Answers

Answer:

solubility increases witn increase in temperature

Answer:

increases

Explanation:

As temp increases, avg kinetic energy of solvent molecules increases, and move faster randomly in all directions. As a result, the no. of collision between solvent and solid per unit time increases, hence rate of dissolving increases.

Match each species to its story of overexploitation.

a. Dodo
b. Canadian cod
c. Rothschild's orchid
d. Whales
e. Passenger pigeon

1. Multiple species were almost wiped out, but are slowly recovering after a moratorium on hunting them.
2. Once the most populous species of its kind in North America, these were hunted to extinction by 1901.
3. When sailors stocked its island with pigs, the pigs destroyed this species' ability to reproduce.
4. This species was almost wiped out by collectors who prized its rarity.
5. Once a major resource in Canada, the population crashed in the 1990s. Recovery is slow because they cannot reproduce until age 7.

Answers

Answer:

Explanation:

Dodo- When sailors stocked its island with pigs, the pigs destroyed this species' ability to reproduce.

Canadian cod- Once a major resource in Canada, the population crashed in the 1900s. Recovery is slow because they cannot reproduce until age 7.

Rothschild's orchid-This species was almost wiped out by collectors who prized its rarity

Whales- Multiple species were almost wiped out, but are slowly recovering after a moratorium on hunting them.

Passenger pigeon- Once the most populous species of its kind in North America, these were hunted to extinction by 1901.

Overharvesting and using natural reservoirs including plants and animals, when their breeding rate is declining, is called overexploitation.

The correct matches are:

A. Dodo- Option 3. When sailors stocked its island with pigs, the pigs destroyed this species' ability to reproduce.

The influx of new animals in their territory and habitat destruction was the cause of the extirpation of the Dodo bird.

B. Canadian cod- Option 5. Once a major resource in Canada, the population crashed in the 1900s. Recovery is slow because they cannot reproduce until age 7.

They are now threatened species because of overfishing. Their breeding rate is also slow making them endangered species.

C. Rothschild's orchid - Option 4. This species was almost wiped out by collectors who prized its rarity.

The area in which the plant species thrives is now cleared and the plants are wiped out by collectors.

D. Whales- Option 1. Multiple species were almost wiped out, but are slowly recovering after a moratorium on hunting them.

Pollution, contamination and over whaling has led this variety to the verge of endangerment.

E. Passenger pigeon- Option 2. Once the most populous species of its kind in North America, these were hunted to extinction by 1901.

Their habitat loss and overexploitation for their meat are the main causes for which they went obsolete.

Answers

Answer:

Predeators such as us and others that eat these rabbits keep their population in check. Also these rebbots that are being born will die soon also, menaing their popultaion is filling and taking away, then refilling again and again with them dying.

Explanation:

The population of rabbits could have overrun human population ordinarily, but the presence of limiting factors would hinder it.

The limiting factors are biotic and abiotic environmental factors that prevents the population of organisms from getting to their biotic potential. In other words, limiting factors will not let the population of organisms grow perpetually. These factors include:

Competition for limited resourcesDiseasesNatural disastersPredation

In the real sense, the earth has the maximum number of individuals from each species it can support based on the resources it has, otherwise known as carrying capacity. Thus, the population of any species of living organism cannot grow without checks.

what is a dependent variable​

Answers

A dependent variable is exactly what it sounds like it is something that depends on other factors for example a test score could be a dependent variable because it could change depending on several factors such as how much you studied how much sleep you got the night before you took the test or even how hungry you were when you took it. Usually when you are looking for a relationship between two things you are trying to find out what makes the D pendant variable change the way it does.

Many people have trouble Remembering which is the independent variable and which is the dependent variable. An easy way to remember is to insert the names of two variables you are using in the sentence in the way that makes more sense to you. Then you can figure out which is the independent variable and which is a dependent variable.

the Independent variable causes a change in the dependent variable and it isn’t possible that the dependent variable could cause change in the dependent variable

Compare the advantages and disadvantages of demolishing an old building versus renovating it.

