Answer:

The primary sequence of development stages consists of many stages. The first step is conception, where a child is conceived by the man and woman in a woman's stomach. You have a zygote, the fertilized egg, which then enters two weeks of rapid cell division and develops into an embryo. The embryo is the developing stage of the human organism, which lasts from about two weeks after fertilization through the second month of the pregnancy. After the embryo, the fetus is developed. It is the developing human organism from 9 weeks after conception to birth. Then the mother gives birth after nine months of conception, where the fetus enters the infancy stage of life.

There are many challenges faced during pregnancy, and one of them is teratogens. Teratogens are viruses or drugs that can damage an embryo or fetus. This is the reason a woman cannot drink alcohol during pregnancy. Teratogens are one of the main reasons that cause miscarriages or stop the development of the fetus.

Newborns have many reflexes when they are born. Some examples of these reflexes are rooting reflex, suck reflex, Moro reflex, and grasp reflex. This reflex starts when the corner of the baby's mouth is stroked or touched. Suck reflex is when the roof of the baby's mouth is touched. Moro reflex, also known as the startle reflex, is when the baby is startled by a loud sound or movement. The grasp reflex is when stroking the palm of the baby's hand, and the baby closes his or her fingers in a grasp. These are some of the reflexes a newborn baby should have.

Answer:

The basic sequence of development stages consist of conception(a child in conceived by the man and woman in the stomach of a woman), Zygotes(the fertilized egg, enters a 2-week period of rapid cell division and develops into an embryo), Embryo(the developing human organism from about 2 weeks after fertilization through the second month of the pregnancy), Fetus(the developing human organism from 9 weeks after conception to birth), Birth(the woman give birth 9 months after conception). Teratogens are viruses or drugs that can damage an embryo or fetus. Teratogens are a reason why woman cannot drink alcohol during pregnancy. Teratogens can cause miscarriages or stop the growth of the fetus. Newborns have many reflexes they are born with, such as the rooting reflex. The rooting reflex occurs when something touches a baby's cheek and the baby turns toward that touch, open their mouth and begin sucking on it. For example when a newborn needs to eat they root for a nipple.

The equilateral triangular cross sections of a solid with base an arch of y = sin(x) on
olga nikolaevna [1]
We can define the base of each equilateral section as b(x) = \sin(x) since this is the distance from the x-axis to the function y=\sin(x).

An equilateral triangle's area can have a function defined solely by the base. Since all sides are equal, the height of the triangle can be found via pythagorean theorem as: A(b)=\frac{1}{2}b\sqrt{b^2+\left (\frac{b}{2} \right)^2} = \frac{b}{2}\sqrt{\frac{5b^2}{4}}

But we know that the base b(x) is a function of x. We also can then state that Area A(b(x)) is also a function of x. Specifically: A(x) = \frac{\sin(x)}{2}\sqrt{\frac{5\sin^2(x)}{4}}.

Then if we integrate the area function A(x) from 0 to pi, we get the total volume:

\displaystyle \int_0^{\pi} A(x) dx = \int_0^{\pi} \frac{\sin(x)}{2}\sqrt{\frac{5\sin^2(x)}{4}} dx = \int_0^{\pi} \frac{\sqrt{5} \sin^2(x)}{4}dx

Anastaziya [24]

Answer:

The correct option is;

B. The photo is a digital representation of the analog painting

Explanation:

The forming of a encoded digital representation of the an object's physically as visually or observed characteristics is known as digital imaging such that there is an implied application of digital processing to the (otherwise analogue) image such as printing, display, storage, or compression of the original image.

With a digital image, copies can be made of the captured image an infinite amount of time while still maintaining the quality of the original copied image.

A painting made by the use of pencils, paints, canvases, and films is known as an analog art or painting.

Sedaia [141]

Answer: vermount and Middle East

Today he is best remembered for his contribution of Man and Nature. The work incorporates observations he made as a youth in Vermont, as well as on his travels in the Middle East. He was the first to suggest that human beings were agents of change, or "disturbing agents." The conventional idea held by geographers of the day, Arnold Guyot and Carl Ritter, was that the physical aspect of the earth was entirely the result of natural phenomena, mountains, rivers, oceans. No one had ever turned to the study of the earth as the home of humankind. Marsh was the first to describe the interdependence of environmental and social relationships.

Explanation:

He was a good diplomat. But we remember Marsh the scholar. He was a student of Scandinavian languages. As a philologist, he wrote an important book on the character of the English language. He was an art collector. As a scientist, he gathered reptiles for the Smithsonian. He was instrumental in the Army's attempt to use the camel in the American Southwest

Over the next few years, Marsh gave a series of lectures on the English language. In 1861, President Lincoln appointed him the first United States minister to the kingdom of Italy, and on April 27, at the age of 60, he set sail, with Caroline, for Europe. In Italy, he found time and capacity for his environmental concerns. He made several fruitful excursions to the Alps where he studied glaciers, moraines, and avalanches. Marsh witnessed Alpine erosion and the devastating contribution of grazing and deforestation, in disastrously accelerating natural erosive processes. In 1862, he began working on the manuscript for Man and Nature, a pioneering study in ecology and conservation.
