Answer:
<em>The overuse of pesticides</em>
Explanation:
Pesticides are usually sprayed on plants so that the pest organisms can be killed. But these chemicals sprayed on plants can be toxic for humans when humans consume crops which have been sprayed with pesticides. Also, erosion causes these toxic chemicals to get eroded in the nearby lakes. The chemicals in the pesticides are harmful for every life that uses this water. Hence, the overuse of pesticides might kill pests but it is also toxic for consumption by humans.
It would be 100%. As you can see in my punnet square, there are no boxes with ww, which means that ll of the flies would have curled wings. (this is because you have to have two recessive genes for that gene to show)
So it would be
A. 100%
The natural selection process applies majorly inside back species wether than between species.
Answer:
D.all lipids contain fatty acids.
Explanation:
A.Lipids are fats, like oil, that are insoluble in water. ... The most abundant class of lipid molecule found in cell membranes is the phospholipid. The phospholipid molecule's polar head group contains a phosphate group. It also sports two nonpolar fatty acid chain groups as its tail.
B.The simplest definition is a lipid as any molecule that is insoluble in water and soluble in organic solvents. Most lipids are soluble to some extent in organic solvents such as hexane, ether, chloroform or benzene. They constitute a complex collection organic compounds that include fatty acids, (A,D, E and K).
C.There are two major types of lipids- simple lipids and complex lipids. Simple lipids are esters of fatty acids with various alcohols. For eg., fats and waxes.
D.Not all lipids have fatty acids. The operational definition of a lipid is a biomolecule is that is sufficiently hydrophobic to be more soluble in an organic solvent than in water. The common theme to their structures is a high percentage of hydrocarbon character.
E.Most lipid hormones are steroid hormones, which are usually ketones or alcohols and are insoluble in water. Steroid hormones (ending in '-ol' or '-one') include estradiol, testosterone, aldosterone, and cortisol. ... Amino acid-derived hormones and protein hormones are water-soluble and insoluble in lipids.
