What about these molecules requires them to have this tetrahedron shape?
Answer:
There are four atoms required for having tetrahedron shape.
Explanation:
Tetrahedron shape molecule is made up of four atoms. The structure of tetrahedron shape molecule is just like pyramid. One atom is present at the top while the remaining three atoms attached to it at the bottom with bond angles of about 109.5°. So the structure of molecules only be possible if the molecule is made up of at least four atoms and have four unpaired electrons. Examples of such molecules are methane, water and ammonia.

A female rabbit can give birth to over 40 baby rabbits a year. Suppose all of her
offspring survived and reproduced, all of their offspring survived and
reproduced, and so on. If that happened, in only eight years the mass of rabbits
would exceed the mass of Earth! So, why aren't we overrun with rabbits? What
keeps the rabbit population in check?
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 disastersPredationIn 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.

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.

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

In a community, before biomass is widely used as an energy source, several experts, including an ecologist,are hired to provide specific information. The ecologist would most likely be asked about
Answer:
The ecologist provide information about the ecosystem.
Explanation:
The ecologist is a person who provide information about the relationship between organism and its environment. The ecologist tell the people about the benefits of plants that exist in our environment. Biomass is widely used as source of energy in a community which is gained from cutting of trees. The removal of trees causes damage to the whole ecosystem so the people of community used less biomass or other materials as a source of energy.
Which two classes make up the majority of crustaceans?
Answer:yes
Explanation:
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.
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.

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.

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