A block of metal has dimensions of 2.00 x 5.50 x 1.25 cm. It has a mass of 37.1 grams. What is its density?-512 g/cm3
-0.372 g/cm3
-2.69 g/cm3
-4.24 g/cm3

Answers

Answer:

                   Density  =  2.69 g.cm⁻³

Solution:

Data Given;

                   Density  =  ??

                   Mass  =  37.1 g  

                   Volume  =  2.0 cm × 5.5 cm × 1.25 cm  =  13.75 cm³

Formula Used;

                   Density  =  Mass ÷ Volume  

Putting values,

                   Density  =  37.1 g ÷ 13.75 cm³

                   Density  =  2.69 g.cm⁻³
2.69 is the correct answer

Which of the following is most likely an example of genetic drift resulting from the founder effect? a. The species’ physical habitat is limited. b. The population expresses a mix of dominant and recessive traits. c. The species occupies a small, specific niche. d. A population commonly expresses traits that are otherwise rare in the species.

Answers

An example of genetic drift resulting from the founder effect, of the available answers listed below, would most likely be a situation in which a population commonly expresses traits that are otherwise rare in the species. An example of this might be an animal with longer limbs than other members of the same species - there have been real-life examples of this studied with lizards.

The rainforest contains half of the Earth’s wildlife and at least two thirds of its plant species. It can hold great quantities of water and is very important to the planet’s water cycle. Rainforests remove vast amounts of CO2 from the atmosphere and replace it with oxygen. Which of the following statements best summarize the above information about rainforests?a.
The majority of the planet’s oxygen is generated from the rainforest.
b.
Two-thirds of all plants originated from the rainforest.
c.
The rainforest is a major catalyst for the planet’s water cycle.
d.
The rainforest is important to life as a whole on the planet.

Answers

The correct answer should be d. The rainforest is important to life as a whole on the planet. Without them the global warming phenomenon would skyrocket because of massive spikes of carbon dioxide that is man made. Without them the animal biomes would also get destroyed because suddenly thousands and thousands of species would be left without a home so you would disrupt nature. Without them the Earth would be ravaged by bad things.

Answer:

D) The rainforest is a major catalyst for the planets water cycle.

The Eurasian water milfoil is a nonnativespecies, which was once commonly sold as an
aquarium plant, and is now found growing in
many lakes in New York State. It has few
natural enemies, and grows rapidly, crowding
out many native species. This plant ruins fishing
areas and interferes with boating and other
water sports. This is an example of
(1) human consumption of finite resources
(2) an unintended consequence of adding an
organism to an ecosystem
(3) an abiotic factor having a negative effect on
an ecosystem
(4) the introduction of a species that has
increased the long-term biodiversity of an
ecosystem

Answers

The right answer for the question that is being asked and shown above is that: "(4) the introduction of a species that has increased the long-term biodiversity of an ecosystem." This plant ruins fishing areas and interferes with boating and other water sports. This is an example of the introduction of a species that has increased the long-term biodiversity of an ecosystem

Answer:

it would be (2) or B

Explanation:

Because if the plant is commonly sold as aquarium plants then they could have had an unintended consequence of adding an organism to an ecosystem.

Camel humps are an adaptation for _______.. a.. storing water. b.. regulating body heat. c.. carrying riders. d.. all of the above.

Answers

The correct answer is:

b regulating body heat.

Explanation:

Camels have humps on their backs as rooms to store fat. It is this fact that they live off when food and liquid are scarce. A well-fed camel in good shape has a firm, upright hump. After a long, exhausting wilderness journey the corresponding camel will have a hump that does floppy and bent over to one side.e. Concentrating body fat in their humps reduces heat-trapping.
