Enzymes have an attachment site called the active site for the substrate to join. Consequently, what is catalytic site of enzyme? In biology, the active site is the region of an enzyme where substrate molecules bind and undergo a chemical reaction.

Enzymes have an attachment site called the active site for the substrate to join. Enzymes then convert the substrate into a product and release it from the active site.

The enzyme has an active site where the substrate binds and then forms a noncovalent bond with the enzyme. As a result of this binding, the product is formed by different modifications.

The enzyme has another site apart from the active site, and that is called the allosteric site. This site is occupied by regulators that can regulate the enzyme by enhancing or suppressing the enzyme's activity.

The enzyme is made up of amino acids by the process of translation, but not all enzymes are made up of amino acids. Apart from the polypeptide chain, there are molecules such as zinc, magnesium, etc. at the catalytic site to help enzymes make the product.

Hence, enzymes have an attachment site called the active site for the substrate to join.

Ok so i will try my best to describe the answers:

1) a convection current is like a boiling pot of soup. the burner heats up the soup on the bottom. hot air always goes up because the molecules become more active, making them space out upward. the hot soup travels up through the center of the pot, and the cold soup up top travels down towards the edges of the pot to replace the hot soup that just moved up. the process keeps on going and going until there is no more heat, or until the burner turns off.

2&3) the sun makes everything warmer, so when the sun touches Earth's surface, it warms up the air around it. as soon as the air warms up, it goes up into the atmosphere, like the pot of soup example. then, cold air from the top moves in to replace the hot air. with so many molecules of air moving at one time, it makes gusts of wind during the movement. when it is really windy, that means that there is a lot of hot air moving up and cold air moving down. when there is no wind, that means that every molecule is where it is supposed to be, not disturbing one another.

The Sun's heating of the Earth's surface generates convection currents in the atmosphere. These convection currents, driven by differences in temperature and density, lead to the formation of winds as warm air rises and cooler air sinks.

The combination of convection currents and the Coriolis effect creates the intricate wind patterns and circulation systems that influence weather and climate across the globe.

A convection current is a process of heat transfer that occurs in fluids (liquids or gases) where warmer regions of the fluid rise while cooler regions sink. This phenomenon is driven by differences in temperature and density within the fluid. As a fluid is heated, it becomes less dense and rises, while cooler, denser fluid sinks to replace it. This movement forms a circular pattern known as a convection current.

The Sun plays a crucial role in generating convection currents in Earth's atmosphere. The Sun's energy reaches the Earth primarily in the form of sunlight. When sunlight strikes the Earth's surface, it warms the air close to the surface. Warmer air is lighter and less dense, causing it to rise. As this warm air rises, it creates a region of lower pressure at the surface. Cooler, denser air then rushes in to fill the void, creating a cycle of rising warm air and sinking cool air. This cycle sets up convection currents within the atmosphere.

Convection currents in the atmosphere are a major driving force behind the formation of winds. As warm air rises at the equator due to the Sun's heating, it creates a low-pressure area near the surface. Cooler air from higher latitudes flows in to replace the rising warm air, creating wind patterns. These wind patterns are known as the trade winds near the equator, prevailing westerlies in mid-latitudes, and polar easterlies near the poles.

Additionally, the rotation of the Earth (Coriolis effect) influences the direction of these winds, causing them to curve rather than blow in a straight line. This effect leads to the development of distinct wind belts and circulation patterns around the Earth.

Carnivores or meat eater, digestive system of them  is very short because meat is very easy to digest, hence the level of acid in the stomach is high while the digestive system of herbivores are long so their digestion is slow and the level of acid in the stomach is high.

A carnivore is an organism that eats meat, or the flesh of animals. Sometimes they are also called hunters while some prey are called prey. Carnivores are a major part of the food web.

A herbivore is an organism which feeds on plants, ranges from in small size tiny insects such as aphids to large, lumbering elephants to large animals like cow, buffalo . Herbivores are a major part of the food web.

Herbivores eat only plant or plant products like sheep, cow, goat, etc. Carnivores are those who can eat animals only, for example lions, tigers, etc.

8.multiple alleles

9.incomplete dominance

Explanation:

because i did it in savvas and i got it right.

The phenotype of an organism is influenced by the interactions of several genes. This implies that the organism's physical traits are governed by the interplay of several genes that it received from its parents.

When two alleles, or gene forms, are dominant, the dominant allele determines the phenotype of the progeny. This means that even if the other gene is recessive, the progeny will exhibit both traits if one of the alleles is dominant.

Sometimes a gene can take on several forms, producing more than two phenotypes. It is referred to as polygenic inheritance when more than one allele of a single gene affects the phenotype. Other times, two alleles are neither fully dominant nor fully recessive.

Answer:

because there is more potential food energy in the algae but not in the killer whales because nothing eats the killer whales

Because there is a greater potential for food energy in the algae than there is in the killer whales, who have no natural predators because nothing consumes them.

The biomass of an ecosystem is what determines its structure. The energy contained in living creatures is referred to as their biomass. Autotrophs are the producers in a food chain and are responsible for converting the energy from the sun into biomass. Each successive trophic level results in a loss of biomass. Lower trophic levels almost always contain a greater quantity of biomass than higher ones do.

In the vast majority of ecosystems, the producer level contains both the highest energy level and the greatest amount of biomass. Because of this, there is a greater potential for food energy in the algae than there is in the killer whales. This is also due to the fact that the killer whales do not have any natural predators.
