A father is heterozygous (AO) for his type A blood and a mother is heterozygous for her type B(BO) blood. What percentage of their offspring would you expect to have a child with O type blood?
Answer:
2 : 2 BO : OO
Explanation:
Children either have blood group B or O thus the probability of a child being either blood group B or O is 50%.

The major goal of the Social Gospel movement in the late 19th and early 20th century was to: Promote the spread of Protestantism in United States territories Promote the spread of Protestantism in United States territories Draw the attention of Protestant churches to the plight of the urban poor Draw the attention of Protestant churches to the plight of the urban poor Encourage support for Charles Darwin's theory of biological evolution Encourage support for Charles Darwin's theory of biological evolution Spread Nativist sentiments
Answer:
Draw the attention of Protestant churches to the plight of the urban poor.
Explanation:
The main aim and goal of the Social Gospel movement was to bring attention of Protestant churches to the difficult and dangerous solution of the urban poor. The main purpose of this movement is to combat injustice, suffering and poverty in the society. This movement started to solve the social problems such as social injustice, poverty, crime, economic inequality, alcoholism, Racial tensions slums, clean environment and child labor etc. This movement begun in the 20th century and has a great effects on he progressive-minded reformers.

If sea lamprey increase in population and decrease the native fish population, the sea lamprey population will eventually collapse (decrease rapidly). This would be an example of _______ feedback. 1. Positive 2. Negative 3. Neutral 4. None of the above
Answer:
Negative feedback
Explanation:
Feedback mechanism is activated due to the change in the system that result into an output.
A negative feedback mechanism is a pathway that is caused by deviation in the output that result in a change in output direction which is usually opposite to the initial deviation.
The process of feeding of sea lamprey on the fish started as a normal pathway the deviation started when they could not feed on the fish again as a result of reduced population and they start dying of hunger. It is a negative feedback
A certain substance is used for insulation by animals in cold climates, as well as for long term energy storage. A similar molecule makes up the cell walls of animals. This must be a:
Answer:
This question lacks options, however, it can be answered. The answer is LIPIDS
Explanation:
Lipids are one of the four biological molecules found in living systems. They are found performing variety of functions in living organisms. Lipids include the following: fats, phospholipids, steroids, oils, waxes etc. Some of the function they perform as mentioned in this question are:
- Lipids such as fats are used for long term energy storage.
- In cold climates, lipids such as fats also provides insulation in animals, helping their bodies to conserve heat.
- Lipids such as phospholipids encompass the cell membrane of animals, where they perform the role of selective permeability.

Lea el párrafo que aparece abajo y complete con las siguientes palabras que faltan: hereditaria; cromatina; equitativa; cromátidas; cromosomas; ADN; genes; duplica; brazos y centrómero
Answer:
Hereditario se refiere al proceso por el cual las características se transmiten genéticamente de padres a hijos.
Explicación:
Hereditario se refiere al proceso por el cual las características se transmiten genéticamente de padres a hijos. La cromatina consta de ADN y proteína que se replica antes de la división celular para formar duplicados de ADN que se distribuyen equitativamente entre las células hijas. Las cromátidas se refieren a las dos mitades idénticas de un cromosoma duplicado replicado y el centrómero es la secuencia de ADN de un cromosoma que une dos cromátidas hermanas entre sí y cada cromátida tiene cuatro brazos.

Explanation:
he bodies of wild-type fruit flies are colored by dark pigments, but an X-linked recessive mutation can confer a yellow, unpigmented phenotype. However, feeding silver salts to larvae results in adult flies that phenocopy the yellow phenotype. You are conducting epistasis experiments in fruit flies to understand the genetics of pigmentation. A rival research lab sends you a vial of yellow-bodied flies for your experiments. How can you tell whether these flies are mutants instead of phenocopies
Answer:
We could feed them with another type of food free of silver salts.
Explanation:
When talking about a phenocopy, we are referring to individuals who genotypically should be expressing a determined phenotype, but due to environmental influence, they express another phenotype. This is a non-inheritable phenotype, so it is not considered a mutation.
If we grow thy flies feeding them another type of food that does not include silver salts, and let them mate and reproduce, they will express the real phenotype, because they will not be influenced by the food. In the following generation, there will be dark individuals carrying the dominant allele, and yellow individuals, with the recessive genotype.
Will mark brainliest and give 18 points

The transport of molecules of a particular solute from inside an animal cell across the cell membrane to the extracellular fluid always requires energy when _____. View Available Hint(s) The transport of molecules of a particular solute from inside an animal cell across the cell membrane to the extracellular fluid always requires energy when _____. a transport protein is involved in the movement of the molecules the lipid bilayer is permeable to the solute the concentration of the solute is lower inside the cell than outside it the concentration of the solute is higher inside the cell than outside it
Answer:
the concentration of the solute is lower inside the cell than outside it
Explanation:
This question depicts the process of ACTIVE TRANSPORT, which is the movement of a substance against concentration gradient, hence, requires energy input (ATP) to occur. In this case, transporting a solute from inside an animal cell to the extracellular fluid across the cell membrane always requires energy.
This is because the concentration of solute inside the cell is much lower than that of the extracellular fluid, hence, to move the solutes against this concentration gradient (low to high), energy in form of ATP is required.
Scientists have discovered a fossil skeleton of a whale-like creature that lived in the early Eocene epoch. The skeleton shows an organism with large fore and hind limbs with distinct toes.

B.Ancestors of whales had fewer bones than modern whales.
C. Whales and their ancestors have always been ocean dwellers.
D. Whales and their ancestors have always been the largest living
Answer:

Which of the following is required in order for homeostasis to be maintained?
Select one:
An organism should have an internal environment that differs from its external environment.
There should be a constant input of stimuli to receptors so that internal conditions remain constant.

Answer:
Term Lipid Bilayer
Explanation:
A researcher recently discovered a new species of bacteria in the body of a tubeworm living near a hydrothermal vent. He compared the DNA of this new bacterial species to the DNA of four other species of bacteria. The DNA sequences came from the same part of the bacterial chromosome of all four species. According to these data, the unknown bacterial species is most closely related to
Answer:
That are more similar to each other.
Explanation:
The unknown bacterial species is most closely related to that bacteria which experience high temperature because both bacteria can live and survive in hot climatic conditions. The new species of bacteria and other four bacteria have some similar features due to similar chromosome but also have some differences due to difference in environmental conditions where they survived so those bacteria that have more similarities are more closely related to each other.
