Answer:
Yeast does not produce lactase and therefore cannot digest lactose
Explanation:
Yeast does, however, digest glucose very efficiently. When it digests glucose, the yeast breaks down the glucose and produces carbon dioxide gas as a waste product
These gases<span> may have consisted of hydrogen (H2), water vapor, methane (CH4) , and carbon oxides.

Answer:
If twins are a boy and a girl, clearly they are fraternal twins, as they do not have the same DNA. A boy has XY chromosomes and a girl has XX chromosomes. Girl-boy twins occur when one X egg is fertilized with an X sperm, and a Y sperm fertilizes the other X egg.
Explanation:
Answer:
The correct answer is "In order to create a synthetic life form it would be necessary to know the function of every gene and include them in the organism".
Explanation:
The most common approach of studies using recombinant DNA technology is to insert a desirable gene from one organism into a host organism. This approach is much more feasible that creating a synthetic life form because, in order to create a synthetic life form, it would be necessary to know the function of every gene and include them in the organism. Even though the whole DNA sequence of many organisms is known (including humans), the function of the entire sequences of the genome is yet to be understood.
The
two categories that are used to classify physical changes are Reversible and
Irreversible.
Reversible
means that the matter can convert to gas, liquid and solid and then convert
back to gas, liquid or solid. So it means it can convert back and forth.
<span>Irreversible
means that matter cannot be converted back as it is before.</span>
