Answer: Node

Explanation:

Cladograms are a graphical representation of the evolutionary relationship between organisms. These are usually shown as branches from a central point, which represents a common ancestor. In rooted cladograms, the branches are shown relative to the time elapsed since evolving from a common ancestor joined at the node, or point of divergence.

Evolution typically occurs after accumulating mutation, and natural selection of beneficial traits that confer greater chances for survival.

Describe two ways in which the above law protects citizens against human trafficking
user100 [1]

Answer:

The law in question is not included so I will include tow different laws and how they protect people from human trafficking.

1. The Victims of Trafficking and Violence Prevention Act (TVPA).

This Act made human trafficking a Federal crime while also establishing rules on how to prosecute human traffickers and getting the victims of trafficking reintegrated into society and protected. Under this Act therefore, citizens are protected because the law <u>would act as a deterrent to a lot of would-be traffickers. </u>

2. The Mann Act of 1910.

Under this Act, it is a crime to make promises to people such that they cross state lines and are then involved in activities they did not sign up for - this is a definition of human trafficking so this law protects citizens from that.

1). Xeroderma pigmentation (XP): XP can be defined as a genetic disorder, due to mutations in genes involved in repair processes. It leads to severe sunburn and freckling due to sun exposure, dry skin and skin pigmentation. People having xeroderma pigmentation are prone for skin cancer.

Which events in the monthly female reproductive cycle occur simultaneously?
Anika [276]

Answer:

A. Menstruation and the estrogen surge

Explanation:

The events that occur simultaneously in the monthly female reproductive cycle are menstruation and estrogen increase.

The menstrual cycle lasts about 28 days and is controlled by the secretion of gonadotropins (FSH and LH), secreted by the pituitary, and estrogen and progesterone, produced by the ovaries. The first day of the cycle corresponds to the first day of menstruation. During menstruation, levels of sex hormones in the blood are low. By the sixth day, the pituitary again secretes a greater amount of follicle stimulating hormone (FSH).

Therefore, in this first phase of menstruation, the pituitary secretes the hormone FSH, which, as the name implies, will stimulate the development of ovarian follicles. In turn, the follicles produce estrogen, which stimulates the growth of cells in the uterine inner wall, the endometrium, which becomes thicker and well-vascularized. These are changes that prepare the uterus for the implantation of an embryo, ie a pregnancy.

The high concentration of estrogen in the blood stimulates the secretion of luteinizing hormone (LH). LH induces ovulation, which occurs around the 14th day of the cycle. Next, the LH induces the rupture of the ovarian follicle and the consequent release of the egg, besides leading to the development of the corpus luteum. The corpus luteum produces progesterone, which will assist in maintaining the endometrium until the end of the menstrual cycle.

Is Scorpio a water sign?
gregori [183]
Cancer, Scorpio and Pisces are the water signs of the zodiac. Just like it sounds, water signs are very fluid and constantly wavering. They swim back and forth between reality and their imaginations. Those who are these signs constantly have a change in emotions and waver back and forth about their decisions.
