Answer:
D. 1 BB : 2 Bb : 1 bb
Explanation:
This question involves a single gene coding for fur color in guinea pig. Black fur (B) is dominant over white fur (b). This means that, as stated in the question, if a black fur parent (BB) is crossed with a white fur parent (bb), a 100% heterozygous offspring (Bb) with black fur will result.
If two heterozygous guinea pigs are crossed i.e. Bb × Bb, the following gametes will be produced by each heterozygous parent:
Bb = B and b
Using these gametes in a punnet square (see attached image), offsprings with the following genotypic ratio will be produced:
1 BB : 2 Bb : 1 bb
BB and Bb = black fur guinea pigs
bb = white fur guinea pigs
Answer:
The eukaryotes, bacteria, and archaea that live in and on the human body are called normal microbiota. When they were originally discovered, scientists thought that the relationship between these organisms was parasitic because they thought that the organisms benefit from living on the host but did not help the host. In recent years, researchers have determined that most of our resident microbes derive and give benefit to the host. This makes the relationship between host and microbe one of mutualism. Pathogenic, on the other hand, are microbes that cause diseases.
The name of the locatuon is called an active site.
Answer: EDG
Explanation:
First, effortful processing is encoding that requires attention and conscious effort. This would be something like studying where you store facts in your mind for use later. Automatic processing on the other hand, is unconscious encoding of incidental information and of well-learned information. For example, I know what someone means immediately if they say it's noon. As for chunking, it is organizing items into familiar, manageable units. One perfect example would be my phone number. There are many different numbers, but its easier to manage when some are grouped together. Then there are mnemonics which are memory aids, especially those techniques that use vivid imagery and organizational devices. For example, I use the first letter technique (PEMDAS) to help me when solving math problems. Spaced or distributed practice is studying or processing with breaks to help understand concepts. For example, when I study, I take a five minute break every 20 minutes to help my brain cool down and be ready to learn more. Now, deep processing involves elaboration rehearsal which involves a more meaningful analysis. For example, giving meaning to different words or images and making them relatable.
