The right answer is D. modifying, sorting, and packaging proteins prior to transport.

The Golgi apparatus is one of the organelles necessary for the production of functional proteins.

The Golgi apparatus is a eukaryotic cellular organelle.

The Golgi apparatus is a transit and reservoir for proteins and lipids made in the endoplasmic reticulum. This is part of the network of internal membranes that have put in place to transport macromolecules.

In particular, it makes it possible to add post-translational modifications to the newly synthesized proteins.

Air moves from higher pressure to lower pressure which causes the wind to flow in a particular direction.

Air density variations, which are connected to temperature, are what is causing this shift in pressure which creates a particular difference in air pressure gradient.

Because warm air's gas molecules move faster and further apart than those in cooler air, warm air is less dense than cooler air.

Air density has a direct relationship to pressure, and changes in temperature, humidity, and rising or sinking air are the main factors influencing air density.

Therefore air density is related to pressure so it moves from higher pressure to lower pressure.

Changes in air density cause differences in air pressure.

Cold air is denser than warm air because gas molecules are at lower velocities and are compact to each other in cold air. Air flowing from high-pressure to low-pressure zone forms winds. Air density increases when the temperature is constant and pressure increases.

Similarly, if the temperature increases and pressure is constant the density will decrease. A 3% increase in temperature can decrease air density by 1%.

Thus, change in temperature and pressure can cause changes in air density which can cause differences in air pressure.

convex lens

A convex lens is thinner at the edges and thicker towards the center.

It spreads light rays apart producing an image smaller than the actual object. Nearsighted people (people who see close objects fine but distant objects appear blurry) have concave lenses in their glasses to correct their vision.

Convex lens is the right answer since it is thicker in the center while concave is thinner in the center

Answer: Energy stored in plants is transferred to humans and animals that eat them.

Biosphere is a sphere on earth where living organism forms a biotic community. It is the sum of all the ecosystems. Various life processes occurring in a biosphere are dependent on other spheres on earth that are lithosphere (rocks), hydrosphere (water) and atmosphere (air). In biosphere living beings interact and fulfill their energy requirements.

Energy stored in plants is transferred to humans and animals that eat them here only biosphere is involved. As, energy produced by plants which is a living component of the ecosystem through photosynthesis is transferred to other living components of the ecosystem that are humans and animals. Therefore, only one sphere is involved in this process.

Answer:

The correct option is d. Energy stored in plants is transferred to humans and animals that eat them

Explanation:

Hello!

We will answer that!

We can divide the ecosystem into different parts: hydrosphere, it is the part that contains water; the atmosphere is the part that is the air; the lithosphere is the part that has the rocks; The biosphere is the earth and where the living beings are.

In the ecosystem, all parts coexist, help each other and connect.

Let's analyze all the options:

Plant roots take in water from the soil: in this option two parts act, the biosphere and the hydrosphere

Plants take in carbon dioxide from the air: in this option two parts act, the biosphere and the atmosphere

During photosynthesis, plants make food and release oxygen into the air: in this option two parts act, the biosphere and the atmosphere

Energy stored in plants is transferred to humans and animals that eat them: in this option they act only a part that is the biosphere

After the analysis, we conclude that the correct option is d. Energy stored in plants is transferred to humans and animals that eat them

2NH3 is equivalent to N2 + H6 since the 2 at the beginning gets distributed to both atoms. Knowing this you can rewite the equation as

H2 + N2 = H6 + N2

The N2 can cancel out leaving

H2 = H6

You now have to ask ‘2 times what equals 6?’ The answer is obviously 3 at this point.

Answer: C. 3

To balance the reaction H2 + N2 → 2 NH3, a coefficient of 3 should be placed in front of H2.

In the reaction H2 + N2 → 2 NH3, to balance the reaction, you need to equalize the number of atoms of each element on both sides. There are two nitrogen (N) atoms on the right side, so we need to place a 3 in front of N2 to balance the equation. This means there will be six hydrogen (H) atoms on the right side, so we need to place a 3 in front of H2 to have six hydrogen atoms on both sides. Therefore, the coefficient that should be placed in front of H2 to balance the reaction is 3.

