The diagram below shows a hand warmer. It uses a controlled burn of a type of lighter fluid called naphtha.



The device has a refillable reservoir that holds the naphtha liquid. The fuel moves into a glass fiber burner, which absorbs the fuel and allows it to burn slowly without producing a flame. Oxygen reaches the burner through the holes on the cap at the top of the device. As the fuel is burned, heat is conducted to the metal casing of the device.

When the hand warmer is tested, it becomes too hot and uncomfortable to hold. How could the device be modified to solve this problem?
A.
by increasing the size of the fuel reservoir so that it can store more liquid fuel
B.
by replacing the glass fiber burner with a material that does not soak up liquid fuel
C.
by attaching a covering to reduce the amount of oxygen entering the device

What leads to the likelihood that that there are successful traits in an ecosystem that will allow organisms to survive and reproduce in changing conditions?
A. less biodiversity
B.smaller food webs
C.greater biodiversity
D.specialist consumers

Answers

Answer:

C. greater biodiversity

Explanation:

Biodiversity refers to the variation in the kind of species in an area/ecosystem. In other words, biodiversity or biological diversity is how life differs from one another. An increase in biodiversity is of great ecological importance.

One of this importance is that; it leads to the likelihood that that there are successful traits in an ecosystem that will allow organisms to survive and reproduce in changing conditions. This means, in a nutshell, that it increases the survival chance of species in adverse conditions via the possession of variant traits or characteristics.

Read the following summary, which describes blood flow and heart output in space. Then, answer the question.

The heart doesn't have to do as much work to pump blood when in orbit. After only one day beyond Earth's gravity, astronauts have a lower blood volume. They can lose as much as 20 percent of their blood volume while on a space mission. Since the body has less blood to push around and the heart is pushing more blood with each beat, an astronaut's heart rate also slows down to compensate.

most likely occur?
Energy from the sun would not be absorbed by plants
Carnivores would have no source of energy
Essential elements would not be available to plants
Herbivores would lose their source of energy and nutrients

Answers

Answer:

If decomposers are removed from ecosystem,there would be no organic nutrients and all the dead plants would destroy the animals habitat. The ecosystem will be fill by plants and animal wastes as there will be no decomposition of waste material.

If the decomposers were removed from an ecosystem then essential elements would not be available to plants. The correct option is C.

What are decomposers?

Decomposers eat dead things like leaf litter and wood, as well as animal carcasses and feces.

As Earth's cleanup crew, they provide a valuable service. Dead leaves, insects, and animals would pile up everywhere if decomposers did not exist.

They play a critical role in decomposing complex compounds (dead organisms) into simple components.

Scavengers and decomposers break down dead plants and animals. They also decompose other waste of organism.

Decomposers are critical components of any ecosystem. Plants would not receive essential nutrients if they were not present in the ecosystem, and dead matter and waste would accumulate.

Thus, the correct option is C.

Puzzle 8

Answers

Answer:

The first answer  is 1

The second answer is

Explanation:

From the attached image, we are giving a clue that there are 5 Hibiscus flowers.

So, each symbol of the Hibiscus flower is 5.

1st row: Hibiscus + Tree = 14

⇒ 5 + Tree = 14

∴ Tree = 14 - 5 = 9

This means that the tree represents 9

2nd row: Sunflower + Hibiscus = 13

⇒ Sunflower + 5 = 13

∴ Sunflower = 13- 5 = 8. This means that the sunflower represents 8.

3rd row: Tree - sunflower = 9-8 = 1

4th row: Sunflower + tree = 9+8 = 13

Last row: Hibiscus(5) × Sunflower(8) ≠ Tree (9)

Why are food webs more realistic than food chains?
There are more animals
Most organisms eat more than one thing
Most organisms eat each other
Most organisms live on their own

Answers

Answer:

The correct answer is -most organisms eat more than one thing.

Explanation:

Food chains are the linear representation of easier visualization of trophic levels or movement of energy through the ecosystem. However, in reality, consumers can depend on more than one producer or other consumers for their food, and energy and interaction among these organisms are not that simple as it shows in the food chain. This makes the food webs to be more realistic than simple food chains.

The food web gives a better idea of the complexity of the various components and movement of energy in an ecosystem because the food webs is are the representation of interaction and interrelation of many different consumers and producers in an ecosystem.

The crustal feature is most likely found between the South American and African plates is folded mountain. The correct option is A.

What is folded mountain?

When two or more of the tectonic plates of Earth are forced together, fold mountains are formed.

Rocks and debris are bent and folded into rocky outcrops, hills, mountains, and entire mountain ranges at these interacting, compressing limits. Orogeny, a process, is what produces fold mountains.

While having a narrower width than their length, fold mountains are very long.

Concave and convex slopes are typically present on opposite sides of fold mountains. Most fold mountains are located on the edges of continents that face the ocean.

A student created a chart to categorize plates according to the different boundary types. The folded mountain is most likely the crustal feature that lies between the South American and African plates.

Thus, the correct option is A.

The main difference between Mysteceti and odonticeti whales is the presence of feeding behaviour. Mysteceti whales also known as baleen whales which have baleen plates that capture prey from sea water while on the other hand, odonticeti whales have teeth which helps these whales to hunt aquatic animals. Baleen whales have baleen plates, or sheets, which sieve prey or food from seawater whereas toothed whales have teeth which helps them to actively hunt fish, squid and other sea creatures. The number of blowholes also different in both whales, Odontoceti whale has only 1 blowhole, but the Mysticeti has two blowholes in its body.
