Hey, there!!
There is no place for virus, virions, prions in kungdom classification. The reason is they show both living and non living characters, which don't define them whether they are living beings or non living things.
As in 5 kingdoms, the only living organisms are classified.
- Kingdom Monera mostly deals with the organism which contains prokaryotic cells.
- Kingdom Protista deals with the organism which have eukaryotic cells.
- Kingdom Fungi deals with various fungal organism.
- Kingdom Plantae deals with various type of plants.
- Kingdom Animalia deals with various type of animals.
So, you can see that there is non of the kingdoms which deals with the organism which have similar characteristics like viruses, virions and prions.

Answer:
A = Activator
B = Effector
Explanation:
An activator is a protein which typically binds to a short (50–1500 bp) region of DNA which might be located either upstream (mainly) or downstream of a gene so as to cause increased transcription. This particular region of DNA is known as enhancer and activator is also known as transcription factor. Activator is a trans-acting factor which binds to the cis-acting factor which is enhancer so as to enhance transcriptional expression.
But another protein named as effector may restrict activator from binding to the enhancer leading to a decrease in transcriptional expression by binding to the activator allosterically. Allosteric binding of effector to the activator causes conformational change in activator so it can no longer bind the enhancer.
Answer:
Like a prokaryotic cell, a eukaryotic cell has a plasma membrane, cytoplasm, and ribosomes, but a eukaryotic cell is typically larger than a prokaryotic cell, has a true nucleus (meaning its DNA is surrounded by a membrane), and has other membrane-bound organelles that allow for compartmentalization of functions.
Explanation:
a. 25%
b.75%
c. 50%
d. Male cats have only one X chromosome in their DNA meaning that they should be unable to inherit different colours.
