Biology

zubka84 [21]3 years ago
3 0

Answer:

The correct answer will be option-D.

Explanation:

Photosynthesis proceeds in two stages: light-dependent and light-independent reaction.

The light-dependent begins when the chlorophyll pigment of the photosystem absorbs light energy.  This absorption causes the excitation of the electrons provided by the chlorophyll molecule.  

The excited electrons accepted by electron acceptor molecule from reaction center and a chain of electron flow begin called electron transport chain.

This transport of electrons creates a scarcity of electron in photosystem which causes splitting of the water molecule as a result of which oxygen gas is released.  

Thus, option-D is the correct answer.

The dna content for an organism is analyzed. The results showed that 21% of the nucleotides contained the nitrogenous base adeni
Serjik [45]

If the results show that 21% of the nucleotides contain adenine, then the cytosine fraction in vivo is 29% and the thymine fraction is also 21% (options A and C).

<h3>Define double helix model of DNA?</h3>
  1. DNA is a double helix molecule made up of two long strands of nucleotides.
  2. There are four types of nucleotides in DNA, each containing a different nitrogenous base: adenine, guanine, thymine, cytosine.
  3. Adenine always pairs with thymine and guanine pairs with cytosine, according to the base-pairing rules.
  4. As a result, the percentage of adenine equals the percentage of thymine, and the remaining percentage equals guanine + cytosine (29 + 29 = 58 >> 58 + 21 + 21 = 100).
  5. Therefore, if the results show that 21% of the nucleotides contain adenine, then the percentage of cytosine in vivo is 29% and the percentage of thymine is also 21%

The complete question is as follows:

The DNA content for an organism is analyzed. The results showed that 21% of the nucleotides contained the nitrogenous base adenine. What else can be inferred based on this data? Select all that apply

A) The percentage of cytosine is 29%.

B) The percentage of adenine is 21% for all organisms.

C) The percentage of thymine in the organism is also 21%.

D) The percentage of guanine in the organism is also 21%.

E) The percentage for cytosine in the organism is also 21%.

What happens to the heat and moisture from the ocean?
LUCKY_DIMON [66]

Answer:

The answer is A

Explanation:

When water molecules are heated, they exchange freely with the air in a process called evaporation. Ocean water is constantly evaporating, increasing the temperature and humidity of the surrounding air to form rain and storms that are then carried by trade winds.
