The modern theory of evolution states that a basis for variation within a species is provided by mutations.  It plays an important role in evolution. The best source of all genetic variation is mutation. It is important as the first step of evolution<span> because it creates a new DNA sequence for a particular gene, creating a new allele.</span>

Inessa05 [86]

Answer:

After constructing a prototype of the device, the student concludes that in many regions the monetary cost of building and installing the  device would be higher than the cost of acquiring water from other sources. Which of the following would be most appropriate for the  student to do next?

redesign the device without the solar panel so that it plugs into an electrical outlet

Explanation:

Because of cost implication, the device is redesigned in order to use other source rather than water which would be cost-effective and generally accepted for use.

Why do you suppose the united states still uses the english system for everyday measurements while almost every other country us
Alchen [17]
Answer:
Because the English measurement system has been in use for a very long time, it will be costly and time consuming to change from the English to SI units. Many technological measurements, products, and tools were developed in English units.

The cost of converting all measurements to SI units will be costly and will require a long period of time. Conversions between the English and the SI system of units appear to be more cost-effective than hardware changes.

Example:
It will be costly to convert designs for bridges, tunnels, locomotives, automobiles, and other hardware to the SI system. Although new designs are being performed in SI units, much useful hardware based on English units still remain.

Eventually, it is likely that complete conversion from English to SI units will happen, albeit slowly.

Use the probability method to calculate the genotypes and genotypic proportions of a cross between AABBCc and Aabbcc parents.
lora16 [44]

For this, you need to use Punnett squares.

You know the genotype of the parents, and for the cross, you need to separate into two alleles, both genes.

AABBCc divided like ABC and ABc.

Aabbcc divided like Abc and abc.

Now you can cross them, and all probabilities will be:

AABbCc, AaBbCc, AABbcc and AaBbcc

So, you could say 25% of the offspring will be AaBbCc, 25% AaBbcc, 25% AABbCc, and 25% AABbcc
