Answer:
Oxytocin
Explanation:
The release of oxytocin is signaled by the fetal brain about 38 weeks after conception. Oxytocin is also called birth hormone as it stimulates uterine contraction.
The uterine contractions stimulate the release of more oxytocin through a positive feedback loop. Oxytocin stimulates contraction of the smooth muscles in the wall of the uterus which in turn finally leads to childbirth.
Answer:
A
Explanation:
The structure of ATP is such that there are three (3) phosphate moelcules in sequence attached to the 5’ carbon of the ribose sugar ring. The O- groups of each phosphate are close to each other and are negatively charged. They, therefore, repel each ohtehr electrostatically and make ATP very unstable – hence considered weak bonds. ADP is more stable than ATP. Nonetheless, phosphoanhydride bonds between the phosphate have high energy of ΔG of -30.5 kJ/mol. These characteristic make ATP ideal as ane energy currency since it is easy to hydrolyze while producing much energy.
One will fall faster than the other, but only if the gravitational force applied to each one is different
Whale shark reproduction can be by laying eggs that is also called oviparity where the female deposits eggs in the algae or rocks. The embryos formed inside the eggs and feed on the yolk. They can also reproduce through viviparity which means by giving birth just like mammals wherein they are born fully formed. This reproduction process is through the placental link to the eggs wherein the yolk sac grows within a placenta that is connected to the wall of the uterus and gives the offspring the nutrients vital for their growth. Another reproduction process is through Ovoviviparity where eggs are formed inside the mother where the eggs hatch within the oviduct of the female and the young feed on the egg yolk of the yolk sac and the fluids that the walls of the oviduct secrete since the mother does not provide any food directly. Once the eggs are ready, eggs hatch inside the mother and it pups keep getting food from their surroundings until they are fully developed. The number of their offspring and the length of the gestation periods varies according to the species. Probably a female of some species may have only two offspring, but some other species may have between forty and eighty. The small sharks have shorter gestation period compared to large species that last from three to four months or up to more than two years. The large ones reproduce every two years, while the little ones have offspring each year. This is why the reproduction process of whale shark is not known in detail.
