Answer:

a. conservative replication

b. semi conservative replication

c. dispersive replication

d. discontinuous replication

e. continuous replication

The CORRECT ANSWER IS C.

c. dispersive replication

Explanation:

The attached image shows a single band that becomes lighter (in volume) and increase in darker intensity (in times of color) is revealed with consecutive replications. The major pattern that would produce these outcome is dispersive replication.

Conservative replication do reveal two bands (a 14N for the wholly latest molecule, and a 15N for the totally antiquated molecule) after the initial replication. Therefore, this wholly wrong.

Semi-conservative replication reveal an individual band of transitional weight after the initial replication, followed by two bands following the second replication (one of transitional weight, and the other at the 14N position). These two bands is observed in each following replication, with the transitional weight becoming lighter in color as the 14N band is seen to appear darker in color.

The real pattern gives an individual band that pinpoints to all molecules in an individual replicative cycle possessing the same constituents.

Dispersive replication, has its molecules to be a blend of old (15N) and new (14N) strands. Each replication raises the ratio of new to old strands as it explains the reason an individual band is shown raised (lighter in weight) with every replication.

Jackie was born with _____ , the absence· of long· wavelength cones .

SpyIntel [72]

PROTANOPE. These are the individuals that suffers form color blindness. This color blindness is due to the absence fo the L- cones which are cones that are sensitive to long wavelength. Cones are one of the three types of photoreceptos found in the retina. These are responsilble for color vision and function best in a brightl light. In contrast to the rods which works on dim light. Cones are found in the fovea.

Volgvan

During a decomposition reaction, a compund partitions into it's components. This is a type of a chemical reaction where a larger/more complex compund is broken down into simpler elements or compounds which were initially combined in a chemical reaction.This type of reaction often requires an energy source such as heat or light to break down the compound.

Which breast condition is a malignant disorder? mammary duct ectasia fibroadenoma papilloma carcinoma?

s344n2d4d5 [400]

The correct answer is carcinoma. Mammary duct ectasia, papilloma and fibroadenoma are benign conditions of the breast. Breast carcinoma is malign cancer that develops from breast tissue. Breast cancer is the most common cancer among women which can be the result of genetic or lifestyle factors. Invasive ductal carcinoma (IDC) is the most common type of breast cancer.
