Answer:
· As particles get smaller, their magnetic properties, particularly with regard to temperature, also diminish. However, several strains of bacteria produce magnetite – fine, uniform nanoparticles that have desirable magnetic properties. These magneto tactic bacteria use a protein to form crystalline particles about 50 nanometers in size.
Answer:
Black dogs = A_B_
Brown dogs = aaB_
Yellow dogs = A_bb and aabb
Explanation:
In laborador retrievers, pigment color is influenced by two genes. Gene A determines the type of pigment produced and gene B affects whether the pigment gets deposited in the hair shaft. If two heterozygous black laborator retrievers were crossed and offspring were produced in a ratio of 9 black dogs to 3 brown dogs to 4 yellow dogs, what are the genotypes of the offspring?
Gene A determines colored pigment.
Gene B ensures that the colored pigment is deposited.
Two heterozygous black laborador retrievers were crossed.
AaBb x AaBb
Progeny
9 A_B_
3 A_bb
3 aaB_
1 aabb
<em>Since there were 9 black, 3 brown and 4 yellow dogs, the possible genotype of the different colors are: </em>
Black dogs = A_B_
Brown dogs = aaB_
Yellow dogs = A_bb and aabb
Answer:
Mitosis occurs in Interphase and cytokinesis occurs in Anaphase
Explanation:
Answer: the tundra is important to protect is that it serves as a habitat for migratory populations, like waterfowl, shorebirds, caribou and several bear species. It is home to endangered animals such as the Arctic Fox, Polar Bear, Grizzly Bear, Caribou, and Musk Ox.
Explanation:
The correct answer is - hierarchical
Each entry in a(n) hierarchical database has one parent node, with the parent node having several child nodes.
A hierarchical database model is a data model where the data is organized into a tree like structure. The data is stored as records and these are connected to one another through links.
