Explanation:
In humans, three alleles affect blood type. The A and B alleles are codominant, and the O allele is recessive. An AB blood type father has children with an A blood type mother (genotype AO). What are the chances that their children will have AB type blood? Choose 1 answer: Choose 1 answer: (Choice A) A 25\%25%25, percent (Choice B) B 50\%50%50, percent (Choice C) C 75\%75%75, percent (Choice D) D 100\%100%100, percent
Answer:
The correct answer is - A. 25%.
Explanation:
In humans, the blood group system is known as the ABO system where blood groups A and B are codominant and O blood group is recessive. The genotype of the A blood group could be AA or AO similarly for the B blood group genotype would be BB or BO, for the O blood group OO whereas for the AB blood group both A and B alleles should be present together.
Cross: AB blood type father with an A blood type mother (genotype AO)
Gametes: A, B and A, O
Punnett square:
A B
A AA AB
O AO BO
Here, there are 25% chances of AB blood group offspring 50% for the A blood group (AA and AO) and 25% B blood group (BO).
What is the ultimate role of ecological succession in an environment
Answer:
The stable, end stage of ecological succession in which the plants and animals of a community use resources efficiently and balance is maintained by disturbances such as fire. The ultimate goal of ecological succession. After a natural disaster and continues until a climax community is reached.
Explanation:
The ultimate role of ecological succession in an environment is to reach the equilibrium in an ecosystem.
What is Ecological Succession?This event involve in the steady and gradual change in a species of a given area with respect to the changing environment is called as ecological succession.
The changes are inevitable process where all biotic components of the ecosystem keep up with the changes in our environment.
This process ultimately reach equilibrium in the ecosystem and the community that achieves this referred as a climax community, where some species increase in number and others decrease.
The communities that undergo changes sequentially in an area is called sere, so it is also called as seral stage or seral community.
Evolution has taken place simultaneously with that of ecological succession, so all the communities we observe are the result of ecological succession.

Alcon blue butterflies spend the first part of their lives as caterpillars that live with Myrmica ants. When a caterpillar lives with the ants, it pretends to be a Queen ant by making noises that make it sound like the Queen ant. Queen ants receive more food and better protection than any other ants in the nest. When the caterpillar mimics a Queen ant, the ants feed and protect the caterpillar instead of other ants in the nest. Which word best describes the relationship between the caterpillar and ants
Answer:
The correct answer is - parasitic.
Explanation:
The Maculinea Alcon butterfly has a unique relationship with species of Myrmica ants. The butterfly's caterpillars picked up by passing Myrmica ants, and take to their nests where this caterpillar makes sounds like the queen ants, and to this sound, all ants protect and feed this caterpillar instead of other ants.
Normally there is a mutualistic relationship between ants and caterpillars but in the case of The Maculinea Alcon caterpillar and Myrmica ants, there is a parasitic relationship.

1. Rank the test tubes in order of greatest amount of digestion to

have exhibited that that level of digestion.
2. How could the experiment be modified to further test human
digestion actions? What variables would you change? What would
you keep the same?
3. In which test tube was the activity most like that of a real human
stomach? Explain.
Answer:
Los alimentos son nuestro combustible y sus nutrientes proporcionan a las células del cuerpo la energía y las sustancias que necesitan para funcionar. Pero, antes de que los alimentos puedan hacer eso, los debemos digerir, descomponiéndolos en trozos pequeños para que nuestros cuerpos los puedan absorber y aprovechar.
El primer paso del proceso digestivo tiene lugar antes de que ni tan siquiera probemos la comida. Con solo oler una tarta de manzana casera o pensar en lo delicioso que va a saber un tomate maduro, empezamos a salivar, y el proceso digestivo se inicia preparándonos para ese primer bocado.
Casi todos los animales tienen un sistema digestivo en forma de tubo, donde los alimentos:
entran por la boca
pasan por un largo tubo
salen del cuerpo en forma de heces (caca) a través del ano
A lo largo del camino, se descomponen en moléculas diminutas para que el cuerpo pueda absorber los nutrientes que necesita:
Las proteínas se deben descomponer en aminoácidos.
Los almidones se descomponen en azúcares simples.
Las grasas se descomponen en ácidos grasos y glicerol.
Los residuos que el cuerpo no puede aprovechar son los que salen del cuerpo en forma de heces.

How could the aquifer around the Los Angeles are in California be susceptible to an impact by a Tragedy of the Commons?
Answer:
Due to over-pumping of water.
Explanation:
The aquifer around the Los Angeles are in California could be susceptible to an impact by a Tragedy of the Commons because the people used more water than the aquifer receives. The excess use of water from the aquifer through the well causes depletion of water which results in the shortage of water to fulfill the needs of existing population so it is wise to use water efficiently and used lower or equal water the aquifer receives in order to maintain level of aquifer.
