Radiolaria are unicellular organisms. They have mineral skeletons (tests) that are composed
of silica. The tests are formed through the absorption of silicon
compounds. This skeleton is covered with cytoplasm, which is withdrawn
if the organism is disturbed."

Hope this helps:)

Water has some unusual properties due to its hydrogen bonds. One property is cohesion, the tendency for water molecules to stick together. The cohesive forces between water molecules are responsible for the phenomenon known as surface tension.
I think this depends on you because it your choice for yourself but I'll just state some information or facts about this career.
- The field is a specialization in biomedical engineering that can take four to eight years to master.
- Genetic engineering has been applied in numerous fields including research, medicine, industrial biotechnology and agriculture. In research GMOs are used to study gene function and expression through loss of function, gain of function, tracking and expression experiments.
- Success rates are incredibly low; on average, less than 10% of embryos survive to birth and a smaller percentage of those born survive to adulthood.
- The field of genetics allows you to work in medical as well as scientific research.
- To become a genetic engineering research scientist, you need a doctoral degree in a biological science.
- Genetic engineers can earn anywhere from $44,320 to $139,440 a year.
Hope this helps and if you could mark me as brainliest. Thanks!
1. The correct answer is: 3. Formation of stalagmites and stalactites .
Groundwater can be defined as a flow of water under the ground. This water is usually slightly acid, because it is formed when rainwater absorbs CO2 as it falls. That carbonic acid water sinks into the ground and moves through pores.
Groundwater dissolves away solid rock, so it is natural erosion force. As it travels through cracks, it enlarges them and potentially forms cave.
Also, groundwater carries dissolved minerals in solution that might be deposited as stalagmites or stalactites.
2. As the river flows it makes contact with soil, breaks the rocks (weathering) and carries with it sediments: gravel, sand, silt and clay (erosion).
Then, when a river encounters water, it deposits such sediments onto a flat area and forms alluvium (deposition). These sediments form several layers - beds. The delta becomes a main channel that divides land masses into streams – distributaries that look like a maze.
Answer:
The neuron will fire an action potential.
Explanation:
A neuron is a cell in the brain that transmit signals to other nerve cells.
The depolarization of a neuron occurs when the neuron moves to a cell membrane with a more positive value which makes it more likely to fire an action potential.
