The prokaryotic cells has no nucleus
The DNA sequences that make up the genetic code of an organism determine which traits the organism will exhibit. How are the instructions coded by DNA translated into an organism's physical traits? Instructions coded by DNA sequences are translated into proteins<span> which express an organism's physical traits.</span>
The classification order is kingdom, phylum, class, order, family, genus and species from large to small. So for first one, you can say it is less. For second, it is snake. Next is marking on fur and last one is animalia.
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.
Answer:
Because of the reduction or near extinction of the purple flowers noticed by the botanist Ten years after it was in abundance, this fall in the population could be caused by the unfavorable change in the plant's environment. While the pink flowers tripled because some factors in the environment were favorable for its growth.
Explanation:
From the question, it was mention that the botanist noticed at first purple flowers had more population than the pink flowers and that changed after 10 years when the population of the pink flowers tripled and purple flowers were nearly gone. Some of the causes that could be responsible are:
1. Disease and pest attack on the purple flowers.
2. The pink flowers developed a good survival mechanism even in adverse conditions.
3. Environmental stress could also come into play on the purple flowers.
4. Climate which initially supported the growth of the purple flowers had changed. Because variations exist in plants and the ideal conditions necessary for plant growths and proliferation varies among plants.
