Answer:
semi-permeable
Explanation:
passive transport is the movement of substances along the concentration gradient and no energy is utilized in it
DNA is made out of Deoxyribose sugar, phosphate, and nucleotides
Answer:
It is possible to compare the expression of homologous genes in the brain of <em>D. melanoganster</em> and humans, because the expression levels of conserved genes may be associated with the evolution of cognitive features such as complex learning and memory.
Explanation:
Model organisms can be used to understand the patterns and processes that affect human evolution. <em>Drosophila melanogaster </em>is a model organism that has been used to study expression patterns of conserved genes in the course of evolution. This model organism has also been used to develop genetic mutant lines in order to examine the role of genes evolutionarily conserved in animals, including those involved in neurocognitive development.
In genetic research, an experiment as the above described is framed in a research field named 'Behavioral Genetics', which is a discipline that studies how evolutionarily conserved gene networks may be associated with neurocognitive tasks during brain evolution.
People with central sleep apnea experience a complete cessation of respiratory activity for brief periods of time yet do not have frequent awakenings and do not tend to feel tired during the day.
<h3>What is sleep apnea?</h3>
Breathing regularly stops and starts during sleep, which is known as sleep apnea. People may have sleep apnea if they snore loudly and still feel exhausted after a full night's sleep.
These are the primary forms of sleep apnea:
The more prevalent type of obstructive sleep apnea happens when throat muscles relax.
Central sleep apnea, which develops when your brain fails to properly activate the breathing muscles,
When a person has both central and obstructive sleep apnea, it is known as complex sleep apnea syndrome, also called treatment-emergent sleep apnea.
