When a petal is plucked from a flower, it will not remain alive for very long. It will soon start to decompose.
Explanation:
To understand this, we need to go back to the act of plucking the flower as such from the plant. The moment a flower is plucked from a plant, it stops receiving any further nutrition from the plant. Whatever nutrients were present in the flower at the time of plucking it will continue to keep it alive and once those nutrients are used up, the flower will start to decompose.
In this case, since the petal is plucked from a flower which already was surviving on limited nutrients, it will decompose very quickly.
According to the characteristics of life, it cannot be considered dead at the time it's plucked. It <u>continues to live, but for a very brief time</u>.
Answer:
Vascular Tissues
Explanation:
Angiosperms higher flowering plants it is most diverse group in a plant kingdom nearly 300,000 species of flowering plants are found under this kingdom.The angiosperms have specialised cells and tissues that carry out their metabolic functions and evolved vascular tissues (xylem and phloem) that translocate the water and nutrient to all parts of the plant. They are terrestrial, root system absorbs water and mineral from the soil. the shoot system supports and leaves involved in the process of photosynthesis
Which mode of inheritance produces heterozygotes with phenotypes that differ from either homozygote but typically more closely resembles one homozygous phenotype than the other?"
A) complete dominance
B) incomplete dominance
C) codominance
D) epistasis
E) incomplete penetrance
Answer:
B) incomplete dominance
Explanation:
Incomplete dominance occurs when the dominant allele of a gene is not able to mask the expression of the recessive allele completely. This results in the expression of a phenotype in the heterozygous genotypes that differ from both homozygous genotypes. However, the phenotype of the heterozygote is closer to one of the homozygous genotypes.
For example, the petal color in four o'clock plant is controlled by a gene with two alleles R and r. Here, the "R" allele can not produce enough pigment in heterozygous conditions to completely mask the expression of the "r" allele and the phenotype of the "Rr" plant is "pink". On the other hand, the phenotype of "RR" plant is red while that of the "rr" plant is "white".

1. What is the blending theory of inheritance? Why did Mendel question this theory? The theory is that offspring have a blend, or mix, of the characteristics of their.
