Answer:
Carbohydrates are organic molecules ONLY composed of carbon, hydrogen, and oxygen molecules. So, their structure would be just covalent bonds between the three elements, and most likely non-polar. They give out a lot of energy, and carbohydrates are also known as sugars. Most foods have them.

HEYYYYYYYYYY PLEASE HELP!!!!!
Answer:
Velocity
Explanation:
Given the change in positive (direction) over time we are given the velocity formula.
V = Change in direction/Change in time
Since we are given a direction we can rule out speed as well as direction in itself. We can also rule out acceleration because that is the change in Velocity divided by change in time.

Which would conserve more energy if all humans ate only vegetables or ate only meat
Answer:
There would be more conservation of energy if human beings it only meat.
Explanation:
this is because meat consists of a significant portion of the fat. The amount of of energy that is liberated per molecule of fat is almost twice the amount of energy that is liberated by carbohydrate or protein. As a result of this the total energy consumption will be more if human being consumes only fat. however it takes more time to digest fat as compared to that of carbohydrate and protein.

What is the connection between the liquid state of water and hydrogen bonding?
Answer:
In the liquid state, the hydrogen bonds of water can break and reform as the molecules flow from one place to another. When water is cooled, the molecules begin to slow down. Eventually, when water is frozen to ice, the hydrogen bonds become permanent and form a very specific network.

How would the equilibrium change if the ocean became more acidic?
Answer: more H2CO3 is made
Explanation:
Acidic water of the ocean creates instability in the ocean ecosystem.
What happens when ocean become acidic?If the acidity of ocean increases the corals can't build skeletons and the shellfish also can't build the shells which they need for protection.
Corals are particularly important because they provide homes for many other sea creatures so we can conclude that acidic water of the ocean creates instability in the ocean ecosystem.

Warm water rises because it is ............ than cool water.
a) warmer
b) cooler
c) more dense
d) less dense
**Answer and I will give you brainiliest**
Answer:
I'm pretty sure the answer is D.) Less Dense
Explanation:
Answer:
d) less dense
Explanation:
When fluids (liquids and gases) are heated, they expand and therefore become less dense. Any object or substance that is less dense than a fluid will float in that fluid, so hot water rises (floats) in colder water.

According to the model of the human respiratory system, how do structures in the
respiratory system interact to protect the lungs? How might a sinus infection affect the
rest of the respiratory system?
Answer: The circulatory and respiratory systems work together to circulate blood and oxygen throughout the body. Air moves in and out of the lungs through the trachea, bronchi, and bronchioles. Blood moves in and out of the lungs through the pulmonary arteries and veins that connect to the heart.
Explanation:
There are Cilia that protect the airways of the lungs from invaders and pathogens by trapping them. Sinus is present in the nose which blocks the airways while it swells.
What is the respiratory system?The respiratory system is the system that is responsible for getting oxygen into the body and removing carbon dioxide from the body.
Together, the respiratory and circulatory systems move blood and oxygen throughout the body. The trachea, bronchi, and bronchioles are the pathways by which air enters and exits the lungs. The pulmonary arteries and veins, which attach to the heart, carry blood into and out of the lungs.
Thus, there are cilia that, by trapping invaders and diseases, defend the lungs' airways. The nose has a sinus, which obstructs the airways when it grows.

Under what circumstances would molecular motion stop?
Answer:
All molecular motion stops at 0 degrees Kelvin or -273.15 degrees Celsius.
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
