If you experimentally increase the concentration of Na outside a cell while maintaining other ion concentrations as they were, what would happen to the cell's membrane potential
Given what we know about membrane polarization, we can confirm that If you experimentally increase the concentration of Na outside a cell while maintaining other ion concentrations as they were, the cells membrane potential would increase and be positively charged.
Increasing the concentration of Na outside a cell would cause there to be an increase and a build-up of positive charges outside of the cell. Due to the fact that the ion concentrations inside the cell remain constant, we can confirm that there will be a net positive charge on the outside of the cell and this will cause an increase in the membrane's potential.

Which structure determines what molecules can enter and leave the cell?
(a) the plasma membrane
(b) the cell wall
(c) the nucleus
(d) all of the above
Answer:
(a) the plasma membrane
Explanation:
also called as the cell membrane
The structure that determines what molecules can enter and leave the cell is the plasma membrane. The correct answer is option a.
The plasma membrane is a selectively permeable membrane that regulates the movement of substances in and out of the cell.
It is composed of a phospholipid bilayer with embedded proteins and other molecules that help to control the flow of molecules across the membrane. It is responsible for maintaining the internal environment of the cell and for allowing the cell to interact with its external environment.
Therefore, the plasma membrane is the structure that determines what molecules can enter and leave the cell. Option a is the correct answer.

if a dog has 78 chromosomes in each of his cells, how many molecules of dna does he have in each of his cells
If a dog has 78 chromosomes in each of his cells, each set of DNA has two sets of chromosomes because dogs are a diploid species so it would be 78/2 and in each cell a dog with 78 chromosomes would have 39 molecules of DNA in each of his cells.
What is the final product of meiosis?
The final products of meiosis in males is four sperm cells and in females it is one ovum and three polar bodies. Thus, the final product of meiosis is four sperm cell in male and one ovum in female with three polar bodies. The main objective of meiosis is to produce gametes, the sperm and eggs, with half of the genetic character of the parent cell.
Meiosis has been defined as the process in which a single cell divides into two identical daughter cells and the process is known as cell division. Meiosis has a type of cell division in sexually reproducing organisms that reduces the number of chromosomes in gametes.
The main functions of meiosis are mentioned below:
1) Meiosis in humans causes the decrease or reduction of the number of chromosomes in normal cells which is specifies as production of gametes.
2) meiosis induces genetic variation by the process of recombination.
Therefore, If a dog has 78 chromosomes in each of his cells, each set of DNA has two sets of chromosomes because dogs are a diploid species so it would be 78/2 and in each cell a dog with 78 chromosomes would have 39 molecules of DNA in each of his cells.

Explanation:
NLS, or the "oN-Line System", was a revolutionary computer collaboration system developed in the 1960s. Designed by Douglas Engelbart and implemented by researchers at the Augmentation Research Center (ARC) at the Stanford Research Institute (SRI), the NLS system was the first to employ the practical use of hypertext links, the mouse, raster-scan video monitors, information organized by relevance, screen windowing, presentation programs, and other modern computing concepts. It was funded by ARPA (the predecessor to Defense Advanced Research Projects Agency), NASA, and the US Air Force
Based on the trends shown in the table, in which of the following years was the owl population at carrying capacity?.
From the table shown, in 2015, the population reaches its carrying capacity.
The term carrying capacity refers to the maximum population that a particular environment can support. It is the average population size in a habitat. Beyond the carry capacity, the habitat can no longer support living things.
Given the table, the carry capacity is achieved when the birth rate is almost equal to the death rate. That occurs in 2015. Hence, in 2015, the population reaches its carrying capacity.

Sea turtles can be found all around the world. The habitats can range from the cold waters off California to the warm beaches of the Coral Triangle. The males of this population never leave the ocean, while the female sea turtle will come ashore to lay the eggs on the sandy beaches during the nesting season to hatch the eggs and produce the new organisms.
Therefore, the correct option is A.
