Answer:

All of the above

Explanation:

CAM leaves the stomata closed during the day. They are most common in hot, arid environments. During the night, when their stomata are open, these plants take up CO2 and incorporate it into a variety of organic acids.

Do you think it is possible for scientists to incorporate chloroplasts into the skin cells of humans? What would this mean for h

Alisiya [41]

Similarly to mitochondria on which the animals and fungi rely upon, the chloroplasts are the solar-power plants of the plant cell. With the advancement in the field of genetics and biotechnology, it may be feasible for scientists to incorporate chloroplasts into human skin cells. However, there may be few issues, which the human beings would have to encounter with, these are as follows:

1. The immune system of the humans may attack the chloroplasts, but maybe they would be safe if they are present within the cell.

2. As the skin of the humans would be undergoing the process of photosynthesis, then they would have to be in green color, thus, the melanocytes of the skin would have to be engineered in order to generate another pigment.

3. The humans may get skin cancer and sunburns when they would be out feeding on sunlight, that is, the ultraviolet part of the sunlight would cause the destruction of the living cells.

4. In order to undergo the reaction of photosynthesis, the humans would require more water than usually required by a normal human being, and this could be a disadvantage in a desert surrounding.

5. The process would not help to generate much energy for an active species like humans, as the daily energy requirements for a human being would be attained by absorbing around 10000 kJ of energy, that is, around 150 hours in a day of sitting in the Sun, which is impossible.

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.
