Answer:
Given that a negatively charged rod is brought closer to two metal spheres which are in contact with each other as shown: So, free electrons from rod will be attracted towards the metal spheres.
Answer:
Reproduction, growth and development, regulation, homeostasis, and energy processing.
Explanation:
Reproduction, growth and development, regulation, homeostasis, and energy processing are the traits or characteristics that are determined by the genotype. These traits are under the control of genes of an organisms and can be changed if the change in the genes occurs while on the other hand, the physical characteristics of an organisms are determined by phenotype means phenotype is responsible for the appearance of an organisms.
Answer:cell walls, cell membrane, mitochondria and nucleus

Explanation:
The average star cycle: nebula, protostar, main sequence, red giant, white dwarf. The massive star cycle: nebula, protostar, main sequence, super red giant, supernova, black hole, neutron star.
The star cycle is the sequence of changes that a star undergoes throughout its existence.
<h3>The evolutive stages of an<u>
average star</u> are </h3>
- Nebula: Stars are born from the nebula that is the dust and gas particles condensation due to gravity effect in the interstellar clouds
- Protostar: It is a more advanced level of condensation.
- Main sequence. Equilibrium between gravity and nuclear fusion helps the star keep stable as long as the fuel lasts. The two main types are
• <em>Orange dwarf</em><em>: </em>between the red dwarf and the yellow dwarf
• <em>Yellow dwarf:</em> Like the sun
- Subgiant: occurs when orange and yellow dwarfs finish their main sequence and start to run out of fuel, expanding.
- Red giant. After the subgiant stage, the star enters a giant phase. The star can reach a size of up to 100 times its current size.
- White dwarf. When average-sized stars run out of fuel, the red giant begins to disintegrate, losing its outer layers and exposing its core, which will become a white dwarf.
<h3>The evolutive stages of a<u> </u><u>
giant star</u><u> </u>are </h3>
- Main sequence. There are two main types
• <em>Yellow supergiant</em>. Extremely short phase. Almost no stars are known to be in this stage. The star swells on its way to becoming a red supergiant.
• <em>Red supergiants</em> are the largest stars in volume, but not in mass.
- Supernova. When fuel is over in the red supergiants, the gravitational collapse produces a violent explosion originating the supernova.
- Neutron star. A celestial body that remains as a remnant after the explosion gives rise to a supernova.
