Compare and contrast open, closed, and isolated systems. be sure to discuss the exchange of energy and exchange of matter, and provides at least one example of each.

Open system - both matter and energy can transfer

closed system - only energy can transfer

isolated system - neither energy nor matter can transfer

Explanation:

1. Open system

An open system is the one in which both energy and matter is exchanged as the substance in this system is free to move. For example - Heating  water in a can without lid. Here both the energy (heat) and matter (water) is allowed to escape.

2. Closed System

In this system,  only energy transfer is possible and exchange of matter is restricted through some external constraint.

For example - when water is heated in a container with a closed lid. Here heat (energy) can escape but water (matter) cannot escape

2. Isolated System

In this system, transfer of both energy and matter is restricted by isolating the system

For example - if water is poured into an insulated container, both heat (energy) and water (matter) are restricted from heating

c) 50% there are four chromosomes. after crossing over, 2 of the four have been changed. that means any gamete has a 2 in 4 chance or 50% chance of receiving the mutated chromosome.

that would be called plucking : )

explanation:

''plucking, also referred to as quarrying, is a glacial phenomenon that is responsible for the erosion and transportation of individual pieces of bedrock, especially large "joint blocks". as a glacier moves down a valley, friction causes the basal ice of the glacier to melt and infiltrate joints (cracks) in the bedrock."
