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.

All parts of nonvascular plants must be near water because they have: B. tiny roots.
<h3>What is
photosynthesis?</h3>
Photosynthesis can be defined as a biological and chemical process through which living organisms such as green plants (autotrophs), transform light energy (sunlight) into stored chemical energy.
<h3>What is a
nonvascular plant?</h3>
A nonvascular plant can be defined as a species of low-growing, non-flowering plant that lacks specialized conducting channels, deep roots or vascular tissues (xylem and phloem) for the transportation of nutrients and absorption of water.
Generally, nonvascular plants usually possess tiny roots and the the dominant stage of their life cycle is the photosynthetic gametophyte. Some examples of a nonvascular plant include the following:
In conclusion, we can infer and logically deduce that all parts of nonvascular plants must be near water because they have tiny roots.
