Answer:
Oxygenated blood is blood that has been oxygenated, it has a large percent of oxygen.
Explanation:
Oxygenated blood is blood that has been oxygenated by the lungs, it then is pumped all over the body.
(oxygenated- enriched with oxygen)
Synonym: Oxygen rich blood
Answer: 1,3&4
Explanation:
The lac operon is induced by lactose in the absence of glucose, this is because when lactose is present in the medium, lactose binds to the repressor protein, one molecule on each subunit, causing a conformational change in the repressor.
The Repressor-lactose complex is in active, so the repressor does not bind to the operator site.
RNAP binds to the operator, identifies the promoter sequence and transcribe the structural genes.
RNAP can attach to the promoter site only when CAP doesn't bind the operator. In the absence of glucose in bacteria cAMP is available which combines with CAP, preventing CAP from binding the promoter site.
Answer: Options A,B,C, and F
A. Global climate changes.
B. Atmospheric changes.
C. Predator-prey relationships.
F. Radiation of numerous terrestrial groups.
Explanation:
Due to increasing natural disasters (such as volcanic eruption) and arthropological activities (such as mining) that led to the emission of harmful gases, changes in the atmosphere and overall climatic conditions is established.
They saturate the atmosphere and due to limited carbon sinks to absorb them, they alter the climatic parameters like temperature, rainfall, and relative humidity.
The effects of change in climatic parameters are flooding, habitat destruction, increased predation, and among others. Thus, leading to dispersal of some animal species and decline of many others.
Predator-prey relationship also plays an important role in the expansion (likely through migrating from danger) and in most cases decline of some animal species, especially when there's limited prey species to go round for the predators.
The information collected from observations by scientists is primary data
The answer to this question is what we called the Embryonic connective tissue. An embryonic connective has two types which is known as mucous connective tissue that is functions to resist compression which is found in the umbilical cord and the Mesenchyme that functions as the primitive connective tissue that is composed of collagen fibers.
