How would removing your umbrella in a rainstorm affect your ability to stay dry? The definition of a keystone species is a species that has a crucial role in an ecosystem. Removing one gear from a clock would stop the clock from working. Removing/changing a major contributer to a balance and natural ecosystem can potentially collapse the entire system altogether.

Answer:

The keystone species are those species that plays a very important role in the functioning of an ecosystem. They are those species in which a large number of organisms are directly dependent on. These species can be both plants and animals. In the absence of this species, the ecosystem will be in disequilibrium, affecting the other organisms that exist in the ecosystem. For example, Wolf and Jaguar.

The keystone species are predators that prevents a herbivorous species from wiping out a governing species of plants. If the number of prey is low, then these keystone predators could be even less in number but still will be powerful.

Many of the scientists have divided these keystone species into 3 types. They are as follows-

(1) Predators

(2) Ecosystem engineers

(3) Mutualists

Which of the following is not a way that sexual reproduction increases genetic diversity?
cricket20 [7]

Answer:

Combined parenting leads to faster reproduction

Explanation:

Genetic diversity or variations in the physical appearance of organisms is caused by genetic or environmental factors. Reproduction brings about variation through gamete formation, fertilization and mutations.

During prophase 1 of meiosis, homologous chromosomes pair to form bivalents. The crossing over at the chiasmata results in new gene combination and variations.

Fertilization permits parental genes to be brought together. This causes variations in members of the same family.

Mutation is the spontaneous change in genetic make-up. These changes may be inherited by offspring bringing variations. However, combining parenting does not increase genetic diversity.

The table below shows the dimensions of two colored cubes.
Lelechka [254]

Answer: The correct answer is black because the product of its side and mass is lower.

Explanation: Density of a substance is defined as the mount of matter that can be stored in a given volume.

Mathematically,

Density=\frac{Mass}{volume}

As, density is inversely proportional to the volume of the substance.

The substance will be more denser if it has less volume and it will be less denser if the volume is more.

We are given two cubes having different sides.

Volume of the cube is calculated by using the formula:

V=a^3

where, a = side of the cube.

Black: The side of this cube is 2 and volume will be = 2^3=8cm^3

Yellow: The side of this cube is 3 and volume will be = 3^3=27cm^3


As, the volume of black cube is less. So, this cube will be more denser.

Density of black cube: \frac{48}{8}=6g/cm^3

Density of Yellow Cube: \frac{135}{27}=5g/cm^3

Hence, black cube will be more denser  because the product of its side and mass is lower.
