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.

During which stage of the cell cycle does cell division occur? o interphase o quiescence o cell growth 0 mitosis
Mitosis is the process by which body cells divide. is the process by which body cells divide. The cells in multicellular organisms undergo mitosis repeatedly. The cells produced by mitosis are used for growth. They are also used to repair body tissues and replace worn-out cells. The image shows the input and output of mitosis. Notice that two cells are produced when one cell undergoes mitosis and cell division. Both cells produced are identical to the starting cell.
-Therefore, mitosis is the correct answer.
Differences in the moons pull on different parts of the earth cause blank
The Moon's gravity pulls more on the planet than the water on the opposite side. These two water bulges on opposite sides of the Earth aligned with the Moon are the high tides. Since ocean water is pulled higher in the areas of the two high tides, there is less water in between the two high tides.
In many polygynous songbird species, such as wrens or red winged blackbirds, a single male holds a territory and mates with several females on that territory. In monogamous species, such as cardinals and blue jays, mated pairs typically hold a territory and males mate with only one female. In comparably sized populations, do you expect drift to have a stronger effect in polygynous species or monogamous species? Explain your choice.
Genetic drift is a phenomenon which changes the allele frequency of a population due to a natural catastrophic which is random. The phenomenon occurs in the small population and chances of change in the allele frequency are very less in the large-sized population.
The size of the population is affected by the mating also and the monogamous species have more genetic diversity compared to the polygamous species but the polygamous mate to maximize the chances of breeding. These lead to the change in the genetic drift and both the polygamous and monogamous species will be affected by the drift process.
Which characteristic allows carbon to form chains and rings eith other carbon atoms
Because each carbon is identical, they all have four valence electrons, so they can easily bond with other carbon atoms to form long chains or rings
Question 22 (5 points)The major difference between B cells and T cells is that T cells do not produce antibodies. B cells do not produce antibodies. B cells always circulate in the blood stream. T cells always circulate in the blood stream.
B cells always circulate in the blood stream

Which of the following are synapomorphies of mammals? a. Hair b. Vertebral column c. Five digits d. Mammary glands e. Endothermy f. Placenta
Answer: A) Hair and D) Mammary glands
Synapomorphies of mammals are hair and mammary gland as, mammals are the distinct from the other tetra-pods having hair,mammary gland and three bone ear. The three unique trait of mammals included three bones ear malleus,stapes and incus, presence of the hair and mammary gland for the production of milk.
