Answer:
1. gerund phrase
2. the second choice (i think)
Explanation:
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 think it’s C, but it could possibly be B
Answer:style
Explanation:
Fashion cycle – a period of time or life span during which the fashion exists, moving through the five stages from introduction through obsolescence
The scientists need to measure for forces are magnitude and direction.
<h3>What is Force?</h3>
The force is defined as the external effort applied in the form of push or pull to cause the acceleration of a body.
Mathematically it is expressed as the product of mass and acceleration of an object.
therefore standard expression for the force as per Newton's second law is given as,
F = ma
Here,
m is the mass of the body.
a is the magnitude of the acceleration of the body.
Also, the force is a vector quantity that has significance for its magnitude as well as the direction.
So scientific analysis regarding the force needs its magnitude along with the direction of application.
Thus,The scientists need to measure for forces are magnitude and direction.
