In an ionic compound, the attraction between actions and _________ hold the compound together

Nady [450]

Answer:
The correct option in blank is anion.

Explanation:
Ionic compound is formed by the transfer of electron from one atom to another atom. When an electropositve atom lose an electron it form cation, whereas as anion is formed when an atom gain an electron. These actions and anions then attract each other and form an ionic compound.
I hope it will help you.

Example:
The formation of NaCl is best example of ionic compound. Na has one electron in its outer most shell which can easily be removed to form Na+, while Cl has seven electron in its outer most shell so it can easily gain an electron lost by Na to form Cl-. Then these ions attract each other and form NaCl as shown in the figure.

What group of organisms are responsible for capturing energy within ecosystems

Marina86 [1]

The type of organisms that take energy by eating up other organisms in an ecosystem are called 'CONSUMERS'. Now these consumers are further divided into three major classes:

1. Primary consumers: this type of consumers feed directly from the producers (plants) and they only eat grass, leaves, vegetables, etc. Such animals are also called herbivores. Example: rabbit

2. Secondary consumers: these are the animals that eat up primary consumers (animals that feed only on plants). These animals are called carnivores. Example: snake

3. Tertiary consumers: animals that eat carnivores which eats a herbivore are called tertiary consumers. They can be completely carnivore or omnivore (who feed on animals and plants both). Example: humans (they feed on animals and plants both)

Bill has a perfect cube of an unknown substance. The density of the substance is 3.0 g/cm. He

Gwar [14]

The volume of the cube of unknown substance is $27\ cm^3$ . The length of one side of the cube is 9 cm

Explanation:

As per the formula of mass and density, Mass / Density equals to volume. Therefore as the mass of the cube was given to be 81 g and the density of the cube is known to be 3.0 g/ $\mathrm{cm}^{3}$ ,, to help Bill find out the volume. It is the ratio of mass and density and can be calculated as

$\text {volume}=\frac{\text {mass}}{\text {density}}=\frac{81 g}{3 g / \mathrm{cm}^{3}}=27 \mathrm{cm}^{3}$

As it is a cube, the volume is product of length, breadth, and height. Here, all sides are same as it is the cube.

$volume= length \times breadth \times height$

$27=3 l$

$length of cube's one side, l=\frac{27}{3}=9 \mathrm{cm}$

Which component of a homeostatic system compares sensory information to a target value?

Katen [24]

Answer:

Integrator compares sensory information to a target value.

Explanation:

Integrator is responsible for sending 'instructions to an effector' based on 'sensory information' which eventually give responses.

These effectors execute the necessary changes required to adjust with the environment. Integrator act as the control centers.

Integrators send signals to the effectors after comparing the variables or changes at a definite set point.

However, its function mechanism is 'dependent on the feedback loop'.

Productivity increases when A. outputs decrease while inputs remain the same. B. inputs increase while outputs remain the same.

Evgesh-ka [11]

Answer:

Explanation:

For productivity to increase, it require an increase in the input which has to be directly proportional to an increase in the output
