How does a nerve signal travel?
Molecules signaling through plasmodesmata.
An electrical signal traveling as a wave.
Molecules signaling through gap junctions.
Pheromone signal traveling between organisms.
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

Each species produces more offspring than will survive to reproduce.
Individuals within a population have slightly different traits.
Individuals within a population compete with each other for limited resources.
Individuals that are better equipped to live in an environment are more likely to survive and reproduce.
ALL of the above are part of Darwin’s theory of natural selection.

I’m confused with this question
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.

Answer these three questions to summarize what you have done in this project.
1. How did you model mutations in this project?
2. How are the three mutated strands similar to each other? (Hint: Think about the type of mutations modeled.)
3. How are the three mutated strands different from each other?
A mutation means an alteration in the nucleotide sequence of the genome of an organism.
What is mutation?Your information is incomplete. Therefore, an overview will be given. A mutation is a change in a DNA sequence.
Mutations can be from DNA copying mistakes that are made during cell division, the exposure to ionizing radiation, and exposure to chemicals called mutagens.
There are three types of DNA mutations which are base substitutions, deletions, and insertions.

Classify each action as a cause or an effect of climate change.
Answer:
Hope the below helps!
Explanation:
Cause:
Fossil fuels burn
Cities become more industrialised
Human population grows worldwide
Effect:
Glaciers melt
Climate changes
Rain falls in unusual amounts
To know the difference, you have to think about what might create changes. E.g. Human population grows worldwide, so each person has a carbon footprint, releasing more carbon emissions into the atmosphere. This means that the climate changes!

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.

Female sea turtles prefer to lay their eggs on dark, sandy beaches. Once the eggs hatch, the turtle young use the light of the moon to guide them to the ocean. They must enter the ocean quickly in order to find food and avoid the many predators that can locate them on the beach.
As more homes and businesses are built along the coastline, the sea turtles become more threatened. Which of the following types of pollutions from homes and businesses would have the greatest impact on sea turtles finding their way to the ocean?
A.
noise
B.
light
C.
air
D.
water
answer
B.
light
Answer: Yes, the correct answer is B: Light.
Explanation: When baby turtles hatch from their eggs on the sand at night, they rely on the moonlight and its reflection on the water to guide them towards the water. With houses and new buildings being built along the shoreline, the new hatchlings get confused and can tend to follow the bright lights of the houses and buildings instead of the moonlight, putting them in danger of many different harmful things.
