Define surface tension??​

Surface tension could be defined as the property of the surface of a liquid that allows it to resist an external force, due to the cohesive nature of the water molecules.

What's surface tension?

[tex] \large \boxed{\mathfrak{Answer \: with \: Explanation} \downarrow}[/tex]

Okay, so surface tension is the energy which is required to increase the surface area of a liquid due to intermolecular forces. The formula for surface tension is :-

How would adding finer particles to the sand affect porosity?

Answers

Explanation:

Porosity depends on the size, shape, and mixture of grains and particles that compose soil and rock. For instance, small particles such as clays can compact more closely together, reducing the amount of porosity. However, larger particles such as sand and gravel will have more spaces available between them.

The extensive size of the fires that burned Yellowstone National Park in 1988 caught both land managers and ecologists by surprise. Many forests suffered intense infernos that removed virtually all vegetation. Some speculated that the park would never recover. Based on what you learned and disturbance and succession, is it likely that the park was irrevocably altered

Answers

Answer:

It is not possible that the park has been irrevocably altered.

Explanation:

The fires are part of the ecology of Yellowstone National Park, and there is a very low risk that this park will be irreversibly modified after a fire. It is scientifically proven that Yellowstone has recovered from fires in a period of thirty years and that the risk of this recovery not happening is very low. In addition, the natural fires that occur in Yellowstone are, in a way, important for the maintenance of the park's ecosystem, since they are able to break the seed dormancy  that are in the soil, in addition to promoting the opening of the serine pine cones.

Seed dormancy is the difficulty of germinating that some seeds present, even in an environment with favorable conditions for germination.

Why the Carbon must be cycled through the carbon cycle?

Michael discovers that a fish breathes less often in cool water. He correctly hypothesizes that A. the fish slows down in cool water, and does not need as much oxygen. B. the fish is eating, and does not have time to breathe as much. C. the fish is sleeping, and does not need as much oxygen. D. there is less oxygen in cool water, so the fish breathes slowly.

Answers

Answer: then it’s d there is less oxygen in cool water

Explanation:

There are many explanations for Michael's observation that fish breathe less frequently in cold water. However, his hypothesis that the fish returns to the cold water and requires less oxygen seems possible.

What type of animals fish are?

Fish are cold-blooded animals, which means their environment controls their body temperature. Their metabolic rate, activity level, and oxygen requirements decrease as water temperatures drop.

As a result, fish can slow down in cold water, reducing their oxygen demand and reducing their breathing rate.  Oxygen solubility may also play a role in whether fish breathe less in cold water. As the water temperature decreases, the ability of oxygen to dissolve in the water also decreases. Because of this, cold water can have less oxygen available, which can cause fish to breathe more slowly to compensate for the lack of oxygen.

Because fish need oxygen to digest food, they are likely to eat and breathe less. It's basically a joke that the fish are resting because fish don't have an obvious resting cycle and will move and swim when they are resting.

Finally, Michael's hypothesis that fish breathe less in cold water is plausible as it suggests that fish slow down and don't need as much oxygen.

can someone please answer this question?

Answer:

C

Explanation:

Scientists analyzed data collected over a period of years in a game reserve in South Africa to test the hypothesis that competition with lions limits the abundance of leopards in the same community. The game reserve encompasses a variety of habitats, from open grassland to wooded areas around rivers and streams. It contains most of the indigenous mammal species and an adequate availability of their prey. For the most part, the leopards and lions show similar habitat preferences in the reserve.

The mass of the average lion is about three times that of the average leopard. The scientists analyzed several factors that might influence the abundance of each population, including the sizes of the animals preyed on by each species

Size of Prey Animal Percent of Leopards’ Prey (±2SEx¯) Percent of Lions’ Prey (±2SEx¯)
Small 34 ± 2 3 ± 1
Medium 63 ± 3 23 ± 2
Large 3 ± 1 36 ± 4
Very large 0 38 ± 3

Because competition with lions might affect the population size of the leopards, the scientists also analyzed data on the lion and leopard population sizes in the game reserve (Figure 1).

Required:
Describe what scientists mean when they refer to an ecological community such as that shared by the leopards and lions.

Answers

Answer:

The correct answer would be - these are the ecological community that shows the interspecific competition.

Explanation:

In this ecological community, both predators lion and leopards are living together and by the given data and information it is evident that they both share the same habitat and they both depend on the same prey for their food.

This cause competition between both lion and leopard for food and habitat. Such competition or interaction is referred to as the interspecific competitions negatively impacted by the presence of the other because they will have less food.

Answer

An ecological community refers to all of the interacting populations in a defined habitat.
