what is the importance of DNA copying in reproduction
Answer:
DNA copying is an essential part of the process of reproduction because it carries the genetic information from the parents to offspring.
Explanation:
Which organic compounds (carbohydrates, lipids, proteins, or nucleic acids) make up
muscle tissues, act as enzymes, and protect the body from antibodies?
Organic compounds that are essential for the body are called macromolecules. Proteins are the large molecules that make muscles tissues, and enzymes and act as antibodies.
What are the functions of proteins?Proteins are the major organic molecules that are involved in various roles and functions in the body. They are critical for the body's functioning and are involved in building muscle tissues and their repair.
They are also involved in acting as enzymes as they are made of amino acid sequences that provide the high molecular, 3-D structure that allows them to catalyze the activities.
The proteins also act as antibodies in the immune system as the immunoglobulin chains are made of variable and constant protein structures that count the antigens.
Therefore, proteins are involved in muscles, antibodies, and enzyme production.

How can simple molecules impact an organism’s ability to function normally ?
A student wants to determine if exercise helps one to learn better. She conducts an experiment where 10 people start an exercise program and 10 people do not exercise. During the first semester grades are recorded. Then, after the first semester, the people's roles are reversed. The exercisers stop their program and the non-exercisers start the exercise program. Grades are recorded for the second semester. Before and after grades are compared. F. What is the dependent variable? G. What is the independent variable? H. What variables need to be controlled (held constant) for this experiment to be fair? I. Does she have a control group? If yes, what is it? If no, what should it be?
Answer:
Independent variable: exercise
Dependent variable: grades
Constants: same kind of exercise, same set of students
Yes, there is a control group. The control group are the 10 people that do not exercise
Explanation:
In an experiment, the independent variable is that variable that the experimenter changes or manipulates. In this case, the independent variable is the EXERCISE.
The dependent variable is the variable that responds to changes made to the independent variable or the variable that the experimenter measures. In this case, the dependent variable is the GRADE of the people.
The constant is the variable that the experimenter must keep constant or unchanged throughout the experiment. In this experiment, the constants are the same kind of exercise, same set of people used.
In this experiment, there is a CONTROL GROUP. The control group is the group that does not receive the experimental treatment in the experiment. In this case, The control group are the 10 people that do not exercise

Explain in detail how high blood sugar and high blood pressure demonstrate a positive feedback loop.
Platelet aggregation and accumulation in response to injury is an example of positive feedback. Negative feedback brings a system back to its level of normal functioning. Adjustments of blood pressure, metabolism, and body temperature are all negative feedback.
The control of blood sugar (glucose) by insulin is a good example of a negative feedback mechanism. When blood sugar rises, receptors in the body sense a change. In turn, the control center (pancreas) secretes insulin into the blood effectively lowering blood sugar levels.
Examples of processes that utilize negative feedback loops include homeostatic systems, such as: Thermoregulation (if body temperature changes, mechanisms are induced to restore normal levels) Blood sugar regulation (insulin lowers blood glucose when levels are high ; glucagon raises blood glucose when levels are low)

Viruses comes in four different types of shapes such as Polyhedral, Sperical, Helical and Complex.
4. Discuss the difference between solar flares and CME's.
Answer:
CMEs are giant clouds of particles from the Sun hurled out into space, while flares are flashes of light—occurring in various wavelengths—on the Sun.
All three occur in the corona. The biggest difference is the cause. The solar wind is a constant flow of particles from the sun’s corona due to their high energy gained from the sun’s interior, it’s like being boiled off. CME’s and flares are the result of “explosive” releases of energy from the sun’s magnetic field.
One can think of the explosions using the physics of a cannon. The flare is like the muzzle flash, which can be seen anywhere in the vicinity. The CME is like the cannonball, propelled forward in a single, preferential direction, this mass ejected from the barrel only affecting a targeted area.

Lines on a globe that run north and south but give the angular distance east or west of the Prime Meridian are called lines of ___________________________ *
Explanation:
A circle such as around the globe is 360 degrees (�). Each degree may be further divided into 60 minutes (') and each minute into 60 seconds ("). A grid system or graticule is formed in this manner using a base of two perpendicular circles. Latitude measures the number of degrees north or south of the equator which has a latitude of 0�. Lines of latitude (parallels) run east-west around the globe and are used to measure distances NORTH and SOUTH of the equator. Since the equator is 0�, the latitude of the north pole, 1/4 of the way around the globe going in a northerly direction, would be 90�N. This is the highest latitude possible. All latitudes except for the equatore must be designated either north or south of the equator. The longitude coordinate is also needed, then, to designate one particular point on the earth's surface. Longitude measures the number of degrees EAST or WEST of the Prime Meridian which runs through Greenwich, England. The Prime Meridian has a longitude of 0�. Lines of longitude (meridians) running north-south around the globe measure distances EAST and WEST of the Prime Meridian. Directly on the opposite side of the earth from the prime meridian is located the 180� meridian. This is the highest longitude possible. All other longitudes must be designated either eastor west of the Prime Meridian. All meridians converge at the poles so exactly at the poles no longitude is given; the longitude of the poles is left blank. It is required that latitude be given before longitude (generally preferred in non-computer applications). Lines of latitude and longitude represent true geographic east-west and north-south directions despite the fact that on some maps the grid lines may be curved due to the problems of projecting the spherical surface of the earth onto the flat surface of a map. When giving the latitude and longitude coordinates, be sure to identify if the location is north or south, east or west of the base or reference lines!! At these lines, no direction can be given, so do not put a letter after the degree sign.
