Which term best describes the community shown in the photograph?

Final answer:

The incident in Donora, Pennsylvania led to the enacting of air pollution laws, including the passage of the Clean Air Act in 1954. This event significantly influenced environmental regulations, setting emission limits and advancing command-and-control policies to reduce industrial pollution.

Explanation:

The incident in Donora, Pennsylvania had a profound impact on environmental regulation in the United States. In 1948, Donora was the site of one of the worst air pollution disasters in the nation's history, when a combination of a temperature inversion, local industrial pollution, and the burning of soft coal resulted in a thick smog that persisted for five days. As a result of the Donora Smog, which caused severe health issues and deaths among the local population, enacting air pollution laws became a priority.

A significant outcome of this event was the passage of the first Clean Air Act in 1954, a key piece of legislation that was further strengthened in subsequent years. This act led to regulations that directed industries to reduce emissions, and it pioneered the approach of setting limits on pollutants, leading to the improvement of air quality and the reduction of negative health effects.

These air pollution laws are a form of 'command-and-control regulation', wherein governments specify allowable limits of emissions and require the installation of pollution-control technologies in factories, power plants, and on vehicle tailpipes. By enforcing these regulations, firms have to account for the social costs of pollution, representing a move towards the internalization of environmental externalities into the production process.

Answer: Camouflage or deterring predators

Explanation: Mimicry can help an organism blend into its surroundings if they are resembling something in the environment.

It can also help deter predators if they are resembling a poisonous or venomous organism; an example of this is the non-venomous king snake, which mimics the venomous coral snake to deter predators from eating it.

Answer:

1). Its advantages is defense adaption.

2). It makes them look like an uninteresting object.

3). It becomes a specie that potential predators normally avoid because it posses an unpleasant or harmful feature like a foul smell or taste, or a poisonous sting.

Note: Several insects look like dead leaves and bird droppings and so, although noticed, are ignored by their potential predators. Example is in Mullerian mimics, unrelated animals like the striped polecat and the striped weasel of the savanna have similar broad white stripes on a black body. Their enemies associate the conspicuous appearance with the foul smelling liquid they squirt, and so avoid them.

Answer:

Explanation:

Answer:

Red flowers (dominant) crossed with white flowers (recessive) can yield pink flowers. Pink is the heterozygous condition in a trait that shows incomplete dominance. If pink flowers are crossed with white flowers, assuming random chromosome segregation, what percentage is expected to be red flowers?

RR x rr= Rr, Rr, Rr, and Rr

Red x White= Pink heterozygous

Rr x rr= Rr, Rr, rr, and rr

Pink x White= 0% as both Pink and white shares it with 2:2 or 50:50%

Explanation:

Final answer:

When pink flowers (incomplete dominance, CRCW) are crossed with white flowers (CWCW), the resulting phenotypic ratio is 1 pink (CRCW) to 1 white (CWCW). No red flowers (CRCR) will be produced, so the expected percentage of red flowers is 1) 0%.

Explanation:

The question is asking about the expected phenotypic outcome when you cross pink flowers with white flowers in a case of incomplete dominance. In incomplete dominance, a heterozygous organism (with one dominant and one recessive allele) shows a phenotype that is intermediate between the homozygous dominant and homozygous recessive phenotypes.

For example, in snapdragons, red flowers (CRCR) crossed with white flowers (CWCW) yield pink flowers (CRCW), where pink is the heterozygous condition. If pink flowers (CRCW) are crossed with white flowers (CWCW), the Punnett square combination will give us CRCW (pink) and CWCW (white) offspring. No CRCR (red) offspring will be produced because the white parent can only pass on the CW allele. So, the correct answer for the expected percentage of red flowers is 0%.

The genotypic ratio from this cross is 1 CRCW:1 CWCW, leading to a phenotypic ratio of 1 pink:1 white. No red flowers would be produced in this cross.

Answer:

A diatom is a(n) autotrophic algae because it has chlorophyll.

Explanation:

Diatom is a type of unicellular and eukaryotic algae which has the ability to make their own food like plants from sunlight due to the presence of chlorophyll pigment. Diatom helps in fixation of carbon in the process of photosynthesis. About 20 percent of carbon fixes by diatom and plays an important role in climate change. It lives in water and provides food for many herbivores.

