True/false, if false explain why
An S-haplotype is a type of stigma with papilla cells that adhere with only one type of pollen.
Answer:
True.
Reason: S-Haplotype cells that adhere with only one type of pollen. Because these genes exhibiting stronger signature of purifying -selection and positive selection and it also helps to determine the genetic sex .

True/false, if false explain why A pollen tube is compatible with a pistil if the pollen tube has the same S-haplotype as the cells of the pistil.
True/false, if false explain why Meristemoid cells secrete EPFL proteins that signal adjacent protodermal cells to NOT differentiate into meristemoid cells.
True/false, if false explain why Synergids secrete chemoattractants called LUREs, which guide pollen tubes to embryo sacs.
true or false, please give explaination TRUE/FALSE. Explain why the answer is true or false. 3) True or False: Assume that a species has a diploid chromosome number of 24. The term applied to an individual with 25 chromosomes would be triploid. 4) True or False: Inversions suppress crossing over by providing a chemical imbalance because of breakpoints within certain genes. e or False: Individuals with familial Down syndrome are trisomic and have 47 chromosomes. 6) True or False: An...
True or False. If true, explain why. If False, gve a counterexample. If Σοη6" is convergent, Cnb is convergent, then Σ on(-2)" is convergent. True or False. If true, explain why.

Explain why these are true or false. A single skin cell in a human female has: (select all) a) DNA from her mother and father (true) b) different DNA content than her liver cells (false) c) different protein content than her liver cells (true) d) different DNA content than her egg cells (true)
Problem 5. True/False. (Is the statement true or false? Explain why.). 1. Both Northern blot and in situ hybridization techniques start with extracting and purifying all transcripts from an organism, an organ, or a group of cells. 2. Both Northern and Western blot techniques require preparation of a labeled DNA probe that is complementary to the transcript of a gene that you study
TRUE or FALSE and Explain why:
Please answer true or false. If false, explain why.
