Answers
Answer:
I think it is Chemical reactions produce glucose, ADP and NADPH
Explanation:
Photosynthesis is a chemical reaction that takes place to convert light energy. The photosynthetic light-dependent reaction forms glucose, ATP, and NADP⁺. Thus, option A is correct.
What is a light-dependent reaction?
A light-dependent reaction is a photosynthetic reaction that occurs in the presence of sunlight and produces chemical energy in the form of NADPH and ATP.
The products of the photosynthetic light-dependent reaction are used in light-independent reactions. In light-dependent, the photosystem gets excited and produces ATP from ETC, leading to reduction of NADP⁺ and photolysis of the water molecule.
Therefore, ADP and NADP+ are produced at the intermediary stage of the light-dependent reaction which makes them different from the light-independent reaction.

what is the cell wall function and factory part or worker?
Answers
Answer:
Major cell parts function just like the structures and people who work together in a factory. Cells have strong cell walls and a cytoskeleton to keep their shape; the walls are made of fiber for protection just like a factory building has sturdy walls for support.
The cell wall serves as a protective and structural layer surrounding plant, fungal, and bacterial cells. It provides rigidity, support, and defense against external pressures and pathogens.
In various species, the cell wall serves as a robust outer layer. Its primary component in plants is cellulose, which helps to preserve cell structure, limit excessive water absorption, and promote growth. Chitin is found in the cell wall of fungi, providing both structural integrity and protection.
Bacteria have a variety of cell wall compositions; peptidoglycan, for example, is an essential part of many bacterial cell walls. Along with other cellular components, this "factory-like" part of the cell performs its functions. It is comparable to a factory's base, supporting the cell's framework, and worker, guarding against threats and preserving the cell's overall operation.

Under which conditions would air hold less water vapor than it holds at 30°C
(86°F) with sunny skies?
A. 34°C (94°F) with cloudy skies
B. 30°C (86°F) with cloudy skies
C. 22°C (86°F) with sunny skies
D. 32°C (90°F) with sunny skies
Answers
Answer:
B
Explanation:
jus CS its right
The relative humidity of the air affects how much water vapor it can hold. 30°C (86°F) with cloudy skies would air hold less water vapor than it holds at 30°C (86°F) with sunny skies. So, the correct option is B.
What is Relative humidity?Relative humidity (RH) measures the amount of moisture in the air compared to the maximum amount of moisture in the air at a given temperature and pressure. It is a standard figure for describing the moisture content of the air and is expressed as a percentage.
At a given temperature and pressure, air is considered to have 100% relative humidity when it contains all the moisture it can hold. The temperature at which the moisture in the air begins to condense into droplets is known as the dew point.
Therefore, the correct option is B.

Which mechanism allows lipid-soluble substances to move through the membranes of endothelial cells of capillaries
Answers
Answer:
Diffusion.
Explanation:
The mechanism that allows lipid-soluble substances to move through the membranes of endothelial cells of capillaries is simple diffusion.
Simple diffusion is a passive transport mechanism that allows lipid-soluble substances to move across the membranes of endothelial cells in capillaries. This process occurs down a concentration gradient, from an area of higher concentration to an area of lower concentration, without the need for energy expenditure.
The membranes of endothelial cells, which make up the walls of capillaries, are composed of a lipid bilayer. Lipid-soluble substances, such as oxygen, carbon dioxide, steroid hormones, and certain lipid-soluble drugs, can readily diffuse through this lipid bilayer due to their ability to dissolve in and pass through the hydrophobic interior of the membrane.
Unlike lipid-soluble substances, water-soluble substances, such as ions and polar molecules, are unable to passively diffuse through the lipid bilayer. Instead, they rely on specific transport mechanisms such as facilitated diffusion or active transport to cross the endothelial cell membrane.
In the context of capillaries, simple diffusion allows lipid-soluble substances to move from the bloodstream through the endothelial cell membranes and into surrounding tissues or vice versa. This process plays a crucial role in the exchange of gases, nutrients, and waste products between the bloodstream and the tissues.
It is important to note that while simple diffusion allows for the passage of lipid-soluble substances, the movement of these substances can also be influenced by factors such as concentration gradients, molecular size, solubility, and the presence of transport proteins. However, the primary mechanism by which lipid-soluble substances traverse the endothelial cell membranes of capillaries is through simple diffusion.

