Answer:

The places where one can gather the outcomes of the experiment in an organized and neat chart are known as data tables. The data will be utilized to develop charts or to make determinations regarding the influence, which the independent variable exhibited on the dependent variable.

Apart from the data, personal notes can be supplemented to the data table to offer knowledge, which may assist to predict the outcome of the experiment. The data generally comes in two kinds, that is, qualitative and quantitative.

The data tables assist one to maintain the information in an organized manner. If one is gathering data from the scientific research or from an experiment, saving it in a data table will make it easier for assessing it afterward.

By organizing data, a scientist can more easily interpret what has been observed. ... Since most of the data scientist collect is quantitative, data tables and charts are usually used to organize the information. Graphs are created from data tables. Hope this helps

Answer:

B. Mixture

Explanation:

Steel is an example of a mixture. It's known as an alloy of iron mixed with carbon. The carbon helps to improve its strength and its resistance to fracture. Other percentages of chromium, nickel, vanadium, etc can be added in order to obtain steels of a desired hardness, resistance to corrosion, etc. Due to its high tensile strength, it is used in tools, ships, cars, electrical appliances, weapons, etc.

Please note: I answered this question with my knowledge of steel and to the best of my ability. The passage that was referred to in the excerpt wasn't added for me to use.

Beginning with the flow phase, arrange the biochemical processes in the order in which they occur during the menstrual cycle.

Svet_ta [14]

The right order are :

6. High progesterone levels ...

4. The endometrium lining breaks down ...

1. FSH and LH stimulates ...

5. Rising estrogen levels suppress FSH production ...

3. A spike in LH causes follicle to rupture.

2. A breakdown of corpus luteum ...

The menstrual cycle is divided into 2 phases:

Phase 1: the estrogenic or follicular phase (14 days)

The ovarian follicules each house an egg. They continue to grow thanks to the hormone FSH (follicle stimulating hormone) secreted by the pituitary gland, a gland at the base of the brain. But in the end, only one follicle matures. The others will then disappear.

The ovaries produce estrogen that will allow the endometrium to thicken to accommodate an egg in case of fertilization.

The estrogen level gradually increases in the blood and triggers the sudden release of luteinizing hormone (LH), which has been secreted and stored by the pituitary gland. Under the action of this hormone, the dominant follicle breaks and delivers an egg: it is the moment of ovulation.

The oocyte initiates the descent of the fallopian tube to the uterus for 3 or 4 days. It is fecundable for about 24 hours. Then, and if he has not met sperm, he degenerates.

Phase 2: the progesterone or luteal phase

The second phase of the menstrual cycle begins after ovulation and lasts 2 weeks.

Under the action of the LH, the follicle that released the egg turns into a yellow body. This temporary cell structure produces estrogen and a large amount of progesterone. This hormone acts on the thickening of the uterine lining, which is enriched with nutrients.

Progesterone production peaks about 8 days after ovulation and then declines as the pituitary stops secreting LH. The corpus luteum deteriorates around the 23rd day, until the 28th day. This also causes a drop in estrogen levels.

This hormonal variation influences the state of the endometrium. As it does not receive so much blood and oxygen, the upper wall of the mucosa gradually degenerates and is evacuated by the vagina in the form of bleeding, what is called menstruations.
