Help please !! I really don’t understand this much☹️
morpeh [17]
Ok, so I wrote these out just to make it a little bit easier for you to understand what I am about to explain.

So for the first one you have two different traits that can be inherited- having freckles or having no freckles, F and f respectively. The dominant trait (or having freckles) is shown by the capital F, and is almost always expressed over the recessive trait, or the lowercase f. So, for example, if you have a genotype of Ff, the trait having freckles will show up instead of not having freckles. The only way that you could have the trait of no freckles show up is if there are two recessive alleles for having no freckles, or ff. In this case, you have two parents who are both heterozygous for the trait of having freckles, so in other words the mother has Ff and the father has Ff. Each parent passes down one allele to the offspring, so since you are breeding Ff and Ff, you should result in having the possible genotypes of FF, Ff, Ff, and ff. This means that there is a 25% chance that the offspring will be homozygous for having freckles, a 50% chance that the offspring will be heterozygous for having freckles and a 25% chance that they would be homozygous for having no freckles, or a 1:2:1 ratio.

Incomplete dominance is a little bit different that just a normal monohybrid cross. Instead of just the dominant gene showing up in a heterozygous genotype, both traits show up. So like the question says, if a homozygous red flower plant was crossed with a homozygous white flower plant, their offspring would not just be white or red, they would be pink because it is a mixture of white and red. So then if you crossed the heterozygous, or Rr plants, the result would be a 25% chance of getting a homozygous RR red plant, a 50% chance of getting a pink Rr plant, and a 25% chance of getting a white rr plant, or another 1:2:1 ratio.

Sorry for the wordy answer, but hopefully this helps you understand this a little better :)

Rna in cells differs from dna in that ___________________. select one:
irinina [24]
Hello! 

RNA in cells differs from DNA in that it is single-stranded and can fold up into a variety of structures.

RNA is the abbreviation for RiboNucleic Acid. It is a biological molecule that fulfills an important role by copying the information stored in the DNA (DeoxyriboNucleic Acid) and transporting it to the different proteins by folding into different shapes. Its name come from a Ribose molecule that is present in this single-stranded molecule.  

Viruses don't have DNA, only RNA. They only replicate in the host's cells by copying their own RNA information. 

Have a nice day!

Which of the following is most easily changed to alter resistance?
Leya [2.2K]

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.
