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
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
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.
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.

Explain the unique bonding properties of carbon.
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.

The gluten-free diet was originally intended for people with celiac disease, but it’s now become a new fad diet for the general population. Many people state that gluten-free diets are beneficial for people who aren’t sensitive to gluten, while others suggest that there’s no benefit. Use credible resources to evaluate the argument yourself. Do you think there’s sufficient scientific evidence to support the use of a gluten-free diet in people who aren’t sensitive to gluten? Provide evidence that supports your argument.
Answer:
The gluten free diet is helpful for the people that are sensitive to food with gluten it which occurs due to the celiac disease. It was originally meant for the such people but it becomes a new fad. However, there is no compelling evidence to support that gluten free diet helps in health improvements n non sensitive people.
In other hand there are majority of doctors are against the use of gluten free diet is not good for various body organs like heart. A study concluded that there are lower risk of heart disease in people take more gluten. Doctors and various study suggests that people with no celiac disease should not avoid gluten.
Answer:
There’s no benefit to a gluten-free diet for people who aren’t sensitive to gluten. Many websites state benefits of a gluten-free diet. These benefits range from weight loss to improved heart health. None of these sites backed up their claims with scientific research. More credible sites consistently state that there’s no scientific research to back up these claims. Right now, there’s no evidence that supports the benefits of a gluten-free diet in people who aren’t sensitive to gluten.

Explanation:
Lipids are fatty tissue, or fats in the cells. Blubber is fat. The fat helps insulate animals from cold water, especially in the Arctic known for being freezing. Fats can help maintain and keep body heat, hence why skinnier people are colder. Without lipids, they would most likely freeze.

Respond to the following based on your reading.
Colonization is largely blamed for bringing smallpox to the Americas. Why was this disease so devastating to Native Americans? Why can we now travel to different parts of the world and avoid contracting analogous diseases?
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.
