Explanation:
Genetic variation in offspring during sexual reproduction is caused by
- crossing over
- independent assortment
- randomized fertilization
Further Explanation:
All the genetic information within the eukaryotic cell is stored within the nucleus as helical DNA. This DNA is tightly wound around histones as chromosomes. To produce daughter cells during cell division, the chromosomes (total number of chromosomes (2n)) are copied before the cell splits into two daughter cells. This process is known as mitosis, and occurs in cell division and growth processes. Two new nuclei are formed, along with identical cells. These are the same as the parent cell and the chromosome number (2n) is maintained.
Conversely in meiosis, the number of chromosomes (2n) is halved through meiotic divisions, producing 4 (n) germ cells (sperm or eggs), each containing half the number of chromosomes as its parent cell.
- crossing over: the exchange of segments of chromosome, between non-sister homologous or similar chromatids crossing over happens at chiasmata, the point where non-sister chromosomes are joined.
- independent assortment in metaphase I of meiosis: chromosomes align independently and genes segregate independently into new combinations ...in humans 2n, n = 23, 8 million combinations of chromosomes possible
- randomized fertilization: sperm cells fertilize an ovum to form a zygote. This occurs randomly by chance, to result in a complete set of chromosomes 2n, that is a novel combination of half each parent's number of chromosomes

The word in the blank should be 'segregation' :)
Answer: Carolus Linnaeus
Explanation:
Carlos Linnaeus created the binomial nomenclature system which gives scientific names to animals. Their genus and species is what classifies organisms.
Linnaeus also created the taxonomic system, which classifies organisms within different groups and subsets.

Answer:
This tool is divided into three sections representing the principles in the Medication practice standard: authority, competence, and safety.
Explanation:
Rights of Medication Administration
1. Right patient
- Check the name of the order and the patient.
- Use 2 identifiers.
- Ask patient to identify himself/herself.
2. Right medication
- Check the medication label.
- Check the order.
3. Right dose
- Check the order.
- Confirm the appropriateness of the dose using a current drug reference.
4. Right route
- Again, check the order and appropriateness of the route ordered.
- Confirm that the patient can take or receive the medication by the ordered route.
5. Right time
- Check the frequency of the ordered medication.
- Double-check that you are giving the ordered dose at the correct time.
- Confirm when the last dose was given.
6. Right documentation
- Document administration AFTER giving the ordered medication.
- Chart the time, route, and any other specific information as necessary.
7. Right reason
- Confirm the rationale for the ordered medication. What is the patient’s history? Why is he/she taking this medication?
8. Right response
- Make sure that the drug led to the desired effect. If an antihypertensive was given, has his/her blood pressure improved?
- Does the patient verbalize improvement in depression while on an antidepressant?
