Answer:

catalyze chemical reactions

Explanation:

An enzyme is a proteinous substance that acts as biological catalysts and increases the rate of biochemical reactions in the body. Enzymes are specific in nature which is as a result of the structure/shape of its building block (amino acid).

Enzymes speedens the rate of a chemical reaction in living systems, which would normally not occur or occur at a much slower rate, without the presence of an enzyme. Enzymes acts on the reactants called Substrates by binding to them to form products but they are not used up in the reaction. Hence, enzymes are not reactants.

How many generations does it take for a single bacterial cell to become 256 bacterial cells? (hint, don't forget to count the fi
Tpy6a [65]
Bacteria is a unicellular organism which can multiply very fast by binary cell division.
To get a number of divisions required for cell division: you can use the formula: 2x^{number of generations} = number of bacteria
To get 256 bacteria:
2x^{n} = 256  (you can solve this equation by a calculator)
so:  n = 8 generations

With this formula the first bacteria is taken into consideration since 1 bacteria gives two, then the two give four, then eight, 16...

Suppose a species of bird called the red-crested warbler has a plumage length that is controlled by a single gene. The Plm allel
AleksAgata [21]

We are going to have different allele frequencies for the two populations

North American:

72 birds total => 144 alleles

72 - 55 birds = 17 short plume birds.

q^2 = (2*17) / 114 = 0.236

Freq(short plume allele) = q = 0.486

Freq(long plume allele) = p = 1 - q = 0.514

From this North American population we get

0.486 * 114 = 55 long plume alleles

0.514 * 114 = 59 short plume alleles

South American:

252 birds total => 504 alleles

252 - 75 birds = 177 short plume birds.

q^2 = (2*177) / 504 = 0.702

Freq(short plume allele) = q = 0.838

Freq(long plume allele) = p = 1 - q = 0.162

From this South American population we get

0.162 * 504 = 82 long plume alleles

0.838 * 504 = 422 short plume alleles

Blended population has

55 + 82 = 137 long plume alleles

59 + 422 = 481 short plume alleles

137 + 481 = 618 total alleles

p = 137/618 = 0.222

q = 481/618 = 0.778

The new population has the p and q from the blended population. The new population has 1000 individuals. The portion of long plumed will be homozygote long plumage + heterozygote, which is p^2 + 2pq, and you multiply that by the population size 1000 to get the final answer.

population size * (p^2 + 2pq) = 1000 * (0.222^2 + 2*0.222*0.778) = 395 birds (answer)

According to catastrophists what was the rate of geological change?
givi [52]
Catastrophism is the theory that the Earth has largely been shaped by sudden, short-lived, violent events, possibly worldwide in scope.[1] This is in contrast to uniformitarianism (sometimes described as gradualism), in which slow incremental changes, such as erosion, created all the Earth's geological features. The proponents of uniformitarianism held that the present was the key to the past, and that all geological processes (such as erosion) throughout the past were like those that can be observed now. Since the early disputes, a more inclusive and integrated view of geologic events has developed, in which the scientific consensus accepts that there were some catastrophic events in the geologic past, but these were explicable as extreme examples of natural processes which can occur.

Vera_Pavlovna [14]

Answer:

This happened because the check points in cell cycles are not working properly which can help to stop cells having abnormal chromosomes.

See the attachment for proper understanding what actually happened in cell cycle check points.
