O Biology is the science of exception, Justify it with
examples
Answer:
Biology deals with living organisms which show enormous variations and, therefore, numerous exceptions are found.
There are two reasons:
Each organism evolved in a different way to adapt to their environments the best way possible.
It is not really so. There are common rules to biology as in physics, but the problem is we study much more complex systems. More complexity results in more emergent properties, thus they appear to be exceptions.
Biology deals with living organisms which show enormous variations and, therefore, numerous exceptions are found.
justifying it with examples:
1. All living cells have a nucleus except mature red blood cells of mammals.
2. Red blood cells of all mammals are without nucleus except those of camel.
3. Stem is the part of plant above the ground but potato, corm and ginger are underground stems.
4. Blood of all vertebrates is red due to the presence of hemoglobin but a shark, Carcharhinus, has colorless blood.
by the above examples you can see that biology the science of exception.

Liquids have not fixed shape and they readily flow.
Gases are random and they occupy the contains they fill .
Volume is the amount of space occupied by a substance. Gases can take up any amount of space in a container. Liquids can readily flow and take up spaces too. Solids are fixed and have a definite volume.Some scientists predict that if global warming continues over the next few centuries, melting of the polar caps will raise the level of the oceans, causing some peninsulas to become islands. How might this change eventually affect the species that live on these peninsulas

Stand and let your hands hang next to your sides for a few minutes. Then, look at the backs of your hands. Do you see any bumps on the surface on top of your veins? What might those be, and what are their function?
When you stand and let your hands hang next to your sides for a few minutes, the bumps you see on your veins are the valves that help move blood to the larger veins.
What we know about vein valves.There are valves located throughout the veins in our bodies. Most of these are located in points where smaller venules fuse with the larger veins.
Their function is to prevent blood from flowing back into the smaller veins, thus helping with the normal blood flow of the body.
Given that the veins in our bodies are littered with small valves to help the blood return to the heart correctly, we can confirm that these are the small bumps that we can see when letting our hands down for a few mins, as they fill with the blood they try not to let flow back into the smaller veins.

Running for a long period of time, such as during a marathon, can result in muscle fatigue. Which process is important to a runner at the end of a marathon?
A. lactic acid fermentation to produce ATP without oxygen
B. Alchoholic fermentation to release carbon dioxide
C. The Krebs cycle to produce NADH and FADH2
D. The electron transport chain to produce ATP
The process that is important to a runner at the end of a marathon is lactic acid fermentation to produce ATP without oxygen (Option A).
Cellular respiration refers to the reactions by which aerobic cells normally produce energy in the form of ATP by using energy stored in the chemical bonds of foods and oxygen.Muscle cells can produce ATP by both cellular respiration (aerobic conditions) and acid lactic fermentation (anaerobic conditions).Acid lactic fermentation is energetically much less efficient than cellular respiration, but ATP production in cellular respiration is much slower than in fermentation, thereby muscle cells use this pathway (fermentation) when they cannot get oxygen fast enough to meet their energy requirement.In conclusion, the process that is important to a runner at the end of a marathon is lactic acid fermentation to produce ATP without oxygen (Option A).

Which of the following shows a correct base pairing in DNA?
A and G
T and G
C and A
Gand C
Answer: G and C
Explanation: DNA carries the hereditary information for organisms. W ithout DNA, our species would be unable to pass traits from generation to generation. DNA controls all aspects of an organism. It tells spiders how to spin webs, birds to lay eggs, and what color to make your eyes. The genetic information in DNA is stored as special chemical sequences, called chemical bases. The chemicals bases are adenine (A), guanine (G), cytosine (C), and thymine (T). Each base connects with another to form base pairs. Adenine always pairs up with thymine. Cytosine always pairs up with guanine
