The shapes and colors of radishes are controlled by two independent pairs of genes that show no dominance. The color may be red

(RR), white (WW), or purple (RW). The shape may be long (LL), round (OO), or oval (LO). Show a cross between a long, red radish and a round, white radish. Show the genotypes, the phenotypes, and the probabilities of the first generation.
___________ Genotype of the long, red radish

___________ Genotype of the round, white radish.

___________ What will be the genotype of all the offspring?

___________ What will be the phenotype of all the offspring?

Throw some loght on dichloroindophenol chemical and its function in photosynthesis
madam [21]

Answer:

Dichloroindophenol chemical act as electron acceptor in photosynthesis

Explanation:

DCPIP (2,6-dichlorophenol-indophenol) in general is a dye of blue color which reduces to become colorless and hence act as an electron acceptor in the light reactions of photosynthesis

It is used to measure the rate of photosynthesis, because its reduction leads to identification of reducing agent (Diphenylcarbazide) in plant  that is produced at the time of photosynthesis with in the chloroplasts.

Ordinary cell division produces two daughter cells that are genetically identical. This type of cell division is important for a
Ratling [72]

Answer:

C) production of sperm and eggs

Explanation:

Sperms and eggs are the male and female gametes respectively. Formation of sperms and egg cells require meiotic cell division. Meiosis in sperm mother cells and egg mother cells reduces the chromosome number of half in the sperms and eggs. Meiosis also adds new gene combinations in these gametes by the process of crossing over.  

Mitosis cannot reduce the chromosome number to half in the sperms and eggs. Absence of crossing over in mitosis leads to the formation of genetically identical progeny cells from mitosis.  

Hence, mitosis can not form sperms and egg cells.  If it does, the sperms and egg cells would not have genetic variations and there would be doubling of chromosome number with each round of sexual reproduction.

kolezko [41]

Answer:

Kinase-connected receptors or receptor tyro-sine kinases react for the most part to protein and chemical go between. A solitary trans membrane helix interfaces the extracellular restricting area to the intra-cellular space. e.g. insulin, development factors. The official of the ligand triggers the commencement of a few succession of occasions related with phosphorylation of proteins, this is called protein kinase course.  

For instance, the official of development hormone to the receptor in the plasma layer causes dimerization (by the actuation of Janus kinase 2, JAK2) of the receptor (conformation change) that bring about auto-phosphorylation of tyro-sine buildups. The official of SH2-space (src homology) protein (Grb-2) to the phosphorylated tyro-sine buildups invigorates cell development through a course of protein phosphorylation.  

a). RTKs are the trans-membrane receptors, which have a ligand restricting site on the extracellular area and tyro-sine authoritative on the intra-cellular space. In the event that it comes up short on the extracellular area, the ligand can't tie to the receptor site, so no cell reaction happens.  

b). On the off chance that it does not have the intra-cellular space, the ligand can tie to the receptor site, the receptor can't impart signs tot eh intra-cellular area because of the absence of intra-cellular space.
