Answer: Research with embryonic stem cells may lead to new, more effective treatments for serious human ailments and alleviate the suffering of thousands of people.
Explanation:
Answer:
Voltage-gated Ca2+ channels
Explanation:
Modulation of Ca+2 channel Epinephrine also causes an increase in cAMP that stimulates PKA that is protein kinase A, which in turn phosphorylates the voltage-gated Ca+2 channel that is the L channel. This phosphorylation results in a protein conformational change that enchances the channels activity.
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.
The correct answer is:
A. leaves and dermal
Explanation:
The dermal tissue system protects the soft tissues of plants and handles interactions with the plants' surroundings. The epidermis is a dermal tissue that is usually a single layer of cells comprising the younger parts of a plant. It conceals a waxy layer named the cuticle that inhibits water loss. Plant parts that become woody no longer have dermal tissue as their outer layer because it is followed by periderm or cork. Just as our own covering assists to defend our bodies, the dermal layer of a plant has the same function.
