The moro reflex is most likely to be produced when ________.
Compare the use of coal to the use of petroleum from 1800 to 2004.
Answer:
The use of coal increased during this time period as there was more and more industries and factories setup at time.
The use of coal increased and thus global warming. Burning of coal was the leading cause of global warming because it releases more and more carbon dioxide which is a major green house gas.
Petroleum use rose after 1950 due to mechanization. More number of vehicles were on road and that is the reason petroleum use rose up during that time.
Exocytosis is the process by which vesicles in the cytoplasm fuse with the cell membrane, releasing their contents into the cell's external environment. This is the form of transport used by a cell to dispose of large molecules. How does exocytosis help a cell maintain its homeostasis?
A. Cells must dispose of wastes in order to maintain their homeostasis.
B. In order to maintain their homeostasis, cells must release large molecules so that they can replicate themselves.
C. Cells must regularly lose part of their membranes in order to maintain their homeostasis.
D. In order to maintain their homeostasis, cells must release the exact same chemicals as they take in.
Answer:
A
Explanation:
took the test
Cells must dispose of wastes in order to maintain their homeostasis. So, the correct option is (A).
What is Homeostasis?Homeostasis is defined as a state of stable internal, physical, and chemical conditions maintained by living systems that are optimal functioning conditions for the organism and includes a number of variables such as body temperature and fluid balance, which have been described by some is kept within the prescribed limits.
It is the self-regulation process by which an organism maintains stability by adjusting itself to the best conditions for its survival.
Exocytosis is defined as the process by which vesicles in the cytoplasm fuse with the cell membrane, releasing their contents into the external environment of the cell as a form of transport used by the cell to dispose of large molecules to maintain the homeostasis.
Thus, cells must dispose of wastes in order to maintain their homeostasis. So, the correct option is (A).

A pregnant woman at 37 weeks gestation calls the clinic to say she thinks that she is in labor. the nurse instructs the woman to go to the health care facility based on the client's report of contractions that are:
A pregnant woman should go to the healthcare facility when she experiences regular contractions that increase in frequency and strength, do not abate with rest, and come at intervals of 30 to 70 seconds apart, especially if accompanied by back pain radiating to the abdomen, a bloody discharge, or when her water breaks.
The nurse instructs the woman to go to the health care facility based on the client's report of contractions when they have certain characteristics that indicate the onset of true labor. True labor contractions are regular contractions that become more frequent and powerful over time. They do not go away with rest or hydration, and they increase in strength as labor progresses. In particular, a pregnant woman might be in true labor and should seek immediate medical attention if she experiences:
Pain in the lower back, with the pain radiating towards the front abdomen and possibly down the legs.Contractions that are consistently increasing in strength, are close together, and come on a regular basis, typically 30 to 70 seconds apart.Bloody discharge due to the detachment of the mucous plug.The water breaks, which often leads to a significant increase in the strength of the contractions.Presence of these symptoms, especially closer to the full term of the pregnancy (around the 37th to 38th week), usually prompts healthcare providers to recommend that the woman go to the hospital or birthing center. Conversely, false labor signs include irregular and inconsistent contractions that may stop with rest or changing positions, and are generally less intense.

Smita wants to find new ways to recycle materials. Which field of study would be most useful to her?
A. Meteorology
B. Chemistry
C. Microbiology
D. Zoology
Answer:
Option B
Explanation:
The chemical properties of a material play a very important role in recycling and reusing any thing.
For instance - if a plastic on melting transforms into a form which cannot be re-converted into its original form, then such plastics are not reusable materials
A recyclable material must be able to regain its original molecular structure and size though physical processes such as heating, melting, remolding etc.
hence, option B is correct

A pharmaceutical company claimed that experiments showed that its drug could effectively reduce the growth of cancer cells by 35 percent. However, when five independent laboratories conducted the same experiment, they measured a reduction rate of only 5–8 percent.
How did these laboratories show that the pharmaceutical company’s claims were invalid?
The labs used the pharmaceutical company’s inadequate data.
The labs produced false data.
The labs recorded data incorrectly.
The labs were unable to reproduce the pharmaceutical company’s data.
These independent laboratories show that the pharmaceutical company’s claims were invalid through the fact that these labs were unable to reproduce the pharmaceutical company’s data. Thus, the correct option for this question is D.
What do you mean by Independent laboratories?Independent laboratories may be defined as a laboratory that typically performs all sorts of experiments on the basis of clinical pathology procedures. But these laboratories are not affiliated or associated with a Hospital or any governmental instituitions.
According to the context of this question, a pharmaceutical company claimed the experiment that significantly illustrates the reduction of cancer cells by 35%. But the five independent laboratories interpret the different results. This demonstrates that these labs were unable to reproduce the pharmaceutical company’s data.
Therefore, the correct option for this question is D.

How are RNA and DNA used to make proteins?
DNA forms the monomers that make up RNA, and RNA forms the monomers that make up proteins.
RNA forms the monomers that make up DNA, and DNA forms the monomers that make up proteins.
DNA has coded instructions for making proteins, and RNA translates the code.
RNA has coded instructions for making proteins, and DNA translates the code.
Answer:
The correct answer is DNA has coded instructions for making proteins, and RNA translates the code.
Explanation:
We can understand this answer with the help of concept of central dogma. Central dogma is the flow of information from DNA to mRNA (transcription) and then decoding the information present in mRNA in the formation of polypeptide chain or protein (translation). Functionally, DNA maintains the protein-encoding information, whereas RNA uses the information to enable the cell to synthesize the particular protein.
RNA and DNA are used to make proteins as DNA has coded instructions for making proteins, and RNA translates the code.
Explanation:RNA plays a crucial role in the process of protein synthesis. It is synthesized from DNA through a process called transcription. Once the RNA is formed, it carries the genetic code from the DNA to the ribosomes, where the actual protein synthesis occurs. This process is called translation, and it is carried out by a type of RNA called messenger RNA (mRNA).
Further, transcription is a fundamental process in molecular biology where genetic information encoded in DNA is converted into a complementary mRNA (messenger RNA) molecule. It occurs in the cell nucleus and is catalyzed by an enzyme called RNA polymerase. Therefore, DNA provides the instructions for making proteins, and RNA acts as an intermediary to carry out this process.

Electric charge drives this series of pumps and triggers known as ETS reactions. What is the net effect of these reactions?
A. ATP become ADP as hydrogen ions are pumped back and forth across the matrix.
B. ATP is created as oxygen is consumed, and water is produced along the way. C. Energized molecules, such as NAD and FAD, accept electrons as ATP is produced.
D. NADH and FADH2 form water molecules that pump ATP back and forth across the matrix.
The correct answer is:
B. ATP is created as oxygen is consumed, and water is produced along the way
Explanation:
Most eukaryotic cells have mitochondria, which generate ATP from products of the citric acid cycle, fatty acid oxidation, and amino acid oxidation. At the mitochondrial internal membrane, electrons from NADH and FADH2 pass within the electron transport chain to oxygen, which is degraded to water.
