<span>Here are some advantages:
1. it can create new varieties of good crops.
2. it allows for higher profit.
3. it does not have a issue of safety.
4. it helps eliminate diseases
5. it can produce fitter and stronger animals
Here are some disadvantages:
1. it can lead to a loss of species variety
2. it doesn't have control over genetic mutations
3. it brings discomfort to animals
4. it can create offspring with different traits
5. it poses some environmental risks</span>
Answer:
The sample mean is obviously different from the population mean, but tests of significance must be done to determine if the difference is statistically significant. The difference could possibly be attributed to chance or to sampling error.

Answer:
Now i know that natural resources are important because they are used to make our food and fuel. all of the food we eat comes from plants and animals and if we didnt have plants or animals we wouldnt exist right now. natural resources are important also because they make our fuel and they provide heat, light, and power. they are the main thing we need to survive. we have to protect and conserve natural resources!
Explanation:
Answer:
Answer is C.
Explanation:
A. The vessel length is pretty much constant. The body can't length or shorten blood vessels.
B. Blood viscosity is also fairly constant because the composition of blood cannot change quickly enough to change resistance as needed.
C. This is the main way resistance is controlled. The smooth muscle surrounding blood vessels can rapidly respond to hormonal or metabolic stimuli and contract/relax to adjust diameter.
D. Again, temperature is fairly constant in the body and would not be a good way to alter resistance.
Monohybrid crosses only look at one genotype. Whereas dihybrid crosses look at two genotypes.
An example of a monohybrid cross would be AA x aa, where A represents the dominant allele, and its phenotype is the colour red, and a represents the recessive allele, and its phenotype is the colour white.
An example of a dihybrid cross would be SSYY x SsYy, where the letter S represents the size, dominant phenotype is large, recessive is small, and Y represents the colour, dominant phenotype is yellow, recessive is green.
