In a balanced ecosystem with predators and prey, if the prey population decreases then....?

Answers

The predator population will decrease as well

Answer:

Predator population will also decrease

Explanation:

This is because the predators are dependent on their prey without the prey they would starve and die out so with less possible food the less of a population for what ever eats that prey which can lead to a chain reaction throughout the ecosystem however it is also the other way around too the more possible food the more chance for babies to be born and not starve to death.

How can temperature and pH affect enzymes?

Answers

Answer:

raising temperature generally speeds up a reaction, and lowering temperature slows down a reaction. extreme pH values can cause enzymes to denature.

enzymes work best within specific temperature and pH ranges, and sub-optimal conditions can cause an enzyme to lose its ability to bind to a substrate.

Which correctly lists three forms of frozen water?

O dew, frost, rain

O frost, hail, sleet

O hail, rain, sleet

Orain, dew, frost

Answers

Answer:

b

Explanation:

The option that correctly lists three forms of frozen water is "frost, hail, sleet". Therefore, option (B) is correct.

What is frozen water?

Frost is created when water vapor condenses and freezes onto a surface, like the ground or a window.

Hail is produced when powerful updrafts in thunderstorms carry raindrops high enough that they freeze into ice, forming large balls of ice that fall to the ground. This process results in the formation of hail.

Sleet is created when raindrops pass through a layer of cold air close to the ground. This causes the raindrops to freeze into small ice pellets before they reach the ground's surface.

The siboglinid tube worm, found at deep-sea hydrothermal vents and cold seeps, has no digestive tract. It relies on symbiotic bacteria that live in the tube worm’s tissues. The bacteria oxidize hydrogen sulfide or methane for the worm.

What type of relationship is this?

Answers

Answer:

mutualism

Explanation:

There is a mutual benefit in both parties.

The relationship between the siboglinid tube worm and the symbiotic bacteria that live in its tissues is an example of mutualism, a type of symbiotic relationship in which both organisms benefit from the interaction.

What is a mutualistic relationship?

In a mutualistic relationship, both organisms benefit from their interaction with each other. This is different from parasitic or commensal relationships, where one organism benefits at the expense of the other, or where one organism benefits while the other is neither helped nor harmed. In the case of the siboglinid tube worm and the symbiotic bacteria that live in its tissues, the tube worm benefits from the bacteria's ability to oxidize hydrogen sulfide or methane, which provides the worm with a source of energy and nutrients. This is important because the tube worm has no digestive tract of its own and cannot obtain food directly from the environment.

Hence, the relationship between the siboglinid tube worm and the symbiotic bacteria that live in its tissues is an example of mutualism.

How do i know if its entering or leaving or neither just by the precentage?

Answers

Answer:

1. Shrink

2. Swell

3. Neither

Explanation:

The percentage of water indicates how pure the water is, i.e. how concentrated the molecules of water are.

The higher the percentage of water, the more water molecules there are in the space.

Water molecules move from a high concentration to a low concentration across a semi permeable membrane, by the process of osmosis.

In beaker 1, the water outside is 89%, and inside the bag is 92%. That means the water inside the bag is at a higher concentration than outside. That means water will leave the bag, moving from a high concentration to a lower concentration outside. The bag will shrink.

In beaker 2, the water outside is 97%, and inside is 92£%. That means the water inside the bag is a lower concentration than outside. That means water will enter the bag, moving from a higher concentration outside to a lower concentration outside. The bag will swell.

In beaker 3, the concentration of water inside and outside is the same. That means they are in an equilibrium (the movement is balanced) so neither will occur
