In the simulation, when protein molecules were evenly distributed on both sides of the membrane, was the solution isotonic, hypertonic, or hypotonic? Which direction was water flowing?
Answer:
1. Diffusion is the process of a substance moving from an area of high concentration to an area of lower concentration. Osmosis is a type of diffusion where water moves across a semipermeable membrane still from an area of high concentration of water to an area of lower concentration of water. This corresponds to water moving from an area with a low concentration of solute to an area with a higher concentration of solute.
2.
a. A semipermeable membrane allows some substances to pass through it.
b. The plasma membrane of a cell allows small uncharged molecules to pass through it, but not large molecules and not charged ions.
3.
a. The protein molecules were evenly distributed on both sides of the membrane, so this solution was isotonic.
b. In an isotonic solution, water moves both in and out of the cell, which was observed in the simulation.
4.
a. The protein molecules were more highly concentrated on the inside of the cell, so this solution was hypotonic.
b. In hypotonic solutions, water moves into the cell to help dissolve the higher amount of solute inside the cell, which was observed in the simulation.
5.
a. A semipermeable cell membrane is important to allow some molecules, like proteins, to be more highly concentrated inside the cell than outside the cell. If the cell membrane were permeable, the molecules on the inside of the cell would exit the cell and be evenly distributed in the cell and in its environment.
b. If the cell membrane were not permeable at all, the cell would not be able to receive nutrients from its environment.
Explanation:
When protein molecules were evenly distributed on both sides of the membrane, the solution is isotonic.
In isotonic solution the concentration of solutes on side remain same .There is no net gain or less of water in isotonic solution.What will be the direction of water flow in isotonic solution?The water will flow freely across the cell membrane without any change in the concentration of solutes.In isotonic solution the cell neither shrink nor swell because the water concentration will remain same.To know more about isotonic solution here

cancer drug Vinblastine interferes with the
synthesis of microtubules. Which process does
Vinblastine interfere with during the cell mitosis?
Answer:
The correct answer is - disrupting microtubule assembly and proper formation of the mitotic spindle and the kinetochore.
Explanation:
Vinblastine is known for treating cancer cells by sending them to apoptosis. It interferes with the synthesis of microtubules. It binds to the microtubular proteins of the mitotic spindle that causes disrupting microtubule assembly.
It also prevents from proper formation of the mitotic spindle and the kinetochore which is essential to separating chromosomes during anaphase. They arrest mitosis and cause cell death.

f) Los chimpancés pasan de generación en generación las técnicas que han aprendido para capturar termitas usando varitas mojadas con saliva.
g) Al acercarse el verano, muchas aves migratorias dejan su hábitat de crianza y se dirigen hacia sus territorios de invierno, que pueden estar a cientos o incluso miles de kilómetros de distancia. Muchas de estas aves viajan por primera vez, porque salieron del cascarón sólo unos meses atrás.

Membrane proteins called pumps use energy to move hydrogen ions to one
side of the membrane. Which term describes the difference between the
numbers of hydrogen ions on opposite sides of the membrane?
A. lon concentration
B. Concentration gradient
C. Homeostasis
D. Equilibrium
Answer:
Explanation:
Pumps, also called transporters, are transmembrane proteins that actively move ions and/or solutes against a concentration or electrochemical gradient across biological membranes. Pumps generate a membrane potential by creating an electrochemical gradient across the membrane.

Match each conservation effort with the resource it could directly help save.
saving forests
conserving freshwater aquifers
reducing CO2 emissions that contribute to climate change
Walk or use a bicycle for short-distance
travel.
Use computers for communication and
taking notes.
Treat sewage water and use it in factories.
Answer:
walk or bike reduces CO2
using computers helps save forests
treating sewage water conserves freshwater aquifers
Explanation:
walking reduces CO2 by not using a car train or bus that puts out CO2
computers for note taking saves forests by reducing the amount of paper we use, therefore cutting down less trees to make the paper
treating sewage water and reusing it in factories conserves freshwater aquifers because we're recycling used water rather than continuing to use more and more freshwater.
Answer:
Walk or use a bicycle for short-distance travel ; reducing CO^2 emissions that contribute to climate change
Use computers for communication and taking notes ; saving forests
Treat sewage water and use it in factories ; conserving freshwater aquifers

How are many unicelled organisms. In addition , anything less than a cell is not alive. What do these statements imply about cells?
Answer:
The correct answer is - cells are the basic unit of life.
Explanation:
As it is given and also known that there are many unicellular organisms exists and they do not require the multicellular body to live their life or survival. Multicellular organisms are made up of various cells joined together to form a complex organization.
Anything less than a cell can not live or survive and also do not called a living entity. So, from above we can say the basic unit of the life is cell.
Definition of Salt Water
(Impact on Weather)
The thickness of seawater is an element of saltiness and temperature, Lagerloef clarified. Saltier water is heavier and will sink further in the sea, where it joins flows that course water all throughout the planet. ... Stable salt densities in the seas keep the world's environment in balance, researchers accept.
hope this helps:)
Answer:
Salt weathering or Salt Weather is a form of mechanical or physical weathering of rock. ... The salt derives from an external source (capillary rising ground water, eolian origin, sea water along rocky coasts, atmospheric pollution). Salt weathering is favoured by dry conditions, such as are found in warm and cold (arctic) arid climates.

4. The human population has experienced unchecked growth for the past 200 years. What does "unchecked" mean? A. Slow b. At a steady rate c. Unrestrained d. Dangerous
Answer:
B
Explanation:
The correct option would be B
The human population experiencing unchecked growth for the past 200 years does not mean that there were no restraining factors that limit the population. Factors such as death, competition for resources, diseases, etc., were still present.
Despite the limiting factors, the population has been growing. Hence, the correct word to replace 'unchecked growth' would be 'at a steady rate'.
Slow and dangerous really have nothing synonymous with unchecked growth.
The correct option is, therefore, B.
