6 0

Answer:

The third answer

Explanation:

They ran at the same speed because if you divide 7.2 by 2 it equals 3.6!

And 3.6 x 2 = 7.2   They may have traveled for different periods of time but if they had traveled at the same time and ended at the same time their speed would be the same.

How does paving and concreting areas affect watersheds?
dezoksy [38]

Answer:

As the amount of impervious paved surfaces increase, watersheds become more vulnerable to pollutants. When rains fall on a conventionally paved impervious surface, the precipitation is generally directed down storm drains, which can result in flooding and overwhelming the storm water management system.

Miller's classic experiment demonstrated that a discharge of sparks through a mixture of gases could result in the formation of
beks73 [17]

Answer:

The correct answer will be-gas absent in primordial atmosphere (oxygen).

Explanation:

The Miller experiment was performed in 1953 to show that organic molecules can be formed from the inorganic molecules in the conditions resembling the primordial atmosphere.

Same conditions were created to the unstable atmosphere like a mixture of gases which included- methane, sulfur dioxide and hydrogen but lacked oxygen as it was absent in the primordial atmosphere.

Thus, gas absent in the primordial atmosphere (oxygen) is the correct answer.

When the cardiac muscle cell is at rest, the concentration of _____________ is greater on the outside of the cell?
nordsb [41]

When the cardiac muscle cell is at rest, the concentration of sodium and calcium is greater on the outside of the cell.

The resting membrane potential (the cardiac muscle cell is at rest) is characterized by more negatively charged inside of the membrane comparing to the outside. The main ions found outside the cell at rest are: sodium (Na+), and chloride (Cl−), and Ca2+ whereas inside the cell it is mainly potassium (K+).

Using a microscope, Quinlin notices a small green organelle inside a cell. Which of the following is most likely to occur first
jek_recluse [69]

Answer:

D.The light-dependent reactions absorb sunlight and transfer the energy to electrons.

Explanation:

Firstly, the organelle that was described as small green organelle inside a cell as noticed by Quinlin is the CHLOROPLAST. Chloroplast is an organelle present in the cells of green plants, in fact, it makes plants green. Chloroplast is the organelle where the unique process of PHOTOSYNTHESIS occurs in plant cells.

However, the photosynthetic process is divided into stages namely: light-dependent and light-independent stages. The light dependent stage, which involves the production of ATP (energy carrier) and NADPH (electron carrier), must PRECEDE the light independent stage or Calvin cycle. Chloroplast contains a pigment called CHLOROPHYLL, which absorbs light energy from the SUN in order to power the light dependent stage of photosynthesis.

Hence, the light-dependent reactions, which absorb sunlight and transfer the energy to electrons must occur first in the organelle.
