What forms the corpus luteum and what hormones does it secrete?
The corpus albicans becomes the corpus luteum after ovulation and secretes estrogen and
progesterone.
The cumulus oophorus becomes the corpus luteum before ovulation and secretes luteinizing
hormone and estrogen to promote oocyte development.
The follicular cells become the corpus luteum after ovulation and secrete follicle stimulating
hormone and estrogen to promote oocyte development.
The Graafian follicle becomes the corpus luteum after ovulation and secretes estrogen and
progesterone.
The corpus albicans becomes the corpus luteum after ovulation and secretes estrogen and
progesterone.
The cumulus oophorus becomes the corpus luteum before ovulation and secretes luteinizing
hormone and estrogen to promote oocyte development.
The follicular cells become the corpus luteum after ovulation and secrete follicle stimulating
hormone and estrogen to promote oocyte development.
The Graafian follicle becomes the corpus luteum after ovulation and secretes estrogen and
progesterone.
Solution
Answer: D: the graffian follicle becomes the corpus luteum after ovulation and secretes estrogen
and progesterone.
The degenerating corpus luteum is called corpus albicans.
The corpus luteum secretes large quantity of progesterone and moderrior piyate quantity of
estrogen.
Leutinizing hormone and follicle stimulating hormone are from anterior pituitary..
What made the Later Roman Economy so unstable (Bennette, Medieval E.pdf
1. What made the Later Roman Economy so unstable? (Bennette, Medieval Europe )
Solution
The later Roman Economy was so unstable because of some couple of economic reasons.The
reason is mainly financial. Commodus taxed the senators and was generous with the others.
Likewise, Nero was popular with the lower classes. The main financial and economic reasons
behind the unstability are as follows:
Inflation
Nero and other emperors debased the currency in order to supply a demand for more coins. By
debasing the currency is meant that instead of a coin having its own intrinsic value, it was now
the only representative of the silver or gold it had once contained.By the time of Claudius II
Gothicus (268-270 A.D.), the amount of silver in a supposedly (100%) silver denarius was only
.02%.This led to or was severe inflation.The Roman Empire acquired money by taxation or by
finding new sources of wealth, like land. However, it had reached its furthest limits by the time
of the second good emperor, Trajan, during the period of the high empire (96-180), so land
acquisition was no longer an option. As Rome lost territory, it also lost its revenue base.
Land
Rome's wealth was originally in the land, but this gave way to wealth through taxation.During
the expansion of Rome around the Mediterranean, tax-farming went hand-in-hand with
provincial government since the provinces were taxed even when Romans proper were not. Tax
farmers would bid for the chance to tax the province and would pay in advance. If they failed,
they lost, with no recourse to Rome, but they generally made a profit at the hand of the
peasants.Keith Hopkins says that the diminishing importance of tax-farming at the end of the
Principate was a sign of moral progress, but also meant the government couldn't tap private
corporations in the event of an emergency.The means of acquiring crucial monetary funds
included debasing the silver currency (seen as preferable to increasing the rate of taxation, and
common), spending reserves -- depleting the imperial coffers, increasing taxes (which was not
done during the period of the high empire), and confiscating the estates of the wealthy elite.
Taxation could be in kind, rather than coinage, which required local bureaucracies to make
efficient use of perishables, and might be expected to produce reduced revenue for the seat of the
Roman Empire.Once the wealthy and powerful were no longer either rich or powerful, the poor
had to pay the bills of the state.These bills included the payment of the imperial guard and the
military troops at the empire's borders.
Feudalism
2. Since the military and the imperial guard were absolutely essential, taxpayers had to be
compelled to produce their pay. Workers had to be tied to their land.To escape the burden of tax,
some small landowners sold themselves into slavery, since slaves didn't have to pay tax and
freedom from taxes was more desirable than personal liberty.
