A glacier advanced 12 feet during a 16-day period in January. The same glacier advanced 18 feet during a 24-day period in February.
Are the ratios of feet to days proportional for these two periods of time?
Drag and drop to correctly complete the statement.
Answer:
3 feet : 4 days
Explanation:
Ratio of feet to days in January: Ratio of feet to days in February:
12 feet to 16 days 18 feet to 24 days
Now let us reduce both to the lowest terms and compare;
Divide by 4 Divide by 6
3 feet : 4 days 3 feet : 4 days
For both time periods, the ratio of feet to days are the same.
Answer:
proportional

1. how many chambers does the human heart have?
2. what close the valves in the heart and why should they do this?
3. what do we call a pulse?
4. describe blood capillaries
Your heart has four separate chambers that pump blood, two on the right side and two on the left.
2. When the ventricle relaxes, the aortic valve closes to prevent blood from flowing back into the ventricle. When the aortic valve is not working properly, it can interfere with blood flow and cause the heart to strain to send blood to the rest of the body.
3. In medicine, a person's pulse is a pressure wave caused by the expansion of the arteries as a result of the circulation of blood pumped by the heart.
4. Capillaries are tiny vessels that branch out from arterioles to form networks around body cells.
Capillaries are very tiny blood vessels — so small that a single red blood cell can barely fit through them.

Plants vs animal Behavior Examples
Answer:
Behavior is the way that all organisms or living things respond to stimuli in their environment. Stimuli include chemicals, heat, light, touch, and gravity. For example, plants respond with growth behavior when light strikes their leaves.
Examples of this kind include the nest-building behavior of birds and the dam-building behavior of beavers. Imprinting. An example of animal behavior that combines instinct and learning is imprinting, often seen in birds such as geese and ducks.

how does bones make blood? Explain in detail
Answer:
red blood cells are formed in the red bone marrow of bones.
Explanation:
stem cells in the red blood bone called hemocytoblasts ( a stem cell for blood-cellular elements specifically )give rise to all the formed elements in blood.. If a hemocytoblast commits to becoming a cell called a proerythroblast, (A Proerythroblast is the earliest of four stages in development of the normoblast.)it will develop into a new red blood cell.

What change in volume is expected to result in a faster rate of diffusion ?
Answer:
When the cell increases in size, the volume increases faster than the surface area, because volume is cubed where surface area is squared. When there is more volume and less surface area, diffusion takes longer and is less effective

The karyotype, or chromosomal profile, for humans is shown. A karyotype can be used to investigate genetic disorders. The chemical colchicine is used in the production of karyotypes. Colchicine prevents spindle fibers from forming during the cell cycle what is a result if preventing spindle fibers from forming
Answer:
The correct answer is - Mitotic division stops in metaphase and cannot proceed to anaphase.
Explanation:
Spindle fibers do not form during metaphase of cellular division the chromosome would not move in opposite pole and the cell will not move to anaphase.
The chemical colchicine stops the assembling of the microtubules during metaphase of the cell division which prevents the formation of the spindle fibers and the cell did not move to the anaphase from metaphase in mitotic division.

D. Heterogeneous mixtures
Answer:
A Trailmix is a...
heterogeneous mixture
Explanation:
A heterogeneous mixture contains particles that are not the same, can be separated by physical means, and are not distributed the same throughout the mixture. Trail mix fits this description perfectly.
Trail mix is a heterogeneous mixture, which is in option D, as trail mix is a popular snack that typically consists of a combination of various ingredients, such as dried fruits, nuts, seeds, and sometimes chocolates or candies.
Trail mix is a type of snack that typically consists of a combination of ingredients like dried fruits, nuts, seeds, and sometimes chocolates or candies. These ingredients are intentionally mixed together to provide a variety of flavors, textures, and nutritional elements. Unlike homogeneous mixtures, where the components are uniformly distributed and appear the same throughout, heterogeneous mixtures have visible differences and variations within the mixture. In the case of trail mix, you can see the separation between the various ingredients, and they can be easily distinguished from one another.

Movement caused by warmer fluids rising and cooler fluids sinking is called ______________.
Answer:
Explanation:
convection current
The movement caused by warmer fluids rising and cooler fluids sinking is called convection currents.
What is convection current?The convection currents are the outcome of differential heating. The less dense, that is, lighter warm substances rise, while the denser, that is, heavier cool substance sinks. It is this movement that generates patterns of circulation called convection currents, in water, in the atmosphere, and in the mantle of the Earth.
Thus, convection currents are the answer.
