Which type: Land breeze or sea breeze would most likely form on a warm, cloudless, summer day? How do you know? Explain

THXSSS PLEASE HELP AND HURRY

Answers

Answer:

Explanation:

Sea breeze is a breeze that comes from the ocean to the land. The breeze is usually more when the temperature difference between land and ocean is high especially when it is summer and hot afternoon.

When the temperature is hot both land and water are been heat up, the land begin to release heat and warm air will rise over the land. Water do not get heat up easily hence the air is cooler leading to high pressure on the ocean air then blows from here to the land.

Answer:

Sea breeze.

This is because sea breeze occur on hot summer days which is due to unequal heating on the land surface and sea surface

Explanation:

Land and Sea breezes are as a result of different rate of heating on land or sea surfaces along coastal areas.

Sea breeze occur in a warm, cloudless summer days because of the unequal heating of the land and water surfaces.

During the day, the land surface heat more that the water surface. The air that is above the land become warm and it is warmer than that on the sea surface but the warm air is lighter than cool air. The warm air above the land surface rise, and the cool air on the sea surface rises and replaced the land warm air . This is sea breeze

Explain the unique bonding properties of carbon.

Answers

Atomic number of carbon = 6.Electronic configuration has 2 electrons in k shell and 4 electrons in L shell.In order to attain the noble gas configuration, carbon should either gain 4 electrons or lose 4 electrons or can share it's 4 electrons with some other element.Gain of 4 electrons to form octet , 8 electrons in C⁴‐ anion is difficult because then a nucleus with 6 protons will uave to hold extra four electrons. Loss of 4 electrons to attain duplet , 2 electrons like He atom in C⁴+ cation is difficult as it requires large amount of energy to remove four electrons. Carbon , hence overcomes this difficulty by sharing its four valance electrons with other atoms of carbon or with atoms of other elements. These electrons contributed by the atoms for mutual sharing in order to acquire the stable noble configuration is called covalency of that atom . Hence carbon shows tetracovalency.The simplest molecule formed by sharing electrons, cvalent bonds can represent by electron dot structure.

Carbon , hence overcomes this difficulty by sharing its four valance electrons with other atoms of carbon or with atoms of other elements.

What do you mean by valence electrons?

A valence electron is an electron in the outer shell associated with an atom, and that can participate in the formation of a chemical bond if the outer shell is not closed.

Valence electrons are the electrons in the outermost shell, or energy level, of an atom. For example, oxygen has six valence electrons, two in the 2s subshell and four in the 2p subshell.

For neutral atoms, the number of valence electrons is equal to the atom's main group number. The main group number for an element can be found from its column on the periodic table.

Explanation:

Felipe believes that whenever the Moon is in the position that is shown from above (top view) in Diagram A, the Moon always looks completely bright in the view from Earth, as shown in Diagram B. Is Felipe correct? If he is correct, explain why the Moon always looks bright from Earth in that position, and explain how he should show light on the Moon in Diagram A. If he is incorrect, explain how else the Moon can look when it is in that position.

Answers

Answer: Felipe is wrong.

Explanation:

In diagram A, we can see that the light comes from the left, it first impacts on the Earth, and then we have the Moon.

Now, you can model this situation with a flashlight (the Sun) a basketball (the Earth) and a tennis ball (the Moon)

When you point with the flashlight at the basketball, the basketball will look bright, but it will cast a shadow behind it. This shadow will cover the tennis ball, and almost no light will reach the tennis ball, so it will not look bright.

This phenomenon is called a lunar eclipse, and this happens when the Earth is in between the Sun and the Moon. When this happens, we see the moon a bit darker and more reddish.

Felipe is incorrect, as it will not be possible to see the moon if it is in the position shown in the diagram.

We can come to this answer because:

It is only possible to see the moon when it is reflecting sunlight.In this case, no other type of celestial body must be in front of the moon, blocking the sunlight.As we can see in the question above, sunlight is being emitted from left to right.Although the moon is in the right direction to reflect this light, the earth is in front of the moon.Therefore, sunlight will not shine on the moon, because the earth will block it and cast a shadow over the moon.

