Answer:
Saturated fatty acids have all of their carbon atoms bonded to hydrogen atoms.The lipids containing saturated fatty acid are solid at room temperature
Unsaturated fatty acids have some of their carbon atoms double bonded in place of hydrogen atoms.The lipids containing unsaturated fatty acids are liquid at room temprature.

Answer:
either one of the two alleles in a diploid individual.
Explanation:
A trait is expressed only when two alleles pair up. Thus, an allele pair during cell division assort independently into two individual alleles so that each gamete receive one of the two allele
For example
During gamete formation XX and XY allele pairs divide to contribute one allele to each gamete respectively.
Thus, XX allele pair will divide to give X gene to both the gamete
And XY pair will divide to give X gene to one gamete and Y gene to other gamete
Answer:
1) Use of aerosol sprays containing CFCS----Increase in greenhouse gases and causes Ozone depletion.
2) Use of extinguishers------ in the Combustion of fossil fuels.
3) Use of carbon tetrachloride as an
industrial solvent-----Agricultural activities
Explanation:
Aerosol sprays containing CFCS which is a harmful substance causes depletion of ozone layer which protects us from harmful radiation of the sun.
Carbon tetrachloride is used in agriculture activities such as a fumigant in the storage house for preventing the grains from pest attack.
Extinguishers are used for controlling the Combustion of fossil fuels.
<h3><u>Answer and explanation</u>;</h3>
- <u>According to the Law of conservation of mass; Mass cannot be created or destroyed in a chemical reaction.</u> The law of conservation of mass states that the total mass of substances taking part in a chemical reaction is conserved during the reaction. <u><em>For example in the equation;</em></u>
- <u><em>N2 + 8 H --> 2 NH3 + H2</em></u>
- <u><em>The number of hydrogen atoms and nitrogen atoms in the reactant side is equal to those on the product side.</em></u>
- Additionally; <em><u>the law of conservation of energy states that the total energy of an isolated system remains constant, that is it can not be created or destroyed, rather, it can only be transformed or transferred from one form to another.</u></em>
