The first one: both mitochondria and chloroplsats have their own DNA.
Answer:
I don't know if this is what you mean, but here is what I read it as:
1. can be simplified to "1"
2. can be simplified to "3/4"
3. cannot be simplified so it remains "3/4"
4 can be simplified to "1/2"
1. The best answer is Stomata takes in carbon dioxide and release oxygen. Photosynthesis is the process that take place in the leafs of green plants where chlorophyll absorbs sunlight and converts the energy from the sunlight to chemical energy. The process produces simple sugars and oxygen, oxygen is either released to the atmosphere or used in cellular respiration. Simple sugars (glucose) are stored as glycogen and used as an energy reserve.
2. The statement is true. Water and carbon dioxide are are raw materials of photosynthesis. Water is broken down in the first stage of photosynthesis using sunlight to produce oxygen and hydrogen ions. The second stage of photosynthesis involves carbon dioxide fixation producing simple sugars
(glucose).
3. The equation that supports the conservation of energy is;
6CO2 + 6H2O + light = C6H12O6 + 6O2
This is the process of photosynthesis that involves use of carbon dioxide and water to produce glucose and oxygen.
Six carbon atoms are used to generate another six carbons in glucose, hydrogen atoms and oxygen atoms taken in remain the same in the products.
Explanation:
a platypus is the only mammal to lay eggs
The answer is option 3 because people with sickle cell anemia have abnormal hemoglobin molecules that is called hemoglobin S, which stick to one another and form long, rod-like structures. These structures cause red blood cells to become stiff and shape into sickles or crescent moons.
Hope that helps!
