Answer:

The result will be two gametes with a normal haploid number (n), one gamete containing an extra chromosome (n + 1) and one gamete missing one chromosome (n − 1).

Explanation:

Nondisjunction is caused by the failure in the mechanism of separation of homologous chromosomes or sister chromatids during meiosis and/or mitosis. The failure in the separation of sister chromatids during meiosis II is referred to as 'secondary nondisjunction' and it produces two daughter cells with abnormal chromosome numbers.  

The fusion of one gamete containing an extra chromosome (n + 1) with a normal (n) gamete will lead to trisomy (2n + 1), while the fusion of one gamete missing one chromosome (n - 1) with a normal gamete will lead to monosomy (2n-1).

mart [117]

The idea of evolution is that the species change over time. The proposed mechanism of evolution is natural selection. Natural selection favors inheritable traits, suitable (adapted) for survival and reproduction. Organisms with such traits will tend to leave more offspring than others, and thus will evolve over time.

Some of the people that influenced Darwin are:

• Lamarck who first proposed  that humans evolved from a lower species through adaptations over time

• Malthus, economist who explained that population grows faster than food production could sustain. So, Darwin proposed that only individuals that have favorable adaptations would survive.

How does joining a flock most likely increase an individual bird's chance of survival
ioda
Here are the reason why joining flocks will increase their chance of survival:

- Protection from predator
Their predator (such as falcons) can only get one bird at a time. Joining a flock will reduce their chance of being caught because they are moving in large unstoppable mass.

- Conserving heat
Being around the flock will help them maintain their body temperature to survive a harsh winter.

A body buried will completely skeletalize faster than one left on the surface of the ground
N76 [4]
The statement "<span>A body buried will completely skeletalize faster than one left on the surface of the ground" is FALSE.  It is said that a body placed above the surface of the ground could decompose for about eight months until it becomes skeletalize, compared to a body being buried below the ground.</span>
