The study of the nature, structure, function, and diseases of the muscles is:
ICE Princess25 [194]
That would be myology. Myology is the study of the muscular system, wlong with its nature, structure, functions and diseases. It mainly deals with the three types of muscles found in the human body: skeletal muscles, smooth muscles, and cardiac muscles. Muscles are also categorized depending on whether or not they are voluntary or involuntary. Myology is concerned with the study of all this and much more.

If ssb is not present during dna replication, what would you expect to see?
In-s [12.5K]
A. SSB prevents reannealing of the separated strands, so strands would quickly reanneal and DNA replication cannot proceed.

Single-stranded binding proteins, or SSB, appear on the strands to separate the strands. Without a separation force, the strands would simply bind back together through hydrogen bonding.

The two most common sites of bone marrow collection in an adult are the _______________ and _________________.
Dahasolnce [82]

Answer: Pelvic and sternum

Explanation:

bone marrow biopsy is a procedure that is used to obtain bone marrow usually with syringe for evaluation of various blood cells( leucocytes, erythrocytes ) and also for examination for different blood disesases such as leukemias and lymphomas and diagnose some genetic conditions. The common site for a bone marrow biopsy is the large pelvic bone near the hip and also some samples taken from the sternum (breastbone).

A bone marrow examination or test consists of two separate tests that are done at the same time namely:

1. Bone marrow aspiration that helps collect sample of the liquid portion of the bone marrow

2. Bone marrow biopsy that obtains a sample of the solid material.

What is the island of Hispanola named today?
12345 [234]


The Correct  answer is C.

The Island of Hispaniola is the second largest island in the Caribbean, at 29, 237sq miles. Haiti occupies about 1/3 of the Island while the Dominican Republic controls the balance of the land.

Christopher Columbus claimed Hispaniola in 1492, declaring it  "the most beautiful island in the world".  It later became the launching base for the Spanish conquest of the Caribbean, as well as the American mainland. 

The western third of the island became known as Haiti in 1804 and while the remainder became known as the Dominican Republic in 1844.

15. Makes up the structure of the ribosomes (rRNA)

16. Substances produced by the Golgi bodies (Secretions)

17. The fibers which direct the even distribution of chromosomes (Spindle)

Explanation:

Plant cells: (1,3,5,6)

Plant cells differ from animal cells in several ways.

<em><u>Cell wall:</u></em> One of the most defining one is plant cells have cell walls. These cell walls are rigid and they cover the plasma membrane of the plant cell. Cell walls have 3 layers and the outermost one is called the middle lamella, which is the cell cement. It acts like a cement because it is what holds one plant cell and the adjacent cells together. The middle lamella is made up of pectin.

The cell wall also has layers made up of <em><u>cellulose, </u></em>which happens to be a macromolecule as is the most abundant of its kind on Earth. They form bundles called microfibrils.

<em><u>Chlorophyll: </u></em>Chlorophyll are molecules found in plant cells that play a role in food production in plants. Chlorophyll absorbs sunlight which is used in the process of food making called photosynthesis, along with other elements like water and carbon dioxide. Also chlorophyll gives the green pigmentation of plants.

<u><em>Chloroplast:</em></u> Chlorophyll are encased in an organelle called chloroplast. Chloroplasts are where photosynthesis takes place. They are found in the leaves of plants. Because they use chlorophyll, the are also green.

Other parts of a cell: (4, 9,11.15, 16, 17)

Both plant and animal cells also have similar organelles.

<em><u>Endoplasmic Reticulum (ER):</u></em> There are two types: smooth endoplasmic reticulum(SER); and rough endoplasmic reticulum(RER). The SER acts like a storage unit for lipids and steroids. They also help in the production as well. RER is a pckaging and synthesis area. It is rough because they have ribosomes on them.

<em><u>Ribosomes:</u></em> Ribosomes are small organelles in the cell that are partly made up of rRNA or ribosomal RNA. They play an important role in protein synthesis. They help translate the DNA code that the mRNA transcribed to determine what type of protein will be formed.

<em><u>Golgi Apparatus:</u></em> Also known as the golgi complex, is an organelle in the cell that serves as a sorting and packaging area. It collects simple molecules and packages them into more complex molecules which would be stored if the cell would need it, or it will be sent out of the cell. These complex molecules are packed into vesicles. A transition vesicle is made from the protein in the ER is transported to the golgi apparatus, which then processes its contents. It then releases a secretory vesicle, that is then brought to the cell membrane.

<em><u>Centrioles: </u></em> Centrioles are small, cylinder-shaped organelles that aid in cell division. They are made up of the protein, tubulin. These centrioles produce <em><u>spindles </u></em>or spindle fibers that pull on the chromosomes during cell division and split them up.
