In a feeding experiment, ducks are given their choice of white or wheat bread. which of these is a null hypothesis? select one: ducks do not like white or wheat bread. ducks have no preference for white or wheat bread. ducks do not eat wheat bread when white bread is available. ducks like white bread but not wheat bread. ducks prefer white bread.

Ducks have no preference for white or wheat bread

Explanation:

The null hypothesis is the statement of no change (default). It proposes no relationship between the variables of the phenomenon under investigation. This hypothesis is usually considered to be true until proven otherwise by the experiment. It is designated as H0 and, if proven wrong, the alternative hypothesis (HA), is adopted.

answer: tributaries flow into rivers.

wetland is a biome that develops when the water gets accumulated in a land exhibiting a huge depression. these form either seasonally or permanently. the water in the wetland comes from rivers, lakes, ocean, flood, rain or other sources. the wetlands includes mangroves, marshes and peatland.

tributaries flow into the rivers develops a wetland because such water will get deposited in the depression and will restrict the original flow of tributary water. hence, water with low drainage current combines with the river water.
