North component: y = 15.0 m * sin 55.0º = 12.3 m West component: x = 15.0 m * cos 55.0º + 7.00 m = 15.6 m
so his heading, measured from West, is Θ = arctan(y/x) = arctan0.787 = 38.2º N of West
and measured from North is φ = arctan(x/y) = arctan(1.27) = 51.8º W of North
Answer:
Single-celled organism are not classified as an animal because animals are multicellular organisms i. e. made of more than one cell while single celled organisms are unicellular organisms i. e. made of one cell. In single celled organisms, one cell perform all activities while in animals special cells are responsible for particular function. There are some single celled organisms are autotrophic while animals are heterotrophic in nature.
Neither is correct actually
Answer:
The main difference between Prokaryotic and Eukaryotic cell is that, eukaryotes contain membrane bound organelles like nucleus where as prokaryotes do not. The genetic material is present at the center and is called nucleoid in prokaryotes.
Explanation:
Example of prokaryotes include bacteria and archea bacteria. Examples of eukaryotes include plants and animals. Prokaryotes lack organelles such as mitochondria, endoplasmic resticulum and lysosomes which are present in eukaryotes. Both the groups contain ribosomes but its 70s ribosome in prokaryotes and 80s ribosomes in eukaryotes.
Answer:
Together
Explanation:
All of the organisms need each other to survive, all of the natural cycles are necessary to keep the Earth in balance.
