Answer:
This question is incomplete
Explanation:
This question is incomplete because the time taken by each individual was not provided but a guide can be used to determine the most appropriate unit to represent the winning time. The most appropriate unit will be determined in the manner below.
<u>If the times are equivalent and the time taken (to finish 30 hot dogs) across all contestants are less than 60 secs, the most appropriate unit will be seconds. But if the time taken across all contestants are more than 60 secs (or 1 minute) but less than 3600 secs (or 60 minutes), the most appropriate unit will be minutes. However, if the time taken across all contestants are more than 3600 secs (or 60 minutes or 1 hour), the most appropriate unit will be hours.</u>
The correct answer is:
Delta, when sediments are deposited where a river flows into an ocean it forms a delta.
Explanation:
A river delta is a landform that appears from the deposition of sediment transported by a river as the flow issues its mouth and begins slower-moving or stagnant water. This occurs where a river starts an ocean, sea, estuary, lake, reservoir, or (more rarely) different river that cannot carry away the satisfied sediment.
Answer:
a) is present in honhuman primates but not humans, because humans lost this feature.
Explanation:
The opposable big toe is a trait that helps to primates to climb trees easily. Humans' ancestors started to walk in two legs, this created a needing for better stability, so a fixed toe became to evolve to allow our bipedal locomotion.
Therefore, options b and c are wrong. Option d is wrong too because it implies that the group "primates" is newer than "humans", and in fact, "humans" is part of the group "primates", so this is not the correct answer.
Answer: Hemoglobin
Explanation: The Kastle-Meyer test relies on the iron in hemoglobin, which is the iron-containing portion of a red blood cell, to promote the oxidation of phenolphthalin to phenolphthalein. Phenolphthalin is colorless, but in the presence of blood and hydrogen peroxide, it changes to phenolphthalein, which makes the solution pink.
Answer:
Right here
Explanation:
Mutations are important because if an animal dose not evolve then the species will die off.
