Answer:
The correct answer is : * Membrane carbohydrates function primarily in cell-cell recognition.
Explanation:
The carbohydrates (poly or oligosaccharides) associated with the plasma membrane, are covalently bound to it (to proteins or lipids). They are found in the outer part of the plasma membrane forming the glycocalix. Its main functions are:
-Cell recognition
-Support to the membrane.
Answer:
This single nucleotide change alters only one amino acid in the protein chain
Explanation:
The correct option is this: TWO DRAGONFLY SPECIES REGULARLY MATE BUT THEIR GAMETES ARE INCOMPATIBLE.
In biology, there are different types of reproductive barriers, one of these is prezygotic barrier. A prezygotic barrier is a kind of mechanism that prevent reproduction from occurring by blocking fertilization. In this case, the concerned species will be mating together, but their gametes will not be compatible and thus, zygote will not be formed.
A postzygotic barrier on the other hand is said to occur when the reproduction process is blocked after the formation of zygote or after fertilization has taken place. A good example of this is an hybrid mule that is sterile and can not reproduce.

Both have increased gradually over the past 150 years.
- Global warming is a gradual increase in the overall temperature of the earth's atmosphere generally attributed to the greenhouse effect.
- Global warming is the increase of the Earth's average surface temperature due to accumualtion of greenhouse gases in the atmosphere. Climate change is a broader term that refers to long-term changes in climate, including average temperature and precipitation.
- Effects of global warming are rising sea level Increased temperature, Habitat damage and species affected Changes in water supply
- Burning of fossil fuels, pollution from coal, natural gas, and oil are reason of global warming happening
