Answer: If the electronegativity difference between the atoms is greater than 2.0, the bond is ionic. Ionic compounds are extremely polar molecules. Examples of polar molecules include: Water - H2O.
Hope this helps!!! Good luck!!! ;)
immune system refers to any a ability of the body to resist Invasion by a disease causing organisms
Answer:
Immune system
Explanation:
OB. A smaller ion
OC. A covalent bond
OD. An ionic compound
Answer:D. An ionic compound
Explanation:
An ionic compound by a complete transfer of valence electrons from an atom of a metal to an atom of a non metal so that both can attain a stable duplet or octet structure of noble gases. Potassium has 19 electrons with one valence electron while chlorine has 17 electrons with 7 valence electrons. Potassium will transfer its valence electron to chlorine atom, resulting in potassium having one positive charge and chlorine have one negative charge with both attaining a noble octet structure of noble gases. The compound formed is an ionic compound because it involves a positively charged potassium ion and a negatively charged chloride ion.
Answer:
OD.
Explanation:
BECAUSE THE BOND WAS IONIC AND IT'S FORMING A COMPOUND OF ELEMENTS SORRY 4 THE CAPS LOCK THE BUTTON'S JAMMED
Blue wave helps astronomers to determine the hottest stars.
Managing technological requirements, vetting service providers, assessing proposals, and tracking continuous solution optimization can be costly, time-consuming, and difficult.
The Bluewave Technology Lifecycle Management Approach is a client-focused approach to assessing, sourcing, managing, and supporting technology solutions that can encompass a wide range of suppliers from dozens of screened, approved possibilities.
When sunlight enters the atmosphere of Earth, all the gases and airborne particles scatter it in all directions. Because blue light travels as shorter, smaller waves than the other hues, it scatters more than the other colors.
Therefore, Blue wave helps astronomers to determine the hottest stars.
To learn more about blue waves, refer to the link:

Answer:
Explanation:
In the electromagnetic spectrum are plenty of different waves that change their properties according with their length, energy, frequency. In this case, the hottest stars are the blue ones, because this means that they are spreading waves with a major frequency and, for instance, major energy, which means major hot.
B) diffusion
C) osmosis
D) facilitated diffusion
Find out more information about "facilitated diffusion" :
Answer:
In cells, some molecules can move down their concentration gradients by crossing the lipid portion of the membrane directly, while others must pass through membrane proteins in a process called facilitated diffusion.
Explanation: so it is
D :)
The process that enables babyscorpions to develop various kinds of body parts from a single zygote is cell differentiation. The correct option is 4.
The process by which dividingcells change their functional or phenotypical type is known as cell differentiation.
All cells, it is assumed, derive from stemcells and acquire their functions as they mature. Cellular composition is frequently represented as a hierarchical scheme, with stem cells at the top.
Cell differentiation refers to the process by which stem cells become more specialized. Cell differentiation is important because it creates diversity in life on Earth, diversity within our bodies' cells, and allows cells to form unique structures that fit their individualizedfunctions.
Cell differentiation is the process by which baby scorpions develop various body parts from a single zygote.
Thus, the correct option is 4.
