A girl of normal stature is born to two parents with achondroplasia who have very short stature, especially disproportionately s
IRINA_888 [86]

Answer:

0%

Explanation:

Achondroplasia is an autosomal dominant disorder that is expressed in both homozygous and heterozygous dominant genotypes. Since two affected parents have a normal girl child, both the parents should be heterozygous carrier for the disease.  Let's assume that the dominant allele "A" is responsible for the disease. Genotype of both the parents of the girl would be "Aa". The genotype of girl with normal stature is "aa". Genotype of her normal partner is "aa".

A cross betwee aa X aa would get all the progeny with "aa" genotype. Therefore, all of their children would have normal stature and there is 0% probability for them to have a child with achondroplasia.

Which type of epithelium is composed of multiple layers, including an apical layer containing tall, slender cells?
Mademuasel [1]

The question is incomplete as it does not have the options which are:

  • Simple squamous
  • Simple columnar
  • Pseudostratified squamous
  • Stratified squamous
  • Stratified columnar

Answer:

Stratified columnar

Explanation:

Epithelial tissue is the tissue formed by the cells which form a layer of cell and lines the lumen of the organ and also covers the organs. The epithelial tissue can be classified based on the number of layer and shape of the cell.

In the given question, the shape of the cell is slender and are tall therefore are called columnar. The cells form more than one layer or multiple layers therefore form stratified layers.

Therefore,  the epithelial tissue formed by these slender shaped multiple layers is known as the stratified columnar layer. The stratified columnar is present in the respiratory tract and the digestive tract.

Thus,  Stratified columnar is the correct answer.

Scientists at the National Oceanic and Atmospheric Administration (NOAA) use mathematical computer-based models to help manage m
kobusy [5.1K]

Answer:

A). The model does not predict energy flow.

Explanation:

As per the given details, the most probable constraint of using 'numerical computer-built models' would be their 'inability to forecast the energy that is flowing throughout the ecosystem.' However, they assist in offering collected information at the same time yet <u>its failure to predict the actual amount of energy flowing that will lead to a failure to predict if the ecological balance is being maintained or not</u>. As a result, some organisms may be deprived of the appropriate food to ensure their survival and their existence on this planet might be under threat. Thus, this is the limitation of using such-technology based models and hence, <u>option A</u> is the correct answer.
