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.

Which document made provisions for federal authority in the west but prohibited the spread of human bondage?.
Amanda [17]

Missouri Compromise made provisions for federal authority in the west but prohibited the spread of human bondage.

What is Missouri Compromise?

  • The Missouri Compromise Act, passed by the US Congress in 1820, admitted Missouri as the 24th state to the Union.
  • Northern congressmen attempted unsuccessfully to attach amendments preventing further slaveholding after the area requested sovereignty without constraints on slavery.
  • When Maine (which was once a part of Massachusetts) applied for statehood, Henry Clay brokered a deal that saw Maine admitted as a free state and Missouri admitted as a slave state.
  • Slavery was subsequently outlawed in areas north of Missouri's southern boundary.
  • Clay's solution highlighted the sectional divide while appearing to resolve the slavery-extension issue.

How lond does it take harry to go 0.7 miles if he can run 12 miles in 6 minutes
irga5000 [103]

Answer:

Harry will take 21 seconds.

Explanation:

Speed of Harry = \frac{\text{Distance covered}}{\text{Time taken}}

Since, Harry covers 12 miles in 6 minutes,

Then the speed of Harry = \frac{12}{6}

                                          = 2 miles per minute

If he covers 0.7 miles then time taken by him will be,

Time taken = \frac{\text{Distance covered}}{\text{Speed}}

                   = \frac{0.7}{2}

                   = 0.35 minutes

                   ≈ 0.35 × 60 seconds

                   = 21 seconds

How might genotype frequencies of alleles for body size change under directional selection? see section 23.3 ( page 463) ?
Zepler [3.9K]

The directional selection is the type of natural selection, in which an extreme phenotype is  promoted due to the changes in the environment. This causes the changes in the allele frequency  and the shifting of the phenotype in a particular direction. In this condition, one of the extreme phenotypes are promoted, which result in the shifting of genotypic frequency either of the homozygous characteristics.
