We see the moon because the sun's light reflects off it. So the phases change depending on how much the sun reflects of it. The moon circles around the Earth so at certain times there will be a full moon and at certain times a new moon and everything in between.
Answer:
b: many genes code for RNAs that function directly in the cell
Explanation:
<em>The central dogma</em> theory describes the basic framework for gene expression in living organisms. Genetic information from DNA is encoded or transcribed as RNA which then becomes translated as proteins.
The processes that take place for gene to be successfully expressed are;
- Replication
- Transcription
- Translation
<em>Replication</em> is a process whereby DNA makes a copy of itself to be distributed in daughter cells during cell division.
<em>Transcription</em> is the process whereby genetic information in DNA is encoded as RNAs. The RNAs are short-lived as they are quickly utilized in protein synthesis or <em>translation </em>process.
Hence, the RNAs do not function directly in the cells but mere intermediaries in the synthesis of proteins.
<em>The correct option is b.</em>
Answer:
Eggs
Explanation:
Uric acid stones are one of the four types of kidney stones which are formed due to the high amount of uric acid in the human body.
When the concentration of the uric acid increases in the urine due to which urine becomes acidic, the uric acid gets stored in the urinary pathway in the form of stones.
To remove the uric acid kidney-stones, the food rich in purines must be avoided like meat, eggs and green vegetables like mustard, spinach, and whole grains are suggested.
Thus, the egg is the correct answer.
I think the answer is B, the interpretation of specific events as threatening or challenging. According to Hans Selye stress is a body's nonspecific response to any demand made on it, physical arousal to events seen as threatening, and mental arousal to events seen as challenging. However, there are effective strategies to cope with stress which include a sense of humor, relaxation, social skills, and social support.
