Describe each type of volcano. Shield volcano: Cinder volcano: Composite volcano:
Answer:
Sheild Volcano-a broad domed volcano with gently sloping sides, characteristic of the eruption of fluid, basaltic lava.
Cinder Volcano-a broad domed volcano with gently sloping sides, characteristic of the eruption of fluid, basaltic lava.
Composite Volcano-a broad domed volcano with gently sloping sides, characteristic of the eruption of fluid, basaltic lava.
Explanation:
I had to learn these in 6th grade. Have a good day
A volcano is a crack in the crust of a planet, such as Earth, that enables molten lava, volcanic ash, and vapors to exit from a magma chamber beneath the surface.
Shield volcanoes: These are almost entirely composed of fluid lava flows. Flow after flow keeps pouring out in all orientations from a central summit vent, or group of vents, forming a broad, gently sloping cone with a profile similar to that of a warrior's shield. They are slowly built up by the accumulation of multitudes of highly fluid lava flows known as basalt lava, which spread widely over long distances and then cool as thin, gently dipping layers.
Cinder Volcano: The most basic type of volcano is a cinder cone. They are made of congealed lava particles and blobs ejected from a mono vent. When gas-charged lava is violently blown into the air, it splits into small fragments that consolidate and fall as cinders around the vent, forming a circular or oval cone. Often these cinder cones have a bowl-shaped crater only at the summit and rarely rise higher than a thousand feet above the surrounding terrain.
Composite Volcano: Some of the most majestic mountains on the planet are composite volcanoes, also known as stratovolcanoes. They are steep-sided, symmetrical cones with large dimensions made of varying thicknesses of a lava flow, volcanic gases, cinders, blocks, and bombs that can rise up to 8,000 feet above their bases.

A. X-compact; Y-spongy
B. X-spongy; Y-marrow
C. X-spongy; Y-compact
D. X-marrow; Y-spongy
Answer:
it is b X-spongy; Y-marrow, i am doing the test, and the other person is correct.
Explanation:
The arrows point to the bone formations called X-marrow and Y-spongy. So, the correct option is D.
What are Compact and spongy bones?Osteons or haversian systems are tightly packed together to form compact bone. The osteon is made up of concentric circles (lamellae) of matrix surrounding a central canal known as the osteonic (haversian) canal. The bone cells (osteocytes), which are situated between both the rings of matrix, are found in regions known as lacunae.
The bone marrow stores fat and produces blood cells. Spongy bone, also known as cancellous bone, is composed of tiny, needle-like bone fragments organized in a honeycomb pattern. Bones that are more flexible can still be strong while weighing less. In the given example, the arrows indicate to a X-marrow and Y-spongy bone structures.
Therefore, the correct option is D.

In your own words explain how the structure of the cell membrane determines what can and cannot pass through the cell membrane.
Answer:
The cell membrane is semi-permeable. (or selectively permeable). The unique structure of the cell membrane allows small substances (like oxygen or carbon dioxide) to easily pass through.
Explanation:
The principal components of the plasma membrane are lipids (phospholipids and cholesterol), proteins, and carbohydrate groups that are attached to some of the lipids and proteins. A phospholipid is a lipid made of glycerol, two fatty acid tails, and a phosphate-linked head group.
Answer:
Explanation:
Because the cell membrane is a selectively permeable membrane it decides what it will allow to pass through the membrane wall and what will not

Cells genetically unique is it mitosis or meisis
Answer:
Meiosis
Explanation:
While mitosis makes two identical cells with the same numbers of chromosomes, meiosis makes four unique daughter cells, from which every cell has half of the number of the chromosomes as the parent cell.
Meiosis is the specified form of cell division, making the reproductive cells, like sperm and egg cells, for example.
The illustrations are models of cells and cell organelles.
Which model shows a prokaryotic cell?
a. I
b. II
c. III
d. IV
Answer:
b. ll
Explanation:
I took the quiz and got it right.
Image II shows a model image of a prokaryotic cell.
What is a cell?
A cell is a basic unit of life. There are two kinds of cells prokaryotic cells and eukaryotic cells.
Cells organize to form a tissue. Image II is of a prokaryotic cell. It is flagella.
Many prokaryotes have locomotory structures called flagella (plural: flagellum). A majority of protozoa and some bacteria move around. As opposed to motile bacteria, which solely use flagella to move, protozoa use cilia, pseudopods, and flagella to move.
Therefore, Image II shows a model image of a prokaryotic cell.

Answer:
Lithosphere:
The lithosphere is the rigid outermost layer of the earth known as the mantle and the crust. And it is defined by its rigid mechanical properties.
Asthenosphere:
This layer is highly viscous and is very mechanically weak and is located below the Lithosphere it is also known as the ductile region of the upper mantle.
Mesosphere:
The mesosphere is the third layer of the atmosphere, directly above the stratosphere and directly below the thermosphere. In the mesosphere, temperature decreases as altitude increases.

In meiosis I, HOMO-LOGOUS CHROMOSOMES separate (Option D).
Meiosis is a type of reductional cell division by which a parent cell produces four daughter cells, which contain half of the genetic material.
Meiosis has two successive rounds of cell divisions: Meiosis I and Meiosis II.
In Meiosis I, homo-logous chromosomes line up at the equator of the parent cell (Metaphase I) and then segregate to different daughter cells (Anaphase I).
In conclusion, in meiosis I, HOMO-LOGOUS CHROMOSOMES separate (Option D).

About the Heart and Circulatory System
The circulatory system is composed of the heart and blood vessels, including arteries, veins, and capillaries. Our bodies actually have two circulatory systems: The pulmonary circulation is a short loop from the heart to the lungs and back again, and the systemic circulation (the system we usually think of as our circulatory system) sends blood from the heart to all the other parts of our bodies and back again.

What is the difference between glucose and ATP?
Glucose is a storable form of energy, while ATP is a usable form of energy.
ATP is a storable form of energy, while glucose is a usable form of energy.
ATP is only a usable form of energy, but glucose can be used and stored.
Glucose is only a storable form of energy, but ATP can be used and stored.
The main difference between glucose and ATP is that Glucose is a storable form of energy, while ATP is a usable form of energy.
Glucose is storable form of energy because it can't be used as energy until it can be broken down by mitochondria of the cell while on the other hand, ATP is the usable form of energy which we can get from the break down of glucose molecules. Our cells use ATP as a fuel to do various activities of the cell so we can conclude that in glucose, energy is present in stored form whereas ATP is used as energy in various activities.

9) List these biomes in order from the greatest to least diversity (temperate
deciduous forest, tropical rain forest, temperate rain forest).
Tropical rainforest, temperate deciduous forest, temperate rainforest
I'm not too sure if the temperate forest is more diverse than the rainforest, so sorry if I'm wrong. Tropical rainforests are the most diverse because of the humidity, which is water. The water helps the soil stay healthy, which makes more plants, which makes more animals and insects.
I hope this helps! Good luck!
The biomes in order from the greatest to least diversity will be tropical rainforest, temperate deciduous forest, and temperate rainforest.
Tropical rainforests refer to the rainforests that occur in areas that have no dry season.
The temperate deciduous forest refers to a biome that always changes. It has seasons such as winter, spring, summer, and fall.
Temperate rainforest refers to the broadleaf or coniferous forests that receive heavy rain. This condition supports ferns, shrubs, etc.
It should be noted that the biome with the greatest diversity is tropical rainforest while the least is the temperate rainforest.
