Answer:

Temporomandibular joint

Explanation:

The lateral excursion refers to the side to side gliding movement of jaws that is unique to mammals. Lateral jaw movement is allowed by a temporomandibular joint which is a joint formed by the condylar process of the mandible and the mandibular fossa and articular tubercle of the temporal bone. This joint has features of both hinge and plane joints.

At the temporomandibular joint, the mandible is movable since the temporal bone is anchored by sutures to the other bones of the skull. During grinding of food, when the posterior teeth are pulled into occlusion, mandible exhibits side to side movement. This lateral jaw movement is observed in animals such as cows and horses during chewing of their food.

In an enzyme immunoassay, the enzyme

antoniya [11.8K]

Answer:

is bound to the constant region of the secondary antibody.

Explanation:

Enzyme immunoassays are the techniques used to detect the presence of antigens with the help of antibodies. Each of the antibody molecules has a constant and variable region.

The primary antibodies are added to the wells. The constant region of the secondary antibody is bound to an enzyme while its variable region is free so that it can bind to the specific antigen.

Addition of substrate to the system is followed by visualization and/or evaluation of antigen as the reaction between enzyme and substrate produce some visible changes such as color change.

The MOST distinctive feature of ape dentition, which clearly distinguishes apes from Old World monkeys, is

Ugo [173]

The most distinctive feature of ape dentition, which clearly distinguishes apes from Old World monkeys, is a Y-5 molar pattern.

<h3>What is the Y-5 molar pattern?</h3>

This is a distinctive type of molar teeth pattern found in apes and hominoids.
In this, 5 cusps or raised surfaces are present on the grinding surface of teeth, roughly forming a Y- shape. Therefore, this is also known as Y-5 pattern.
Whereas Old world monkeys have only 4 cusps on their lower molars present in a bilophodont pattern.
A Y-5 molar is formed when the tooth is divided into different pieces which form the complete structure of the tooth.
In bilophodont pattern the tooth is divided into 2 symmetric sections.
The dental formula of apes is 2.1.2.3/2.1.2.3 i.e. 2 incisors, 1 canine, 2 premolars, 3 molars.

muminat

Answer:

Option (2).

Explanation:

Zygote is formed by the fusion of the male and female gamete during the process of sexual reproduction. The zygote undergoes further development inside the female womb.

The embryonic period starts from the third week after the conception. The important organs and structure development occur during the embryonic period. The formation of three germ layers occur in this period.

Thus, the correct answer is option (2)
