Answer:
Messenger RNA is a type of RNA that is necessary for protein production. In cells, mRNA uses the information in genes to create a blueprint for making proteins. Once cells finish making a protein, they quickly break down the mRNA. mRNA from vaccines does not enter the nucleus and does not alter DNA.
So the answer will be C or A
Explanation:
Answer:
A) To make sure that the effect is not occuring through actions in the nervous system
Explanation:
In the above scenario, researchers actually studies the effect of hormone to the organ but they are in a situation to study the effect on organ are either hormone base or nervous system base (neurons). For this reason they will cut the neurons to study the effect of hormone on the organ.
So, to check the effect of hormone they should cut the neurons to make sure these effect are not due to actions of nervous system.
Answer:
True.
Birth control pills contain a combination of hormones that prevent the formation of the ovule, by prevent the formation of the luteinizing follicle. There are several types of birth control pills,but the process is generally the same
Explanation:
Answer:
Explanation:
Proteins and Nucleic Acids are not similar in structure. They look nothing alike, either as large molecules or in terms of their building blocks. While they're both made up of mostly carbon, hydrogen, nitrogen, and oxygen, the elements are assembled in vastly different ways. The major relationship between the two has to do with protein production -- DNA contains the information that a cell uses, with the help of RNA, to make protein.
The answer is Transportation systems can be conceptualized as a set of relationships between nodes, networks, and demand. These relationships include places that spatially express that demand, flows between them, and infrastructure designed to manage and connect those flows. All components of a transportation system are designed to facilitate the movement of passengers, cargo and information, either as separate components or together.
demand. A derived function for the mobility of people, cargo, and information for a variety of socioeconomic activities. Node. Where movements begin, end and pass through (mediation), entry or exit points in a transportation system. They vary according to the geographical scale considered, from local nodes (e.g. a subway station) to global nodes (e.g. port or airport terminals).
networks. Consisting of a set of links expressing the connectivity between places and the capacity to handle volumes of passengers or cargo.Locations. Nodes where demand is expressed as a point of origin, destination, or transit. The level of spatial accumulation of socioeconomic activities (production and consumption) collectively defines demand and where that demand is produced.
streams. The amount of traffic in a network made up of nodes and links. This is collectively a function of demand and the ability of chains to support it.
infrastructures. Means of transportation such as highways and terminals express the physical reality of a network and are designed to handle demand with specific characteristics in terms of volume and frequency. The facilities that provide access to a network are collectively characterized by their centrality and the links they emanate.
