Scientist can communicate their findings by putting them on a journal and publish them
According to lecture, the level of emission reductions pledged by individual countries at the paris climate agreements are sufficient to prevent dramatic climate change according to many scientists. <u>The statement is False.</u>
The issue is that many scientists believe the existing pledged emission reductions won't stop serious climate change.Leading the way in global efforts to combat climate change has been the EU. It played a key role in negotiating the Paris Agreement and continues to lead the world.
The EU presented its updated and improved NDC in December 2020, along with information to promote the ICTU (clearness, transparency, and understanding) of the NDC and a target to cut emissions by at least 55% from 1990 levels by 2030.
By working together, the EU and its Member States are committed to a legally-binding goal of a net domestic reduction of greenhouse gas emissions of at least 55% from 1990 to 2030.

Answer:
option b
Explanation:
paramecium posseses cilia
Answer:
A native-species
Explanation:
A native-species is one that normally lives and thrives in a particular ecosystem. They are any species that developed within the surrounding habitat.
They are usually found in an ecosystem because of natural processes like evolution or natural selection. They are known to occur naturally within a given habitat as opposed to species that are introduced.
Given data:
● Angular velocity of the turntable ω = 33 rev/min
Therefore,
ω = 33 rev/min
ω = 33rev/min × 2π rad/rev × 1 min/60 sec = 3.45 rad/s
● The distance of the watermelon seed from the axis of rotation r = 7.8 cm = 0.078 m
● μs = the coefficient of static friction
Section a:
The seed is undergoes circular motion and it is been effected by centripetal acceleration.
ac = rω^2
ac = 0.078 × 3.45^2
ac = 0.9284 m/s^2
Therefore,
the centripetal acceleration of the seed is 9.274 m/s^2
Section b:
If the seed is observed not to slip at the course of the circular motion, then the supplied frictional force given by the seed and surface of turntable would at least be equivalent to the centripetal force working on the seed.
Centripetal Force = Frictional Force
mrω^2 = μsmg
μs = rω^2 /g
μs = 0.078 × 3.45^2
------------
9.81
μs = 0.09464
Thus,
the coefficient of static friction is 0.09464.
