Answer:An arthropod (/ˈɑːrθrəpɒd/, from Ancient Greek ἄρθρον (arthron) 'joint', and πούς (pous) 'foot' (gen. ποδός)) is an invertebrate animal having an exoskeleton, a segmented body, and paired jointed appendages. Arthropods form the phylum Euarthropoda, which includes insects, arachnids, myriapods, and crustaceans.
Explanation:
B) 10
C) 100
D) 200
Answer: Option (C) is the correct answer.
Explanation:
It is known that pH is a measure of acidity or alkalinity of a solution. When pH is less than 7 then the solution is acidic in nature and when the pH is more than 7 then the solution is basic in nature.
Pure water is neutral in nature and it has a pH of 7, that is, it is neither acidic nor basic in nature.
Whereas coffee is acidic in nature as it has pH of 4 to 5 which is very acidic as compared to pure water if we go from 5 to 7 on a pH scale.
So, we can conclude that the pH of coffee is 100 times greater than the pH of pure water.
It would be 100 times greater if you are going from a pH of 5 to 7
Answer:Harmful or beneficial mutations do influence an organism's survival. This is where natural selection comes into play. ... This is how organisms evolve and adapt to changing environmental conditions over time.
Explanation:
Answer: The environment affects natural selection. Speices need to adapt to changes in environmet. The weaker organisms which fail to adapt to environment perish while the stronger ones who adapt to the environment survive. This is how environment affects natural selection.

B) accessing food
C) obtaining oxygen
D) avoiding predators
Answer:
The answer is C
Explanation:
Because in order for it to breath well it needs to move its gills
White tip reef sharks pump water across their gills to obtain oxygen.
White tip reef sharks spend most of the day lying on the ocean floor. They pump water across their gills while remaining still, as the movement of water across their gills is necessary for obtaining oxygen. Gills in fish, including sharks, absorb oxygen from the water as it passes over them. Sharks have well-developed sense organs that aid them in locating prey, including a keen sense of smell and the ability to detect electromagnetic fields.
Electroreceptors called ampullae of Lorenzini allow sharks to detect the electromagnetic fields that are produced by all living things, including their prey. The lateral line is used to detect movement and vibration in the surrounding water, and is often considered to be functionally similar to the sense of 'hearing' in terrestrial vertebrates.
