Explanation:
Answer:
Mitosis, Meiosis, and both are written below
Explanation:
Mitosis: produces more somatic (body) cells, purpose is for healing and growing, the daughter cells are exact replicas
- This is because mitosis occurs in body cells and is used for growth, so all the daughter cells are the same.
Meiosis: results in sex cells (gametes), results in eggs and sperm, purpose is for creating new individuals (eventually), each daughter cell is different, has 2 separate division stages
- This is because meiosis occurs in gametes and is used in reproduction.
Both: Chromosomes need to replicate before the whole process begins, a form of reproduction
- This is because both are reproducing (they are dividing) and DNA must be replicated so each daughter cell has it.
Answer:
a closed circulatory system.
Explanation:
an earthworm circulates blood exclusively through vessels.
Answer:
Diffusion rate is 1.96 ×
/s
Explanation:
Diffusion is the process in which the molecules of a substance propagates from a region of higher concentration to region of lower concentration through a semi-permeable membrane.
diffusion rate = 
Given that; diameter = 15 mm, time = 15 minutes.
The dye spread in a circular form, so that;
area = 

r =
=
= 7.5 mm = 0.75 cm
area =
×
= 1.7679 
time = 15 minutes = 15 × 60 = 900 seconds
So that;
diffusion rate = 
= 0.0019643
/s
Diffusion rate is 1.96 ×
/s
