A laboratory assistant prepared solutions of 0.2 M, 0.4 M, 0.6 M, and 0.8 M sucrose but forgot to label them. After realizing the error, the assistant randomly labeled the flasks containing these four unknown solutions as flask A, flask B, flask C, and flask D. To determine the concentrations of each solution, the assistant filled four dialysis tubes with the four different solutions, took their initial masses, and placed each tube into distilled water overnight. The next day, the masses of each dialysis tube again were recorded. Using the data below, determine which concentration of sucrose solution is in each flask.

Answers

Answer:

To determine the flask on basis of the molarity or concentration of the solutions, an individual should design an experiment with the help of using water and dialysis tubes. Dialysis tubes up should be filled with pure water, then seal or closed them from both ends.

Measure the weight and note the mass of each tube, student should stick label the cups with the solutions. Weighing the solutions after leaving them for 8 to 10 hours. The tubes would lose weight as water leave the tube when placed in the solutions due to the principle of diffusion- movement.

The measure of the chemical constituents of the specific solute in a solution is called molar concentration.

For the determination of the flasks based on the molarity and concentration, the experiment should be designed based on dialysis tubes and water.

The dialysis tubes should be filled with pure water and both the ends of the tubes should be sealed.

The tubes should be measured and marked. Place the tubes into the solutions and after leaving them overnight weigh them again.

The weight of the tubes will decrease because of the flow of water.

Therefore, due to diffusion movement, the tubes will lose weight and the concentration of the flasks can be determined.

What is the blending theory of inheritance? Why did Mendel question this theory?

Answers

Answer:

Blending Theory of Inheritance

Mendel noticed plants in his own garden that weren't a blend of the parents. For example, a tall plant and a short plant had offspring that were either tall or short but not medium in height. Observations such as these led Mendel to question the blending theory

The blending theory state that the inheritance of traits from two parents produces offspring with characteristics that are combination of the parents.

What is blending theory of inheritance?

Blending theory of inheritance stated that, offspring is combination of characteristics of the traits from two parents. Blending inheritance was discarded after the general acceptance of the modern genetics.

Mendel noticed that plant in his garden were not blend of the parents.  For example, a tall plant and a short plant had offspring that were either tall or short but not medium in height.

Therefore, Mendel question this theory. He wanted to know if there was different principle that could explain how the characteristics are inherited to the offspring from parents.

The cell membrane serves many functions. One of the cell membranes functions is to help the cell maintain homeostasis. How does the cell membrane do that ?

Answers

Answer:

The cell membrane help to maintaining homeostasis by regulating the flow of substances through it and by recognizing potentially harmful agents to the cell.

Explanation:

Cellular membrane is constituted by a lipidic bilayer, whose characteristics allow it to behave as a semi-permeable membrane to the passage of substances.

The selective permeability of the membrane makes it possible to regulate the passage of water, molecules and ions through it into the cell and from there into the extracellular space, a characteristic that allows the maintenance of homeostasis.

Additionally, the cell surface can identify foreign and potentially harmful agents, which can affect the internal balance, preventing in most cases their passage into the cell.

Answer:

Explanation:

