The controlled process by which hydrocarbons are broken down or re-arranged into smaller, more useful molecules is called Cracking. The process allows large hydrocarbon molecules to be broken down into smaller, more useful hydrocarbon molecules. Cracking may be done using heat energy (thermal cracking) or using a catalyst (catalytic cracking). Fractions containing large hydrocarbon molecules are vaporized and passed over a hot catalyst, thus breaking chemical bonds in the molecules and forms smaller hydrocarbon molecules.

The information in the table shows the possible genotypes resulting from the mating of two heterozygotes aadd. the allele a code

tensa zangetsu [6.8K]

Admitting that the "a" is a capital A for normal pigmentation and "d" is a capital D for dimpled chin, meaning that these are the dominant traits, the fraction expected to be albino with a non-dimpled chin is of 1/16.
When two heterozygous are crossed and two characteristics are being analysed, the offspring quantity that will possess the two recessive traits can be represented by 1/16. This is easily confirmed when a Punnett square is made. Considering that both parents were heterozygous, on both sides of the crossing in the Punnett square, you would have the following alleles' combination: AD, Ad, aD, and ad. The offspring that would be homozygous recessive (aadd) would correspond to only 1/16.

How does antibiotic resistance arise? how do hospitals and feedlots contribute to this phenomenon?

Stella [2.4K]

<span>Antibiotic resistance arises due to the evolution of the organisms they are designed to destroy. Subsequent generations of such organisms develop resistance to the antibiotic. Hospitals' overuse of antibiotics quickens the process, as does the administration of antibiotics to feedlot cattle, whose meat is consumed by people.</span>

Human bodies contain enzymes that can break down starch into glucose and use it for fuel. We do not have the enzymes necessary to breakdown cellulose.
