which of the following is not a reactant needed for photosynthesis
A. sunlight
B. oxygen
C. carbon dioxide
D. water
Answer:
I think it B
Explanation:
By definition of photosynthesis, oxygen is not a reactant needed for photosynthesis.
First, you have to know that photosynthesis is a metabolic process carried out by certain cells of autotrophic organisms, that is, those that have the capacity to make their own food, such as plants.
With this process, plants capture the energy of sunlight and transform it into chemical energy, to produce organic matter.
Photosynthesis takes place in 2 stages:
In the first stage the plants absorb water from the soil through the roots. Through their stems they transport it to their leaves. In these it meets the sunlight captured by chlorophyll, which breaks the water molecule, separating hydrogen (H) from oxygen (O2).The other stage is capturing carbon dioxide. This provides the carbon and oxygen atoms that, together with hydrogen and stored energy, will form the glucose molecule, from which compounds are produced that are the basis of food for plants and other living beings.Then, sunlight, carbon dioxide and water are needed for the photosyntesis, while oxygen is released to the environment.
This is sunlight, carbon dioxide and water are reactants needed for photosyntesis, and oxygen is not a reactant needed.

during a rainy spring, where are you most likely to find surface runoff
Answer:
there is only one surface in which we can run off in rainy season and that is room
Explanation:
steffie matt
Answer:
On a sloped parking lot
Explanation:
Surface runoff can be referred as the flow of water, that occurs when the excess water flows from the storm water, melt water, flood, rain streams and rain fall. The fast moving water current takes along with it superficial layers like surface and sub- surface layers of soil. Hence, causes water erosion of soil. The slope parking lot will favor, surface runoff more likely than in a grassy prairie, mulched flower bed, or in a sand pit because the slope will provide a surface for free flow of water. There are chances that water gets absorbed by the soil in the grassy prairie, mulched flower bed and sand pit. Whereas the slopy surface of parking lot will not allow the water retention by soil, instead will accelerate the flow of water.

In biological molecules, carbon,nitrogen, oxygen often form covalent bonds with hydrogen.Arrange these Bonds from most polar to least polar: C-H, N-H,O-H
Answer:
The order of polarity from most polar to least polar is as follows:
O-H > N-H > C-H
Explanation:
The polarity of a substance is a function of the charges of the ionic elements that makes up the substance. A bond between two ions is considered polar if it is between a negatively charged and positively charged ions. Hence, the stronger the charges of the ions in the bond, the more the polarity.
In this question, hydrogen is said to form covalent bonds with carbon, oxygen and nitrogen in biological molecules. However, the covalent bonds formed will not possess the same degree of polarity.
The bond between oxygen and hydrogen (O-H) is considered most polar amongst these three because OXYGEN atom is the most electronegative among the three ions. Hence, it will pull more electrons to itself and make the hydrogen ion more electropositive. This is followed by the bond between nitrogen and hydrogen (N-H) because nitrogen is more electronegative than carbon. The least polar is the bond between carbon and hydrogen as carbon is the least electronegative, hence, will not be able to pull electrons from hydrogen effectively.
The order from most polar to least polar is: O-H > N-H > C-H
SpongeBob loves to garden and wants to grow lots of pink flowers for his pal Sandy. He bought a special Flower Power fertilizer to see if it will help plants produce more flowers. He plants two plants of the same size in separate containers with the same amount of potting soil. The places one plant in a sunny window and waters it every day giving it fertilizer each day. He places the other plant on a shelf in a closet and waters it every day but does not give it any fertilizer. The plant in the sunny window ended up producing many more flowers than did the plant in the closet. Should SpongeBob conclude that giving Flower Power fertilizer to plants will cause the plant to produce more flowers
Answer:
No
Explanation:
It would be wrong for SpongeBob to conclude that giving flower power fertilizer helps the plant to produce more flowers based on the experimental design.
There are fundamental flaws in the experimental design that could make the conclusion to be wrong:
The two plants were not subjected to the same conditionsThe sample size is too smallIn order to investigate if the flower power fertilizer has the capacity to help the plant to produce more flowers, the two plants used should have been subjected to the same conditions barring only the fertilization application. Whatever difference that is observed in the number of flowers produced can then be attributed to the fertilizer.
Also, the number of plants for each group (with and without fertilizer) is too small to arrive at a reliable conclusion. In scientific investigations, replicating measurements increases the statistical power of the resulting data and raises the reliability of the conclusion.

Explain (in one or two lines) the function of the followings:
(a) Promoter
(b) tRNA
(c) Exons
Answer:
In genetics, a promoter is a sequence of DNA to which proteins bind that initiate transcription of a single RNA from the DNA downstream of it. This RNA may encode a protein, or can have a function in and of itself, such as tRNA, mRNA, or rRNA. Transfer ribonucleic acid (tRNA) is a type of RNA molecule that helps decode a messenger RNA (mRNA) sequence into a protein. tRNAs function at specific sites in the ribosome during translation, which is a process that synthesizes a protein from an mRNA molecule. Proteins are built from smaller units called. An exon is the portion of a gene that codes for amino acids. In the cells of plants and animals, most gene sequences are broken up by one or more DNA sequences called introns.

b. In 1979, the estimated elephant population was 1.3 million and in 2007 it was 640,000. By approximately what percentage did the elephant population decline over this time period? (Show your work.) How does this compare to the change in range over this same time period?
Answer:
The initial amount, 1.3 million = 1,300,000 is the 100%.
now, 640,000 is a given percentage (lower than 100%) of that.
How we can find it?
suppose that 640,000 represents an x%.
Then we have that the quotient between the actual quantities and the percentages must be the same
(640,000/1,300,000) = x%/100%
x% = (640,000/1,300,000)*100% = 49.23%
Then the percentage declined is:
100% - 49.23% = 50.77%
The other question can not be answered with the given information.
In order to calculate the percentage decline over the period of time between 1979 and 2007, the general formula for percentage change will be applied. This is as follows:
[tex]\frac{B-A}{A} \times 100[/tex]
where:
A = final value
B = initial value
In this problem:
A = Initial population = 1,300,000
B = Final population = 640,000
Applying this formula to the problem, the percentage change in population between 1979 and 2007 is as follows:
[tex]\frac{B-A}{A} \times 100\\\\\frac{640,000 - 1,300,000}{640,000} \times 100 \\\\\frac{-660,000}{1,300,000} \times 100\\\\= \frac{-66,000,000}{1,300,000} \\\\= -50.769 \%\\= 50.77\% \\Note\ that\ the\ minus\ sign\ denotes\ a\ decline.[/tex]
B: The change in range over this period of time is the difference between the final population and the initial populations, which is calcalated thus:
B - A (as explained above)
= 640,000 - 1,300,000 = - 660,000 (the minus sign still shows a decline)
While the percentage shows a "relative change" in terms of percentage, the change in range shows an absolute or actual change.