Air mass, in meteorology, large body of air having nearly uniform conditions of temperature and humidity at any given level of altitude. Such a mass has distinct boundaries and may extend hundreds or thousands of kilometres horizontally and sometimes as high as the top of the troposphere (about 10–18 km [6–11 miles] above the Earth’s surface). An air mass forms whenever the atmosphere remains in contact with a large, relatively uniform land or sea surface for a time sufficiently long to acquire the temperature and moisture properties of that surface. The Earth’s major air masses originate in polar or subtropical latitudes. The middle latitudes constitute essentially a zone of modification, interaction, and mixing of the polar and tropical air masses. Continental Polar (cP) air usually forms during the cold period of the year over extensive land areas such as central Asia and northern Canada. It is likely to be stable and is characteristically free of condensation forms. When heated or moistened from the ground with strong turbulence, this type of air mass develops limited convective stratocumulus cloud forms with scattered light rain or snow showers. In summer strong continental heating rapidly modifies the coolness and dryness of the cP air mass as it moves to lower latitudes. Daytime generation of cumulus clouds is the rule, but the upper-level stability of the air mass is usually such as to prevent rain showers. The continental Tropical (cT) air mass originates in arid or desert regions in the middle or lower latitudes, principally during the summer season. It is strongly heated in general, but its moisture content is so low that the intense dry convection normally fails to reach the condensation level. Of all the air masses, the cT is the most arid, and it sustains the belt of subtropical deserts worldwide. The maritime Tropical (mT) is the most important moisture-bearing and rain-producing air mass throughout the year. In winter it moves poleward and is cooled by the ground surface. Consequently, it is characterized by fog or low stratus or stratocumulus clouds, with drizzle and poor visibility. A steep lapse rate aloft in regions of cyclonic activity ensures the occurrence of heavy frontal and convective rains. In summer the characteristics of the mT air mass over the oceans and in zones of cyclonic activity are basically the same as in winter. Over warm continental areas, however, the air mass is strongly heated so that, instead of fog and low stratus clouds, widely scattered and locally heavy afternoon thunderstorms occur.

What is a small ecosystem in danger of compared to a large and diverse ecosystem?

Answers

Answer:

See the answer below

Explanation:

A small ecosystem is in danger when compared to a large and diverse ecosystem because the genetic variability in a small ecosystem is low and a small disruption can wipe out the populations within the ecosystem. This is unlike in a large ecosystem where this is a high genetic variability that gives the populations within the ecosystem resilience against disturbances.  

There are enough alleles within the genetic pool of a large and diverse ecosystem to withstand disturbance regimes unlike in small ecosystems where the alleles are few. Hence, a little disturbance can endanger the entire population in a small ecosystem and put them at the risks of extinction.

Answers

Answer:

B. Chemical - Cellular - Tissue - Organ - Organ System - Organism

Explanation:

The human body's hierarchical system that builds from smallest to largest units is : Chemical - Cellular - Tissue - Organ - Organ System - Organism.

Chemicals such as oxygen and carbon dioxide are the basic unit of the human body that forms atoms and biomolecules which further undergo chemical reaction to form cell or cellular, which is a basic unit of all life. Cells then form their functional groups called tissues and then different tissues form an organ. Different organs work together and form an organ system such as the digestive system and respiratory system. All the organ systems then form a living organism or human.

Hence, the correct option is "B. Chemical - Cellular - Tissue - Organ - Organ System - Organism".

Knowing what you know about how a substance travels in diffusion, in
order for oxygen to leave the alveoli and enter the blood, there would be
concentration of oxygen in the alveoli compared to the
blood. *
A.higher
B.Lower

Answers

Answer:

the oxygen should be concentrated in the alveoli

Explanation:

Diffusion: The movement of molecules from a region og higher concentration to a region of lower concentration.

So when the Oxygen is concentrated in the alveoli only then it can move towards the blood

Diffusion is a passive transport system which means it doesnt need energy in the form of atp molecules

if the molecules move from a region of lower concentration to a region of higher concentration it needs atp molecules which is energy and is called active transport system

Tina-Marie accidentally left her water bottle outside on a freezing, winter night. The next day, the water bottle, which is now filled with ice, ruptured. Based on her observations, Tina-Marie forms a hypothesis about freezing water and volume. Identify a hypothesis Tina-Marie can investigate. Then describe an experimental procedure for investigating the hypothesis.

Answers

Answer:

Hypothesis, Ice is less dense then water.

Explanation:

They could test this by attaining the density of ice and water, the density of Water is 1g/ml and if the ice floats that means ice is less then 1 g/ml which means ice is less dense. This is relevant to the water bottle because the Ice expanded due to it being less dense causing the water bottle to rupture
