How many carbon-carbon bonds does pyruvate have? How many carbon-carbon bonds does acetyl-CoA have?

Answers

Acetyl CoA contains one carbon carbon bond compared to Pyruvate's three

One glucose molecule undergoes glycolysis to produce two molecules of pyruvic acid with three carbons each.

Acetyl coenzyme A and carbon dioxide are produced by the acetylation and decarboxylation of each of these pyruvate molecules.

Acetyl CoA molecules therefore have two carbon atoms per unit.

Coenzyme A is an essential component of this process, which turns a NAD+ molecule into NADH and releases a carbon dioxide molecule.

The oxidative decarboxylation of pyruvate by the mitochondrial pyruvate dehydrogenase complex results in acetyl-CoA, a two-carbon acetyl unit ligated to the acyl-group carrier CoA.

Explain the ages of crustal rock using evidence of the past and current movements of continental and oceanic crust and the theory of plate tectonics.

Answers

The age of crustal rocks can be determined by the help of plate tectonics as the oldest rocks move away and deeper into the ridge.

How to determine age of crustal rocks?

Crustal rocks or Continental crust is the layer of igneous, sedimentary, and metamorphic rocks which are formed by the geological continents and the areas of shallow seabed that are close to their shores which is known as continental shelves.

The surface of continental crust mainly lies above the sea level, its existence allowed the land life to evolve from the marine life. Its existence can also provide broad expanses of shallow water known as epeiric seas and the continental shelves where complex metazoan life could become established during the early Paleozoic period, which is now called as the Cambrian explosion.

By using the magnetic polarity of the sea floor the age of crust rocks can be determined. Very little of the sea floor is older than 150 million years. This is because the oldest sea floor is subducted under other plates and replaces by new surfaces. Thus, the plate tectonics can help in determining the age of crustal rocks.

How might the variety of traits affect the survival of the ladybugs?

Answers

Answer:

The variety of traits may cause the species of ladybugs to divert. Over time, if certain ladybugs were more adept at surviving on a certain plant or a different place, those ladybugs might survive, while others don't.

Another example is internal traits. For example, if pesticides that killed ladybugs were sprayed and there were some ladybugs that were resistant to it, more of those ladybugs would survive to reproduce.

Another impact could be the physical characteristics of the species. For example if there were yellow ladybugs and red ladybugs, and birds could see the yellow ladybugs better, since birds are predators of ladybugs, they could eat more of the red ladybugs. As a result, more red ladybugs would survive to pass on the gene that makes them red colored.

These are some examples. Hope this helps!

There is a solid, light brown mass at the bottom of the pot. It has a mass of 100 grams. The mass of the sugar is the same in melted form as it is in solid crystal form. There was not a chemical reaction. Sugar did not change composition. It only melted. Melting point is a physical property, and this is a physical change.

Steel Wool + Oxygen (Fire): chemical change

Egg + Heat: chemical change

Water + Heat: physical change.

Zinc + Hydrogen Chloride: chemical change

Sodium Hydroxide + Copper Sulfate: physical change

What is conservation of mass?

According to the rule of conservation of mass, no atoms are lost or created during a chemical process. Instead, the atoms combine in various ways to generate products. This is why the number of atoms in each element in a balanced symbol equation is the same on both sides of the equation.

Steel Wool + Oxygen (Fire):

The steel wool is a grayish color and has a rough surface. Oxygen is transparent  It looks like a powder, and like if it was rusted steel wool but then broken apart and turned into a powder  Well Iron oxide is 7 grams and steel wool combined is 7 grams so that the mass was conserved  Yes, this is a chemical change because the steel wool rusted and rust is a chemical change, so iron oxide is cause because if a physical change.

Egg + Heat:

The egg has a yellow yolk in the middle while there is some type of liquid at the border of the yolk, but it is clear, the heat is hot but transparent  The egg turned into a delicious food called an omelet what was yolk staid as a liquid but got a tad harder, but the transparent border around it turned white  It was conserved because the eggshell was 4 grams and the fried egg is 41 grams  It is a chemical change because it results in the formation of new particles, and the chemical bonds break up and new ones are formed.

