Answer: Option D) Peptide bonds are amide linkages.
Explanation:
A peptide bond is formed between two amino acids with the loss of one molecule of water and the formation of an amide (CO-NH2) bond.
Usually the carboxyl group (COOH) of the first amino acid links with the amino group (NH2) with the loss of H2O, thus forming an amide linkage
The top of the stigma is sticky, and the pollen attatches to it, making it easier for bees to get it.
The answer is B.
Fermentation(an anaerobic process) is a way of harvesting chemical energy without using either oxygen or any electron transport chain.
Fermentation consists of glycolysis plus reaction that regenerate NAD+ by transferring electrons from NADH to pyruvate or derivatives of pyruvate.
There are many types of fermentation, lactic acid fermentation and alcohol fermentation are the most common two.
Answer:
The most likely explanation for the high rate of sympatric speciation that apparently existed among the cichlids of Lake Victoria in the past is sexual selection.
Explanation:
Divergent sexual and natural selection on the visual system has been confirmed earlier in sympatric, morphologically comparable sister species of Lake Victoria cichlids, but this seems not to reveal the exact morphological variations within them.
Cichlid fish reasonably describe the enormous inventory of standards of speciation and reproductive isolation without geographical or ecological separation.
Most of the recent observations have not confirmed the hypothesis, implying that sexual selection may be effective for the bursting cichlid speciation in the lake. Workroom practices have shown that reproductive isolation of three morphologically comparable species of rock-dwelling cichlid fish.
