Answer:
Gamma-rays are a form of electromagnetic radiation, as are radio waves, infrared radiation, ultraviolet radiation, X-rays and microwaves. Gamma-rays can be used to treat cancer, and gamma-ray bursts are studied by astronomers.

Hope this helped Mark BRAINLIEST!!!
1. Fact: A dead organism is still an organic being.
Evidence: Non-living things differentiate from living beings due to differences in organic and non-organic chemical compounds. On top of this, non-living things were never alive in the first place.
2. Fact: The Linnaeus system, although still recognized as the perfect class system, has changed.
Evidence: Initially, Kingdom was the highest class in the system; however, later on, scientists introduced a class above this- the Domain.
3. Fact: The tiger and goldfish are not closely related.
Evidence: Although all living things share common ancestors from billions of years ago, they branched off and continued to do so since then. The only relation these two organisms share is distant DNA patterns.
4. An organism's kingdom is no longer only based on physical appearance.
Evidence: Although before the rise of genetics and evolutionary sciences this may have been the case, it isn't anymore. We now have the ability to analyze DNA, as well as actually pick apart what makes the organism what it is.
5. Mammals are indeed in the same domain as plants.
Evidence: All plants, fungi, protists, and animals posses eukaryotic cells; therefore placing them in the same domain.
Answer:
Metal oxide + acid —> salt + water
Explanation:
<u>Answer:</u> The correct answer is 4, 2.
<u>Explanation:</u>
Hybridization is calculated by using the formula:
where,
V = number of valence electrons present in central atom
N = number of monovalent atoms bonded to central atom
C = charge of cation
A = charge of anion
It is given that the hybridization of a molecule is , this means that the number of electron pairs are 6. The molecular geometry of the molecule having electron pairs as 6 is octahederal.
If the molecular geometry of the molecule is square pyramidal, then it would acquire 4 electron pairs as the bonding groups and the rest pairs would be considered as lone pairs.
Hence, the correct answer is 4, 2.
The answer is 28% as u find the molar mass of cu and divide it by the total molar mass
