Answer: 340m
Explanation:
Given that:
Streets are constructed from 10 m pieces;
A lamppost is placed at both ends and at every 10 m along its length ;
A lamppost is also placed at every notice board along its length :
Given that:
Einstein Street has 42 lamppost and 7 notice boards :
So,
7 lamppost for 7 notice boards :
Lamppost left = 42 - 7 = 35 lamppost
2 lamppost placed at both ends :
Lamppost left = 35 - 2 = 33 lamppost
Hence, the remaining is placed at 10 m along its length:
Hence, length of Einstein street :
33 lamppost each placed 10m from the starting lamppost = (33 * 10) = 330m
Distance between 33rd lamppost and the ending lamppost = 10m
Hence, total length = (330 + 10) = 340 m
Answer:
drugs capable of influencing perception, mood, cognition, or behavior
Answer:
b) the effects of local evolution or migration on an exosystem
Explanation:
a) false; symbiosis is the relationship between two species with either a mutual benefit to both creatures, one benefiting and the other remaining neutral, or one being negatively affected while the other benefits. There is no relationship between the two groups of blackcaps to a is false.
b) true; the effects of local evolution or migration on an ecosystem. Local evolution has not occured yet but migration has. The effect that scientists believe may happen to the ecosystem because of the migration is the creation of a new species, which would definitely effect an ecosystem
c) false; biotic factors are the living parts of an environment, such as plants, animals, and insects. The difference in the two groups of blackcaps isn't what biotic factors they use but when their mating season is. Biotic factors have no effect whatsover.
d) false; there are no given alterations in the ecosystem. Migration patterns do not just change because of something as small as a shift in bug population. Migration habits are largely genetic, such as is the case of monarch butterflys migrating from north to south and back across the continent. If a group of blackcaps are migrating somewhere different, it has been ocurring for a while, so it isn't fault of the ecosystem that suddenly made blackcaps switch migration course.
I like Olivia too. Not really sure why this is a brainly question tho lol.
