Answer:
All animals are heterotrophic and have cells with no cell wall.
Explanation:
Since animals don't perform photosynthesis or any other process to make food, and don't contain a cell wall, that is what makes them different. Protist can be both autotrophic and heterotrophic and some can contain a cell wall, but most of them don't have cell walls.
Answer:
The inheritance pattern is of sex-linked
Explanation:
Sex-linked traits are traits that are controlled by genes which are located on the sex chromosomes. Superscripts of the X or Y chromosome are written as the alleles for sex-linked traits chromosome.
In this case, since all of the male offspring have long tail fins, and none of the females possess the trait. Mating two of the F1 fish fails to produce females with the trait. The sex-linked gene that is on the Y chromosome and is possessed only by males is the type of inheritance pattern that occurs here because after mating the two F1 fish no female produced possess the trait.
Answer:
4 chemicals
Explanation:
There are mainly 4 steps of gram staining.
1- crystal violet stain drained on the heat fixed slide.
2- then wash the slide and use iodine.
3- then wash the slide with water and use acetone as a decolorizer.
4- then use safranine as a counter stain.
So there are a total of 4 chemicals used named crystal violet, iodine, acetone, and safranine.
