A 2-kg bowling ball sits on top of a building that is 40 meters tall.

Okay, so this is physics. What is the meaning of KE? It's Kinetic Energy. What is the meaning of GPE? It's Gravitational Potential Energy. So how do you calculate either, and what are their significances? Kinetic -> motion, Gravitational potential energy -> energy that can be used to do work due to gravity. So is the bowling ball moving, or is it someplace it can fall from, or both?

Kinetic energy is calculated as 1/2 * mv^2, where m is the mass of the object, and v is the velocity. Potential energy for conservative forces is the product of the force and the distance over which it can do work. Thus in the case of GPE, it is the weight multiplied by the height, as gravity is a conservative force. What is the weight? It's not equal to the mass.

Hopefully these hints will get you thinking.

Consider the parts of a polar ecosystem and a desert ecosystem.
g100num [7]

Answer: Abiotic factor for polar: Ice

Abiotic for desert: Sand

Biotic for polar: Polar bears

Biotic for desert: Cacti

The types of factors are different because there are different set conditions for each ecosystem. A cactus is built for it's hot, dry ecosystem. If it were to move to a polar ecosystem it would not survive there. Same for the polar bear. It's built for polar regions. It has white fur to blend with the white ice to help it blend in and it's adapted to swim to get it's food source.

In a Hardy-Weinberg population with two alleles, A and a, that are in equilibrium, the frequency of allele a is 0.1. What is the
Sati [7]

The correct answer is D) 0,81

When there is Hardy-Weinberg equilibrium like in  this  case of a single locus with two alleles denoted A and a with frequencies f(A) = p and f(a) = q, the expected genotype frequencies under random mating are f(AA) = p² for the AA homozygotes, f(aa) = q² for the aa homozygotes, and f(Aa) = 2pq for the heterozygotes. And we have:

p²+2*p*q+q²= 1       <em>p+q= 1     p=1-q</em>

q= 0.1     p= 1-0.1= 0.9

p²=0.9²= 0.81

Patrick wants to trace the progress of development of a frog embryo. Which technique will he use for this?
Oduvanchick [21]
It should be C! (: Fate mapping because it is used do dermine tissue linage!
While Differentiation is used when one cell type changes from one cell to another.
When it comes to the process an undifferentiated cell is already programmed to become a specific cell type by following a specified path towards cell differentiation.
I hope all is well, and you pass! (: Good luck, rockstar! If you need any further information, let me know. (:
