In genetics, point mutation is the generic terminology used to describe a mutation that causes a structural change in a gene. This type of mutation can impact between one and ten nucleotides. Insertion mutation, deletion mutation and substitution mutation are the three forms of existing point mutations.
B. lightweight.
C. large.
D. sweet and fleshy.
Answer:
Option B, lightweight
Explanation:
Wind basically carries away the seeds which are light weight and winged which makes them peculiar to fit in the criteria required for floating. For example seeds of swan plants and cotton wood are light weight and also have some feather like bristles which allow them to be carried away by wind to a longer distance.
Water also carries light weight seeds as they can easily float on the water for example seeds of mangrove trees.
Thus, Option B is the correct answer
Answer:
In the mentioned case, the intrinsic and environmental factors influencing the size of the population should also be included in the computer model. The population size is primarily predicted by environmental and intrinsic factors.
The size of the population of any species is monitored by the factors like birth rate, death rate, limiting factors, and their accessibility, carrying capacity of the system, rate of migration, and others. All these elements should be taken into consideration in order to determine the changes observed in the population of rabbits in a meadow.
b. False
Answer;
-Nuclei of gland cells.
Explanation;
-Enzymes are proteins that are manufactured in the ribosomes through the process of Translation. The process starts from the information contained in the DNA.
-First, the information in a DNA molecule is read and transcribed it into an intermediary molecule called messenger ribonucleic acid, or mRNA, which takes place in the nuclei. Next, the information contained in the mRNA molecule is translated into the "language" of amino acids, which are the building blocks of proteins, a process of translation which takes place in the cytoplasm in organelles called ribosomes.
Answer:
B.) nuclei of gland cells
