1. Camouflage
2. Competition
3. Competition
4. Symbiosis
<h3><u>Explanation</u>:</h3>
The camouflage is defined as the property of the living organisms that make them to prepare their body to perfectly match with their surroundings so that they cannot be recognised by their hunters. This makes them survive more in an environment with full of competition.
The competition is an interaction between the organisms where in a particular environment, different organisms compete for a particular prey for their living. Here the theory of the survival of the fittest work.
The symbiosis is an interaction between two or more species which leads to benifit of both the species in their living. Here one species help other in a form and other species do the same. There's benifit for both in the interaction.
Option A, B, D are only applicable for steroid hormones ( hydrophobic)
So the answer is C
Answer: Thalamus
Explanation:
The thalamus part of the brain is known as the relay station for all the sensory information. This information can be any sought of smell, light, taste et cetera.
It is relayed further via thalamus. Myelinated fiber bundle originates from the lateral surface of thalamus and it terminates at the cerebral cortex.
It is a relay station for the information from brainstem, spinal cord and cerebrum towards the cortex.
Answer:
The correct answer will be option-A.
Explanation:
The females carry two X-chromosomes in their cells but one of these X-chromosome gets permanently inactivated during embryonic development.
The X-inactivation is known as lyonization which ensures that only one functional X-chromosome should be present like in males. This process is a random process and therefore a female can have both the functional X-chromosomes and males can also have a functional X-chromosome.
Thus, option-A is the correct answer.
