Answer:
Option A.
Explanation:
True segmentation, where the body is divided into distinct, repeated segments or somites, is found in the following phyla:
A. Arthropoda, Annelida, Chordata.
B. enamel
C. pulp
D. cementum
The enamel, which is the hard, outer layer of our teeth, bears the force of chewing. It serves as a barrier against decay, and withstands the force and pressure exerted during the chewing process.
The part of the tooth that bears the force of chewing is the enamel. Enamel is the hard, outer surface layer of our teeth that serves as a protective barrier against decay. Though it is a very hard substance, enamel can be worn down with constant exposure to acids and certain foods. When we chew, our teeth work to breakdown food into smaller pieces, this action is borne primarily by the enamel. It is the enamel that withstands the force and pressure exerted during the chewing process and protects the interior parts of the tooth (dentin, pulp, cementum).

The enamel, which is the hardest and most highly mineralized part of the human body, handles the force of chewing. It protects the inner, softer areas of the tooth from damage due to chewing and biting. It's crucial to look after your enamel to prevent problems like cavities and other dental issues.
The part of the tooth that bears the force of chewing is the enamel. The enamel is the hardest and most highly mineralized substance in the human body. It forms the outermost layer of the tooth and is responsible for protecting the softer tissues inside the tooth from the impact of biting and chewing. The enamel's main function is to withstand the great forces exerted when we chew and grind food, and as such, it needs to be remarkably strong and durable.
In contrast, the crown refers to the visible part of the tooth, the pulp contains the tooth's nerves and blood vessels, and the cementum covers the root of the tooth and helps anchor the tooth to the jawbone.
It is essential to take care of your enamel by practising proper oral hygiene, such as brushing and flossing regularly, to prevent wear and tear, dental cavities, and other dental issues that can weaken the enamel.

B. stabilizes the position of the kidneys by holding them in their normal position
C. is necessary as a barrier between the adrenal glands and kidneys
D. produces vitamin D
raise
B. H2CO3
C. H2SO4
D. H3BO3
Answer: Option (C) is the correct answer.
Explanation:
An acid which is able to dissociate completely into ions in water is known as a strong acid.
For example,
Therefore, sulfuric acid is a strong acid as it dissociates completely into ions in water.
Whereas , , and are all weak acids as they dissociates slightly in water as follows.
Morover, sufuric acid upon dissociation is giving 2 hydrogen ions and rest all are giving one hydrogen ion.
Thus, we can conclude that out of the given options has the largest concentration of hydronium [H3O+].
