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.

coldgirl [10]
Alright, from what you're telling me. (And trust me, I love neuroscience).

This patient most likely has a lesion/damage to his Brocha's or Wernicke's area. A neurological examination will have to be conducted in order to determine which one, test his language comprehension in order to rule out Wernicke's. If you're looking for a more general diagnosis, I'd roughly call it the Temporal lobe.

Scientists are now studying human DNA in labs all over the world. Which are current goals for the scientists at these labs? Sele
Virty [35]

Answer:

B. identifying the regions of human DNA that are transcribed into RNA

C. identifying the regions of human DNA that bind to proteins

D. analyzing the regions of human DNA that vary among individuals

Explanation:

The double helix structure of the deoxyribonucleic acid (DNA) molecule was characterized and published in April 1953 by Francis Crick and James Watson. Moreover, the Human Genome Project was a project aimed at completing mapping and sequencing of the human genome. This project was completed and published in April 2003. Nowadays, scientists are focused on identifying which genes are expressed (i.e., transcribed into RNA) in specific cell types/tissues. For this purpose, it is imperative 1-to identify the promoter and enhancer regions that bind to specific proteins (transcription factors) in order to activate gene expression, and 2-to understand how genetic variation is related to gene expression patterns in specific cell types and/or in response to specific environmental stimuli.
