The morphological species concept is the concept which defines the species based on the morphological characters.
The species which can be grouped or organised on the basis of the morphological traits including the anatomy of the organisms arr called morphospecies and the concept is known as a morphological concept.

Thus, option-D is the correct answer.
Answer:
peroxisome
Explanation:
Adrenoleukodystrophy (ALD) is a X linked recessive disorder. In this disorder, fatty acid beta oxidation occurring in peroxisomes is impaired which leads to the accumulation of long chain fatty acid in cells.
The disease is caused by mutation in gene ABCD1 which codes for peroxisomal membrane transporter. This transporter transports the long chain fatty acids inside peroxisome for degradation hence problem with it interferes with the degradation process leading to build up of fatty acids inside cells.
The main damage is caused to the myelin sheath of the nerves which leads to hyperactivity and seizures. Other symptoms are speaking and listening problems, muscle stiffness, sexual dysfunction etc.
Answer:
In some experiments, several identical groups are set up, keeping conditions similar among them. In the <em>experimental </em>group, a change is deliberately introduced. In the <em>control </em>group, this change is not introduced. In this way, the researcher can determine if the change has an effect.
Explanation:
In every experiment that has to do with having a replicate, there must be a control group which is used to checkmate the effect of what is being tested, hence; nothing is introduced in the control group unlike the experimental group
As the hepatic portal circulation.
