Because those are traces of life meaning that there was life living there once, that life wouldn't have been able to survive there with how Antarctica is now.

Blood flow
horrorfan [7]

Answer:

D. Tricuspid → right ventricle → pulmonary valve → pulmonary circulation

Explanation:

The circulatory system is the system of organs and blood vessels which is associated with the circulation of the blood in the body.

The circulatory system is divided into two portions: the systemic circulatory system (body) and the pulmonary circulatory system (lungs).

The vena cava brings the oxygen-poor blood from the body to the right atrium from where the blood is transferred to the same side of the ventricle controlled by the tricuspid valve (atrioventricular valve).

From the right ventricle, the blood is pumped to the pulmonary artery which transports the blood to the lungs where the oxygen will be exchanged.

Thus, Option-D is correct.

Given a very unusual cell with an intracellular fluid containing 1 mM calcium phosphate and an extracellular fluid containing 10
vladimir1956 [14]

Answer:

M.P = 140.46 Vm

Explanation:

Membrane potential can calculated using the following equation:

<em>(61/z) ln ([X]out/[X]in)</em>

where z is the charge of Ca2+ ion and X represent the concentrations By applying necessary calculations…

Membrane potential = (61 / 2) ln (100 x 10^-3 / 1 x 10^-3)

                                  = 30.5 x 4.60 = 140.46 Vm
