Why do waves that travel through basalt have a higher velocity than a wave traveling through sand?
Answers
Answer:
Read Explanation
Explanation:
Even though the technology does not exist to travel into all of Earth’s layers, scientists can still learn a great deal about Earth’s structure through seismic waves. Seismic waves are vibrations in the earth that transmit energy and occur during seismic activity such as earthquakes, volcanic eruptions, and even man-made explosions. There are two types of seismic waves, primary waves and secondary waves. Primary waves, also known as P waves or pressure waves, are longitudinal compression waves similar to the motion of a slinky (SF Fig. 7.1 A). Secondary waves, or S waves, are slower than P waves. The motion of secondary waves is perpendicular to the direction of the wave travel, similar to the motion of vigorously shaking a rope

Vaccines have been subjected to quite a bit of controversy in recent years. Currently, the Centers for Disease Control and Prevention (CDC) recommend that healthy people receive a flu vaccine every year. What are your current perceptions of the flu vaccine? Do you think these recommendations are appropriate? Explain your reasoning.
Answers
Answer:
There are many reasons to get an influenza (flu) vaccine each year.
Flu vaccination can keep you from getting sick with flu.
Flu vaccination can reduce the risk of flu-associated hospitalization for children, working age adults, and older adults.
Flu vaccination is an important preventive tool for people with chronic health conditions.
Flu vaccination helps protect women during and after pregnancy.
Flu vaccine can be life-saving in children.
Flu vaccination has been shown in several studies to reduce severity of illness in people who get vaccinated but still get sick.
Getting vaccinated yourself may also protect people around you, including those who are more vulnerable to serious flu illness, like babies and young children, older people, and people with certain chronic health conditions.
Explanation:
Influenza is a potentially serious disease that can lead to hospitalization and sometimes even death. Every flu season is different, and influenza infection can affect people differently, but millions of people get flu every year, hundreds of thousands of people are hospitalized and thousands to tens of thousands of people die from flu-related causes every year. An annual seasonal flu vaccine is the best way to help protect against flu. Vaccination has been shown to have many benefits including reducing the risk of flu illnesses, hospitalizations and even the risk of flu-related death in children.
Flu vaccines helps to reduce the risk of flu-associated illness. And the recommendations made by CDC that healthy people receive a flu vaccine every year is appropriate.
What is flu?"Also called influenza is a viral infection which can be deadly in high risk groups."Flu symptoms include- fever, cough, cold, fatigue, headaches and muscle pain.It causes asthma, pneumonia and chronic diseases.What is flu vaccines?"These are the vaccines that protect against infection by influenza viruses."What is CDC?"It is the National public health agency of the United States."Hence, in order to reduce the disease caused by flu, it is recommended to receive a vaccine.

A lichen is an organism that structurally appears to be a single organism. But a lichen is actually two different organisms—a fungus and green
algae-living together as one organism. The fungal partner derives its nutrition from the photosynthesizing algae. How does a lichen differ in its
photosynthetic activity from Elysia chlorotica, the sea slug that's considered to be a photosynthesizing animal?
CA In lichens, the fungi photosynthesize on their own, while Elysia chlorotica forms a relationship with a photosynthesizing plant.
B. In lichens, the relationship with the algae lasts throughout the life cycle, but in Elysia chlorotica, the relationship occurs only
during the immature juvenile stage of the slugs life cycle.
OC Lichens can photosynthesize only because of the living algal partner, while Elysia chlorotica incorporates chloroplasts from
algae into its cells.
D. In lichens, the association between the fungi and algae is permanent, while Elysia chlorotica associates with a
photosynthesizing organism only when it requires food.
Answers
Answer:
The correct answer is option C. Lichens can photosynthesize only because of the living algal partner, while Elysia chlorotica incorporates chloroplasts from algae into its cells.
Explanation:
Elysia chlorotica is an animal of the mollusk member that is known as the animal that can make its own food in unfavorable conditions. Elysia chlorotica search out plants and they eat them. They assuredly don't photosynthesize n its own.
They take the mechanism that permits plants to collect sunlight based vitality. The slugs take up these smaller than normal machines, called chloroplasts, into their skin, which turns them emerald green. While Lichens can photosynthesize only due to the living partner algae that can photosynthesize for both.

How would the quantity of stomata compare between plants in tropical environments and plants in hot, arid climates? -Plants in tropical climates would have fewer stomata because they would need to prevent the absorption of too much water from the atmosphere. -Plants in hot, arid climates would have fewer stomata because they would need to prevent undesirable water loss from the plant leaves. -Plants in hot, arid climates would have more stomata because they would need to release heat from the leaves to prevent dehydration. -Plants in tropical climates would have more stomata because they would need to absorb more water from the air than plants in arid climates.
Answers
Answer:
-Plants in hot, arid climates would have fewer stomata because they would need to prevent undesirable water loss from the plant leaves.
Explanation:
I took the test and got this right.
The necessity to minimize unwelcome water loss from the plant leaves would cause plants in hot, arid areas to have fewer stomata. So, the correct option is B.
What is Stomata?The little apertures known as stomata are found just on epidermis of leaves. Stomata are visible under a light microscope. Stomata can be found on the stems and other portions of various plants. In exchange of gases and photosynthesis, stomata are crucial.
Because they need to take in more airborne water than plants in arid areas, tropical plants would have more stomata. Since they must prevent unwelcome moisture loss from plant leaves, plants in warm, arid climates would develop fewer stomata. The necessity to minimize unwelcome water loss from the plant leaves would cause plants in hot, arid areas to have fewer stomata.
Therefore, the correct option is B.
