A is mitosis because when a mitosis happen it always identical to the original cell it's like a clone.
And B is meiosis is different because when a mother have a child the child is not likely to look exact the same has the parent so they different.
Ans.
Gill slits or pharyngeal slits are defined as opening structures to throat, pharynx, or fish gills, by which passage of water from pharynx to exterior takes place in fishes. In primitive chordates, gill slits help in filtration of particles of food from surrounding water. In amphibians and fishes, gills are used for the gaseous exchange. In chordates that live in lands, such as mammals, gill slits found in developing embryos only.
Thus, the correct answer is 'option D). all chordates' as gill slits are present in all chordates at some stages of their development.
The main layers of Earths interior are the inner core, the outer core, the mantle and the crust.
<h3>What is the indirect evidence that helped us determine the layers?</h3>
Use of seismic waves is the indirect evidence that helped us determine the layers. When earthquakes occur they produce seismic waves.
The flow of matter occurs by convection. The dense crust subducts back into the mantle exert forces on crustal plates that then move, producing tectonic activity.
So we can conclude that The main layers of Earths interior are the inner core, the outer core, the mantle and the crust.

Answer: Exergonic reaction; Endergonic reaction
In coupled reactions, the energy released by an exergonic reaction is used to drive an endergonic reaction. ATP breakdown is often coupled to cellular reactions that require an input of energy.
Explanation:
Cellular reactions include Exergonic and endergonic reactions. An exergonic reaction is one that occurs spontaneously and brings about the release of energy (in form of ATP). On the other hand, an endergonic reaction proceeds only with the input of energy.
Thus, exergonic reactions are usually coupled to endergonic reactions
