Students have a small steel ball and a large steel ball, and they have a short ramp and a tall ramp.
The students want to find out if a ball's size affects how far it can roll. They also want to find out if the height of the ramp affects how far the ball can roll.
They do the following experiment:
**Written Response** What can they conclude from this experiment? Why?
Answers
Answer:
I think the height of the ramp affects the distance that the ball can go, but the size doesn't affect it
and as you decrease th height of the ramp it will look like straight thing, when it look like that the ball might need a little force in order to get speed also to go far
but in this condition the size can affect the ball distance it also depends on how much you give to it
Thank you !

When glycogen is formed from monosaccharides, it occurs by a process called hydrolysis.
True
False
Answers
Answer:
yes its true. it occurs by a process called hydrolysis
The formation of glycogen from monosaccharides happens through the process of dehydration. So the statement is false.
What is the process of glycogen formation?
The process of formation of glycogen is called glycogenesis. Glycogen is the storage form of glucose, a primary carbohydrate in the liver and the muscle cells of animals
The process of Glycogenesis happens when the levels of glucose in the blood are high enough to allow the excess glucose to be stored.
The process of glycogenesis is stimulated by the insulin hormone. It helps the muscle cells to uptake glucose into themselves. Insulin is not required for the transport of glucose into the liver cells.
However, insulin has very important effects on the metabolism of glucose inside the liver cells. Insulates stimulates the process of glycogenesis and inhibit the process of glycogenolysis, which is the breakdown of glycogen into glucose.
Therefore the statement is false.

9.During exercise, blood flow to skeletal muscles increases. The initial response that increases blood flow is automatic in independent of the nervous and endocrine systems. Which type of homeostatic regulation is this (extrinsic or intrinsic)
Answers
Answer:
Extrinsic Homeostatic Regulation
Explanation:
Extrinsic homeostatic regulation requires input from nervous system or endocrine system. The skeletal muscles are independent on the nervous and endocrine system, so therefore the homeostatic regulation is extrinsic.

As you walk down the hall on the way to class, several students sneeze. You unknowingly inhale some of the droplets
that were expelled when they sneezed, allowing the flu virus to enter your body. Explain the nonspecific immune
defenses that the virus must bypass in order to infect a body cell. (5 points)
Answers
Answer:
The innate or nonspecific immune system includes two lines of defense in the human body. Non-specific means that it does not act on the specific pathogen. It works equally to keep all types of pathogens such as bacteria, viruses, parasites et cetera out of the body. The first line of defense includes physical barrier which prevents the entry of pathogens into the body. It includes skin, respiratory tract, gastrointestinal tract, cilia, nasopharynx, eyelashes, and body hairs.
The second line of defense includes anti-inflammatory responses, fever, and nonspecific cellular responses such as phagocytes, macrophages, complement system et cetera. Thus, the virus has to pass physical, chemical, and nonspecific cellular responses of the body in order to infect the body.
Explanation: I found this answer on a different site and it was right, no need to thanks me, no problem
The antiviral defense is composed of changes in cells that prevent viral replication and increase susceptibility to death by lymphocytes.
What innate defense mechanism against viruses?Viral replication interferes with protein synthesis and cell function and leads to injury and death of the infected cell. The main mechanisms of innate immunity against viruses are inhibition of type I interferon infection and NK cell-mediated destruction of infected cells.
With this information, we can conclude that the antiviral defense is composed of alterations in the cells that prevent viral replication and increase the susceptibility to death by lymphocytes, thus eliminating the reservoirs of viral infection.

Answers
Answer:
Because the facilities here for my subject are second to none” – this shows that your subject has been at the forefront of your mind when making a sensible choice of university, again demonstrating your level of commitment to it. You can mention specific facilities to show that you’ve read into it thoroughly.
“Because I liked the approach this university takes to my course” – even within the same subject, every university takes a slightly different approach to the way it’s taught and structured. The university question is another good opportunity to show that you’ve really thought about the course and gone to the effort of finding a university whose approach to the subject you agree with. You can even name specific modules that set this university’s course apart from the others offering the same subject.
Along similar lines, you could also mention the university’s great reputation for your subject, or the presence of certain lecturers you feel inspired by (though don’t let this last point dominate your answer; lecturers often move about or go on sabbatical, so even if there’s a particular academic you admire, they may not end up teaching you).

nucleotides
Answers
Answer:
D. nucleotides
Explanation:
The monomers of DNA are called nucleotides. Nucleotides have three components: a base, a sugar (deoxyribose) and a phosphate residue. The four bases are adenine (A), cytosine (C), guanine (G) and thymine (T). The sugar and phosphate create a backbone down either side of the double helix.
D. Nucleotides.
Nucleotides are the name given to DNA's monomers. A backbone is formed by the sugar and phosphate down either side of the double helix.
What is the synthesis of DNA?These nucleotide units bind together to produce DNA, which can happen naturally or artificially (in vitro) (in vivo). A nitrogenous base (cytosine, guanine, adenine, or thymine), pentose sugar (deoxyribose), and phosphate group make up a nucleotide unit.
DNA replication is the process through which new DNA strands are created in living cells.
All living cells in the natural world synthesize DNA molecules through the process of DNA replication. This frequently happens during cell division. DNA replication happens so that each daughter cell has a precise copy during cell division.
