Nerve signal travel by molecules signaling through gap junctions
A nerve impulse begins when a neuron receives a chemical stimulus. The nerve impulse then travels down the axon membrane as an electrical action potential to the axon terminal. The axon terminal releases neurotransmitters that carry the nerve impulse to the next
Answer molecules signaling through gap junctions

Which organ of the body is responsible for water absorption *
Liver
Heart
Kidneys
Gonads
Answer:
Technically, it's the kidneys, but if it's also with the digestive system, it would be the large intestine. However, this is not that type of question, so it would be the kidneys.
Explanation:
A survey was conducted to estimate the population of barnacles (figure 1) in two coastal areas (i.e. A and B). The dimension of coastal area ‘A’ is around 20 m and 26 m. The dimension of coastal area ‘B’ is around 14 m and 15 m
Sampling in both areas was conducted using 1 x 1 m quadrat. Six quadrats were sampled randomly in each area. The numbers of barnacles in each quadrat as the following.
Area Q1 Q2 Q3 Q4 Q5 Q6
A 2 1 3 1 4 2
B 12 11 5 3 6 2
1. Calculate the estimated population of barnacles in both areas A and B. Please show the details of calculations. [5]
2. Discuss your findings. [5]
Based on the data provided;
Estimated population of Barnacles in A is 1128 BarnaclesEstimated population of Barnacles in A is 1365 Barnacles the population density of Barnacles in B is greater than that in A.What is a population density?Population density is the number of organisms per unit area of a given geographical area or location.
Population density gives an idea of how densely or sparsely populated a given area is.
Population density = number of organisms/area of land.The area of quadrant = 1 m × 1 m = 1 m^2
Total number of Barnacles in 6 quadrant sample A = 13
Average = 2.17
Population density = 2.17/1m^2 = 2.17 /m^2
Total number of Barnacles in 6 quadrant sample B = 39
Average = 6.5
Population density = 6.5/1m^2 = 6.5 /m^2
Area of A = 20 m × 26 m = 520 m^2
Estimated population of A = 520 m^2 × 2.17 /m^2
Estimated population of Barnacles in A = 1128 Barnacles
Area of B = 14 m × 15 m = 210 m^2
Estimated population of Barnacles in B = 210 m^2 × 6.5 /m^2
Estimated population of Barnacles in B = 1365 Barnacles
From the above results, the population density of Barnacles in B is greater than that in A.

Question 7 options:
Osmosis is the movement of gases, such as oxygen and carbon dioxide. Diffusion is the movement of water.
Diffusion is the movement from areas of high concentration to areas of low concentration. Osmosis is a type of simple diffusion.
Both osmosis and diffusion must occur through a semipermeable membrane.
Diffusion requires the use of energy, but osmosis does not.

Answer:
DNA = Deoxyribo Nucleic Acid .
Answer:
Deoxyribonucleic acidIt is a polymer composed of two polynucleotide chains that coil around each other to form a double helix carrying genetic instructions for the development, functioning, growth and reproduction of all known organisms and many viruses. DNA and ribonucleic acid (RNA) are nucleic acids. Alongside proteins, lipids and complex carbohydrates (polysaccharides), nucleic acids are one of the four major types of macromolecules that are essential for all known forms of life.
