Answer: A. Alice can pour the water into a graduated cylinder to find the volume

Explanation: If you put water into a graduated cylinder, you get accurate numbers. This helps with the equation because estimating isn't always the best way to go. Putting a ruler in the water wont help because you don't know what number the water started at before the displacement. The thermometer won't work either because that is used for temperature.

Your aunt grows sprouts hydroponically. from where do her plants get nutrients?
larisa [96]
Hydroponics way of growing, is way of farming, in which plants are grown in nutrient rich water. So, in Hydroponic growing of sprouts, sprouts get their nutrients from the nutrients supply like liquid fertilizers which are mixed with the water. It is one of the advantage of hydroponic means of growing because, unlike in soil system, the plants root does not have to work hard to get nutrient from underground. The easy availability of nutrients and other condition like water, pH level etc makes plants grow faster are fuller.

Also, advancement of technology have made it possible to prepare built-in hybrid hydroponic system which have multiple ways of delivering nutrient to specific plants.

You are given two true-breeding groups of rabbits. The first group has floppy ears and white coat color. The second group has st
malfutka [58]

Answer:

Option E, Floppy ears are dominant over straight ears; coat color is determined by incomplete dominance

Explanation:

Let the allele for floppy ears be "F" and the allele for straight ears be "f"

And Let the allele for black coat color be "B" and the color for white coat color be "b"

Now, the cross is carried out between the first group having floppy ears and white coat color (FFbb) and the second group having straight ears and black coat color (ff BB)

The 16 offspring have genotype FfBb

Phenotype of 16 offspring is Floppy ears and grey coat

Ff represents the floppy ear , thus "F" is dominant over "f"

Bb represents the grey color which is a case of incomplete dominance in which none of the real trait i.e black or white is expressed.

Hence, option E is correct

According to the lac operon model proposed by Jacob and Monod, what is predicted to occur if the operator is removed from the op
stepan [7]

The right answer is The lac operon would be transcribed constitutively.

An operator is a nucleic acid segment to which a regulatory protein that modulates downstream gene expression is bound. it can either stimulate or inhibit the production of the gene product thus controlled.

If the operator is absent, there will be no more regulation of the operon, so the transcription of the operon will not be regulated, and the synthesis will be continuous and constitutive.

Given the number of oscillations a wave completes in a period of time, you can determine the amplitude. wavelength. frequency. e
Advocard [28]
I believe it is the frequency, because when a oscillation occurs that is the starting point to determine when another wave is to come.
