(50 points)The picture is a cross section of a bone.
A cross sectional view of bone. X points to the inner layer. Y points to the middle layer.
Which structures of the bone are indicated by the arrows?
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.

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.

1-2 Paragraphs About The Background Of Reaction Time Slowing Down Once You Get Older
Answer:
Reaction times slow with age, and they correlate with scores on tests of higher cognitive functions many of which also deteriorate with age. The age-related changes in reaction times account for a substantial proportion of the age-related variance in higher cognitive functions (e.g., Deary, 2000. 2000Reflexes do slow with age. Physical changes in nerve fibers slow the speed of conduction. ... But the effect of age on reflexes and reaction time varies greatly from person to person. You can actually slow down—even reverse—the effects of aging by staying physically active.The next time some twenty-something complains that they feel old, you can reassure them that their feelings are, in fact, not ridiculous. After studying 3,305 people ages 16 to 44, researchers found that the brain's response time begins to decline at age 24.

Convergent plate boundaries can form which of the following?
Rift Valleys
Deep Ocean Trenches
Mountains
Volcanic Island Arcs
New Ocean Floor
Answer:
Deep Ocean Trenches, Volcanic Island Arcs and mountains
Explanation:
At a convergent plate boundary two plates collides with one another. Based on the type of plate, different features can form at such a margin.
In a continental - continental crust collision, both plates have the same density so, they build up on collision to form a mountain. In an oceanic - continental crust convergence; the oceanic plate is denser and it subducts. This leads to the formation of trenches. Also, here, the subducted plate will melt and a crack within the crust can allow for the melt to reach the surface and solidify to form volcanic Island arcs. Oceanic - oceanic crust convergence is also known.Pls help me , if I get this right I get a A

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.

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

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.

temperatures.
•Lithosphere:
•Asthenosphere:
•Mesosphere:
Answer:
lithosphere
Explanation:
is up of brittle crust and the top part of upper mantel and also the coolest and most rigid part of the earth
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.

What do codons in DNA code for?
Answer:
mRNA and then amino acids
Explanation:
Codons are triplets (3) bases that code for defined amino acid sequences.
DNA is transcribed into mRNA. The mRNA codons are then translated into amino acid chains that form proteins.
Each codon codes for an amino acid, which is brought to the growing polypeptide chain by tRNAs via complementary base pairing.
