Answer:

all I can see is your questions, but a female will have two X chromosomes, a male will have a X chromosome and a Y chromosome. So if Evans has a XY it's a he and if it's an XX it's a she.

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.

Where do male and female gametophytes develop in gymnosperms?

Ksivusya [100]

Gynmosperms are a group of seed producing plants, where the seed are grown on either the leaves (such as a ginko), or scales (such as a pinecone), and gametophytes are found in the same place as seeds, just in a different phase (2 ametes come together to make a seed)

insens350 [35]

The biochemical analysis of different chlorophyll pigments in plants would be most useful in determining D. which plants might have a common ancestor.
The field of biology that deals with the similarities between these plants is called comparative biochemistry. If these plants have similar DNAs, then they are more closely linked in evolutionary terms, and thus it is quite possible they have the same predecessor.
