Answers:
Zooplankton help other populations survive by keeping out other herbivores
Explanation:
This is because a keystone species are species that have large effect on the the habitat and through its effect they help to keep the ecosystem in existence. They make sure that the ecosystem exist. They help populations survive by keeping out herbivores and feeding on the algae. They help drive nutrients cycle and transfer energy from algae to invasive fish.
The component of the above experiment that is the dependent variable is the average number of earthworms in each type of soil.
The dependent variable is the variable with a value that depends on other components in an experiment.
Answer:
A pairs with U
C pairs with G
T pairs with A
Explanation:
Transcription is the first process of gene expression and it involves making a complementary strand of mRNA from a DNA template. It begins when an enzyme called RNA polymerase binds to the promoter region of the DNA and signals it to unwind exposing Its nucleotide bases. RNA polymerase reads the bases and adds nucleotides to the RNA strand using complementary base pairing.
Complementary base pairing is a phenomenon whereby hydrogen bonds pair Adenine and Thymine and also Guanine and Cytosine in DNA i.e. A-T, G-C. However, in the newly made RNA molecule, Thymine base is replaced by Uracil, U.
In this case (question),
If the RNA polymerase reads Adenine (A), it pairs it with Uracil (U) in the RNA molecule.
If it reads Cytosine (C), it pairs it with Guanine (G) in the RNA molecule.
If it reads Thymine (T), it pairs it with Adenine (A).
The choice that is correct would be A : When the egg hatches is will immediately become an adult insect. because that is not natural to happen but it dose every other decade.
dose this help you in any way?
