One parent has type A blood and the other has type B. What are their genotypes if they produced children whose blood types were all type AB?
Answers
Answer:
iAiA and iBiB
Explanation:
Blood type in humans is controlled by a gene with three alleles namely: iA, iB, and i. Alleles iA and iB are dominant over allele 'i' but codominant. The following are the allelic combinations of the genotype and the resulting blood types:
iAiA or iAi - type A
iBiB or iBi - type B
iAiB - type AB
ii - type O
According to this question, one parent has type A blood and the other has type B. If all the offsprings of these parents have blood type AB, this means that the parents must have a genotype of iAiA and iBiB respectively.
What are antibiotics and when can they not be used
Answers
Answer:
An antibiotic is a type of antimicrobial substance active against bacteria. It is the most important type of antibacterial agent for fighting bacterial infections, and antibiotic medications are widely used in the treatment and prevention of such infections. They may either kill or inhibit the growth of bacteria. Antibiotics DO NOT work on viruses, such as those that cause: Colds and runny noses, even if the mucus is thick, yellow, or green. Most sore throats (except strep throat) Flu.
Answer:
Antibiotics are medicines that help stop infections caused by bacteria. They do this by killing the bacteria or by keeping them from copying themselves or reproducing. Antibiotics do not work on viruses, such as those that cause colds, flu, bronchitis, or runny noses, even if the mucus is thick, yellow, or green. Antibiotics are only needed for treating certain infections caused by bacteria, but even some bacterial infections get better without antibiotics.

Answer:
There is (from closest to the surface of the Earth) ...
Explanation:
Troposphere: the lowest region of the atmosphere, extending from the earth's surface to a height of about 3.7–6.2 miles (6–10 km), which is the lower boundary of the stratosphere.
Stratosphere: the layer of the earth's atmosphere above the troposphere, extending to about 32 miles (50 km) above the earth's surface (the lower boundary of the mesosphere).
Mesosphere: the region of the earth's atmosphere above the stratosphere and below the thermosphere, between about 30 and 50 miles (50 and 80 km) in altitude.
Thermosphere: the region of the atmosphere above the mesosphere and below the height at which the atmosphere ceases to have the properties of a continuous medium. The thermosphere is characterized throughout by an increase in temperature with height.
Exosphere: the outermost region of a planet's atmosphere.

Answer:
The correct answer is B. ) Carbon Dioxide
Explanation:
Took the test and got it right! Hope this helps! Have a good day!
The gas that is released into the atmosphere as glaciers melt is known as carbon dioxide. Thus, the correct option for this question is B.
What is an Atmosphere?An atmosphere may be characterized as a type of envelope that consists of a mixture of numerous gases and surround the planet of the earth and other celestial bodies. It plays a series of functions in order to facilitate the survival of living entities.
As glaciers melt, carbon trapped within the soils is significantly liberated into the atmosphere as carbon dioxide and methane. These gases are released into the atmosphere and definitely cause numerous adverse effects like more warming, which then thaws more the frozen soil.
Therefore, the gas that is released into the atmosphere as glaciers melt is known as carbon dioxide. Thus, the correct option for this question is B.

Due to a single mutation some individuals start breeding in the fall and not in the spring, like the other individuals of this species. As a result, these two populations (spring and fall breeders) living together evolve into two separate species. This is an example of: Group of answer choices
Answers
Answer:
Reproductive barrier ⇒ isolation mechanism ⇒ seasonal or temporal isolation.
Explanation:
Reproductive barriers are isolation mechanisms that prevent mating between two or more species. The prezygotic mechanism avoids fertilization between individuals of different species, and the postzygotic mechanism avoids the zygote to develop and reach the adult stage.
Among the prezygotic mechanisms, we might find behavioral isolation, seasonal or temporal isolation, sexual isolation, gamete incompatibility.
Seasonal or temporal isolation occurs when individuals of different species occupy the same area, have the same reproductive behavior, and their gametes are compatible, but they do not get to mate because their reproductive seasons differ.
In the exposed example, after the speciation process, both bird species living together are not capable of mating because one of the species mates in the spring and the other one breeds in fall.
The reproductive barrier is the process in which two species are not able to reproduce due to the variation in the species.
Reproductive barrier isolation has two types:-
Mechanism seasonalTemporal isolation.
Seasonal or temporal isolation happens when individuals of different species live in the same area, have the same reproductive behavior, and their gametes are compatible,
The birds given in the question are not able to reproduce due to seasonal variation. In the speciation process, both bird species living together are not capable of mating because one of the species mates in the spring and the other one breeds in fall.

. Traits cannot be good or bad, their effect on the success of a creature depends on the environment and circumstances.
. A mutation in an individual is evolution.
. The process of evolution is random, but the selection of genes/traits is not.
. An organism that is more complex is more evolved.

Which of these could cause the amount of carbon dioxide in the atmosphere to decrease?
Answers
Answer:
An increase in the number of producers.
Explanation:
Producers/plants absorb carbon dioxide during photosynthesis and give off oxygen.Therefore to decrease the carbon dioxide in the air,we would have to plant more trees.
Have a nice day.
The percentage of carbon dioxide in the atmosphere should be 0.04% an increase in this amount can adversely affect the environment. Its amount can be decreased by increasing producers.
What is carbon cycle?Carbon cycle is the process of circulating carbon atoms from atmosphere to Earth and then again to atmosphere.
Carbon dioxide is increased in atmosphere by increasing respiration, increasing amount of decomposers, use of fossil fuels.
The way to decrease the concentration of carbon dioxide in atmosphere is by increasing number of producers.
Producers makes their food by absorbing carbon dioxide and release oxygen as a byproduct, hence decreasing the concentration of carbon dioxide.
Thus, the correct answer is D.
