Answer:
Neural crest cell movements are inhibited.
Explanation:
Neural crest cells may be defined as the temporary group of cells that are unique for the chordata group. These cells arise from the embryonic ectoderm and give rise to future melanocytes.
Antibodies to fibronectin association is helpful to study the signalling factors. If these anitodies to fibronectin is shown in the embryonical stage. The neural crest migration is inhibited by its exposure to fibronectin and this might hinder the embryonic development.
Thus, the answer is neural crest cell movements are inhibited.
The answer is a neurologic
assessment by the stroke team should be performed within 25 minutes of
arrival. Neurologic assessment is the examination of sensory neuron and motor
responses, especially reflexes, to know whether the nervous system is compromised.
The following actions are undertaken:
<span>- </span>Review the patient's history, including past
medical history.
<span>- </span>Perform a physical exam.
<span>- </span>Begin last known well if not already done.
<span>- </span>Execute a neurological exam to assess patient's
status using the NIHSS or the Canadian Neurological Scale.
<span>-
</span><span>The CT scan should
be accomplished within 25 minutes from the patient's arrival in the Emergency Depatment
and should be read within 45 minutes.</span>
Answer:
Distinguishing between Similar Traits
Similar traits can be either homologous structures that share an embryonic origin or analogous structures that share a function.
LEARNING OBJECTIVES
Explain the difference between homologous and analogous structures
KEY TAKEAWAYSKey PointsOrganisms may be very closely related, even though they look quite different, due to a minor genetic change that caused a major morphological difference.Unrelated organisms may appear very similar because both organisms developed common adaptations that evolved within similar environmental conditions.To determine the phylogeny of an organism, scientists must determine whether a similarity is homologous or analogous.The advancement of DNA technology, the area of molecular systematics, describes the use of information on the molecular level, including DNA analysis.Key Termsanalogous: when similar similar physical features occur in organisms because of environmental constraints and not due to a close evolutionary relationshiphomologous: when similar physical features and genomes stem from developmental similarities that are based on evolutionphylogeny: the evolutionary history of an organismmolecular systematics: molecular phylogenetics is the analysis of hereditary molecular differences, mainly in DNA sequences, to gain information on an organism’s evolutionary relationships
Smoking, sitting too long, ......................... are examples of RISK FACTORS that offset the wellness benefits of fitness program.
Fitness program has many benefits that improve one's health status, but these benefits may be hindered from manifesting if one is indulging in some habits or eating some kind of foods that are not beneficial to one's health. Such unhealthy habits and foods are termed risk factors. And these risks factors may increase the probability of one having some types of diseases in the future. <span />