Answer:

D. Human activity is the main influence on recent climate change,

Explanation:

Climate change occurs due to human activities which releases harmful gases that pollute our environment. For example, carbondioxide is a greenhouse gas which is released in the atmosphere through vehicles and industries. This carbondioxide absorb heat from the reflected solar radiation which increases temperature of the environment and causes global warming.

Answer:

Human activity is the main influence on recent climate change.

Explanation:

Darwin's theory of evolution is most often associated with his study of finches.

He noticed that finches present on different islands had different types of beak suited to that particular environment. On one island, the beaks were better suited for cracking nuts. On another, they were long and thin for searching for bugs.

These finches came from a common ancestor, and migrated to different islands. Due to natural selection and lack of intermixing between the islands, the finches developed different traits over time.

He did this work with other species as well, noting that different species had developed distinct features that suited them to their environment.

Darwin also studied fossils, which provided evidence that animal form (anf function) changed over the course of thousands of years. This supported his idea of evolution that resulted from natural selection.

Blood is needed to keep us alive. It brings oxygen and nutrients to all the parts of the body so they can keep working. Blood carries carbon dioxide and other waste materials to the lungs, kidneys, and digestive system to be removed from the body. Blood also fights infections, and carries hormones around the body.

Answer:

C

Explanation:

usually it is carrying the oxygen to to other parts of the body hence why the blood is red, our blood is blue till it meets oxygen, and occasionally it is carrying the bad waste in the body to get out so i believe that it is C

Phosphorus is a significant components in the makeup of lipid bilayer.

Phosphorus is a component of

bones.

Phosphorus is a key nutrient to increase crop yield.

Explanation:

Phosphorus is an element that exist in two forms as either red phosphorus or white phosphorus. It is not found on Earth because it is very reactive. Phosphorus. It is the second most plentiful mineral in the body and it makes up to 1% weight of the food. It is found in food such as meat. It is a major component of lipid bilayer. It is a component of bones and teeth. It play important roles in photosynthesis by capturing and converting sun light energy into useful compounds. It is important to increase plants yield.

Phosphorus cycle is the movement of phosphorus from the atmosphere to the Earth and back to the atmosphere.

At a plate boundary where two thick plate edges of continental crust are coming together, subduction occurs on Earth’s surface.

Subduction zones are tectonic boundaries plates where two plates connect and one plate push under the other.

This process results in earthquakes and volcanoes.

The oceanic crust sinks into the mantle.

Subduction zones are found in the "the ring of fire", where most of the volcano and earthquake happens.

Influence of plant under gravity or light is described below.

Explanation:

Final answer:

An experiment to discern whether gravity or light has a stronger influence on plants could involve observing plant growth under varying conditions of light and simulated gravity, employing methods such as clinostats for gravity and directional light sources.

Explanation:

The question about whether gravity or light has a stronger influence on a plant is rooted in the field of Biology. The phenomena of gravitropism and the effects of red and blue light on plant growth and metabolic activities are pivotal to understanding these influences. Gravitropism is the growth response of a plant in relation to the force of gravity, with roots showing positive gravitropism by growing downwards and shoots showing negative gravitropism by growing upwards.

Designing an Experiment:

To test the stronger influence between gravity and light on a plant, you could design an experiment where plants are grown in two sets of conditions - one where light direction varies and gravity is constant, and another where gravity varies and light direction is constant. This could involve using a controlled environment with artificial light and a rotating space to simulate changes in gravity. Observing growth patterns, direction, and general health of the plants in these varied conditions would offer insights into which factor has a stronger influence.

For instance, by rotating plants on a clinostat to simulate microgravity and using directional light sources, we can observe differences in growth direction and vigor as each variable changes. This comparative study would contribute valuable insights into plant responses.

Four conditions for fossilization:

Only dead organism or plant

The dead to be buried quickly

Prevention of decaying and decomposition of the dead

Dead to be buried in environment where carbonates precipitate at large

Explanation:

The plants or animals preserved in sedimentation rock are said to fossilized and the process is called fossilization.

Conditions for fossilization are:

1) Only dead organism or plant: Only dead animal or organism are considered for fossilization.

2) The dead to be buried quickly: To preserve the organism a death by natural calamity is best.

3) Prevention of decaying and decomposition of the dead: The animal needs to be kept in anaerobic conditions and ensured that bacteria do not throng and start the decaying process.

4) Dead to be buried in environment where carbonates precipitate at large:

The soil should be rich in mineral rich water in which carbonates are in excess. The carbonates will get deposited on the degrading tissues and the tissue attain the shape of rock formed by carbonates.
