Which cell has the GREATEST surface area to volume ratio?
O Chicken egg
O Skin cell
O Bacterial cell
O Liver cell
The cell with the greatest surface area to volume ratio is the smallest cell, in this case, the bacterial cell.
As a cell increases in size, the proportional increase in volume is higher than that of its surface area. This tells us that the bigger a cell becomes, the lower its surface area to volume ratio will be.
The chicken egg is just one large cell, the largest cell produced by most animals. The skin and liver cells are much smaller, measuring roughly 25-30 micrometers. However, the smallest of the list by far is the bacterial cell, measuring a mere 1-3 microns. This size tells us that the greatest surface area to volume ratio belongs to the bacterial cell.

What term describes the strings of ribosomes that are attached to an RNA transcript at one time?
A. release factors
B. spliceosomes
C. transcription factors
D. mutagens
E. polyribosomes
Answer:
Polyribosomes.
Explanation:
During translation, the subunits of a ribosome surround the transcript and read down stream until they reach the start codon and begin polypeptide synthesis. Once the start codon is exposed, it is available for another ribosome to form around it, thereby initiating another locale for translation. Together the strings of ribosomes are called polyribosomes.

The mechanism by which plants convert carbon dioxide, water, and sunshine into oxygen and sugar-based energy is known as Photosynthesis.
What steps are involved in a plant's photosynthesis?Green plants and various other organisms convert light into chemical energy through a process called photosynthesis. Light energy is gathered and utilised during photosynthesis in green plants to change waters, carbon dioxide, and minerals into oxygen- and energy-rich organic molecules.
What makes photosynthesis so crucial?The significance of photosynthesis Solar or radiant energy is converted into chemical energy during photosynthesis. The production of agricultural crops is directly impacted by the rate of photosynthesis. All living things require oxygen, which it provides for the atmosphere. It keeps the ecosystem's carbon dioxide and oxygen levels in check.

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.

D. in areas with different cloud types.
Answer:
the answer is C-in areas with different air pressures
Explanation:
Convection occurs when particles with a lot of heat energy in a liquid or gas move and take the place of particles with less heat energy. Heat energy is transferred from hot places to cooler places by convection. Liquids and gases expand when they are heated.

Explanation:
Innate Response:
"The innate immune system is the body's first line of defense against germs entering the body. It responds in the same way to all germs and foreign substances, which is why it is sometimes referred to as the "nonspecific" immune system. It acts very quickly: For instance, it makes sure that bacteria that have entered the skin through a small wound are detected and destroyed on the spot within a few hours. The innate immune system has only limited power to stop germs from spreading, though. The innate immune system consists of: Protection offered by the skin and mucous membranes AND Protection offered by the immune system cells (defense cells) and proteins."
Acquired Response:
"The adaptive immune system takes over if the innate immune system is not able to destroy the germs. It specifically targets the type of germ that is causing the infection. But to do that it first needs to identify the germ. This means that it is slower to respond than the innate immune system, but when it does it is more accurate. It also has the advantage of being able to "remember" germs, so the next time a known germ is encountered, the adaptive immune system can respond faster. The adaptive immune system is made up of: T lymphocytes in the tissue between the body's cells AND B lymphocytes, also found in the tissue between the body's cells AND Antibodies in the blood and other bodily fluids."
I'm sure it's Inflammation, so here is the definition for that:
"Inflammation refers to your body's process of fighting against things that harm it, such as infections, injuries, and toxins, in an attempt to heal itself. When something damages your cells, your body releases chemicals that trigger a response from your immune system."

Which type of evidence is often reviewed in microscopy?
OA physical evidence
OB.
trace evidence
OC. personal experience
OD
testimonial evidence
OE.
circumstantial evidence
Answer:
B. Trace Evidence
Explanation:
Trace evidence is like fiber or hair or gunshot residue to it would be B. Trace evidence
The physical evidence and trace evidence are both reviewed under microscopy. Therefore, option A and option B are correct statements.
What is microscopy?Microscopy is a technique to review the smaller size object at high magnification. Forensic science uses the physical or trace evidence found at the crime scene to review under microscopy.
Physical evidence refers to the tangible objects found at the crime scene, such as murder weapons or tool marks. On the other hand, trace evidence refers to the small or even microscopic pieces of evidence left at the crime scene, such as hair, or DNA.
Using the microscopy technique, the forensic team can determine the source of the murder weapon used at the crime scene or even link the suspect to the death of the victim. However, other types of evidence that do not come under microscopy, such as testimonial evidence or circumstantial evidence are also used to build a strong case against the suspect.
Therefore, the physical evidence and the trace evidence both are reviewed under microscopy.