Water (H₂O) + Heat:

The water is a clear liquid, while the heat is very hot but transparent  The water turned into a type of oxygen -Water Vapor-   If 5 g of water becomes a gas it becomes 5 g of water vapor. The mass of the liquid water is simply transferred into the mass of the newly formed water vapor.  There was no chemical reaction because the water vapor can be turned back to water also it just changed from a liquid to a gas and did not change its composition. So, it is a physical change.

Zinc (Zn) + Hydrogen Chloride (HCl):

 Zinc: a white/silver metallic solid. Hydrogen chloride (dilute hydroelectric acid) a transparent, colorless liquid with a very low pH (acidic). Zinc "dissolved" in hydrogen chloride, while emitting a colorless gas.  The liquid remains a colorless liquid, possibly still having a low pH from the unused acid. The colorless gas collected in a test tube gives a popping sound when ignited with a burning wooden splint, so it is not air embedded in the zinc, nor dissolved in hydroelectric acid.  Well although the zinc chloride is 12 grams and not 15 the gas that was released was 3 grams and as we all know 3 + 12 is 15 so that the mass was conserved The production of a new substance (most probably hydrogen) from the reaction of the two reactants. When a few drops of the liquid product are evaporated on a watch glass, a white residue is left.  When a few drops of the liquid hydroelectric acid are evaporated on a watch glass, there is no residue. This proves that a new product (hydrogen gas), (white powder, zinc chloride) is produced instead of zinc being physically dissolved in hydroelectric acid. So, it is a chemical change.

Sodium Hydroxide + Copper Sulfate-

 Sodium hydroxide is a turbid solution and copper sulfate is in form of bright blue crystals. When their solutions are mixed with each other, a pale blue precipitate of basic copper hydroxide & a solution of neutral salt sodium sulfate will be formed. The sodium hydroxide and the copper sulfate combined make a total of 67 grams and the product  is split because the sodium sulfate is 47 grams and the copper hydroxide is 20 grams but all together it is still 67 grams so you could say that the mass was conserved. The proof of the reaction is the appearance of pale blue precipitates of basic copper hydroxide & a solution of neutral salt sodium sulfate. So, it is physical change.

Answers

There are five major types of biomes: aquatic, grassland, forest, desert, and tundra, though some of these biomes can be further divided into more specific categories, such as freshwater, marine, savanna, tropical rainforest, temperate rainforest, and taiga

Define a biome.

A biome is a biogeographical unit made up of a biological community that has developed in response to the physical environment in which it is situated and a common local climate. Many different continents have different biomes. Different habitats can be included in a biome, which is a more general phrase than habitat.

Of all the terrestrial biomes, tropical forests have the highest primary productivity and biodiversity. Large-scale photosynthetic output and rapid growth are encouraged by the physical environment.

As a result of rapid decomposition, the nutrient supply is at its highest in rain forests, where plants are always exposed to high levels of water and light (at the canopy level). The light can support the growth of multiple layers of plants because it is so powerful. When there is a lot of water available, plants can continuously release nutrients from their roots. Without running out of water, they can keep their stomata open all day to maximize CO2 absorption. If necessary, they can use water to cool off. Rapid enzyme activity without seasonal dormancy is made possible by high and constant temperatures.

Due to wind-induced desiccation and stem bending that results in ice damage, tundra and alpine environments do not allow for very tall plant growth. This implies that there may be fewer layers of vegetation and less effective light absorption. The rate at which enzymes can catalyze reactions slows down in cold weather, which restricts NPP. Biochemistry cannot occur when water is frozen. The soil nutrients may be permanently locked up in frozen soil even when the air temperatures rise enough to permit photosynthesis.

Deserts are places with little accessible water. Extreme deserts, whether they are hot or cold, lack water, which makes it difficult for most plants to survive. As a result, productivity is very low. In both environments, plants may exhibit similar adaptations to conserve water.