#SPJ11

The coefficient to place in front of H2 to balance this reaction is 3. This ensures there are equal numbers of nitrogen and hydrogen atoms on both sides of the equation.

The question pertains to the balancing of a chemical equation, specifically the Haber process, which is the creation of ammonia (NH3) from hydrogen (H2) and nitrogen (N2). According to the chemical equation, we can see that there are two nitrogen atoms and six hydrogen atoms on the right side (2 NH3), while on the left, we've only got two hydrogen atoms (H2) and one nitrogen atom (N2). So to balance it, we need three molecules of hydrogen (giving us 6 hydrogen atoms) per one molecule of nitrogen. Therefore, to balance the reaction, the correct coefficient to place in front of H2 is 3.

So the correctly balanced reaction will be 3 H2 + N2 ----> 2 NH3.

The plasma membrane is what allows things in and out of the cell. It has phospholipids and microvilli on it.

The plasma membrane, also known as the cell membrane, is a selective barrier that surrounds the cytoplasm of a cell, separating the cell's internal environment from the external environment. It is primarily composed of a double layer of phospholipids, which forms a lipid bilayer, with embedded proteins, cholesterol, and carbohydrates attached to some of the lipids and proteins.

Structure of the Plasma Membrane:

1. Phospholipid Bilayer: The bilayer consists of two layers of phospholipids arranged in an antiparallel fashion. Each phospholipid molecule has a hydrophilic (water-attracting) head and two hydrophobic (water-repelling) tails. The hydrophilic heads face outward, towards the aqueous environment inside and outside the cell, while the hydrophobic tails face inward, away from the water. This arrangement creates a stable barrier that is selectively permeable.

2. Membrane Proteins: These are embedded within or associated with the lipid bilayer. They can be classified into two types:

 - Integral Proteins: These are permanently anchored in the membrane and may span the entire width of the bilayer. They can function as channels, transporters, receptors, or enzymes.

 - Peripheral Proteins: These are temporarily associated with the membrane, either with the lipid bilayer or with integral proteins. They are found on the inner or outer surface of the membrane and are involved in signaling pathways or provide structural support.

3. Cholesterol: Found among the phospholipid molecules, cholesterol helps to maintain the fluidity of the membrane, making it less viscous at low temperatures and preventing it from becoming too fluid at high temperatures.

4. Carbohydrates: Attached to some lipids and proteins on the outer surface of the membrane, carbohydrates play a role in cell recognition, cell signaling, and the formation of the extracellular matrix.

Functions of the Plasma Membrane:

1. Selective Permeability: The plasma membrane allows certain substances to pass through while blocking others. Small, nonpolar molecules can diffuse across the lipid bilayer, while ions and polar molecules require the assistance of membrane proteins to cross.

2. Transport: Membrane proteins facilitate the movement of substances across the membrane either down their concentration gradient (passive transport) or against their concentration gradient (active transport).

3. Cell Recognition and Communication: Glycoproteins and glycolipids on the cell surface serve as markers that allow cells to recognize each other. This is crucial for processes such as immune response and cell signaling.

4. Signal Transduction: Membrane proteins, particularly receptors, play a key role in converting external signals into cellular responses. This process is known as signal transduction.

5. Enzymatic Activity: Some integral proteins have enzymatic functions, catalyzing reactions at the membrane surface.

6. Cell Adhesion: Certain membrane proteins mediate cell-to-cell adhesion, which is important for maintaining the structure of tissues.

7. Energy Transformation: In some cells, such as those in the mitochondria and chloroplasts, membrane proteins are involved in the conversion of energy, such as during photosynthesis and cellular respiration.

In summary, the plasma membrane is a dynamic structure that serves as a protective barrier, regulates the movement of substances into and out of the cell, and plays a critical role in cellular communication and adhesion. Membrane proteins are integral to these functions, facilitating transport, signaling, and many other cellular processes.
