Answer: Option C " S. cerevisiae"
Explanation: Saccharomyces cerevisiae can be used as a model system for the fundamental cellular process related to eukaryotic organism.
The reason it is being used for the study of eukaryotic cells is as follows:
1- It has high multiplication rate.
2- As per the study, more than 60% of the functional gene is known.
3- 30% of the human genes has the same homology to this yeast
Hence, S. cerevisiae is used as a model organism for studying eukaryotic cells.
If a patient's arterial blood gas indicates that her PaCO2 is 55 mm hg, then she is in the state of hypo-ventilating.
PaCO2 and ventilation are inversely correlated. A high PaCO2 hence indicates poor ventilation. Due to the opposite effects of ventilation, PAO2 and PACO2 are inversely connected. Increased PAO2 and decreased PACO2 are the outcomes of hyperventilation (PACO2 40 mmHg). Decreased PAO2 and hypoxemia result from hypoventilation (PACO2 40 mmHg).
The amount of carbon dioxide in arterial or venous blood is measured by the partial pressure of carbon dioxide (PCO2). It frequently acts as a sign of adequate alveolar ventilation in the lungs. Normally, the value of PCO2 falls between the range of 35 to 45 mmHg, or 4.7 to 6.0 kPa, under normal physiological conditions. Although an arterial blood gas is typically used to measure PCO2, there are additional approaches, such as peripheral venous, central venous, or mixed venous sampling.

Answer:
A. sharing electrons
Explanation:
A covalent bond consists of the simultaneous attraction of two nuclei for one or more pairs of electrons.
Answer:
Effective injury prevention methods include the use of childproof caps on medications and household poisons, age-appropriate restraints in motor vehicles (i.e., car seats, booster seats, seat belts), bicycle helmets, and a four-sided fence with a locked gate around residential swimming pools
Explanation:
Injuries are the leading cause of death and disability for young children. Young children are at higher risk of injuries overall, and certain injuries are more probable at different ages. Toddlers are most susceptible to poisoning, pre-schoolers to drowning, and school-aged children to pedestrian accidents. Children are more likely to be injured when they are not under appropriate adult supervision.
The vast majority of childhood injuries are preventable. Child care providers need to take specific steps to prevent injury in the child care setting. The following are some basic recommendations for preventing injury.
