Why are some incomplete fossils able to be pieced together? Full fossils of large animals can be found together. Hard tissue, like bone, never breaks or chips. Fossils require salt water to be preserved fully. Impressions from the skin can be preserved.
Answers
Answer:
Explanation:
The fossil record is considered to be incomplete because fossilization is a very rare phenomenon. Most organisms decompose quickly after their death, and their remains dispersed. In order for fossilization to occur, the remains have to be covered by sediments and stay undisturbed for thousands of years.

Identify two characteristics shared among transverse waves, longitudinal waves, and surface waves.
Answers
Answer: For transverse waves, the waves move in perpendicular direction to the source of vibration.
For longitudinal waves, the waves move in parallel direction to the source of vibration .
They are similar within the sense that energy is transferred within the kind of waves.
Explanation:
The shared characteristics between traverse, longitudinal and surface waves include :
Traverse, longitudinal and surface waves are all mechanical waves They only transport energy without transporting matter.Mechanical waves are simply waves which requires a material medium to propagate. They include longitudinal, surface and traverse waves.
Also, all three waves transfer energy through a medium without the transfer of materials or matter in the medium.
Therefore, all three waves are mechanical waves and do not transfer matter.

Answer:
The answer to this question is......C
Two or more than two atoms with different physical or chemical properties can not combine together to form an element. Therefore, Sr is the element which is most reactive. The correct option is option C.
What is element?Element generally consist of atoms or we can atoms combine to form element. Atoms of an element is always same, means all the properties of all atoms of one type of element is same.
On going down the group of periodic table, size increases due to increase in number of shells, easiness to eject one electron increases. Group 2 elements are the most reactive as it has only 2 electrons to loose. Sr is the element which is most reactive among all the given options.

Explanation:
What we eat, and how we move our bodies, effects our blood. How does that end up affecting our other organs in the body
Answers
Answer:
The digestive system converts the foods we eat into their simplest forms, like glucose (sugars), amino acids (that make up protein) or fatty acids (that make up fats). The broken-down food is then absorbed into the bloodstream from the small intestine and the nutrients are carried to each cell in the body.
Answer:
The digestive system is made up of the gastrointestinal tract—also called the GI tract or digestive tract—and the liver, pancreas, and gallbladder. The GI tract is a series of hollow organs joined in a long, twisting tube from the mouth to the anus. The hollow organs that make up the GI tract are the mouth, esophagus, stomach, small intestine, large intestine, and anus. The liver, pancreas, and gallbladder are the solid organs of the digestive system.
The small intestine has three parts. The first part is called the duodenum. The jejunum is in the middle and the ileum is at the end. The large intestine includes the appendix, cecum, colon, and rectum. The appendix is a finger-shaped pouch attached to the cecum. The cecum is the first part of the large intestine. The colon is next. The rectum is the end of the large intestine.

1. Using D10W and a vial of NaCl 4 mEq/mL, how many mL of NaCl are needed to prepare 250 mL of a
D10/NS solution?
a. 4.8mL
b. 9.6ml
c. 19.6mL
d. 154mL
Answers
To prepare 250 mL of a D10/NS solution using D10W and a vial of NaCl 4 mEq/mL, you would need 9.6 mL of NaCl. Normal saline (NS) contains 154 mEq/L of sodium chloride (NaCl). To prepare 250 mL of NS, you would need 250 mL * (154 mEq/L) = 38500 mEq of NaCl. Since the vial of NaCl contains 4 mEq/mL, you would need 38500 mEq / (4 mEq/mL) = 9625 mL = 9.6 mL of NaCl. So the correct answer is b. 9.6ml.
