What are the genotypic differences between F-, F+ and Hfr cells?

Biology
1 answer:
Kitty [74]3 years ago
5 0

Answer:

The fertility factor or the F factor signifies a plasmid in some bacteria, which allows the conduction of genetic substance from a donor cell to the recipient by the process of conjugation, leading to recombination.  

The genotypic difference between the F- cells, F+ cells, and the Hfr cells are that the F- cells are devoid of the F factor, the F+ cells possess autonomous F factor, that is, a segment of DNA, which can replicate autonomously in the cell. In case of Hfr, the F factor is integrated into its chromosomal DNA, thus, they carry an integrated F factor.

The amount of water that evaporates from earth is _____.
amid [387]

Answer:

The amount of water that evaporates from earth is roughly equal to the amount that falls as precipitation.

Explanation:

In the hydrological cycle, evaporation consists of the conversion of liquid water into water vapor, which reaches the atmosphere. Once the water vapor condenses produces precipitation in the form of rain, snow or hail.

<u>On the earth the amount of water that evaporates is proportional to the water that falls as precipitation</u>. The mass of ocean water is substantially greater than the amount of land, so variations in the proportion of evaporated water and precipitation occur in the hydrological cycle:

  • <em>In the oceans, evaporation is greater than the precipitation that occurs. </em>
  • <em>On the continents - firm land - evaporation is less than precipitation. </em>

This produces a certain grade of compensation in which, globally, the amount of water that evaporates from the earth is roughly equal to the amount that falls as precipitation.

Meteorologists take careful measurements of daily minimum temperatures, maximum temperatures, and precipitation (rainfall). The
Vinil7 [7]

Months with higher temperature have more rainfall.

Explanation:

From the presented graph, we can see that all three parameters are following a same trend. When the maximum temperatures increase, the minimum temperatures increase too, and the rainfall increases as well. When the maximum temperatures decrease, the minimum temperatures decrease, and the rainfall decreases too.

There is a simple explanation for the connection of higher temperature and more rainfall in Scotland. Scotland is located on an island, thus it is heavily influenced by the sea. When the temperature is higher, the humidity is higher, and in accordance to that more rainfall occurs. When the temperature is lower, the humidity is lower, so there is less rainfall, or instead of rainfall the precipitation can be manifested as snowfall.
