Answer:

A) the mass of the reactants is the same as the mass of the product

I guess

Explanation:

the law of conservation of mass stats that Mass of reactant is always equal to the Mass of the product

Other Causes of Extinction

In addition to habitat destruction, other human-caused problems are also threatening many species. These include issues associated with climate change, pollution, and over-population.

Climax Community

A climax community is the end result of ecological succession. The climax community is a stable balance of all organisms in an ecosystem, and will remain stable unless a disaster strikes.

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 they change that 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.

Human Activity

It's important to note that human activity has the greatest impact on the amount and quality of wildlife habitat in many areas of the world. Wildlife habitat can be destroyed or its quality diminished as a result of urban growth, agricultural practices, pollution, or habitat destruction.

People can also have a positive impact on wildlife populations through improvement and protection of habitat or ecosystems. Planting trees and shrubs and providing sources of food and water in individual yards is one way people can help wildlife.

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:

The cell membrane's main trait is its selective permeability, which means that it allows some substances to cross it easily, but not others. Small molecules that are nonpolar (have no charge) can cross the membrane easily through diffusion, but ions (charged molecules) and larger molecules typically cannot.

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.

The answer for the question is A

Answer:Light bounces off of the mirror and then appears to come from behind the mirror.

Explanation:Plane mirrors form images that are virtual, upright and the same size and shape as the object it is reflecting.

When rays of light from the object hits a plane mirror they bounces off the mirror,that is they undergo reflection, and appear to originate from behind the mirror, resulting to the formation of a virtual image.

The image formed appears to be behind the plane in which the mirror lies. A virtual image is an image that is formed at a location from which the rays of light appear to come from. The image can not be formed on a screen..

When a species becomes extinct all its genetic heritage is lost. Here The introduction of a toxic pollutant to the entire range of the species causes the extinction of the species and also the climate change. The correct options are A and D.

The process of evolution which leads to the disappearance of a population or species is defined as the extinction. The species evolve into new species in order ton adapt to the environmental changes in the genetic heritage.

The pollution from industries and vehicles will cause a drastic change in the level of oxygen in the atmosphere as well as water. This is responsible for the extinction of the most of the aquatic as well as terrestrial species.

Climate change is also an another factor which cause the destruction of the organisms. Many organisms are died due to global warming.

Thus the correct options are A and D.
