Answer:

Enzymes are biological catalysts. Catalysts lower the activation energy for reactions. The lower the activation energy for a reaction, the faster the rate. Thus enzymes speed up reactions by lowering activation energy.

An enzyme is a form of biological catalyst. This means that as the enzymes breaks down the detritus within the cells, this speeds up the chemical reactions within.

Indicate the coat color and the proportion of offspring with that color for each of the following crosses of rabbits. Assume all
PolarNik [594]

Answer:

C) all chinchilla

Explanation:

As we know that dominance of alleles for the coat color in rabbits goes like this:

                                          C+ > Cch > Ch > C.

  • The allele for full colour or agouti is  designated as C+.
  • Allele for mutant coat color  silvery- gray coat-chinchilla is Cch.
  • Allele for “Himalayan” coat is called ‘Ch
  • Albino rabbits have whole white coat and allele for this is c

If we cross homozygous chinchilla with homozygous chinchilla the cross will look like this:

P1:                                            chinchilla x chinchilla

P1:                                             Cch Cch    X   Cch Cch

F1:                                          Cch Cch       :       Cch Cch

Since all offspring have Cch Cchgenotype that is foe chinchilla phenotype  it means that all the offspring will have chinchilla phenotype that makes option C correct.

Hope it help

Most carbohydrates (sugars and starches) are converted into glucose before they are broken down in the cytosol to release energy. ... If oxygen is present, then glucose can be broken all the way down into carbon dioxide and water.
