1. Why would cells in some organs be consuming more oxygen than cells in other organs?
2. What happens to the glucose levels in the blood after a meal? Why does this happen?
3. Why might our muscles “burn” when we exercise for long periods of time?
Answer:
1- Im not sure, im so sorry! I hope i could help, if I have the answer ill edit this :)
2- When you eat some form of carbohydrate, the body breaks it down into glucose, such as pasta, fruit, bread or sugar. Glucose is absorbed into the bloodstream and, to be used for energy, insulin helps extract it from your blood into your cells.
3- The breakdown of molecules for energy occurs in the muscle region as people work out, which is why people may feel their muscles burning at the end of a difficult workout.
Explanation:
Intro:
Hello!!! Princess Sakura here ^^
Explanation:
1.) Every cell in your body needs oxygen for cellular respiration. Cellular respiration uses oxygen to break down sugar and create energy. The mitochondria are organelles that produce ATP and usually the muscle cells need the most because they are always working.
2.) The carbs you consume converts to blood sugar. So the more carbs you ingest the higher the levels of glucose you'll have released.
3.) It's because as we workout the breakout of molecules for energy happens in the muscle area, and that's because muscles have the most energy and needs the most energy.
How can humans mitigate society's and nature's harmful effects on Earth's Water?
Answer:
Use public transport, cycle or walk instead of using a car. Use facilities and trips run by local people whenever possible. Don't be tempted to touch wildlife and disturb habitats whether on land, at the coast or under water
Explanation:
how are large molecules formed from small molecules
Answer:
Most macromolecules are made from single subunits, or building blocks, called monomers. The monomers combine with each other using covalent bonds to form larger molecules known as polymers. In doing so, monomers release water molecules as byproducts.

The Grand Canyon is 446 km long, up to 29 km wide, and 1.6 km deep. The walls of the Grand Canyon are composed of nearly 40 different rock layers that represent about 1 billion years of Earth’s history. The rocks at the bottom of the canyon are metamorphic rocks formed 1.75 billion years ago. New sediments were deposited on top of those rocks, and mountain-building events around 755 million years ago tilted and lifted the new rocks. The total sandstone, shale, and limestone layers were deposited between 1,000 and 250 million years ago to form a rock sequence up to 1,525 m thick. WRITE YOUR ANSWER ON THE LINE.......IDENTIFY two geologic processes occurring in the Grand Canyon today that also contributed to the formation of the rocks that make up the Grand Canyon’s walls.
Answer:Geologists call the process of canyon formation downcutting. Downcutting occurs as a river carves out a canyon or valley, cutting down into the earth and eroding away rock.
Down cutting happens during flooding. When large amounts of water are moved through a river channel, large rocks and boulders are carried too. These rocks act like chisels, chipping off pieces of the riverbed as they bounce along.

Name and describe the two main parts of the skeleton.
Answer:The adult human skeleton usually consists of 206 named bones. These bones can be grouped in two divisions: axial skeleton and appendicular skeleton. The 80 bones of the axial skeleton form the vertical axis of the body.
Explanation:
Answer:
Besides bones, the skeletal system includes cartilage and ligaments. The skeleton is traditionally divided into two major parts: the AXIAL skeleton which includes the skull, spine, and ribcage,; and the appendicular skeleton, which includes the appendages and girdles that attach them to the axial skeleton.

In the lab, Ann cools a closed container containing 50 grams of steam until all of the steam becomes a liquid. She then cools the container until the liquid water freezes. Which remains constant during all of these changes?
Answer:
The mass
Explanation:
The only thing that will remain constant during the change of state is the mass of the water molecules.
Steam consists of water molecules in a gaseous state. The mass remains constant as it is cooled from steam to liquid water in a closed container and then frozen to become ice, still within a closed system.
The cooling system is just exchanging energy with the surrounding without exchanging any matter. Hence, the mass of the water molecules remains the same throughout the change of state.
How does potential energy transfer to kinetic energy?
Answer:
An object has potential energy (stored energy) when it is not in motion. Once a force has been applied or it begins to move the potential energy changes to kinetic energy (energy of motion). Hope this Helps :)
Explanation:
In dogs, curly tails are dominant over straight tails. If a pure curly-tailed dog is mated with a straight-tailed
dog, what percentage of their offspring will have curly tails?
Answer:
75%
Explanation:
If the two genes were equally dominant then the answer would be 50% because you have a 50/50 chance of getting a curly tailed dog. But since the curly tail gene is more dominant, the answer would have to be 75% because you are more likely to get a curly tailed dog.

Why is meiosis important for organism
Answer:
Meiosis is called as reduction division and it gives rise to four daughter cells which have only half of the genetic information that was present in the parent cell. Hence, it plays very important role in the formation of gametes (egg and sperm). The gametes are essential in the production of zygote which ultimately develops into a new organism.

It’s never a good idea to Water house plant with salty water plants would most likely die depending on how much of the solution is used how would salt water most likely affect plant cells
Answer:
Water would leave the large vacuole of the
cell and the plant will droop.
Explanation:
Water goes to high to low concentration and water wants to equalize. because there’s more water outside of the plant than inside of the plant so the water will leave meaning that the plant will droop.

Meteorologists want to design a system of instruments that will evaluate ocean air temperature and wind speed in order to predict catastrophic weather such as hurricane and cyclones what should they do before producing their first working system of instruments
Answer:
Build a prototype
Explanation:
A prototype may be defined as an early sample or a model or the release of the product that is built to test the concept or the process. It is generally made in use to evaluate some new design such as to enhance the precision by a system analysts and the users.
Thus in the context, a Meteorologists who wishes to design an instrument to evaluate the air temperature of the ocean and the speed of the wind so as to predict hurricanes and cyclones should first built a prototype of his concept and test the process before the production of the first working system.

why do cells need to be small?
Cells are small because they need to keep a surface area to volume ratio that allows for adequate intake of nutrients while being able to excrete the cells waste. That is why the cell needs to be small. The smaller it is, the larger the surface area to volume ratio is. ... This is why cells are so small
