If ingested how toxic is lye in a finished soap product?

Lye itself is caustic and can cause burns or irritation if ingested. In a finished soap product, lye is typically fully reacted with oils during the soap-making process, reducing its caustic properties. However, ingesting a large amount of soap could still lead to gastrointestinal issues or discomfort.

If the low coollant level light is on what is wrong?

The low coolant level light turning on suggests that there might be a leak in the cooling system causing loss of coolant. It is important to check the coolant level, top it up if necessary, and inspect the system for any leaks to avoid potential overheating issues.

How do plants survive in dark places?

Plants can survive in dark places through a process called etiolation, where they grow tall and thin to reach for light. They may also adapt by increasing their chlorophyll content to maximize light absorption, and by storing energy reserves to sustain themselves. However, prolonged lack of light can weaken plants and inhibit their growth and development.

What abiotic factor influences on photosynthesis?

Light intensity is a key abiotic factor that influences photosynthesis. Higher light intensity generally leads to increased photosynthetic activity, as it provides energy for the process. However, excessive light can also damage the photosynthetic machinery.

Why are green plants important to us?

Green plants are important to us because they produce oxygen through the process of photosynthesis, which is essential for the survival of all living organisms. They also provide food and habitat for animals, help to regulate the climate by absorbing carbon dioxide, and contribute to the overall biodiversity and health of ecosystems.

What is Krebs cycle?

The Krebs cycle is a cycle that is after glycolysis which allows the cell to get more ATP and have more ATP efficiency than that of glycolysis itself or fermentation and glycolysis. Infact, it makes the ATP effeciency about 20 times of glycolysis itself!

Here is the Krebs cycle:

Step 1: The acetyl CoA (a two carbon) joins with oxaloacetic acid (a four carbon). The CoA (Coenzyme A) is returned back to the mitochondira. The result is a six carbon called citric acid.

Step 2: The citric acid gives off carbon dioxide and gives a hydrogen ion (H+) to NAD+ resulting in NADH. Since the citric acid gave off a carbon in the form of CO2, (carbon dioxide) it is now a 5-carbon molecule.

Step 3: The 5-carbon molecule then gives off CO2 once again, gives a hydrogen ion(H+) to NAD+ resulting in NADH, and in this process, phosphate joins with ADP to create ATP. The resulting molecule is a 4-carbon.

Step 4: The 4-carbon molecule gives a hydrogen ion (H+) to FAD (similar to NAD), which results to FADH2.

Step 5: The 4-carbon molecule once again gives off H+ to NAD resulting into NADH. The 4-carbon molecule is then known as oxaloacetic acid, and the cycle begins again.

Remember:glycolysis produces 2 pyruvic acid molecules, which produces 2 acetyl CoA molecules (and 2 NADH), which means that for every molecule of glucose, the Krebs cycle happens twice.

The resulting amounts of NADH and FADH2 go through the electron transport chain and the enzyme ATP synthase to produce a waste of water, ATP molecules, and a restoration of the NADH to NAD+ and the FADH2 to FAD+ so that they can be used again in the Krebs cycle.

Waste products of photosynthesis?

The waste products of photosynthesis are oxygen and water vapor. During photosynthesis, plants take in carbon dioxide and water to produce glucose and oxygen as byproducts. The oxygen is released into the atmosphere, while water vapor is also expelled through transpiration.

Why is respiration important?

Respiration is important because it is the process through which cells obtain energy from glucose molecules. This energy is essential for all cellular activities, such as growth, repair, and maintenance of the body. Without respiration, cells would not be able to function and the body would not be able to survive.

What is another name for the Krebs cycle?

Tricarboxylic acid cycle, the citric acid cycle, and the Szent-Györgyi-Krebs cycle

How do you make a moss pole for a monstera plant?

you can buy coco fibre mat or burlap, and then get a piece of plastic (pvc) tubing about 2" or more in diameter. Drill holes in the tubing for aereation. Wrap the mat around the tube, securing with wire or zip-ties, and use it as a stake. Start by tying the plant to it. Keep the post moist by spraying. Eventually the air roots with cling and the plant will grow up the pole. If you spray the Monstera at the rate with a moss pole you don't need a moss pole it is simply decoration.

What are the most important parts of communication?

The way it is said.

The listener.

