D because they evolved into the special that are current now

Fossils of species that no longer exist but are ancestors of current species have been found in rock layers. Thus, the correct option is D.

What are Fossil fuels?

A fossil fuel is a hydrocarbon-containing material which is formed naturally in the Earth's crust from the remains of dead organisms such as plants and animals which are extracted and burned as a fuel. The main fossil fuels which are present in the earth's crust include coal, oil, and natural gas.

The evolution of species is easily confirmed by the presence of fossils of the most diverse species of the living beings in the world. This is because, fossils are the records of species which do not currently exist, however there are existed millions of years ago and are similar to the current species, being their ancestors.

Therefore, the correct option is D.

Arctic ice retreat is threatening many species in this ecosystem. Their resources are being cut and they are needing to find new ways to survive. Do you think in your lifetime you will see drastic effects to the species in this ecosystem and why? Will that affect other ecosystems?

Answers

Answer:

no

Explanation:because they will find new ways to survive in the environment

Answer:

We are already seeing drastic effects to the ecosystem and it's wide assortment of species. Animals such as polar bears, and seals are losing their breeding and hunting grounds. Polar bears in particular are losing their ways to catch seals for food and interbreeding with grizzly bears. Fish and whales from warmer parts of the world are starting to move up north and are becoming invasive. Most importantly, since cold water from the melting ice are mixing with ocean currents, global climates and weather systems are changing course. Ultimately, in about 500 years, there could be a large Global Climatic Shift that may put us into another Ice Age.

Which of these locations is most likely to experience moderate climate throughout the year?

Answers

Answer:

b

Explanation:

The location that is most likely to experience moderate climate throughout the year is C.

The location C of the map will experience moderate climate because it is a coastal region of the map.

Moderate climate weather is described as a weather condition that occurs during the day, as cool air from sea rush towards the land and during night, as cool air from the land rush towards sea.

Because location C is a coastal region which means that the location is surrounded by land which better absorbs and radiates heat much faster than sea.

Therefore, the location that is most likely to experience moderate climate throughout the year is C.

State reason(s) why ash should or should not be used in making compost

Answers

Answer:

Fireplace ashes for compost can be used to help maintain the neutral condition of the compost. It can also add nutrients to the soil. Decomposing materials in the compost pile can become somewhat acidic and wood ash can help offset this, as it's more alkaline in nature.  But Adding too much ash to the pile can be detrimental to the makeup of the compost because of its alkalinity. Ashes tend to raise the soil pH, so you shouldn't use it directly on plants, especially acid-loving ones like rhododendrons, azaleas, and blueberries. Also, in high amounts, wood ash can inhibit plant growth by restricting nutrients, like iron.
