Answer:
Ribosomes are present attached to the rough ER:
1. To easily make proteins that are required inside and outside of a cell.
2. To take up amino acids easily.
3. To make it easier for the mRNA to travel from the nucleus to the ribosomes.
Explanation:
Ribosomes are involved in the synthesis of proteins. The rough endoplasmic reticulum is attached to the nuclear envelope. Hence, this provides an easy pathway for molecules to travel between the nucleus, rough ER and endoplasmic reticulum.
During the formation of a protein, mRNA is formed and the mRNA travels to the ribosomes through the rough ER. The location of the ribosomes makes it easy to take mRNA from the nucleus and amino acids from the cytoplasm and make proteins. When a protein is made, it can be used inside the cell or can be transported to the Golgi apparatus etc.
The reactants (inputs) in aerobic cellular respiration are:
glucose, oxygen
Answer: The eastern population of mice will most likely to change their behavior and become diurnal ( perform most of their activity during day time).
As per the question, due to geographical isolation mice population becomes separated as eastern and western population. Eastern population is inhabited by owls that hunt at night.
Owls capture mice when they go out in search of food during night time. Over a period of time, mice most likely to change their behavior and become active during day time.
This prevents them from being captured by their predator during night time.
Sodium ions are outside, while potassium ions are inside the neuron.