O Carbon dioxido helps animals make proteins.
Carbon dioxide forms clouds that produce rain
Answers
Answer:Plants use carbon dioxide to make food
Explanation: Carbon-dioxide plays a very important role in sustaining life on Earth.
Plants use carbon-dioxide and water for photosynthesis in presence of sunlight and chlorophyll to produce food and oxygen.
CO₂ + H₂O → O₂ + glucose (food)
This food is consumed by the animals and oxygen is used for respiration. Animals use energy from the food to do work and exhale back carbon-dioxide.

Explanation:
Mitosis is the only type of cellular division in which number of chromosomes is maintained
What is mitosis?During the phase of the cell cycle known as mitosis, duplicated chromosomes are physically split in half to form two new nuclei. Mitosis is a method of cell division that results in the production of cells that are genetically similar and in which the total number of chromosomes is preserved. Since this occurs during mitosis, the process is often referred to as equational division.
Mitosis serves a very vital purpose in living creatures, and one of its functions is the regeneration and replacement of worn-out and damaged tissues. Mitosis contributes to the generation of identical copies of cells and, as a result, assists in the process of healing damaged tissue or replacing cells that have been worn out.

Explain how homologous structures are used as a source of evidence to infer evolutionary relationships between modern and fossil organisms
Answers
Answer:
Homologous structures provide evidence for common ancestry, while analogous structures show that similar selective pressures can produce similar adaptations.
Explanation:
Analogous structures demonstrate that identical selective pressures might result in similar adaptations, whereas homologous structures indicate evidence for shared ancestry.
What are analogous structures?In contrast to homologous structures, analogous structures are characteristics of different species that have evolved in response to a similar environmental challenge and are similar in function but not necessarily in structure.
While comparable structures demonstrate that similar selective pressures can result in similar adaptations, homologous structures suggest that they have a common ancestor (beneficial features).
Therefore, homologous structures provide evidence for common ancestry, while analogous structures show that similar selective pressures can produce similar adaptations.

CAN SOMEONE WHO DID THE CELERY STALK OSMOSIS LAB ANSWER THESE QUESTIONS? 50 POINTS
1. What is osmosis?
2. Celery is composed of millions of plant cells. Do these cells contain any water?
Yes
3. Did the cut celery in step 8 & 9 show any color change that would indicate that the water did enter the celery cells?
4. If you placed the celery into a bottle of colored water that was 35% sugar, would the colored water be seen in the celery? Why or why not? (HINT: Drawing a diagram of this scenario may help – 35% sugar is a very concentrated solution…)
Answers
Answer:
1. 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.
2. Plants obtain water through their roots. Water present in the soil (or air, in the case of air plants) enters the plant through the epidermis of the root. The epidermis is a very thin single layer of cells. The water passes through the membranes of plant cells and also fills the spaces in between the cells.
3. This experiment allows you and your child to talk about the circulatory system and "capillary" action. The small "vessels" in the celery stalks carry the water and color to the leaves, like the way blood travels through your body.
4. A great way to introduce basic science concepts are through fun and visual experiments such as this Celery Experiment. It requires just a few items and is a fun way to teach children about how a plant absorbs water. This process is called Osmosis. We will learn about how plants absorb water using colored water and celery stalks.

Which of these changes is a possible negative consequence of farmers

O A. Desertification
O B. Shortage of freshwater
O c. Deforestation
O D. Abundance of clean air
Answers
Given what we know, one of the possible negative consequences of farmers allowing livestock to overgraze a pasture is desertification.
What is Desertification?In simple terms, desertification is when the land becomes so dry and void of life that it can be considered a desert. This can be caused by many factors, primarily the lack of vegetation.How can overgrazing lead to Desertification?Overgrazing can lead to desertification due to the fact that the plants and vegetation are not given the opportunity to regrow.The presence of vegetation allows the soil to remain moist and fertile by moving minerals and water through it. Overgrazing causes a lack of vegetation which creates dry and infertile land, which leads to complete desertification.Therefore, we can confirm that one of the possible negative consequences of farmers allowing livestock to overgraze a pasture is desertification due to the damage caused to the soil in the absence of vegetation.
