Answer:
Deltoid
Explanation:
The muscles of the trunk and the muscles of the lower extremity will be used for stability and moving the box across the 2 meters. The muscles of the upper extremity would be used to varying degrees to lift, hold, and lift the box to sternum level and place it in its place and which muscles contribute to the specific portion of the task you intend to study will depend on the magnitude of the load, the frequency the task is completed, the velocity at which the task is completed, the height differential between where the box is lifted from to the height at which the box is placed when the task is completed.
<h2>Functions of plasmodesmata</h2>
Explanation:
- They allow the movement of cells to cells for cytoplasmic connection between different cells
- Plant cells, encompassed as they are by cell dividers, don't get in touch with each other through wide stretches of plasma film the manner in which creature cells can. Be that as it may, they do have particular intersections called plasmodesmata (solitary, plasmodesma), places where a gap is punched in the phone divider to permit direct cytoplasmic trade between two cells.
- Plasmodesmata are fixed with plasma film that is consistent with the layers of the two cells. Each plasmodesma has a string of cytoplasm stretching out through it, containing a much more slender string of endoplasmic reticulum.
- Particles beneath a specific size (the size rejection limit) move unreservedly through the plasmodesmal channel by latent dissemination. The size avoidance limit changes among plants, and even among cell types inside a plant. Plasmodesmata may specifically enlarge (extend) to permit the section of certain huge atoms, for example, proteins, in spite of the fact that this procedure is inadequately comprehended.
The immune system<span> recognizes HIV by its antigen shape. But, just when the immune system recognizes one shape, HIV may multiply and change the shape of its antigen. </span><span>HIV can "hide" from the immune system for a long time. </span><span>When HIV infects a cell the </span>virus<span> may make more viruses and infect more cells or lie quietly in a cell for a long time. If HIV doesn't reproduce, the immune system can't find it and destroy it. </span>HIV destroys the immune system. The Immune system consists of Innate Immunity and Humoral Immunity Innate Immunity is Non-specific Immunity, whereas Humoral Immunity is specific Immunity. T-cells produce Cell-Mediated Immunity and B-cells produces Humoral Mediated Immunity. <span>As HIV destroys more and more helper T cells, the immune system begins to break down. </span> Finally the immune system can no longer kill HIV or any other invading germs and a person infected with HIV is diagnosed with AIDS.
Answer:
B
Explanation:
High and low tides are caused by the moon. The moon's gravitational pull generates something called the tidal force. The tidal force causes Earth—and its water—to bulge out on the side closest to the moon and the side farthest from the moon. These bulges of water are high tides.
Lava is above Earth's surface, magma is below.
