how does the rock cycle support the explanation that "matter is never created or destroyed?"
Answer:
The chemical elements that make up minerals and rocks are not destroyed. This fact illustrates the principle of conservation of matter. The changes that take place in the rock cycle never destroy or create matter. The elements are just redistributed in other forms.

Healthy human lungs look pink and spongy from the outside. The left lung is a little smaller than the right lung to make room for the heart. The lungs and heart are both protected by the rib cage. In the lungs, each main bronchus branches off into many smaller bronchi. The bronchi become smaller and smaller, and the smallest bronchi are called bronchioles. There are about 30,000 bronchioles in each lung, each about the same thickness as a strand of hair. The inhaled air eventually ends up in tiny air sacs called alveoli at the end of each bronchiole. There are about 300 million alveoli in each lung. They are covered with capillaries, tiny blood vessels that are only one cell thick. Oxygen travels from the alveoli through the capillaries to the bloodstream, heart and other cells.
Which of these best represents the progression of bronchi, bronchioles and alveoli in the lungs?
A
tree trunks that become smaller branches and twigs
B
a tight flower bud that has opened into a full bloom
C
whole apples that are sliced into separate wedges
D
a bridge that crosses two rivers

Explanation:
Construct an explanation that describes how matter moves through your body during cellular respiration.
Cellular Respiration: The process by which organisms break down glucose into a form that the cell can use as energy.
Through the process of cellular respiration, the energy in food is changed into energy that can be used by the body's cells. Initially ... Cellular respiration can be described as the reverse or opposite of photosynthesis.
Cellular respiration is a set of chemical reactions cells use to change the food we eat, the water we drink, and oxygen from the air we breathe into forms the cell can use as energy. In the process, matter is transformed from one type to another; that is, atoms from these materials are arranged into new forms.
In this exercise we have to use our knowledge of biology to describe how cellular respiration occurs, so we can say that:
We can say that the respiratory process uses energy and oxygen to have the ability to move through the body.
How does cellular respiration take place?Cellular respiration is a process by which organisms obtain energy to perform the most diverse activities. Cellular respiration occurs in mitochondria, in the presence of oxygen, and is divided into three steps: glycolysis, the citric acid cycle (or Krebs cycle) and oxidative phosphorylation.
What are the steps of cellular respiration?Cellular respiration is a process that involves 3 steps:
Glycolysis, which takes place in the cytosol. Citric acid cycle, which occurs in the mitochondrial matrix. Oxidative phosphorylation, which occurs in the inner mitochondrial membrane.Through the process of cellular respiration, the energy in food is changed into energy that can be used by the body's cells.

What happens when an organism genome (genetic code) is incorrectly copied or changed?
Answer:
When there is a mistake in the copying of the genetic message that is permanent, a mutation has occurred. Two of the bases in DNA (Cytosine and Thymine) are the most vulnerable, and when this happens, they may pair with each other or themselves and the message is changed.

What is the problem with using common names in classification?
A general phobia with unfamiliar latinized scientific nomenclature has proliferated the use of common or trivial names. These names, however, can vary with geographic region, language, or individual preference often and thus, can lead to misidentification or a delay in the proper identification of a toxic plant.
Answer:
The only problem of using common names is that we cannot deduce the features of a particular organism just by looking at its name.
Explanation:
The only problem of utilizing basic names is that we can't find the highlights of a specific organic entity just by seeing its name.

In your own words what is the function of the cell membrane?
Answer:
cell membrane, provides protection for a cell. It also provides a fixed environment inside the cell, and that membrane has several different functions. One is to transport nutrients into the cell and also to transport toxic substances out of the cell.
Explanation:
Hope this helps!
Answer:
The cell membrane provides a wall of protection around the cell, and also provides a way to regulate the transportation of materials going in an out of the cell.

Respiration begins when air enters the mouth and nose. As air goes down the trachea, or windpipe, tiny hairs called cilia gently wave to keep dirt and mucus out. At the bottom of the trachea are two tubes called bronchi. One bronchus goes into the left lung, and the other goes into the right lung. When you inhale, the diaphragm muscle between the lungs and abdomen contracts, making room for the lungs to expand.
Which of these best describes how the lungs and diaphragm affect each other?
A
As the lungs expand, the diaphragm expands.
B
As the lungs expand, the diaphragm contracts.
C
As the lungs contract, the diaphragm contracts.
D
The lungs and diaphragm have no relationship.
what is the main function of the skin
Answer:
The skin has three main functions: Protection; Thermoregulation; Sensation.
Explanation:
protection from injury, infection and water loss, regulation of body temperature, elimination of wastes, gathering information and production of vitamin D.Provides a protective barrier against mechanical, thermal and physical injury and hazardous substances. Prevents loss of moisture. Reduces harmful effects of UV radiation. Acts as a sensory organ (touch, detects temperature).Absorption of UV rays, thermoregulation and protection for underlying tissues are all functions of skin.
