Natural selection is a theory that states that those individuals who are best adapted to live in an area will survive and reproduce. Within a given population, there exists a normal degree of genetic variation that may or may not make an individual more adapted to the environment or, more importantly, changes in the environment. A species with a great deal of genetic variability is more likely to survive as a species in a changing environment than a species with limited variability.

A cross between a red flower and a white flower produces red and white spotted flowers. Which type of inheritance pattern is ind

Nutka1998 [239]

The correct answer is codominance.

Codominance is when the alleles of a gene, in a heterozygote organism, are not fully expressed. In this case, either red or white fully dominates but they still manifest that they are present in the flower.
Do not get confused with incomplete dominance because that would result in a pink flower.

Compare the costs and benefits of hydro power to that of geothermal power. (Please include two costs and two benefits.)

EleoNora [17]

Hydroelectric Power
The benefits are: 
1. Hydroelectric power is mainly a renewable source of energy. It relies on the stream cycle of water which do not cause pollution.
2. Hydroelectric power also helps and promote water reservoir and storage.

The cost are:
1. 0.85 cents per kWh is the average cost in the US.
2. Conventional installation costs $1,000-$5,000

Geothermal Power
The benefits are: 
1. There is no pollution
2. We lessen the utilization of fossil fuels

The costs are: 
1. $0.03 to $0.035 per kWh is the cost of electricity by The Geysers.
2. $20,000 to $25,000 costs to build this power plant

Hope this helps.
