I think that this is an example of excretion of metabolic waste. Metabolic waste are substances that have been left after metabolism that the body cannot make use of and have to removed from the body. Body excretes are in form of water solute except for carbon dioxide which is in form of gas together with water vapor from the lungs.

Day 1: 4 km Day 2: 10 km Day 3: 12 km Day 4: 12 km Day 5: 18 km Day 6: 24 km
yKpoI14uk [10]

Answer:

In order to find average speed during each interval, we need to divide the distance during those intervals with the period of time. So, for the first interval (day 0 to day 2) hawksbill started from 0 and reached 10 kilometers by the end of the second day. That means that it crossed 10 kilometers in 2 days, so the average speed is 10/2 which is 5 km/day. Similarly, we can calculate speed for other intervals:

• day 2 - day 3: it went from 10 to 12 km in one day, which means it crossed 2 km in one day, so the average speed is 2/1 = 2 km/day

• day 3 - day 4: at the end of the third day it reached 12 km and at the end of the day 4 it remained at 12 km. That means the hawksbill wasn't moving in that interval so the speed was 0

• day 4 - day 5: it went from 12 km to 18 km, which means it crossed 18-12=6 km in one day, so the average speed is 6/1=6 km/day

• day 5 - day 6: it went from 18 to 24 km, which means it crossed 24-18=6 km in one day, so the speed was 6/1=6 km/day

So, to summarize, during the first interval turtle was moving with average speed of 5 km/day, then 2 km/day, in the third interval it wasn't moving and in the last two intervals, it moved in average speed of 6 km/day.

Earlobe type is an inherited trait and can be described as attached or detached. Earlobe type is a ____________ that is coded by
GenaCL600 [577]
Earlobe type is PHENOTYPE, that is coded by a person's GENOTYPE. 
The genotype refers to a team of genes in a person that is responsible for the expression of a particular trait. For instance, a genotype is responsible for the height of a person, whether the person is short or tall depends on the particular genotype that controls the height trait. Phenotype refers to the physical characteristics or physical manifestations of a particular trait. For instance, tallness is a phenotype, it is a physical expression of the genotype that controls height. In the same way, earlobe type is a phenotype that is determined by a person's genotype.
