Answer:

For the benefits we have had improvements in communication and transportation which has caused an increase in economic growth.

For the disadvantages this causes (urbanization) will allows people to live in urban areas.

They have totally improve the economic growth, and not only that, but also they made transportation and also communication better. We also have (medical) technology that can help sick ones and people who need help in these aspect's.

But now, the bad side or the (disadvantage) side on this aspect would be of that this causes (urbanization) will allows people to live in urban areas. And also, this technology would be very dangerous to use, (depending) what you're using of course. But this can be seriously hazardous to people, so tis would really be the bad side to this.

I Hope this helps you!

dedylja [7]

Answer:

Explanation:

  • Different vegetation has several unique characteristics.  A hot dry climatic condition is mostly found in desert areas. Desert has few or no precipitation or rainfall.
  • Desert soil is also sandy or rocky, more reason why it is so important to find plants that can survive under such conditions and also help against soil erosion. Plants with long roots such as cactuses are preferred in this region.

Explain how the shape of a protein molecules can affect its function
kherson [118]

Solution:

The function of a protein is determined by its shape.

The shape of a protein is determined by its primary structure (sequence of amino acids).

The sequence of amino acids in a protein is determined by the sequence of nucleotides in the gene (DNA) encoding it.

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.
