B. White petal colour is a recessive trait.
Explanation:
In Mendelian genetics, the alleles depicted in small letters are recessive traits.
Since both alleles are same and in lower case they are homozygous recessive alleles for a white coloured petal gene.
The genotype of the trait will be tt because if it is crossed either with heterozygous or homozygous P alleles it will appear as tt to have phenotypic trait of white colour.
So the genotype will be tt.
Answer:Most gastropods, however, are useful to humans in that they help decompose dead plants and animals into substances that can be used by plants to manufacture new organic compounds
Explanation:
Two well-understood sncRNAs in eukaryotic cells are: microRNA and siRNA. SncRNAs are small non-coding RNAs with the main function in the regulation of different stages in gene expression. micro RNA are involved in RNA silencing (negative gene expression) and post-transcriptional regulation of gene expression(microRNA is complementary to a part of mRNA and can inhibit translation of that mRNA). siRNAs also <span>called</span> silencing RNA because of their possibility to inhibit translation by degrading mRNA after transcription.
Answer:
The correct answer is (c)
Explanation:
Episodic memories are an individual's memories of a <em>specific event.</em>
In this case, the subject remembers the situation, being in this class PSC001, when he learned what "word stem completion task" means, even he cannot remember what that means.
Episodic memories recollect <em>specific events, situations, and experiences</em>, and it involves the memory of the <em>location and time that the event occurred.</em>

Types of episodic memories:
There are four types of episodic memories: a) specific events; b) personal facts; c) general events; d) flashbulb memories
