What happens to oxygen levels when animals are introduced? Why?

Answer:

During inhalation, the diaphragm contracts and pulls downwards, the ribcage expands, allowing oxygen to be sucked in through negative pressure, which causes the lungs to inflate.

During exhalation, the diaphragm and ribcage relax, returning to their normal positions, allowing the oxygen out of the body, thus deflating the lungs.

Fish will eat tadpoles if they can get to them. The only way to stop them would be to give the tadpoles a space that the fish can't get to, like a shallow area with a barrier (plastic mesh would work but make sure the fish can't get caught in it) or lots of plants, or make a separate wildlife pond.

If tadpoles are in an area where there is a lot of plants in the water it would be much harder for fish to get to them.

According to the research, an enzyme is a protein that simply helps speed up the catalytic process of biochemical reactions.

It is a macromolecular substance that catalyzes one or more biochemical reactions in a more or less specific way, at relatively low temperatures.

In this sense, it can be natural or synthetic, composed mainly of protein, they have specificity because they have a series of their own identity signs that determine them in each and every one of their aspects.

Therefore, we can conclude that according to the research, a reaction under the control of an enzyme with a catalytic effect reaches equilibrium much faster.

The total lifespan of a star is directly related to its initial mass, as the star's mass determines its internal temperature, pressure, and fusion reactions, which are the main factors of its energy.

The more massive a star is, the faster it burns through its fuel and the shorter its lifespan because massive stars have more fuel to burn and generate more heat, while low-mass stars have less fuel to burn and generate less heat and pressure in their cores, causing them to fuse elements at a slower rate.

Hence, the total lifespan of a star is directly related to its initial mass.

The lagging strand contains Okazaki fragments

Explanation:

During DNA replication, the two strands of DNA are separated and replicated via distinct mechanisms.

The leading strand is synthesised continuously by DNA polymerase in the 5'-3' direction.

However, DNA polymerase can only work in one direction (5'-3') so the other strand cannot be synthesised continuously in the reverse direction.

The other strand, the lagging strand, has to be synthesised discontinuously in the 5'-3' direction. This forms fragments- called Okazaki fragments - that are later joined up.
