Answer:
In meiosis I, the arrangement of any homologous chromosome along the center plane ( forgot the name for this) is independent of the arrangement of the other homologous chromosomes. There is thus equal probability for the chromosome to be in either of the two daughter cells after meiosis I. This is observed in meiosis 2 metaphase as well where the arrangement of each Sister chromatid about the ‘center plane’ is independent of each other. This independence observed during metaphase of meiosis I and meiosis II allows for chromatids to be in either gamete formed in equal probability, not affecting by other chromatids thus inheritance of one trait is not affected by the inheritance of another trait.
A b or d that’s the answer i think idek
Answer:
1.) Compounds that contain a fused ring systerm are called _steroids_. These have three 6-membered rings and one 5-membered ring. some of these compounds are found in biological membranes.
2.) _Fatty acids__ are the building blocks for many lipids, and they generally contain an even number of carbon atoms and an unbranched hydrocarbon chain
3.) _Glycolipid__ are formed when a carbohydrate is glycosidically linked to a hydroxyl group of a lipid. examples include gangliosides and cerebrosides. these are also found in biological membranes.
4.) _Triacylglycerols_are the storage form of lipids, accumulating in adipose tissue, and they can be used as metabloic fuel. these compounds have a polar part, made of three ester groups, and a nonpolar fatty acid tail.
5.) _Sphingolipids__ are made up of a long-chain amino alcohol joined, either by a glycosidic linkage or a phosphodiester linkage, to a fatty acid. these do not contain _glycerol__. they are abundant in the nervous system.
6.) When glycerol esterified to two fatty acids and a phophoric acid molecule a _glycerophospholipid_ is formed. These are found in biological membranes.
There would probably be fewer bacterial diseases that could attack humans because the appendages allow them to move or even in some cases protect them by having influence in their membrane creation and prevention of loss of water. The appendages allow bacteria to move and this certainly helps them in attacking humans or animals if they are of that type. Without the appendages they would probably also be easier to fight against with antibiotics.
