In making an experiment their are two types of variable that should be consider, one is the dependent variable and the other one is the independent variables. I the question that dependent variable would be the result or the effect of the gender of mice and the independent is the ways in determining it. So the variables should be fair if you want your result to have no bias. Thus the answer would be letter B. because it has the same variables but different in gender
<span>The presence of shared conserved insertion or deletions (indels) in protein sequences is a special type of signature sequence that shows considerable promise for phylogenetic inference. An alternative model of microbial evolution based on the use of indels of conserved proteins and the morphological features of prokaryotic organisms is proposed. In this model, extant archaebacteria and gram-positive bacteria, which have a simple, single-layered cell wall structure, are termed monoderm prokaryotes. They are believed to be descended from the most primitive organisms. Evidence from indels supports the view that the archaebacteria probably evolved from gram-positive bacteria, and I suggest that this evolution occurred in response to antibiotic selection pressures. Evidence is presented that diderm prokaryotes (i.e., gram-negative bacteria), which have a bilayered cell wall, are derived from monoderm prokaryotes. Signature sequences in different proteins provide a means to define a number of different taxa within prokaryotes (namely, low G+C and high G+C gram-positive, Deinococcus-Thermus, cyanobacteria, chlamydia-cytophaga related, and two different groups of Proteobacteria) and to indicate how they evolved from a common ancestor. Based on phylogenetic information from indels in different protein sequences, it is hypothesized that all eukaryotes, including amitochondriate and aplastidic organisms, received major gene contributions from both an archaebacterium and a gram-negative eubacterium. In this model, the ancestral eukaryotic cell is a chimera that resulted from a unique fusion event between the two separate groups of prokaryotes followed by integration of their genomes.</span>
I think its ADP because it breaks off the third phosphate.
Answer:
The functional group highlighted in pink alternates its position on the carbohydrate molecule
Explanation:
Complex carbohydrates or polysaccharides are large molecular weight molecules composed of repeating unit of simple carbohydrates which are joined together by covalent bonds known as glycosidic bonds. These glycosidic bonds are foremd between the carbon at position number 1 (known as the anomeric carbon) of one simple carbohydrate and a hydroxyl group of another simple carbohydrate.
The configuration of these linkages determines the properties and functions of the complex carbohydrates. The complex polysaccharides starch, glycogen and cellulose are all composed of glucose monomers linked together by glycosidic bonds.
In storage polysaccharides such as starch and glycogen whose function is to store the simple carbohydrate glucose for when needed by the organism, the glycosidic linkages are said to be in α-linkages, placing the functional groups (CH₂OH) all on the same side.
Even the branching points in glycogen are all in α-linkages. Humans have the enzymes to break these bonds so that starch and glycogen molecules can be metabolized by the body.
In a structural polysaccharide such as cellulose, the glycosidic linkages are β-linkages which results in alternating positions for the functional groups. Since humans do not have the enzymes responsible for the breakage of these linkages, hence, we cannot digest cellulose in our bodies.
