Answer:
Trees give off oxygen that we need to breathe. Trees reduce the amount of storm water runoff, which reduces erosion and pollution in our waterways and may reduce the effects of flooding. Many species of wildlife depend on trees for habitat. Trees provide food, protection, and homes for many birds and mammals.

A DNA microarray contains immobilized DNA that corresponds to different genes. The microarray is hybridized with fluorescently labeled DNA probes reverse transcribed from the control and experimental mRNA samples. The control probe is labeled with a red fluorochrome, while the experimental probe is labeled with a green fluorochrome. What will be the color of the spot representing a gene with moderately upregulated expression in the experimental sample relative to the control one
The color of the spot of a gene with moderately upregulated expression will be lime-green. A DNA microarray is a technique used to determine the expression level of many genes simultaneously.
A DNA microarray is a laboratory technique used to identify the genes that are being expressed in a cell.
A DNA microarray contains many tiny spots of specifically labeled cDNA samples referred to as probes, which can be hybridized by base complementarity to transcribed (mRNA) gene sequences.
In the DNA microarray, the probes can be fluorescently marked gene sequences.
After hybridization, the DNA microarray is then scanned in order to determine the level of gene expression of each mRNA that hybridizes with their corresponding probes on the slide.
In this case, green spots evidence genes that are being strongly expressed in the sample.

which population should display the highest growth rate?
One variable not mentioned in the description of the experiment that could affect the results of the investigation is reduced canopy cover. Describe the effect that canopy cover would likely have on the results of the investigation.
The canopy cover can affect the results of an investigation because a higher canopy cover is accompanied by a decrease in the availability of sunlight.
The canopy cover is the proportion of the ground covered by vegetation when it is viewed from vertically above the planted area.
The level of canopy cover affects light availability on the ground and also its microclimate, thereby this feature can also alter any biological experimental procedure by affecting the level and type of biodiversity.
A reduced canopy cover may alter any experimental outcome by increasing the energy/light input in the ground cover stratum, thereby likely affecting biodiversity.

Can sunlight change the distribution of traits in a population?(1 point)
No, because the environment can only change behaviors.
Yes, because the environment is the only factor that can change traits.
Yes, because the environment can factor into the distribution of traits.
No, because the environment can only change traits in individual organisms.
A number of factors including environmental factors (for example sunlight) can also play a role in how the traits in a particular population is distributed.
Sunlight can change the distribution of traits in a population because the environment can factor into the distribution of traits.
The distribution of traits is changed when factors in the environment change/evolve and influence natural selection. These environmental factors including sunlight alter the selection of traits passed to generations and can have an effect on the distribution of the traits on Earth.Learn more about environmental factors: https://brainly.com/question/3638961
The sunlight can be a factor for the distribution of traits in a population. Option C is correct.
Natural selection:
It is phenomenon in the evolution in which a population of species in distributed in the habitat or evolve by the certain traits that fits in the nature.
For example-
A population of a species have two types of traits,
1. Individuals that can bear the intense light.
2. Individuals that can not bear the intense light, prefer low light.
After several generation the whole population will divide in the groups according to their ability to bear the intensity of light.
It can also result in the new species that only wake up at night to avoid the sun.
Therefore, the sunlight can be a factor for the distribution of traits in a population.

with such a rich diverse array of life forms how are we able to live harmoniously with each other
Explanation:
Life on earth is incredibly diverse. Biological diversity is the variety of life on earth. This includes all the different plants, animals, and microorganisms. Life on earth is incredibly diverse. Biological diversity is the variety of life on earth. This includes all the different plants, animals, and microorganisms; the genes they contain; and the ecosystems they form on land and in water. Biological diversity is constantly changing. The source of this diversity is evolution, the process of gradual change during which new species arise from older species. Evolutionary biologists study the evolution of living things in everything from the microscopic world to ecosystems. There are so much duversity in life on the Earth because there are great numbers of species on the earth, the present day organism are the end product of about 3.5 billion years of organic evolution on earth.

Flavr Savr™ Tomato
Explanation:
The element lithium has two common isotopes: Li–6 and Li–7 If the average atomic mass of lithium is 6.94004 u, determine its percent isotopic abundances. Step by step and explain.
First we need to determine the average atomic mass of these isotopes.
The atomic masses of Lithium-6 and Lithium-7 are 6.0151amu and 7.0160amu respectively.
Now that we have that, we need to set up the relative abundance problem.
We can do that using the formula (M1)(x) + (M2)(1-x) = M(E)
Because you asked for details, I'll explain what each variable stands for-
M1 = the mass of one isotope
x = the relative abundance
M2 = the mass of the second isotope
M(E) = the atomic mass of the element from the periodic table
Therefor all we do now is plug in our respective variable.
M1 = 6.0151amu (Lithium-6)
x = unknown relative abundance
M2 = 7.0160amu (Lithium-7)
M(E) = 6.94004amu
Now the formula plugged in will look like this:
6.0151x + 7.0160(1-x) = 6.94004
Now doing some quick math, we can determine that x=0.07589
For the last step we need to find the percent abundance of each element, which is quite simple. We take X and multiply it by 100 to find Lithium-6, so 0.076 x 100 = 7.6%
and since then we use 1 - X, so 1 - 0.076 = 0.924
We take that and also multiply it by 100, so 0.924 x 100 = 92.4%
Conclusion:
The abundance of the Lithium-6 isotope is 7.6%, and the abundance of the Lithium-7 isotope is 92.4%.
