Answer
The correct answer would be B) 50 %.
In humans, the blood group is determined by three alleles 
and 
.
are co-dominant whereas is recessive to other two.
Thus, the genotype of a person with blood group O would be 
.
The genotype of a person with blood group B would be either 
(homozygous condition) or 
(heterozygous condition).
The crosses are shown in the image below.
There is only one condition in which the person can have offspring with blood group O that is, when the other parent is .
In this condition, the probability of an offspring to have blood group O is 50%.
In other condition, the probability of an offspring to have blood O is 0%.
H2O is a substance that that is classified as a compound. It is the chemical formula of water. A compound is two or more elements that have been chemically combined. In this question, water has two elements which are hydrogen (H) and oxygen (O). Two hydrogen atoms combine with one oxygen atom to form a compound. The answer will thus be B.
answer
B)heterotrophs
-autorophs
Encyclopedic entry. An autotroph is an organism that can produce its own food using light, water, carbon dioxide, or other chemicals.
-heterotrophs
An organism that cannot manufacture its own food and instead obtains its food and energy by taking in organic substances, usually plant or animal matter. All animals, protozoans, fungi, and most bacteria are heterotrophs. Compare autotroph.
-producers
In ecology, we define producers as organisms that are able to make their own food through photosynthesis or chemosynthesis. ... An organism that cannot make its own food cannot be a producer in ecology by definition.
I know that they need air to live
A very acidic level is 0 on the pH level. and a very basic pH level is 14. 7 on the pH scale is neutral. Anything lower than 7 is acidic, and anything higher than 7 is basic.
