7 0

Answer:

An aquatic ecosystem includes freshwater habitats like lakes, ponds, rivers, oceans and streams, wetlands, swamp, etc. and marine habitats include oceans, intertidal zone, reefs, seabed and so on. The aquatic ecosystem is the habitat for water-dependent living species including animals, plants, and microbes.

Where do you think magna comes from?
Softa [21]

Answer:

Magma is primarily a very hot liquid, which is called a 'melt. ' It is formed from the melting of rocks in the earth's lithosphere, which is the outermost shell of the earth made of the earth's crust and upper part of the mantle, and the asthenosphere, which is the layer below the lithosphere.

white blood cells; formed elements involved in body protection that take part in inflammatory and immune responses are:
svetoff [14.1K]

Neutrophils They kill and then digest the bacteria and the fungi. They are the most numerous type of the white blood cell and your first line of the defense when the infection strikes.

A high level of neutrophils in the blood is called neutrophilia. This is a sign that your body is infected. Neutrophilia can indicate many underlying conditions and factors, including: Infection, possibly bacteria. They capture and destroy invading microbes through phagocytosis and intracellular degradation, release of granules, and formation of neutrophil extracellular traps upon detection of pathogens. Neutrophils are also involved as inflammatory mediators. What is the most common cause of high neutrophils? infection. This is the most common cause of high neutrophil counts. Most bacterial infections cause elevated neutrophil counts, but not all. Viral infections generally do not cause neutrophilia, but it can occur early in the infection.

Place the following events of muscle excitation in the correct order.
svetlana [45]

An motion potential in the presynaptic cell activates calcium channels. Ca+ triggers the discharge of Acetylcholine through exocytosis. Ach binds its receptors in the postsynaptic membrane, opening Na+ channels. The Order is 4, 3, 5, 1, 2.

The principal frightened system generates an motion potential that travels to the goal activating the calcium channels ⇒ event (4)

Calcium triggers vesicles fusion to the presynaptic membrane. By exocytosis, vesicles release the neurotransmitter -Acetylcholine- into the synaptic space ⇒ event (3)

Once there, Ach binds to its receptors on the postsynaptic membrane of the skeletal muscle fiber, causing ion channels to open ⇒ event (5)

Positively charged sodium ions move the membrane to get into the muscle fiber (sarcoplasm) and potassium leaves the cell ⇒ event (1)

The distinction in charges, resulting from these ions' transport, positively charges the fiber membrane. The postsynaptic cell depolarizes ⇒ Event (2)

The motion potential enters the t-tubules depolarizing the internal part of the muscle fiber. Contraction initiates while the motion potential depolarizes the internal part of the muscle fiber. Calcium channels spark off in the T tubules membrane, releasing calcium into the sarcolemma.

At this point, the muscle is at rest, and the tropomyosin is inhibiting the appeal strengths between myosin and actin filaments. Tropomyosin is obstructing binding sites for myosin on the skinny filament.

When calcium enters the sarcolemma, it binds to troponin C, and troponin T alters the tropomyosin role through shifting it and unblocking the binding sites.

Myosin heads be a part of the uncovered actin-binding points forming move-bridges, and whilst doing so, ATP turns into ADP and inorganic phosphate, that's released.

Myofilaments slide impulsed through chemical energy accumulated in myosin heads, generating a strength stroke. The strength stroke initiates while the myosin move-bridge binds to actin. As they slide, ADP molecules are released. A new ATP hyperlinks to myosin heads and breaks the bindings to the actin filament.

Then ATP splits into ADP and phosphate, and the energy produced is gathered in the myosin heads, which begins offevolved a new binding cycle to actin.

Finally, Z-bands are pulled towards every other, and the sarcomere and the I-band get shorter, generating muscle fiber contraction.

According to those steps, the appropriate order of activities is 4, 3, 5, 1, 2.
