  • by

The candle in jar a is likely to produce less soot because it has a narrower opening. This allows for less air to flow into the jar and mix with the flame, which reduces the amount of soot that is produced.

When you light a candle, the air around the flame heats up and starts to rise. This process is called convection. The hot air rises and escapes out of the jar, while cooler air rushes in to take its place.

This causes a draft that can extinguish your candle. To avoid this problem, make sure the jar you use is large enough so that the flame isn’t close to the sides of the jar. You can also try covering the jar with a glass plate or lid to help keep the heat in.

Which Letter Points to the Structure Through Which Water is Lost During Transpiration?

Water is necessary for plants to grow, but too much water can be just as harmful as not enough. Water lost through transpiration helps regulate a plant’s water intake and prevent it from becoming overwatered. But which letter points to the structure through which water is lost during transpiration?

The answer might surprise you: it’s actually the leaf! Leaves are covered in tiny pores called stomata, and it is through these stomata that water vapor escapes from the plant. When the air around a plant is dry, the stomata will close up to prevent further water loss.

However, when the air is humid, the stomata will open wider in order to allow more evaporation and help keep the plant cool. So there you have it: the next time you’re wondering which letter points to the structure through which water is lost during transpiration, just think of L-E-A-F!

Which of the Following is Not a Step in the Light-Dependent Reactions?

In the light-dependent reactions of photosynthesis, energy from sunlight is used to convert water and carbon dioxide into oxygen and glucose. These reactions occur in the chloroplasts of plants and algae. There are four main steps in the light-dependent reactions:

1. Light hits the pigment molecules in the thylakoid membrane, exciting electrons and causing them to move around. 2. The excited electrons are passed down an electron transport chain (ETC), which pumps protons (H+) across the thylakoid membrane into the stroma. This creates a proton gradient that is used to generate ATP from ADP + Pi using chemiosmosis.

3. Oxygen is produced as a by-product of this process when water is split by H+ ions that have been pumped across the thylakoid membrane.

Where Do the Light-Dependent Reactions Take Place?

The light-dependent reactions of photosynthesis take place on the thylakoid membranes. These are flattened sacs that are found in chloroplasts, which are organelles that are unique to plant cells. Within the thylakoid membrane is a stack of disks called grana.

It is within the grana that the light-dependent reactions occur. When a photon (a particle of light) hits a pigment molecule, such as chlorophyll, it causes an electron to be excited to a higher energy level. This energy can then be used to power the synthesis of ATP (adenosine triphosphate), which is an important energy storage molecule in cells.

The light-dependent reactions also produce NADPH (nicotinamide adenine dinucleotide phosphate), which provides reducing power for use in the Calvin cycle (the second stage of photosynthesis).

Which of the Following Activities Happens within the Stroma?

The stroma is the fluid-filled area between the lens and the retina of the eye. It helps to keep the lens in place and provides nourishment to the eye. The following activities happen within the stroma:

The ciliary body produces aqueous humor, which fills the stroma and helps to maintain its shape. The aqueous humor also provides nutrients to the lens and retina. The iris regulates the amount of light that enters the eye by expanding or contracting.

This helps to protect the retina from damage caused by too much light. The choroid is a layer of tissue that lines the back of the eye. It contains blood vessels that provide oxygen and nutrients to the retina.

Photosynthesis Uses Sunlight to Convert Water And Carbon Dioxide into

Photosynthesis is a process that uses sunlight to convert water and carbon dioxide into oxygen and glucose. The process of photosynthesis occurs in the chloroplasts, which are organelles found in the cells of plants. In order for photosynthesis to occur, there must be light, water, and carbon dioxide present.

The light energy is used to split the water molecules into hydrogen and oxygen atoms. The hydrogen atoms are then used to combine with the carbon dioxide molecules to form glucose molecules. The oxygen atoms are released as a by-product of this reaction.

The process of photosynthesis is essential for life on Earth as it produces the oxygen that we breathe and the food that we eat. Plants are able to produce more glucose than they need for their own growth and metabolism, so they serve as a source of food for other organisms. Photosynthesis also helps to regulate the levels of atmospheric carbon dioxide, which helps to keep our planet hospitable for life.

Atp Synthase Changes Adp to Atp When Light Energy Passes Through It.

ATP synthase is an enzyme that changes ADP to ATP when light energy passes through it. This process is known as photophosphorylation. ATP synthase consists of two parts: a light-sensitive electron transport chain and a catalytic site.

The electron transport chain transfers electrons from one molecule of NADPH to another molecule of NADPH, which then passes the electrons to the catalytic site. The catalytic site uses the energy from the electrons to synthesis ATP from ADP.

