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:
Eosinophils
Explanation:
These are type of White blood cells W.B.C ,present almost 2% of white cells . About twice the size of red blood cells , Nucleus is bi lobed . They are often used for parasite attack , Inactivate inflammation and production of substances .
The two ways the endocrine system and the nervous system are different in communication, is that the nervous system responds rapidly to short-term changes in the body by sending electrical impulses. And with the endocrine system, it takes longer, so it's a long-term effect until it notices any changes and when it does, it sends chemical messengers known as hormones into the body.
Now, how they are similar, is because both the nervous and endocrine systems work together to maintain homeostasis.
A water molecule, because of its shape, is a polar molecule. That is, it has one side that is positively charged and one side that is negatively charged. The molecule is made up of two hydrogen atoms and one oxygen atom. The bonds between the atoms are called covalent bonds, because the atoms share electrons.
Answer:
carbon, hydrogen, nitrogen and oxygen
Explanation:
mostly, combination of carboxylic and amine groups
