Answer:
The main four types of reactions are direct combination, analysis reaction, single displacement, and double displacement.

One simple difference is that stems bear leaves, and roots don't. ... Similarity: Both stems and roots contain vascular tissues (xylem and phloem), the circulatory system of the plant. Difference: In herbaceous stems, the vascular tissues are contained in bundles; these bundles sit relatively near the surface of the stem.
The evidence of common ancestry is based on study of
three parameters; fossils record, homologies of various
organisms, and study of biogeography. Fossils record determines the similarity and differences of
bones as well as shells of different organisms over a given period of time. On the
other hand, studying of homologies involves assessment of mitochondrial DNA and
other proteins with an aim of finding similarity from one organism to
another. Finally, Biogeography is the
assessment of how continental drift might have separated organisms which had
got common ancestry and they were living together.
Here, we are required to list six of the properties of water and how they are essential for the existence of life.
These properties include:
- Water is a universal solvent
- Water is highly cohesive
- Water is a Substrate for microbial proliferation.
- Water supports cellular structure.
- Water has considerable buffering capability.
- Water is involved in Catabolic and Anabolic reactions.
- Water as a universal solvent is evident in its extensive capability to dissolve a variety of molecules and consequently transport them has earned it the designation of “universal solvent,” and it is this ability that makes water such an invaluable life-sustaining force. Biologically, water’s role as a solvent helps cells transport and use substances like oxygen or nutrients such as water-soluble vitamins.
- The cohesive property of water molecules helps plants take up water at their roots. Cohesion also contributes to water’s high boiling point, which is vital in animals body temperature regulation.
- Water serves as a substrate for Microbial proliferation because microorganisms grow best in high moisture environment.
- Water supports cellular structure: Water is quite important in biological structures. Water fills cells to help maintain shape and structure. The water inside many cells (including those that make up the human body) creates pressure that opposes external forces, similar to putting air in a balloon thereby creating a cushion.
- Water has considerable buffering capability: water buffers cells thereby protecting them from the dangerous effects of acids and bases. Highly acidic or basic substances, like bleach or hydrochloric acid, are corrosive to even the most durable biological materials.
- Water is involved in Catabolic and Anabolic reactions: Water is directly involved in biochemical reactions to build and break down important components of the cell. Photosynthesis, the process in plants that creates sugars for all life forms, requires water. Water also participates in building larger molecules in cells.

Answer:
B. The conditions in their muscles have become anaerobic.
Explanation:
In humans, cellular respiration occurs naturally in an aerobic condition (presence of oxygen) but anaerobic respiration can be adopted in specific or extreme cases. One of those cases is after or during a VIGOROUS EXERCISE.
What happens is that, after a vigorous exercise by an athlete, oxygen becomes insufficient in their muscle cells due to high consumption. Hence, their muscle cells switch to anaerobic respiration (lactic acid fermentation), which causes the build up of lactate in the muscle tissues. This lactate build up cause athletes to experience a painful and burning sensation in their muscles.
Hence, it all begins when "conditions in their muscles become anaerobic after an exercise".
