Them the solution is hypertonic. This means that the water within the cell would exit it and go outside and the cell would shrink.

How do the two species that make up a lichen benefit from their symbiotic association? (Select all that apply.)

Marta_Voda [28]

Answer:

the correct answers are C and D: "Both partners are able to grow on substrates on which each would not be able to grow on their own", and "The fungi receive carbohydrates and, in some cases nitrogen, from the algae, while the algae gain a "home" that anchors them on the substrate".

Explanation:

Lichens are the result of a symbiotic association between algae and a fungus. These two organisms must cooperate to survive in places under certain inhospitable conditions, where otherwise, they would not be able to survive by themselves. Algaes are the photosynthetic organisms that provide carbohydrates to fungus. These last ones, get the carbon and energy they need to grow, and in exchange, they protect the algae from dehydration and radiation, and they might also provide minerals for their survival. Algae can also get a way to get attached to the substrate. When instead of regular algae, there is a prokaryotic cyanobacterium, these can also supply with fix nitrogen to fungus, in the form of nitrogenous compounds.

In DNA what pairs go together

Due to bonding interactions the nitrogenous bases on one strand of the DNA will always bind with another base on the other strand of DNA. This is due to many different enzymes that help DNA to take its structure

Jezelyn needs to create a project that shows geographic isolation in action and decides to make a video. Which of the following

kodGreya [7K]

Answer:

a video that shows penguin species that have different mating dances

Explanation:

The question is incomplete as it does not have the options which are:

a video that shows a large river that has penguin populations on both sides

a video that shows penguin species that have different mating dances

a video that shows a penguin that is laying eggs

a video that shows penguins in a tidal pool and an open ocean

Answer:

a video that shows penguin species that have different mating dances

The reproductive isolation is the factor which allows the species to evolve and form a new species, therefore, this factor is used to describe a species.

The reproductive isolation refers to a mechanism in which the species are isolated to not interbreed with the individual of other species. The reproductive isolation could be due to behavioural, psychological, physical or genetic differences. evolved as an adaptation.

In the given cases, the penguin species which shows different mating dances is considered to be reproductively isolated as the different dance rituals evolved as behaviour to prevent them from mating.

Thus, the selected option is correct.
