The answer would be C. ABO blood types because the blood type AB is known as a codominant one
<h3><u>Answer;</u></h3>
Instantly transmitted
All of the information your brain receives is <em><u>instantly transmitted</u></em>.
<h3><u>Explanation;</u></h3>
- <em><u>Brain is the part of the central nervous system</u></em> together with the spinal cord.
- <em><u>Brain receives from sensory neurons, which carry stimulus, which are the changes in the environment, from the receptors for processing and interpretation.</u></em>
- <em><u>Brain inter-prates and process information it has received instantly and sends a response via the motor neurons, which carries the responses to the effector cells such as glands and muscles which trigger various actions.</u></em>

Explanation:
Answer:
All of these choices are correct.
Explanation:
Cell cycle is the process of growth and division of cell. It comprises of interphase and mitosis. In interphase the cell grows, replicates its genomic content and prepares itself for division. In mitosis the division occurs.
Cell cycle is controlled by a group of kinases called as Cyclin dependent Kinases (CDKs). They act by phosphorylating their substrates. They are of various types like Cdk1, Cdk2, Cdk4 etc. They become active when they bind to a regulatory protein called cyclin. They are also of various types like Cyclin A, Cyclin B, Cyclin C etc. Level of cyclin and corresponding CDK increases and decreases according to the stage of cell cycle. For example in S phase of cell cycle concentration of cyclin A and E shoots up. CDK2 is able to bind to these cyclin molecules and hence it becomes active.
Cell cycle has major checkpoints where the condition of cell is analysed before it proceeds to the next stage of cycle. If any abnormality is detected, repair mechanism is activated or the cell is killed. Checkpoints do not allow cell cycle to proceed in damaged cells.
p53 is a tumor suppressor protein which can halt cell cycle when it detects some abnormality in cell. It usually acts in G1/S checkpoint (before the DNA replication starts in cell) and G2/M checkpoint (before the cell division begins). Hence, all of the above statements are true.
