Answer:
(three) crossing over, mutations caused during crossing over, and independent assortment.
Explanation:
Because of recombination and independent assortment in meiosis, each gamete contains a different set of DNA. This produces a unique combination of genes in the resulting zygote. Recombination or crossing over occurs during prophase I.
Answer:
Hello your question is incomplete attached below is the complete question
answer :
23) The concentration of water in the beaker = 75% i.e. : 100% - 25%
24) The Bag is Hypotonic to the Beaker ;
25) The Beaker is Hypertonic to the Bag
26) The direction in which the water will move is from the Bag to the Beaker
27) the Bag will shrink
28) The movement of salt and water will continue until the concentration of the beaker and the bag is equal
Explanation:
23) The concentration of water in the beaker = 75% i.e. : 100% - 25%
24) The Bag is Hypotonic to the Beaker ; this is because the extracellular fluid ( Beaker ) has a lower concentration than the fluid inside the cell ( bag ),
25) The Beaker is Hypertonic to the Bag ; This is because the extracellular fluid( Beaker ) has a higher concentration than the cell’s cytoplasm ( bag ),
26) The direction in which the water will move is from the Bag to the Beaker
27) The condition that will occur if too much water moves out is that the Bag will shrink
28) The movement of salt and water will continue until the concentration of the beaker and the bag is equal
These are some ways how scientists and engineers develop, use and refine models.
1. Imagine. They have to know what exactly trying to model. They have to imagine and brainstorm what are the things to be considered.
2. Reason. Next, they need to answer the questions brought from their brainstorming. They need to be able to reason out.
3. Calculate and Predict. Once they know it, that's the time they can start modelling and calculate - and predict.
