Answer: The question is incomplete,below is the complete question.
What are the terms describes the dna–protein complexes that look like beads on a string?
A) Chromatin
B) 30-nanometer fibre
C) Histones
D) Nucleosome
The correct answer is option D
Explanation: A Nucleosome is the basic fundamental unit of a DNA, and the fundamental sub-unit of a Chromatin.
The Nucleosome is the basic packing unit of DNA,it is built from histone proteins. A nucleosome is made up of 8 histones proteins resembling a thread wrapped round a spool.
The smallest bundle of DNA is known as a Nucleosome,a Nucleosome is produced through interaction between DNA and histone proteins.

The correct answer is 'If molecules are small enough, then they can pass through the semipermeable membrane because they can cross the semipermeable membrane from their small pores or openings'.
The semipermeable membrane is permeable to few molecules, and the smaller molecules pass through the molecules from small pores present in the semipermeable membrane. The size of the big molecules are large, so, they cannot cross through semipermeable membrane.
It causes eutrophication which means that the algae have too much nutrients and take over the pond, use the oxygen so there is not enough left for marine life, which die as a result.
Answer:
The correct answer will be option-Thalamus
Explanation:
The somatosensory pathway is the pathway which sends the receptor generated sensory impulses mostly the temperature and touch to the central nervous system.
The pathway is composed of three types of neurons called primary order neuron, second-order neuron and tertiary order neuron.
The second-order neuron receives the signals from the first-order neurons and carries the signals to the relay part of the brain called thalamus. The thalamus is present in the forebrain region of the brain where it receives, analyses and sends the signals to the different region of the cerebral cortex.
Thus, the thalamus is the correct answer.
