Answer: When using fossils approximate age by comparing it to similar rocks and fossils of known ages, is called relative dating.
Using that method we can determine the age of rock layers. That’s our way of dating them.
Hope this helps! ^^
Answer:
Functions of vascular bundle: Transportation of water and minerals from roots to other plant parts and leaves. Transportation of food from leaves to all other plant parts.
Explanation:

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.

Probably. Ecosystems are connected. While scientists do break the world
down to study it in smaller pieces because we can't comprehend the
ecosystem of the whole world at one time, the whole world is one big
ecosystem. Some parts of it are more directly connected to others, and
some parts are less directly connected. If something catastrophic
happened in one ecosystem, it would affect other ecosystems. But also
remember that the bigger the network, the less any one species affects
it. Because<span> there
are so many species in the world, the world is a HUGE ecosystem. The
affect would be somewhat absorbed by the vastness of the ecosystem.
However, if the extinction of one species (such as fish) has a large
impact on one ecosystem, it's impact on surrounding ecosystems might be
noticed. When you look at the world as a whole, it's not the extinction
of any one species that is very, very dangerous but the extinction of
many species. If enough species (like the fish) died in "separate"
ecosystems, eventually the ecosystem of the whole would be affected.</span>
