Chromosomes are packaged by histone proteins into a condensed structure called chromatin. ... The two identical chromosomes that result from DNA replication are referred to as sister chromatids. Sister chromatids are held together by proteins at a region of the chromosome called the centromere.
Answer:
h = 20 m
Explanation:
Given that,
Force to lift a firefighter's equipment, F = 270 N
Work done, W = 5400 J
We need to find the height climbed by the firefighter. We know that,
Work done, W = Fd
So,

So, the firefighter climb from a height of 20 m.
It's an interesting fact that scientists don't fully understand how it works. But it seems to be to do with molten metal circulating in the core. Given that it's just liquid metal sloshing around, it seems understandable that it won't always circulate perfectly - imagine the cloud bands in Jupiter's atmosphere - they are reasonably stable but change from time to time. When the liquid changes its speed or direction, however slowly it does so, the resulting magnetic field will move or switch direction.

As scientists try to build better mathematical models of how the core works, they should be able to learn more about the magnetic field it produces. Hope this helps</span>
The right answer for the question that is being asked and shown above is that: "A. Compressions and rarefactions make up longitudinal waves, which can only travel in matter." The statement that best describes longitudinal waves is that c<span>ompressions and rarefactions make up longitudinal waves, which can only travel in matter.</span>
Answer:
Explanation:
Given that,
Small piston Hydraulic piston has an area
A1 = 0.01m²
If the force applied is 250N is applied to the small piston at an area of 0.05 m²
Then,
F2 = 250 N and A2 = 0.05m²
Then, applying pascal principle,
Pressure at small area = pressure are bigger area
P1 = P2
F1 / A1 = F2 / A2
F1 / 0.01 = 250 / 0.05
F1 / 0.01 = 5000
Cross multiply
F1 = 5000 × 0.01
F1 = 50 N
