What organ does the gaseous exchange in

Answers

Answer 1

Answer:

Answer:

Respiratory System

Explanation:

Gas Exchange Between Alveolar Spaces and Capillaries. The function of the respiratory system is to exchange two gases: oxygen and carbon dioxide. The exchange takes place in the millions of alveoli in the lungs and the capillaries that envelop them

The structure labeled x most likely represents

Answers

The propositions are :
(1) an antibody
(2) an enzyme
(3) a receptor molecule
(4) a hormone

The right answer is an enzyme because it has catalytic activity. It transforms a substrate which is the starch to product(s) which are dextran and maltose

It is not an antibody because it does not have catalytic activity as a major role.
It is not a receptor molecule, because they cannot transforms molecules and forms products
It is not a hormone because it does not have a catalytic activity

Final answer:

In chemistry, a structure labeled 'X' can refer to different things depending on the context. 'X' might refer to a specific atom within a Lewis structure or a point of maximum deformation (the amplitude) on a wave. It could also refer to specific atomic arrangements such as a molecule with an octahedral electron-group geometry.

Explanation:

The question is asking about a structure labeled 'X', which could refer to various concepts within a chemistry context. However, given the information provided, it's likely that 'X' refers to either a specific molecule within a Lewis structure, or it could indicate a point on a waveform (in the context of quantum mechanics) that represents maximum deformation (the amplitude of the wave).

For example, if using the formal charge criteria, 'X' could signify a particular atomic structure with a desirable formal charge of zero. However, without a detailed diagram or further context, these are educated estimations.

Beyond atomic structures or wave patterns, 'X' might also signal specific molecule arrangements like an atom with four single bonds, a double bond, and a lone pair resulting in an octahedral electron-group geometry and a square pyramidal molecular structure. One such instance is the XeOF4 molecule.

What happens when an atom gets excited

Answers

Answer:

When an electron absorbs energy, it jumps to a higher orbital. An electron in an excited state can release energy and 'fall' to a lower state. When it does, the electron releases a photon of electromagnetic energy.

Which of the following statements is true about biomes? Geographic location is not one of the three main ways biomes are classified. Geographic location has nothing to do with classification of biomes. Geographic location is random; there can be many biomes in one region of the world. Geographic location is generally quite important as it affects the climate and what types of organisms live in a biome.
