Arbitrary level refers to the fundamental vertical subdivision of an excavation square, implied only when easily identifiable natural strata are absent and when natural strata are more than ten centimeters thick.
Natural strata refer to a vertical subdivision of an excavation square, which is reliant on the natural breaks in the sediments in terms of grain size, color, hardness, texture, or other features.
It is important to know the difference between the arbitrary and natural levels as arbitrary levels could amalgamate artifacts from distinct natural levels, that is, of distinct geologic contexts.
The archaeologists can recover the smallest ecofacts and artifacts with the assistance of flotation, screening, and bulk matrix processing
Answer:
A <u><em>receptor</em></u> is a protein that recognizes and responds to a signal.
Explanation:
A receptor is a protein molecule present on the cells on which the signalling molecules can bind and generate a physiological response. Some receptor molecules can also respond to Sun and light. Each type of cell has specific receptors molecules and hence can respond to specific signals. The receptor molecules hence tend to receive signals for a cell. Molecules such as hormones bind to the receptors.
Most irregular galaxies are thought to have formed from <span>collisions between other galaxies.
This is just one wat that irregular galaxies are formed; the collision is due to the interaction of their gravitational forces. These galaxies might have been regular before the collision, but are not deformed.
Another form of irregular galaxies are the ones that are still very young and therefore have not yet reached their symmetrical state.</span>
First of all, the most common type of CNS neuron is the multipolar neuron meaning it has many dendrites and dendritic branches, a cell body or soma, and a single axon. The information flow through this neurons starting from receiving multiple impulses from multiple synapses since this kind of neurons has many dendrites. The signal will then flow in an anterograde manner meaning the multiple signals will flow towards the cell body or the soma to be integrated. Next is that the integrated signal will flow to the neuron's axon to be transmitted to other neurons.
Answer:
A. acquired traits can be passed to offspring.
Explanation:
Mendel tracked the segregation of parental genes and their appearance in the offspring as dominant or recessive traits.
