The base pairing rules in any DNA molecule are these:
• Adenine always pairs with Thymine(A-T)
• Cytosine always pairs with Guanine (C-G)
Answer:
The correct answer will be option-B
Explanation:
Stromatolites are the sedimentary deposited mounds made of layers of phototrophic microbes which were usually present in the primordial times. The stromatolites are one of the oldest fossils is known today which were formed in the shallow water.
They are composed of the phototrophic bacteria or cyanobacteria which survived and still survive by using the carbon dioxide and sunlight to make food material.
Since the bacteria are the prokaryotic organism therefore, the Option-B is the correct answer.
Answer:
Observation
Explanation:
The aspect of science that has to do with the recording of color, shape, and other physical features in order to identify a cell would be <u>observation.</u>
<em>Observation in science is the collection of data via perception or through the use of scientific instruments. Perception generally involves the use of human senses such as sight, touch, taste, and hearing to collect data in order to arrive at a conclusion. </em>
<u>The color, shape, and other physical features of a cell requires a perception of sight. Hence, it involves observation.</u>
The area affected by the ship that were involved in an accident is = 333 million liters
An oil spill can affect bird nesting near a contaminated body of water through its food chain.
<h3>What is oil spillage?</h3>
Oil spillage is defined as the release of used or oil wastes into a water body through a tanker, offshore drilling rig, or underwater pipeline.
The area affected by the ship that were involved in an accident can be calculated by the addition of the various areas affected by the tanker, ship and super tanker.
That is, 32,000 + 1,200,000 + 332,000,000
= 333,232,000
Which is approximately 333 million liters.
A bird that is nesting near the contaminated body of water can be affected through its food chain.
This is because birds which depends on fish can eat fish for this contaminated water which must have accumulated some level of harmful organic substances on its body surfaces.
Therefore when eaten by the bird their health would be affected negatively.

#SPJ1
Answer:
Water's high specific heat allows it to absorb a large amount of heat without changing much in temperature, keeping a relatively constant temperature in oceans and lakes which is beneficial to marine life. If water did not have a high specific heat, then it would increase in temperature very quickly and oceans and lakes would have drastic changes in temperature in very short periods of time. This could harm or kill the organisms living in them.
