Answer:
- Glacial deposits and scratches in the bedrock from an ice sheet match in distant regions
- Fossils of marsupials were originally the same across South America and Australia
- Cratons match across the edges of continents
Explanation:
South America, Africa, Antarctica, and Australia were all once part of one super-continent. This super-continent has been named Gondwanaland. As the geological processes got more intensive though and Gondwanaland separated into smaller land masses, continents, which we now know as the continents on the Southern Hemisphere. There are numerous clues that confirm that these continents were once connected. Some of the clues are the matching cratons on the edges of the continents, the glacial deposits and scratches in the bedrock are also matching, lot of fossilized flora and fauna from the same species have been found in several of these continents, the marsupials in South America and Australia etc.
<span>The graph portrays
predation. The relationship shows that an
increase in the population of zebra
results in a subsequent increase in the lion population, and vice versa. This,
therefore, means that the lion population
is dependent on the zebra population due to an interaction (predation). The lion population
will always be lower than that of the zebra because of the inefficiencies of energy transfer up the trophic levels (exhibited by a
typical energy pyramid). </span>
Answer:
plankton
Explanation:
plankton are eaten by pretty much everything as they are so small. they also get food through photosynthesis therefore they do not eat any other animals. i am pretty certain krill eat them but i dont know
Explanation:
Compare and contrast a frameshift mutation and a single nucleotide substitution mutation in a DNA sequence encoding a protein. How many nucleotides would be inserted or deleted in each? How many amino acids in the protein sequence would be altered in each?
