The phenotype is purple(the physical appearance)

None of the flowers will be red

All will be purple.

None will be blue

Note: the crossing above indicates a case of co-dominance

Novay_Z [31]

Answer: Most viruses can use host machinery to produce more of themselves

Explanation:

Since viruses carry out no metabolism themselves, they rely solely on the living cells of the host (organism they infect) to replicate and spread from cell to cell.

Thus, viruses do not kill the cells they infect since they need them, and use them to replicate more offsprings

Why do multiple and lethal alleles often result in modifications of the classic Mendelian monohybrid and dihybrid ratios?
allochka39001 [22]

Answer:

Multiple alleles can modify the classical Mendelian ratio by increasing the number of phenotypes.  

For example, in a monohybrid cross, Mendel gets only 2 phenotypes however, in ABO blood groups (a classical example of multiple alleles) there are four phenotypes present in a population.

Lethal alleles are the alleles which when expressed result in the death of an organism. These alleles can be dominant, recessive or conditional (depends on interaction with another gene).  

Thus, lethal allele reduces the ratio of the phenotype associated with it by affecting the survival of the organism.

For example, lethal yellow allele in mice results changes the phenotype ratio from 3:1 to 2:1

Natalka [10]
This varieation can be justified because since they had different variations they probably had different niches which led them to evolve differently,this will help because the two species will have no competition

If the body temperature of a person is recorded as 37 degrees Celsius, what is the persons body temperature in k? Round your ans
maw [93]

Answer:

The right answer to this question is: 310k

Explanation:

There's a very good formula that can help us to find this answer, but first, we need to know the temperature scale  in Celsius and Kelvin, there's an image below that will help us gather information.

The formula is quite simple, check it below:

C/5  = K-273/5

putting the values we already have in the formula it would be like this:

37/5 = K-273/5

Cutting out the fives, we can have the final result

37= K-273

37+273 = K

K= 310.
