Answer:
Wave is a water disruption that causes ripples that can be big or small
Waves occur because of the gravitational pull from the moon.
Answer:
In science, a wave is defined as a transfer of energy. Ocean waves are caused by wind moving across the surface of the water. The friction between the air molecules and the water molecules causes energy to be transferred from the wind to the water. Waves are mostly caused and come from wind.

How do you get vegetables to the market? Write the procedures in brief.
1.
Marketing is one of the most important factors in determining the success of any fruit and vegetable farming enterprise. Marketing includes all the operations and decisions made by producers. These decisions range from deter-mining the most marketable crops for production to deciding how to best deliver quality produce to the consumers at a profit. However, contrary to popular belief, marketing does not begin after a crop is produced. Instead, marketing alternatives need to be considered even before production takes place.
2.
Recent environmental and food safety concerns in the United States produce sector have brought about increasing interest in organic fruit and vegetable production as an alternative to traditional fruit and vegetable enterprises. As a result, the production and marketing of organic crops has expanded steadily during the 1980s. However, as more organic producers enter the industry and it becomes more and more competitive, existing producers are forced to become better growers and more effective marketers.

How can the arrangement of atoms help explain how the white phosphorus and red phosphorus can both be pure phosphorus substances?
Answer:Phosphorus is a chemical element with symbol P and atomic number 15. A multivalent nonmetal of the nitrogen group, phosphorus as a mineral is almost always present in its maximally oxidized state, as inorganic phosphate.
Explanation:
Chemical element phosphorus has the atomic number 15 and the letter P in its symbol. Phosphorus, a multivalent nonmetal belonging to the nitrogen group, is generally always found in the form of inorganic phosphate, which is phosphorus in its maximally oxidized state.
What is phosphorus?The mineral phosphorus, which is also available as a supplement, is naturally present in many foods. It serves the body in a multitude of capacities. It is a crucial component of cell membranes, bone, and teeth. It maintains a healthy range of blood pH and aids in the activation of enzymes.
All tissues and cells must have phosphorus for growth, maintenance, and repair as well as for the creation of DNA and RNA, the genetic building blocks. The balance and usage of other vitamins and minerals, including vitamin D, iodine, magnesium, and zinc, depend on phosphorus as well.
Thus, Chemical element phosphorus has the atomic number 15.

What is the best explanation for the difference in shape between the two drops shown below
Answer:
A
Explanation:
I think the answer is A because Hexane is a non-polar solvent and A is the only answer choice that says its non polar. Im sorry if it is incorrect
The best explanation for the difference in shape between the two drops given in image is - Option D. glycerin is polar and has greater cohesion than hexane.
Polarity is the physical characteristics of liquid that allows them to stick to other substances which is called adhesion. Polar molecules also attracted to itself, and this physical trait called cohesion. Water's most common form in the air, a droplet is formed due to this cohesion.
Hexane is a nonpolar solvent that has less electro negativity charge therefore, they do not have hydrogen bonding and there is less cohesion in the molecules.Glycerin is a polar solvent that allows its molecules to attract itself that is cohesion present and lead to more of droplet shape.Thus, the correct answer is - option D.

The Drosophila genes for white eyes (w), cut wings (ct), and tan body (t) lie at map positions 2.00, 15.0, and 21.0, respectively. Of 1000 progeny, 7 are double crossovers. What is the degree of interference
Answer:
The coefficient of interference, I, is 0.1 (10% expressed as a percent)
Explanation:
Available data:
genes for white eyes (w), cut wings (ct), and tan body (t) lie at map positions 2.00, 15.0, and 21.0, respectivelyOf 1000 progeny, 7 are double crossovers.The coefficient of interference, I, is complementary with CC.
I = 1 - CC
To calculate the coefficient of coincidence, CC, we must use the next formula:
CC= observed double recombinant frequency/expected double recombinant frequency
Note:
observed double recombinant frequency=total number of observed double recombinant individuals/total number of individuals expected double recombinant frequency: recombination frequency in region I x recombination frequency in region II.By knowing the positions of genes, we can estimate the distances in MU between them per region.
The distance between w and ct genes is 15 - 2 = 13 MUThe distance between ct and t genes is 21 - 15 = 6 MUNow that we know the distances, we can estimate the recombination frequencies by dividing each distance by 100.
recombination frequency of w-ct region = 13MU / 100 = 0.13recombination frequency of ct-t region = 6MU / 100 = 0.06Now that we know the recombination frequencies in each region, we can calculate the expected double recombinant frequency, EDRF, like this:
EDRF = recombination frequency in region I x recombination frequency in region II.
EDRF = 0.13 x 0.06 = 0.0078
Now, by knowing the total number of individuals in the progeny (1000) and the number of double crossovers (7), we can calculate the observed double recombinant frequency, ODRF:
ODRF = number of double crossovers / total number of individuals
ODRF = 7/1000 = 0.007
Finally, with the values of EDRF and ODRF, we can calculate the coefficient of coincidence, CC.
CC = ODRF/EDRF
CC = 0.007 / 0.0078
CC = 0.9
And by knowing the CC we can also get the coefficient of interference, I.
I = 1 - CC
I = 1 - 0.9
I = 0.1 = 10% (expressed as a percent)

All of the following are true of spermatogenesis EXCEPT: Question 4 options: One spermatogonium produces 4 spermatids Genetically diverse spermatids are created. The products are spermatozoa that each have a head, midpiece and tail. DNA replicates once, but cells divide twice. Spermatids containing 23 chromosomes (1n) are produced.
Answer: The products are spermatozoa that each have a head, midpiece and tail.
Explanation:
The spermatogenesis can be defined as the process of gamete production in human males. It takes place in the testes in males. In this process the spermatids are produced which are four in number through reductional cell division called as meiosis. Each spermatid is haploid in number and the genetic material present in each is diverse as a result siblings are not identical to each other. The spermatozoa is an immature sperm cell which develops head, middle piece and tail. But it is not a precursor of production of sperm cells via cell division.

why plant cells require sunlight to make organic compounds, according to Gibbs's theory of free energy?
O The photosynthetic reaction releases free energy to the surroundings.
O The photosynthetic reaction's free energy is in equilibrium.
The reactants of photosynthesis have less free energy than the products,
The change in free energy (AG) of the photosynthetic system is less than zero.
Answer:
I'm not sure if this is correct but I think it's C
Answer:
C ( I think)
Explanation:
If a chemical reaction requires an energy input rather than releasing energy, then the ∆G for that reaction will be a positive value. In this case, the products have more free energy than the reactants. Thus, we can think of the reactions’ products as energy-storing molecules. We call these chemical reactions endergonic reactions, and they are non-spontaneous. An endergonic reaction will not take place on its own without adding free energy.

if you are at 120X and the field diameter is 8.0 mm what is the field diameter if you go to 30X magnification?
Answer:
32 mm
Explanation:
The field of view is the total area visible through the microscope . The diameter of the field of view can be measured.
There is an inverse relationship between the magnification and the field diameter. As magnifications decreases, the field diameter increases by the same proportion, and as magnifications increases, the field diameter decreases by the same proportion.
The relationship between field diameter and magnification is:
magnification of A * field diameter of A = magnification of B * field diameter of B
120X * 8 mm = 30X * B
B = 120X / 30X * 8 mm
B = 32 mm = 32000 μm
The field diameter of 30X magnification is 32 mm (32000 μm)
