If a cell with 36 chromosomes undergoes mitosis, how many chromosomes will each of the two new cells have?

andrew11 [14]

Answer: 36 chromosomes

Explanation: Mitosis is a type of cell division that occurs in somatic or body cells. In mitosis, and a cell undergoes division to produce two daughter cells each with the same number of chromosome as the parent cells. Mitosis produces diploid cells and diploid cells are cells that have the same number of chromosomes as the parent cell. Diploid cells have two complete sets of chromosomes. For example in humans, somatic cells with 46 chromosomes undergo mitosis to produce two daughter cells each with 46 chromosomes.

during mitosis and meiosis, DNA is duplicated, chromosomes separate, and cytoplasm divides. how are mitosis and meiosis differen

Misha Larkins [42]

Meiosis results in daughter chromosomes with only half of the original genetic information. mitosis creates a copy of the original cell

Analyze the relationships between the anatomical structures and physiological functions of the muscular system by matching the t

Afina-wow [57]

Answer:

a. Endomysium 8. The layer of connective tissue that surrounds an individual muscle fiber

b. Epimysium 6. The layer of connective tissue that surrounds a skeletal muscle

c. Fascia 3. Connective tissue located between adjacent muscles

d. Fascicle 12. A small bundle of muscle fibers within a muscle

e. Myosin 11. Protein found within a thick filament

f. Perimysium 4. The layer of connective tissue that separates a muscle into small bundles

g. Sarcolemma 5. The plasma membrane of a muscle fiber

h. Sarcomere 7. Unit of alternating light and dark striations between discs (lines)

i. Sarcoplasm 2. The cytoplasm of a muscle fiber

j. Sarcoplasmic reticulum 9. A cellular organelle in muscle fiber corresponding to the endoplasmic

k. Tendon 10. The cordlike part that attaches a muscle to a bone

l. Transverse (T) tubule reticulum 1. Membranous channel extending inward from muscle fiber membrane

Explanation:

A muscle has around it epimysium, which is connective tissue. Inside the epimysium, there are fascicles, and around each of them, there is perimysium. Inside every fascicle, there are muscle fibers, each of them is surrounded by a connective tissue called endomysium. Between every muscle, there is also connective tissue and is called fascia. The connective tissue has vessels and provides support.

The muscle cells are called fibers. They have a membrane, the sarcolemma, a cytoplasm, the sarcoplasm, and a sarcomere, which is the functional unit of the fiber, in other words, it is the structure responsible for the contraction. The sarcomere has different bands made of thick filaments of myosin and thin filaments of actin. They are the light and dark striations that go from disc z to disc z when we observe the sarcomere under a special microscope. The sarcoplasmic reticulum is the place that stores the calcium necessary for the contraction of the fiber, and the transverse tubule reticulum allows the contraction of various fibers since they spread the action potential amongst fibers.

can someone actually help me please The crystals have been dissolved in water. Notice the copper(II) sulphate is the blue soluti

lidiya [134]

The Soduim Hydroxide is just lye. It’s a caustic solution used in lots of things like soap, paper and metal processing.
Copper Sulfate gets its blue color from light energy that excites the electrons. It’s an anti microbial and used with wellness healing. Also has agricultural uses as well. Hope this helps you.
