For the first 2 rows it’s going to be the dominant phenotype. So “purple flowers” for the 1st and 2nd row and white flowers for the last one. For the first row on #17 it’s going to be “FF “and “ff” for the 2nd. Tongue roller is “TT” and non tongue roller is “tt.”
Answer:
Water sample showing pink/purple color is an error.
Explanation:
Biuret is a blue color reagent that changes its color to pink/purple whenever it detects protein in a sample. Water don't contain proteins so it should not show pink/purple color instead it should maintain the blue color. Food items generally contain proteins so it show pink/purple color but it showed blue color.
Error might have caused by wrong marking of the samples, test tube marked with Water might contain a mystery food while Mystery food tube might contain water.
True ..In animals, the female mitotic sequence produces only one ovum; the other three haploid cells become "polar bodies".
Answer: Option D) Cells in multicellular organisms are specialized to perform certain functions.
Explanation:
Multicellular organisms include humans, reptiles, birds etc. While unicellular organisms include amoeba, paramecium etc
From the examples given, the cells of multicellular organisms are specialized in function in that:
- cells that perform similar functions are put together as tissues, organs or system e.g digestive system consists of the similar cells that help to break down food into pieces
On the other hand, unicellular organisms possess just one cell that do all the functions.
Thus, the difference between both is that cells in multicellular organisms are specialized to perform certain functions.
