Answer:

Please see below  

Explanation:

The supporting data has been organized in a table and attached as an image herein. As can be clearly seen from the data table, the zones under study are nothing alike. The home area is mostly for residential use and gives the greatest percentage for being used for housing purposes. However, the Mount Pinatubo area is mostly being for vegetation.

A couple planning their family are aware that through the past three generations on the husband's side a substantial number of s
Nesterboy [21]

Answer:

a) There are lots of genes on chromosome 1 could be affected, and the gametes could be imbalanced (missing segments of DNA or whole chromosomes)

b) Roughly 50%

c) No. I would advise that the couple undergo preimplantation genetic diagnosis, so that a zygote carrying the normal copy of chromosome 1 could be selected.

Explanation:

Chromosome 1 is one of the largest and most gene rich chromosomes. An inversion that covers 70% of its length would cover lots of genes.

While an inversion on its own would not seem problematic (as all the genes on the chromosome are still there), when it comes to meiosis, the sister chromatids would not be able to correctly align, and crossing over would further complicate this. It could also lead to unbalanced gametes missing entire parts of the chromosome. Therefore, there are likely numerous genes that will be affected and messed up by the inversion.

This could explain the high incidence of past still births, as if lots of genes are affected, and non-functional, the pregnancy would be rendered non-viable, or highly deleterious causing premature death.

b) There is a 50% chance of a child inheriting the defective copy of chromosome 1 (and 50% of a chance of them inheriting the normal chromosome 1. Therefore, there is likely a 50% chance that future offspring would be affected by defects

c) No. I would advise that the couple undergo preimplantation genetic diagnosis. In this, the couple undergoes in vitro fertilization (IVF). When embryos are produced through IVF, they can then be tested for the presence of the abnormal chromosome. Embryos will only be implanted into the mother if the normal chromosome 1 is present.

Which of these statements best sums up evolution?
Ksenya-84 [330]

Evolution can be defined as the process of the change occurring in a population over a period of time through genetic variation. This genetic variation and the process of natural selection help a species to evolve by selecting the traits that helps it to better adapt to the environment. These genetic variations are inherited over time as the species continue to evolve.

Hence, the correct answer is 'change in population through genetic variation over time'.

What is the name of the process of DNA formation from DNA?. A:transcription. B:translation. C:transduction
forsale [732]

The answer is Transcription.

Transcription is the first step to gene expression. This process happens when a certain part of the DNA is being copied into RNA. This process allows the DNA to at least transfer at least one gene to the RNA

What are the values of a, b, and c in the quadratic equation 0 = 5x – 4x2 – 2? a = 5, b = 4, c = 2 a = 5, b = –4, c = –2 a = –4,
12345 [234]

Hey there! :)

Answer:

The 3rd choice. a = -4, b = 5, c = -2.

Explanation:

Rearrange the quadratic equation given into the form 0 = ax² + bx + c:

0 = 5x - 4x² - 2 --> 0 = -4x² + 5x - 2

The corresponding coefficients for the a, b and c values are:

a = -4

b = 5

c = -2.

¿Que celula está compuesta por tres partes importantes que son la membrana celular, el citoplasma y el núcleo celula?
aleksandrvk [35]

Answer:

Células eucarióticas

Explanation:

  • Todas las células poseen membrana celular, encargada de la protección de la célula de agentes externos a ella, y del intercambio de sustancias entre el interior y el exterior celular, entre otras funciones.
  • El interior de la célula eucariótica tiene un citoplasma con organelas y citoesqueleto. Las organelas tambien estan rodeadas por membranas y cumplen diversas fnciones cada una, que se acoplan para el correcto funcionamiento de la célula.
  • Finalmente, a diferencia de las céllas procariotas, las eucariotas tienen un núcleo que protege el material genético de la célula. En núcleo tiene una doble membrana que lo separa del citoplasma.
