Answer:
Metric ruler
Explanation:
You need to measure length, which is exactly what a ruler measures. The other option measure other things, like liquids or temperature.
Answer:
Phenotypic ratio = 1 Red : 1 Pink
Explanation:
This phenomenon exhited by the gene coding for flower colour in four o'clock plants is called INCOMPLETE DOMINANCE i.e. the red flower allele (R) is not completely dominant over the white flower allele (r), hence, a third intermediate pink phenotype (Rr) is formed in an heterozygous state. The red and white flowers will only be expressed in a RR and rr genotypes respectively.
In a cross between a red-flowered 4 o'clock plant (RR) and a pink-flowered 4 o'clock plant (Rr), the gametes:
R and R will be produced by the red-flowered plant while gamete R and r will be produced by the pink-flowered plant. Using this gamete in a punnet square, one will have four possible offsprings in which two will be phenotypically red-flowered (RR) and two phenotypically pink-flowered (Rr). i.e. 2RR:2Rr
Hence, the phenotypic ratio is 1:1 Red to Pink flower
Answer:
Moss
Explanation:
Bio means alive, and tic means with, so biotic means with life. Moss is the correct answer because it shows sings of life, such as reproducing, and showing responses to change. Water, rocks, and sunlight are not alive because they show none of the signs of life.
Answer: All are multicellular and eukaryotes.
Answer: Five
Explanation:
Mitosis is one of the two types of cell division alongside meiosis that occurs in living cells (although mitosis occur in only somatic or body cells).
Mitosis occurs in five stages, which are:
- Interphase
- Prophase
- Metaphase
- Anaphase
- Telophase
At the end of the five stages, a parent cell with diploid number give rise to two daughter cells with diploid number as well.
