Snezhnost [94]3 years ago

Answer:

The correct answer would be:

                  A         G          C         T

Human:   31          19          19       31

Cow:         28         22      22         28

Salmon:     29       21       21         29

Wheat        27      23        23        27

Yeast         31         19       19         31

Explanation:

According to the rule of Chargaff which states or explains the amount of the A, T, G, and C bases in the DNA molecule. It says that the DNA of any organism should have a pyrimidine and purine ratio of 1:1. This means the amount of A would be equal to T and the amount G should be equal to the amount of C.

It also says that the amount of a and G would be equal to the amount of C and T. So on the base of this we can find the missing value in the table:

                    A         G          C         T

Human:   31          19          19       31   (A= T and G=C)

Cow:         28         22      22         28  (A= T and G=C)

Salmon:     29       21       21         29   (A= T and G=C)

Wheat        27      23        23        27 (100 - A+T = G+C)

Yeast         31         19       19         31 (A= T and G=C)

1. During which process of the hydrologic cycle does the sun heat surface water, causing the water to change from its liquid sta
xenn [34]

Answer:

1. D. Evaporation

2. A. A closed lake has no outlet stream.

3. C. The angle of the slope

4. C. Granite

Explanation:

1. The process through which water changes its state from liquid to gaseous is known as evaporation. A source of energy is required for this process to occur, energy that is provided by solar heat in this case. The opposite process in which water changes state from gas to liquid, is known as condensation. Precipitation is the process in which the condensed water reaches the Earth’s surface under the force of gravity. During infiltration, water on the ground surface enters the soil.  

2. A closed lake is defined by the lack of any outflow. Thus, any water that does not evaporate, will remain in this type of lake indefinitely.

3. The only criterion not used to describe a mass movement event is the angle of the slope. For such an event, the type of motion is the most important characteristic together with the physical characteristics of the material.

4. Granite is a highly consolidated material and thus it has a very high integrity. The other materials listed have inferior characteristics.

5. Soil erosion is a displacement process that occurs naturally though the action of water and wind. On a steep slope, no soil formation occurs, because, due to gravity, all the eroded material will be transported to another location. Thus, at the slope’s location, no soil formation occurs.

At the salinity of average seawater, what happens to density as the temperature increases? Is this also true of fresh water? Bra
ivanzaharov [21]

Answer:

The density of water increases as the salinity increases. The density of seawater (salinity greater than 24.7) increases as temperature decreases at all temperatures above the freezing point. The density of seawater is increased by increasing pressure.
