We can tell from their structure that fatty acids are a good source of energy because of their large number of carbon-hydrogen and carbon-carbon bonds that they contain. Most fatty acids have straight chain compounds with an even number of carbon.
Answer:
Biodiversity hotspots are regions under surveillance of humans where threatened and endemic species of flora and fauna are grown. These regions have been identified as some of the world's most important ecosystems.
The two criteria for designation as a biodiversity hotspot are:
1. It must possess at least 1500 vascular plant species as endemics : It means the region must have a high percentage of plant species which are found no where else in the world.
2. It must have 30% or less native vegetation : It means that the plant species population is endangered and threatened to extinction.
A biotic factor is a living thing that has an impact on another population of living things or on the environment. Abiotic factors do the same thing, but they are non-living. Together, biotic and abiotic factors make up an ecosystem. To survive, biotic factors need abiotic factors.
A chromosome is a strand of DNA that is encoded with genes. In most cells, humans have 22 pairs of these chromosomes plus the two sex chromosomes (XX in females and XY in males) for a total of 46.