The environment in place. (Coworker, boss, spouse, child. These are all separate environments and require separate communication structures)

The actions of the speaker before, during and after communication takes place.

The ability of the receiver to understand what is said.

Essentially:

Language, body language, listening, and understanding.

Which portion of the electromagnetic spectrum is used to identify fluorescent minerals?

Ultraviolet (UV) light is used to identify fluorescent minerals. Specifically, shortwave ultraviolet (UV-C) and longwave ultraviolet (UV-A) light are commonly used in mineral identification due to their ability to cause fluorescence in certain minerals when exposed to them.

Reactants and products?

The substances used up in a reaction are the reactants. The new substances made are called the products. The terms reactant and product can be used to describe constituents of individual enzymatic reactions or entire metabolic pathways. Reactants (or 'substrates') are the starting materials for a reaction, In the generic reaction shown below, A and B are the reactants. C and D are the products. http://www.marietta.edu/~spilatrs/biol103/photolab/reaction.html image reference

How does a plant make its own food?

Plants make their own food through a process called photosynthesis. They use sunlight, water, and carbon dioxide to produce glucose (sugar) and oxygen. Photosynthesis occurs in the chloroplasts of plant cells, where chlorophyll, a green pigment, captures sunlight energy to drive the chemical reactions that convert carbon dioxide and water into glucose.

How long does it take for a plant to make its own food?

Plants can start producing their own food through photosynthesis within days to weeks after germination, depending on factors like species, environmental conditions, and access to sunlight. The process involves capturing light energy and converting it into chemical energy stored in the form of sugars.

Second step in photosynthesis?

The second step in photosynthesis is the light-dependent reactions, which take place in the thylakoid membranes of the chloroplasts. During this step, light energy is absorbed by chlorophyll and water molecules are split, releasing oxygen as a byproduct. This process generates ATP and NADPH, which are used in the Calvin cycle to produce glucose.

What is the study of plants?

The study of plants is called botany, the person who studies plants is called a botanist. Botany is a field of Life Sciences which looks at the classification and physical characteristics of plants.

A person who studies the interaction of plants and animals in an environment is called an ecologist or environmentalist.

A person who grows plants is called a horticulturist.

Is there anywhere you can still get acuvue 1 day colors in green - discontinued but surely there must be old stock somewhere?

The best way to find that out is by calling optometrist offices. I have worked for eye doctors before and they normally have contacts in stock and if they don't they work hand in hand with the people who supply them with contacts. Or you should try to google acuve find a number and call them. Hope I was able to help you.

I would think that because they are discontinued, any remaining boxes would have to be checked for their expiration dates. If you are willing to change brands, Ciba Vision make one-day lenses in green. Freshlook one day and I found these here www.ow.ly/14h2R for $14.75/box of ten lenses.

How do plants use sunlight?

because their need to grow

because their need to grow

You're mean.

its called photosynthesis and the plant uses the energy from the sun and turns it into carbohydrates (:

hahah im a nerd (:

hi (:

What are the processes involved in photosynthesis?

Processes involved in photosynthesis: # Roots absorb water from the soil. # Water is transported from the roots to the leaves by the stem. # Chlorophyll in the leaves capture sunlight to act on water. # Oxygen and moisture are given off to the air. # Carbon dioxide enters the leaves through the stomata. # Carbon dioxide combines with a substance in the cell, eventually producing a kind of sugar (I think it's glucose). # The sugar (dissolved in water) is transported from the leaves to the different parts of the plant. # Once the sugar reaches the different parts of the plant body, it may be used up by the cells. Or it may be converted into starch and stored for future use. Well, that's all, nothing else, at least, not that I know of. Heehee...^_^

How is a gulf of water formed?

A gulf of water is formed when land sinks or when sea levels rise, resulting in a large body of water surrounded by land on three sides. This geological process usually occurs over long periods of time due to tectonic movements or changes in sea level.

Does photosynthesis occur at night?

Light is essential for photosynthesis to occur because it is the source of energy, so it doesnt occur during the night. However, CAM plants have the capability to run the light reactions during the day (when there is light) and the Calvin cycle at night. They do this by only opening their stomata at night and allowing the gas exchange then. This is done as a way to reduce the effects of transpiration in dry climates.

What are the different raw materials?

Raw materials: glucose and oxygen

Products: carbon dioxide and water

And, of course, energy.
