Answer:
Inspiration (breathing in)
The diaphragm contracts and moves downwards. The intercostal muscles contract and move the ribs upwards and outwards. This increases the size of the chest and decreases the air pressure inside it which sucks air into the lungs. During normal breathing, the major inspiratory muscles produce rib cage expansion and a downward movement of the diaphragm. These movements cause the pressure around and in the lung to become negative (relative to atmospheric pressure).
Explanation:
Liqiud water will change from a liquid to a solid at 0°C when heat energy has been removed.
Think about it liquid water expands when it turns into ice.
Answer:
Nematodes are referred to as "pseudocoelomates" since their coelom is not entirely lined with mesoderm ally cell - derived in most forms, and they are triploblastic.
<h2>What is a nematode?</h2>
Any unsegmented worm of the phylum Nematoda, having an elongated, cylindrical body; a roundworm
<h2>What are characteristics of the pseudocoelomate phylum?</h2>
<em>-bilateral symmetry, unsegmented, triploblastic</em>
<em>-body cavity a pseudocoel</em>
<em>-size: some microscopic, others a few meters in length</em>
<em>-body veriform</em>
<em>-complete gut (2 cavities)</em>
The structure of the body wall of pseudocoelomates explained:
<em>-muscles are longitudinal (no circular) beneath the hypodermis</em>
<em>-non-living cuticle secreted by the hypodermis</em>
<em>-composed of many layers of collagen</em>
<em>-useful for protection and containing high pressure of hydrostatic skeleton</em>
<em>-muscles contract and push against</em> fluid which causes movement
Answer:
This question is incomplete
Explanation:
This question is incomplete because of the absence of the diagram illustrating the growth chamber. However, since insects also produce/exhale carbon dioxide (CO₂) as a waste product, the level of CO₂ in the growth chamber will increase since insects will serve as an additional source for the production of CO₂.
This model shows how carbon is been cycled though the earth's systems. The CO₂ released/exhaled by animals is been inhaled by plants and used for the production of food substance like glucose (through the process of photosynthesis). Animals eat these plants and then release carbon from these food sources as CO₂ which is taken up from the environment again by plants.
Answer:
The lighter moths would be more suitable and the darker moths would eventually die out since they have no camouflage, thus an influx of lighter moths will emerge.
