Repeated filtration as in activity one and activity two can be use to make contaminated water less contaminated and clean.

Contaminated water refers to water that contains impurities which make water unsafe and unfit for use.

Some examples of contaminated water is water puddle, in gutters and in swamps.

Contaminated water is a source of toxins and infections.

Contaminated water is purified by filtration.

The activity is designed to purify swamp water.

In activity one, the water is collected in bowl.

A funnel an an old T-shirt is used to filter the water to remove dirt and particles.

After activity one, the water looks neater and has little small.

To further purify the water, activity two is carried out with cheesecloth and cotton balls for further filtration.

The water obtained is much neater than the first and is is free of smell.

Therefore, contaminated water can be made purer by filtration.

Composite volcanoes are explosive, towering giants. Shield volcanoes quietly produce broad, massive structures through lava flows. Cinder cone volcanoes are the smallest and simplest, but still pack a volcanic punch. A caldera is a large depression formed when a volcano erupts and collapses. Lava plateaus are extensive areas of flood basalt which are formed by the extensive eruption of basaltic lava over a large area.

1. A food chain is a single pathway connecting a producer with several levels of consumers. In a typical marine food chain, dinoflagellates convert energy from sunlight into food through photosynthesis and store it in their tissues.

2. They would starve and die unless they could move to another habitat. All the other animals in the food web would die too, because their food supplies would have gone. The populations of the consumers would fall as the population of the producer fell.

have a good day!

The flow of energy in a marine food web include the following:

Plankton⇒shrimp⇒ salmon⇒ seals⇒ whales

A food web comprises of food chains which are interconnected and also

explains the flow of energy between organisms in the ecosystem.

In the marine ecosystem, the plankton which are plants are the primary

producers while the whales are the tertiary/quaternary consumers as they

are at the top of the web.

Removing an organism from a food web can impact the entire ecosystem

by reducing the number of organisms and options available for food. It can

increase or decrease the population of organisms which they have direct

relationship with.

The process of neurulation, which takes place between weeks three following conception, allows the embryo to form the components that will one day become the nervous system. It's important to regulate body functions.

The neural crest gives rise to the development of structures in the periphery. At this stage, the early nervous system resembles nothing more than a straightforward tube. It begins from the front of the embryo and continues all the way around to the back. Beginning at day 25, the anterior end will develop into the brain, while the posterior portion will develop into the spinal cord.

The brain is the organ that is responsible for controlling every function of the body. The brain is connected to the rest of the body through the spinal cord, which travels down the back. It contains nerves that are similar to threads and branch out to every organ and area of the body. Messages are transmitted to and from the brain via this network of nerves, which connects the brain to various regions of the body.

Answer: The mutation could cause it to adapt to the environment better, pick up food better, or even become almost totally different to the others because of how different it is.  changes in the environment determines which organism lives. Some mutations seem to happen spontaneously without any outside influence. They can occur when mistakes are made during DNA replication or transcription. Other mutations are caused by environmental factors. Anything in the environment that can cause a mutation is known as a mutagen. Mutations can occur during DNA replication if errors are made and not corrected in time. Mutations can also occur as the result of exposure to environmental factors such as smoking, sunlight and radiation. ... Mutations contribute to genetic variation within species.

The direction of prevailing winds and convection currents in the Northern Hemisphere and how to label them.

Prevailing winds in the Northern Hemisphere generally blow from west to east due to the Coriolis effect. This means that winds move clockwise around areas of high pressure and counterclockwise around areas of low pressure. The prevailing winds are known as the westerlies.

Convection currents in the Northern Hemisphere are driven by temperature differences between the equator and the poles. Warm air rises at the equator and moves towards the poles, while cold air sinks at the poles and moves towards the equator.

This creates a convection current that moves from the equator to the poles in the upper atmosphere and from the poles to the equator in the lower atmosphere.

To label hot and cold air on your convection currents, you can draw arrows to show the direction of movement and label them accordingly. Hot air rises at the equator and cold air sinks at the poles, so you can label the arrows with "hot" and "cold" respectively.
