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.

D=m/v

D=50/10

D=5

The density of an object that has a mass of 50 g and a volume of 10 ml would be:

Density = Mass / Volume

= 50 g / 10 ml

= 5 g/ml

Density is a measure of the mass of an object per unit of volume. It is a characteristic property of a substance and is often used to identify and classify materials. The density of an object can be affected by a variety of factors, including its composition, temperature, and pressure.

In general, denser materials tend to be heavier and more compact, while less dense materials tend to be lighter and less compact. For example, a substance with a high density, such as gold, will be much heavier than a substance with a low density, such as air.

Overall, the density of an object can be useful for understanding its physical properties and how it will behave in different situations.

cell membrane -----cytoplasm----- nuclear membrane----- gene

Explanation:

A cell is made up of three part this include the cell membrane, the cytoplasm and the nucleus.

cell membrane encloses the cells and it prevent external material from getting inside the cell while the nucleus is formed by a nuclear membrane around a fluid nucleoplasm. chromatin in the nucleus contain deoxyribonucleic acid (DNA) which is the genetic material of the cell.

The cytoplasm is fluid found in the cell. It is gel like in nature and a medium for chemical reaction.

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.

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

Absolute dating is used to determine a precise age of a fossil by using radiometric dating to measure the decay of isotopes, either within the fossil or more often the rocks associated with it.

Answer:

Organisms that have a narrow temperature tolerance range cannot survive in a wide variety of temperatures. Even small changes in climate can affect organisms that do not have a high tolerance for change. These organisms will be forced to adapt, relocate, or die off. If climate change is widespread, such organisms may not be able to survive.

Explanation:

edg2020

These organisms are known as stenothermal , since they are restricted to narrow range of temperature, any change in temperature would affect them significantly.

A stenotherm is a species or living organism only capable of living or surviving within a narrow temperature range. The opposite is a eurytherm, an organism that can function at a wide range of different body temperatures.

Stenothermal creatures require environments that maintain a constant temperature throughout the year in order to survive. They can only function within a very specific temperature range. Polar regions and tropical regions both have a temperature range that is rather small.

Crustaceans, insects, salmon, penguins, pythons, and other animals, such as these, are all examples of stenothermal species.

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.

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.

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.

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.
