Answers

Answer:

xlimate change is when the climate change due to green house effect

So, climate describes the long term pattern of weather conditions that occurs in a locality. Thermometers and rain gauges are used to collect weather data. These days temperatures are also taken by satellites to reduce the possibility of false high readings due to heat in cities. We can't take Earth's temperature directly, but we do have a lot of information from weather stations, ocean buoys and remote sensing instruments. The information lets us see changes in climate.

B. Is what the scientists manipulate in the experiment
C. The component that is measured. D. The results of the experiment​

Answers

Answer:

B. Is what the scientists manipulate in the experiment.

Explanation:

The Independent variable is not dependent, or doesn't rely, on another variable in the experiment. So, it would make the most sense that they would manipulate the Independent so that they can watch and see how the dependent variable reacts to the manipulation, or the change, in the independent variable.

Using information from the diagram, state one reason why the movement in the third image represents active transport

Answers

Answer:

A protein or ion has passed through the "pump" or carrier proteins and move within the cell.

Nvm short and sweet ;)

Further info..

To move substances against a concentration or an electrochemical gradient, the cell must use energy. This energy is harvested from ATP that is generated through cellular metabolism. Active transport mechanisms, collectively called pumps or carrier proteins, work against electrochemical gradients. With the exception of ions, small substances constantly pass through plasma membranes. Active transport maintains concentrations of ions and other substances needed by living cells in the face of these passive changes. Much of a cell’s supply of metabolic energy may be spent maintaining these processes. Because active transport mechanisms depend on cellular metabolism for energy, they are sensitive to many metabolic poisons that interfere with the supply of ATP.

true or false? diffusion is a result of the random movement of particals

Answers

The kinetic energy of the molecules results in random motion, causing diffusion. In simple diffusion, this process proceeds without the aid of a transport protein. it is the random motion of the molecules that causes them to move from an area of high concentration to an area with a lower concentration. The rate of this movement is a function of temperature, viscosity of the fluid and the size (mass) of the particles. Diffusion explains the net flux of molecules from a region of higher concentration to one of lower concentration. However, diffusion can still occur in the absence of a concentration gradient. Diffusion requires energy input from the cell. ... Only water can diffuse across a cell membrane. Molecules move from areas of high concentration to areas of low concentration. - Passive transport is the diffusion of substances across a membrane. - Facilitated diffusion is the process of spontaneous passive transport of molecules or ions across a cell's membrane via specific proteins. Concentration gradient, size of the particles that are diffusing, and temperature Examples of diffusion in living organisms

Oxygen and carbon dioxide, dissolved in water, are exchanged by diffusion in the lungs: oxygen moves down a concentration gradient from the air in the alveoli to the blood. carbon dioxide moves down a concentration gradient from the blood to the air in the alveoli. What determines the direction of any diffusion process? The relative concentration of the substance in different areas determines the direction of diffusion. Diffusion occurs from regions of high concentrations to regions of low concentration. What determines the direction of any diffusion process?

What is a cell membrane made of?

The cell membrane, also known as the plasma membrane, is uncovered in all cells and serves to separate the cell's interior from the outside environment.

The cell membrane is made up of a semipermeable lipid bilayer. The cell membrane controls the transport of materials into and out of the cell.

These are glycerophospholipids, which are molecules made up of glycerol, a phosphate group, and two fatty acid chains. Glycerol is a three-carbon compound that serves as the membrane lipids' backbone.

As, these non-polar fatty acids are insoluble in water, so it protect the cell membrane from water. It actually prevent the cell membrane to get dissolve in the water.

Thus, the correct option is A.

deciduous forest Predict which sample would have a greater concentration of organic
material Explain your answer

Answers

Answer:

Temperate deciduous forest

Explanation:

The temperate deciduous forest will have more organic matter concentration in it.

Organic matter is a component of biological relics found in the soil. It makes up a significant portion of the soil.

Soil organic matter should not be confused with biomass production. Rainforest due to its biodiversity is rich in organic biomass. These organic matter decays rapidly due to the humid conditions, and are become lost. Also, the rate of weathering in the rainforest is very high. This often washes and removes organic matter from the soil. These conditions are not so in the temperate forest.

Which of the following indicates that an endothermic reaction has occurred?
O Heat is released
O water is formed
O Salt is produced
O Temperature decreases

Answers

Heat is released because endothermic is the absorption of heat

The  following indicates that an endothermic reaction has occurred when temperature decreases, which is in the last option as the endothermic reaction needs heat to carry out the reactions.

What is the significance of the endothermic reaction?

There are two types of reactions, such as the reaction that requires heat to form the product, the endothermic reaction, while some of the reactions that release heat are called the exothermic reaction, and the exothermic reactions have more energy at the reactant side than the product side. In the case of a endothermic reaction, the product usually has more energy than the reactants, and the change in free energy here is positive.

Hence, the following indicates that an endothermic reaction has occurred when temperature decreases, which is in the last option as the endothermic reaction needs heat to carry out the reactions.

An animal cell with a 30% salt solution is placed in a beaker with a 20% salt
solution. Which is the correct conclusion if the cell remains in the beaker for an
extended period of time?

Answers

Answer:

the animal cell will burst

Explanation:

If the salt solution in the animal cell is 30%, it means the water is at a 70% concentration. Outside is 20%, so the water is 80%.

Water will enter the cell. Water is at a higher concentration outside the cell (80%) or a lower concentration inside the cell (70%) by the process of osmosis.

Eventually, the animal cell will burst, because it does not have any cell wall to control the swelling of the cell that occurs as water flows in.

How do oxbow lakes form? A. It is formed as lakes grow larger due to erosion and begins to look like an ox. B. It is formed when a bend in a river is cut off to form a lake. C. It is formed when a delta grows large enough to cut off a river to form a lake. D. It is formed when a dam stops the flow of a river and creates a lake.

Answers

Answer:

Oxbow lake is formed when a bend in a river is cut off to form a lake.

Explanation:

OPTON A - It is formed as lakes grow larger due to erosion and begins to look like an ox.

This statement is incorrect , as the shape of the oxbow lake is not like an ox , it is a horse-shoe shaped lake .

OPTION B - It is formed when a bend in a river is cut off to form a lake.

This statement is correct , as  An oxbow lake is a U-shaped lake that forms to create a free-standing body of water when a large meander of a river is cut off.

OPTION C - It is formed when a delta grows large enough to cut off a river to form a lake.

This statement is also wrong, as a river delta is specified by this statement.

OPTION D - It is formed when a dam stops the flow of a river and creates a lake.

This statement is also false, since the creation of a reservoir is established by this statement.

FORMATION OF OXBOW LAKE -:The neck of the meander gets narrower and narrower progressively. The curve gradually grows so close that the river slices through the neck of the meander to take a new, straighter path. Sediment locks the end of the old loop over time. This leaves a region of water that is different, called an oxbow lake.

Hence , the correct option is B.
