Restriction enzymes are DNA cutting enzymes found within bacteria. They can cut the DNA molecule.
Answer:
Feedback models are tools that provides specific, concise, and clear feedback for a particular thing.
Explanation:
Feedback models are tools that provides specific, concise, and clear feedback for the organization so that an organization can make useful changes which is necessary for the organization growth and development. There is high need of this feedback model which helps us to know about the specific areas where one needs to improve performances in order to work more effectively.
A.
The aim of a tax on a valuable resource, in this case residential water use, is to reduce wasteful practices. In this case the county is considering a special tax when residential water use is ABOVE a certain amount. This is an effective mechanism to reduce wastage by causing high users to incur more cost. Everyone will still pay for their water consumption in the normal way (typically by a $/unit cost), however the tax will take effect when the residential water consumption reaches a certain point. This penalises high users of water by forcing them to pay more for a valuable resource. Note that essential services like energy and water are often subsidised in society. This means that we do not pay the true cost associated with the use of the resource. Setting a tax that applies to those that consume over a certain threshold helps to reduce wastage of an undervalued essential resource such as water or energy.
Answer:
The two structures used in membrane transport are 1 integral membrane protein 2 peripheral membrane protein.
Explanation:
The various protein present in the plasma membrane help the later to exhibit its function to transport various solute molecules and ions across the membrane.
Integral membrane protein such as Na+K+ATPase helps in the transport of Na+ ions inside the cell and K+ ions outside the cell against their concentration gradient.
Peripheral membrane proteins are present in water soluble region of either extracellular region or cytoplasmic region or both.Peripheral protein also helps in the transportation of various solute molecules .
Answer:
Drooping the sticks on the table and transcribing the letters on the sides facing up follow Mendel's law of segregation by showing the segregation determining which alleles end up in the gamete.
Explanation:
- The Mendel's law of segregation states that the allele pairs always separate and segregate at gamete formation process and they randomly unite at the fertilization.
- When fertilization process is carried, the new organism developed has multiple factors for each trait, one from each parent.
- So the bending or drooping of the sticks and transcribing letter follows that law proposed by Mendel in 1860s.
- This law is also commonly known as the purity of gametes.
