Answer:

The right answer to this question is: Penicillium does not seem to have sexual phase

Explanation:

        This classification of fungi, Deuteromycota, are imperfect, they don't have sexual reproduction at all, at least the scientists couldn't find it until now. With that, the genetic variability is pretty low on this population,

          They do their reprodution using something called asexual conidiophores, and through this, they can generate their descendents.

Microscopic plants called algae grow inside the top layer of sea ice in the Antarctic if enough sunlight reaches that layer of i
MrRa [10]

Answer:

The correct answer is: (A).

Explanation:

  • In the question, it is mentioned that the algae can grow under the conditions of "enough sunlight" and "enough nutrients".
  • Sunlight reaches the algae, by first falling on the surface made up of ice and snow and then refracting from there into the top layer of the ice where the algae grows.
  • However, the capability of both snow and ice to reflect sunlight is far more than that of refracting sunlight.
  • Therefore, the amount of light received by the algae is similar in absence or presence of the layer of snow on the top layer of ice.
  • However, on deposition of snow on the layer of the ice, the weight of the ice increases and it sinks below into sea water.
  • This allows more nutrient rich sea water to percolate into the ice and reach the algae.
  • The algae receive more nutrients from the sea water and hence is capable undergoing better metabolism and growth.
  • Hence, more algae are produced under such a situation.

Meselson and Stahl's experiments proved that DNA replicates by which mode?
Irina18 [472]

Answer:

Semi-conservative

Explanation:

Meselson–Stahl experiment proved that DNA replication is a semiconservative process, feeding E. colo bacteria with different types of Nitrogen isotopes (N14 and N15).

Changing the type of radioactive compound in different times of bacteria grow, they could observe that both of the isotopes were present on the bacteria culture.

Basically, if the bacteria present both of them, the DNA was replicated semiconcervely.

Guess what? they show both! (See the image for more information)
