Answer: why it is hard to use dichotomous key in the lab are;
If the organisms you want to use it for are similar.
If you can't see the little characteristics posses by the organisms you are using it for.
If all the pictures does not reveal all the important features of the organisms.
It is very difficult to use it to determine the anatomical structure.
Explanation:
Dichotomous key is an important method that is use in biology to identify organisms by separating or dividing the organisms into two groups. It is a tool created by scientists to help them identify organisms or objects. Once the organisms are group into two, more information is revealed more individually.
The answer is: b) solutes move out of the cell
Smoking ruins your lungs making it harder to breath and get oxygen
you need oxygen when you exercise so you don't faint
smokers get less so it is harder for them, its like trying to exercise while breathing through a sponge or a straw os
Answer:
The statement that will show the best accurate criteria is patient's respiratory rate is 16 breaths/minute and blood pressure is 130/72 mm Hg.
Explanation:
Adrenergic drugs are drugs that cause the stimulation of the sympathetic nervous system, which is also known as adrenergic nervous system by performing or mimicking the activities of the epinephrine and norepinephrine, or interfering with their release.
It should be noted that, epinephrine and norepinephrine are also known as adrenaline and noradrenaline, this is because they are secreted by the adrenal gland, and this gives rise to the term adrenergic.
Examples of adrenergic drugs are phenylephrine, clonidine and oxymetazolin among others.
Answer:
D Flow of protons across an electrochemical gradient
Explanation:
The chloroplast adenosine triphosphate (ATP) synthase uses the electrochemical proton gradient generated by photosynthesis to produce ATP, the energy currency of all cells. Protons conducted through the membrane-embedded Fo motor drive ATP synthesis in the F1 head by rotary catalysis.
In chloroplasts, photosynthetic electron transport generates a proton gradient across the thylakoid membrane which then drives ATP synthesis via ATP synthase.
The light-induced electron transfer in photosynthesis drives protons into the thylakoid lumen. The excess protons flow out of the lumen through ATP synthase to generate ATP in the stroma.
Majority of ATP is produced by OXIDATION PHOSPHORYLATION. The generation of ATP by oxidation phosphorylation differs from the way ATP is produced during glycolysis.
Electrons are passed from one member of the transport chain to another in a series of redox reactions. Energy released in these reactions is captured as a proton gradient, which is then used to make ATP in a process called chemiosmosis.
