The endometrium is the inner lining. The myometrium is the thick middle muscle. The serosa is the outer smooth layer.
Answer:
your answer is b cells are white blood cells that work by producing antibodies, whereas t cells attack foreign invaders directly.

1.1
Meiosis I
The first meiotic division: diploid → haploid
Prophase I: Chromosomes condense, nuclear membrane dissolves, homologous chromosomes join and occurs crossing over.
Metaphase-I: the homologous chromosomes align in the middle of the cell. Spindle fibers from the centrosomes connect to the chromosomes.
Anaphase -I: Spindle fibers contract and split the homologous chromosomes, moving them to opposite poles of the cell.
Telophase -I: Chromosomes decondense; cell divides to form two haploid cells.
1.2 Meiosis II
The second division: separates sister chromatids (these chromatids may not be identical due to crossing over in prophase I)
Prophase II: Chromosomes condense, nuclear membrane dissolves, centrosomes move to opposite poles (perpendicular to before)
Metaphase-II: the chromosomes align in the middle of the cell. Spindle fibers from the centrosomes connect to the chromosomes (at the centromere)
Anaphase-II: Spindle fibers contract and split the sister chromatids, and moves them to opposite poles of the cell.
Telophase-II: Chromosomes decondense,cells divides again to form another 2 haploid daughter cells. Final: 4 new cells.
2. The differences:
Mitosis:
- has 1 division per cycle
- one cell produces 2 new cells
- the genetic information in the mother-cell and the daughter-cells are the same. ( the number of chromosomes is also the same)
- it occurs in somatic cells
Meiosis:
- two divisions per cycle
- one cell when divides produces 4 new cells
- the new cells have different genetic information. mixes the genetic material from the parent cells
- the number of chromosomes of the daughter cells is half of the mother's.
3. Prokaryotic organisms don't divide through mitosis, they use a different process called binary fission. Only eukaryotic organisms, or those whose cells have a defined nuclei, undergo mitosis. Bacteria, for example, are prokaryotic organisms that use binary fission.
4.
It can't occur. Cross over is the exchange of DNA between homologous chromosomes. That will result in recombinant chromosomes during sexual reproduction. It can't occur on different chromosomes because they don't code for the same genes.
5. There are a lot of different theories about that, but it's mostly believed that meiosis must evolve before sexual reproduction. That's because The cell replicates their information first and then divides. Plus the cell does that even though it didn't recombine DNA with another organism (sexual reproduction).
Answer:
either deoxyribose or ribose
Explanation:
i can't see the diagram, but-
- if the diagram shows a single stranded chain of rna, then the answer is ribose
- if the diagram shows a double stranded chain of dna, then the answer is deoxyribose
- uracil and thymine are nucleic acids, not sugars/carbohydrates
For a person born on or after January 1, 1988, to operate a vessel of 10 horsepower or greater on Florida waters, the Florida law requirements follow.
<h3>What are the Florida law requirements?</h3>
Florida law requires a person born on or after January 1, 1988, to operate a vessel powered by a motor of 10 horsepower or greater on Florida waters to meet the following:
- Successful completion of an approved boating safety course.
- Possession of a Boating Safety Education Identification Card issued by the FWC.
- Thus, a legal requirement for a person born on or after January 1, 1988, to operate a vessel powered by a motor of 10 horsepower or greater on Florida waters is possession of a Boating Safety Education Identification Card issued by the Florida Fish and Wildlife Conservation Commission (FWC) after the successful completion of an approved boating safety course.
