Answer: Energy
Explanation:
If there is no chemical bonds in the substance or the bonds in the substances are so strong so there would be no energy released.
This is because there is a need of energy when any bond is formed and energy is released when bonds are broken down.
Energy is stored in the bonds which is released when bonds are broken down.
There would be no energy available for various processes and no movement of energy will take place.
Hey!
What let us know what are non-renewable resources:
Resources which can’t be renewed again after usage , it takes millions of year to form them again
These include fossil fuels
If we go on using fossil fuels it will be empty and we will run out of it.
A energy resource like fossil fuels is an non renewable! But why? Because rate of consumption is more than the rate of formation !
To sustain them , we must adapt to using of Renewable resources like Wind energy, hydro , wind etc .
I hope it’s clear!
Have a good day :)
Answer:
A. Chelicerates are a group of arthropods
E. Sea urchins are a group of echinoderms
B. Gastropods are a group of mollusks
Explanation:
Chelicerates are primitive arthropods having 6 pairs of appendages. 1 oral appendage used for feeding and lack actual mouth parts for chewing up "suck up predigested food". Cephalothorax is the largest and Abdomen contains gills.
Sea urchins are a group of echinoderms as they have spin skin , all marine and found in the bottom of the sea.
Gastropods are the largest and most varied group of molluscs. Gastropod means stomach footed, a typical gastropod is a coiled mass of organs enclosed in a dorsal shell, which rests on the foot having a head ans sensory structures on head and having an operculum.
Explanation:
As human population increases the rate of consumption of resources also increases. Economists postulates that available resources with which to satisfy our unlimited wants as a population is highly limited.
- Increase in population leads to an increasing pressure on available resources such as freshwater, land, air, energy e.t.c.
- Increasing population easily leads to deforestation. Deforestation is the loss of forest. Forest trees are used in construction of houses and industries. Forests also takes up space and they might have to be plundered to make way for new buildings. Eventually, the forest will be lost.
- Decrease in standard of living: increasing population will lead to a low standard of living. Resources meant to accommodate a certain number of people will no longer be sufficient for them.
- High poverty rate; if population continues to rise, the rate of poverty will increase too. There will be limited resources to cater for the well being of the populace as a whole.

Triglycerides vary with respect to the number of - C atoms and double bonds in the tails.
Triglycerides are esters derived from glycerol and three fatty acids. These are the main constituents of body fat in humans and other animals, as well as vegetable fat. There are two main types of triglycerides - saturated and unsaturated.
