Explain why the lining of the uterus thickens and develops blood vessels between day 5 and day 14 in the menstrual cycle.
enyata [817]

Answer:

The endometrium is the mucous layer that lines the uterus internally. Its function is to thicken during the menstrual cycle to allow the embryo to implant and a pregnancy can take place.Two phases of the endometrial cycle are distinguished: the proliferative phase and the secretory phase. The proliferative endometrium occurs due to tissue regeneration on the first day of the menstrual cycle, where, thanks to the production of estrogen in the ovary, cell multiplication occurs, giving rise to the endometrial glands and more blood vessels.

Explanation:

The first phase, known as the follicular phase, begins on the first day of menstrual bleeding and lasts for about two weeks. During this period, one of the ovules - which are the female reproductive cells - grows and matures within an ovary. At the same time, the ovaries produce hormones that promote the development of the lining of the uterus, called the endometrium. The lining of the uterus, the endometrium, thickens in response to estrogen stimulation, that is, over the days, the endometrium becomes thicker and rich in blood vessels, preparing to receive the egg the moment it is expelled from the ovary. When the ovum matures, around day 14 of the cycle, it separates from the ovary - the ovulation process - and slides down the fallopian tube to the uterus.

choli [55]

Answer:

Answer No 1:

The three ways evolution is determined to have occurred are:

A. Molecular similarities

C. Homologous structures

E. Fossil evidence

Explanation:

Since the theory of evolution became popular, scientists have been looking for similarities and differences among organisms so that they can compare which organisms have a more closer ancestor together as compared to other organisms. Scientists look for molecular similarities, such as the similarities in the proteins and other molecules to depict relations among organisms. Homologous structures is a common term in evolutionary studies in which organisms which are more closely related are known to be more similar. Fossil evidences also help a lot in evolutionary studies.'

Answer No 2:

The correct option is C. the most reproductively successful

Explanation:

Natural selection tends to favour the fittest organism.  In evolution, 'the fittest; means the organism which have the ability to survive in an environment and to pass on its characteristics to its offspring. The organism which is more reproductively successful is considered to be more successful.

Scientists use triangulation to find the epicenter of an earthquake. When seismic data is collected from at least three different locations, it can be used to determine the epicenter by where it intersects. Every earthquake is recorded on numerous seismographs located in different directions.
