Answer:

Energy transfer in ecosystem follows the 10 % law.

Explanation:

In an ecosystem model, the transfer of energy starts with the base level that is from the grass level to the grasshopper that is the primary consumer. This is a plant to animal.

The energy transferred from grasshopper to snake is an example of the animal to animal. The dead and decaying animal may transfer this energy back to the plant through the soil.

During what stage(s) of the cell cycle is the cell actively dividing?

yaroslaw [1]

Answer:

interphase

Explanation:

The cell cycle has two major phases: interphase and the mitotic phase (Figure 1). During interphase, the cell grows and DNA is replicated. During the mitotic phase, the replicated DNA and cytoplasmic contents are separated, and the cell divides.

Which of these would most likely cause a mutation?

ycow [4]

The right answer is B.

Insertion is a genetic mutation characterized by the entrenchment of genetic material in a chromosome. The insertion size varies between a base pair and an entire sector of a chromosome moved to another. In the latter case, part of the genetic data of the first chromosome is erased. This can happen during an uneven jumping.

The embedding of nucleic bases in a gene makes it longer and shifts the reading of its data, which can modify its functioning in a harmful way, especially if the insertion occurs on the exon (fragments of an RNA primary presence in cytoplasmic RNA after splicing).

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.
