A mistake in DNA replication, in which the wrong base is placed in the growing DNA strand, can have profound effects on the desc
Klio2033 [76]

Answer:

DNA replication is the process in which the DNA is copied and it occurs during synthesis phase of the eukaryotic cell cycle. It begins with an enzyme breaking the bonds between complementary bases in DNA which exposes the bases inside  the molecules so they can be read by another enzyme and used to build two new DNA strands with complementary bases.

Explanation:

The original strand is: TAGCGTT

                                      ATCGCAA

The Mutated strand is: TGGCGTT

                                       ATCGCAA

<em>The replicated strand is: GAATCAC</em>

<em>                                           CTTAGTG</em>

The image shows the evolution of a species of fish. A few fish from a population developed different social behaviors and evolve
adell [148]

According to the image, the fish underwent sympatric speciation. The new species of fish had mating seasons that were different from that of the original fish. Because of the differences in mating seasons, the fish underwent reproductive isolation. This mode of isolation would be temporal.

Sympatric speciation happens within a population of an organism that gets isolated reproductively due to differences in their mating periods. This time dependent isolation is called temporal isolation. Example, a fish population can split into two if some of the fishes start mating early in the spring while the rest mate late in the autumn. The spring-mating population will not become compatible to mate with the late-autumn-mating population.

The nutrients which serve as the main sources of energy for the body are
puteri [66]
Complex carbohydrates Such as insoluble fiber. Your body will break that down first because I is much faster than other source to convert to energy. If there isn't any carbs available your body will then convert fat into energy and lastly if there is t and carbs or fat your body will then breakdown protien into energy but that is truly the last resort. Sorry for the errors in this texts I was writing very fast and my phone will not allow me to edit.

muminat

Answer:

Because genetic drift (Founder effect) is acting on this population. Not all the Hardy weinberg criteria are accomplished. There are no random matings and populations are finite-sized.

Explanation:

This is a special case of genetic drift: the founder effect.

The “Founder effect” phenomenon refers to cases where a new population originates from a few founder individuals, coming from a bigger ancestral population, that established in a new environment. This small population might or might not be genetically representative of the original one. This subgroup carries with them some genetic information that they share with their original population. Over time, some genes can be lost, or they can increase in frequency. Some rare alleles might be exceeded or might be completely lost. On Consequence, when the small population grows, it will have a genetically different composition from the original one. In these situations, genetic variability is reduced and enhances the possibility of developing a peculiar allelic composition. In some cases, the founder effect is part of the process of speciation.  

The criteria for maintaining a Hardy-Weinberg equilibrium are:  

  • Random matings
  • No superposed generations
  • No mutations
  • No migration  
  • Infinite population size
  • No natural selection

Genetic drift involved the un-accomplishment of random matings and infinite population sizes.

Genetic drift involves:

  • limited population sizes
  • individuals reproduce by endogamy/exogamy, and matings occur by phenotype.