Therefore, it will not be possible to see the moon, as Felipe said.

The correct answer would be 1.33 dandelions per square meter of land.

Size of quadrat = 1.5 square meters

Average number of dandelions per quadrat = 2

Total study area = 4500 square meter

Population density = number of organisms per unit area

There were 2 dandelions per 1.5 square meters

How many would be per square meter?

= 2 x 1/1.5 = 1.3333 dandelion per square meters

To 2 decimal places = 1.33 per square meters

Answers

Answer:

Killing pathogens and then using them to provide the body with active immunity is called IMMUNIZATION . This is often done in young children.

When the immune system treats otherwise harmless substances, such as pollen, as if they were invaders, a/n ALLERGY can occur.

HIV is a virus that attacks WHITE BLOOD CELLS in the body, weakening the immune system.

Polio used to be fairly common and devastating. Thanks to widespread vaccination against polio, the disease is now considered ABSENT, no longer infecting nearly as many people as it once did.

Arthritis is an example of a/n AUTOIMMUNE DISORDER where part of a person’s body is identified as foreign and attacked by the person’s immune system.

Immunization helps involves the injection of dead pathogens into the bloodstream. This helps in the release of antibodies which helps in protecting the body against further attacks in the future.

Allergy happens as a result of the body system treating and attacking harmless substances.

This is because the ships which brought immigrants into the country had someone who had small pox on board which spread and many got infected and killed due to lack of vaccine and treatment.

Immunization helps people to travel without having to worry about diseases.

Answer:

vaccination

allergic reaction

t-cells

autoimmune disease

Europeans had been exposed to the virus that causes smallpox for many generations, allowing them to acquire immunity to the virus. Native Americans were not exposed to smallpox or similar viruses before, so they had no immunity to the virus. In modern times, before traveling abroad, a person often receives vaccinations or other medications to avoid contracting the diseases specific to that region of the world.

Have you ever experienced a time when you couldn't really describe something you saw in a way that others could understand? If so, you may understand why some experts think eyewitness testimony is unreliable as evidence in scientific inquiries and trials. New insights into human memory suggest human memories are really a mixture of many non-factual things. First, memory is vague. Imagine your room at home or a classroom you see every day. Most likely, you could describe the room very generally. You could name the color of the walls, the floors, the decorations. But the image you describe will never be as specific or detailed as if you were looking at the actual room. Memory tends to save a blurry image of what we have seen rather than specific details. So when a witness tries to identify someone, her brain may recall that the person was tall, but not be able to say how tall when faced with several tall people. There are lots of different kinds of "tall." Second, memory uses general knowledge to fill in gaps. Our brains reconstruct events and scenes when we remember something. To do this, our brains use other memories and other stories when there are gaps. For example, one day at a library you go to quite frequently, you witness an argument between a library patron and one of the librarians. Later, when telling a friend about the event, your brain may remember a familiar librarian behind the desk rather than the actual participant simply because it is recreating a familiar scene. In effect, your brain is combining memories to help you tell the story. Third, your memory changes over time. It also changes the more you retell the story. Documented cases have shown eyewitnesses adding detail to testimony that could not have been known at the time of the event. Research has also shown that the more a witness's account is told, the less accurate it is. You may have noticed this yourself. The next time you are retelling a story, notice what you add, or what your brain wants to add, to the account. You may also notice that you drop certain details from previous tellings of the story. With individual memories all jumbled up with each other, it is hard to believe we ever know anything to be true. Did you really break your mother's favorite vase when you were three? Was that really your father throwing rocks into the river with you when you were seven? The human brain may be quite remarkable indeed. When it comes to memory, however, we may want to start carrying video cameras if we want to record the true picture. Which line from the text best explains the main reason memories change? Most likely, you could describe the room very generally. The more a witness's account is told, the less accurate it is The next time you are retelling a story, notice what you add You may also notice that you drop certain details Which word from the text best describes memories from our childhood?
