Answer:
The atomic number that should be here, 57, is located at the bottom of the table in the row called the Lanthanides. Directly below the space in Row 6, in Row 7, is another empty space, which is filled by a row called the Actinides, also seen at the bottom of the chart.
Explanation:

Magnesium sulfate is an inorganic salt with the formula MgSO4(H2O)x where 0≤x≤7. It is often encountered as the heptahydrate sulfate mineral epsomite (MgSO4·7H2O), commonly called Epsom salt.
You can see my previous answer to this very same question on brainly.com/question/11374210.
The answer is: option D. Response to environment.
Explanation:
As explained, plants (organisms in general) respond to the stimulus provided by the environment.
Such behavior is named tropism. Tropism may be positive or negative.
When the plant's stem bends toward the window, it is showing positive phototropism, which means that the plant growth response to light such that the stems bend toward light, permiting the leaves to receive more light.
I also mention that while the plant's stems posses positive phototropism they posses negative gravitropism and the roots posses positive gravitropism.
Gravitropism is the response of the plant growth to gravity.
Stems grow away from gravity meaning that this is negative gravitropism, but roots grow toward gravity which is positive gravitropism
This question is incomplete because you lack the options. But it can be answered based on my knowledge.
Two types of mixture could be: homogeneous and heterogeneous
A mixture is a term that refers to the combination of two or more components joined but not chemically combined. Mixtures can be classified as follows:
- Homogeneous: Are characterized by having a uniform texture and appearance, their components are not distinguished.
- For example: water + grapes = wine
Homogeneous mixtures can be:
- Solutions: The mixtures formed are characterized by being formed with components that do not react chemically with each other, but that can modify their physical properties when they become part of the solution.
- For example: coffee + milk = Coffee
There are also Colloids, a type of mixture formed by particles of one or more substances that are dispersed in another substance called a dispersing medium.
- For example Gelatin powder + Water = Gelatin.
They are the intermediate mixtures between homogeneous and heterogeneous.
- Heterogeneous: Are mixtures in which it is possible to observe their components due to the discontinuity with the naked eye.
- For example Milk + cereal = Cereal
