La biogénesis es el proceso fundamental de los seres vivos que producen otros seres vivos. Ejemplo: una araña pone huevos de los que saldrán más arañas. La biogénesis es aquel principio según el cual la vida solamente se origina de una vida preexistente (que ha existido antes).
Scientific modeling is a scientific activity, the aim of which is also to make something a particular part or feature of the word easier to recognize, define, quantify, visualize, or even simulate by referencing it to an existing and usually commonly accepted knowledge.
Answer:
1) The ecosystem would have the abiotic factors of low precipitation, dry winds, and low temperatures. The biotic factors would include the animals living with the penguins such as polar bears and yaks.
2) The population would suddenly increase if either the penguin's predators had a drop in numbers or if the penguin's food source became more readily available. This growth in population would result in food becoming harder to find and predators once again growing in numbers. This would eventually cause the penguin population to shrink once more.
3) Predators would die out. Whatever organism(s) were the penguin's food source would grow in size exponentially. Other animals may suffer a drop in numbers if the penguin's predators choose to prey on them.
Answer:
1. Light
2. production of large component from smaller components
Explanation:
In the given question, the meaning of the word Photo is light and the synthesis refers to the production and combining these words form photosynthesis. The literal meaning of photosynthesis will be the production of some compounds in the presence of light.
The word photosynthesis is used by the biologists to refer to a process taking place in the green plants which involve the light for the synthesis of energy-providing molecule glucose.
Thus, 1. The light and production of the large components are correct.
Answer:
The best possible outcome for the cell in the event of mis-copied mRNA is for the mis-copied sequence to code for the same amino acid as the correct sequence would have done
Explanation: The process of transcription during which the message in DNA is transcribed as genetic codes into mRNA is sometimes not error proof. Synthesized mRNA is usually transported into the cytoplasm where the codes are translated into protein.
Each genetic code which is usually a sequence of 3 purine/pyrimidine bases codes for an amino acid. However, due to the degenerate nature of the genetic codes, more than one codon can code for the same amino acid. The degenerate nature is caused by the fact that there are 64 possible codons and there are 20 amino acids in nature. For example, UUA, UUU and UUG can be coding for the same amino acid in nature.
Hence, if a mistake occur during transcription, the best possible scenario for the cell is that the mis-copied sequence will end up coding for the same amino acid(s) as the correct correct sequence would.
