Explain what caused the existence of the dark-colored peppered MOTHS:)
Answer:
The moths adapted to the environment they were in which was heavily polluted and the spots helped it blend into the environment. It was in the UK somewhere I don't remember where though.
Explanation:
The peppered moth's evolution is an example of how air pollution during the Industrial Revolution caused directional color changes in the moth population.
What are the adaptation of dark-colored peppered moths?The genetic basis for color was eventually discovered. Moths inherited their color from their ancestors. Eggs from light moths became light moths, whereas eggs from dark moths became dark adults.
At that time, a manifestation of industrial melanism was the rise in the number of dark-colored moths.
The moths blended in with the severely contaminated environment they were in thanks to their markings, which helped them adapt to it. Although I can't recall where, it was in the UK.
Therefore, A mutation in one moth's DNA resulted in the dark color, and the mutant gene was passed on to all the moth's progeny.

The source of a sound moves away from the listener. Listener has the impression that the source is ________ in pitch and the frequency has_______.
A.) lower. Increased
B.) lower, decreased
C.) higher, decreased
D.) higher, increased
Doppler Effect is defined as the change of frequency of a sound or light wave produced by a moving source and a stationary observer. The waves when they move towards the object compresses.
The correct answer is:
Option B. lower, decreased
The Doppler effect can be explained as:
1. The listener will have the impression that the moving source is higher in the pitch as it moves away from the listener.
2. The frequency of the waves will be decreased because the time between the successive sound waves is lengthened or increased.
Therefore, the pitch will be lowered and the frequency will be decreased.

What is her independent variable?
What is a hypothesis she might write for her experiment?
Thank you
Answer:
Independent variable: Angle or direction of light
Hypothesis: IF the light is placed on the plant at a particular angle, THEN the plants will grow in that direction
Explanation:
In an experiment, the HYPOTHESIS is a testable explanation given to explain an observed problem or to answer a question. According to this experiment,
a student wants to investigate the effects of phototropism in bean plants i.e. how light affects the direction of plant growth. The scientific question is "How does light affect the direction which plant grows?". Therefore, a possible hypothesis will be:
IF the light is placed at a particular angle or direction, THEN the plants will grow in the direction of that light source.
- The independent variable is the variable that the experimenter changes or manipulates in order to effect a measurable response (direction of growth). In this experiment, the DIRECTION OR ANGLE OF THE LIGHT SOURCE IS THE INDEPENDENT VARIABLE.

what does photosynthesis form in a leaf first
Explanation:
The first stage of photosynthesis is the light dependent reactions. These reactions take place on the thylakoid membrane inside the chloroplast. During this stage light energy is converted to ATP (chemical energy) and NADPH (reducing power).
The light-dependent processes make up the initial phase of photosynthesis. On the thylakoid membrane inside the chloroplast, several processes take occur. In this phase, light energy is transformed to ATP and NADPH, two chemical energies (reducing power).
What is thylakoid membrane inside the chloroplast?The light processes of photosynthesis are carried out by a system of connected internal membranes called thylakoid membranes in a chloroplast.
Numerous proteins and chlorophyll molecules can be found in each thylakoid membrane. Clusters of chlorophyll molecules are called photosystem.
Plants use chlorophyll pigments to absorb light energy and convert it to electrons, which are subsequently transmitted down a protein chain in the thylakoid membrane.
Therefore, thylakoid membrane inside the chloroplast in which photosynthesis form in a leaf first.

Explain the difference between food-chain and ecosystem.Explain the difference between food-chain and ecosystem.
Answer:
A food chain shows the transfer of energy through a single chain of animals. For example, energy comes from the sun, a producer uses energy from the sun as food, a secondary consumer eats the primary consumer, a tertiary consumer eats the secondary consumer, and so on. An ecosystem contains many intertwining and interlocking food chains. Ecosystems contain both abiotic and biotic factors.
• Food chain is a chain of species and organisms where energy transferred from one trophic level to another.
• Level of energy transferred decreases as one move from one level to another.
• It is single directional transfer or flow of energy.
• All living species need energy for growth and survival
• Plants are consider producer since they make their food using sunlight, soil and other elements.
• Animals are consider consumers since they gain energy from eating other plants and animals.
Generally we have four Trophic level:
• Producers
• Primary consumers
• Secondary consumers
• Top consumers
Example:
• Vegetation→ Grasshoppers → Frog→ Snake → Eagle
• Plant → Frog → Snake → Peacock
• Interaction between living and non living component i.e. biotic and abiotic factor makes up an ecosystem.
• Biotic factor consists of plants, animals and decomposer.
• Abiotic factor consists of mountains, light, soil, air and water.
• Example: Forest is an terrestrial ecosystem it consist of plants and animal. A lake is an example of aquatic ecosystem aquatic plants and animals.
