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.
Answer:
D. Cup 4 had the lowest rate of photosynthesis because it had the least CO2.
Explanation:
Carbondioxide gas is the main reactant for the process of photosynthesis which decides the production of food in the leaves. If plants has high amount of carbondioxide gas and water so in the presence of sunlight it produces more food in the leaves in the form of glucose so we can conclude that the lowest rate of photosynthesis occurs due to presence of least concentration of carbondioxide gas in the cup 4.
Answer:No stretching the size of a rock can change its mass
The correct answer is D. Biology deals with all things living and their environments.
Answer:
Iron from the sand.
Explanation:
Since some types of ocean life, (plankton, algae, etc.) do sometimes not get enough iron, (nutrient) in their bodies, sand is needed for their survival. Sand has lots of iron for the animals' health, so sand is vital for their health and survival.
