Why is it difficult to male level 4 organs in a lab?

Answers

Answer 1

Answer:

By providing an example using one organ for each of the four levels of complexity, we have the following:First level organ: Skin; this is because it takes up a few cells. Second level organ: Windpipes; this is because they have more complex shapes with multiple cells. Third level organ: Stomach; this is because the stomach has to act on demand instead of a flow. Fourth level organ; Heart. The reason it is difficult to make level four organs in a lab is that it has a complicated architecture with several cells, blood vessels and tiny capillaries included. So far, scientists are yet to fully develop solutions for the level four organs and hence, difficult to create in a lab.

Why doesn't a gummy bear grow as much in sugar water as it does in normal water?

Answers

Salt molecules are much smaller than sugar molecules, so more of them will dissolve in water.

Hope this helps<3

Answer:

In comparison to the gelatin molecules in the candy, salt or sugar ions in water are significantly smaller. Water molecules go to a location with more solute to balance things out due to osmosis. The problem is that the water is trapped inside the candy and cannot escape. Because the Gummy Bear can't get any smaller, it keeps the same size.

Answers

Obliquity or tilt is the inclination angle of the Earth's axis. It is responsible for seasonal changes. The correct option is A) The tilt of the Earth is responsible for the seasons.

What is the Earth's obliquity -tilt-?

The term obliquity or tilt refers to the inclination of the axis of the Earth. The plane in which the Earth orbits around the sun is not orthogonal to the Earth’s axis of rotation. The axis has an inclination angle called ecliptic obliquity.

Obliquity is a determinant of seasons' existence. Thanks to this inclination in the axis of the Earth there are seasons. If tilt would equal cero, there would not be any season or temperature change in different regions of the Earth. So tilt becomes a significant factor, especially for high latitude areas.

Obliquity is one of the three Milankovitch cycles, together with precession and eccentricity. These are used to explain natural climatic changes through the history of the Earth.

The correct option is A). The tilt of the Earth is responsible for the seasons.

Will mark brainliest if the answer is correct: ""how does the presence of reptilian and mammalian nephrons provide evidence for the relatedness of birds and other vertebrates?""

Answers

Answer:

Nephrons in birds, mammals, and reptiles are all extremely similar, more so than other structures in the bodies of different species, solidifying the relatedness through similarity.

Explanation:

Birds can be said to have "mammal-like" nephrons from the number of loops and overall structure of their kidneys, which, although they look very different, serve the same purpose and do it in largely the same way. Reptiles also have mammal-like nephrons, and it can be assumed that this evolutionary trait was kept because the specific structure of the nephrons is generally the most efficient.

The presence of reptilian and mammalian nephrons provide evidence for the relatedness of birds and other vertebrates because the nephrons are similar to that of reptiles and mammals and other birds and vertebrates.

What are nephrons?

Nephrons are the functional unit of the kidney. There are many nephrons present in a kidney, it contains tubules and corpuscles.

The formation of urination is done by nephrons, the three functions of nephrons are filtration, reabsorption and secretion.

Thus, the presence of reptilian and mammalian nephrons provide evidence for the relatedness of birds and other vertebrates because the nephrons are similar to that of reptiles and mammals and other birds and vertebrates.
