Answer: 1. particles vibrate
more
2. individual particles do not
get ( change their temperature).
3. They vibrate less and become
motionless
Explanation:
when the tray is placed in the oven,the particles get heated ( this results in a change in temperature.) as the temperature increases so does their kinetic energy. What this simply implies is that the particles would tend to vibrate more vigorously than before.
When you remove the tray from the oven it’s temperature decreases, so also is it’s kinetic energy. This makes the particles to vibrate slowly and become motionless.
There are basically two main types of cells: prokaryotic and eukaryotic. The former is simple and while the latter is a complex type. So, the correct cell type for each description below are as follows.
no distinct nucleus: prokaryotic
can only be single-celled: prokaryotic
can either be single- or multi-celled: eukaryotic
Allopatric Speciation
describes why similar organisms do not interbreed because of a physical barrier.
Explanation:
The specific situation in which the population of identical species doesn’t interbreed or leaves in isolation with each other is referred as ‘allopatric speciation’. It is also considered a specification of geographical factors.
The factors that work as a barrier to the process of breeding between same groups of organisms are- mountain formation, formation of water bodies, agriculture etc. These natural and human occurrences affect the geography of a place that influences the separation in species.
Answer:
i know prokaryotic cells don't have a nucleus and eukaryotic cells do have nucleus.
