Answer:

24 hours

Explanation:

Role of air temperature: Plant respiration occurs 24 hours per day, but night respiration is more evident since the photosynthesis process ceases.

Can 2 species coexist in the same niche? Why or why not?

sweet [91]

In general, one species wins, and one species is eliminated. These experiments gave rise to the competitive exclusion principle: No two species of similar requirements can long occupy the same niche (coexist). In the case of paramecium, the same species always won. Hope This Helps

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.

What helps an animal to look like another animal to stay protected from predators? * (0/1 Point)

VMariaS [17]

Answer: ADAPTIVE COLORATION

Explanation:

Colour and colour patterns play an important role in adaptations of animals. Such adaptive coloration is due to the presence of pigments in cells called CHROMATOPHORES. These cells are involved in coloration and color change which helps an animal to look like another animal to stay protected from predators.

Adaptive coloration may be grouped into :

--> WARNING COLORATION: some animals display bright colours and patterns that announce their presence rather than conceal it. Example is the yellow and black stripes of yellojackets and other wasps which have very painful stings.

--> MIMICRY: colours and patterns are used extensively by mimics. For example, the foul-tasting Actaea butterfly and the poisonous African monarch are mullerian mimics. They resemble each other closely because they have similar colouring and patterns on their bodies.

--> CONCEALING COLORATION: This is used in camouflage. It helps an animal to remain unnoticed by the predator. Certain animals change the colour of their body surfaces to match their environment and so escape detection.
