Explanation:

The answer for the question is A

Answer:

D created; destroyed; conserved

For a chemical reaction in a closed system, mass cannot be created or destroyed. We can say that throughout the reaction, mass is conserved.

A closed system is a thermodynamic term. It can also be said as thermodynamic system. In a thermodynamic closed system, there is no exchange of mass or energy with the outer environment.

Thus, the correct option is D. created; destroyed; conserved.

Answer:

A medium is a substance that allows any material to travel through it.

Explanation:

The liquid is base. A base is a type of chemical that releases hydroxide (OH-) ions, receives protons, or donates electrons in an aqueous solution.

Bases have a few distinguishing characteristics that can be used to recognize them.  They can taste harsh, react with acids to generate salts, have a tendency to be slick to the touch (like soap), and can catalyze some processes.

Arrhenius bases, Bronsted-Lowry bases, and Lewis bases are some examples of bases.  The French scientist Louis Lémery coined the term "base" in 1717. Lémery used the term to refer to Paracelsus' alchemical notion of a "matrix" According to Paracelsus, natural salts form when a matrix and a universal acid interact.

Although Lémery may have coined the term "base" first, Guillaume-François Rouelle is generally recognized as the father of modern usage.

Answer:

Other Causes of Extinction in addition to habitat destruction, other human-caused probelms are also threatening many species. These include issues associated with climate change, pollution, and over-population.

Invasive Species as we have learned earlier in the unit, invasive or non-native species can also change an ecosystem. When invasive species enter an ecosystem's dynamic and cause a disruption to the flow.

Habitat Destruction Your habitat can be altered, and you can easily adapt. Most people live in a few different places and go to a number of different schools throughout their life. But a plant or animal may not be able to adapt to a changed habitat.

Humans often destroy the habitats of other organisms. Habitat destruction can cause the extinction of species.

Extinction is the complete disappearance of a species. Once a species is extinct, it can never recover.

Explanation:

Both pitcher plant and king penguin use their physical adaptation to catch pray. The curved beak of the penguin helps them easily catch fish from snow similarly pitcher plant has the cup like structure to capture pray. Hence, option A is correct.

Pitfall traps, a prey-trapping mechanism with a deep hollow filled with digesting fluid, are modified leaves on a kind of carnivorous plants known as pitcher plants. Specialized leaves are used to create the traps in what are known as "genuine" pitcher plants. Using nectar, the plants draw in and suffocate their victim.

Flying, flying, or crawling insects that are out foraging are drawn to the hollow created by the cupped leaf by visual cues such nectar and anthocyanin colors.

Insects fall into the trap because the pitcher  is slippery after being saturated by dew or nectar. To aid in preventing escape, the walls of the pitfall may be covered in waxy scales, protruding aldehyde crystals, cuticular folds, downward-pointing hairs, or lunate cells that originate from guard cells.

The sharp curved beak of penguin helps to easily catch their pray. Therefore, option A is correct.

Answer:

volume of cube = l^3

=2cm^3

=8cm^3

now,

mass=(9.7÷1000)kg

=0.0097kg

volume=8cm^3÷100=0.08

we know that,

density=mass/volume

= (0.0097/0.08)kg/m^3

= 0.12125kg/m^3

Explanation:

the formula to calculate volume of cube is l^3 so here we find the volume of cube using this formula and then we convert gram into kilogram then convert cm into m then by applying the formula of density we find it density

A 2 cm cube made of acrylic has a mass of 9.7 g. The density of the acrylic is 0.12125 kg m3

Density is the mass of per unit volume.

[tex]Volume of cube = l^3\\=2cm^3\\=8cm^3[/tex]

mass 9.7 kg, converted into kilograms = 0.0097kg

[tex]Volume \;= \dfrac{8cm^3}{100} = 0.08[/tex]

Calculating the density

[tex]Density = \dfrac{mass}{volume} \\\\\dfrac{0.0097}{0.08} = 0.12125\;kg\;m^3[/tex]

Thus, the density of the acrylic is 0.12125 kg m^3.
