Answer:
In the given case, it is clear that the sympathetic part of the autonomic nervous system is on in Mr. T. It can be suggested due to the increase in heart rate and appearance of cold and pale skin in the patient's upper body. The sympathetic nervous system is the component of the ANS, which is an extensive network of neurons that monitor's the involuntary processes of the body.
Mainly, the sympathetic nervous system monitors the features of the body associated with the fight or flight response like increasing heart rate, mobilizing fat reserves, and discharging adrenaline. Apart from this, the increased heart rate and vasoconstriction will assist in elevating the patient's blood pressure.
Answer:
False
Explanation:
Mendel realized that the F2 had a phenotypic ratio 3:1, meaning 3/4 = 75% were yellow and 1/4 = 25% green.
Mendel observed that the F1 expressed only one of the alternative variants (in this case, only yellow seeds appeared), while the other variant (green) disappeared. Mendel named dominant the expressed variant. Mendel allowed auto pollination and observed that in the second generation, F2, the other disappeared variant reappeared. Both alternative variants were present in the F2. Mendel named recessive the second alternative variant.
Mendel thought that hereditary traits determined by discrete factors were the possible explication for these phenotypes. These factors should have been present in the F1 in pairs. One of them came from one parental plant, and the other factor came from the other plant. These factors then separated again when sex cells were produced, giving two types of gametes, each with only one factor.
Mendel concluded that each individual (plant) has a pair of factors (alleles), one for each trait (yellow and green) and that the pair separates (segregates) during the formation of the gametes. This conclusion is known as the segregation principle (First Mendels´ Low).
Answer:
Processes involving dissolved and particulate organic carbon are of central importance in shaping the chemical character of seawater. Marine organic carbon principally originates in the uppermost 100 metres of the oceans where dissolved inorganic carbon is photosynthetically converted to organic materials.
