Answer: The monosaccharides that are correctly paired with their class are (A) fructose : hexose ketose, (C) glyceraldehyde : triose aldose and (F) dihydroxyacetone : triose ketose.
Explanation: Monosaccharides are classified into two: aldose and ketose. In open chain form, monosaccharides have unbranched chains in which all the carbon atoms are linked by single bonds, one of the carbon atoms is double bonded to an oxygen atom to form a carbonyl group and each carbon atom has a hydroxyl group. An aldose is a monosaccharide in which the carbonyl group is at the end of the carbon chain while a ketose is a monosaccharide in which the carbonyl group is at any other position. A triose is a sugar with three carbon atoms, sugars with four, five, six and seven carbon atoms are known as tetrose, pentose, hexose and heptose respectively.
Fructose is a hexose ketose, erythrulose is a tetrose ketose, glyceraldehyde is a triose aldose, erythrose is a tetrose aldose, ribose is a pentose aldose while dihydroxyacetone is a triose ketose.
Answer:
That is false because some people are blind, or deaf,
Explanation:
The cell membrane is one phospholipid bilayer, and the nuclear membrane is two phospholipid bilayers. Cell and nuclear membranes are different.The cell film encases the whole cell while the atomic layer encases the core. ... WHEREAS, Cell membrane covers the whole outer with abi-layer of the cell.
Answer:
Centromeric DNA
Explanation:
Genes are responsible for formation of proteins. A codon produces a single amino acid and it comprises of three base pairs. The whole DNA of organism does not contribute to encode protein. There are sequences in DNA that does not contribute in coding known as non-coding DNA and perform different functions. These may include the O O O 5-end, DNA coding for a signal sequence, noncoding intron and O promoter sequence .
The centromere is the part of DNA that links the sister chromatids. The centromere is not converted to mRNA or proteins. It is also not involved in regulation of genes. So it did not contribute to 864 bp found in the yfg gene.
Interspecific competition can occur between two different species competing for the same resource in an ecosystem. So for this particular bug population, there may be another insect species that competes for the same food source or another resource, such as material or space for breeding habitat. This can lead to selective pressure, and may result in the different species evolving a more specific diet or inhabiting a niche environment.
