Answer:
Because double bonds cause the hydrocarbon chain to bend. Therefore, the fatty acids cannot compact tightly together, reducing the van der Waals interaction between the fatty acids. The melting point of fatty acids is also affected by chain length. The longer the hydrocarbon chain is, the higher the melting point.
Explanation:
The theory of natural selection was first expounded by Charles Darwin and today it is believed to be the main process that brings about evolution.
This process is defined as the process whereby organisms who better adapt to their environment tend to survive and produce more offspring.
Hence, according to this statement, option C is correct.
More organisms are born than can survive.
Answer:
Data is used to evaluate the treatment that is provided to the patient in each episode of nursing diagnosis.
Explanation:
An outcome measure is a tool that is used to assess the current status of the patient that is influenced by the nursing interventions. It is marked by the status of the resolution for individual nursing diagnosis as being either resolved or not.
The data collected by outcome measures supports in establishing the foundation for providing the correct medical treatment to the patient. Which later helps to assess the treatment provided to the patient. It provides reliable and credible justification for the treatment on an individual patient level.
Below are a few examples of these outcome measures;
- Mortality
- Timeliness of care
- Safety of care
- Patient Experience
- Effectiveness of care

Question: What is the expected percent change in the DNA content of a typical eukaryotic cell as it progresses through the cell cycle from the start of the G1 phase to the end of the G2 phase
a. -100%
b. -50%
c. +50%
d. +100%
Answer:
d. +100%
Explanation:
S phase comes between G1 and G2 phases of the interphase of a cell cycle. S phase of interphase includes replication of DNA. The process of DNA replication doubles the amount of DNA present in the cell. The newly synthesized DNA is accommodated in the sister chromatids of chromosomes. Therefore, a cell with 2C DNA in the G1 phase would have 4C DNA at the end of the G2 phase. So, there is a +100% increase in the DNA content of a cell as it proceeds from G1 to the end of the G2 phase.
