Masja [62]

When talking about evolution, a good example is bacterial resistance to antibiotics.

We start with a bacteria colony, and in contact with antibiotics, most of them die.

Some of them in the colony do not die and took that antibiotic to create a mutation of its DNA to be resistance to that.

They evolved  survive that antibiotic.

Define the five systems. Be sure to include enough information to distinguish each system from the others. (Site 1)
VladimirAG [237]
By definition, a body system is primarily comprised of different organs and tissues that work one another to achieve a common body process. These body systems would include:

Circulatory system - concerns with the circulation of blood
Digestive system - breaking down of food particles 
Skeletal system - composed of bone structures serving as our body's framework
Nervous system - composed of nerve cells that responds to different stimuli
Respiratory system - concerns of utilising the entry of oxygen and the exhalation of carbon dioxide.

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)

<em>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.</em>

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

If analogous structures are often examples of convergent evolution what types of structures would likely be examples of divergen
Vilka [71]
As there are no answer choices, I'm going to answer this just based off my knowledge

Analogous structures suggest convergent evolution because they have both evolved from a set of species but for different reasons and from different causes.
