A Mutation in one of an individual's somatic cells will not be passed onto the offspring.
Answer.Nucleotides Have Characteristic Bases and Pentose. Nucleotides have three characteristic components: (1) a nitrogenous base, (2) a pentose, and (3) a phosphate (Fig. ... The nitrogenous bases are derivatives of two parent compounds, pyrimidine and purine (Fig. 12-lb).
Answer:
2. It decreases genetic diversity only by reducing population size.
Explanation:
Genetic drift is an evolutionary force that works in conjunction with natural selection by changing the allelic frequencies of species over time. It is a consequence of random sampling in reproduction and the loss of some alleles by chance and not by natural selection. Normally there is a loss of the less frequent alleles and a fixation of the most frequent ones, resulting in a decrease in the genetic diversity of the population. They are accentuated in small populations, and result in changes that are not necessarily adaptive.
<span> Serratia marcescens primarily produces a bright red pigment called prodigiosin. Depending on the synthesis (partial or complete) of prodigiosin, the colour of the colony can be different. At the room temperature, prodigiosin production decrease which results in the white colour of Serratia. Serratia can also be colourless due to prolonged sunlight (UV mutagenesis).</span>
The correct answers are:
- Porosity;
- Moisture;
- Temperature;
The weathering is a process that manages to break up the rocks into smaller pieces. This process and its effectiveness and intensity are dependent on multiple factors.
The porosity of the rock can result in a very quick process of weathering. The reason for that is that the water will be able to get inside the rock, thus reacting chemically, but also if the temperatures are very low and it freezes, it will create a pressure inside the rock that will result in cracking.
The moisture is also important factor because the more water vapor there is in the air, the more the chemical reaction with the rocks.
The temperature is very importation because it can affect the rock with both very high and very low temperatures, to widen it little and than to tighten it little, which will eventually cause the rock to break up.
