Answer:
1.capsule
2.membrane composed mostly of lipopolysaccharide
3.membrane composed mostly of phospholipids
4.peptidoglycan
Explanation:
The cell wall of gram-negative bacteria is located outside the cell membrane and is composed of a single layer of peptidoglycan, followed by a second membrane composed of phospholipids (often called outer membrane) and finally a lipopolysaccharide layer, these three elements constitute the gram-negative envelope. Also, some bacteria produce a viscous secretion that spreads in the surrounding environment, forming a slime layer known as a capsule.
Answer:
Still acidic water
Explanation:
A bog or bogland is a wetland that accumulates peat, a deposit of dead plant material—often mosses, and in a majority of cases, sphagnum moss. It is one of the four main types of wetlands. Other names for bogs include mire, mosses, quagmire, and muskeg; alkaline mires are called fens.
Answer:
B. The products of photosynthesis are the reactants of cellular respiration.
<span>Point mutations are of two types: Substitutions of bases that are the change of one base of DNA by another. And Transitions that are replaced on a pyrrhic basis by another pyrrhic or a pyrimidine by another pyrimidine. Transversions: substitution of a pyrrhic base by another pyrimidine or vice versa. These mutations are negative because they affect only one of the nucleotides, and therefore, only one triplet of bases are affected. When the mutation does not affect the individual it is a silent mutation. Chromosomal mutations Changes in the structure of the diploid chromosomes, where one of the chromosomes has a mutation, will have another normal. They can hinder the process of meiosis in the carrier since it hinders the correct pairing of the homologous chromosomes. It would produce an unfeasible offspring or with mutations.</span>
