Answer:4 to 8 weeks

Explanation:

Balloon size increases as the sugar increases in the solution.

As the yeast feeds on the sugar or sugar solution which produces carbon dioxide gas. Due to presence of balloon, there is no place to go so gas slowly fills the balloon. Carbon dioxide gas produces from yeast fills thousands of balloon.

That solution which have high amount of sugar in it will leads to higher concentration of carbondioxide gas in the balloon so we can conclude that balloon size increases as the sugar solution increases.

Answer:

What tells a muscle when to contract?​

Explanation:

(1) A message travels from the nervous system to the muscular system, triggering chemical reactions.

(2) The chemical reactions lead to the muscle fibers reorganizing themselves in a way that shortens the muscle--that’s the contraction.

(3) When the nervous system signal is no longer present, the chemical process reverses, and the muscle fibers rearrange again and the muscle relaxes.

Answer:

The nervous system generates a signal, which triggers a muscle to contract

Within the scientific community, peer review has become an essential component of the academic writing process. It helps ensure that papers published in scientific journals answer meaningful research questions and draw accurate conclusions based on professionally executed experimentation.

Explanation:

Answer:

Living things move, respond to stimuli, reproduce and grow, respire, and are dependent on their environment. Most living things need food, water, light, temperatures within defined limits, and oxygen. ... Some non-living things, such as rocks and water, were never living.

Answer:

contact inhibition.

Explanation:

This is how healthy cells know when to stop dividing. and a process called contact inhibition is when normal, healthy cells are touching other cells on all sides, they have a red light in the cell cycle and do not divide

I Hope This Helps!!!!

Answer:

cell cycle

Explanation:

The process then repeats in what is called the cell cycle. Cells regulate their division by communicating with each other using chemical signals from special proteins called cyclins. These signals act like switches to tell cells when to start dividing and later when to stop dividing. I don't understand what you are saying, but hope this helps!

Explanation:

Answer:

The carbon cycle, as the nitrogen cycle, occurs in all the spheres: Biosphere, Atmosphere, Geosphere and Hydrosphere.

Explanation:

Most Earth events involve interaction between multiple spheres. For example, rain is the movement of water (the hydrosphere) from the atmosphere to the lithosphere where it collects in lakes, rivers, or streams. Water is an important resource for inhabitants of the biosphere.

The Atmosphere-contains all the air in Earth's system. The upper portion of the atmosphere protects the organisms of the biosphere from the sun's ultraviolet radiation. It also absorbs and emits heat. This sphere is also where weather occurs.

The nitrogen cycle occurs in all the spheres and ecosystems. It passes through rocks, water, atmosphere, plants, etc.

In atmosphere and biosphere: Nitrogen is about 78% of the gases in the atmosphere an it’s a essential component of the living organisms. It enters plants through the microorganisms that convert this nitrogen into ammonia. After this conversion, the plants absorb this substance. It can pass to animals when they eat these plants. Then, when they urinate, bacteria convert ammonia to nitrogen again and it returns to the atmosphere.

Answer:

When looking at a plant cell and an animal cell, you will notice one significant difference (though there are many more). A plant cell has one large central vacuole, whereas an animal cell has many.

Explanation:

Have a great day, and spread some positivity!

A plant cell can be identified by the presence of a cell wall, a large central vacuole, and chloroplasts.

The cell wall is a rigid structure that surrounds the cell membrane. It is made up of cellulose, a type of carbohydrate. The cell wall provides support and protection for the cell. Animal cells do not have a cell wall.

The central vacuole is a large space filled with water. It is located in the center of the cell. The central vacuole helps to maintain the cell's shape and turgor pressure. Animal cells do not have a central vacuole.

Chloroplasts are organelles that contain chlorophyll. Chlorophyll is the green pigment that allows plants to photosynthesize. Photosynthesis is the process by which plants use sunlight to convert carbon dioxide and water into oxygen and glucose. Animal cells do not have chloroplasts.

If you examined a potato cell under a microscope, you would be able to see these features. The cell wall would appear as a thin, clear layer around the cell. The central vacuole would appear as a large, empty space in the center of the cell. The chloroplasts would appear as green, oval-shaped organelles.
