In a mono hybrid cross of heterozygous pea plant with round (R) yellow (Y) seeds there will be genotype ratio of 9 _ 3,_ 3,_ and 1_ PLEASE PLEASE HELP IM KIND OF CONFUSED

Genotype ratio refers to the probability of each type of thing (in this case, round/yellow seeds) occurring based on the Punnett square. If you were to write out how many of each specific hybrid occurred in the square, you'd get:

1 RRYY

2 RRYy

2 RrYY

4 RrYy

1 RRyy

1 rrYY

1 rryy

What does this tell us? In this case, the only thing that matters is the capital letter (since that's the dominant trait and will determine whether the seed is/isn't round/yellow).

Looking at each one, you see some of them are the same - for example, RRYY and RRYy both end up as round and yellow. RrYy is too, as is RrYY.

So, you end up with 9 round and yellow; 3 round and not yellow; 3 not round and yellow; 1 not round and not yellow.

an adaptation is a change or process by which an organism takes to be better suited for its environment. for example; migration is a behavioral adaptation, this is needed because birds are not built to last extremely cold climates. there are different adaptations because there are different species needing to adjust to different things, bears don't migrate; they hibernate.

weathering - colorado river carves land in arizona to form the grand canyon. cracks form in a sandstone wall surrounding a house. a marble statue near the science museum is changing color due to rainfall

erosion - after a rainstorm, soil and rock piees litter the roadways. the sand dunes in the sahara desert are changing shape.

here's your answer.
