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.

How do changes in environmental factors affect the predation habits of the blue heron?
Explanation:
blue heron feed on eggs, provided by Eagles. however, eagles feed on adult blue herons, their eggs, environmental factors are; changes in weather, they feed on tadpoles and frogs during a wet spring/summer..dry conditions create, more lizards, snakes,etc., which they also feed on for survival.. adaptation 2 conditions create opportunities for predators and prey...
During spring/wet summer Blue herons feed on Frogs and Tadpoles while they predate/feed on lizards and snakes when the season becomes drier.
The predation habits of the Blue heron is affected by the changes in weather conditions year round, Blue herons can predate/feed on different preys such as ; eagle eggs, lizards, snakes and tadpoles.
The type of prey the Blue heron feeds on is solely dependent on environmental factors at each time of the year. Blue herons are found mainly on the shores of water bodies.
Hence the changes in environmental factors makes the Blue heron to feed on frogs during spring/ wet summer and to feed on lizards when the season becomes drier.

darwin's experiments are just one way to study phototropism. a student wants to investigate the effects of phototropism in bean plants. she places a light source above one plant, at a forty-five degree angle to another, and at a ninety-degree angle from the third.
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.

Which of the following is possible when a populations carrying capacity is reached or exceeded?
population growth will slowly level off
Population continues to grow exponentially past the carrying capacity
population growth will crash
Carrying capacity of the ecosystem is reduced
Answer: population growth will crash
Explanation: Every organism follows a growth curve to complete its life cycle. When the organism exceeds its carrying capacity in the environment, then the population crashes.
There are mechanism present in the environment to prevent growth after a certain extent of time. Example: Plants only have the ability to regenerate after being crashed but other organism lack this property.
After a certain extent, population crashes along with its environment.

Answer:
Epiphyte
Explanation:
The correct answer would be an epiphyte.
An epiphyte is a plant that grows on another plant for support only. Epiphytic plants are capable of manufacturing its own food using photosynthesis and perform every other life processes independently but only depend on another plant for anchorage. All their material requirements such as water and minerals are derived from the air surrounding them.
What is the name of the site on a chloroplast where half of the reactions in
photosynthesis occur?
Answer:
thylakoid
Explanation:
The light reactions take place in the thylakoid. There, water (H2O) is oxidized, and oxygen (O2) is released. The electrons that freed from the water are transferred to ATP and NADPH.
environmental scientists collect air samples so they can test the quality of the air, they start with rigid metal containers that are completely empty the air has been pumped out of them what happens to the pressure inside the container and the volume of the container as air enters it?
Answer:
Here's this. Let me know if that helps :)
Explanation:
The sampling procedures must be designed so that samples of the actual dust concentrations are collected accurately and consistently and reflect the concentrations of dust at the place and time of sampling. Sufficient number of 6-hour area samples in each distinct work area of the plant should be collected at locations which provide representative samples of air to which the worker is exposed. In order to avoid filter overloading, sampling time may be shortened when sampling in dusty areas. Samples in each work area should be gathered simultaneously or sequentially during a normal operating period. The daily time-weighted average (TWA) exposure of each worker can then be determined by using the following formula:
As the air which is pumped out of the empty rigid metal containers the pressure inside the container increases as well as the volume of empty container increases to occupy the space.
What are pressure and volume changes?The container experiences changes in the amount of pressure and volume, when the matter is added or removed from a container. An increase is experienced when something is added to the container.
The increase in volume and pressure are observed because as the air is pumped out of the container it tries to spread out and volume increases as the particles starts to occupy the empty space present in the container. With the particles occupying volume of container, the air particles try to move faster and as a result hits the container harder which lead to increase in the pressure inside the container, and the volume of air pumped out of the container.

A) Outline the three stages of cell signaling.
B) The aldosterone hormone is released by the adrenal gland. Explain the target cells signal transduction pathway response to aldosterone.
Note: Please help Im on a time crunch!! <3
Answer:
A. The process of cell signaling includes three stages: reception, transduction, and response. in reception, a chemical signal binds to a cellular protein, typically at the cell's surface. In transduction, binding leads to a change in the receptor that triggers a series of changes along a signal - transduction pathway. In response, the transduced signal triggers a specific cellular activity.
B. When aldosterone hormone is released by the adrenal gland: first, the Endocrine System secretes hormones into the blood and hormones are transported within the blood and are distributed to target cells throughout the body, then any cell in the body with a receptor for the hormone is targeted, there is a relatively slo reaction time which could range from seconds to minutes to hours, the effect of the hormone released is usually felt throughout the body but the response is long - lasting from minutes to days to weeks and my continue after the stimulus is removed.
