Biology

Aloiza [94]3 years ago

Answer:

A hypothesis is a tentative/ preliminary statement of the relationship between two or more variables. <u>It is a specific, testable prediction about what you expect to happen in a study.</u>

Explanation:

In science, the hypothesis is an idea or explanation that you then experience/test through study and experimentation. Outside science, theory or guess can also be called a hypothesis. The hypothesis is nothing more than an unbridled, wild guess but less than a well-established theory.

So, we can conclude that <em>The hypothesis</em><u> is a simple statement that defines what you think the outcome of your experiment will be.</u>

<em>Hope</em><em> </em><em>this helps</em><em>.</em><em>.</em><em> </em>

<em>Good</em><em> </em><em>Luck</em><em>!</em>

GarryVolchara [31]

Answer:

The correct answer will be option-C

Explanation:

The plant absorbs the sunlight to perform photosynthesis which helps produce the sugar molecule used by the plants.

The plants absorb maximum sunlight at two wavelengths that are red and blue wavelength by chlorophyll and other pigments. The efficiency of photosynthesis is also measured maximum at these two active wavelengths called action spectrum.

In the given question, since the efficiency of photosynthesis has been discussed which could be measured with the production of oxygen and consumption of carbon dioxide. The experiment performed by the Engelmann showed that aerobic bacteria got concentrated in the blue and red wavelengths as the output of the photosynthesis were observed maximum.

Thus, the selected option is the correct answer.

Fudgin [204]

Complete question:

In a separate study, 68 rock pocket mice were collected from four different, widely separated areas of dark lava rock. One collecting site was in Sonora, Mexico. The other three were in Chihuahua, Mexico. Dr. Nachman and colleagues observed no significant differences in the color of the rocks in the four locations sampled. However, the dark-colored mice from the three Chihuahua locations were slightly darker than the dark-colored mice from the Sonora population. The entire Mc1r gene was sequenced in all 68 of the mice collected. The mutations responsible for the dark fur color in the Sonora mice were absent from the three different populations of Chihuahua mice. No Mc1r mutations were associated with dark fur color in the Chihuahua populations. These findings suggest that adaptive dark coloration has occurred at least twice in the rock pocket mouse and that these similar phenotypic changes have different genetic bases.

How does this study support the  concept that natural selection is not random?  

Answer:

The study supports the  concept that natural selection is not random because in different areas with the same or very similar environmental characteristics, the same phenotype was produced by different types of mutations.  

Explanation:

All of the sampled animals are inhabiting dark substrate. Probably animals needed to camouflage to survive. Natural selection must have driven them to produce dark color, similar to the substrate color. So animals from the different regions suffered different mutations that drove them to have almost the same dark fur color. The environmental condition is favoring the same phenotype.
