The answer is A. DNA→ RNA→ protein→ trait.

According to the central dogma of molecular biology, DNA codes for RNA which codes for proteins.
The sequence of DNA is transcribed into RNA during the process of transcription. RNA is later translated into proteins during the process of translation. The protein is responsible for some trait.

Why does DNA flow toward the positive electrode of the gel chamber?

Digiron [165]

Answer:

DNA molecules have negative charges, and so when placed in an electric field they migrate toward the positive pole.

Explanation:

Electrophoresis is a technique that uses differences in electrical charge to separate the molecules in a mixture. DNA molecules have negative charges, and so when placed in an electric field they migrate toward the positive pole. The rate of migration of a molecule depends on two factors, its shape, and its charge-to-mass ratio.

A gel, which is usually made of agarose, polyacrylamide, or a mixture of the two comprises a complex network of pores, through which the DNA molecules must travel to reach the positive electrode. The smaller the DNA molecule, the faster it can migrate through the gel. Gel electrophoresis, therefore, separates DNA molecules according to their size.

Which of the following statements is true?

KIM [24]

Secondary consumers receive less energy from the food chain than primary consumers.

Primary consumers are herbivores, meaning they eat the plants that have 100% energy.

Secondary consumers are either omnivores or carnivores. This means that they eat both animals and plants. In the situation that a secondary consumer is a carnivore, the secondary consumer is receiving less energy from the primary consumer.

Hope this helps!

Crossing a BB male with a Bb female:

The Punnett Square will look like this:

BB BB

Bb Bb

The percentage will be as follows:

- You will have 50% homozygous dominant (BB)

- You will have 50% heterozygous (Bb)

Now, for the phenotype, you will have 100% black fur, since B is dominant and is prevalent in 100% of all the breeds.

For the genotype, you have 50% BB and 50% Bb
