Answer:
Option (A).
Explanation:
Saddle joint is a type of synovial joint and also known as sellar joint. These joints are present in thumb, shoulder and inner ear.
The bone has one part concave inward and other part is convex outward. This bone can articulate with thumb's metacarpal and trapezium of the carpal bone. Saddle joints show abduction and adduction movements.
Thus, the correct answer is option (A).
Answer:C insertion of C at the start of the sequence
Explanation:
The oceanic crust is denser than the continental crust.
Also, the oceanic crust consists mostly of basalt.
What is the oceanic crust made of?
The topmost layer of the tectonic plates' oceanic part is called the oceanic crust. It is made up of two oceanic crusts: the upper crust, which contains pillow lavas, and the bottom crust, which is made up of troctolite, and ultramafic cumulates. The crust sits on top of the hard mantle's topmost layer.
Dark-colored rocks named basalt and gabbro make up the majority of the marine crust. It is lighter-colored rocks called andesite and granite that make up the continental crust, which is thinner and denser. Because of its low density, continental crust "floats" high above the viscous mantle, generating dry land. It develops as magma rises to fill the space between divergent tectonic plates and is consumed in subduction zones.

Answer:
K+
Explanation:
Leak channels are the gated channels that randomly open and close. The plasma membranes have many more potassium ion (K+) leak channels than the leak channels for other ions such as sodium ion. Also, the potassium ion leak channels are leakier than the sodium leak channels and allow exit of more and more K+ from the neurons. This makes the inside the neuron negative at rest and outside becomes more positive. In this way, the leakage of K+ across the K+ leak channels is mainly responsible for maintaining the resting potential.
Answer:
A. I only
Explanation:
Exotic animal species are really found in most countries and given that people these animals, they are very valuable. Species like lions, tigers, parrots, cheaters and even pythons are loved for exotic nature.
For this reason, they are caught, killed, shipped and sold in various countries or regions like dubia, Saudi Arabia etc. Its effects on the population of these species are disastrous.
If the inspection of goods coming into a country is intense and frequent, it will mitigate the shipping and sales of the species.
