Answer:
A. A marine biologist measures the lengths of the dorsal fins of a number of tiger shark: In this case, the biologist needs to sample the sharks, make measurements and organize in tables the data obtained from the two variables measured in each of the analyzed individuals.
C.An ornithologist, a scientist who studies birds, draws a sketch showing the colors of a bird’s plumage.
in this case the ornithologist had to make observations of birds of different species and through schemes report and organize according to the species what color of plumage they have.
D.An ecologist uses a computer to make a graph of the measurements of the rings of a tree:
The graph is the way in which the scientist systematizes the data for the analysis of the tree rings. these trees had to be sampled
Explanation:
Answer:E. commensalism
Explanation:
In commensalism, one is helped and one is not bothered, so since the wasp is not bothered and the mite is helped its E.
Answer:
The Various Kinases that is activated after the breaks in DNA is after the activation of ATM serine threonine kinase which helps in phosphorylation of other DNA replication check proteins, p53 protein (tumor suppressor protein) etc.
Explanation:
ATM activated by MRN complex at the site of DNA double stranded breaks by phosphorylation. MRN complex activity on ATM induces a conformational change in ATM kinase. So it can bind to its various substrate molecules that helps in DNA replication cycle arrest.
ATM phosphorylates CHK2 protein a product of CHEK2 gene, also known as effector kinases that phosphorylates and helps in deactivation of cyclin dependent kinases (CDKs) that helps in the prevention of progression of mitotic phase.
ATM also phosphorylates the inhibitors of p53 proteins which leads to the overexpression of p21, an inhibitor of (CDKs).
Answer:
1) a hypothesis is a question that you make before doing an experiment
2) independent and dependent variables
