Give reason why wood is solid?
VARVARA [1.3K]

Solid wood is a term most commonly used to distinguish between ordinary lumber and engineered wood, but it also refers to structures that do not have hollow spaces. Engineered wood products are manufactured by binding together wood strands, fibers, or veneers with adhesives to form a composite material.

The correct order given below shows the changes that occurs in a mice population in response to changes in their environment:

  • The population of mice is in an environment with many black rocks
  • Mice with black for are more likely to survive and reproduce than mice with brown fur
  • After many generations, most of the mice in the population have black fur
  • A sandstorm covers most of the population's environment with brown sand
  • Mice with black fur are less likely to survive and reproduce than mice with brown fur
  • After many generations, most of the mice in the population have brown fur

<h3>What is the correct order for natural selection in the desert environment given?</h3>

Based on the process of natural selection due to envrionmental pressures, the population of the mice in the desert changes as follows before and after the environmental change:

  • The population of mice is in an environment with many black rocks
  • Mice with black for are more likely to survive and reproduce than mice with brown fur
  • After many generations, most of the mice in the population have black fur
  • A sandstorm covers most of the population's environment with brown sand
  • Mice with black fur are less likely to survive and reproduce than mice with brown fur
  • After many generations, most of the mice in the population have brown fur

Therefore, the correct order shows the changes that occurs in a mice population in response to changes in their environment.

A bubble of helium gas has a volume of 0.65 L near the bottom of a large
Flura [38]

Answer:

0.73L

Explanation:

The following data were obtained from the question :

V1 = 0.65 L

P1 = 3.4 atm

T1 = 19°C = 19 + 273 = 292K

V2 =?

P2 = 3.2 atm

T2 = 36°C = 36 + 273 = 309K

The bubble's volume near the top can be obtain as follows:

P1V1 /T1 = P2V2 /T2

3.4 x 0.65/292 = 3.2 x V2 /309

Cross multiply to express in linear form as shown below:

292 x 3.2 x V2 = 3.4 x 0.65 x 309

Divide both side by 292 x 3.2

V2 = (3.4 x 0.65 x 309) /(292 x 3.2)

V2 = 0.73L

Therefore, the bubble's volume near the top is 0.73L
