Answer:
the molecules at the surface are being pulled by other molecules. The pulling forces the water to curve. ... The positive hydrogen ends of one water molecule attract the negative oxygen ends of nearby water molecule.
Explanation:
Surface tension forces the surface of water to curve due to its tendency to reduce the surface area of water.
The surface tension of a liquid is in itself a tangential force acting parallel to the surface of the liquid due to the cohesive force of attraction between the molecules of the liquid.
The highly cohesive nature of water molecules means that the molecules at the air/water interface are more stuck together, creating elastic-like surface tension on the water. Thus, the water surface curves inward forming a concave shape.
In other words, the cohesive force of water molecules causes surface tension which in turn causes the surface area of water to reduce or curve inward.

Large molecules have very specific functions, specifically in the body. This particular molecule
helps to maintain glucose levels in the blood and is released from the pancreas. What is this
organic molecule?
A)
starch
B)
hemoglobin
C)
steroids
D)
insulin
Answers
Answer:
D) Insulin
Explanation:
Insulin is an organic molecule, specifically a protein molecule, which is produced by the pancreas. It is an enzyme that regulates the level of glucose in the blood. Insulin carries out this function by converting excess glucose in the blood into a stored form called GLYCOGEN.
The glycogen, which is stored in the liver, is converted back to glucose when the need arises for glucose in the blood. Hence, INSULIN is that large organic molecule (protein) that helps to maintain glucose levels in the blood and is released from the pancreas.

Rhonda Runsalot is a 20 year old woman. She is running at VO2max. Her heart rate is 200 b/min. Her stroke volume is 100 ml blood/b. Her arterial oxygen content is 20 ml O2/100 ml blood. Her venous oxygen content is 6 ml O2/100 ml blood. What is her cardiac output?
Answers
Answer:
Cardiac output = 20 L/min
Explanation:
The cardiac output of a person refers to the volume of blood the heart pumps in a minute. The normal range for cardiac output is about 4 to 8 L/min. However, this can vary depending on the metabolic needs of the individual at any instant of time, for example, it is higher when exercising than when resting.
Cardiac output is calculated from the product of the stroke volume in liters/min and the heart rate in beats/min
Cardiac output = stroke volume * heart rate
For the individual who is running; stroke volume = 100 mL/beat or 0.1 L/beat
heart rate = 200 beats/min
Cardiac output =0.1 L/beat * 200 beats/min
Cardiac output = 20 L/min

An estimate is defined as a reasonable assumption.
An approximation of a number, based on reasonable assumptions, is called estimation.
What is an Assumption?An assumption may be defined as an incident of accepting something true without any valid question or accurate proof. The assumptions may be falsified at any time. This is because it never contains some solid evidence.
Estimation is something that is predicted without any actual consent. It is just an approximation of numbers, objects, data, or any other thing that is only based on reasonable assumptions. The same concept is held by estimation as well.
Assumptions and estimations both have identical meanings to one another. This is because the principles or measurement of both depends on only approximation. They never represents the things based on accuracy and validity.
Therefore, an approximation of a number, based on reasonable assumptions, is called estimation.

During interphase, which is composed of the G1 phase, S phase and G2 phase, the cell grows and replicates its DNA and some of its organelles. During the S phase, the genetic material is duplicated into two sister chromatids, and centrosomes, which are nucleated microtubules that interact with the chromosomes to form the mitotic spindle, are also replicated. Metaphase is the third phase of mitosis, where sister chromatids align in the middle of the cell before their separation into two daughter cells.
