Which of the following is something you should do after severe weather occurs?
Clean up flood waters.
Cleaning up will always be the step after the storm. Assuming they're talking about a hurricane, then the flood waters would need to be cleaned up. Besides for the last choice (which is utterly ridiculous!), those should be before and during the storm.
Depending on where you live and what kind of sever weather you encounter, a safety plan for you and your family is a must. You should always know where you can go to be safe from the elements and what to do during severe weather.
During the storm, stay away from windows. This pertains to all weather, including those with wind and lightning. Wind could blow debris that could possibly shatter glass and hurt you or others. With lightning, if it strikes the window, it will shatter it, merely from the heat of the contact.
Explain how parts of a whole system contribute to the function of a whole system?
Every organ system is made up of parts that contribute to the functions of the whole system.
How do parts of the system contribute to the function of a whole system?The human body is made up of many parts that have specific functions that come together to make up the whole organ system. Scientists divide them into different parts and different organ systems to better understand the individual functioning of the specific parts.
A body system is made up of body parts that work together to carry out a particular function. For example, the integumentary system that consists of skin, hair and nails that integrate together to carry out the function of protecting the body.
Another example is that of the immune system that is made up of complex organs, tissues and cells like the WBCs that form a network among each other to carry out the function of recognizing antigens and destroying them to keep infections at bay.
Two or more body systems also work together to carry out a certain function. For example the respiratory system and circulatory system come together to provide oxygen to the cells of the body and remove carbon dioxide.
This is how parts of the whole system contribute to the function of the whole system.

How the dorsal/ventral pattern is initially established in drosophila development
The dorsal/ventral pattern is initially established in drosophila development by the gradient of a transcription factor called dorsal protein.
What do you mean by Dorsal protein?Dorsal proteins are synthesized after fertilization, when dorsal is translated, it forms a complex with a protein known as cactus in the cytoplasm.
The dorsal/ventral axis in the Drosophila is determined by morphogenesis which is established by 12 maternal effect genes along with the dorsal and cactus.
Therefore, the dorsal/ventral pattern is initially established in drosophila development by the gradient of a transcription factor called dorsal protein.

Peppered moths live on lightly colored trees, lay around 100 eggs and don’t live longer than a year. How does that help them adapt and survive?
Answer:
They camouflage
Explanation:
The peppered moths adapt to their surroundings. They blend in with their surroundings to avoid being eaten by their predators. Blending in with their surrounding also helps them to sneak up on and catch their prey.
I'm not too sure why they lay 100 eggs at a time but i think it's because the parents want to increase the survival of their eggs. Eggs sometimes are eaten by other animals and the parents want at least a few to survive.

Why is the sustainability of water for the future generations to come so important
Answer:
The sustainability of water for future generations is important because water is the source of life, the substance that enables all living things to survive and develop. Water is at the core of sustainable development and is critical for socio-economic development, healthy ecosystems, and for human survival itself. It is vital for reducing the global burden of disease and improving the health, welfare, and productivity of populations. Therefore, water must be sustained for future generations in order to protect and preserve the environment and to move towards a sustainable development model.
