Answer:
progesterone
Explanation:
Progesterone, unlike estrogen, has no activity on determining female sexual characteristics. Progesterone activity is to prepare the uterus for possible pregnancy by growing the endometrial lining of the uterus and receiving the fertilized egg and stimulating milk production.
Progesterone is directly responsible for maintaining and sustaining the fetus in the womb, stimulating, during the first two weeks of pregnancy, the fallopian tube and endometrial glands to secrete nutrients essential for the zygote. Uterine contractions are inhibited to prevent the fetus being expelled as it blocks prostaglandin production and decreases oxytocin sensitivity.
Answer:
Because humans has not arrived until 20,000 years ago.
Explanation:
The genus homo has been taken to the emergence with the Homo habilis. Homo sapiens has been emerged around 300,000 to 200,000 years ago.
Holen and colleagues in 2017 discovered 130,000-year-old site in California that contain a a mastodon that had been butchered by humans. Some scientists express skepticism because it has been believed that only humans have occupied North America. The Homo sapiens has not arrived until 20,000 years ago.
In eukaryotes, <em>replication takes place in the nucleus</em> as prokaryotes do not have a true nucleus and <em>replication takes place in the cytoplasm</em>. The nucleus of the eukaryotes is the location where genetic material (DNA) is found; in prokaryotes, the genetic material is condensed in the cytoplasm called the nucleoid. There are multiple replication forks or <em>multiple origins of replication </em>in eukaryotes in contrast to prokaryotes which only has <em>one origin of replication. </em>Lastly, replication in eukaryotes <em>occurs at multiple points along the chromosome; </em>in contrast with prokaryotes where it <em>occurs at just one point on the chromosome.</em>
