Answer:
Las enzimas hacen girar al mundo
Esos cambios rara vez ocurren por sí solos cuando observa los sistemas biológicos. ... Para descomponer una proteína en sus aminoácidos, necesitará enzimas. Las enzimas son moléculas biológicas (proteínas) que actúan como catalizadores y ayudan a que se produzcan reacciones complejas en todas partes de la vida.

Answer:
Lysine is important because it is very essential for the body functions of a pig.
Explanation:
Pigs require high levels of lysine, an amino acid. Without enough of this, muscle proteins cannot be formed because amino acids cannot combine correctly. Lysine is essential for body function. Corn diets can only provide pigs with limited lysine and this is not up to what is needed in a pigs nutrition. If the pig is consuming enough lysine then it can use other essential amino acids.
Answer:
6.25%
Explanation:
Given that:
The trait of a female fruit fly that is heterozygous for red eyes = XRXr; &
The trait of a white-eyed male is XrY_ ;
since Y is dominant y; the male trait can either be XrYR or XrYr
So, let assume that it is XrYr
Then; if each trait self crossed; we have:
XRXr = XX Xr XR Rr
XrYr = XY Xr rY rr
Thus, the punnet Square can be computed as:
XX Xr XR Rr
XY XXXY XXYr XXYR XRYr
Xr XXXr XXrr XXRr XRrr
rY XrYX XxYr XrYR RrYr
rr XrXr Xrrr XrRr Rrrr
∴
the percentage of offspring that would have white eyes XrY_ is:
1/16 = 0.0625
= 6.25%
<span>Chromosomes can increase genetic diversity by the way they are replicated. Since chromosomes are paired, and sperm and egg cells have only 1 of each pair, few sperm and egg cell wil have identical chromosomes. For humans, with 23 chromosome pairs, the number of possible combination of chromosomes for any child is over 8 million. That means the chance of any 2 siblings (who are not identical twins) having the same chromosomes from both parents is less than 1 in 8 million. Add to that the possibility of chromosomal crossover during the production of sperm or egg cells, and the number of different gene combinations in any child becomes staggering. If a frog, for example, lays a few thousand eggs, chances are that all of them will have different chromosomes within their cells. That may be why natural selection has favored organisms with dozens of pairs of chromosomes. Organisms with lots of chromosomes can maintain a high level of diversity within the population. Since genetically diverse species are more resistant to disease, it is not difficult to understand many different lineages have converged upon the same solution of having dozens of chromosomes.</span>
