Answer:

Explanation:

Hydrophobic substances such as vegetable oil are nonpolar substances that repel water molecules.

Nonpolar substances are molecules that do not have a charge separation between different parts of the molecule. This means that they do not have a polar, or electrically charged, end, and as a result, they do not dissolve well in polar solvents like water.

Nonpolar substances are hydrophobic, meaning that they repel water molecules, and tend to dissolve in other nonpolar substances, such as oils and fats. Examples of nonpolar substances include hydrocarbons like gasoline, fats, oils, and waxes, as well as some gases, like nitrogen and methane. Nonpolar substances play an important role in a variety of biological and industrial processes, and their unique properties make them useful for many different applications.

Thermometer

Graduated cylinder

Explanation:

Measuring devices are used as follows -1. Thermometer, 2. Heart monitor, 3. Measuring cylinder, 4. Clock, 5. Tape measure

The instruments that are used for the measurements of various specific items based on the laws and the theories of measurement are called measuring devices.

Specific measurements have specific measurement devices. These measure the value based on the specific unit of the measurement.

For example, an inch tape measures the length of something in inches. It also has scales of centimetres and meters.

For the measurement of length, scales and tape measures are used.

For the measurement of time, clocks are used.

For the measurement of volumes, graduated cylinders are used.

For the measurement of temperature, thermometers are used.

Therefore, the measuring devices vary according to the function it needs to perform. In this case, 1. Thermometer, 2. Heart monitor, 3. Measuring cylinder, 4. Clock, 5. Tape measure.

Energy is transferred through the oceans, the atmosphere, and the geosphere by convection. Energy is transferred between the geosphere and the atmosphere by conduction.

Answer:

The particularly severe winter of 1777-1778 proved to be a great trial for the American army, and of the 11,000 soldiers stationed at Valley Forge, hundreds died from disease. However, the suffering troops were held together by loyalty to the Patriot cause and to General Washington, who stayed with his men.

Explanation:

Explanation:oceanic plates are formed at divergent boundaries mainly at mid ocean ridges. The material that is poured out are basaltic lave in nature. Basalt is denser and heavier than the granite that makes up continental plates.

Oceanic plates are much thinner than the continental plates. When an oceanic plate meets a continental plate at a convergent boundary the oceanic plate is forced under the continental plate and destroyed. The convergent boundaries between ocean and continental plates create subduction zones. The oceanic plate is pushed under the continental plate and melted. This melted material becomes magma that may reach the surface as volcanos, or solidify under the surface as granite.

Continental plates are much thicker that Oceanic plates. At the convergent boundaries the continental plates are pushed upward and gain thickness. The rocks and geological layers are much older on continental plates than in the oceanic plates. The Continental plates are much less dense than the Oceanic plates. The Granite and recycled material are much lighter than the heavy basalt layers of the ocean plates.

Answer: The endoplasmic reticulum (ER) is a large, dynamic structure that serves many roles in the cell including calcium storage, protein synthesis and lipid metabolism

Explanation: Hope this helped !

Answer:

It will shrink.

Explanation:

When  a solution contains more solute than the surrounding environment  where ,it  is located,it is said to be hyper tonic.Such a solution is of higher concentration,and therefore contains little water.

Syrup is an example of an hype tonic solution.Corn syrup  as an example  contains more solute in it,

Paramecium is unicellular organisms which is aquatic in habitat,therefore compare to the syrup of high solute it is hypo tonic.

Thus when placed in syrup,Paramecium loses water by osmosis,since water from the Paramecium at lower concentration would move out through the paramecium membrane ,as semipermeable membrane,into the syrup,of higher concentration

The paramecium will eventually shrink,and die,due to dehydration.

El efecto del material sobre el medio ambiente es el aspecto a considerar.

Explicación:

Se debe verificar la estructura química del material o de qué elementos se forma un material para conocer el efecto de estos materiales en la salud y el medio ambiente de las personas. Si los materiales no afectan el medio ambiente y la salud humana, el ser humano puede utilizarlos para satisfacer sus necesidades. Si el material se forma a partir de elementos tóxicos o elementos que no se descomponen por microbios, entonces este tipo de materiales son peligrosos tanto para la salud humana como para el medio ambiente porque estos materiales contaminan el medio ambiente y debido a esta contaminación la salud humana se ve gravemente afectada.

Chemotherapy i.e. use of drugs to destroy the cancer cells by inhibiting their growth and division. Therefore, option (A) of interrupting stages in cell cycle is correct.

Chemotherapy is a medication that employs strong chemicals to destroy rapidly developing cells in your body. Chemotherapy is most commonly used to treat cancer because cancer cells grow and proliferate significantly faster than the rest of the body's cells. There are several chemotherapy medicines available.

Taxol (Paclitaxel) and other drugs that poison microtubules and impede the mitotic spindle have been used extremely efficiently in chemotherapy. This prevents cancer cells from proliferating and kills them.

Therefore, pharmaceutical researchers uses drugs to learn cancer treatment. Option (A) is correct.

Answer:

use mathmatical representation to support explanation of factors that efect carrying capacity of ecosystems at different scales as support and revise evidence about factors affecting bio-diversity and populations in ecosystems of  different scales

Explanation:

Population models have been used to analyze and study population dynamics. It can be applied to real-world data to understand the carrying capacity of the ecosystem and factors affecting biodiversity.

The carrying capacity of the ecosystem is defined by the number of individuals or the population that can be entertained in a specific geographical area at a particular time.

The carrying capacity, population dynamics, biological invasions, conversation, and biodiversity can be explained by the population model.

The model describes the mechanistic and mathematical representation that allows a better understanding of dynamics and statistics. This is applied in the real world to understand the carrying capacity of the ecosystem.
