State three factors that influence the movement of molecules though membrane.
Answer:
Thickness of membraneTemperature and pressure Concentration gradientwhat is biological classification? explain it
Answer:
Biological classification is the process by which scientists group living organisms. Organisms are classified based on how similar they are. Historically, similarity was determined by examining the physical characteristics of an organism but modern classification uses a variety of techniques including genetic analysis.

A scientist is studying the population of a particular species of beetle in an ecosystem. The beetles currently have an estimated population of 11,500 individuals on a wildlife preserve of 115 hectares. (One hectare is equal to 2.47 acres of land.) The scientist calculates the carrying capacity at 14,600 individuals.
PART B
What will likely happen to the population of these beetles during the next year if the resource level stays the same? Explain your answer.
PART C
These beetles have a uniform distribution. In year 1, how many beetles are there per hectare? How many beetles per hectare were there in the year the beetles reached carrying capacity? Round up or down to the nearest whole number, if necessary.
PART D
During the year the beetles reached carrying capacity, a flood in the region decreased the population to about 77 beetles per hectare. What is the total estimated population of the beetles after this disaster? What percentage of the carrying capacity is the population now?
PART E
Over a period of time, the beetles once again reached carrying capacity and sustained it for many years. However, pollution from a nearby factory leaked into the ecosystem, making 55 hectares of the land uninhabitable to the beetles. Predict how the estimated carrying capacity will change and explain your reasoning for your estimation.

To create a molecular model a student will use blue spheres to represent nitrogen (N) and white spheres to represent hydrogen (H). which option correctly describes a model of ammonia, NH3?
A. three blue spheres and three white spheres
B. one blue sphere and three white spheres
C. three blue spheres and one white sphere
D. one blue sphere and one white sphere
A molecular model is a three dimensional representation of a molecule that aids conceptualization of the actual nature of the molecule.
The correct answer is option B: one blue sphere and three white spheres
A molecular model helps us to see something close to what a molecule actually looks like in a three dimensional way.
The essence of molecular models is to aid conceptualization of details about arrangement of atoms in a molecule.
Since nitrogen is represented with blue balls and hydrogen is represented with white balls, it follows that a properly prepared model consists of one blue sphere and three white spheres.

do you think your heart plays the biggest role in the process of getting your blood become rich in oxygen and transporting materials gases and other molecules to and from the different parts of the body?
WHY DO YOU THINK SO?
Yes. Absolutely. Without heart, no one can live. It helps in pumping of oxygen rich blood to all body cells and tissues. It also helps in transportation of various materials like potassium, sodium, calcium etc. in our body. The main function is that it helps in excretion of wastes.
Since blood is liquid and heart pumps it, the waste materials like CO2, gets diffused and becomes impure blood. Then it is taken to lungs for purification and again reused.
So, heart actually helps us indirectly in many ways.

25. How do the excretory systems of animals that secrete uric acid differ from those of animals that excrete urine?
34. Explain why maintaining water balance is part of the process of excreting nitrogenous wastes.
thanks!!
Answer:
25.Nitrogenous wastes in the body tend to form toxic ammonia, which must be excreted. Mammals such as humans excrete urea, while birds, reptiles, and some terrestrial invertebrates produce uric acid as waste. Uricothelic organisms tend to excrete uric acid waste in the form of a white paste or powder.
34.The excretory system removes cellular wastes and helps maintain the salt-water balance in an organism. In providing these functions, excretion contributes to the body's homeostasis, the maintenance of constancy of the internal environment. When cells break down proteins, they produce nitrogenous wastes, such as urea

Underground mining removes minerals from deep in the earth. Miners use blasting to separate the "waste" from the mineral deposit. Which statement best describes
an environmental consequence of this process?
O Underground mining activities often cause noise pollution
O Acid mine drainage kills plants and animals around the mine.
O High salinity of wastewater reduces soil fertility and vegetation
O Soil is removed by the force and pressure of the drilling process.
Answer:
Acid mine drainage kills plants and animals
Explanation:
took the quiz :)
The correct answer as to the environmental consequence of using blasting to separate wastes from mineral deposit is noise pollution. The statement that best describe the process, therefore, would be that underground mining activities often cause noise pollution.
Blasting simply means to break something apart or to blow up something. When blasting is associated with mining, it usually involves the use of explosives. These explosives make loud noise when they are used in blasting.
Hence, blasting can be said to be a source of noise pollution to those staying close to the mining area.
