A. Convert the following as instructed :
i. 340 cm into m
ii. 67 kg into g
iii. 2 days into seconds
iv. 86,400 seconds into days
Plz help me to solve this problem
Answer:
340 cm = 3.4 m
67 kg = 67000 g
2 days = 172800 seconds
86,400 seconds = 1 day
i also see you are ARMY :)
i. 340cm : 100 = 3.4m
ii. 67kg × 1000 = 67000g
iii. 2 days × 24 =
48 hours × 60 =
2880minutes × 60 = 172800 seconds
iv. 86400seconds : 60 =
1440 minutes : 60 =

Explain how organelles and other structures interact to secrete substances from the cell.
Answer:
Organelle and other structures have vessels that are collectively referred to as the endomembrane system
The interaction of organelles and other structures to secrete substances from the cell is as follows:
Cell secretion is a long-lasting process by which a cell directs secretory vesicles out of the cell membrane.
In exocytosis, the proteins or molecules produced in the endoplasmic reticulum are enveloped in a vesicle towards the Golgi apparatus.
The substances pass through all the saccules of the Golgi apparatus and when they reach the trans face of the dichthyosome, in the form of secretory vesicles.
These are transported to their destination outside the cell, crossing the cytoplasmic membrane by exocytosis.
Golgi apparatus not only communicates with the membrane but with all the organelles found inside the cell, including peroxisomes and mitochondria.
Therefore, we can conclude that the reticulum and Golgi apparatus participate in secretion of substances from the cell, the vesicles fuse in the plasma membrane, thus releasing their content to the extracellular medium.

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.

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

What natural phenomenon is enhanced by the surplus carbon in the atmosphere?
Explanation:
surplus carbon in atmosphere...phenomenon, . makes the Earth very warm. helps plants on land...
By the addition of more surplus carbon to the atmosphere, the natural greenhouse effect gets changed which causes global temperature to rise and hence global warming.
What is Greenhouse effect?The greenhouse effect is heat which is trapped close to Earth's surface by the presence of greenhouse gases. These heat-trapping gases can be considered as a blanket wrapped around the Earth that keeps the planet warmer than it would be without them.
The increases in carbon dioxide are caused primarily by the human activities as carbon is produced by burning fossil fuels, pollution, etc. The disruption to Earth's climate equilibrium is caused by the increased concentrations of greenhouse gases which lead to an increase in the global surface temperature of the planet.

Choose the option that places the phases of a stem cell into the correct order.
A. Mitosis, gene expression, differentiation
B. Differentiation, mitosis, specialization
C. Gene expression, differentiation, mitosis
D. Mitosis, specialization, gene expression
Answer:
mitosis, gene expression, differentiation
Explanation:
The steps of mitosis, gene expression, and differentiation should be performed in the specific order for stem cells. Therefore, option (A) is correct.
What are stem cells?
Undifferentiated cells that have the potential to develop into a wide variety of other cell types in the body are referred to as stem cells. Stem cells are found in all multicellular organisms.
Before a stem cell can become differentiated, it must first go through the processes of growth and mitosis. Next, the information contained in the gene (DNA) of the cell must be expressed in order to determine the type of cell that the stem cell will become. Finally, the stem cell must differentiate and become specialized in order to give rise to a specific type of cell.
Stem cells dwell in bone marrow (the spongy center of certain bones). Here, fresh blood cells divide. After maturing in bone marrow, blood cells enter the bloodstream. Immature stem cells enter the circulation.

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)
