Answer:
The correct answer is to: characterized them and study them on the based of shared characteristics, similarities and phylogeny.
Explanation:
Arranging different type of organisms on the basis of their shared characteristics such as physical similarities, anatomical characters, phylogeny, habitat they share and many more, in order to study them easily known as classification.
Classification helps understanding the diversity of living organisms with the help of their features, similarities and differences. Aim of the classifying organisms is to, identification of organisms, to establishing the evolutionary relation among different type of organisms and studying the phylogeny.
Plants, humans, animals, and microorganisms is the answer to this question
Answer:
Norepinephrine
Explanation:
Nerve cells and circulating hormones are the one responsible for vasoconstriction of the vessel walls, as they do not enter the tunica media of the blood vessel, the nerves do not synapse directly on the smooth muscle cells. Instead, they release the neurotransmitter, norepinephrine, which diffuses into the media and acts on the nearby smooth muscle cells, which result in contraction of the entire muscle cell layer and thus reducing the radius of the vessel lumen.
After he ate, glucagon from the cookies increased his blood sugar levels
Insulin was secreted after he ate the cookies because his blood glucose was high.
Answer:
Experimental groups: type of dogs
Dependent variable: hearth rate
Independent variable: the amount of caffeine
Explanation:
The dependent variable is the variable being measured or tested in a given study, while the independent variable isn't changed by the other variables. In this case, the heart rate is dependent on the amount of caffeine, which is then the independent variable. The experimental groups are the groups exposed to the independent variable.
