Answer:

Hydrostatic skeleton

Exoskeleton

Endoskeleton


Explanation

Hydrostatic skeleton

Many animals have a water-based skeleton, or hydrostatic skeleton. Hydrostatic skeletons do not contain hard structures, such as bone, for muscles to pull against. Rather, the muscles surround a fluid-filled body cavity. In a worm, for example, movement occurs when muscle cells contract, and the contractions squeeze internal fluid (the hydrostatic skeleton) against the skin, causing the worm to stiffen and the body to shorten and widen. The squirming motion of a worm also depends on a hydrostatic skeleton.

Exoskeleton

A second type of skeleton, the exoskeleton, exists in arthropods and mollusks. In mollusks, the exoskeleton is a hard, protective outer covering. An example is a clamshell; when a clam’s muscles contract, they close the shell rapidly, creating a spurt of water that propels the clam. In arthropods, the exoskeleton also provides protection and movement. Usually, wings are attached by muscles in the hard body surface, which provides a foundation for the muscle contractions. Muscle contractions raise and lower the wings, allowing flight.

Endoskeleton

Vertebrates have an internal skeleton called the endoskeleton, a framework of bones and cartilage (see Figure 27-1) that serves as a point of attachment for muscle. The endoskeleton thus transmits the force of muscle contractions. The endoskeleton also provides support for the body (for example, the legs) and protection (the skull).

Bone contains concentric rings of tissue in which bone cells called osteoblasts produce the inorganic materials (fibers and matrix) of bone. Much of this material is calcium phosphate, formed from calcium and phosphorus delivered by the blood. Living, mature bone cells called osteocytes are also located in the bone. Bone-destroying cells called osteoclasts break down bone, thus providing a turnover of bone material needed in other areas. The combination of bone cells and bone tissue comprises a unit called a Haversian system. Blood vessels and nerves also exist within the Haversian system.

Bones come together to form a joint, which may be immovable, such as in the sutures of the skull, or movable, such as in the joints of the elbow and shoulder. In a movable joint, a capsule of synovial fluid provides lubrication. Tough, fibrous tissues, known as ligaments, link bones to one another. Connective tissues, called tendons, attach muscles to bones.

The "time-zone fallout" problem is most likely to discourage voter turnout in the

I think It’s the east

The "time-zone fallout" problem is most likely to discourage voter turnout in the East. The phenomenon known as "time-zone fallout" describes how presidential election polls in the East close before polls in the West. Thus, option C is correct.

Before all of the voters in the West have cast their ballots, the press frequently forecasts the outcome of a contest based on early returns from the East. Some individuals worry that these rumors may have stopped Western voters from casting voting or may have impacted their choices.

The gradual expansion of voting rights, from initial limitations to white male property owners aged 21 or older in the early years of the independence of the nation to all citizens aged 18 or older in the middle of the 20th century, has determined the historical trends in voter turnout in the United States election for president.

Therefore, option C is the ideal selection.

How was the decision in Dred Scott v. Sandford changed? Be sure to provide the name and a brief description of the congressional act, constitutional amendment, or subsequent Supreme Court ruling that overturned the decision

Answers

Answer:

Explanation:

In Dred Scott v. Sandford (argued 1856 -- decided 1857), the Supreme Court ruled that Americans of African descent, whether free or slave, were not American citizens and could not sue in federal court. The Court also ruled that Congress lacked power to ban slavery in the U.S. territories. Finally, the Court declared that the rights of slaveowners were constitutionally protected by the Fifth Amendment because slaves were categorized as property.

In this case, the rights of slave owners to transport their captives into western areas were protected. The Missouri Compromise of 1820, which had restricted the practice of slavery in a few American territories, was also declared invalid by the court.

What was  Dred Scott v. Sandford case?

On March 6, 1857, the U.S. Supreme Court ruled in the Dred Scott decision that Dred Scott, an enslaved man, was not entitled to independence since he had lived in a free state and territory.

According to the courts, no one with African ancestry will ever be able to vote in federal elections or become a citizen of the United States.

The 13th and 14th amendments to the Constitution, which prohibited slavery and declared all people born in the United States to be citizens, overturned the Scott v. Sandford judgment, which many legal scholars believe to be the worst ever made by the Supreme Court.

The ruling added that Congress lacked the power to outlaw slavery on government property. The nation advanced one step closer to the Civil War as a result of this decision.
