They would have a competitive relationship since they are in the same class
Answer:
The correct answer would be - strontium, magnesium, beryllium.
Explanation:
As we know that the number of the same valence electrons is most likely to exhibit similar physical and chemical properties so the elements of the particular group in the periodic table have a similar number of physical and chemical properties and a similar number of the valence electrons.
For example, group 2 elements are known as alkaline earth metals, and strontium, magnesium, beryllium, and calcium are the same group elements thus, they have the same chemical and physical properties as they have 2 valence electrons.
Answer:
A binary star is a star system consisting of two stars orbiting around their common barycenter. Systems of two or more stars are called multiple star systems. These systems, especially when more distant, often appear to the unaided eye as a single point of light, and are then revealed as multiple by other means.
How to cut what open? and a mask.
<h3><u>Answer;</u></h3>
-Frustule
-Autotrophic
-Heterotrophic
The external coverings of diatoms are made up of<u> frustule </u>, while slime molds have cell walls containing cellulose . Diatoms are <u>autotrophic </u>because they make food through photosynthesis, while slime molds are <u>heterotrophic</u> because they eat decaying plant matter.
<h3><u>Explanation</u>;</h3>
- <em><u>Diatoms are tiny single-celled algae that are covered with glass like shells made of silica. Slime molds on the other hand are fungus-like protists that re heterotrophic like protozoa in the kingdom protista</u></em>.
Diatoms and slime molds differ in a number of ways which include;
- <em><u>Diatoms are food producer or autotrophs while the slime are consumers or heterotrophs and depend on the product produced by the primary producer such as plants, diatoms etc.</u></em>
- <em><u>Diatom posses photosynthesis while the slime mold lack that.</u></em>
- Slime molds are fungus like protists and have both plant and animal like characteristics while diatoms have only plant like characteristics.
- <em><u>The external coverings of diatoms are made up of frustule, while slime molds have cell walls containing cellulose</u></em>
