Answer:
Decomposition is the process by which dead organic substances are broken down into simpler organic matter such as carbon dioxide , water and mineral salt
Answer:
Lack of moisture – Papery leaves on plants are often caused by leaf scorch. .
Excessive moisture – Leaf scorch can also be attributed to too much moisture. This occurs when the soil is so wet that the roots are deprived of oxygen. As the roots smother, the leaves turn dry and papery and the plant eventually dies.
Explanation:
The process that breaks down sugars to make ATP when oxygen is present is called Cellular Respiration. During this process the sugar is broken down to CO2 and Water which in the process ATP is made that can be used for cellular work.
Answer:
Gene for blood type O is recessive
Gene for blood type A and B is dominant
Gene for blood type AB is neither dominant nor recessive but a form of co-dominance
Explanation:
In the ABO blood group,
A and B are dominant genes, O is recessive genes.
So the different genotype and its corresponding phenotype is as follows –
Genotype Phenotype
AO A
BO B
AB AB
AA A
BB B
OO O
Hence, the two alleles AB occur and express together. Therefore, AB blood group is an example of co-dominance.
Blood type also varies with the presence of Rh factor. If Rh factor is present, the blood type will represented with a “+” symbol. And if Rh factor is absent, the blood type will be represented by “-“symbol.
Answer:
Instable behavior.
Explanation:
The checkpoints currently behaving instable in sally cancer cells because mutants show genetic instability so this instability is the cause of cancer disease. Two checkpoints are sensitive to DNA damage, one occur before mitosis cell division and the other occur before replication of DNA. So damage occur in these two check points leads to instable behavior of cancer cells.
