Neurofibromatosis type 1, also know as NF1 is a genetic disorder that is caused by gene changes (also called mutations). The NF1 Gene is found on chromosome 17 and it carries the instructions to create a protein called NF! NF1 regulates mitosis, and works to prevent cells from growing and dividing in an uncontrolled way. The cells of individuals with NF1 divide out of control, leading to the creation of tumor. We have found that Kai has one mutation that was detected in the NF1 gene.
Kai may have NF1 Because of the parents may be a carrier The genes we inherit compose our genotype and determine the physical characteristics we possess, our phenotype. Alleles are important for the variations in which the trait can be expressed. The stronger allele is known as the dominant gene, and the weaker allele is known as the recessive gene. A phenotype is an individual's observable traits, such as height, eye color, and blood type.
The genetic contribution to the phenotype is called the genotype. The gene changes can be passed from parent to child, or they can happen on their own. If you have NF1 or NF2, your baby has a 50-percent chance (1 in 2) of inheriting it from you. heterozygous are carriers in recessive genetic disorders a person with recessive alleles but does not display trait, can pass the trait.
When there is two identical alleles of a particular gene that is h.o.m.ozygous and if there is two different alleles of a particular gene or genes, then that is heterozygous.
Neurofibromatosis kind 1, additionally recognise as NF1 is a genetic disease this is due to gene adjustments (additionally referred to as mutations).
The NF1 gene is discovered on chromosome 17 and it includes the commands to create a protein referred to as NF1 regulates mitosis, and works to save you cells from developing and dividing in an out of control way. The cells of people with NF1 divide out of control, main to the advent of tumor. We have discovered that Kai has one mutation that changed into detected withinside the NF1 gene.Kai can also additionally have NF1 Because of the mother and father can be a provider the genes we inherit compose our genotype and decide the bodily traits we possess, our phenotype. What is genetic contribution?The genetic contribution to the phenotype is referred to as the genotype. The gene adjustments may be exceeded from determine to child, or they could occur on their own.

Why is the countercurrent system of flow important for fishes?
Question: Why is the countercurrent system of flow important for fishes?
Explanation and answer: Fishes use a design called 'countercurrent oxygen exchange' to maximize the amount of oxygen that their blood can pick up. They achieve this by maximizing the amount of time their blood is exposed to water that has a higher oxygen level, even as the blood takes on more oxygen.

E) Diabetes had the greatest rise in prevalence in 1997 until 2000, with prevalence percentages between about 76% to 78%.
Explanation: Explanation for these answers are below:
D) Looking at the graph, obesity and diabetes had similar prevalences in 1997 and 1998, and started to part ways a little in 1999. In fact, even without the graph, scientists have known for a long time that people who have obesity also have diabetes. This graph supports that claim because of how closely linked diabetes and obesity are and how similar the prevalence percentages are.
E) Diabetes had the greatest rise in 1997 to 2000, which had a 78% prevalence by 2000. Obesity had very similar prevalence percentages from 75.5% to 77% in 1997 to 2000.

What happens when carbon dioxide from the atmosphere dissolves in seawater.
Answer:
When carbon dioxide dissolves in seawater, most of it becomes bicarbonate ions and hydrogen ions. This increase in hydrogen ions is what decreases the pH. In addition, some of the hydrogen combines with carbonate to form more bicarbonate, decreasing the concentration of carbonate in seawater.
When carbon dioxide dissolves in seawater, most of it becomes bicarbonate ions and hydrogen ions. This increase in hydrogen ions is what decreases the pH.
When carbon dioxide dissolves from the air into the ocean?The ocean takes up carbon dioxide through photosynthesis by plant-like organisms carbon dioxide dissolves in water. It reacts with seawater, creating carbonic acid.

How does natural selection enable species to changes their body shape, appearance, and/or size over time? *
A) Individuals that are better adapted to their environment survive and reproduce.
B) Overproduction provides food for stronger members of the species.
C) Environmental changes kill weaker members of the species.
Answer:
A
Selective pressures( Predators, less food etc. ) will cause the less fit variation of a species to decrease in population, causing them not to be able to reproduce. The more fit variation would be able to reproduce more so that over time, the individuals in the species will have the features of the more fit variation.
