Answer:

peaks and valleys show population increase and decrease between 2 species or more.

Explanation:

the peaks and valleys are used to show predation hence if there is an increase in prey there will be an increase in the predators and if there is a decrease in prey there will be a decrease in predators therefore creating peaks and valleys in that graph hence demonstrating population interactions between the two species.

Frequency is referred to as pitch that is the number of times per second that a sound pressure wave repeats itself.

The units of frequency are known as hertz (Hz). Humans can hearing can hear sounds between 20 Hz and 20,000 Hz.

Answer:

cellulose

Explanation:

lipids are fats oils or waxes. cellulose is a fiber

Answer:

cellulose    

Explanation:

Examples of lipids include fats, oils, waxes, certain vitamins (such as A, D, E and K), hormones and most of the cell membrane that is not made up of protein. Therefore waxes are not the answer.

Steroids are lipids because they are hydrophobic and insoluble in water, but they do not resemble lipids since they have a structure composed of four fused rings. Cholesterol is the most common steroid and is the precursor to vitamin D, testosterone, estrogen, progesterone, aldosterone, cortisol, and bile salts. Therefore steroid and cholesterol is not the answer.

The ferric ions' cytochrome oxidase in the mitochondria makes a reversible chemical bond with cyanide. By preventing the conversion of oxygen to water, this essentially stops cellular respiration.

Heme-containing proteins include Fe3+, which cyanide binds to. As a result, the electron transport chain's terminal cytochrome complex IV is inhibited.

Cyanide's blockade of complex IV depletes ATP, which leads to cell death.

Because the molecules are so small and can disperse quickly throughout the entire body, cyanide can kill so quickly by damaging all major organs and tissues in a short period of time.

Therefore, electron transport system is affected by cyanide in cellular respiration.

Answer:

If the freshly created metamorphic rock is exposed to enough heat, it may melt and become molten (magma). Igneous rock is formed when molten rock cools. Sedimentary and igneous rocks can both create metamorphic rocks.

The process that would change metamorphic rock to igneous rock is to treat metamorphic rock at extremely high temperatures and pressure that effectively transform it into a molten state. And this molten magma cools and crystallizes completely giving rise to the production of igneous rock.

Metamorphic rock may be defined as a type of rock that is significantly obtained due to the series of alterations in the pre-existing rocks. These alterations emerge due to changes in environmental conditions.

According to the context of this question, igneous forms are synthesized when the molten metamorphic rock cools and crystallizes due to the result of volcanic eruptions and melted rock inside the earth's crust. This happens due to the generation of extremely high temperatures and pressure.

Therefore, the process of formation of igneous rock from metamorphic rock is well described above.

Answer:

endoneurium

Explanation:

The endoneurium is a layer of connective tissue composed of endoneurial cells that surround and protect the myelin sheath of each myelinated nerve fiber.

nerve fibers are insulated from one another by endoneurium.

A nerve fiber is a long axon from a nerve cell (neuron muscle). The body of the nerve cell is anatomically located either inside the ganglia of the peripheral nervous system or within the central nervous system.

The ganglionic neurons' axons that travel from the retina's vitreal surface to the optic disc make up the nerve fiber layer. These axons are not myelinated until they reach the optic disc and break through the sclera. The optic disc's white color is a result of oligodendrocytes' myelination of them at this point. They help in the communication of two nerve fibers.

Thus, nerve fibers are insulated from one another by endoneurium.

Because one original strand of the double-stranded helix is ​​found in each daughter molecule, the replication process is called semiconservative.

Replication is the process by which a DNA molecule generates two identical to itself, and is key in cell reproduction.

All cells in the body must have the exact same genome (as in asexual reproductive organisms, which are practically clones of each other) and this is achieved through replication.

The process consists of separating the two strands of DNA, each of which will function as a template to synthesize a new one.

That is, each of the two strands of DNA serves as a template to synthesize a new complementary strand of the template.

In the end, two DNA molecules are formed, each of the two DNA molecules has a new chain and one original strand, this mode of replication is called semi-conservative.

Therefore, we can conclude that because one original strand of the double-stranded helix is ​​found in each daughter molecule, the replication process is called semiconservative.
