The reason that some enzymes have a reversible effect is-
The ability of an inhibitor to attach to an enzyme non-covalently and easily dissociate from it is known as reversible inhibition. In a process known as competitive inhibition, the inhibitor, which mimics the substrate, attaches directly to the enzyme's active site and blocks the enzyme's function.
What are enzymes?Proteins called enzymes speed up chemical reactions and serve as biological catalysts. The molecules that enzymes can interact with are referred to as substrates, and the enzyme changes the substrates into new molecules known as products. In order to occur at rates quick enough to support life, almost all metabolic processes in the cell require enzyme catalysis.

Describe two ways that each of the following pairs are similar with each other and two ways in which they differ from each otherdesmosomes vs. tight junctions
Both desmosomes and tight junctions are clusters of proteins that act by binding membranes of adjacent cells. However, they have some differences. While desmosomes cross the plasma membrane and thus provide a stronger bond, the tight junction proteins (claudins) remain on the outside of the membrane and bind to the claudins of other cells; therefore, they provide a less strong binding than desmosomes, but function to make the tissue impermeable. The bladder is an organ that possesses many tight junctions.
In conclusion:
Similarities:
1- They bind cell membranes
2- They are composed of proteins
Differences:
1- Desmosomes go through the membrane, tight junctions do not.
2- Desmosomes are a stronger junction that holds the tissues together.
Tight junctions are less strong and their main function is to maintain an impermeable barrier.

Why is diffusion considered a form of passive transport?
Responses
A It has no effect on the health of the cell.
B It's carried out while the cell does other things.
C It's a process that occurs automatically.
D It requires no energy from the cell.
Answer:
D It requires no energy from the cell.
Explanation:
The diffusion considered as a form of passive transport because it requires no energy from the cell. Thus, option D is correct.
What is diffusion?Diffusion has been known as the process in which molecules of the solvent pass via a semipermeable membrane from a lower concentrations to higher concentration or from less concentrated solution to high concentrated solution. In the process of diffusion movement of water takes place.
There are mainly three types of osmosis and these are hypertonic, hypotonic, and isotonic. The process of osmosis has been passive transport as water moves from low solute concentration to the high solute concentration.

Different types of planets in the solar system illustrate density distribution throughout the period of planetary formation. Mercury, Venus, Earth and Mars are dense whereas Jupiter, Saturn, Uranus and Neptune are less dense.
The Solar System consists of the Sun with eight planets orbiting it. The four inner planets are those closest to the Sun .They are Mercury, Venus, Earth, and Mars. They are smaller and composed of metals and rocks and hence are dense. The four outer planets are Jupiter, Saturn, Uranus, and Neptune. They are larger and mostly made of gases, so the overall density is low A planet's density is related to its composition.
Mercury is the smallest in size. Earth and Venus are almost the same size, whereas Mars is about half their size.
According to the nebular hypothesis, Uranus and Neptune exist in a region where the density of the solar nebula is reduced and longer orbital times is longer . The two are thought to have formed in orbits near Jupiter and Saturn, where more material was available, and to have migrated outward to their current positions over hundreds of millions of years.

We have the data of the known areas
The new area is similar to Northeastern SA and Northen SA in terms of the type of prey and the growth rate, as well as rainfall.
And even if the density is greater, the total biomass is similar to Northeastern SA, so the population that the new area can support must be similar to the one in there.
Northeastern SA has an area of 1000 km2, so, according to the next graph, it can sustain at least 29 individuals. This means the new area should be able to support around that same quantity.

,• Viviparity,, where the younglings develop inside the body of the parent, are supported by them, and are born live. For example, humans.

c) an explosion would occur
d) to prevent the operator from becoming contaminated
e) the air would interfere with the electrons
Air has to be removed from the canister of the electron microscope because the air would interfere with the electrons (option E).
What is electron microscope?Electron microscope is any of the several forms of microscope that use a beam of electrons, rather than one of light, and thus has a much greater resolving power.
Electron microscopes are very powerful biological tools used to visualise variety of samples. They are used by scientists to view cells, tissues and small organisms in details. However, it should be noted that these living samples cannot be viewed on electron microscopes.
The vacuum inside the electron microscope is one reason why living samples cannot be viewed. The beam of electrons being aimed at the sample would be deflected when they hit air particles if the vacuum is not present.
Therefore, it can be said that the air is one component that must be eliminated to allow a direct passage of electrons.
