Ribosomes<span> consist of two </span>major components<span>: the small </span>ribosomal<span> subunits, which reads the rna , and the large subunits, which joins amino acids to form a polypeptide chain. Each subunit is composed of one or more </span>ribosomal<span> rna ( molecules and a variety of </span>ribosomal<span> proteins .HOPE THis helps! :)

Global warming occurs because of mainly, the pollutants that has been release out and made by the humans. In the choices above, the correct answer that will best suit in helping reduce global warming is letter b, reducing our fossil fuel use. It is because a fossil fuel contributes to global warming because it is a pollutant and harmful substance.
A. by building highways, railways, and airports
C.by providing power and Internet connections
D.by importing or developing innovative technologies
Physical capital applies to circumstances of production that subsist in a material way and could participate in the improvement of the effectiveness of commercial operation which is conducted out by the nation. Although the development of substantial training and the enhancement of food nutrition could be deemed as an expenditure, However, it does not directly involve in the expansion of the physical capital.
Answer:
sympatric
Explanation:
Speciation is the process by which new species originate and there are several mechanisms and processes by which speciation can take place.
When speciation occurs in a common geographical area where there are no barriers preventing the mating of species and the members of the species lie in close proximity to one another however, even in such conditions new species arise because of some differential characteristics. Such a speciation is termed as sympatric speciation.
In the given situation, the individuals that undergo genetic doubling get reproductively isolated from the original population because of incompatibility to mate even though they have close proximity with each other.
Therefore, the new species of evening primrose have arisen due to sympatric speciation.
Answer:
Scientists argue, re-examine, and consider new explanations to new data
Explanation:
Theories are susceptible to changes and new data can be incorporated into the theory because advances and discoveries are made.Scientific theories are testable and make falsifiable predictions thus, scientists argue, re-examine, and consider new explanations to new data.As additional scientific evidence is gathered, a new scientific theory may be modified and ultimately rejected if it cannot be made to fit the new findings.
Although theories are only modified in most cases, when a theory lacks any of the following characteristic they are susceptible to rejection by the scientists. A theory must be observable and repeatable to avoid frauds. Theories should be testeable and make falsifiable predictions with consistent accuracy across a broad area of scientific inquiry. It should also be well-supported by many independent strands of evidence. In addition, having consistency with preexisting experimental results and accuracy in its predictions as in any preexisting theories. All the above features provide room for change in theories over-time.
