A decrease in dissolved oxygen.
This is because oxygen is a byproduct of photosynthesis. If the plants are in water, some of the oxygen they produce will become dissolved in it. Without those plants, you have less dissolved oxygen.
Answer: because the structure of their cell wall is unable to retain the crystal violet stain
Explanation:
Due to differences in the thickness of a peptidoglycan layer in the cell membrane between Gram-positive and Gram-negative bacteria, Gram-positive bacteria (with a thicker peptidoglycan layer) retain crystal violet stain during the decolorization process, while Gram-negative bacteria lose the crystal violet stain
1) The environment of nebulas attract the dust and gas together and forms the necessary components of a star.
2) It is created by comparing different stars by their luminosity and color.
The statements describe how traits are inherited are:
- Traits are inherited when genes are passed from parents to offspring.
- An offspring can receive different alleles or the same alleles from each parent.
<h3>What are traits?</h3>
Dominant traits are always expressed when the connected allele is dominant, even if only one copy exists.
Recessive traits are expressed only if both the connected alleles are recessive.
Polygenetic traits are basically the traits that are controlled by two or more genes.
Thus, option "3 and 5" is correct.
