I think it is D.... hope i'm right
Answer:
this one`s been up for debate for awhile now.
1. it depends on the organism
learning about an organism could be considered 'easier' to study in different ways. for example, if you are studying marine life, you will most likely have to keep it in a water habitat to watch it alive. If you are studying a land species, then watching from it`s natural habitat will give you more accurate results. sometimes the environment can affect an organisms internal systems more than you may think. this leads into my second point.
2. it depends on what you are trying to study
if you are trying to learn about the mating process, seasonal activity, migration, or external behavior, then monitoring it from it`s natural habitat or an area that is a close copy is your best option. but if you are looking into studying internal organs/systems or cells, then in <em>most</em> cases, the organism will need to be taken out of its natural habitat. only in very careful situations is it left in a habitat during examination.

Answer:
Presence of papillary muscles
Explanation:
- Papillary muscles are structural components of the ventricles.
- They are attached to the cusps of the mitral and tricuspid valves through connective tissue strings known as the cordinae tendeneae (heart strings).
- These muscles prevent the prolaspse of these valves during ventricular systole.
- Although they differ in number i.e. two in left and three in right ventricle, papillary muscles are present in both ventricles.
Answer:
All the answers are correct
Explanation:
An inhibitor of carbonic anhydrase would interfere with oxygen binding to hemoglobin, increase blood pH due to increased H+, increase the amount of bicarbonate formed in the blood and decrease the amount of carbon dioxide dissolved in plasma.
Carbonic anhydrase catalyses the reaction between carbon dioxide and water to form carbonic acid. Carbonic acid dissociates to form hydrogen carbonate ions and hydrogen ions. The hydrogen ions combine with haemoglobin to form weak haemoglobinic acid.
