In a mono hybrid cross of heterozygous pea plant with round (R) yellow (Y) seeds there will be genotype ratio of 9 _____ 3,____
andreev551 [17]

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.

s344n2d4d5 [400]

The given question is not complete. The complete question is:

A company in San Francisco uses petroleum products to make plastics. Arrange the sentences in the correct order to show how the company could be contributing to climate change.

Put in order:

1.Burning fuel releases greenhouse gas

2.higher air temperature causes ocean water to evaporate more rapidly

3.Greenhouse gases trap solar radiation and warm up the atmosphere

4.The company burns fuels to make plastic

5.The amount of water vapor in the air rises, which further increases the air temperature

Answer:

The development of the source of energy that takes place millions of years to form by the action of temperature and pressure under the heap of sediments are known as fossil fuels. The organic matter of dead plants and animals are the raw materials needed for fossil fuel development, however, these are the non-renewable source of energy as it never is replenished once vanished.  

These fossil fuels are used in enormous amounts by the industries, which liberate gases like sulfur dioxide, carbon dioxide, nitrous oxide, and other deleterious components upon burning. These gases are the major source of global warming that even contributes to climate change.  

Based on the given question, the following are the steps in the correct order that contributes to climate change:  

4. The burning of fuel is done by the company to produce plastic.  

1. This burning of fuel discharges greenhouse gases in the atmosphere.  

3. The trapping of solar radiation takes place by greenhouse gases, which eventually increases the temperature of the atmosphere.  

2. This increase in the temperature of the air makes the water bodies like oceans evaporate more briskly.  

5. This further results in the increase in the concentration of water vapor in the air that further elevates the temperature of the air.
