Answer:
r-selected
Explanation:
R-selected species are organisms The carrying capacity is not a limiting factor. The life span of these individuals is short and in general there is no care with the offspring. They aim to exploit empty niches and produce a large number of offspring each cycle, even though few of them survive to adulthood. Informally it can be said that this is a strategy based on quantity rather than quality. Examples of r-selected species: insects and most fish.
Answer:
The correct answer is option A. demonstrates that the E. coli cultures were viable.
Explanation:
In this lab experiment or culture, Plate I and plate III demonstrate, that E.coli bacteria can grow both in the presence and absence of plasmid DNA if ampicillin is not there.
So, which means that plasmid DNA is not required for the growth of E.coli in absence of ampicillin. The presence of growth in wild type (plate 1) and a plasmid containing bacteria (plate 3) in media without ampicillin shows that bacteria are viable in nature.
Gametes, spores I think. I'm pretty sure that's it.
The lichens show mutualism and they are found in every biome of the Earth. The lichens have algae and fungus associated with them and they live in a mutualistic relationship with each other. Lichens can grow on soil where no other species can grow like rocks, barren soils and they enrich the soil on dying where other plants and trees can grow.
Lichens being pioneer species change the environment by building up the soil and liberating nutrients. Also the lichens contribute to the chemical weathering of the soil releasing phosphate along with erosion and weather conditions.
When the simple plants die, the wildflowers and other plants start growing replacing lichens or mosses.
From the above explanation it can be concluded that lichens alter the abiotic environment and favor other species of plants to grow by breaking down rocks from soil and providing nutrients.
