What method do scientists use to trace plant and animal extinctions through Earth's history

Answers

Answer 1

Answer:

Paleontology is the study of the history of life on Earth as based on fossils. Fossils are the remains of plants, animals, fungi, bacteria, and single-celled living things that have been replaced by rock material or impressions of organisms preserved in rock.

Explanation:

Answer 2
Because there are very few ways of directly estimating extinction rates, scientists and conservationists have used an indirect method called a “species-area relationship.” This method starts with the number of species found in a given area and then estimates how the number of species grows as the area expands.

How do living organisms maintain homeostasis within their bodies?

Answers

Answer:

The body regulates those levels in an example of homeostasis. When levels decrease, the parathyroid releases hormones. If calcium levels become too high, the thyroid helps out by fixing calcium in the bones and lowering blood calcium levels. The nervous system helps keep homeostasis in breathing patterns.

What is the difference between flu viruses and the measles virus?

Answers

Answer:Influenza and measles are viruses that both cause respiratory symptoms. The typical measles rash does not appear for 2-4 days, so during influenza season, symptoms of early measles can be confused with influenza.

Explanation:

Explanation:

Vaccines for both measles and flu already exist, however the flu vaccine must be updated because of the virus's ability to change and adapt in order to invade cells in the human body. The goal of researchers was to find genes in each virus that cannot survive changes.

By comparing two similar viruses which attack the body in similar ways through the lungs, researchers confirmed that the measles virus is much less open to evolutionary change by using an experimental technique called insertional mutagenesis to change the genes of each virus.

Which of the following answers is NOT correct with regard to convection currents?

A. Convection currents in magma drive plate tectonics.

B.Convection currents in magma are a result of density differences.

C. Convection currents play a role in the movement of Earth’s inner core.

D. Convection currents in magma are caused by temperature differences.

Answers

Answer: C....Convection currents play a role in the movement of Earth’s inner core

The statement which is not correct with regard to convection currents is as follows:

Convection currents play a role in the movement of Earth’s inner core.

Thus, the correct option for this question is C.

What is Convection current?

Convection current may be defined as a procedure that significantly involves the movement of energy from one place to another. It is basically the existence of current in a fluid through convection.

The inner core of the earth has appeared as solid as compared to other parts like the crust and mantle. Most liquid particles are definitely found on the mantle of the earth's surface.

Due to the presence of excessive liquid particles and compounds, the convection current is significantly noticed there.

Apart from this, magma is also a fluid that derives current through convection. It produces in a number of ways like magma driving plate tectonics, density differences in the magma, and temperature differences.

Convection currents are basically the movement of fluid with respect to temperature or density difference within the material.

Therefore, the correct option for this question is C.

Find 2 ways that natural gas forms. List the steps of the two carbon pathways below. Label each location with A for atmosphere, B for the biosphere, G for geosphere, or H for hydrosphere. Use P for the anthroposphere.

Answers

Answer:

Biogenic and thermogenic

Explanation:

Biogenic and thermogenic are the two ways or mechanism that is responsible for formation of natural gas. Biogenic gas is formed with the help of methanogenic organisms that is present in marshes, bogs, landfills, and shallow sediments. Thermogenic gas is formed from organic matter that is buried in the deeper earth where the temperature and pressure are very high.

The organic pathway of the carbon cycle is the pathway in which carbon moves from atmosphere, through producers, herbivores and other organisms in the ecosystems, and converted back to the atmosphere.

In geological pathway, carbon moves from the atmosphere, through the ocean to rocks and the mantle, and then back to the atmosphere.

The fruit's exterior surface is made up of the exocarp, the fruit's top layer. The tissue between the exocarp and endocarp is called the mesocarp. The innermost layer, called the endocarp, is situated just outside the seed coat.

Help!Just the name itself will make you giggle. It's a great word that conjures visions of slime and unpleasantness. It is perhaps the most annoying part of having a cold or allergies. Mucus, however, plays a very important role in defense of our bodies and our health. In fact, it's high time mucus got a lot more respect.First, there are some amazing facts about mucus that are worthy of respect. Humans produce about a liter of mucus every day, whether they are sick or not. Bony fish and some invertebrates (snails or slugs) also have mucus cells on the outside of their body. This external mucus creates a protective coating that prevents predators' toxins from doing harm. Humans produce mucus to protect our stomachs, our lungs, and several other systems.We tend to not like mucus because it is a considered a symptom or sign that something is wrong. We usually only see it when we are sick, and so we tend to dislike it. According to Michael M. Johns, III, MD, however, "mucus is incredibly important for our bodies." Johns, an assistant professor at Emory University, calls mucus "the oil in the engine" of our bodies. Without mucus, our engines, or bodies, would freeze up and stop working properly.Furthermore, mucus is not just the nasty gunk you see when you are sick. It lines the tissues in your mouth, your nose, throat, and lungs. It also is crucial in protecting your digestive system. Mucus puts a protective coating over the surfaces of these tissues, keeping them moist. Most of the time we don't notice mucus is making our lives better. It does its job quietly, making everything run smoothly, keeping our inner tissues soft and flexible enough to fight off invaders.Occasionally, though our mucus-making membranes go into overdrive. If you eat a hot pepper, your mucus membranes in your mouth and throat start producing extra mucus to protect you. If you come into contact with pollen, you may get a runny nose and start sneezing and coughing. When these things happen, your mucus systems start making more fluids to wash away the irritating particles. Mucus also has some antibodies that increase our ability to fight off bacteria and viruses.It's hard to appreciate what is essentially slime, but we have mucus for some very good reasons. It helps to keep us healthy and lets us know when our bodies are under attack. We would be wise to respect what our bodies do to keep us safe. So the next time you find yourself reaching for a tissue, remember mucus is your friend and ally.What's in a Name?Mucus is a great word, not only because it gives name to an important bodily function, but also because it is one of those words that simultaneously makes you feel grossed-out and giggly. Other words for this powerfully important human-health tool include slime and phlegm. Slang words for mucus include boogers and snot. All of these words have the same giggle-power, simply from the combination of consonants and vowels. By the way, mucus is an old word; it's been around since the mid-1600s and has roots back to Latin (mucere, to be moldy or musty) and Greek (myxa, mucus). While you may assume that words like snot and boogers are relatively new slang terms, they are not. Snot dates to 1560 and comes from an Old English word, gesnot, and has the same root as the word snout. The word booger is not quite as old but has been in use since the 1890s.Which states how "Making the Most of Mucus" convinces readers mucus is valuable? a. It discusses people's reactions to mucus and the word itself.b. It explains how mucus is really helpful.c. It lists the various creatures that carry and use mucus for health.d. It uses an example of eating a hot pepper to explain how mucus develops.
