Answer:

water contracts and ice sinks

Answer:

For #2, water expands when it freezes, therefore it floats!

Explanation:

Water first condenses when it freezes until it reaches about 4 degrees Celsius, where it then slowly expands by about 9%. It also floats! You can observe this yourself by placing ice into a glass full of water.

Ice floats because it is less dense than the water below.

Marco has experienced extreme fatigue (tiredness) lately. He eats three balanced meals each day and exercises 2-3 times per week on his Peloton bike. He gets 7-8 hours of sleep each night, but just can’t seem to stay awake during the day. Which organelle is most likely causing Marco’s problems?

Answers

Given the symptoms shown by Marcos, we can infer that the organelle that may be causing his problems is the mitochondria.

The mitochondria are one of the most famous and important organelle within a cell. Found in most eukaryotic cells, they are the organelle responsible for most of the energy production of a cell, and throughout the cells of the body, they become responsible for the energy production of the organism. This is the origin of its famous "Powerhouse of the cell" title. Mitochondria produce energy in the form of ATP.

ATP is a molecular compound necessary for most of the reactions that take place in a cell. It is so common as a requirement for any cellular activity that ATP is known as the "molecular currency". Marcos is said to be experiencing chronic fatigue, which is a symptom of mitochondrial disease. When the mitochondria of an organism's cells are not functioning as they should be, the cells do not have the energy needed to perform basic functions.

In reaction to this, the body sends signals to the brain to go to sleep, which minimizes energy consumption by slowing down the metabolic processes which require ATP and thus gives the body time to produce more energy. For these reasons, we can conclude that the fatigue and problems Marcos is experiencing are due to mitochondrial disease.

How are the amounts of carbon dioxide and oxygen inhaled by lungs different from the amounts exhaled? How do cellular respiration and the law of conservation of mass relate to this?
I NEED HELP!!

Answers

Answer:

1. Gas exchange takes place by diffusion in the alveoli within the lungs. As a result the composition of inhaled and exhaled air is different.

...

Inhaled and exhaled air.

Gas % in inhaled air % in exhaled air

Oxygen 21 16

Carbon dioxide 0.04 4

Nitrogen 79 79

NB These figures are approximate.  

2. The amount of carbon-dioxide atoms released by respiration are exactly equal to the atoms of these materials contained in the oxygen and carbon converted. In this way respiration has conserved the mass or material and in this way followed the law of conservation of mass.

Explanation:

What is Cellular Respiration?

Cellular Respiration is the process in which the cells of living things break down the organic compound glucose with oxygen to produce carbon dioxide and water. The overall chemical equation for cellular respiration is:

C6H12O6 + 6O2 → 6CO2 + 6H2O + energy (stored in ATP)

Cellular respiration takes place in the cells of all organisms. It occurs in autotrophs such as plants as well as heterotrophs such as animals.

Q: How is cellular respiration related to breathing?

A: Breathing consists of inhaling and exhaling, and its purpose is to move gases into and out of the body. Oxygen needed for cellular respiration is brought into the body with each inhalation. Carbon dioxide and water vapor produced by cellular respiration are released from the body with each exhalation.

Energy Changes in Cellular Respiration

The reactions of cellular respiration are catabolic reactions. In catabolic reactions, bonds are broken in larger molecules and energy is released. In cellular respiration, bonds are broken in glucose, and this releases the chemical energy that was stored in the glucose bonds. Some of this energy is converted to heat. The rest of the energy is used to form many small molecules of a compound called adenosine triphosphate, or ATP. ATP molecules contain just the right amount of stored chemical energy to power biochemical reactions inside cells.

The DNA has deoxyribose sugar while RNA has ribose sugar, that's what gives the doble stranded and single stranded form respectively.
