Which statement is true about oxygen and nutrient levels of rivers? TIMED TEST

Your answer:

Fast moving mountain streams which flow over rocks and waterfalls are high in oxygen due to the amount of surface area of the water that is exposed to the air.


Fast moving mountain streams are high in nutrients. Organisms have adaptations to hold on in fast moving water, resulting in a large diversity organism.


Slow moving flood plain rivers are high in oxygen due to the amount of surface area of the water that is exposed to the air.


Slow moving flood plain rivers are low in nutrients. These rivers move too slow for plant growth and other organisms to survive.

What is electronegativity?

The term "electronegativity" describes how attracted an atom is to the bonding electrons in molecules as opposed to other atoms.

American chemist Linus Pauling developed a set of dimensionless variables known as electronegativity values that vary from a little under one for alkali metals to a maximum of four for fluorine.

Electropositive elements are those that are on the left of the periodic table and have low electronegativities. We shall use the key attribute of the order of electronegativities F > O > N > C to explain the chemical properties of organic molecules.

Therefore, Zinc 1.65, Chromium 1.66, Tungsten 2.36 and Iodine 2.66.

List the six nitrogen bases that would pair with the following sequence of bases in a strand of DNA : T C G A C A

Answers

Answer: thymine (T) Cyostine (C) guanine (G) adenine (A)

Explanation:

Guanine (G) is complementary to cytosine (C), and adenine (A) is complementary to thymine (T). Hence, the nitrogenous bases that would form for the DNA bases TCGACA are AGCTGT.

     

How does base pairing take place in DNA?

A DNA double helix is joined together by the hydrogen bonds that are formed between the nitrogenous bases in the opposite strands. Adenine (A), Guanine (G), Cytosine (C), and Thymine (T) are the nitrogenous bases present in the DNA. Both adenine and guanine are purines. They make bonds with pyrimidine.

Adenine (A) of one DNA strand makes a double bond with Thymine (T) of the opposite DNA strand. The guanine (G) of one DNA strand makes three hydrogen bonds with the cytosine (C ) of the opposite DNA strand. As there are three hydrogen bonds present in guanine and cytosine (GC), they require more energy to break the bond. Adenine and thymine (AT) have two hydrogen bonds, hence they require less energy than GC bonds.

Hence, in a DNA strand, the complementary strand of TCGACA is AGCTGT.

The correct answers for these questions are option D, A, A, A, D.

ATP molecule and photovoltaic cells are similar to each other because both ATP and photovoltaic cells use energy of the sun that is used to separate electrons from atoms.ADP molecule is a high-energy output of photosynthesis that is used for different activities in the cell.In photosynthesis, light energy is captured as usable energy which is further used in the production of glucose molecules. The simplified equation for photosynthesis is carbon dioxide + water + light → sugar + oxygen. The sugar is stored in the body parts whereas oxygen is released in the atmosphere through stomata.Starch is a carbohydrate formed by bonded glucose molecules represents dehydration synthesis. Dehydration synthesis is the formation of larger molecules from smaller molecules with the release of water molecule.

Flooding helps spread organic material, nutrients, and sediments which enrich floodplain soils. They also replenish water resources and trigger life processes such as bird breeding events, migration, and seed dispersal in flora and fauna adapted to these cycles, while good soil moisture can allow crops and pastures to be established.

The option which is an example of an automatic regulatory reaction is: A. sweating

Automatic regulation can be defined as a biological process that occurs within many living organism due to the function of an internal adaptive mechanism that typically works to mitigate (lessen or adjust) its system's response to stimulus.

Generally, the body organs and system that are considered to carry out some degree of automatic regulation are:

The brain.The heart.The kidney.

Hence, an automatic regulatory reaction is a biological process that happens in response to other bodily process and stimuli.

For instance, the nervous system produces an automatic regulatory reaction to emotions (fear), illness and heat such as sweating.

Sweating is an automatic regulatory reaction of the human body to protect and mitigate the effects of an extreme change in temperature (heat).
