Receptors that are embedded on the cell membrane bind to chemicals outside of the cell and this binding process cause a chemical response on the inside of the cell.
These receptors that help in communication between the cell and the outside world are called cell surface receptors or sometimes transmembrane receptors.
A majority of chemical signals are water soluble thus unable to cross the fatty lipid bi-layer of the cell membrane. Their receptors, which are protein in nature therefore must span the membrane, detect their presence outside of the cell and transmit this information into the interior of the cell.
The correct answer is (c) They show which part of the brain are involved in specific activities.
The functional magnetic resonance imaging is used to measure the activity of brain by the detecting the change in the blood flow. This is done because the cerebral blood flow is associated with the neuronal activation. The functional area of brain has a higher blood flow that can be observed in functional MRI. The commercial application of functional magnetic resonance imaging is used in lie detectors. This technique is also used in research world and in some clinical trails. Physicians use this technique to see how risky a brain surgery can be. It is also used to learn how a normal, diseased, or injured brain functions.
Water has those melting and boiling points.
Answer:
C
Explanation:
They does not carry oxygen to injured areas of tissue
Answer:
The correct answer is BB genotype and BO genotype.
Explanation:
The human blood system or ABO system shows codominance due to the multiple alleles. That means three different alleles for human blood type are present are IA, IB, and i. For easy understanding can be stated as A (for IA), B (for IB), and O (for i).
If someone has blood type B could have a genotype of either BB or BO because of the dominance of B allele on O where is If A allele present with B allele it would show co-dominance.
Thus, the correct answer is the BB genotype and BO genotype.
