Answer:
The suitable words for fill in the blanks will be -
- embryo
- flippers
- disappear
- off
- genetic
Explanation:
Examining a dolphin embryo highlights its evolutionary history. Early in dolphin development, both fore and hind limb buds form. While the forelimb buds continue to develop into flippers, the hind limb buds disappear. The genes that are normally active in the hind limb buds of four-limbed animals are turned off. A genetic change leading to the silencing of a trait during development may have been an important milestone in cetacean evolution.
Answer:
convention cells
Explanation:
In the field of fluid dynamics, a convection cell is the phenomenon that occurs when density differences exist within a body of liquid or gas. These density differences result in rising and/or falling currents, which are the key characteristics of a convection cell. When a volume of fluid is heated, it expands and becomes less dense and thus more buoyant than the surrounding fluid. The colder, denser part of the fluid descends to settle below the warmer, less-dense fluid, and this causes the warmer fluid to rise. Such movement is called convection, and the moving body of liquid is referred to as a convection cell. This particular type of convection, where a horizontal layer of fluid is heated from below, is known as Rayleigh–Bénard convection. Convection usually requires a gravitational field, but in microgravity experiments, thermal convection has been observed without gravitational effects.
Kinetic sand is what I would pick
Answer:
The correct answer will be virus.
Explanation:
The virus is the infectious agents which cannot replicate themselves. these viruses contain a protein capsid surrounding the genetic material.
The genetic material in the virus could be DNA or RNA but do not have both as single-stranded or double-stranded forms.
A virus with RNA are common in nature and an only a limited amount of RNA or DNA can fit a capsid and the capsid along with genetic material is known as the nucleocapsid.
Since the specimens show RNA but not DNA it is a virus-like Ebola, polio, measles, therefore, the specimen is virus and is the correct answer.
The enzyme inhibitor fits into the enzyme's active site, which prevents the enzyme from catalyzing the reaction.
