-removing a few bases for DNA polymerase
-add a few bases for DNA polymerase
-removing a few bases for helicase
Answer:
The correct answer is - add a few bases for DNA polymerase
Explanation:
A short extended nucleic acid composed of ssRNA molecule. This is a molecule that synthesize a primer initialy and later again lay down a primer after the opening of replication fork by DNA helicase.
It sysntheisze before and after the helicase and follow the helicase in order to prepare for the replication process. Thus, adding a few bases for DNA polymerase is main job of RNA primase.
Which is NOT a force causing plates to move?
ridge push
slab pul
volcanism
ConveCtion
Ob
Plates movement also known as tectonic shift is caused by ridge push, slab pull and convection. Volcanism is not involved in plate movement. Thus, correct option is C.
Which forces causes Plates Movement?The heat within the interior of the planet causes the plates to move, sometimes toward and sometimes away from each other. This movement is called plate motion or tectonic shift.
The forces that drive plate movement includes convection in the mantle, ridge push and slab pull. The heat from radioactive processes within the planet's interior causes the plates to move.
Convection currents are the process in which materials inside the mantle heat up and rise to the surface and the cooler liquid sinks, as the cooler liquid sinks it then heats up and rises again. These currents cause the tectonic shift.
Slab pull is the pulling force exerted by a cold and oceanic plate to plunge into the mantle due to its weight. The theory states that difference in density causes the plate to sink into the mantle.
Therefore, the correct option is C.

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.

Volcanoes can form near coastal regions where an oceanic plate [blank] below a continental plate
Answer:
Subducts
Explanation:
According to Merriam Webster and TheFreeDictionary, the definition of subduct is "A geologic process in which one edge of one crustal plate is forced below the edge of another." Since this sentence indicates that an oceanic plate sinks under the continental plate, therefore I believe the fill-in-the-blank word would be 'subducts' or a similar word.

Which component is found in nonvascular plants?
Leaves
Stems
Chlorophyll
Roots
Answer:
Chlorophyll
Explanation:
because they lack roots, stems, and leaves.
The component that can be found in non-vascular plants is chlorophyll. The correct option is C.
What is chlorophyll?Chlorophyll is a pigment that gives plants their distinctive green colour and aids in photosynthesis, which enables plants to produce their own food.
Plants (including algae) can photosynthesize, or use sunshine to change simple molecules into organic compounds.
Chlorophyll makes this possible. The most common kind of chlorophyll found in algae and green plants is chlorophyll a.
Plants lacking a circulatory system made up of xylem and phloem are referred to as non-vascular plants. They may instead have more basic tissues with tailored capabilities for the internal transfer of water.
Mosses, hornworts, and liverworts are examples of nonvascular plants. They don't have leaves, stems, or roots.
Nonvascular plants require a damp environment, are low-growing, and reproduce using spores.
Thus, the correct option is C.

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)

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.

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)
