the large number of deer in the forest that are eating the trillium. The author cites a research study performed by scientists as evidence to support her claim. In this study, researchers planted two fields, each containing garlic mustard and trillium. One was left open to deer, and the other was fenced off. Scientists kept track of the fields for several years. They found that trillium was able to regain much of its original space in the protected field. In the unprotected field, there was still more garlic mustard because the deer ate the trillium. The author also states that similar research studies have been conducted in many forests across the United States, and they all reveal similar results.

Answer:

[tex]\dfrac{dy}{dx}=\dfrac{4}{25}[/tex]

Explanation:

The given expression is :

[tex]y=\dfrac{(x-1)}{(x+3)}[/tex]

We need to find dy/dx at x = 2

[tex]\dfrac{dy}{dx}=\dfrac{d}{dx}(\dfrac{x-1}{x+3})\\\\=\dfrac{(x+3)\dfrac{d}{dx}(x-1)-(x-1)\dfrac{d}{dx}(x+3)}{(x+3)^2}\\\\=\dfrac{x+3-(x-1)}{(x+3)^2}\\\\=\dfrac{x+3-x+1}{(x+3)^2}\\\\\dfrac{dy}{dx}=\dfrac{4}{(x+3)^2}[/tex]

Put x = 2 in above expression

[tex]\dfrac{dy}{dx}|x=2=\dfrac{4}{(2+3)^2}\\\\=\dfrac{4}{25}[/tex]

Hence, the value at dy/dx is [tex]\dfrac{4}{25}[/tex]

Answer:

50% or 1/2

Explanation:

The probability of their 6th child being a girl would be 50% or 1/2.

During meiosis, the female produces X eggs while the male produces X and Y sperms. A random fusion of gametes then occurs during fertilization.

                             XX    x    XY

       XX (female)   XY (male)   XX (female)   XY (male)

XX - 1/2 or 50%

XY - 1/2 or 50%

Hence, the probability of producing a girl is 1/2 or 50% irrespective of the number of kids a couple might have produced already.
