Explanation:
Answer: D. Plants do not eat, so both chloroplasts and mitochondria are needed to make enough energy for plants to grow.
Explanation: Option A is invalid since plant cells do use ATP. Option B is invalid since animal cells don't make their energy with chloroplasts. Option D is the most realistic one since chloroplasts in the plant are the ones that make the food for the plants, plant doesn't have a "mouth" so they depend on chloroplast to make food.
The correct answer is D. Both absorb carbon dioxide from the atmosphere.
The process of photosynthesis is carried out using atmospheric carbon dioxide by green plants. Many gases including carbon dioxide are dissolved in seawater. Some of the carbon dioxide gas remains in dissolved state but most of the carbon dioxide is reacts with water to form carbonic acid. Dissolved gases in seawater make balance with atmosphere by mixing of the surface by wind and waves. Therefore, both photosynthesis and sea water take carbon dioxide from the atmosphere.
The correct answer is angioplasty.
<span>
Angioplasty is one of the treatments after heart attack including special tubing with an attached deflated balloon. The tube is threaded up to the coronary arteries. Angioplasty is usually combined with the placement of a small tube called a stent which helps to restore the flow of blood through the artery and decreases its chance of narrowing again.</span>
