If a certain species of brown bird is crossed with a white one all the offspring are tan. If these offspring were crossed and produced 20 individuals in the f2 generation what colors and ratios would be expected?
Answer:
In the f2 generation:
10 of offspring would be tan (ratio form - 10:20)
5 of offspring would be white (ratio form - 5:20)
5 of offspring would be brown (ratio form - 5:20)

Which of the following best describes a precipitate?
A measure of mass per unit of volume
A solid separated from a solution
A form of weather
A clear indication of a physical change
Answer:
In chimica, un precipitato è un solido insolubile che emerge da una soluzione liquida. L'emergenza del solido insolubile dalla soluzione è chiamata precipitazione. Spesso il precipitato emerge come una sospensione. I precipitati possono formarsi quando due sali solubili reagiscono in soluzione per formare uno o più prodotti insolubili.
Explanation:
A solid separated from a solution best describes a precipitate. So, the correct option is B.
What is Precipitate?Precipitation is the process of formation of a solid substance in a solution, either by physical mixing of low-solubility chemicals or by a chemical reaction of two or more compounds. Precipitate refers to the solid that eventually forms as a result. A solid that separates from a solution during a chemical reaction is known as a precipitate.
When two or more compounds are combined, they react to form an insoluble product, which is how it is formed. A precipitate may take the form of a suspension in solution or a solid that settles to the bottom of a solution. It can be removed from a liquid using a number of techniques, including filtration and centrifugation. Many chemical reactions require precipitates, which are often used to separate, purify, or identify different compounds.
Therefore, the correct option is B.

Mendel demonstrated which of the following about inherited traits? Check all that apply.
certain traits are more likely to appear than their alternatives.
some traits show blending inheritance.
traits segregate among the offspring of a cross.
traits can be hidden in some generations, but subsequently reappear unchanged in future
generations.
parents that both have the same trait can have offspring with an alternative trait.
Answer:
The correct answer would be -
certain traits are more likely to appear than their alternatives.
traits segregate among the offspring of a cross.
traits can be hidden in some generations, but subsequently, reappear unchanged in future generations.
parents that both have the same trait can have offspring with an alternative trait.
Explanation:
Mendel is known as the father of genetics for his tremendous work in the field of genetics by performing experiments on the pea plants which contribute to the make the law of inheritance. According to all three laws of inheritance and experiments performed by Mendel, he demonstrated inheritance patterns in the traits or the alleles inherited to the next generation.
Certain traits that are dominant are more likely to appear than their recessive alternatives. Trait segregates when gametes form during the cross. In heterozygous cases, some traits can be hidden but can reappear unchanged in future generations.

How do the vrg and drg control and regulate the respiratory rate?
Answer:
The ventral respiratory group (VRG) and the dorsal respiratory group (DRG) within the medullary rhythmicity area cooperate to establish the pattern for spontaneous ventilation and basal rate of ventilation which may be adjusted by impulses from related respiratory control centers in the pons; the ventral respiratory group (VRG) contains both inspiratory and expiratory neurons; the autorythmic inspiratory neurons stimulate the diaphragm and external intercostals for approximately 2 seconds to cause inspirations and then the antagonistic expiratory neurons fire for approximately 3 seconds to permit passive or stimulate active expirations; thereby inspiratory and expiratory neurons cooperate in a negative feedback control relationship, setting the basic rhythm of respiration (spontaneous ventilation, resting or tidal breathing (eupnea)); the dorsal respiratory group (DRG) neurons are involved in altering the pattern for ventilation in response to the physiological needs of the body for O2 and CO2 exchange and for blood acid-base balance; these neurons stimulate neurons in the ventral respiratory group (VRG) to achieve those effects; they are responsive to sensory information from chemoreceptors and mechanoreceptors.

Answer:
996
Explanation:
first we can take 84 out of the total of 1200 because they didnt even take a exam and then we can take 120 out of that because those are the students who failed which leaves us with 996 students who passed both subjects.

Mutations rII1 and rII2 are known to fall into the rIIA and rIIB cistrons (genes) respectively. Cells of E. coli B are infected simultaneously with phage strains rII1 and rII2 at a high moi. The progeny phage are collected and used to infect cells of E. coli K. This infection is also carried out at a high m.o.i., and the resulting phage are collected. These progeny are diluted and plated on both E. coli B and E. coli K. Do you expect more plaques on strain B, on strain K, an equal amount on both or is it impossible to tell?
A. E. coli B
B. E. coli K
C. Equal on both
D. Can't tell
Answer:
the answer is A. E. coli B
Explanation:
The multiplicity of infection (MOI) refers to the ratio between the numbers of viruses used to infect E. coli cells and the numbers of these E. coli cells. Benzer carried out several experiments in order to define the gene in regard to function. Benzer observed that E. coli strains with point mutations could be classified into two (2) complementary classes regarding coinfection using the restrictive strain as the host. With regard to his experiments, Benzer observed that rII1 and rII2 mutants (rapid lysis mutants) are complementary when they produce progeny after coinfect E. coli K (where neither mutant can lyse the host by itself). The rII group of mutants studied by Benzer does not produce plaques on E. coli K strains that carry phage λ (lysogenic for λ), but they produce plaques on E. coli B strains. This study showed that rIIA and rIIB are different genes and/or cistrons in the rII region.

I need to breed all white mice for the genetics class visiting from a High School in a few weeks. I only have white males and black females. (Black is the dominant fur color) What would the genotype of the parent mice need to be to get the most white mice for my money? What genotypes would the
parents need to give only heterozygous offspring? Show each of these crosses (only heterozygous offspring, and maximum white offspring) on the Punnett squares below.
Answer:
Punnet squares for maximum white mice are above, but H e t e r ozygous white mice aren't possible if black is dominant. Because black will be expressed, rather than white.
If white can be dominant and black can be recessive then h e t e r ozygous white mice are possible. (Punnet squares for this situation are also attached)

dioxide. Carbon dioxide absorbs heat radiated from the Earth's surface.

OC.
Carbon and oxygen have properties that are different from those of carbon dioxide.
OD

Submit
Answer:
OC
Explanation:
That is just because carbon and oxygen on their own are different as oxygen has more mass or weight than carbon and besides it is 2 oxygens and a carbon that will give you carbon dioxide.
Plss help me with this carbon cycle!!!!
Answer:
Plants photosynthesize, so they need, thus absorbs carbon dioxide. Marine plants also need carbon dioxide for photosynthesis so they absorb. Dead plant and animal matter decay to release carbon dioxide as a result.
A carbon footprint refers to the greenhouse gas emissions caused both directly, and indirectly, by an individual, a product, an organization, or an event.
