Deborah has Cystic Fibrosis, a serious genetic defect that interferes with the body's ability to transfer salt and water to and from the body. The defect causes secretions in her body to be thick instead of the normal thin secretions in healthy people. These secretions clog her passageways which can be life-threatening. The following pedigree shows her family in which some individuals are affected by Cystic Fibrosis.

Explanation:
Why does water have "surface tension"?
Answer:
Hello!
Explanation:
Surface tension in water owes to the fact that water molecules attract one another, as each molecule forms a bond with the ones in its vicinity. ... This inward net force causes the molecules on the surface to contract and to resist being stretched or broken. Hope this helps!
why the answer is C not D?
Answer:
Diffusion describes the movement of particles from an area of higher to lower concentration. That is what the ink is doing when it spreads throughout the jelly. Osmosis only occurs across a semipermeable membrane.
Answer:
osmosis is movement of particles through a semipermeable membrane from the region of high concentration to region of low concentration while diffusion is the movement of particles from a region of higher concentration to a region of lower concentration.
Explanation:
here there is no semipermeable membrane hence the correct answer is diffusion.
Which statement best describes what happens during translation?
Answer:
B
Explanation:
The entire process is called gene expression. In translation, messenger RNA (mRNA) is decoded in a ribosome, outside the nucleus, to produce a specific amino acid chain, or polypeptide. The polypeptide later folds into an active protein and performs its functions in the cell.
During translation, the ribosome reads the mRNA and uses the information to assemble a protein.
Translation is the second step of protein synthesis. It takes place in the ribosome, a complex structure made up of proteins and RNA. The ribosome reads the mRNA, a molecule that contains the genetic information for a protein. The mRNA is translated into a protein by a process called codon-anticodon pairing.
Codons are three-base sequences in mRNA that code for specific amino acids. Anticodons are complementary sequences in tRNA molecules that bind to specific codons. When the ribosome encounters a codon in the mRNA, it brings in the corresponding tRNA molecule. The tRNA molecule carries the amino acid that corresponds to the codon.
The amino acid is then added to the growing polypeptide chain. The ribosome continues to move down the mRNA, reading codons and adding amino acids until the entire protein is synthesized.

Why do different individuals of the same species have different traits?
OA. Individuals have differences in their genes that result in protein variations.
OB. Individuals have proteins that produce genes with completely different functions from other individuals.
OC. Individuals have different proteins that cause variations among their genes.
OD. Individuals have different genes that produce proteins with completely different functions from other individuals.
answer : a
explanation : a species shares ALMOST all of the DNA with each other with just small differences
Different individuals of the same species have different traits because individuals have differences in their genes that result in protein variation. Hence, option A is correct regarding variation.
Why do individuals of different species exhibit different characteristics?
The species is a group of individuals that can reproduce among themselves and can produce fertile offspring. Individuals of a species have genetic variation among them as they are formed by the process of meiosis.
In meiosis, genes cross over and recombination takes place, resulting in the formation of offspring that show some variation from their parents. These characters or traits are encoded in the gene. When these are expressed in the process of translation, the variation is seen.
This genetic variation doesn't make them reproductively isolated. Example: In humans, there are variations based upon the skin color, face size, height, etc. The variation is seen in genes among individuals but not genes are different.
Hence, different individuals of the same species have different traits because individuals have differences in their genes that result in protein variation. Hence, option A is correct regarding variation.

What is the main function of the small intestine?(use terms : villi, surface area,blood capillaries,why must large molecules be broken down, high concentration and low concentration.)
Answer:
Among the principal functions of the small intestine, we might mention the peristaltic movement, secretion through special glandules, digestive function, absorptive functions, secretion functions, and endocrine functions.
Explanation:
The whole digestive tube is approximately eleven meters long, from the mouth to the anus.
The small or thin intestine is the longest organ of the digestive tube. It can reach up to 7 meters long, up to 3 centimeters in diameter, and it characterizes by being folded. These folds are called villi, they project into the intestine light, and they are more concentrated in the first portion of the intestine, the duodene, decreasing to the final region of the organ.
Among the principal functions of the small intestine, we might mention the peristaltic movement, secretion through special glandules, digestive function, absorptive functions, secretion functions, and endocrine functions.
The small intestine receives food from the stomach, and through peristaltic movements, it mixes and carries the material to different regions in the organ. The complex polymeric molecules are digested and transformed into simpler substances. The duodene receives secretions from intestinal glands such as bile and pancreatic juices and mixes them with digestive juices of its production. All of these secretions carry huge amounts of enzymes that will degrade food and transform it into soluble substances, such as amino acids. The intestine walls are covered by villi that increase the absorption surface area. Nutrients are absorbed by primary cells and transported to the bloodstream. Calciform cells secrete mucus to protect the epithelium during digestion. Villi also transport water from the blood to the intestinal tract, which helps in food decomposition. Enteroendocrine cells secrete hormones to the blood vessels and capillaries that enter each villus. When nutrients are small enough they go to enter the bloodstream.
Peyer's patches are nodules or cumulus of lymphatic tissue and other accessory cells, located under the mucosa of the gastrointestinal tract, specifically in the lamina propria of the thin intestine, in the jejunum region. These patches represent the mucosa´s immunity system. In the jejunum, these follicles are isolated from each other in the intestine and low concentrated. But in the terminal ileum (The last portion of the thin intestine) they get so close that they might form a plaque.

If a strand of DNA has 45% A, what percent will be C?
Answer:
55%
Explanation:
Answer:
[tex]\boxed {\boxed {\sf C=5\%}}[/tex]
Explanation:
There is a method to calculating base percentages known as Chargaff's Rule. It states:
[tex]A+T+G+C=100\%[/tex]
We know the DNA has 45% Adenine or A.
Adenine always pairs equally with Thymine. In other words, the percentage of adenine equals the percentage of thymine (45% Thymine or T).
[tex]45\%+45\%+C+G=100\%[/tex]
[tex]90\%+C+G=100\%[/tex]
Subtract 90% from both sides.
[tex]90\%-90\%+C+G=100\%-90\%[/tex]
[tex]C+G=10\%[/tex]
Cytosine(C) and Guanine(G) pair equally and their percentages will be equal. We can divide 10% by 2.
[tex]C+G=10\% /2[/tex]
[tex]C/G=5\%[/tex]
The percentage of Cytosine or C is 5 percent.
