Which type of mutation occurs in reproductive cells and can be passed to offspring: ? a. somatic mutationb. germline mutationc. point mutationd. frameshift mutation

The answer is B. germline mutation. 

The germline mutation is heritable variation in the lineage of reproductive (germ) cells. Germ cells are cells that give rise to the gametes, so a mutation in germ cell will be seen in a sperm cell or egg cell but not in a skin cell, for example.

The point mutation is the changes in a single nucleotide base on the DNA molecule.

Frameshift mutation, due to addition or deletion of a base, results in the change of reading frame and totally different translation

Somatic mutation is mutation in a somatic cells and is not passed on to the next generation. 

1: most common garden plants prefer loam — soils with a balance of different-sized mineral particles (approximately 40% sand, 40% silt, and 20% clay) with ample organic matter and pore space. however, some plants grow better in sandy soils, while others are well-adapted to clay soils.

2: available water capacity is the maximum amount of plant available water a soil can provide. it is an indicator of a soil's ability to retain water and make it sufficiently available for plant use. available water capacity is the water held in soil between its field capacity and permanent wilting point.

3: it is the same for all living things (plants and animals). it also includes very tiny organisms that our eyes cannot see. they are known as microorganisms, and include viruses, bacteria and fungi.
