Answer:

decreases; rises; out of

Explanation:

When the diaphragm contracts, the size of the thoracic cavity <u>decreases</u>, the pressure inside the thoracic cavity<u> increases</u>, and air flows <u>out of</u> the lungs.

<em>During the process of breathing out, the diaphragm and the intercostal muscles relax and this leads to a </em><em>decrease</em><em> in the volume of the thoracic cavity. Since there is an inverse relationship between volume and pressure, the decrease in the volume of the thoracic cavity leads to an </em><em>increase</em><em> in its pressure. Consequently, the lung contracts and </em><em>air is forced to leave it.</em>

<h3>Why did Mendel use the pea plant?</h3>

Mendel used the pea plant to study inheritance patterns in living organisms for a variety of reasons. These include:

  • The pea plant is easy to nurse to maturity
  • It produces many seeds
  • It has many contrasting physical attributes
  • It has a short life span.

What’s one example of a real-world problem which you might use knowledge from biological anthropology to help solve?
LekaFEV [45]

Answer:

Biological anthropology shows that cultural contexts are useful to explain human evolution.

Explanation:

Biological anthropology is a research area focused on the study of biological and behavioral determinants associated with human evolution. Biological anthropology enables us to trace the evolutionary origins of hominids and primates in general. Moreover, this discipline also sheds light on how different environments act on the mechanism of natural selection and thus shape human behavior. However, biological anthropology should not be considered to be part of social Darwinism used to apply Darwin's ideas to social policies.

Which information could a student determine from only the chemical formula of a protein? A) The color of the protein B) The numb
satela [25.4K]

Answer: D) The number of atoms of each element of the protein

Explanation: A chemical formula of a protein or any compound is the representation of the number of atoms of each element present in that protein or compound using chemical symbols and numbers. A symbol of an element consists of either the initial letter or the initial letter with one small letter from its name. Examples: symbol of carbon atom is C and the symbol of calcium atom is Ca. In writing chemical formula of a compound, the number of atoms of an element present in the compound is usually written as a subscript to the symbol of that element. Example: The chemical formula of glucose is C6H12O6, this means that there are six carbon atoms, twelve hydrogen atoms and six oxygen atoms in one molecule of glucose.
