Only one homologous pair enters each daughter cell during meiosis I, which results in a halploid cell. Only sister chromatids are divided during meiosis II. In contrast to mitosis, sister chromatids are not pushed apart at the centromere during meiosis I but are during meiosis II.
What does meiotic nondisjunction entail?Meiosis I (first row), meiosis II (second row), and mitosis are three processes in which nondisjunction can happen (third row). Aneuploids, or daughter cells with unusual chromosomal counts, can result from these unequal separations.
What transpires in meiosis 1?The first stage of meiosis, during which one parent cell divides into two daughter cells, is referred to as meiosis 1. Homologous chromosomal pairs will segregate and separate at this point.

Compared to an adult, the diaphragm dictates the amount of air that a child inspires because the intercostal muscles are not well developed.
What is intercostal muscles?
Intercostal muscles are those found inside the rib cage. The muscles that fill the gap between the ribs are composed of three layers: the outermost, middle, and innermost.
What are the intercostal muscles used for?
The auxiliary respiratory muscles are located within the intercostals. They make forced expiration possible by depressing the ribs, reducing the diameter of the thoracic cavity, and forcing air out of the lungs along with the innermost intercostals.
Where are the intercostal muscles found?
There are two types of these muscles: internal and external intercostals, which are located between the ribs.
The internal intercostal muscles, located inside the ribcase, extend from the front of the ribs and turn around to the back, past the bend in the ribs.

DNA replication is the process through which cells make copies of the genome's DNA.
What is replication?One of DNA's most astounding tricks is likely DNA replication. If you stop to think about it, every cell has all the DNA required to create every other cell.
And from a single cell at the beginning, we eventually have trillions of cells. Additionally, every piece of information present in a cell must be precisely copied during the process of cell division.
Therefore, DNA is a molecule that can be copied to create almost exact duplicates of itself. Considering that there are over three billion base pairs in DNA that need to be copied, this is even more astounding.

what is the clinical significance of bronchopulmonary segments? what is the clinical significance of bronchopulmonary segments? bronchopulmonary segments separate the lungs into the two lobes of the left lung and the three lobes of the right lung. the bronchopulmonary segments allow persons with severe copd to breathe using only the undamaged segments. bronchopulmonary segments divide the thoracic cavity into three separate segments, the central mediastinum and two lateral compartments, which limits the spread of infection. bronchopulmonary segments limit the spread of some diseases within the lungs, because infections do not readily cross the connective tissue partitions between them.
The trachea is divided into two principal bronchi with the aid of bronchopulmonary segments, which have clinical relevance.
Why are bronchopulmonary segments important?Since each segment has an own pulmonary arterial branch, the bronchopulmonary segment is a section of the lung that receives blood from a separate bronchus and artery. Each segment is physically and functionally distinct, enabling a single segment to be surgically removed without having an impact on its surrounding segments.

Answer:
fghthrt
Explanation:
Approximately 4000 years ago, a small number of people settled in areas of Finland and became separated from the rest of the population. These people reproduced, but due to the low number of people, it caused a loss of genetic diversity in the subsequent offspring, which caused many disorders to arise. These disorders are collectively known as Finnish heritage diseases. This event was so significant that even today, one in five Finnish people carry at least one gene related to a Finnish heritage disease. A man and a woman, both of Finnish heritage are aware of this, so they see a genetic counselor. They are interested in having a child but fear they may pass on a disease. They have their DNA analyzed and it comes back that they are both carriers for the recessive disease known as megaloblastic anemia, a type of anemia common in Finnish descent. Thankfully, if they have an affected child, it is treatable. a) What is the probability that, if they have a child, it will have megaloblastic anemia? b) Let’s say they decide to have three children total. What is the probability that all three children would have the disease? c) What is the probability that, if they have three children, none of them will have the disease?
50% is the probability that they have a child will have megaloblastic anemia
What is megaloblastic anemia?
Megaloblastic anemia is a form of macrocytic anemia, a blood disorder that happens when your bone marrow produces stem cells that make abnormally large red blood cells. Megaloblastic anemia is a type of vitamin deficiency anemia that happens when you don't get enough vitamin B12 and/or vitamin B9 (folate).
Moreover, deficiencies of vitamin B12 and folic acid are the leading causes of megaloblastic anemia. Folic acid is present in food such as green vegetables, fruits, meat, and liver.
Hence, the most common causes of megaloblastic anemia are deficiency of either cobalamin (vitamin B12) or folate (vitamin B9). These two vitamins serve as building blocks and are essential for the production of healthy cells such as the precursors to red blood cells.

Genetic variation among humans is relatively small when compared to other species. Where in the human genome does most of the diversity occur?
in the mitochondrial DNA
in single nucleotide-polymorphisms
in sequences that code for tRNA
in the homeotic genes
In single nucleotide polymorphisms.
Why do humans have less genetic diversity than other species?Since all humans have a common ancestor, only a tiny subset of variations varies significantly in frequency between groups. Due to stochastic sampling error, small populations typically lose genetic diversity more quickly than large populations (i.e., genetic drift).
Do humans differ from other species in terms of genetic diversity more or less?When a species' nucleotide diversity is greater than 5%, it is said to be genetically hyperdiverse. Nucleotide diversities in most plants and animals are less than that quantity. Humans, by way of comparison, have a nucleotide diversity of roughly 0.1%, according to Cutter.
