Answer:
Protons have a positive charge and are found in the nucleus
Explanation:
Answer: TT: 1/4; Tt: 2/4;tt: 1/4
Explanation:
The Punnett square is a diagram that is used in the predictions of genotypes. In this scenario, if we have a tall plant (TT) is crossed with a short plant (tt), after using the Punnett square, the genotype that we will get are as follows:.
TT, Tt, Tt, tt
Therefore, the correct option is option D "TT: 1/4; Tt: 2/4;tt: 1/4
<span>Farmer Brown might be hesitant to clone his corn because cloning eliminates the ability to sexually reproduce and provide genetic variability. There will be no variability in genes in these clones, because given that they are exact copies of their "parent," they will all be identical, without any difference or variation. This farmer doesn't want that to happen, which is why he is hesitant to take Farmer Green's advice.</span>
Answer:
Cold climates favor mechanical weathering.
Explanation:
A cold, dry climate will produce the lowest rate of weathering. A warm, wet climate will produce the highest rate of weathering. The warmer a climate is, the more types of vegetation it will have and the greater the rate of biological weathering
The right answer is Half-life.
Half-life is the time taken by a substance (molecule, drug or other) to lose half of its pharmacological or physiological activity. Used by extension in the field of radioactivity, the half-life, also called radioactive half-life, is the time at which half of the radioactive nuclei of a source have disintegrated.
<span>The term half-life is often misinterpreted: two half-lives do not correspond to the full life of the product. The half-life is in fact the median of the life of a product, that is to say the duration below which there remains more than 50% of the product, and beyond which there remains less than 50%.</span>
