Answer:
C
Explanation:
When two species share a common niche, then one is bound to exclude the other. This is due to the stiff competition for resources. The species with a slight advantage in acquiring the resources will edge out the other species from the environment. This has been demonstrated by George Gauss using two Paramecium species grown in the same media in the lab. <em> P. aurelia</em> outcompetes <em>P. caudatum</em>
Answer:
b) DNA polymerase can synthesize DNA in the 5' to 3' direction
DNA polymerase is only able to synthesize a new strand of DNA and not mRNA. It is only able to do this in the 5' to 3' direction. The leading template strand runs in the 3' to 5' direction and so the new complementary strand is synthesized in a 5' to 3' direction in one continuous run, following the replication fork as it 'unzips' the DNA.
hope it helps btw i did this test and i got it correct
check my screenshot below
please mark me brainliest
Explanation:
It is the comparison of the nucleotide sequences in DNA
B represents the growth shown in plants without fertilizer even in similar conditions. Experiment B is important because it helps bring the experiment to a conclusion that plants react better with fertilizer when growing in it’s early stages.
Abiotic are the non-living physical and chemical factors that can affect the ecosystem, such as amount of water, temperature, amount of sunlight, etc.
Biotic are the living organisms inside the ecosystem, and can include humans, animals, and plants.
