Answer:

The correct answer is a. donates hydrogen ions to solutions

Explanation:

There are many definitions of what acid is, but the most common one is that an acid donates hydrogen (+) when it dissociates in solutions. Adding hydrogen or (+) to a solution will lower the pH value and then it will make the solution more acidic in the pH range.

If the green allele is designated as G, and the aurea allele is designated as GA , assign genotypes to the phenotypes listed. Dr

Katyanochek1 [597]

Answer:

in the mutated snapdragon plants, the green leaves started becoming yellow. this conditioned plant is known as, aurea, which has less chlorophyll than green plants.

Crosses had done between various combinations of green and aurea plants and the result was- green x green = all green

aurea x aurea = 2/3 aurea, 1/3 green

green x aurea = 1/2 green, 1/2 aurea

here, the green allele is G, and the aurea allele is GA,

according to the question, in the cross of plants,

the green plants produced all green but some of the crosses of aurea phenotype also gave the green phenotype.

so it can be concluded that the green phenotype (the wild type) came from the recessive allele. No instances of incomplete dominance or codominance were shown.

Thus, the following genotypes would have their phenotypes, as follows:

GG - green

GAGA - aurea

GGA - aurea

In the mouse, gene B can produce black pigment from a colorless precursor molecule. A mouse having at least one B allele can pro

Lyrx [107]

Answer:

Black

Explanation:

In the mouse a certain colorless pigment precursor exists.

If the B allele is present: precursor is converted into black pigment.
If the genotype is bb: albino

In addition:

If the A allele is present: black pigment is converted to brown pigment
If the genotype is aa: black pigment is not converted and mouse remains black

If the mouse has a genotype aaBB, the colorless pigment is converted to black (because there is at least one B allele) but the black pigment cannot be converted into brown (because there's no A allele), so the mouse will have black fur,

mart [117]

Answer:

The summary of something like the particular question is demonstrated in the following portion on either the clarity.

Explanation:

Inspiration depends on either the diaphragm contracting, as well as the influence including its external intercostal has been limited throughout normal breathing.
Maximum inhalation or even just expiration time depth, as well as rate, are fairly directly proportional to one another because.
We may link the whole observation to something like the sequence of expiratory versus inspiratory movement as it takes much longer than either the inspiratory speed throughout our sample since expiration becomes passive yet requires having to return to something like the steady levels.
