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!

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.
QUESTION: If Deborah marries a man unaffected by Cystic Fibrosis, which of the following describes the possibility that her daughter will be affected by Cystic Fibrosis?

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.

What composes a photosystem?
The "special chlorophyll" molecules in the reaction center are what the photosystem will use to absorb all of the sun's energy.
What is a photosystem?A core complex and a periphery antenna system referred to as the light-harvesting complex I (LHCI) for PSI and the light-harvesting complex II (LHCII) for PSII, respectively, make up each photosystem.
Light-harvesting structures and reaction hubs make up photosystems. To two unique chlorophyll molecules in the reaction center, pigments in the light-harvesting complex transfer light energy.
Sunlight is captured in the chloroplast by pigment chlorophyll molecules arranged into photosystems.
Therefore, the light-harvesting complex, which consists of pigments, and the reaction center make up the photosystem.

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.

Identify the type of mutation that occurred and explain in what way it affected the protien
Answer:
The type of mutation that occurs when in the DNA strand there is a change from guanine to cytosine is a nonsense mutation, since the triplet that should encode the amino acid encodes a stop codon and the protein cannot be completely synthesized.
Explanation:
The nonsense mutation consists of a change in one of the bases of the stranded DNA, which is transcribed into an altered mRNA, producing a stop codon, instead of an amino acid.
In the table it is observed that the CCA codon is a stop codon that cuts off the protein synthesis prematurely, leaving it incomplete and probably non-functional.
Sometimes this type of mutation can alter the sequence of amino acids but the protein may be complete enough to partially fulfill its function.

Explanation:
The top of the saturated zone is known as A. the aquifer B. the water table C. the unsaturated zone D. spring rock
Answer:
B. the water table
Explanation:
The question above is related to the topic on "Groundwater."
Groundwater is considered "fresh." It falls into the soil and gets soaked in it. It can stay stored for many years. It is very beneficial because it serves as a source of water for many residential places.
The storage of groundwater relies on two zones: unsaturated zone and saturated zone. The unsaturated zone is the first layer under the surface area of the land. It is followed by the "water table," which lies a little farther from the land surface. After which is the saturated zone where you can find particles of different rocks.
The top of the saturated zone is known as the water table. Therefore, option (B) is correct.
The water table divides the saturated zone, where water fills the crevices between soil or rock particles, from the unsaturated zone, which is air-filled. Precipitation, groundwater exploitation, and seasonality affect the water table. It controls groundwater supply and flow.
Spring or surface water bodies can form where the water table meets the land. Managing water supplies, analysing groundwater flow patterns, and assessing groundwater contamination require water table monitoring.

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.
