Answer:
The ratio is 6 to 1
Explanation:
1. a 6 sided cube of 1 mM has a volume of L * W* H (1*1*1=1) 1 mM.
2. a 6 sided cube has a surface area of one face surface area times 6 or (L * W) * 6 = 1mM * 1 mM * 6 = 6
so the ratio of surface to volume is 6/1.
From 2007 to 2010, the mink population stayed fairly consistent, but in 2010, the population dramatically decreased. Which of the following could describe what happened to the population of minks?
The mink population ran out of space to live so many died
A catastrophic event occurred like a disease or big natural disaster that quickly wiped out a large number of mink.
There were more voles for the mink to eat, so their population increased
The bears began to eat the mink in 2010 so the population of minks decreased.
The most likely event that led to a sudden decrease in the population of mink in 2010 would be a catastrophic event. The correct option would be B.
Decrease in populationA sudden and sharp decrease in the population of an organism can be caused by a host of factors. These include:
catastrophic events such as disease outbreaks, natural disasters, famine, etc. a sudden appearance of predators in the environmentIf the predator has always been in the environment with the population of the organism, this will not result in a sharp decline in the population. A population of predators suddenly joining the environment may be the only cause for a sharp decline in the population of the organism.

How does a nerve
impulse begin in a
neuron?
A. A positive charge is created in the cell that travels
down it.
B. The cell filling with sugars gives it an energy surge.
C. Water moves down the cell by osmosis.
D. The cell contracts like a muscle and connects to the
other neurons. i
A positive charge is created in the cell that travels down it does a nerve
impulse begin in a neuron. Thus, the correct option is A.
How the neuron get stimulus?When a neuron receives a chemical stimulation, a nerve impulse is formed. The electrical action potential of the nerve impulse passes along the axon membrane to the axon terminal. Neurotransmitters are released at the axon terminal, which transfer the nerve impulse to the next cell.
The resting potential of a neuron is the electrical differential across its membrane. The sodium-potassium pump, a transport protein, creates the resting potential. This protein generates a positive charge by moving a high number of sodium ions (Na+) outside the cell.

I believe that you are overthinking this. White light is a combination of all the colors on the visible spectrum. This means that if you shine a white light through a red filter, it will only show the red light that is in the white light. There will be only red because the other colors of the spectrum are not visible due to the filter.

Blood pumps through arteries due to contraction of the arterial walls but flows more freely through veins because there is little to no contraction. Based on this information, which would you expect to be present in higher quantities in arteries than in veins
Excitable cells like those found in muscle tissue are expected to be present in higher quantities in arteries than in veins.
What are Excitable cells?Excitable cells are defined as those cells that are capable of generating electrical impulses when stimulated. Example of such cells include:
Neurons,muscle cells( smooth, skeletal and cardiac)Endocrine cells.The artery is made up of higher amount of smooth muscles than the veins therefore, excitable cells like those found in muscle tissue are expected to be present in higher quantities in arteries than in veins.

By the end of the first week following conception, the fertilized egg now has approximately 100 cells and is known as the blastocyst.
What is cell?
Cell is defined as the base of life as it is the structural as well as functional unit of life. Cell is made up of pre existing cells and the cell contain various cell organelles such as mitochondria, endoplasmic reticulum, ribosomes, golgi appratus, nucleus, and cytoplasm.
Basically, cell is of two type one in prokaryotic and another one is eukaryotic. The prokaryotic cell is known as pre mature cells as they do not contain cell organelles and eukaryotic cell are known as advanced and developed cells as they contain several cell organelles.
The unicellular animals are made up of single cell and all the functions carried out in a single cell like amoeba and multicellular organisms are made up of multiple cells and there is specific cell for specific functions.
