What do all of these samples have in common?

Answer:

factors. Some—such as competition, predation, parasitism, and disease—depend on population density. Others—including natural disasters and unusual weather—do not depend on population density.

.

When unnatural pollutants are exposed to sunlight and heated up, they create ozone. The correct option is a.

It is the resulting pollution from human activity. It covers the use of fossil fuels in manufacturing, transportation, and thermoelectric power plants, as well as industrial gas emissions, mining, processing, and stone crushing.

The physical degradation or contamination of the environment caused by the release of hazardous, dangerous, or toxic chemical substances is known as pollution.

Oxides of nitrogen (NOX) and volatile organic compounds (VOC), commonly referred to as hydrocarbons, undergo chemical interactions that result in ozone. Both close to the earth and high in the atmosphere, this reaction is possible.

Therefore, the correct option is a. ozone.

Explanation:

Kinetic energy is possesed by a body by virtue of its motion. The ratio of the kinetic energy of the car to the boat is 4:1.

The term kinetic energy refers to the energy that is possesed by a body by virtue of its motion.

Now;

Kinetic energy of the car = 0.5 * 2000 * v^2

Kinetic energy of the boat = 0.5 * 500 * v^2

The ratio of the kinetic energy of the car to that of te boat is; 0.5 * 2000 * v^2/0.5 * 500 * v^2 = 4:1

Answer:

D. Capillary action

Explanation:

Capillary action is defined as "the movement of water within the spaces of a porous material due to the forces of adhesion, cohesion, and surface tension." All of the other answers are technically right because they are all present when the water is traveling upward, but Capillary Action is the most correct answer provided because it is the description of what is hapeneing as a whole.

Plants acquire energy through a method known as photosynthesis which is different from animals. Plants make their food from the process called photosynthesis as they are autotrophs while animals depend on their food on plants and they are called herbivores.

Autotrophs are the organism that can produce its own food using light, water and carbon dioxide or some other chemicals. They are also known as primary producers.

The most familiar type of autotrophs are plant but apart from plants many different types of autotrophic organisms are there. For example, algae which live in water, phytoplankton which live in ocean and some type of bacteria.

Mostly autotrophs used the process called photosynthesis to make their own food. In this process, Autotrophs used energy from the Sun to convert water obtained from the soil and carbon dioxide obtained from the air to produce a carbohydrate called Glucose . It give energy to the plant.

Some rare autotrophs produces food through a process called Chemosynthesis . In this process, they make their own food using energy from chemical reaction combining Hydrogen Sulphide or Methane with oxygen . Organism that uses Chemosynthesis for making their food lives in extreme environment . For example, Bacteria live in active volcanoes oxidize sulphur to produce their own food.

Thus, plants acquire energy through a method known as photosynthesis which is different from animals. Plants make their food from the process called photosynthesis as they are autotrophs while animals depend on their food on plants and they are called herbivores.

Explanation:

Frog undergoes a complete metamorphosis. It includes the egg, tadpole, froglet and then adult frog stages. In complete metamorphosis the hatchling does not resemble the parent and changes as it grows to be an adult.

During metamorphosis the tadpole will develop back legs first, then front legs.  Around 6 weeks of life the mouth starts to widen.  Sometime around 10 weeks the froglet’s, as it is now called, eyes start to bulge out and the tail begins to shrink and eventually disappear.  When the lungs finish developing the froglet makes it’s way onto the land and, Ta-da! It’s a frog!

Answer:

is created from careful research and logical reasoning

is able to be tested using validated techniques

Explanation:

A hypothesis can be defined as a prediction/expectation that is made in order to understand a phenomenon from the real world. This prediction must be testable and measurable by using the scientific method. In science, a good hypothesis clearly defines the relationships between two or more variables (independent variables and dependent variables). Moreover, a good hypothesis must also be written in simple and precise language, which means that its statements must be understandable (and verifiable) for any person and/or researcher working in the field.

Clear-cutting the rainforest

Explanation:

Density-independent factors of a population are factors that limit the size of a population irrespective of the density of the population.

A limited food source can only be defined by the size of a population, diseases will spread faster in high-density populations, and an increase in the population of a predator will cause a decrease in the population size of the predator's prey.

Clear-cutting of the rainforest means automatic destruction of the habitat of the poison dart frog's population, no matter the population size. Hence, clear-cutting of the rainforest is considered as the density-independent factor in this case.
