Answer:

"Rainwater pouring from an eroded bank into a river" is a non-point source of water pollution.

Explanation:

Bank erosion is the washing away of stream or river banks. This is distinct from erosion of the watercourse bed, known as scour. These erosion undermines the roots of trees which develop by a lake. As the roots closely connect the soil, they form abutments that jut out above the surface.

Non-point source water contamination is induced by widespread and isolated waste sources such as rain and snowmelt runoff, spills, leaks, and sediment erosions. To release any pollutant, without a permit, from a point source into navigable waters is illegal according to the Clean Water Act.

Answer:D. tapeworms live inside a goats body in a close relationship the goat.

Explanation:

In parasitic relationships,the parasite lives on the host and benefits from the host while causing harm to the host .the host does not benefit.the parasites are usually in close relationship with their host as their food source are substances of the host organisms.

The parasite may live in the host , these are called Endo-parasites.

The parasite may live outside the host, these are called ecto-parasite. In this example, the tapeworm is an endo-parasite that lives in the digestive tract of the goat. It absorbs digested food in the intestine through it's body surface.

In predator and prey relationship, the predator usually has to hunt for the prey and feed on it. It may kill it first or may not

You are a dog breeder and are interested in two traits that you believe are inherited by simple genetic loci glossy (G) coat is

Paul [167]

Answer:

GL, Gl, gL, and gl

Explanation:

The mom is glossy long haired. Since glossy (G) is dominant over to dull (g) and long hair (L) is dominant to short hair (l), the possible genotypes of the mom would be:

GGLL, GgLL, GGLl, or GgLl

The dad is dull and short haired, the genotype would be ggll.

GGLL x ggll

Progeny = all GgLl (all glossy long haired)

GgLL x ggll

Progeny = 8 GgLl, 8 ggLi (glossy long haired and dull long haired)

GGLl x ggll

Progeny = 8 GgLl, 8 Ggll (glossy long haired and glossy short haired)

GgLl x ggll

Progeny = 4 GgLl, 4 Ggll, 4 ggLl, 4 ggll (glossy long, glossy short, dull long, and dull short)

Only a cross of ggll with GgLl produced the offspring that cover the phenotypic range shown in the illustration. Hence, the genotype of the mom is GgLl.

The parental gametes produced by the mom would be; GL, Gl, gL, and gl
