It is a mating in which an individual showing a dominant phenotype is crossed with an individual showing its recessive phenotype. In a test cross, the unknown individual must be of a dominant phenotype because if the phenotype is recessive the genotype will have to be homozygous recessive.
Answer:
RNA polymerase
Explanation:
The RNA polymerase is an enzyme used in the transcription of genes in DNA to make mRNA. RNA polymerase binds on the promoter region based on the sequences that can be identified by the enzyme’s active site. A mutation can distort the interaction between the promoter region and the enzyme’s active site hence throttle up or inhibit transcription.
The above-mentioned method is used to analyze the streak of a mineral. Streak can be different from that of the color of the mineral, itself. It is used for soft minerals, and such minerals have their characteristic streaks. So the correct answer to your question is D.
Answer:When added to water, an acid releases hydrogen ions. Hydrogen ions in water combine with the water molecules to form hydronium ions, thereby decreasing the pH and increasing the acidity of water.
Explanation:
The answer should be Tidal Lock (A), because this is when the event of the orbital position of an object (Earth) is matching the same rotation period as the other object (Moon). When these rotations are the same, the moon will always be facing the same direction as the Earth. I believe you made a typo because Tidal Rock is not even considered to be a term in science. It is not a Solar Tide (that isn't even concerned with the moon facing the Earth), magnetosphere isn't even related to the moon but its magnetic field, and a tidal "bulge" is the complete opposite and has the moon facing the completely opposite direction.
