Apex Environmental Science

Answers

Less wildlife habitat is a possible cost of clearing forests.

Environmental cost of clearing forests:

If forests are clearedor even disturbed, they release carbon dioxide and other greenhouse gases. Forest lost and damage is the cause of around 10% of global warming.

The lost of trees can cause climate change, desertification, soil erosion, fewer drops, flooding, increased greenhouse gas, less wildlife habitat.

Wildlife habitat depends upon the forest. If forest will loss wildlife habitat will also be less. It will surly effect on nature.

The correct answer is option D.

Flowers are an important part of __________ reproduction in strawberry plants. A) abiotic B) asexual C) budding D) sexual

Answers

Answer:I had this question on usa test prep its b

Explanation:

Strawberry plants can reproduce several ways. A strawberry plant's main stem is called a crown. This crown produces spirals of leaves, runners, and flowers. The flowers become the strawberries that we love to eat. When days are long and warm, the plant produces runners. Runners are offshoots of the parent plant, sometimes called stolons. These runners are stems growing out from the crown along the ground. The runners grow roots and along the runner, "daughter plants" can develop. Most commercial strawberry growers use runners to produce new plants.
