DaniilM [7]

Let us solve first the phenotype of this problem.

Starchy grain = AA (dominant)

Sugary Corn = aa (recessive)

AA x aa = AaAa ; AaAa

<span>     A    A</span>

<span>a  Aa   Aa</span>

<span>a  Aa   Aa</span>

The result of the cross is that the progeny will become heterozygous.

<span>If there is 58 progeny sugary, there will also be 58 starchy. It is 50%.</span>

A substance is very sour and has a ph of 4. what color would you expect it to turn a piece of litmus paper
Anika [276]
If a substance is very sour and has a ph of 4, then you would expect the litmus paper to turn into the shade of red. A substance that is sour and has a pH level that is below 7 would indicate that the substance is an acid or has acidic properties. For an acidic solution, the litmus would be red in color. If a blue litmus paper is used, then it would turn into red while if a red litmus paper is used, then it would remain as red. There is also a general type of litmus paper where the color change range from violet to red. A litmus is widely used in distinguishing acid and bases. It can be used in liquid solutions and in gas mixtures. <span />

pickupchik [31]

Carbon film fossil is the type of fossil that preserves delicate details of an organism after pressure squeezes out liquids and gases.

Carbon film fossil is a type of fossil that is mainly composed of carbon and can preserve delicate details of organism’s (animal and plants) parts. The formation of carbon film fossil starts when a dead organism is buried under sediments. After some time, the organism will begin to decay in a process known as carbonization.
