Answer:
All other things being equal the size of a population will decrease if the death rates exceeds the birthrates...
Answer:
a mutation in the germinal line changed the phenotype to bright flowers which were capable of attracting more pollinators compared to yellow flowers. Subsequently, this mutation was selected by natural selection, thereby increasing its frequency in the population
Explanation:
A mutation is any change in the nucleotide DNA sequence of the genome of a particular organism. Mutations can be divided into 1-germinal mutations (i.e., mutations that occurred in the gamete cells) which can be passed on to offspring, and 2-somatic mutations (i.e., mutations that occurred in the somatic cells), which cannot be inherited. Moreover, mutations can be neutral, deleterious or beneficial depending on the environment in which the organism lives. When a germinal mutation is beneficial, the organism carrying the mutation will have more chances to survive and reproduce (i.e., a higher adaptive fitness), thereby the organism will have more chance to pass this mutation to the next generation and the mutation will increase its frequency in the population.
An iodine solution is placed on the cut side of a potato. With in seconds, a blue-black color appears thus showing "positive test for starches".
<u>Option:</u> B
<u>Explanation:</u>
Amylose in starch is accountable in the existence of iodine for production of a deep blue shade. Within the amylose coil the iodine molecule slips. Attach a solution or directly to a potato or other products such as pasta, crackers, or flour with Iodine-KI reagent. If starch is available a blue-black color results.
If starch amylose is not available then orange or yellow will remain the color. Variations in some inorganic reactions to the reduction of oxidation, iodine may be used as an indicator for following changes in iodide ion and iodine product. Soluble solvent is applied to the starch.
The answer is b allele 100 % guaranteed, i looked it up on google.
