Through the application of radiometric dating techniques, the relative and absolute ages of rocks and fossil records offer proof of the earth's geographic past.

The geologists' dating techniques are typically based on radioactive dating.

To date the history of such events, credible sources of information such as the natural decay of the elements or compounds contained in the artifacts are used.

For instance, Red Rock Canyon is a region of geologic significance to all people.

The Red Rock Canyon National Conservation area is a beauty that took millions of years to create. Red Rock Canyon was discovered at the bottom of an ocean basin around 500 million years ago.

This ocean basin has accumulated limestone that is home to marine life fossils. The Aztec Sandstone has been found to contain the footprints of two-footed, meat-eating dinosaurs.

There were also uncovered the footprints of small creatures including spiders, scorpions, early mammals, and proto-mammals. Red Rock Canyon's fossils and rock formations provide proof of the planet's geologic past.

Describe the changes that take place during the menstrual cycle from Day 5-13 to the following:
erastovalidia [21]

Answer:

Between days 5 and 13 of a woman's menstrual cycle, an unfertilized egg in ovary prepares its development and maturation within the follicle, while the lining of the uterus -the endometrium- progressively enlarges.

Explanation:

Under normal conditions, a woman's menstrual cycle lasts 28 to 30 days, during which time both hormonal and physiological changes occur as part of the reproductive process.

Menstruation occurs as a result of the shedding of the endometrium, which had previously developed to facilitate the implantation of a possible pregnancy. This phase usually lasts five days and is characterized by genital bleeding.

From the fifth to the 13th day, a woman's reproductive system undergoes changes in preparation for possible fertilization and pregnancy:

  • <em>The unfertilized egg</em><em> is found inside the ovarian follicle, maturing before its imminent release, under the influence of follicle-stimulating hormone (FSH). The maturation of a few follicles occurs simultaneously, but only one will reach the necessary maturity to allow the release of the egg. </em>
  • <em>The lining of the uterus</em><em>, called the endometrium, receives signals from the hormone estradiol -produced by the mature ovarian follicle- and induces proliferation and thickening of the endometrium.</em>

Approximately on the 15th day of the menstrual cycle, the egg is released and it is the time when it can be fertilized by a sperm to produce the zygote, which will start a pregnancy in women.

When working with a microscope to focus on a specimen identify one safety issue to consider when switching to a higher power obj
omeli [17]

Answer:

The correct answer is - One should always look on the side of the microscope so they don't break the slide and use fine adjustment knob only in order to avoid damage.

Explanation:

At the point when an example is in the center at high force, there might be 1-2 millimeters of room between the high power lens and the slide. On the off chance that you check from the side and see more space than that, you are not even close to having the example in the center.

In the event that you need a particular cell in the lower power field of view to be obvious in the high power field of view, it must be in the focal point of the low force field before you switch up to high power!  

One should always look on the side of the microscope so they don't break the slide and use fine adjustment knob only in order to avoid damage.
