Human blood type is determined by co-dominant alleles. An allele is one of several different forms of genetic information that is present in our DNA at a specific location on a specific chromosome. There are three different alleles for human blood type, known as IA, IB, and i. For simplicity, we can call these alleles A (for IA), B (for IB), and O (for i).
Each of us has two ABO blood type alleles, because we each inherit one blood type allele from our biological mother and one from our biological father. A description of the pair of alleles in our DNA is called the genotype. Since there are three different alleles, there are a total of six different genotypes at the human ABO genetic locus. The different possible genotypes are AA, AO, BB, BO, AB, and OO.
How are blood types related to the six genotypes?
A blood test is used to determine whether the A and/or B characteristics are present in a blood sample. It is not possible to determine the exact genotype from a blood test result of either type A or type B. If someone has blood type A, they must have at least one copy of the A allele, but they could have two copies. Their genotype is either AA or AO. Similarly, someone who is blood type B could have a genotype of either BB or BO.
A blood test of either type AB or type O is more informative. Someone with blood type AB must have both the A and B alleles. The genotype must be AB. Someone with blood type O has neither the A nor the B allele. The genotype must be OO.
How are ABO alleles inherited by our children?
Each biological parent donates one of their two ABO alleles to their child. A mother who is blood type O can only pass an O allele to her son or daughter. A father who is blood type AB could pass either an A or a B allele to his son or daughter. This couple could have children of either blood type A (O from mother and A from father) or blood type B (O from mother and B from father).
Since there are 4 different maternal blood types and 4 different paternal blood types possible, there are 16 differnt combinations to consider when predicting the blood type of children. In the tables below, all 16 possible combinations are shown. If you know the blood type of the mother and father, the possible blood types for their children can be found.
What about the Rh factor? Can a father of blood type A+ have a child who is blood type A-?
The Rh factor genetic information is also inherited from our parents, but it is inherited independently of the ABO blood type alleles. There are 2 different alleles for the Rh factor known as Rh+ and Rh-. Someone who is "Rh positive" or "Rh+" has at least one Rh+ allele, but could have two. Their genotype could be either Rh+/Rh+ or Rh+/Rh-. Someone who Rh- has a genotype of Rh-/Rh-.
Just like the ABO alleles, each biological parent donates one of their two Rh alleles to their child. A mother who is Rh- can only pass an Rh- allele to her son or daughter. A father who is Rh+ could pass either an Rh+ or Rh- allele to his son or daughter. This couple could have Rh+ children (Rh- from mother and Rh+ from father) or Rh- children (Rh- from mother and Rh- from father).

how much energy moves up from one trophic level to the next in the energy pyramid
Answer: Only about 10% of energy is transferred from one trophic level to the next. Most of the rest of the energy is lost through heat (energy expended, metabolic process, respiration) as it transfers along each level. The reason for this energy loss is found in the second law of thermodynamics which states: that as energy is transferred energy is lost.

What are some ways that living things can be classified? What characteristics should we look at when putting living things into groups?
The classification of living things includes 7 levels: kingdom, phylum, classes, order, families, genus, and species. Characteristics such as appearance, reproduction, mobility, and functionality are just a few ways in which living organisms are grouped together. These specialized groups are collectively called the classification of living things.

Describe the fossils found in the top layers of the Grand Canyon.
Answer:
Sedimentary fossils/rocks
Explanation:
The sedimentary rocks exposed throughout the canyon are rich with marine fossils such as crinoids, brachiopods, and sponges with several layers containing terrestrial fossils such as leaf and dragonfly wing impressions, and footprints of scorpions, centipedes, and reptiles. Sedimentary rocks are formed from pre-existing rocks or pieces of once-living organisms. They form from deposits that accumulate on the Earth's surface. Sedimentary rocks often have distinctive layering or bedding.

Earth's mantle is made of liquid molten material. The inner part of the mantle is hotter than the outer part. Therefore, currents carry molten material up to Earth's surface. Then, they cool off so much that they sink back down inot the warmer area. What type of heat transfer is this? [ Select ]
Answer:
Convection currents are what cause the warmer molten material to rise up, and when it cools, to sink back down.

Question: how the distance from a plate boundary affects the earthquake
Answer:
The strength of shaking from an earthquake diminishes with increasing distance from the earthquake's source.
Explanation:
So the if the strength of the shaking at the surface from an earthquake that occurs at 500km deep is considerably less than if the same earthquake had occurred at 20 km depth.
Answer:
lol , ok so the strength and the shacking of the earthquake diminishes with increasing distance from the earthquake's source, so the strength of shaking at the surface from an earthquake that occurs at 500km deep is considerably less than if the same earthquake had occurred at 20 km depth.

Organisms are divided into different kingdoms based on differences in their characteristics. Two major characteristics that scientists
use to determine which kingdom an organism belongs to are
ability to make food and ability to swim.
OA
OB ability to swim and number of cells.
OC.
ability to fly and size of organism.
OD
ability to make food and number of cells.
Answer:
A. ability to make food and ability to swim
Explanation:
Living organisms have been grouped into an hierarchical system of classification that begins with the kingdom, which is the most inclusive taxon. Organisms were placed into kingdoms based on two major criteria namely; their nutrition and mobility.
Their nutrition depends on their ability to make food by themselves (autotrophic) or not (heterotrophic) while their mobility depends on their possession of structures for locomotion.

Which of the statements are characteristics of a good hypothesis? -is developed from data that cannot be replicated -relies heavily on cutting edge technology -is created from careful research and logical reasoning -is based only on a presentation by an expert in the field -is able to be tested using validated techniques
Answer:
is created from careful research and logical reasoning
is able to be tested using validated techniques
Explanation:
A hypothesis can be defined as a prediction/expectation that is made in order to understand a phenomenon from the real world. This prediction must be testable and measurable by using the scientific method. In science, a good hypothesis clearly defines the relationships between two or more variables (independent variables and dependent variables). Moreover, a good hypothesis must also be written in simple and precise language, which means that its statements must be understandable (and verifiable) for any person and/or researcher working in the field.
