Answer:
Due to their sizes.
Explanation:
Some materials diffuse through a semipermeable membrane because of their small size which can pass through small pores present in the semipermeable membrane of the cell while on the other hand, some molecules can't diffuse through semipermeable membrane of the cell due to its large size. Glucose, oxygen and sodium are the examples which are smaller in size and can diffuse through semipermeable membrane whereas fats, carbohydrates and proteins are big in size so it can diffuse through semipermeable membrane of the cell.
Answer:
a. As CO2 increases, the temperature also increases.
Explanation:
Carbon dioxide (CO2) is an atmospheric molecule produced naturally via respiration or artificially via burning of fossil fuels. CO2, as rightly stated in this question, has been referred to as a greenhouse gas because it acts to trap the sun’s heat on Earth.
Logically, an increase in the amount of greenhouse gas like CO2 released into the atmosphere means an increase in the greenhouse effect or global warming (increase in global air temperature). However, according to the GRAPHICAL REPRESENTATION in this question, an increase in the ppm concentration of CO2 led to an increase in the temperature (°F) of the globe over the years.
As depicted on the graph, at a CO2 concentration of 390ppm, the relative temperature was at over 1°F.
Answer:
FALSE
Explanation:
because birds doesn't chew their food because they doesn't have teeth therefore the seed remains in one piece and they still can germinate.
