Answer: C. Oxygen delivery to muscle is increased when more carbon dioxide is produced by the muscle.
Explanation:
When someone is doing an exercise, for example, his heart rate increases. This increases the rate at which oxygen is carried from the blood to the muscles and carbon dioxide is moved from the muscles to the lungs, where it will be breathed out.
1. Brackish water is most commonly found in rivers. (It is where the Fresh water meets the sea water)
2. The answer would have to be true
3. Air temperature does not affect tides.
<u>Coquina</u> is the sedimentary rock is made up of pieces of shells.
Two types of sedimentary rock: Clastic and chemical sedimentary rocks
Explanation:
Coquina is the sedimentary rock formed by fragments or pieces of shells of marine animals like mollusks, brachiopods, trilobites and certain invertebrates.
The shells of marine animals are fragmented due to abrasion and mechanical degradation and sorting by the wave action and chemicals present in the sea water and gets transported which then sediments to form rock structures called coquina. The shells mostly contain calcium carbonate.
Chalk is the sedimentary rock formed b the fossil shells fragmented from foraminifers. This is a more powdery type of limestone.
Depending upon the type of sedimentation, sedimentary rocks are of three types:
Clastic – Made from sedimentation of clastic (pieces from broken rocks) through the processes of mechanical weathering and lithification (cementing and compacting). sandstone, conglomerate
Chemical – Made from evaporation of water and precipitation of materials which were previously dissolved in a solution. Example: Rock salt, dolomite
Organic – Repeated accumulation and sedimentation of organic matter or remains from plant and animal sources like bones (calcium deposits). Example: coal.
"D: A new gene, which codes for the protein that can repair defective genes, is introduced."
Explanation: <span>Gene therapy is an experimental technique that uses genes to treat or prevent disease. In the future, this technique may allow doctors to treat a disorder by inserting a gene into a patient’s cells instead of using drugs or surgery.</span>
