Which process tends to occur more quickly, natural selection or artificial selection? Why do you think this is so?
Monica [59]
Artificial Selection.

Natural selection progresses slowly & would take generations to complete while artificial selection may complete within days or weeks. This is because Natural selection is not as controlled as artificial selection.

Which is a characteristic of exponential population growth?
Rudik [331]

A characteristic of exponential population growth is that <u>resources are consumed exponentially during all phases </u>

Explanation:

Exponential growth is a type of growth where the population doubles its population size with each generation. Bacteria are the best examples of organisms that can exhibit this type of growth. However, just as the growth of the population is exponential, so is the consumption of resources. With each generation as the population doubles, the strain on the resources increases. This continues until the resources become depleted and cannot sustain the population numbers. Because resources are always infinite, this is why it is rare to find any population, including bacteria, sustaining exponential growth for long periods. Most common population growth is logistic (S-shaped).

Alexxx [7]

Answer: (c) can undergo self-renewing divisions for the lifetime of a healthy animal.

Explanation:

The adult hematopoietic tissue or adult hematopoietic stem cells can be found in bone marrow of the animal. These cells have the ability to regenerate and renew so that the production of red blood cells remains continuous till death. Hematopoiesis can be defined as the production of cellular components of blood. The adult hematopoietic stem cells are located in the flat bones and ends of the long bones.

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.
