Answer:
Explanation:
Knowledge it expected that an individual have the ability to recall some specific terms,facts,methods, processes, pattern, structure, or setting of a thing without necessarily understanding the concept.
Comprehension is the understanding an individual knows or get from what is being communicated and the ability to make use of the idea that is been communicated without seeing the full expression if it.
Comprehension is the explanation and understanding of knowledge i.e what is known and can be recalled.
Plants go through a process called photosynthesis where they take in carbon dioxide from the atmosphere (as well as water and sunlight), and they turn it into oxygen (so we can breathe) and glucose (sugar)!
Answer:
C) Through genomic imprinting, methylation regulates expression of the paternal copy of the gene in the brain.
Explanation:
The pattern of gene expression wherein either paternal or maternal gene is expressed in specific cells while the other one is prevented from expression is known as genomic imprinting.
In the given example, the maternal copy of the gene on chromosome 15 is expressed in brain cells while its paternal copy is not expressed in these cells. Hence, the pattern of expression of this gene is regulated through genome imprinting. One of the mechanism is methylation of cytidine residues of CpG islands of the DNA that are more frequently present within promoters of the genes.
When the cytidine residues of these sequences are methylated into 5-methylcytidine, the transcription factors do not bind to these promoters preventing the expression of these genes.
Hence, methylation of cytidine residue in CpG islands of the promoters of the gene present on chromosome 15 could have silenced its expression in brain cells.
Answer:
What?
Explanation:
I don't understand the question.
Which structure are you talking about??
This method of growing a new shrub is a type of asexual reproduction by fragmentation
Fragmentation is a type of asexual reproduction in which the parent organism is separated into many fragments, and each fragments will develop into complete matured individuals that are identical to the parent. Some animals and plants such as shrubs, ferns reproduce by fragmentation.
