Human embryonic development is the development and formation of the human embryo. It is characterized by the process of cell division and cellular differentiation of the embryo that occurs during the early stages of development. In biological terms, the development of the human body entails growth from a one-celled zygote to an adult human being. Choose ALL of the statements that correctly describe stages in human embryology and gestation.

The normal period of gestation is about 40 weeks.

The germinal stage refers to the time from fertilization through the development of the early embryo until implantation is completed in the uterus in about 21 days.

The stages of human development include, in order: zygote, blastocyst, embryo, and fetus

A blastocyst, if untouched and allowed to remain implanted, will eventually develop into a morula.

Changes to the form of the embryo come from differentiation and growth.

Answers

Answer 1

The statements that correctly describe gestation are: the normal period of gestation is about 40 weeks; the stages of this process include: zygote, blastocyst, embryo, and fetus; and changes to the form of the embryo come from differentiation and growth.

The gestation period in humans lasts about 40 weeks and comprises different stages and processes from conception until birth. The main stages of this process include:

Zygote: Fertilized ovum.Blastocyst: Cluster of cells that is the result of the zygote going through cell division.Embryo: Unborn human that is still developing, usually before the 8th week of gestation.Fetus: Unborn human in development after the 8th week of gestation.

Moreover, this process implies differentiation as cells specialize for specific functions, for example, muscle cells or nerve cells, and growth as the number of cells increases and therefore the embryo or fetus increases in size.

Answer 2

Answer:

Many different types of cells make up the human body. Therefore, it is important for cells to differentiate to form different types of tissue. The tissue can then combine to form different organs and systems that carry out specialized functions for the human body.

(excerpt) I achieved the unofficial "smart kid" designation in elementary school, and it was not until years later that I met someone who threatened to depose me from my reign. His name was George, after our nation's first president, and he had been the smartest kid in school during his early academic career as well; but George grew up on the other side of town, so we had really never crossed paths. We were introduced in our biology class, seated at opposite ends of the first row of desks. When our teacher began asking basic questions to test our science knowledge, George and I had not even noticed each other's existence. But when Mr. Hartley inquired about the aardvark's natural habitat, both of us shot a hand into the air. "Africa!" exploded the dual shout, followed by snickering from the rest of the class. I peeked in the direction of the other voice to see George gazing directly ahead, as though he was oblivious to anyone else. Surely, he perceived the awkwardness of this circumstance, and had the abrupt comprehension that there was another "smart kid" in the school! But no acknowledgment crossed his face, and I stared back at my own desk as class continued. When the bell rang and students began jostling out the door, I hung back, thinking that I should at least introduce myself to George. He had waited for everyone else to push out of the classroom as well, and I extended my hand toward him with a smile. "I just wanted to let you know that I plan to outdo you in every class we have together this semester, and every semester until graduation," he said. Without glancing in my direction, George dashed out the door and down the hall toward his locker. I was left in shock at his words, at the audacity of his confidence and conceit. After standing immobile for a few moments, I ducked out the side door of the classroom into the late summer sunshine to comprehend wha.
