It's a system of chronological dating and geologists use it to describe the timing and relationships of events in Earth's history
Vinvika [58]2 years ago

Answer: The geologic time scale, GTS, is a system of chronological dating that relates geological stratigraphy to time. It is used to describe the timing of events that have occurred in the history of the Earth.

Geologists use GTS because the time durations of events between significant observable changes are much longer than those that occur in normal human life.

At what temperature does all molecular motion stop?
Over [174]

Answer:

Absolute Zero

Explanation:

It is based on molecular motion, with the temperature of 0K, also known as absolute zero, being the point where all molecular motion ceases. The freezing point of water on the Kelvin scale is 273.15K, while the boiling point is 373.15K

It wouldn't be 0 degrees C or 0 degrees F because the temp of the molecular motion stop in Celsius is -273.15 degrees and in Fahrenheit it would be -459.67 degrees.

I hope this helps :)

When you eat salmon for dinner, your digestive system will break down that food
zimovet [89]

Answer:   c. Amino Acids

Explanation:

Food is chemically and mechanically broken down into smaller particles like building blocks, the smallest of these are a basic unit called monomers. In the <em>stomach</em>, the enzyme pepsin breaks proteins, like those found in salmon, into smaller peptides by splitting the peptide bonds holding the proteins together. The <em>duodenum</em> processes these newly-formed peptide chains or polypeptides, into smaller ones, through the enzyme action of elastase, trypsin and chymotrypsin; these are produced in the pancreas. Peptidases convert these fragments into amino acid monomers for absorption into the bloodstream via the small intestines.

1. Water has many unique properties that contribute to making Earth habitable. Describe all four of these unique properties of w
marysya [2.9K]

The properties are:-

1. Water is polar. Water molecules are polar, with partial positive charges on the hydrogens, a partial negative charge on the oxygen, and a bent overall structure. This is because oxygen is more electronegative, meaning that it is better than hydrogen at attracting electrons.

2. Water is an excellent solvent. Water has the unique ability to dissolve many polar and ionic substances. This is important to all living things because, as water travels through the water cycle, it takes many valuable nutrients along with it!

3. Water has high heat capacity. It takes a lot of energy to raise the temperature of a certain amount of water by a degree, so water helps with regulating temperature in the environment. For example, this property allows the temperature of water in a pond to stay relatively constant from day to night, regardless of the changing atmospheric temperature.

4. Water has high heat of vaporization. Humans (and other animals that sweat) use water’s high heat of vaporization to cool off. Water is converted from its liquid form to steam when the heat of vaporization is reached. Since sweat is made mostly of water, the evaporating water absorbs excess body heat, which is released into the atmosphere. This is known as evaporative cooling.

Which of the following statements is true? Which of the following statements is true? Cardiac muscle is found in the heart and l
jenyasd209 [6]

Answer:

Striated muscle cells are long and cylindrical with many nuclei

Explanation:

There are three types of muscles cells present in man

1. Cardiac Muscle: Found only in the heart. They are involuntary and intrinsically controlled, striated, branched, and single nucleated

2. Smooth Muscle: typically non-striated, uni-nucleated, and involuntary or reflexive. This muscle type is slow twitch and often rhythmic in contraction

3. Skeletal muscle: They are voluntary, striated, not branched, and multinucleated.