Answers

Answer:

Demolishing a building involves pulling down the whole structure and building from the scratch while renovation doesn’t involve pulling down the whole structure. It involves pulling down some parts of the building or simply modifying the building.

An advantage of Demolition is that the individual is able to build from the scratch which permits him/her to have the exact structure wanted.

A disadvantage of this is the high cost incurred on demolition and building from the scratch.

An advantage of Renovation is the less cost involved since it only requires some modifications and not total pulling down of the structure.

A disadvantage of Renovation is the inability to get the exact building taste the individual hoped for.

Explain why scientists the Albert and kaibab squirrels are examples of speciation

Answers

- Kaibab Squirrel gives us one nice example of the evolution that is caused by geographical isolation - about 10,000 years ago when the last Ice Age ended, physical formations in the valley changed in a way that prevented squirrels from reaching the Colorado River. The valley has become a geographical barrier separating forests and squirrels on each edge. One group of squirrels became two separate groups that were no longer able to mate, kaibab squirrels. Abert squirrels are North American species, found across a group of locations. Kaibab squirrels are a subspecies of Abert squirrels, found only in one region in the United States. - Kaibab and Abert squirrel live in ponderosa pine forests, where they build nests of twigs and pine needles. They eat nuts, fruits, and fungi, as well as seeds, bark and twigs from the trees they make at home. The most important source of food in the squirrel Kaibab is the seeds contained in the cones of ponderosa

Answer:

The Abert’s squirrel is found on the south rim of the grand canyon and surrounding states.

The Kaibab squirrel can only be found at the north rim of the canyon.

Scientists believe they were separated by plateau erosion that separated the forests of the Grand Canyon, isolating the Kaibab population of squirrels.

why there are more fungi in a forest than in a field? What role do they play in an ecosystem?

Answers

Answer:

Explanation:

Fungi grows more in damp conditions. There is also more food availibility of food in the forest for fungi. There is more dead matter in forests that fields.

Fungi and other decomposers feasst on dead matter and break them down. This increases soil fertility and allows more plants to grow.

Answer:

The role fungi plays is a decomposer.

Explanation:

Decomposers are plants that don't make their own food. They get their food from breaking down dead plants and animals. Usually you see fungi in forests because its more moist and has more greens. A field is an open space and has too much sunlight, not many animals die in a field as in a forest its more common.

The plane of Earth's orbit around the Sun is called the: ?

Answers

Answer:

its called The Ecliptic.

Explanation:

The plane of Earth's orbit around the Sun is called the "ecliptic plane." The ecliptic plane is an imaginary flat plane that represents the average path traced by Earth as it orbits the Sun.

The Ecliptic plane serves as a reference plane for locating the positions of celestial objects in the sky, including the Sun, Moon, planets, and stars. The ecliptic plane is inclined at an angle of approximately 23.5 degrees with respect to Earth's equator, giving rise to the changing seasons as Earth orbits the Sun.

Therefore, the ecliptic plane represents the average path of Earth's orbit around the Sun and serves as a reference for understanding celestial positions and movements. Its tilt plays a vital role in determining Earth's seasons, and its alignment with other planets enables various astronomical phenomena.

Explain how vaccines work? Using the words virus, immune system, white blood cells, memory cells and vaccine

Answers

Vaccines work by training the immune system to recognize and combat pathogens, either viruses or bacteria. In order to do this, certain molecules from the pathogen need to be introduced into the body to trigger an immune response. These molecules are called antigens, and they’re present on all viruses and bacteria. Memory cells are then formed to remember the same pathogen for faster antibody production in future infections. Vaccinations increase the level of circulating antibodies against a certain antigen. Antibodies are produced by a type of white blood cell (lymphocyte) called B cells.

The correct answer is A. Fracture

Explanation:

A fracture occurs when a mineral, for example, calcite or quartz breaks in an irregular pattern. Fractures can occur due to multiple factors including pressure, temperature, among others. Additionally, fractures the term "fracture" differs from the term "cleavage" because in fractures breaks are irregular while in cleavage minerals break in a definite structure along the structural planes of the mineral. Thus, a fracture is the irregular break of a mineral.
