Answer:
25%
Explanation:
If they are both heterozygous, it means they both have a Dd genotype. If you draw out a punnet square Dd x Dd you end up with the following possible genotypes for the puppy:
DD, Dd, Dd, dd
In order for the puppy to be deaf, it must be dd since deafness is recessive, which is 1/4 (25%)
I think the correct answer would be the third option. Cell membranes are present in both plant and animal cells. Both cells are eukaryotic cells so that they both contain membrane-bound organelles like the mitochondria, nucleus, lysosomes and the endoplasmic reticulum. Also, Both cells have the same processes for reproduction including mitosis and meiosis. For plant cells, additional structures can be found namely the chloroplasts, vacuoles and the cell wall. Another difference of the two would be the size. Animal cells are smaller than plant cells. Animal cells would have sizes ranging from 10 to 30 micrometers while the plant cells would be 10 to 100 micrometers.
The best and most correct answer among the choices provided by your question is the first choice or letter A.
The process that describes a possible path of rain through the water cycle is: <span>evaporation, condensation, precipitation, runoff.</span>

The codons that code for alanine in a potato beetle are the same as those that code for alanine in mackerel and humans. This evidence best supports the idea that -(D) different species share components of the genetic code
Explanation:
Evaluating the other options given
A.humans and fish evolved from insects
-This option is incorrect as human and fish did not have a common ancestors.
B.
different species synthesize the same proteins
:No this statement also is not the correct option
C.
insects, fish, and humans express the same genes-The expressed genes cannot be same for different species
Hence the correct answer is
The codons that code for alanine in a potato beetle are the same as those that code for alanine in mackerel and humans. This evidence best supports the idea that -(D) different species share components of the genetic code(As the genetic code is said to be universal
