First thing is we must be informed of what is replication all about. DNA is a molecule and like a codes for the genetic processes. And even during the replication process, RNA is not needed in this process. the RnA has all the information on how to create a code for the protein.
Plants!
Biotic factors are all of the living organisms within an ecosystem. These may be plants, animals, fungi, and any other living things.
Answer:
A. Erosion
Explanation:
A metamorphic rock takes a long time to form because of its shape and form. Therefore, the answer would be erosion.
Answer:
The correct answer would be zero.
Water potential measures the tendency of water to move from one area to another.
It is denoted by the symbol ψ.
It is determined by two main factors:
Solute potential (ψs): It is determined by solute concentration.
Pressure potential (ψp): The pressure exerted on a solution. It can be negative or positive.
ψ = ψs + ψp
Thus, in an open container, the water potential of pure water would be zero as pure water does not contain any solute (that is, ψs = 0) and pressure potential is zero (ψp = 0) in an open container.
The correct answer is PET requires a radioactive tracer.
In actuality, PET has a higher signal-to-noise ratio (SNR) than fMRI for a single scan. However, because there is no radiation exposure, fMRI generally produces a crisper image and can be done numerous times. Indeed, this may be a sufficient explanation for the shift toward fMRI from PET, which has been on the decline.
[15O] The use of H2O PET in brain activation research has long since been discontinued. There is no radiation exposure, and functional magnetic resonance imaging (fMRI) with blood oxygen level-dependent (BOLD) has a superior spatial and temporal resolution to PET.
