Note: Question lack information. I have added full question with answer and explanation in info-graph.
Answer:
The cycle of human heart start with end of one beat to beginning of next beat is called cardiac cycle.
Answer:
Exocrine glands secrete sweat and oil while endocrine glands secrete hormones.
Explanation:
As she knows the endocrine and exocrine glands in respect of their origin from skin, so our answer must be related to the skin so that she can understand easily. So our answer should be as follows -
- Endocrine glands are those glands which secrete hormones directly to the blood stream but exocrine glands are those glands which secrete sweat and oils directly to the skin surface.
- A duct is often present in exocrine glands but endocrine glands lack ducts.
1. Waxy leaves-prevent evaporation of water
2. Some plants store water
3. Some plants have "reduced leaves" or thinner leaves to conserve water
Options are not provided in the question. The complete question is as following:
The role that p53 protein plays in suppressing inappropriate progression through the cell cycle depends on all of the following EXCEPT _______.
A) p53 indirectly blocks G1 to S transition in the cell cycle
B) p53 activates transcription of WAF1
C) p53 stability increases in the presence of unrepaired DNA lesions
D) the ability of p53 to bind DNA lesions
Answer: D) the ability of p53 to bind DNA lesions
Explanation:
The activities of the protein p53 are dependent on its binding DNA. Specific post-translational modifications to the p53 protein are important for efficient sequence-specific binding and transcription activities. Non-sequence-specific DNA binding can involve a broad range of p53 proteins and predominate as more serious DNA damage or greater induction of p53 protein. P53 Protein is not strictly essential for sensing and repairing DNA damage. Alternatively, p53 protein can control an apoptosis checkpoint by competing with DNA repair proteins for non-sequence-specific binding in the DNA duplex to exposed single-stranded regions.
Hence, while suppresing inappropriate progression through the cell cycle protein p53 does not bind to DNA lesions.
Hence, the correct option is D.
