How many calories are equivalent to 1 pound of body fat?

Biology
1 answer:
aksik [14]2 years ago
7 0
<span>Because 3,500 calories equals about 1 pound (0.45 kilogram) of fat, you need to burn 3,500 calories more than you take in to lose 1 pound. So, in general, if you cut 500 calories from your typical diet each day, you'd lose about 1 pound a week (500 calories x 7 days = 3,500 calories).


Hope help!</span>

Which component of the thin filament makes the main string of pearls portion of the filament?
Brums [2.3K]

jagged line of protein discs which attach thin filaments from end to end,  trace the boundary where sarcomeres connect, thick  type of smallest muscle unit: composed of staggered arrays of many myosin molecules which interact with actin when calcium is present.

With all his gear Neil Armstrong wait 360 pounds on earth when he landed on the moon he weighed 60 pounds why
OlgaM077 [116]

Because the moon is significantly smaller than earth,

Its gravitational pull is also smaller and weaker.

So he weighed much less on the moon than he did on earth because of the change in gravity

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.

An 8-month-old infant is eating and suddenly begins to cough. The infant is unable to make any noise shortly after. You pick up
lesya [120]

Answer:

The five-and-five first aid action recommended by the red cross

Explanation:

When an infant is choking and becomes unresponsive, the five-and-five approach is recommended as a first aid treatment to dislodge the material blocking the airway.

<em>The five-and-five action involves alternation between giving the subject five back blows and five abdominal thrusts until the the choking material is dislodged or the subject becomes unconscious.</em>

If the infant becomes unconscious, CPR should be performed and further help should be sought.
