Life as we know it depends on the genetic code: a set of codons, each made up of three bases in a dna sequence and corresponding mrna sequence, that specifies which of the 20 amino acids will be added to the protein during translation.imagine that a prokaryote-like organism has been discovered in the polar ice on mars. interestingly, these martian organisms use the same dna → rna → protein system as life on earth, except thatthere are only 2 bases (a and t) in the martian dna, andthere are only 17 amino acids found in martian proteins.based on this information, what is the minimum size of a codon for these hypothetical martian life-forms?

Which of the following is NOT an extrasensory power?a. clairvoyance
b. hearing
c. precognition
d. telepathy

Answers

Among the options given above, 'hearing' is the one that is not an extrasensory power. Clairvoyance, Precognition and Telepathy are extrasensory powers. Therefore, the answer to this question is letter "B. hearing". I hope this helps.

Answer:

Option b=> hearing.

Option (b), can be done with our normal ears, hence, it is not an extrasensory power.

Option (c) and (d) that is precognition(knowing what is coming without seeing with norm human eyes) and telepathy(being able to read People's mind) respectively are both extrasensory powers.

What is converted to electricity at geothermal power plants?

Answers

The use of steamis essential in most power plants. Water is heated and dispatched through aturbine creating thermal energy. Later on, it is converted to electricity. Thesteam enables the turbines to rotate which activates a generator, producingelectricity.

The thermal energy (heat) is converted to electricity with a generator through a phenomenon called electromagnetic induction

The Calvin cycle includesA. The light-dependent reactions
B. An electron transport chain
C. The light-independent reactions
D. Photosynthesis

Answers

Answer:

C. The light-independent reactions

Explanation:

Photosynthesis consists of two phases: light dependent phase and light independent phase.

a) The light dependent phase of photosynthesis includes photolysis of water, release of oxygen and synthesis of ATP and NADPH.

b) Light independent phase of the photosynthesis includes chemical pathway to fix atmospheric carbon dioxide into glucose. Since this chemical pathway was first discovered by Calvin, it is called as Calvin cycle.
