Ductus Arteriosus is a blood vessel normally present in fetuses during development. The blood vessel is designed to bypass the pulmonary artery and brings blood to the Descending Aorta, as the fetus cannot breath through the lung (being as they are fluid filled). This is normally not a problem because oxygenated blood comes from the mother's blood supply.

Patent Ductus Arteriosus, is what happens when that vessel does not close. While not as dangerous as other congenital defects. However, because there is still a bypass, blood that normally need to be oxygenated by going through the pulmonary arteries to the lungs, can be diverted and placed into the blood stream without vital oxygen. This condition may eventually lead to CHF (congestive Heart Failure) and Pulmonary Hypertension if not treated.

This part is used to bring the specimen into sharp focus. This part causes a very small up and down motion when used.
Mekhanik [1.2K]

Answer:

Fine focus.

Explanation:

If you're referencing a microscope, then it would be fine focus. Coarse focus is a basic focus used to properly see a specimen, while fine focus enhance clarity and precision. To use both, you have to gently twist a knob until you can see the specimen at a desired clarity.

Here's a reference image if you need it, it's labeled all the parts of a microscope.

For sucrose to be moved from a leaf (source) cell to a root (sink) cell, sucrose is first actively transported into the phloem f
Natali5045456 [20]

Answer:water diffuses into the phloem from the xylem and sucrose moves to the sink

Explanation:Translocation is the movement of ready produced food substances from the site of production to places in the plant where food is needed. such as the roots.the place where food is produced is called the source, the the place where food is used up is called the sink.the leaves are the source in a plant.photsoynthates, which is the plant manufactired food, may move up and down the stem ,majorly to areas of storage and growth.

Surose is the major intermediate product of photosynthesis.it is the form in which sugar is transported.it is conducted by the phloem vessels.this takes place in the long sieve elements that forms the sieve tubes

The high percentage of sucrose in the phloem sap causes water to pass into it from the xylem. This then causes the sap to move from source to sink.

At the sink, sucrose diffuses out of the phloem.it is either stored up or used for growth and repairs

You try to generate E. coli mutants by inducing pyrimidine dimers through UV exposure to bacteria on Petri plates. You confirm t
spin [16.1K]

Answer:

The correct answer is option E. "direct repair using photolyase has removed many of the pyrimidine dimers from the DNA in an error-free manner, so there are fewer lesions for SOS repair to process".

Explanation:

Photolyase is a type of enzyme that catalyses DNA repair from damage caused by exposure to ultraviolet light. Photolyase requires activation by exposure visible light, particularly from the violet end of the visible spectrum. If the Petri plates of the bacteria exposed to UV are located in an incubator that is closely at a large sunny windows, it is very likely that the bacteria is performing direct DNA repair using its photolyase enzymes.
