Bacterial cells were coinfected with two types of bacteriophage lambda: One carried the c+ allele and the other the c allele. Af

ter the cells lysed, progeny bacteriophage were collected. When a single such progeny bacteriophage was used to infect a new bacterial cell, it was observed in rare cases that some of the resulting progeny were c+ and others were c. Explain this result.

Answer:

Since the cells are being coinfected by 2 types of viruses, this can create heteroduplex areas. DNA repair systems normally correct the heteroduplex areas. In rare cases, the heteroduplex is not corrected and a chromosome containing the mismatch appears so a single bacteriophage particle can be generated. One DNA strand is c+, and the other strand is c. When such a bacteriophage infects a fresh bacterial host cell, some molecules are created by DNA replication.

How does upwelling affect coastal fisheries?
Bess [88]

Answer:

Upwelling improves the nutrient supply at coastal fisheries as the cold, nutrient-rich water replaces the warm, nutrient-poor surface water

Explanation:

The upwelling is simply the process through which the cold water rises up toward the surface, pushes and moves away the warmer water, until it gets warmer and is pushed by the colder water blow it. The cold water that rises toward the surface is nutrient-rich, while the warm surface water is nutrient-poor. By having the nutrient-rich cold water come toward the surface, the coastal fisheries have great benefit, as the more nutrients there are, the more fish there will be for them to catch.

Why don’t eclipses occur during any other moon phases besides the new and full moon?
Bad White [126]

Answer:

There's no eclipse at every full moon and new moon because the moon's orbit is inclined to Earth's orbit by about five degrees. Most of the time, the sun, Earth and moon don't line up precisely enough to cause an eclipse.

Explanation:

During a lunar eclipse, Earth comes between the Sun and the Moon, blocking the sunlight falling on the Moon. Earth's shadow covers all or part of the lunar surface.

daser333 [38]

In the genetic disease called ichthyosis, the skin is rough, brown, and scaly because the uppermost layer cannot peel off as easily as it should. what layer of the skin is affected in this disorder is epidermis.

Ichthyosis is a skin condition that turns the skin, thick, scaly and fleshy. Since it is genetic disorder, the genes are inherited from the parents. Of inherited from one parent, the skin condition are milk. But when genes are received from both the parents, the disease occurs in its most severe form, also called ichthyosis vulgaris.

Epidermis is the outermost layer of the skin. It is the body's first line of defense because it prevents any microbes entering the body. Besides, it also protects from mechanical injury, stops the loss of moisture and also reduces the effect of UV radiations.
