Answer:
Explanation:
There are two types of blood that flows through our bodies: oxygenated and deoxygenated. Oxygenated blood is the one that is pumped in the left side of the atrium in the heart. As its name tells us, is the one that is highly with oxygen and low in carbon dioxide. Normally a sample of an oxygenated blood will be very bright in red due to the amount of blood cells in it. Deoxygenated blood is the one that is pumped in the right side of the atrium in the heart. This blood is the one that is low in oxygen and high in carbon dioxide. It is also known as the venous blood. Normally a sample of a deoxygenated blood will be darker almost going on blue.
B) Meiosis-"a type of cell division that results in four daughter cells each with half the number of chromosomes of the parent cell, as in the production of gametes and plant spores." taken from google
A.)Well–developed vascular system
Vascular plants help maintain the water cycle. The property of these plants
enables them to carry out this function is their well-developed vascular system.
These type of plants are more evolved and developed than nonvascular plants
because of its specialized characteristics like xylem, which is a tissue that
is responsible for its framework and not only that, it is also has a greater mechanism
for water transference. Another is phloem, which is responsible for food
conduction.
Answer:
Change in chromatin structure-------Acetylation of histones facilitates transcription
Activity of transcription apparatus------Transcriptional activators increase promoter activity by interacting with the RNAPII holoenzyme
RNA processing---------Alternative splicing produces different transcripts from the same gene.
RNA interference-------A siRNA and the transcript it targets is transcribed from the same gene.
Initiation of translation-------Limited availability of initiation factors prevents translation of mRNA.
