Answer:
B. Many active genes are found in euchromatin, because proteins involved in transcription can easily access these regions of DNA.
Explanation:
Euchromatin is the loosely coiled chromatin and is capable of undergoing the process of transcription. On the other hand, heterochromatin is the highly coiled and compacted chromatin present in its inactive state. Active genes are associated with more loosely packed chromatin, which is the euchromatin. This is due to the fact that the DNA in euchromatin is not tightly packed which in turn allows its interaction with a transcription factor. The tightly packed DNA of heterochromatin cannot interact with proteins requires for gene expression.
Answer:
1.—The (more) variations in forms it can produce.

The patient would take a combination of atovaquone and proguanil. Both combined are effective for the treatment of c<span>hloroquine-resistant malaria.</span>
Answer:
Explanation:
chemical energy
The overall purpose of the light-dependent reactions is to convert light energy into chemical energy. This chemical energy will be used by the Calvin cycle to fuel the assembly of sugar molecules. The light-dependent reactions begin in a grouping of pigment molecules and proteins called a photosystem.
When conducting legal experiments on animals, a researcher needs to obtain consent from the INSTITUTIONAL RESEARCH BOARD.
Each research institution has research board which sees into uses of animals for research purposes, consent must be obtained from the board before experiments involving usage of animals is carried out.
