On the periodic table, they are found between metals and non-metals. Examples are astatine, polonium, tellurium, antimony, arsenic, germanium, silicon, boron.

Some of their properties that make them look like metals are:

i. They exist as solids at room temperature.

ii. They are shiny.

iii. They are ductile.

Some of their properties that make them look like non-metals are:

i. They are brittle.

ii. Not very good conductor of electricity compared to metals.

which organ is responsible for helping to keep the water concentration equal on each side of the cell membrane?
(please help I've been stuck on this for 2 days)

Answers

Answer:

solute membrane

Explanation:

Kidney is the main organ which is responsible for helping to keep the water concentration equal on each side of the cell membrane.

What is Kidney?

The kidneys are the main organs in the body which remove waste products and extra water from the blood in the form of urine and also help to keep the chemicals such as sodium, potassium, and calcium balanced in the body. The kidneys also secrete hormones which help control blood pressure and stimulate bone marrow to make red blood cells.

Kidneys maintain water concentration in the body. Kidneys maintain homeostasis through osmosis. Osmosis is the phenomenon of movement of water or fluid particles from a region of higher concentration to a region of lower concentration through a semi-permeable membrane.

Eventually, the film won 11 Oscars for all of its nominations. The film's box office has been more than $1 billion. In the film, there are long sequences in which not all main characters appear at the same time. And there are big scenes where everybody shows up. Thinking about the making of the film, behind the scenes, we can hypothetically break down the entire cinematic project into the following aggregate activities (We assume away all the complexities in shooting the three installments at the same time and other production details): Plan, screenplay, finance, cast, film crew, location Construction of movie sets Shooting sequence 1 Shooting sequence 2 Shooting sequence 3 Big scene sequence Postproduction & finalization before releaseWe have the following hypothetical data on time in months and cost in millions of dollars:ID IP T ES EF LS LF SLK NT NC CT CC CCRA 6.0 6.0 13.0 6.0 13.0B A 4.0 4.0 9.0 3.0 12.0C B 4.0 4.0 12.0 4.0 12.0D B 5.0 11.0 5.0 14.0 4.0 16.0E B 6.0 0.0 6.0 16.0 4.0 19.0F C,D,E4.0 4.0 19.0 4.0 19.0G F 6.0 6.0 11.0 5.0 13.5Note: IP = Immediate Predecessor; T = NT = Normal Time; ES = Earliest Start; EF = Earliest Finish; LS = Latest Start; LF = Latest Finish; SLK = Slack Time; NT = Normal Time; NC = NormalCost; CT = Crash Time; CC = Crash Cost; & CCR = Crash Cost/Time Unit (Crash Cost Rate).Copy the table to your homework and complete the following parts:By looking at the chart in part (a), find all possible paths through the network with their corresponding path times.
