Answer: Amino acids are absorbed via a Sodium cotransporter, in a similar mechanism to the monosaccharides.
Explanation: Amino acids are absorbed via a Sodium cotransporter, in a similar mechanism to the monosaccharides. They are then transported across the alabaster membrane via facilitated diffusion. Di and tripeptides are absorbed via separate H+ dependent cotransporters and once inside the cell are hydrolyzed to amino acids.
Yes, it is possible.
In this case both of the parental plants were heterozygotes and they manifested dominant allele in their phenotype, which is round seed.
P: Aa x Aa
F5: AA, Aa, aA, aa - possible genotypes in fifth generations.
A- dominant allele (round seeds); a- recessive allele (wrinkled seeds)
Wrinkled phenotype is manifested only if there are two recessive alleles present.
Speed and precision have been one of the main differences between an older and a more modern genetically modified food. In addition, these genetically modified organisms have yielded crop efficiencies although it also involves in various debates because of its unethical nature.
Answer:
The type of natural selection that occur when intermediate phenotype is favored is called STABILIZING SELECTION.
Explanation:
There are 3 major types of natural selection, these are: stabilizing, directional and diversifying selection.
A stabilizing selection is said to occur when natural selection favors average phenotype by selecting against extreme variations. Stabilizing selection usually leads to decrease in genetic variation of the population concerned.
A good example of stabilizing selection is that of snakes, which have deep green color that blend completely with their environment. This set of snakes will escape from predators more than others in the population, which have color that slightly differ from deep green and which do not blend very well with the environment. Those snakes, whose colour do not blend very well with their environment will get killed more easily by the predators and with time will become extinct while those with colour that blend with the enviroment will survive and produce more offspring.
The extinction of snakes from the population will lead to decrease in genetic variation.
This is because if the two metabolic processes were to be active at at the same time;
Two molecules of<u> ATPs</u> and <u>Guanosine triphophate </u>(sometimes used for energy transport) <u>will be expended per each cycle, with no compensatory rate of replacements present at the moment in the cell,this affects cell metabolism for energy availability</u>
<u>2</u> Both<u> Glycolysis and Gluconeogensis </u>are both<u> exergonic processes in cells. </u> The heat energy liberated from these Calorinogenic effects will be higher than what the natural thermodynamic barrier of cells can withstand. Consequently; the heat will raise temperature of the cells affecting metabolic activities of hormones and enzymes which are (proteins) ,and easily denature by high temperatures.
However, in muscles cells,gluconeogeneis is a compensasory process of Glycolysis. This because during active exercise with high metabolic demand in muscles cells, glucose is rapidly metabolise to to pyruvate,(but not at the rate that the Citric acid cycle can metabolise) for Lactic acid production by muscles cells for energy production. Pyruvate must be broken down rapidly so that NAD+ will be available for Glycolysis to continue. Therefore to sustain Glycolysis at this rate continuous supply of glucose is supplied from Gluconeogenesis.