In Which Experimental Setup Shown above Would You Expect the Elodea Plant

If you were to set up an experiment like the one shown in the image above, which experimental setup would you expect the Elodea plant to do better in – A or B? Why? If you were looking at just the plants themselves, you might expect that Plant A would do better because it has more leaves and seems to be a healthier plant overall.

However, when you take into account the fact that Plant B is receiving direct sunlight while Plant A is not, it’s clear that Plant B is actually going to fare better in this experiment. Plants need sunlight to photosynthesize and produce food for themselves. Since Elodea are aquatic plants, they get their nutrients from the water around them.

When there’s no sunlight available, as in Plant A’s setup, the Elodea isn’t able to produce its own food and will eventually start to decline. In contrast, Plant B is receiving plenty of sunlight and will be able to thrive. So if you were conducting this experiment, you would expect Plant B to do better than Plant A. But what happens if we add another variable into the mix?

What if we introduce a third plant, C, that is also receiving direct sunlight but has its leaves covered so that only indirect light can reach them? In this case, we would expect Plant C to do worse than both Plants A and B. Even though it’s receiving some sunlight, it’s not enough for photosynthesis to occur properly. The leaves being covered also blocks out some of the light that could potentially reach them, further hindering photosynthesis.

As a result, we would expect Plant C to have less growth than either of the other two plants over time.

Which Gas is Likely to Be Reduced in the Atmosphere by Deforestation

Anthropogenic activities, such as deforestation, can lead to a decrease in atmospheric concentrations of certain gases. In the case of deforestation, the gas most likely to be reduced in concentration is carbon dioxide (CO2). This is because trees take up CO2 from the atmosphere and store it in their leaves, stems, and roots.

When trees are cut down and burned or left to decompose, this stored CO2 is released back into the atmosphere. Thus, deforestation can cause an increase in atmospheric CO2 levels. Other gases that may be affected by deforestation include water vapor and methane (CH4).

Which Structure in Figure 8 2 Represents a Single Thylakoid?

In Figure 8-2, the structure on the left represents a single thylakoid. This is evident from the fact that it is surrounded by a membrane, which is characteristic of thylakoids. In addition, this structure contains chloroplasts, which are also found in thylakoids.

What Would You Expect If You Deprived a Plant of Co2?

If you deprived a plant of CO2, it would slowly die. Plants need CO2 for photosynthesis, which is how they make their food. Without CO2, plants would not be able to make food and would eventually die.

How Does Photosynthesis Use Sunlight to Convert Water And Carbon Dioxide Into?

Photosynthesis is the process that produces organic molecules from simple inorganic molecules from the sun’s energy. In order to carry out photosynthesis, plants need three things: water, carbon dioxide and sunlight. Water is used as a solvent in which all the necessary chemical reactions take place.

Carbon dioxide is used as an reactant in photosynthesis, and it is also one of the products of respiration (a process that happens at night). Sunlight provides the energy needed to drive the chemical reactions of photosynthesis. The first step of photosynthesis is called light interference.

Light interference occurs when plant pigments absorb photons from sunlight. The plant pigment that is most important for light interference is chlorophyll. Chlorophyll absorbs all wavelengths of visible light except green, which it reflects back (hence why leaves look green).

The energy from the absorbed photons excites electrons within the chlorophyll molecule to a higher energy state. The next step of photosynthesis is called carbon fixation. In carbon fixation, enzymes within the chloroplasts convert carbon dioxide into organic molecules such as glucose (C6H12O6).

This process requires ATP and NADPH, both of which are produced during light interference. The ATP powers the enzymes while NADPH provides electrons to make sure that enough reduction power exists to reduce CO2 into glucose This makes up what we call Calvin cycle .

Calvin cycle happens inside stroma ,which are fluid-filled spaces outside thylakoids .In this stage ,the 3-carbon molecules goes through seriesof biochemical reaction catalyzed by enzymes until it formsG3P(glyceraldehyde 3-phosphate)molecules . Some G3Pmolecules exitsthe Calvincycle and become building blocks for other biomolecules like amino acids or lipids .

What Would You Expect to Happen to Plants at Temperature Greater Than 45?

If the temperature is greater than 45 degrees, the plant will wilt. The leaves will droop and the stem will bend. The plant will stop growing and eventually die.


Appear to Grow in Length The author starts off by asking why the candle in jar A might appear to grow in length. They then go on to explain that it is due to the air inside the jar being heated up by the flame of the candle.

This causes the air to expand and push against the sides of the jar, making the candle appear longer.
