A. land plants, tiny water plants
a. slug, frog, newt
b. plants, slug-insect-water fleas, frog-fish-newt, perch-fox, heron
c. water fleas, diving beetles
d. heron, perch
e. one thing that could happen if all frogs suddenly died is that there would be an overpopulation of slugs, insects, and beetles. another thing that could happen would be that foxes would only rely on getting slugs for food so the slugs would soon go extinct and the plants would possibly over populate.
hope this helps!!
Answer:GGATCGA
Explanation:
The complementary double helix of the DNA are antipararell to each other.
Chargaff's rule state that Adenine always pairs with thymine (double bond) and Cytosine always pairs with guanine (triple bond).
Therefore if a DNA molecule is CCTAGCT, then the sequence on the complementary strand of DNA will be GGATCGA as written below
5' CCTAGCT 3'
3' GGATCGA 5'
Both organs are made up if several kinds of tissues. :D
Answer:
the fundamental unit of heredity
Explanation:
DNA is a double stranded helix structure. Each strand is made up of a string of nucleotides.
A gene is a region of DNA, usually tens of thousands of nucleotides long. At the simplest level, one gene encodes for one trait. Therefore, the gene can be described as the fundamental unit of heredity.
Genes work by coding for specific proteins, which carry out essentially all the functions in the cell.
