what is the difference between plant cell nd animal cell​

Answers

Plant cells have walls and chloroplasts while animal cells do not

A plant cell contains a cell wall and chloroplasts, while animals cells do not have these cellular structures.

Chloroplasts are organelles required to produce energy in the form of ATP and thus synthesize simple carbohydrates (e.g., glucose) by the process of photosynthesis.

Cell walls are cellular structures that help to support and shape plant cells.

Moreover, plant cells generally contain big vacuoles, whereas animal cells generally exhibit small vacuoles.

In conclusion, a plant cell contains a cell wall and chloroplasts, while animals cells do not have these cellular structures.

Briefly explain how DNA profiling is used to identify individuals.

Answers

A sample of DNA is taken from blood of saliva. PCR makes lots of copies, or amplifies the DNA. We then add restriction enzymes to cut the DNA at palindrome sequences. We then run the DNA through gel Elecrophoresis. Each person has unique short tandem repeats that cause a unique number of cuts by the restriction enzyme. These cuts are separated by size on gel electrophoresis, so no two people have the exact same pattern. We can compare individuals banding patterns to what is found at a crime scene, taken in previous samples, in a baby, and the sample that matches all the banding patterns will be the individual.

Answers

Ava has been reading about the interactions among the components of the Earth. This group of components work together to make a system.

The group of components of the Earth work together to make an environment we live in.

What are the different components of the Earth?

The interactions between Earth's five systems—the geosphere, biosphere, cryosphere, hydrosphere, and atmosphere—create the environment we are accustomed to.

The Earth's interior and surface, which are both formed of rocks, make up the first system, the geosphere. The second system is made up of the little area of the planet that may sustain life; this area is known as the biosphere. The third system contains the hydrosphere, or regions of Earth that are completely covered with water. The fourth system is the atmosphere, a gaseous envelope that maintains the planet's temperature while also supplying carbon dioxide for photosynthesis and oxygen for breathing. The cryosphere, which is composed of enormous amounts of ice in the poles and elsewhere, is the fifth system. The maintenance of the Earth as we know it depends on the interaction of all five of these vast and intricate systems.
