By 1989 through captive breeding, the number rose to 120. What percent change is this
In 1987, the population of Black Footed Ferrets in the world was 18 individuals. By 1989 through captive breeding, the number rose to 120. percent change in this [(120-18)/2]/18.
Why did black-footed ferrets become extinct?
There may have been as numerous as 5 million black-footed ferrets in the United States in the earlier 1900s. while by the 1970s they were stressed to be expired as a result of habitat fragmentation and general prairie dog drops due to: Being slowly exterminated.
Thus, the number rose to 120. percent change in this [(120-18)/2]/18.

Gomphoses are fibrous joints whose bones are joined by fibrous tissue, ligaments, cords, or bands.
What is gomphosis?They are unions that are verified by multiple collagen fibers, which extend between the two joint surfaces and constitute the periodontium.
These joints without mobility, characterized by the presence of fibrous tissue, are the articulation of the dental roots with the alveolar cavity in which they are housed.

Assume that one of the disinfectant/antiseptics tested using the disc method had a clear zone of inhibition and to your surprise, you discover minute growth near the disc. What would explain this phenomenon
The presence of the minute growth near the disc signifies that the bacterial innoculum contains mutant microorganisms that are able to grow in the presence of toxic substances.
What are zones of inhibition?The sensitivity testing in a microbiology laboratory is done to determine the effect of antibiotics on various bacteria organisms
The zone of inhibition when a disk method is used signifies the area of media where bacteria are unable to grow, due to presence of a drug that impedes their growth.
If there are presence of minute growth near the disc, it means that the bacterial innoculum contains mutant microorganisms that are able to grow in the presence of toxic substances such as disinfectants.
If these mutant bacteria organisms are not cleared by the disk method, it means that they cannot be killed by the disinfectant/antiseptics that is being tested.

The drawings below represent two cell types from a rat. The adipocyte is a fat cell, and the astrocyte is part of the central nervous system.
(picture)
Which of the following best explains why the two rat cell types are different?
Choose 1 answer:
(Choice A)
Because the cells have undergone mitosis, the adipocyte and the astrocyte contain different genes.
(Choice B)
Because of differential gene expression, the adipocyte and the astrocyte produce different proteins.
(Choice C)
Because the cells are the result of a fertilization event, the adipocyte and the astrocyte contain different chromosomes.
The statement 'due to differential gene expression, the adipocyte and astrocyte produce different proteins' explains why the two rat cell types are different.
What is gene expression?Gene expression can be defined ad the differential process by which certain genes are transcribed in one cell type.
