The plasma membrane maintains homeostasis in the cell by keeping cell contents in and foreign material out, and by providing controlled avenues for the transportation of fuel, fluids and waste.
There are multiple reasons. 1) there are similar fossils found on different continents. 2) the continents shapes show that they could easily fit together. 3) there are similar rocks, minerals,and land forms on different continents. 4) there's evidence that there was once lush vegetation in areas with extreme cold.
Answer:
The correct answer is option d. "a and b".
Explanation:
Plenty of methods had been developed to estimate the body size of dinosaurs such as the gigantic Sauropods. One of the first estimations that paleontologists used was the Archimedes principle, consisting in dunking the entire skeleton of a Sauropod into a pool of water and measure the water displacement or more precisely small dinosaur models. However this method requires the preservation of almost the entire skeleton. A more used and useful method is to measure the length of the legs from the hip to the foot and using a 2/3's power relationship convert that to a mass. This method is more used since it only requires a couple of leg bones, which are often well preserved.
Answer:
There are many things that can be considered as a limiting factor such as water supply, competition, habitat space et cetera.
These factors affects the carrying capacity of the given environment. The human beings, animals uses food, space and water as their basic need.
These can affect the population of the organism if any of given components are presented in a limited amount.
The example of limiting factor that is human being to control the carrying capacity is food, space and water.
Answer:
The pH of a solution containing 0.1 mM H+ is 4
Explanation:
The pH of any solution is given by the following mathematical equation -
![pH = -log[H_{+}]\\](https://tex.z-dn.net/?f=pH%20%3D%20-log%5BH_%7B%2B%7D%5D%5C%5C)
----------- Equation (A)
Where,
= the concentration of hydrogen ion in the solution.
Given
= 
Substituting the given value in equation (A) , we get -
![pH = -log[10^{-4}]](https://tex.z-dn.net/?f=pH%20%3D%20-log%5B10%5E%7B-4%7D%5D)
Hence, The pH of a solution containing 0.1 mM H+ is 4
