In the spotted tulip, white flowers are dominant to yellow (gene Y), and axial flowers are dominant terminal flowers (gene T). E

aleksklad [387]

Answer:

9/16 A_B_ White colour, axial flower

3/16 A_bb White colour, terminal flower

3/16 aaB_ Yellow colour, axial flower

1/16 aabb Yellow colour, terminal flower

Explanation:

Let the flower colour allele be represented by A and the flower position by B. The dominant white colour would be A while the alternate version (the yellow colour) would be a. Also, the dominant axial flower position would be B while the alternate terminal position would be b.

Given the names of these three enzymes proteases, DNase, RNase what reaction do you expect each one to catalyze

kramer

Answer:

As the name suggests, proteases will be the enzymes which will catalyze the reactions of proteolysis. Proteolysis can be described as the process of breaking proteins into amino acids and simple peptide bonds.

DNases will catalyze the reactions for breaking down or degrading DNA. The DNase does this by breaking the phosphodiester bonds present in the backbone of the DNA.

RNases will be the enzymes which will catalyze the breaking of RNA molecules.

Time on earth is divided into 6 eras. Three are considered "Precambrian" Which eras are NOT Precambrian?

bulgar [2K]

Explanation:

the Paleozoic Era

The Precambrian era describes a period of time that pre-dates Cambrian. This time typically references the entire period of the history of earth before the formation of rocks containing identifiable fossils occurred. It covers the majority of Earth’s history and is divided into the Hadean, Archean and the Proterozoic era.

Just before the Cambrian eruption, in the Paleozoic Era the environment was oxygenated, culminating in an explosion of new life in the Proteozoic Eon (2500-541 million years ago) in the form of primitive blue-green algae named cyanobacteria and oxygen based species. Multicellular species followed later, along with structure at higher levels, and complex life. Oxygen levels grew gradually over this period of time, from low levels.
