How can biologic weathering result in chemical erosion? plants transpire water vapor
bacteria release acids and other agents that break down rock
large herds trample rocks and break up soil
roots loosen soil and break rocks

bacteria release acids and other agents that break down rock

Explanation:

One of the ways in which biological weathering results in chemical erosions is through bacteria releasing acids and other agents to break down a rock.

Weathering is defined as the physical disintegration and chemical decomposition of rocks to form sediments and soils.

The process of erosion removes the weathered materials from the earth surface.

Chemical weathering involves the decay of rocks by chemical means.

The bacteria is a biological organismAs it releases its acids and the rocks begin to break down, biological weathering takes places

For cyclohexane compounds drawn in a chair conformation:   -axial bonds are vertical  -equatorial bonds are parallel to two bonds within the ring.  thus, as i assume the chair conformation is drawn:   -the x group is in an axial position, as are the five other vertical bonds.  -three axial bonds are on the top face of the ring  -the other three axial bonds are on the bottom face  the position of the second substituent on each ring carbon is equatorial.  gauche groups must be on an adjacent carbon such as carbon 6 and carbon 2, and also gauche groups are rotated by 60 degrees relative to each other.  drawing the newman projections for c1–c2 and c1–c6 aids in visualizing the groups that are gauche to the y group on c1.  click this link and watch some academic videos that may you more understand the topic
