Answer:
1. Increase
2. Decrease
Explanation:
During inspiration, diaphragm contracts and lowers down. There is a simultaneous contraction of external intercostal muscles and movement of rib-cage upward and outward. All these events lead to an increase in the volume of the thoracic cavity. Increase in volume of the thoracic cavity results in expansion of lungs and lowering down the air pressure within alveoli of lungs.
You would generally not be able to recover fossils from volcanic or plutonic rock, so looking around in an area on active volcanic islands would yield nothing.
You always want to look in the layers of sedimentary rock for fossils. The Grand Canyon would be a great place to see these layers as well as a shallow ocean because you may find the remains of prehistoric shark teeth or bones protruding through the surface of the sand.
The answer is Active volcanic islands.
If this is a question in which you can choose more than one answer it may be smart to also choose a shallow ocean as well. This is because it is difficult to get the tools and materials necessary down in the water and would be difficult to get deep enough underneath sand to start digging into actual fossil bearing rock.
So in that case, the answer would then be both Active volcanic islands and A shallow ocean.
Neutral carbon-12 (or any carbon atom) has 6 electrons with a total negative charge of 6e- orbiting a nucleus with a total positive charge of 6e+, so that the total net charge is zero. The nucleus is made up of 6 protons, each with a positive charge of e+, and 6 neutrons, each with zero charge.

Visual traits, like cell shape and size, are the most important criteria for determining similarity between species. thus option C is correct.

What is the significance of numerical taxonomy?</h3>
In biological systematics, numerical taxonomy is a categorization scheme that deals with the numerical grouping of taxonomic units according to their character states. Instead of employing a subjective assessment of their qualities, it seeks to construct a taxonomy using numerical procedures like cluster analysis.
The data produced can effectively be used in the design of better keys and classification systems because numerical methods are more sensitive in delimiting taxa. Numerous biological ideas that have long been accepted have been reexamined in the context of numerical taxonomy.
