Answer:
Massive stars transform into supernovae, neutron stars and black holes while average stars like the sun, end life as a white dwarf surrounded by a disappearing planetary nebula. All-stars, irrespective of their size, follow the same 7 stage cycle, they start as a gas cloud and end as a star remnant.
Explanation:
The correct answer is C. The temperature of the water
Explanation:
In an experiment such as the one described about the speed of snails in water, the manipulated variable is the factor or element that is manipulated on purpose. This means the researcher or researchers slightly change this element to compare how this affects another variable. In this context, the manipulated variable is the temperature of the water because researchers used three different temperatures (cool, room-temperature, and warm), and therefore they manipulated or changed this factor. Moreover, it is expected temperature affects the distance nails move, which is the main variable.
RR x rr
or if you're using the letter "t" to represent the alleles TT x tt
Homozygous means that a particular gene has identical alleles on both chromosomes. TT is for a dominant (stronger) trait and tt is for a recessive (weaker) trait.
Hope this helps! :)
