You are examining the phylogenic relationship of a newly discovered plant species (Species 2). You amplify the RUBISCO barcode and sequence the DNA. After entering your sequence into BOLD the following comparison comes up.Species 1. ATGCAAATTTGGGCATCCGAATGGTTGCAASpecies 2. ATGCAAATTTTTTGGGCATCCGAATGGCAAWhat DNA modifications have occurred in Species 2 that makes it different from Species 1? Check all that apply.a. Inversionb. Duplicationc. Deletion
Inversion has the name suggest, has to do with a segment of DNA being reversed from end to end.
In this case here,
Inversion is taking place here.
species 1 ATGCAAATTTGGGCCCATGAATGGTTGCAA
species 2 ATGCAAAAATTTTGGTACGCCGAATGGTTGCAA
Therefore, the sequences in bold in species 1 are observed to be reversed end to end in species 2.
I am sure it's not feasible because deletion entails removal of a few sequences.
It can be seen that species 2 is longer than species 1, which gives another reason why deletion is not feasible too, as no sequences are seen to be deleted.
I believe duplication is feasible since AATT sequences are repeated once.
Our final answer,
inversion and duplication occur here.
How many different ways does/could energy change form during its travels between the Sun and your stomach?
Energy will take the path from sun to stomach as sun's energy to chemical energy followed by thermal and mechanical energy.
The energy of the sun is in the from of chemical energy which is the ultimate basis of life on earth . The process of photosynthesis occurs to form a chemical compound named glucose. The food ingested is in polymer complex forms as protein, carbohydrate, fats etc which is broken into monomers for absorption in intestine and stomach.
The dietary compound has energy stored in their bonds as chemical energy.
So, from sun human consume chemical energy which is stored in food.
The energy even if consumed by eating meat is also chemical energy which is stored as potential energy.
The breakdown of food or chemical energy into monomers leads to release of thermal energy or heat to maintain optimum body temperature.
Chemical energy also gets converted to mechanical energy which allows functioning of vital organs and movement of body.
Azotobacter A. forms endospores. B. forms cysts. C. fixes carbon dioxide. D. are used as an indicator of fecal pollution.
Answer: Azotobacter forms cysts. The answer is, “B.”
You want to make 50 ml of 1X tricaine solution in order to euthanize some fish. How much of a 20X tricaine stock solution will you need to dilute in order to make your solution?a. 1 ml b. 5 ml c. 0.4 ml d. 10 ml e. 2.5 ml
Answer: e. 2.5 ml
According to the dilution law,
= concentration of stock solution = 20X
= volume of stock solution = ?
= concentration of required solution= 1X
= volume of required solution= 50 ml
Thus 2.5 ml much of a 20X tricaine stock solution is needed to dilute in order to make your solution.
Which three organization levels are in a human stomach?Muti choice 1) cell 2)organ 3)organ system 4)organism 5)tissue
Cell, tissue, and organ.
A cell is an obvious one because it makes up the tissue, and it is needed in order to form an organ. Meaning tissue and cell would have to be included. Tissues witch are made of many cells form an organ, and an organ would be the human stomach/digestive system. It can't be organ system because a stomach can't be a whole system including the heart and ect. It can't be organism because a stomach isn't enough organ systems to create an organism.
Cell Organ System Organ
cells make up everything as a building block of life.
