Describe the circumstances of a solar eclipse.
A solar eclipse happens when the Moon passes in front of the Sun and casts a shadow across Earth.
For a total eclipse to take place, the sun, moon and Earth must be in a direct line. The second type of solar eclipse is a partial solar eclipse. This happens when the sun, moon and Earth are not exactly lined up. The sun appears to have a dark shadow on only a small part of its surface.

b. silica
Explanation:
!!
Explanation:
A crust is the outermost layer of a planet. The crust of the Earth is composed of a great variety of igneous, metamorphic, and sedimentary rocks. The crust is underlain by the mantle. The upper part of the mantle is composed mostly of peridotite, a rock denser than rocks common in the overlying crust.

Which of the following phrases describe the function of the digestive system?
l. Smooth, muscular tube connects the mouth to the stomach
ll. Muscular action in the esophagus pushed food to the stomach
lll. Structures called the microvilli to increase the surface area of the intestines
lV. Nutrients are made available to the body's cells
A. l and ll
B. ll and lll
C. ll and lV
D. lll and lV
Answer:
B. ll and lll
Explanation:
The question above is asking for the "function" of the Digestive System. Function refers to how the digestive system actually works.
I is not related to the function of the digestive system. It only describes the "esophagus."
II is called the "Peristalsis." This is one of the functions of the digestive system. This allows the food to move down the GI tract.
III is part of the process called "Segmentation." This is one of the functions of the digestive system. The increase surface area of the microvilli expands 25 times and this allows greater absorption of food.
IV is not related to the function of the digestive system.

The process of forming ATP is? A) Digestion. B) Cellular Respiration. C) Metabolism. D) nutrition.
Answer:
[tex]\boxed {\boxed {\sf B. \ Cellular \ respiration}}[/tex]
Explanation:
First, let's analyze each process.
A. Digestion
This is the process of breaking down food.
B. Cellular respiration
This is the process of converting glucose and oxygen to carbon dioxide, water, and ATP.
C. Metabolism
This isn't really a process. It's the collection of all the chemical reactions in the body to keep the body functioning.
D. Nutrition
This term also isn't a process. Nutrition involves food, nutrients, and health.
We are looking for the process that forms ATP. Therefore, the best answer choice is B. Cellular respiration
The process of forming ATP is Cellular Respiration. Therefore option B is correct.
The process of forming ATP (Adenosine Triphosphate) is primarily through Cellular Respiration.
ATP is the main energy currency in cells, providing the energy needed for various cellular activities.
Cellular respiration is a series of metabolic reactions that occur in the mitochondria of cells, where organic molecules (such as glucose) are broken down and oxidized to release energy.
This energy is used to synthesize ATP from ADP (Adenosine Diphosphate) and inorganic phosphate (Pi).
Through cellular respiration, cells efficiently convert the energy stored in food molecules into a readily usable form of energy (ATP).
Which powers essential cellular processes, including muscle contraction, active transport, and synthesis of macromolecules.
Therefore option B Cellular Respiration is correct.

Which statement illustrates bias in scientific research?(1 point)
A. A microbiologist publishes data funded by the National Institutes of Health that does not support their original hypothesis.
B. A botanist publishes data about plant growth that does not support their original hypothesis and is replicable.
C. An ecologist publishes data funded by a construction company which supports their original hypothesis that an endangered animal's territory is not endangered.
D. A zoologist publishes incomplete data on sloths which supports their original hypothesis and notes that more research is required.
Answer:
D
Explanation:
The statement that illustrates bias in scientific research is an ecologist publishes data funded by a construction company that supports their original hypothesis that endangered animal's territory is not endangered (option C)
In scientific research, bias can occur when the results or processes are manipulated on purpose. This usually occurs if:
The researcher wants the hypothesis to match the resultsThe researcher or sponsor has an economic interestScientific research occurs in situation B because it is convenient for the construction company to show that endangered animal's territory is not endangered as this would allow the company to build in certain areas and therefore, they are likely to manipulate the results of this research.
According to this, option B shows scientific bias. On the other hand, other options do not show bias because in these the results do not seem to be manipulated.

How do Limiting factors affect biotic potential? Please hurry and help me
Biotic factors that a population needs include food availability. Abiotic factors may include space, water, and climate. The carrying capacity of an environment is reached when the number of births equal the number of deaths. A limiting factor determines the carrying capacity for a species.
What makes the structure of Carbon so unique? Why is Carbon considered the building block of all life? (3 sentence minimum answer)
Answer:
The carbon atom has unique properties that allow it to form covalent bonds to as many as four different atoms, making this versatile element ideal to serve as the basic structural component, or “backbone,” of the macromolecules.
All living things contain carbon in some form. Carbon is the primary component of macromolecules, including proteins, lipids, nucleic acids, and carbohydrates. Carbon's molecular structure allows it to bond in many different ways and with many different elements.

What are some characteristics that protists and fungi both have that make them eukaryotes?
Answer:
They have a nucleus and other membrane bound organelles.
Explanation:
hoped this helped :)
The characteristics that protists and fungi both have that make them eukaryotes is the possession of a membrane bound nucleus and other organelles.
EUKARYOTES:
Eukaryotic cells are cells that possess a membrane-bound nucleus to house their genetic material (DNA). Eukaryotes also possess other membrane bound organelles like mitochondria, golgi apparatus etc. This feature particularly differentiates them from prokaryotic cells. Eukaryotic organisms include plants, animals, fungi, some protists etc. Therefore, it can be said that the possession of a membrane bound nucleus and other organelles is the characteristics that makes fungi and protists be considered eukaryotes.Learn more: https://brainly.com/question/21196976?referrer=searchResults

Distinguish between:
Bat and Dove
Answer and Explanation:
Bats are mammals of the order Chiroptera. With their forelimbs adapted as wings, they are the only mammals capable of true and sustained flight. Bats are more manoeuvrable than birds, flying with their very long spread-out digits covered with a thin membrane or patagium.
Their wings skeleton have the shape of finger/hands like a human.
Doves are the only family in the order Columbiformes. These are stout-bodied birds with short necks, and short slender bills that in some species feature fleshy ceres. They primarily feed on seeds, fruits, and plants.
#teamtrees #WAP (Water And Plant)
Answer:
Doves have beaks and no teeth, whereas bats have jaw bones with sharp teeth. Although they both fly, Dove and bats feature different structures that allow them to take flight. Doves have rigid, feathered wings that they flap completely in order to fly.

have been heated by the sun?
A) cool and moist

C) warm and moist
D) cold and dry
I need this today please help
Answer:
I'm pretty sure its c
Explanation:
Warm and moist kind of air mass forms over tropical waters that have been heated by the sun. Hence option C is correct.
What are topical waters?Topical waters are defined as water between the Tropic of Cancer (23.5° North latitude) and the Tropic of Capricorn (23.5° South latitude). In the Köppen climatic classification, a tropical climate is one in which the average monthly temperature is over 18°C. There is no winter season and there is more annual rainfall than annual evaporation.
A good illustration of this kind of fish is the goldfish. On the other hand, "tropical" or "warm water" fish require a water temperature that is optimal for their comfort and health. Although different species of fish have varying needs, tropical fish generally demand water that is between 76 and 80 degrees Fahrenheit (25 and 27 degrees Celsius).
Thus, warm and moist kind of air mass forms over tropical waters that have been heated by the sun. Hence option C is correct.
