From the anterior vena cava,blood flows to the right atrium.
Explanation:
humus is made of and dissolved organic matter + undissolved organic matter and microorganisms which can decompose it
<u>Calcium carbonate:</u>
The calcium carbonate is found in sea shells and the bones of sea creatures. And it is settled on layer of ocean. The pH level can be equilibrium with atmospheric 
. There is constant concentration of in the water.
The limestone and calcium carbonate is present in the rocks, streams, lakes is helps to maintain the constant pH in the minerals present in the rock react with excess acid in the water.
When the acids or bases react with the calcium carbonate ,there is the excess change in the pH. The mixture of calcium carbonate ions in the water to prevent the damage in acid rain.
Answer:
In biology, heterozygous means that the two alleles of a gene will be different. Homozygous means that the two alleles of a gene are similar.
A cross between to heterozygous parents for genes (Ww) is shown below:
W w
W WW Ww
w Ww ww
The results show that 25% of the population will be homozygous dominant, 50% of the population will be heterozygous dominant, 25% of the population will be recessive for the trait.
Answer:
Hi! so the answer is decomposition.
Explanation:
If you are looking at the graph and go to the carbon source labeled B and you look at the arrow to here soil organic matter points to you can see that it points to decomposition. Also because I took the test and got it correct. I hope you can mark me as brainleast. thank you :)
