if you had a block square that weighed 5.00 grams what would be the length of each side

Answers

Answer:

[tex]l = 0.793[/tex] cm

Explanation:

Let us assume the density of block square [tex]10[/tex] g/cm³

As we know

Volume = [tex]\frac{Mass}{Density}[/tex]

Thus Volume of this block is equal to [tex]\frac{5}{10} = 0.5[/tex]

As we know volume of square block of side of length "l" is equal to [tex]l^3[/tex]

[tex]l^3 = 0.5[/tex]

[tex]l = 0.793[/tex] cm

Which best describes the effect of a ecosystem when populations of white-tailed deer are overhunted by people in an area?

A. It disrupts the balance between predators and prey
B. It decreases the amount of producers
C. It directly increases the population of decomposers
D. It decreases competition for food among carnivores

Answers

Answer:

A. It disrupts the balance between predators and prey

Explanation:

The effect on the ecosystem when populations of white  - tailed deer are overhunted is that it disrupts the balance between predators and prey within the ecosystem.

The whited - tailed deer is the usually the prey. The carnivores are the cats and other flesh eating animals. When the deer is over-hunted, there are more predators compared to prey. This leads to a serious imbalance and a high level of competition for the scarce prey.

what do igneous rocks become when they break down and settle into layers?

Answers

Answer:

Sedimentary rocks

Explanation:

Igneous rocks will become sedimentary rocks when they break down and settle into layers .

Igneous rocks are rocks that are formed by the cooling and solidification of magma within or on the earth crust.

When agents of weathering and denudation forces acts on a rock body, they break them down producing sediments in the process.

Sediments are transported into depositional basins where they are laid down and cemented together. This in turn forms sedimentary rocks. The break down and settling of sediments leads to the formation of sedimentary rocks.

Osmium metal, the densest element, has a density of 22.6 g/mL, while hydrogen, the least dense element, has a density of 8.99 e-5 g/mL. Calculate the volume occupied by 1.00 g of each element. How many times more dense is osmium than hydrogen?

Answers

Answer:

1. Volume of osmium = 0.044 mL

2. Volume of Hydrogen = 11123.47 mL

3. Osmium is 251390 times denser than hydrogen

Explanation:

From the question given above, the following data were obtained:

Density of osmium = 22.6 g/mL

Density of Hydrogen = 8.99×10¯⁵ g/mL

Mass of osmium = 1 g

Mass of Hydrogen = 1 g

1. Determination of the Volume of osmium.

Density of osmium = 22.6 g/mL

Mass of osmium = 1 g

Volume of osmium =?

Density = mass /volume

22.6 = 1 / volume

Cross multiply

22.6 × volume = 1

Divide both side by 22.6

Volume = 1 / 22.6

Volume of osmium = 0.044 mL

2. Determination of the Volume of Hydrogen.

Density of osmium = 8.99×10¯⁵ g/mL

Mass of osmium = 1 g

Volume of osmium =?

Density = mass /volume

8.99×10¯⁵ = 1 / volume

Cross multiply

8.99×10¯⁵ × volume = 1

Divide both side by 8.99×10¯⁵

Volume = 1 / 8.99×10¯⁵

Volume of Hydrogen = 11123.47 mL

3. Determination of the number of times osmium is denser than hydrogen.

Density of osmium (Dₒ) = 22.6 g/mL

Density of Hydrogen (Dₕ) = 8.99×10¯⁵ g/mL

Dₒ / Dₕ = 22.6 / 8.99×10¯⁵

Dₒ / Dₕ = 251390

Cross multiply

Dₒ = 251390 × Dₕ

Thus, osmium is 251390 times denser than hydrogen.

To locate objects in their environments, bats in flight and porpoises under water both use ultrasound waves with frequencies that are beyond human hearing.

The bat would hear its echo first because sound travels faster in air than in water. O The porpoise would hear its echo first because sound travels faster in water than in air. O The bat would hear its echo first because the frequency of sound waves is greater in air than in water 0 The porpoise would hear its echo first because the frequency of sound waves is greater in water than in air.​

For species that reproduce asexually, all their offspring are
A. genetically identical
B. genetically different
C. almost identical
D. slightly different​

Answers

Answer:

A. genetically identical

Explanation:

Asexual reproduction produces offspring that are genetically identical to the parent because the offspring are all clones of the original parent. A single individual can produce offspring asexually and large numbers of offspring can be produced quickly

All the offspring that are produced in the process are genetically identical.

When we talk about this mode of reproduction, we talk about a mode of reproduction in which an organism reproduces without the fusion of gametes. This occurs essentially by cell division.

When this occur, there is no crossing of genetic material as such, all the offspring that are produced in the process are genetically identical.
