horrorfan [7]

The answer is ‘Life insurance could be denied’. Publishing DNA results could make public genetic predisposition to diseases such as Huntington's disease, cystic fibrosis, and disorders such as Alzheimer's that are caused by environmental factors influence on the respective genetic mutations. This would cause the life and health insurers to evade such individuals since they are considered a liability. This would deny the individuals the right to health insurance.

Which TWO descriptions of plants explain how they contributed to the carbon cycle?
denpristay [2]

Plants stored carbon in their tissues to use as energy and plants took in carbon dioxide and released oxygen through photosynthesis. Thus, the correct option is A and D.

<h3>What is carbon cycle?</h3>

The carbon cycle is the ongoing process through which carbon atoms move back and forth between the atmosphere and the Earth. The amount of carbon in this system does not fluctuate because our planet and its atmosphere are a closed environment. The location of the carbon, whether it is on Earth or in the atmosphere, is continually changing.

Plants use photosynthesis to transport carbon from the atmosphere into the biosphere and move it up the food chain. They make sugar molecules by chemically combining carbon dioxide with oxygen and hydrogen from water using solar energy.

Organisms that originated in a certain geographic region and can only be found in that region are said to be ____.
aleksklad [387]

Organisms that originated in a certain geographic region and can only be found in that region are said to be endemic.

Explanation:

Endemic organisms are taxonomic species (plants and animals) which originates and distributed only in specific geographic regions. This state of evolution is called endemism.

They are said to be native or indigenous to that particular region which can be an ecological habitat, an entire nation, an island, a mountain range etc. Certain parts are known for majority of their species being endemic like St. Helen Island, New Caledonia Island, Hawaiian Islands, Southern regions of Africa, and Australia.

The species becomes endemic to a particular region because of the presence of certain bio-geographical environmental qualities of that habitat which are favorable to that species.

When these conditions become unfavorable, then species becomes restricted leading to endangerment or extinction of the species.

Examples:

  1. Kangaroo - Australia
  2. Nilgiri Tahr, - Nilgiri Hills, India
  3. The Redwood trees of West Coast of the USA
  4. Plants like kalo, sumac of Hawaii
