Dr. Flores wants to know which of the forum claims is best supported by the evidence you have gathered from your previous Sim observations and the text. Select the claim you think is best supported from the options below. Claim 1: Molecules in a substance disappear or no longer exist when a substance changes phase. O Claim 2: Molecules in a substance move differently when a substance changes phase. Claim 3: Molecules in a substance change into a new kind of molecule during a phase change.
Answer:
Claim 2: Molecules in a substance move differently when a substance changes phase.
Explanation:
Molecules in a liquid phase move freely and bump into each other. In a gas phase, the molecules move with a lot more energy and bump more times against each other; there is a lot of space for the molecules to move. In a solid phase, the molecules hardly move, there is not much space between them, and they are together, often in a regular pattern.
In conclusion, when matter changes from one phase to another, the molecules move differently.
Answer:
you will need to either add or take away energy and pay attention to how the molecules move. Molecules of a solid move in place, molecules of a liquid move around each other, and molecules of a gas move away from each other.

What is another major function of lipids besides energy?
In the spleen, ___________ from red blood cells is broken down to form (unconjugated) bilirubin. Unconjugated bilirubin is insoluble in blood plasma so binds to albumens in the blood and is sent to the ______. Bilirubin ___________ with glucuronic acid to form conjugated bilirubin. It forms part of the bile, which is ______ in the gall bladder. Food in the gut stimulates gall bladder contraction and the bile passes down the ____ ____ to the _____ _________, where it aids in the digestion of ______.
Answer:
Haemoglobin; liver; binds; stored; bile duct; small intestine; lipids.
Explanation:
Serology can be defined as the study of blood and the reactions between antibodies and antigens in the blood.
In Biology, blood pH can be defined as a measure of the hydrogen ion (H¯) concentration of blood i.e the level of alkalinity or acidity of blood.
Basically, the normal blood pH of a human being should be between 7.35 and 7.45.
Hence, one of the ways in which the body regulates blood pH is with proteins. Proteins help regulate blood pH by accepting and releasing hydrogen ions. Typically, when the blood pH falls, the hydrogen ions (H¯) are accepted (absorbed) while hydrogen ions are released when the blood pH rises.
For example, a protein such as haemoglobin which makes up a composition of the red blood cells, binds an amount of acid required to regulate blood pH.
In the spleen, haemoglobin from red blood cells is broken down to form (unconjugated) bilirubin. Unconjugated bilirubin is insoluble in blood plasma so binds to albumens in the blood and is sent to the liver. Bilirubin binds with glucuronic acid to form conjugated bilirubin. It forms part of the bile, which is stored in the gall bladder. Food in the gut stimulates gall bladder contraction and the bile passes down the bile duct to the small intestine, where it aids in the digestion of lipids.

How does heart rate change during and after an exercise is performed for two different periods of time?
Answer:
During exercise, your heart typically beats faster so that more blood gets out to your body. Your heart can also increase its stroke volume by pumping more forcefully or increasing the amount of blood that fills the left ventricle before it pumps.
Explanation:
During workout, the heart usually beats faster, allowing more blood to leave person's body. The heart can also boost stroke volume by pumping harder or increasing the amount of blood in the left ventricle before it pumps.
What is workout?A session of vigorous physical exercise or training at either gym, home, or any fitness center is referred to as workout.
The heart usually beats faster during exercise, allowing more blood to leave the body.
The heart can also increase by pumping the stroke volume more forcefully or increasing the amount of blood in the left ventricle prior to pumping.
Thus, heart rate change during and after an exercise is performed for two different periods of time.

How does the number of chromosomes
compare from original cell to new cells
produced?
Answer:
Once mitosis is complete, the cell has two groups of 46 chromosomes, each enclosed with their own nuclear membrane. The cell then splits in two by a process called cytokinesis, creating two clones of the original cell, each with 46 monovalent chromosomes.

Is a physical trait the same as a genetic trait? Please answer this very quickly! I don’t have that long until I have to turn it in!
Answer:
Physical traits are observable characteristics determined by specific segments of DNA called genes.In technical terms, a genetic trait is amenable to segregation analysis rather than quantitative analysis.
Explanation:
Trait is a specific characteristic of an individual. For example, their hair color or their blood type. Traits are determined by genes, and also they are determined by the interaction with the environment with genes. And remember that genes are the messages in our DNA that define individual characteristics.
Answer:
No
Explanation:
Physical characteristics are defining traits or features about your body
A genetic trait is a specific characteristic of an organism

Which substances are released into the small intestine of a human and aid in the digestion of the intestinal contents?
the answer to this is Duodenum
Bile, pancreatic juice, and intestinal juice are released into the small intestine of a human and aid in the digestion of the intestinal contents.
What is Intestine?The intestine is defined as the muscular tube that extends from the lower end of your abdomen to the anus, the lower opening of the digestive tract also known as the bowel or bowels.
The small intestine extends from the pyloric sphincter to the ileocecal valve, where it empties into the large intestine, while the small intestine completes the process of digestion, absorbing nutrients and passing waste to the large intestine. The liver, gallbladder, and pancreas are accessory organs of the digestive system that are closely related to the small intestine.
Large intestine is the long, tube-like organ that is connected to the small intestine at one end and the anus at the other. Some digestive juices like Bile, pancreatic juice, and intestinal juice are released during digestion from small intestine.
Thus, bile, pancreatic juice, and intestinal juice are released into the small intestine of a human and aid in the digestion of the intestinal contents.
