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.

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:

In 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.

Answer:

D. 204

Explanation:

proportion : 12/70 = 35/x

70(35)=12x

2450=12x

204.166667=x and round it to make it 204.

The best estimate of the number of fish in the pond is 204. Thus, option D is correct.

Calculation:

proportion : 12/70 = 35/x

70(35)=12x

2450=12x

204.166667=x and round it to make it 204.

Average speed has been defined as the total distance travelled in total time taken it means that we can calculate the average speed obtained by an object .

Mathematically,

Average Speed = Total distance travelled/Total time taken

It's S.I unit is meter/second

Average speed is a scalar quantity it means that it has only magnitude not direction.

Ecosystem has been the branch of science that deals with the study of relationship between living organisms and natural phenomena. Ecosystem has the system in which both living as well as nonliving organisms are present in a particular location.

Green plants contain chlorophyll and they prepare there own food in the presence of sunlight and the process is known as photosynthesis. In the process of photosynthesis light  energy converted into chemical energy.

Therefore, The best estimate of the number of fish in the pond is 204. Thus, option D is correct.

Calculation:

proportion : 12/70 = 35/x

70(35)=12x

2450=12x

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.

Explanation:

The structure that is not a part of endomembrane system is chloroplast. The correct option is B.

The endomembrane system is a membranous component system. The membranes of the nucleus, the endoplasmic reticulum, the Golgi apparatus, lysosomes, endosomes, vesicles, and the plasma membrane are all part of it. It doesn't include mitochondrial chloroplast membranes.

The endomembrane system is a network of membranes in the cell that serve to reconfigure, transfer, and bundle proteins and lipids.

The endomembrane system is a collection of eukaryotic biological membranes and organelles that work with each other to modify, package, and transport lipids and proteins.

Thus, the correct option is B.

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

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.

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:

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.
