The feature of stem cell which enable them to replace cell in tissues are that they can divide indefinitely to generate new cells and they can convert into the different types of cells that make up the body as they divide.
What is a stem cell ?A stem cell is a cell that has the unique capacity to grow into different types of cells in the body.
They may be utilised in the future to replace cells and tissues that have been damaged or destroyed owing to illness.
Stem cells are classified into three types which are Embryonic stem cells, Adult stem cells, Induced pluripotent stem cells.
Embryonic stem cells provide new cells to an embryo as it grows and develops into a newborn.
Adult stem cells generate new cells as an organism matures and replace damaged ones.
Induced stem cells are stem cells created in the laboratory by scientists.

As surface water in a lake cools from 4 °C to 0 °C, the water expands and becomes less dense. Why is this change in the water beneficial to the organisms living in the lake? As the water cools to freezing, spaces form between water molecules, providing microhabitats for small organisms. Frozen surface water insulates the water below it, maintaining a habitat where organisms can overwinter. Cooler water is less viscous than warmer water, making it easier for organisms to move through the water. Less dense water holds more dissolved compounds, keeping water from freezing so organisms survive winter.
Answer:
As the water cools to freezing, spaces form between water molecules, providing microhabitats for small organisms.
Explanation:
This change in the water is beneficial to the organisms living in the lake because the water which freezes formed spaces between water molecules, that providing microhabitats for small organisms. The cold temperature causes formation of ice crystals on the surface of water which work as an insulator whereas the lower part of the water remain warm and the organisms can survive in that environment.

A. we have to apply for a license before we can reproduce
B. have to find a partner
C. go through the cellular process of MITOSIS to produce sex cells.
Answer:
B. have to find a partner
Explanation:
When two badgers get together and fall in love, a sperm cell from the father which contains a copy of half of his DNA, only half, combines with the egg cell of the mother, which contains half a copy of her DNA. The result is a brand new cell with all the information to divide and grow up into a brand new badger. The new child matures to be similar to our parents, but also unique, because she developed some traits from her mother’s DNA, and some from her father. Her new combination of traits can be passed on to her children, and again.

What is microscope?
The instrument that is used to observe tiny particles as well as objects or cell of the body has been known as microscope. One lens in the microscope has been used to magnify the image at least once. The main function of the lens has to bend the light in the direction of the eye and forms the larger image of the object.
There are several types of microscope and these are electron microscope,scanning probe microscope, stereomicroscope, simple microscope, and light microscope.The main function of the lens has to bend the light in the direction of eye and forms the larger image of the object.
Each microscope have different function and ability to observe the object. As we know that the size of the cell has very small and it has impossible to observe it without microscope. So, microscope helps to observe the interior part of the cell and it will help in the study of different part of cell.
Therefore, The microscopes we use today are far more complex than those first microscopes like the one used in the 1600s by Anton van Leeuwenhoek.

Consider this plant cell. The organelles in a plant cell are labeled. Part G is the middle layer of the cell. Which organelle is labeled G?
Answer:
Hi. You didn't show the picture that shows organelle G, but since you showed that organelle is the middle layer of the cell, we can say that it is the plasma membrane.
Explanation:
In general, we can state that the plant cell has three layers, the cell wall, the plasma membrane and the cytoplasm. The cytoplasm is the inner layer, where most of the organelles and the cell nucleus are located. Above the cytoplasm is the plasma membrane, which is semi-permeable and promotes the regulation of the entry and exit of substances from within the cell. Above this membrane is the cell wall, which is an impermeable structure that protects the cell and promotes its rigidity. In this case, we can consider that the middle layer of the cell is the plasma membrane.
