Article name: New Research Shows Plants Are Photosynthesizing More in Response to More CO2 in the Atmosphere
BY LAWRENCE BERKELEY NATIONAL LABORATORY DECEMBER 17, 2021
Answers
Article states that "plants take up carbon dioxide from atmosphere and convert it into food."
Explain how article supports the law of the conservation of matter?1.This supports the law of conservation of matter, which states that matter cannot be created or destroyed, and can only be transformed from one form to another. In this case, carbon dioxide in atmosphere is transformed into organic matter in form of plant tissue.
2. According to the article, new research shows that plants are photosynthesizing 5% more in response to increased levels of CO2 in atmosphere.
3.The article states that 5% increase in photosynthetic rate translates to additional 5 billion tons of carbon being removed from atmosphere each year.
4.Article suggests that increase in photosynthetic efficiency may be a result of plants having more CO2 available to them, which stimulates photosynthesis.
5.Laboratory procedure used to quantify photosynthetic efficiency involves measuring amount of chlorophyll fluorescence emitted by plant. This fluorescence provides a measure of amount of light energy absorbed by plant during photosynthesis.
6. Field procedure used to quantify photosynthetic efficiency involves measuring amount of carbon dioxide taken up by plant during photosynthesis. This is done by placing plant in sealed chamber and measuring change in carbon dioxide concentration over time.
7.The article suggests that potential "saturation" of carbon dioxide in the atmosphere could lead to a leveling off of increased photosynthetic rates observed in plants.
9.The potential "saturation" of carbon dioxide in atmosphere refers to point at which plants would no longer be able to increase photosynthetic rates in response to higher levels of atmospheric CO2. If ecological photosynthetic rates were to reach saturation, it would mean that plants would no longer be able to remove more carbon dioxide from atmosphere through photosynthesis.

3. For each environment below, describe why you think it would have a high or low
rate of speciation.
A rugged mountain terrain (1 points)
A large, open forest (1 points)
An island in the ocean (1 points)
Answers
For each environment below, describe as, Islands frequently have a low carrying capacity, which may promote competition and resource allocation among species, further accelerating speciation.
A challenging mountainous terrain : rapid speciation Due to changes in height, geology, and climate, rocky mountain terrain often consists of isolated pockets of habitat. The genetic isolation of populations can result from these isolated areas acting as obstacles to gene flow. Genetic variations can build up over time, leading to reproductive isolation and ultimately to speciation. Furthermore, the extreme conditions found in rocky mountain terrain, such as harsh climates, steep slopes, and a lack of resources, might encourage speciation by driving adaptation and specialization among species.A large, open forest : Low rate of speciation, A big, open forest usually offers continuous habitat and fewer physical obstacles to gene flow. Individuals can travel about more easily as a result, encouraging gene flow and minimising genetic isolation among communities.An island in the ocean : High speciation rate, Islands frequently exhibit isolation, which can cause population genetic diversity. Islands frequently have little gene flow with mainland populations because of their isolation, which can result in genetic isolation and the possibility of speciation. Additionally, islands often feature distinctive biological characteristics that might encourage speciation and drive adaptive evolution, such as diverse climatic patterns and resource availability.To know more about environment

moves substances out of the cell.
Answers
Answer:
Active transport mechanisms require the use of the cell’s energy, usually in the form of adenosine triphosphate (ATP).
Explanation:
If a substance must move into the cell against its concentration gradient, that is, if the concentration of the substance inside the cell must be greater than its concentration in the extracellular fluid, the cell must use energy to move the substance. Some active transport mechanisms move small-molecular weight material, such as ions, through the membrane.
In addition to moving small ions and molecules through the membrane, cells also need to remove and take in larger molecules and particles.

The cross AB/ab X ab/ab produces the following progeny: AB/ab 391, ab/ab 401, aB/ab 406, Ab/ab 386. From these data, one can conclude that the A and B loci assort independently.
A. True
B. False
Answers
Answer:
B
Explanation:
The two loci did not assort independently.
In order to check for independent assortment or otherwise of the result from the cross, Chi-square is used to see if the result conforms with that of Mendelian standard of 9:3:3:1.
Phenotype Observed f Expected f \(X^2\) = \(\frac{(O - E)^2}{E}\)
AB/ab 391 9/16 x 1584 = 891 \(\frac{(391-891)^2}{891}\) = 280.58
ab/ab 401 3/16 x 1584 = 297 \(\frac{(401-297)^2}{297}\) = 36.42
aB/ab 406 3/16 x 1584 = 297 \(\frac{(406-297)^2}{297}\) = 40.00
Ab/ab 386 1/16 x 1584 = 99 \(\frac{(386-99)^2}{99}\) = 832.01
Total \(X^2\) = 280.58 + 36.42 + 40.00 + 832.01 = 1,189.01
Degree of freedom = 4 - 1 = 3
Tabulated \(X^2\) at degree 3 freedom and 95% level = 7.815
The calculated \(X^2\) value is more than the tabulated value. Therefore, we conclude that the outcome of the cross is not in agreement with Mendelian standard and hence, the A and B loci did not assort independently.
The correct option is B.

also be a source of genetic variation. Mutations also cause variations in genetic sequences.
Mutations are always harmful." Is this a true or false statement, explain why?
Answers
This given statement about "Inherited genetic variations" is mostly false.
What are the true statement about Inherited genetic variations?It is true that inherited genetic variations are caused by genetics only, specifically the process of meiosis, crossing over and assortment in the development of sex cells, and the random joining of sex cells can also be a source of genetic variation.However, mutations do not always cause harmful variations in genetic sequences. Mutations can be beneficial, neutral or harmful, depending on the context. For example, some mutations can lead to genetic diseases, but others may confer resistance to certain diseases, or result in a beneficial trait such as increased immunity.Moreover, even if a mutation is harmful, it does not mean it will always be harmful. The effects of a mutation can be influenced by other genetic factors and environmental factors, that can affect the phenotype.Therefore, while it is true that inherited genetic variations are caused by genetics only and mutations can cause variations in genetic sequences, the assertion that all mutations are harmful is not accurate.To learn more about inherited genetic variations refer:

Answers
Based on the definition of supplementary angles, the angles are: 2° and 178°.
What are Supplementary Angles?Angles that are supplementary have a sum that equals 180 degrees.
Let the measure of the supplement be x.
The other angle would be: (x + 176)
Therefore, we would have:
x + (x + 176) = 180
2x + 176 = 180
2x = 180 - 176
2x = 4
x = 2
One of the angles is, 2°
