lions [1.4K]

Answer:

C.) crystalline solids

Explanation:

The solid materials may be crystalline or amorphous. The concept of crystal structure is related to the organization of atoms in a geometrical form. Crystalline structures are present in various materials, where atoms distributed within their structure form a network called the crystalline lattice. Therefore, crystalline structures have salts, metals and most minerals. Crystalline structures are formed by unit cells that are their basic unit, as they constitute the smallest set of associated atoms found in a crystalline structure.

The molecules of the crystalline structures can have two types of bonds, the directional ones, which include the covalent and dipole dipole and the non-directional ones where the metallic, ionic, van der Walls bonds. When formed by ionic compounds, these crystalline structures can result in crystalline solids.

What type of intelligence refers to a person's ability to reason speedily and abstractly?
Anna11 [10]

Answer:

a. Fluid intelligence

Explanation:

Cattell-Horn's theory of fluid and crystallized intelligence suggests that intelligence is composed of a series of different skills that interact and work together to produce general individual intelligence.

<u> Fluid intelligence</u> implies being able to think and reason abstractly and solve problems. This ability is considered independent of learning, experience and education. It is basically configured by primary skills such as induction, deduction, relationships and figurative classifications, breadth of associative memory and intellectual speed, among others. It reaches its maximum splendor in the early twenties and tends to decrease in parallel to the aging and deterioration of neurons. This ability can be measured from tests that measure the biological potential of the individual to learn or acquire knowledge.

Tomtit [17]

The right answer is to measure the amount of released carbon dioxide.

The carbon dioxide exhaled by the lungs can reflect the energy consumed by the body since it comes from the degradation of glucose which is the main energy substrate. And this is a better indicator of energy consumption than measuring heart rate because it can be inflected by several factors.


A is false because glucose is not found in the urine, except in the case of diabetes mellitus.

C is false because the consumption of calories does not mean that we will directly use it.

D is wrong because perspiration is independent of energy consumption, this is a way to cool the body after exercise.
