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

Draw the structure of DNA nucleotide with adenine as nitrogenous base <br>

zavuch27 [327]

Answer:

A nucleotide is made up of one sugar molecule, one phosphate molecule and one of the four bases. Here is the structural formula for the four nucleotides of DNA. Note that the purine bases (adenine and guanine) have a double ring structure while the pyrimidine bases (thymine and cytosine) have only a single ring.

A student is making a diagram of water cycle. What should draw to illustrate evaporation?

nalin [4]

The diagram of water cycle includes the evaporation of water from water bodies. This is often expressed by an arrow or a bunch of arrows that arise from the water body and point towards the sky.

Some diagrams also symbolically show the evaporation process as water vapor that is symbolised with wavy curved arrows

Natasha_Volkova [10]

Answer:

Lactase

Explanation:

Lactaid is a medication that contains the milk protein digesting enzyme Lactase. It is an enzyme supplement for those people who have trouble in digesting milk and other dairy products. Such condition occurs in Crohn's disease and termed as lactose intolerance. Lactase specifically acts on the lactose containing substrates and digests them by enzymatic activity. So people with lactose intolerance can be able to take dairy products with the help of Lactaid.
