BEFORE equilibrium has been reached in this container: (Circle a letter for each) 1. Movement of glucose across the membrane in
qwelly [4]

Hello. You forgot to put the image so that this question can be answered, but I will describe what the image shows.

The image shows two types of "cups" that have a type of connection between the two. In cup A there is 1 mole of glucose and 1 mole of fructose. In cup B there is 0.1 mol of glucose and 1.5 mol of fructose.

Answer:

A. Solution A to Solution B

Explanation:

Balance is achieved when the "cup" with the lowest concentration of glucose receives glucose from the "cup" with the highest concentration, to the point that the two glasses establish equal concentrations of glucose between them.

We know that cup B has a lower concentration of glucose, which indicates that the movement of this solute was from cup A towards cup B. With this we can conclude that the letter A is the correct answer.

ocal and distant brain control in melanoma and nsclc brain metastases with concurrent radiosurgery and immune checkpoint inhibit
BartSMP [9]

Stereotactic radiosurgery (SRS) and immune checkpoint inhibitors (ICI) are increasingly used to treat brain metastases, however there is a paucity of prospective data on the effectiveness of these treatments in terms of cancer control.

Data from patients treated with SRS for non-small cell lung cancer (NSCLC) and melanoma brain metastases at a single facility from May 2008 to January 2017 were retrospectively examined. The impact of concurrent ICI within 30, 60, or 90 days of ICI administration on local control and remote in-brain control is examined using a parametric proportional hazard model. The regression model takes into account other patient and lesion characteristics as covariates and makes adjustments.
