If Tom Harris had type AB blood and Mary had type O, could the type O child they brought home be their child? * No, the baby would have to have inherited a gene for O from both parents and Tom has only a gene for A or B. Yes, both parents had the recessive hidden gene for O blood in their genotype which they passed on to the baby. No; the baby would have to have Type AB blood that it inherited from the father since A and B are dominate to O. Yes; the baby inherited type O blood from the mother Mary Harris which is dominant to the genes for both A and B.
The study of blood is called hematology. The component of blood is RBC, WBC, platelets, and plasma.
The correct answer to the question is option B.
What is a blood group?
A blood type is a classification of blood, based on the presence and absence of antibodies and inherited antigenic substances on the surface of red blood cells.
These antigens may be proteins, carbohydrates, glycoproteins, or glycolipids, depending on the blood group system.
The genes A and B are dominant over O therefore the O blood group can not be seen in offspring.
Hence, the correct answer to the question is option B is Yes, both parents had the recessive hidden gene for O blood in their genotype which they passed on to the baby. No; the baby would have to have Type AB blood that it inherited from the father since A and B are dominant to O.

4 At what trophic level do decomposers obtain their energy?
Answer. They are the “last trophic level” in some hierarchies because they feed on everything (National Geographic). However, according to the strict trophic level definition they would be primary consumers.
The expected ratio of phenotypes among the progeny of a test cross is 1:1:1:1. Out of 200 total resulting progeny, 48 occur in one of the four phenotypic classes. Given this information, which of the following must also be true?1) Since 48 is so close to the expected value, there is no need to calculate chi square before drawing a conclusion about the ratio. 2) At least one additional cell must also contain a count of 48. 3) The value of observed - expected for this cell = -2. 4) The progeny of this cross do not conform to a 1:1:1:1ratio.
Answer: The progeny of this cross do not conform to a 1:1:1:1 ratio
Explanation: This is because out of the 200 total resulting progeny, we must have 50 in each phenotype class to conform with the 1:1:1:1 which is not so as we have 48 in one of the phenotypic class already. Therefore, it did not conform to the ratio.
The value of observed - expected for this cell = -2
"With a total of 200, the expected number in each cell when the predicted ratio is 1:1:1:1 = 50. The observed number is 48." - Mastering Genetics

A few organisms have evolved to use mostly asexual reproduction. what must be true about these?
I cannot find the statements, I will explain the asexual reproduction so you can answer the question by your own:
Asexual reproduction is as simple a cell multiplication as a photocopying machine reproduced in one or more copies an original document. In all cases, we obtain a clone of cells all having the same hereditary information.
The great advantage of asexual reproduction is its speed. It produces a new organism that is genetically identical to the parent you do not have to look for a partner Energy can be deployed to produce potentially large numbers of offspringOffspring are usually adapted to their environment by the success of their parent Helps to quickly and effectively colonize a parent-friendly habitat, thanks to a large number of descendants he can breed in a short timeThe offspring are often already multicellular and more viable.
The inconveniences are: Does not cause a genetic diversity of organisms of the same species. The species does not adapt at all or very slowly depending on the changing circumstances. There is only one parent to care for the offspring. The parent disappears sometimes because his body is no more (binary fission, fragmentation). An asexual species may be suddenly destroyed by a disaster that affects all genetically identical organisms of this species.
