Answer:
blood
Explanation:

Answer:
Genotype ratio= 1 RW: 1 WW
Phenotype ratio= 1 purple: 1 white
Explanation:
According to the given information, the gene for the color of radishes exhibits incomplete dominance and the heterozygous genotype gives purple color to the radishes. The genotype of the heterozygous parent plant with purple radishes would be "RW". A cross between a purple radish (RW) and a white radish (WW) would give progeny in following ratio=
Genotype ratio= 1 RW: 1 WW
Phenotype ratio= 1 purple: 1 white
They are all living, they grow, reproduce, excrete, respire and require nutrition. They all differ, the human, oak tree, sea weed and mushroom are multicellular( prokaryotes), and the rest are Unicellular( Eukaryotes). The sea weed& most bacterium produce their own food while the rest need to feed.
Answer: e. leaves have mesophyll tissue but roots do not.
Mesophyll tissues are found in the leaves of the plant, they are not found in roots. The primary role of mesophyll tissues is photosynthesis. Mesophyll tissues are made up of two types of cells.These include palisade parenchyma cells and spongy mesophyll cells. Palisade parenchyma cells are present beneath the upper epidermis of the leaf. They are elongated cells, which contains large number of chloroplast. The chloroplast helps in trapping sunlight energy.The spongy mesophyll cells are present beneath the palisade parenchyma cells and above the lower epidermis of the leaf. These are loosely arranged spherical cells, which consists of empty spaces or large pores and few chloroplast. The empty spaces or large pores helps in gas exchange between the internal and external environment of leaf.
The sympathetic nervous system (SNS) is the division of the autonomic nervous system arouses the body and mobilizes its energy in stressful situations.
