Eddi Din [679]

Answer:

Bacteria.

Explanation:

These are DNA that formed closes loops.

They have no ends.

A typical example is plasmids of bacteria., circular bacteria chromosomes,

In viruses example are ccc DNA (circular closed circular DNAf) formed by viruses.

Suppose you have made the following hypothesis:The greater the height from which you drop a ball, the faster the ball will be tr

ollegr [7]

Answer:

The correct option is A) Yes, the evidence supports the hypothesis.

Explanation:

In the field of scientific research, a hypothesis can be described as a tentative statement which can either be proved right or wrong based on the results form the experiments we perform.

As the results from the experiment showed that the ball which was thrown from a greater height had a greater speed, hence this means that the evidence from the experiment supported the hypothesis.

Answer:

The skeleton provides a framework for organs and soft tissue attachment.
Blood is formed in the red bone marrow.
Calcium is released and deposited in the bones and blood to maintain (calcium) homeostasis.
Minerals (calcium and phosphorus) are stored in the bones.
When muscles contract/relax, the bones attached to them move.

Explanation:

The skeleton is made up of bones that attaches muscle to the organs. Together, it allows the movement of body for a desired task, e.g. walking, exercising, eating, etc.
Organisms usually have two types of bone marrows, i.e. red and yellow. Red bone marrow is typical for the production of red blood cells (blood) along with platelets and white blood cell formation. In the yellow bone marrow, however, only white blood cells are formed.
Calcium release in the blood is controlled by parathyroid hormone. Its optimal release is important for calcium homeostasis of the living organism both for bone formation and other biochemical processes.
Minerals mainly calcium and phosphorus are stored in the bones. In the animal's body, 99% calcium and 85% of phosphorus are stored in the bones.
The contraction and relaxing of muscle are crucial for the movement of animal's body. For that, two types of muscle fibers namely actin and myosin work together. Actin slides on myosin which is governed by nerve impulses and results in contraction. The relaxing of muscle is an opposite process in which muscle fibers restore to their original positions.
