Human blood groups are governed by three alleles, a, b, and o. a and b are codominant and o is recessive to both. if a woman with type o blood is expecting a child. her husband is typea. both the woman's father and her husband's father had type b blood. what is the probability that the child will have type o blood

Answers

Answer 1

Answer: The probability is half (1/2). I have attached an explanation along with the genetic diagram. Hope this helps and you can ask me any further questions you have about my explanation. :)

Answers

Answer:

1- Temperate rainforest biome

2- Coniferous (boreal) forest biome

3- Desert biome

4- Tundra biome

5- Temperate deciduous forest biome

6- Tropical rainforest biome

Explanation:

The tropical rainforest biome is located near the equatorial region where the amount of sunlight is maximum. As a result of which this area experiences maximum rainfall, that helps in the increasing amount of plants and animal species. This provides all the essential nutrients required by the organisms. Here, in this region, the temperature throughout the year remains high and receives the highest amount of rainfall.

The tundra biome is located in and around the polar region. The temperature in this region remains very cold, supporting a good number of plant and animal species.

The desert biome is located along the 30° latitude in both the hemisphere. The temperature remains relatively very high throughout the year due to the lack of rainfall. The region is very dry. There is significantly less amount of plants in this region.

The movement of fluids between cellular compartments ________. the movement of fluids between cellular compartments ________. is regulated by osmotic and hydrostatic forces requires active transport requires atp for the transport to take place involves filtration

Answers

The movement of fluids between cellular compartments is regulated by osmotic and hydrostatic forces.

Hydrostatic pressure is the force exerted by a fluid against a wall which causes movement of fluid between compartments. This pressure is important for exchanging plasma and nutrients between capillaries and surrounding tissues and also in the nephrons (kidneys) where ensures proper filtering of the blood to form urine.Fluid also moves between compartments along an osmotic gradient (the difference in concentration of solutes on one side of the cell membrane to that on the other side). Water constantly moves into and out of fluid compartments via osmotic gradient.

Which mode of reproduction is matched correctly with its description? 1.transduction-virus transfers genes from one bacteria to another
2.conjugation- involves splitting of one cell and results in two identical cells 3.binary fission--requires direct cell-to-cell contact of bacteria
4.transformation uses a pilus to transmit genetic information between bacteria

Answers

The correct statement is: transduction-virus transfers genes from one bacteria to another. This is a process in which a virus is responsible for transferring DNA from one bacterium to the other. This process does not require physical contact between the cell donating and cell receiving the DNA. Transduction is used by molecular biologists to experiment on host cell genomes when foreign genes are introduced.

Which of these would most likely result in a change to the current classification of an organism?

Answers

Hello. This question is incomplete. The full question is:

"Which of these would most likely result in a change to the current classiﬁcation of an organism? A- Discovering organisms with similar physical traits in the fossil record B- Finding a related organism that was previously considered extinct C- Linking the organism to different ancestors through DNA sequencing D- Observing organisms that occupy the same ecological niche. "

Answer:

C- Linking the organism to different ancestors through DNA sequencing

Explanation:

To formulate the oldest classifications, ecological and physiological characteristics were used, as well as all others that are available for the taxa in question. However, in recent years, classifications based on the similarity between genomes have been attempted, with great advances in some areas, especially when those from other fields of Biology are added to this information. Because of this evolution in the classification technology, a change in the current classification of an organism could occur by linking the organism to different ancestors through DNA sequencing.

The classification of living beings is part of the systematic, science that studies the relationships between organisms, and which includes the collection, preservation and study of specimens, and the analysis of data from various areas of biological research.

Hi There! :)

Which of these would most likely result in a change to the current classification of an organism?

An analysis of the DNA sequence of an organism will most probably result in a change to a current classification of an organism.
>>>DNA analysis is one of the new reasons why organisms/species are being re-evaluated . Basic genetic analysis information can change our ideas of how closely two organisms/species are closely related thus, their classification can change.

The Earth's biodiversity is determined by the variety of all living organisms on Earth. In recent years, ecologists and other scientists have encouraged the preservation of global biodiversity through the protection and management of natural ecosystems.Preserving the biodiversity of the Earth is important because
A. biodiversity increases ecosystem stability for a given type of ecosystem.

B. ecosystems are highly interconnected and the removal of even a few species can cause ecosystem disruption.

C. the diverse organisms of Earth's ecosystems provide services for humans that humans cannot replicate.

D. all of these

Answers

The answer is D because all of them are true. Biodiversity stabilizes an ecosystem, they are highly interconnected, and we can not replicate many forms of life.

Answer:

Answer choice D

An orange roughy fish is a fourth-level consumer that requires almost ten times the amount of food available from the primary producers in the ecosystem. Why isn't more energy available from the primary producers?A. Primary producers are not very efficient and lose most of their energy to the environment.B. There is too much competition from other fourth-level consumers, leaving very little available to the orange roughy.C. Only a fraction of energy is passed through each level, so there is less available to upper-level consumers.D. The energy flow is unbalanced and tends to move toward the lower levels.
