Answer:
Through chemical reactions.
Explanation:
You tell if an unknown powder is salt, sugar, flour or baking soda by doing tests to see how the powder would react. For an example, baking soda in vinegar would cause it to fizzle, while flour would just make the vinegar murky and cloudy. With salt and sugar, you can test if it dissolves and if it does it is sugar. If not, it is salt.
Answer:
The phenotypic ratio will be 3:1
Explanation:
As per this question there are two phenotypes for seed color, yellow and green. Both the parents are true breeding that means they are homozygous for this trait. Also, all the F1 plants have yellow seed color which clearly indicates that yellow seed color is a dominant trait while green is recessive trait.
The cross of true breeding plants as mentioned above is depicted as under:
Parents YY x yy
/ \ / \
F1 generation Yy Yy Yy Yy
So, as per the law of dominance because of the presence of Y allele, all these progeny will be yellow in color.
Next, when these F1 plants will be crossed, the result will be as under:
F1 generation Yy x Yy
/ \ / \
F2 generation YY Yy Yy yy
The genotypic ratio of F2 generation is 1:2:1
The phenotypic ratio of F2 generation is 3:1
It simply means that in F2 generation, 3 progeny which have allelic combination YY & Yy will be yellow colored while 1 progeny which has allelic combination yy will have green color.
Answer:
HUMAN BEINGS AND OTHER ANIMALS EXCEPT PLANTS ARE HETEROTROPHS
Explanation:
HETEROTROPHS ARE ORGANISMS THAT CAN NOT MAKE THEIR OWN FOOD
E.G Human beings and other animals
<em>water is important because it gives space to the substances to get in it also it makes the substances wet and dissolve the gases in it ,to transport them from one place to another... </em>
