The answer is; B
If we assume that the allele for black fur is B and that for white fur is b, crossing a homozygous black rabbit with a heterozygous black rabbit, will yield the following results (indicated in the punnet square below);
Genotypically, 50% of the population will be homozygous dominant, while 50% will be heterozygous. However, phenotypically, all offspring will bear black fur because the black fur allele is dominant over the grey allele.
Answer:
The insect pictured is in the order coleoptera
Answer:
The correct answer is: upper esophageal sphincter.
Explanation:
The alimentary canal is a very long tract responsible for the digestion of the food. It is composed of several organs with many different and important functions. The alimentary canal also has a few sphincters, which are muscular valves that open and close when needed for the food to pass or be retained.
The first sphincter is the upper esophageal sphincter. One particularity of this sphincter is that is one of the few sphincters in the body that opens and closes under our conscious control, which happens when we decide to swallow our food.
From the first to the last, the order of the sphincters in the gastrointestinal tract is: upper esophageal sphincter, lower esophageal sphincter or gastroesophageal sphincter, pyloric sphincter, ileocecal sphincter, and anus.
The correct answer is - C. genus and species.
The final scientific name of an animal represents two things, its genus, and its species.
The first name is the genus of the animal, in this case we have Canus. The second name is the species of the animal, in this case nipponicus.
All living organisms are classified in a same manner: kingdom, phylum, class, order, family, genus, species.
Since the name Canus reminds me a lot of Canis, I will take the wolf as an example:
Kingdom: Animalia
Phylum: Chordata
Class: Mammalia
Order: Carnivora
Family: Canidae
Genus: Canis
Species: C. Lupus
