Some land animals, such as bears and kingfishers, eat animals that live in the water. In turn, some animals, such as crocodiles, that dwell primarily in water will eat animals that live on land. Also, many amphibians, such as frogs, and also some insects, start their life in the water, where they can prey and be preyed upon.
The answer is no, high biological fitness in one environment doesn’t have to be high in another environment.
Biological fitness is a term used in evolutionary biology and it is the quantitative representation of how a genotype (or phenotype) is successful (reproductively) in a certain environment. Fitness depends on environment so it changes if the environment changes. The fitness of a genotype is manifested through its phenotype, which is affected by the environment.
Answer:
1/2 of the offspring will have long legs and ears
Explanation:
Shown by the dihybrid cross, there are 4 possible combinations, of which, 2 will provide the offspring we’re looking for. This means we have a 2/4 ratio or 1/2 ratio.
Answer:
c.) loss of chloroplasts
Explanation:
Chloroplasts are the double membrane-bound organelles of photosynthetic eukaryotes and serve as the site for photosynthesis. The organisms that can carry out photosynthesis make the organic nutrients and do not depend on other organisms for food.
According to the given information, the photosynthetic protists become parasite in fish and start deriving nutrition from the host. If the protists continue to survive as a parasite to fish, the chloroplasts will be rendered non-significant. The parasitic mode of nutrition does not require chloroplasts and therefore, the protists would lose the organelles over generations.
