Identify the importance of water. check all that apply.

1. it ensures life on earth can exist.

2. it is a part of all organic compounds.

3.it is used by plants for photosynthesis.

4. it is the main component of many biological components, including blood.

Option 1, 3 and 4

Explanation:

Most of the natural processes on earth involves the usage of water such as hydro-logical cycle, nutrient cycle, climate cycle etc. All these processes are very essential for the survival of life on earth and thus,  option A is correct

In phosysthesis , H+ ion and oxygen comes from the dissociation of H2O. while oxygen is released into the atmosphere, H+ get associated to form energy molecule like NADH etc. Thus,  option 3 is also correct

Blood contains 92% of water and thus it forms the main component of biological components. Thus,  option 4 is also correct

But as given in option 2 , all organic compounds have water only in there aqueous phase (solution). Therefore , option 2 is in correct

gregor john mendel is known for study of inheritance in pea plants. he used garden pea plant for his study, having alternative traits for various characters. he performed cross-breeding in pea plants to check how characters are transmitted between parents to offspring, such as cross between pure tall and pure dwarf plant. mendel studied the inheritance patterns in pea plants for various generations.

thus, the correct answer includes options and f).
