please this is my answer
building blocks of tissue for living things
<span>Diffusion. Diffusion is when particles in a highly concentrated area spread out to an area of lower concentration. The membranes of cells are very thin, which allows diffusion of different materials to happen easily.
During respiration, oxygen and glucose concentration in the cell is lower than in the surrounding blood. This causes oxygen and glucose to move into the cell via diffusion. Carbon dioxide is produced inside the cell and this makes the concentration of CO2 higher in the cell than in the blood, so the excess diffuses out of the cell.</span>
Answer:
- These are water bodies formed from melting glaciers
- However, their size can vary from a few square meters to thousands of square kilometers
- They can be seasonal, existing for a few months or exist for hundreds of years or more
Explanation:
The lakes and the ponds are freshwater bodies of water. They can be formed in numerous different ways, from melting of glaciers, rivers flowing into closed valleys, changes in the geography of a space, increased amounts of precipitation. They can vary in size, and there are ponds and lakes that are very small, just few square meters, or to be thousands of square kilometers in size. Some of the lakes and ponds tend to be seasonal, unlike the majority that are existing throughout the whole year, and the reasons for this are the climate and the manner in which they form. Some lakes can be very old, millions of years of age, like the Ohrid Lake in Macedonia, which is also the most important lake in the world from biogeographical stance of point, and it is considered as one of the most attractive ones in the world as well.
