6, how often does an egg cell leave an ovary, in an adult woman
7, how often does menstruation happen, in an adult woman
Answers
Answer:
°•°
Explanation:
1.fallopian tube
2.an unborn or unhatched offspring in the process of development, in particular a human offspring during the period from approximately the second to the eighth week after fertilization (after which it is usually termed a fetus)
3.First, the zygote becomes a solid ball of cells. Then it becomes a hollow ball of cells called a blastocyst. Inside the uterus, the blastocyst implants in the wall of the uterus, where it develops into an embryo attached to a placenta and surrounded by fluid-filled membranes.
4.Eggs live in ovaries, and the hormones that control your menstrual cycle cause a few eggs to mature every month. When your egg is mature, it means it's ready to be fertilized by a sperm cell. These hormones also make the lining of your uterus thick and spongy, which gets your body ready for pregnancy.
5.The fertilized egg attaches to the lining of the uterus. The placenta then develops. The placenta transfers nutrition and oxygen to the fetus from mother. If the egg does not become fertilized, the lining of the uterus (endometrium) is shed during menstruation.
6.The egg cell travels down the fallopian tube into the uterus. The moment the egg cell leaves the ovary is called ovulation. Once a girl has had her first monthly period, ovulation usually occurs once a month
7.The average menstrual cycle is 28 days long. Cycles can range anywhere from 21 to 35 days in adults and from 21 to 45 days in young teens. The rise and fall of levels of hormones during the month control the menstrual cycle.

A pair of identical twins develop leukemias, where immature white blood cells proliferate uncontrollably. In each case, the cancer cells analyzed from identical twins displayed an identical chromosomal mutation and this critical mutation was not found in the twins normal cells. The twins developed leukemia at different times in their lives. What is the best explanation for the origin of this chromosomal mutation
Answers
Answer:
The chromosomal rearrangement resulted from a rare somatic mutational event that occurred in utero
Explanation:
Leukemia is a progressive type of cancer where immature white blood cells (leukocytes) proliferate uncontrollably. Next-generation sequencing (NGS) technologies have shown that somatic mutations are relatively common in different types of leukemia such as, for example, acute myeloid leukemia (AML). Moreover, identical twins are developed from one fertilized egg (ovum) that splits and develops into two identical individuals that share all of their genes (i.e., they have exactly the same genetic information). In this case, it is expected that leukemogenesis was initiated in the utero by the occurrence of a chromosomal rearrangement and proceeded early during development as distinct clonalities. In addition, the fact that identical twins developed leukemia at different times in their lives also indicates that this malignancy wasn't caused by only one mutation, but instead it was triggered by multiple mutational events (i.e., leukemia is a multistep cancer caused by secondary genetic changes).

What does the data reveal about the relationship(s) between the impactor's mass and crater depth?
Answers
Answer:
For each ball, the crater diameter increased as the height of the ball drop increased. My conclusion is that crater diameter increases with increasing mass. Also as the height of the ball increases, so does the crater diameter. Thus crater diameter is proportional to the mass and velocity of the impactor.

Non vascular plants are quite commin in the forests along the coast of Norther California but are relatively rare in the ecosystems around Davis in the Central Valley. What aspects of the life cycle of these plants make it difficult for them to reproduce on our area
Answers
Answer:
The Central Valley of northern California is a region where there is little water supply, while nonvascular plants cannot efficiently store water and they have primitive traits that are dependent on water for reproduction.
Explanation:
The Central Valley of northern California is characterized to have little natural precipitation/snowmelt during the dry summer months. In addition, California's climate also has extended periods of drought. On the other hand, non-vascular plants such as mosses and liverworts, are a type of plant that lacks vascular tissues (xylem and phloem), and they also lack true roots, stems, or leaves. These plants cannot efficiently absorb and store water (which fundamental for survival), and thereby the success of these plants in establishing and reproducing in the ecosystems of the Central Valley is limited to their physiological tolerance to desiccation. Moreover, non-vascular plants may also exhibit primitive traits related to their reproductive cycle (e.g., a flagellated sperm) that are dependent on water for reproduction.

The fossil presence of anatomically modern humans in ________ demonstrates that our ancestors were capable of substantial water crossings by 40,000 years ago.
Answers
Answer:
The correct answer is - Africa.
Explanation:
Scientists found the fossils of modern humans called Mota an ancient man who lived around 40000 to 45000 years ago in Ethiopia. It was the first DNA isolated from Africa.
This DNA sample says that the Europeans have 6% of the DNA of this modern human, which suggests that there was substantial migration of people into Africa from Europe and the middle east by water crossings.
