Which Of The Following Is True For A Heating Curve?A.It Shows How The Pressure Of A Substance Changes

Answers

Answer 1

Answer:

B

Explanation:

A heating curve is a plot or graph wherein a substance is subjected to increasing temperature against time to measure the amount of energy it absorbs and changes state with increasing temperature. ... Nevertheless, a plateau is reached when the substance reaches melting point, i.e. changing from solid to liquid.

Summarize the 3 types of cell division: Binary fission, mitosis, and meiosis

Answers

Answer:

Binary Fission is the reproduction of prokaryotic cells (bacteria and bacteria-like Archaea) is accomplished through binary fission. Binary fission is essentially cloning. Barring mutations that may have occurred when the genetic material was copied (a process called replication), the two resulting daughter cells are identical to the parent cell.

Mitosis is a type of cell division that results in two daughter cells each having the same number and kind of chromosomes as the parent nucleus, typical of ordinary tissue growth.

Meiosis is a process where a single cell divides twice to produce four cells containing half the original amount of genetic information.

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.

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.

Answers

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.

1-2 Paragraphs About The Background Of Reaction Time Slowing Down Once You Get Older

Answers

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.

9) List these biomes in order from the greatest to least diversity (temperate
deciduous forest, tropical rain forest, temperate rain forest).

Answers

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.

Which of the following statements tells how facilitated diffusion differs from
simple diffusion?
A. Particles move through cell membranes without the use of energy by cells.
B. Particles tend to move from high concentration to lower concentration.
C. Particles move within channel proteins that pass through cell membranes.
D. Particles tend to move more slowly than they would be expected to move.

Answers

Answer:

I think its C but I am not sure, I hope this helps :)

Explanation:

The statement 'particles move within channel proteins that pass through cell membranes' indicates the reason for which facilitated diffusion differs from simple diffusion (Option C).

Diffusion (both facilitated diffusion and simple diffusion) refers to the movement of substances across biological membranes from an area of high concentration to an area of low concentration.

Facilitated diffusion and simple diffusion are two types of passive transport that do not require energy to move molecules/ions in favor of a concentration gradient.

In facilitated diffusion, specific membrane proteins known as carriers or channels help to the movement of substances in favor of a concentration gradient.

Conversely, in simple diffusion, small molecules (e.g. CO2 and oxygen) freely diffuse across a selectively permeable membrane in favor of a concentration gradient.

In conclusion, the statement 'particles move within channel proteins that pass through cell membranes' indicates the reason for which facilitated diffusion differs from simple diffusion (Option C).

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.
