which of the following properties of water are essential for life on Earth?​

A) polarity

B) Cohesion & Adhesion

C) High heat capacity

D) All the above

Solution

Some essential properties of water are as follows –  

a) Polarity

b) Solvent

c) High heat capacity - it is essential to maintain the temperature on earth. The water bodies are comparatively cooler than the temperature of earth

d) High heat of vaporization

e) Cohesion – It is essential for surface tension & capillary action

f) Adhesion – It is essential for surface tension & capillary action

g) Lower freezing density – Due to this reason, ice is lighter than water

Hence, option D is correct

Answer:

The salt doesn't flow into the cells much and the water doesn't leave much. Algae and plants can get away with having water attracted into their cells because they have a rigid cell wall outside the delicate cell membrane.

Prey and Predator

Explanation:

rabbit is the prey and leopard is the predator

Answer:

Parisitism.

Explanation:

Im pretty sure the answer is parasitism because the Leopard would feed on the rabbit, meaning the leopard benifits while the rabbit would be harmed.

Answer:

d. The protease inhibitors inhibit the late protein synthesis and processing of the human immunodeficiency virus.

Explanation:

Protease inhibitors are antiviral agents used to fight against pathogenic viruses such as retroviruses (e.g., human immunodeficiency virus, HIV) and RNA viruses (e.g., hepatitis C virus). Protease inhibitors can drastically reduce the viral load. Protease inhibitors may target 1-virus-encoded proteases which are responsible to produce functional proteins from polyprotein precursors and 2-processing structural proteins that are required for virus assembly. Some examples of protease inhibitors include, among others, ritonavir and indinavir, which are used in patients with HIV infection.

Answer:

The actual gas that causes air pollution is called a pollutant

Explanation:

Air pollution is the decrease in air quality. Air pollutants are the gases that cause air pollution.

Pollutants are harmful substances and particles that affect the quality of the environment and are man-made or natural. Fly ash from volcanic eruptions is a natural pollutant that deters the air quality.

The air pollutants like carbon monoxide, sulfur dioxide, and carbon dioxide released from the burning of fossil, coal, and vehicles alter the air quality and result in a change in weather conditions.

Therefore, the pollutants are the actual gases that cause air pollution.

Explanation:

Answer:

By using carbon-14 in the experiment in order to prove the statement.

Explanation:

Translocation occurs in the plant body in order to transport amino acids and sucrose from one part to another by the phloem tissues. In order to prove this, we have to incorporate radioactive element in the amino acid or sucrose which shows us that through which layer the amino acids and sucrose move in the plant body. For this purpose, carbon-14 can be used to trace the path of the translocation of amino acids and sucrose. Through this experiment we will find out that phloem layer is the path used by the plant to move amino acids and sucrose from one part to another.

Answer:

Lower Salinity in the ocean water.

Explanation:

The ocean absorbs most of the excess heat from greenhouse gas emissions, leading to rising ocean temperatures. Increasing ocean temperatures affect marine species and ecosystems. Rising temperatures cause coral bleaching and the loss of breeding grounds for marine fishes and mammals.

Evaporation of ocean water and formation of sea ice both increase the salinity of the ocean. However these "salinity raising" factors are continually counterbalanced by the continuous input of fresh water from rivers, precipitation of rain and snow, and melting of ice.

As temperature increases, the space between water molecules increases—also known as density, which therefore decreases. ... Salinity and density share a positive relationship. As density increases, the amount of salts in the water—also known as salinity, increases

Prokaryotic cell-- no organelles, no membrane.

Eukaryotic cell -- Have organelles and membrane.

Explanation:

For the model of prokaryotic cell, we construct the model by removing organelles from the cell whereas in the eukaryotic cell, we add the organelles because in eukaryotic organisms, organelles are present in the cell that performs specific function. In the model of prokaryotic cell, we have to remove membrane around the nucleus whereas membrane president around the nucleus. In the prokaryotic cell, nucleus is not visible while on the other hand, in eukaryotic cell, the nucleus is visible and can be differentiate from other organelles.
