Explanation:

the exhaust from cars, trucks, and buses releases nitrogen oxides and sulfur dioxide into the air. These pollutants cause acid rain

Answer:

The blue arrows in circles indicate that cool air is sinking

Explanation:

Warm air is less dense than cool air. For this reason, warm air rises, creating a low pressure region, and cool air, which is more dense than warm air, sinks creating a high pressure zone. In this description, the red arrows represent the hot air rising up to the sky, and the blue arrows represent the cool air sinking down. The reason warm air is less dense is because its molecules are further apart than when it is cold, making it lighter per cubed square foot.

So, we can conclude that option a) Warm air is rising is incorrect, because the warm air rising is represented by the red arrows pointing up form the land to the sky.

Options c) Cool air is less dense and d) warm air is more dense are also incorrect, because as mentioned before, cool air is more dense than warm air.

Answer:

D

Explanation:

Deforestation is when forests and trees are destroyed to create space for farming and buildings or collect wood.

Many different animals live in the forests, such as birds, squirrels, bears, deer and more. This means the forest is their habitat. If the forest is destroyed, then their habitats will be destructed. This leaves some animals without shelter and some without food. Therefore, the animals may die and biodiversity will decrease.

Therefore, the best answer is D. Destruction of habitats.

Answer: They separated in distance, by deep water, and tides. They isolated all new comers, and prevented many of the plants and animals from breeding.  

Explanation:

Answer:

Explanation:In this article we will discuss about the water relation in plants.

Plant physiology is the study of vital or functional activities of plants. And water is essential for these functional activities.

What for water is needed:

i. Water is absolutely essential for protoplasm because its hydration is essential for its proper organisation and proper functioning of its organelles.

ii. Water is the carrier of various dissolved substances like gases, minerals, organic and inorganic substances etc.

iii. Water is necessary for metabolic reactions of the cell e.g., photolysis of water.

iv. The rigidity and turgidity of cells is maintained by and large by water.

v. Water forms a continuous network throughout the plant through which dissolved substances move up.

vi. Water makes up the loss of water during transpiration and guttation.

Thus almost all the functional activities of plants depend on the water relation.

Under water relation we study the following points:

a) How does water enter into the plant – This functional activity is studied under the heading ‘Osmosis’.

b) How does water move up inside the plant – It is studied under ‘Ascent of sap’ or ‘Translocation of sap’.

c) How is water lost from the plant – It is studied under ‘Loss of water’ or ‘Transpiration’.

Diffusion:

The movement of the molecules of gases, liquids or solutes from the regions of higher concentration to the regions of lower conc., until the molecules are evenly distributed throughout the available space is known as Diffusion.

Diffusion Pressure Deficit/Water Potential (DPD/WP):

Diffusion pressure deficit (DPD) is also called suction Pressure (S.P). It is the ability of a cell to draw water. It is the force per unit area (i.e., pressure) by which water enters into a cell. A pure solvent is supposed to have maximum diffusion pressure.

When certain solute particles are added to the pure solvent, the diffusion pressure of the resulting solution is lowered. The amount by which the diffusion pressure of a solution is lowered than that of its solvent at the same temperature and atmospheric pressure, is called DPD. The term DPD was introduced by Meyer in 1938.  

But according to the recent trend, diffusion of water is explained in terms of Water Potential. DPD is the positive value whereas water potential is the negative value.

Turgor Pressure (T.P.):

T.P is the outward pressure exerted by the cell solution on the cell wall which is developed due to osmotic diffusion of water. In equilibrium inward pressure is also given by the cell wall on the cell solution in an equal amount, which is called wall pressure or Hydrostatic Pressure.  

Turgor Pressure is also called Pressure Potential (PP) which has positive value.

Chemical Potential:

The free energy per mole of a chemical substance is called its chemical potential. Chemical potential of water in a solution is reduced by the addition of solutes.

Osmosis:

i. Osmosis is essentially a special type of diffusion of liquids.

ii. The term ‘Osmosis’ was given by Abbe Nollel.

iii. Osmosis Means:

a) Movement of solvent.

b) From a region of lower concentration of solution.

c) To a region of higher conc. of solution.

d) Through semi-permeable membrane (SPM).

iv. Plasma or cell membrane is a semi-permeable membrane. At higher temperature plasma membrane becomes permeable.

Illustration:

Answer:

Example of osmosis.

Explanation:

Osmosis is the spontaneous net movement or diffusion of solvent molecules through a selectively permeable membrane from a region of high water potential to a region of low water potential, in the direction that tends to equalize the solute concentrations on the two sides.

Diffusion is the net passive movement of molecules or particles from regions of higher to regions of lower concentration.

The answer cannot be diffusion, and thus, is osmosis.

Answer:

S - Savannas are typically found in tropical or subtropical regions.

S - Savannas tend to have more trees and shrubs.

S - Savanna's climate is drier than that of a grassland.

G - Grasslands are found in temperature regions.

G - Temperature Grasslands are mainly devoid of trees, receive less rainfall than Savannas & endure broader temperature extremes.

G - Grasslands make up 25 percent of the Earth's land surface and dominate in regions with limited rainfall, which prevents forest growth. This results from nearby mountain ranges that cause rain shadows over adjacent open-range lands.

B - Both represent the world's richest and most diverse ecosystems. They both provide a home for a quarter of the world's population and a habitat for thousands of plants and animals.

B - Many species gather in vast numbers, graze on the varied grasses, and can be found nowhere else on Earth. The coexistence between wildlife and grasses is key to healthy ecosystems. Animal migrations regenerate the landscapes, by controlling pests, dispersing seeds, and trampling invasive species. Through this partnership, grasslands and savannahs generate vital benefits for both people and nature.

B - Ecosystems such as these two in specific are essential for climate mitigation – they store carbon, locking it deep in the soil and extensive root systems. They are the source of or support many of the world’s biggest rivers and wetlands, ensure food security, support livelihoods, and are embedded in the cultural identity of millions of people.

(Also, A savanna or savannah is a mixed woodland-grassland<---similarity)

Explanation: Just research. I decided to state 3 characteristics for both The Savanna and The Grasslands, and then 3 for "B" (both).

Answer:

When two surfaces slide over one another the tiny bumps push on each other. Friction causes a force on a surface that is in the opposite direction to its motion. Friction can be reduced by the application of lubricants.

Friction is an interaction between two objects in contact that opposes the relative motion of those two objects. It is not something fundamental (like gravity, or electromagnetic force), but it comes up enough that it will be worthwhile to talk about it.

https://brainly.com/question/28356847

Answer:

Friction is a force that opposes the motion of objects in contact with each other. When two objects are in contact, the surface irregularities of the two objects interlock and create a resistance to motion, which we call friction.

The amount of friction that occurs between two surfaces depends on several factors, such as the type of materials involved, the force pressing the surfaces together, and the roughness of the surfaces. In general, rougher surfaces create more friction than smoother surfaces.

Friction can either help or hinder motion. For example, in some cases, we use friction to our advantage to create traction between our shoes and the ground to prevent slipping. Similarly, we use friction to slow down moving objects like brakes on a car.

On the other hand, friction can also be a source of energy loss. When two surfaces are in contact and rubbing against each other, some of the energy of the moving object is converted to heat due to the frictional force. This conversion of energy to heat can lead to wear and tear on the surfaces and reduce the efficiency of mechanical systems.

Overall, friction plays a crucial role in our daily lives and in the functioning of many mechanical systems. Understanding the interactions between friction and objects is important for engineering and designing effective machines and structures.
