Answers

Answer 1

Answer: The borders (coastlines) of the continents underwent a number of changes since the split. Often, chunks of land were washed away with water, slowly or in bigger portions. The coast was generally "smoothed" by the ocean currents too, and in some places more land was added with the material that the ocean currents brought.

Then, the tectonic plates continue to move, so this adds to the changes of the shape of the continents.

Imagine that you work at the medical examiner's office for a major metropolitan city. As Chief Medical officer, you investigate suspicious deaths and provide toxicology services for the county. Unfortunately, it's been a busy week. In the past five days, seven people have died, all with similar symptoms. It is your job to examine the data and determine the cause of death for these victims. The first was a 12-year-old girl. Her parents said that she was awake in the middle of the night complaining of a stuffy nose and sore throat. They gave her an extra strength Tylenol and sent her back to bed. At 7am the next morning, the parents discovered that the girl had collapsed on the bathroom floor. An ambulance rushed the girl to a nearby hospital, where she was pronounced dead. That same day, paramedics found the second victim unconscious on his kitchen floor after what they thought was an apparent heart attack. Sadly, the victim's brother and fiancée also collapsed later that night while the family gathered to morn his passing. Both had taken Tylenol to help them cope with their loss shortly before collapsing; neither survived.In the next four days, four other similar deaths were reported, all in the same neighborhood and all with similar symptoms. Are these seven deaths related? What is causing these people to die? It is your job to answer these questions before more deaths are reported.Symptoms exhibited by most patients: (i)-Dizziness(ii)-Confusion(iii)-Headache(iv)-Shortness of breath/rapid breathing(v)-Vomiting(vi)-Most deaths were very rapid, occurring within a few hours of symptoms.Explain whether or not you think these 7 deaths are related, and what questions you would ask the families of the victims.

trimming off infested plant branches
* never sterilizing tools
using chemicals only when necessary

Answers

Answer:

The correct answer is "never sterilizing tools".

Explanation:

Integrated pest management (IPM), also known as integrated pest control (IPC), is a series of recommended practices to reduce and control the development of pests in plants of interest. Never sterilizing tools is not part of following a IPM approach. Actually, it is recommended to sterilize tools to eliminate any risk of contamination and spreading the pests that could result from handling contaminated plants.

The right answer for the question that is being asked and shown above is that: "never sterilizing tools.' All of the following are important integrated pest management (IPM) strategies, except: never sterilizing tools. Tools should be sterilized before bringing into use.

Answers

Answer:

The block o time in the geological time scale are called:

Eon: The biggest ones

Eras: Which are the middle ones

Periods: Which are the smallest ones.

Explanation:

The geological time scale classifies the lapses of time in different gradients. It does it like that to optimize the retrieval of data and locate the objects and phenomenons of study to analyze them and conduct the research in an organized way. Eons are classified in Archean, Proterozoic, and Phanerozoic. Eras are classified in: Early archean, middle archean, late archean, Early proterozoic, Middle proterozoic, late proterozoic, Paleozoic, Mesozoic, Cenozoic. Periods are classified in Cambrian, Ordovician, Silurian, Devonian, Mississippian, Pennsylvanian, Permian, Triassic, Jurassic, Cretaceous, Tertiary, Quaternary.

The blocks in the geological time scale are: Eons , Era , and Periods

The rate and direction of reactions are greatly influenced by the _____.

Answers

Answer:

The law of mass action and molecular concentration

Explanation:

Law of mass action: According to this law, the rate of chemical reaction is directly proportional to the masses of the reacting substance, at a constant temperature.

Molecular concentration: It is no of moles of solute dissolved in a liter of solution. No of molecules of reactants increases when we increase the molecular concentration of the reactant, which in turn increases the frequency of collision and hence the rate of reaction and direction.

The rate and direction of reactions are greatly influenced by the Law of Mass action or molecular concentration because they relate to the same principle

A tiny rocky island in the South Pacific is home to a very small food chain. Coconut palms grow on the island and drop coconuts. The coconuts are eaten by coconut crabs. The coconut crabs are then eaten by seals. According to an ecological energy pyramid, the seals would receive about ___________ of the energy that the crabs receive.

Answers

Answer:

is 1%

Explanation:

Answer:

The seals would receive about 1% the amount of energy as the crabs.

Explanation:

The seals would receive about 1% the amount of energy as the crabs. The 10% rule says that as you move through an energy pyramid, the available energy decreases by about 90%, leaving 10% available energy for the next trophic level. Since the energy moved through two tropics levels, there is only about 1% available: 100% to 10% to 1%.
