B
Explanation:
The reactants of photosynthesis are CO2 and H2O and the products are C6H12O2 and O2
the answer is not exact, but it is the closest to the actual equation
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.
1. Every framework has their doing in arranging our body capacities. Regardless of whether it's the heart drawing blood through our body and lungs boosting oxygen and discharge carbon dioxide. Endocrine gives the correspondence through hormones; secrete their hormones directly into the bloodstream and uses blood vessels as information channels. It stimulates sebaceous glands whereas the sex hormones affect the distribution of subcutaneous fat. In addition, the endocrine system regulates metabolism, growth and development of tissues, and sexual functions. The endocrine and integumentary systems correlate with the sense organs, which react to heat, cold, vibration, texture, and pressure. When such senses are produced by the sense organs they react to the senses and send the information to the endocrine system and therefore hormones are released which causes the mood swings according to the situation. For example, it reacts to the body with pleasure or discomfort related to the senses.
2. Atomic solution and radiology bring the procedures which analyze and regard maladies by utilizing radiopharmaceuticals as the pictures of body organs or envision certain infections. This involves radiations which are used to diagnose, treat and prevent certain diseases. In the present era, these procedures are the best and hence the most effective life-saving techniques. They are safe and painless as compared to other surgical treatments involving operations. They don’t even require anesthesia. Both of these techniques are used in diagnosing a disease and monitoring the course of an illness. They are then used for the treatment of any disease as well. Diseases such as cancer or heart disease are therefore treated by radiation technology.<span>
