Answer:
It is expected to obtain 576 individuals with normal wings and body with normal hair, 192 with normal wings and hairy body, 192 with vestigial wings and body with normal hair, and 64 with vestigial wings and hairy body.
Explanation:
Since only the wild-type of the offspring cross each other and since the parents have antagonistic phenotypic characters for each gene, all the progeny produced in the F1 is heterozygous with VgvgHh genotype, where
Vg: Normal wings.
eg: Vestigial wings.
H: Body with normal hair.
h: Hairy body.
Once F1 reproduces with each other, the Mendelian proportions 9/16, 3/16, 3/16, 1/16 expected in the F2 generation are produced.
Since in total there were 1024 individuals in the offspring, this amount is multiplied by the expected proportions, giving rise to the mentioned result.
The correct answer is: The vasomotor center would increase sympathetic output to arterial smooth muscle to increase TPR.
Baroreceptors are mechanoreceptors (sensors or modified nerve endings) found in the blood vessels and their function is to detect the change in blood pressure and participate in the regulation of it (so that proper blood pressure can be maintained). The action of baroreceptors or baroreflex works as a negative feedback loop: when the blood pressure is decreased, baroreflex activation also decreases (baroreceptors are active even at normal blood pressures) and causes heart rate to increase.
Decreased blood pressure leads to lower baroreceptor “firing” which then results in an increase in sympathetic stimulation of the heart and sympathetic stimulation of the peripheral vessels, resulting in vasoconstriction. As a result blood pressure increase.
The reason why the infant of the mother has this type of abnormality is because of a history that she could have done that could have contributed to this abnormality, what would likely be the cause and the reason it occurred is because the mother has a history of chronic alcohol abuse.<span />
Answer:
Hydrogen and electrons
Explanation:
Nicotinamide adenine dinucleotide (NAD) and flavin adenine dinucleotide (FAD) serve as reducing power during energy transfers. One NAD+ accepts one hydrogen ions and two electrons and becomes reduced into NADH. Likewise, FAD accepts two hydrogen ions and two electrons and is reduced into FADH2. Oxidation of NADH and FADH2 into NAD+ and FAD respectively releases both hydrogen ions and electrons.
For example, some of the energy of glucose released during glycolysis and Kreb's cycle is temporarily stored in the form of NADH and FADH2. Oxidation of NADH and FADH2 via electron transfer chain of mitochondria releases both electrons and hydrogen ions (protons). The protons are pumped across the inner mitochondrial membrane to generate the proton concentration gradient.
