Which word describes the difference between the highest and lowest points in an area?
elevation
landform
relief
topography
Answer:
relief
Explanation:
The difference in elevation between the highest and lowest parts of an area.
The elevation term is usually used to define how high a point is from the plane surface. It is used as a measure of the difference between two points.
-----------------------------------------------
When talking about relief, we refer to everything that is over the plane or the surface. The term refers to the different forms on the earth's surface that might reach different heights and shapes. When talking about topography, we refer to the discipline or technique that makes a detailed description of a surface. It describes the relief. The term landforms refer to abrupt and sharp land irregularities. Elevations, depresions, bankruptcies, roughness, among others. These are natural characteristics of the earth's surface. Finally, the term elevation refers to the highest part of something. It is used as a measure that reflects the angle formed over the horizontal plane. Geographically, it refers to a piece of land that is over the plane surface surrounding it.Among all these terms, the only one that best describes the difference between the highest and lowest points is elevation. The term is closely related to the altitude term.
For instance, when saying that the peak of Pico de Orizaba has an elevation of 5,636 meters, we refer to the difference existing from the sea level to Pico de Orizaba's highest point.

What do you mean by Cell organelles?Cell organelles may be defined as the type of subcellular structure which are present in the cytoplasm of the cell and has one or more specific jobs to perform in the cell. Some examples of cell organelles are the endoplasmic reticulum, mitochondria, lysosomes, Golgi bodies, etc.
Ribosomes are known as the site of protein synthesis which are present over the surface of the rough endoplasmic reticulum. These synthesized proteins are then migrated to the Golgi bodies through secretory vesicles where they are modified and sorted based on their destinations.
The waste proteins or those proteins which are now not required by the cell in order to accomplish metabolic functions, these types of proteins are degraded by the Lysosomes.
Therefore, the correct option for this question is D.

A part of the Calvin cycle has been removed from the diagram on the right. What occurs at this stage of the cycle? Carbon fixation CO2 Rubisco Calvin cycle PGA RuBP Reduction Regeneration ADP ATP ATP ADP NADPH DONE NADP G3P ?
Answer:
Edge Answer
Explanation:
Two G3P molecules leave the cycle.
The G3P molecules are used to make organic molecules like glucose and sucrose.
Calvin cycle is a process through which atmospheric carbon fixation takes place. In this step, NAPDH is converted to NADP with the formation of glyceraldehyde-3-phosphate. Thus, the correct option is D.
What is Calvin cycle?
Calvin cycle is a set of light-independent reactions which converts the atmospheric carbon dioxide and hydrogen-carrier compounds into glucose with the formation of ATP and NADP.
Calvin cycle is divided into three phases: Carbon fixation, Reduction, and Regeneration. Carbon fixation includes carboxylation phase in which atmospheric carbon dioxide reacts with the Ribulose-1,5-Bisphosphate in the presence of enzyme Ribulose-1,5-bisphosphate carboxylase/oxygenase (RubisCO) to form a three-carbon compound, 3-PGA (3-phosphoglyceric acid) which undergoes a reduction reaction to form glyceraldehyde-3-Phosphate (G-3-P) with the formation of NADPH to NADP.
In the regeneration step of calvin cycle, two molecules of G-3-P in the presence of ATP combines to form Ribulose-1,5-Bisphosphate and ATP.
Therefore, the correct option is D.

In a healthy ecosystem, which trophic level should
have the most energy?
Answer:
primary consumer
Explanation:
I'm doing this because it need 20 characters
The maximum concentration of energy is found in an ecosystem's fourth tropic level, or the first trophic level of the food chain.
What is the trophic level?Because it has the greatest energy, the first tropic level has the highest biomass. The lowest and greatest level of the pyramid is the producers, and it contains the most energy.
The amount of energy diminishes and the levels get smaller as you progress up the pyramid, via the trophic levels to primary, secondary, and tertiary consumers.
Therefore, the biggest concentration of energy is found in the initial trophic stage, which is known as the foundation of an ecosystem. This energy is transferred to organisms at other trophic levels.

What is the difference between osmosis & diffusion?
What are the TWO types of active transport?
What are the TWO types of passive transport?
Substances can only move into or out of a cell if the cell membrane is ___________________.
Explanation:
osmosis is the movement of solvent particles across a semipermeable membrane diffuison is the movement of particles from area of higher concentration to lower concention
primary active transport and secondary active transport
diffusion or water carbon dioxide
In diffusion, particles move from an area of higher concentration to one of lower concentration until equilibrium is reached. In osmosis, a semipermeable membrane is present, so only the solvent molecules are free to move to equalize concentration.
2. What are the TWO ,types of active transport?There are two types of active transport: Primary active transport that uses adenosine triphosphate (ATP)and secondary Active transport that uses an electrochemical gradient.3. What are the TWO types of passive transport?
Simple Diffusion and osmosis are both forms of passive transport and require none of the cell's ATP energy.
4. Substances can only move into or out of a cell if the cell membrane is:
Active Transport.
Those proteins do much of the work in active transport. They are positioned to cross the membrane so one part is on the inside of the cell and one part is on the outside. Only when they cross the bilayer are they able to move molecules and ions in and out of the cell.
