The correct answer is b. Head movement → Inner ear receptors → Vestibular nerve → Cerebellum.
The balance and equilibrium of the body is maintained by inner ear in the human beings. The parts of internal ear which takes part in balancing and equilibrium are the semi-circular canals and the vestibule. On the movement of head, the otoliths are pull in the direction of gravity.
Answer:
No
Explanation:
The interaction between two individuals in which both individuals gets benefited from each other is known as mutualism. So in mutualism both individual helps each other for their survival. For example in lichens, fungi provide nutrients to algae and algae provide food to the fungal partner.
Here beetles are benefitted because they are getting food by chewing the petals and harvesting nectar but the trees which produce these flowers are not getting benefits as beetles are not dusted with pollens so their genes are not getting spread by beetles to other flowers. Therefore this interaction is not a mutualistic interaction.
This would be an isotonic solution. If a cell is placed in a solution of salt with the same concentration of salt in the cell, nothing will happen. The water level will stay the same.
Answer:
animal cell has no cell wall, plant cell has chloroplast and bacteria has no nucleus
Explanation:
This question is long and it is late here, but I can help you understand it. DNA consists of 4 nucleotide bases: Adenine (A), Thymine (T), Cytosine (C), and Guanine (G). When DNA is transferred to RNA, you use the complimentary nucleotide base to each as follows:
Adenine changes to Uracil (replaces Guanine in RNA)
Thymine changes to Adenine
Cytosine to Guanine and vice versa
So, the DNA code ‘TAC’ will have the mRNA complimentary strand of ‘AUG’. When changing mRNA to tRNA, you do as follows:
Change A to U
U to A
C to G
G to C
It’s that simple. Then, to change to amino acids, you need to use the codon chart attached (a codon is 3 nucleotide base pairs)
For example, mRNA codon AUG codes for the amino acid Methionine. Hope this helps.
