Answer:
Chloroplasts
Explanation:
Chloroplasts work to convert light energy of the Sun into sugars that can be used by cells.
Answer:
Starch is an example of a simple carbohydrate.
Explanation:
Carbohydrates are made up of three components: fiber, starch, and sugar. Fiber and starch are complex carbs, while sugar is a simple carb. Depending on how much of each of these is found in a food determines its nutrient quality.
If you bake your potatoes wrapped in aluminum foil and then leave them to cool down without unwrapping the foil, you are in danger of letting dangerous bacteria grow on them. One of these dangerous pathogens is the Clostridium botulinum, a bacterium that produces toxins and causes botulism. This pathogen thrives in low-oxygen (anaerobic) environments, like the one created in the aluminum foil. Also, it can survive high temperatures by forming heat-resistant endospores.
Answer:
B. DNA unzips before step 1.
Explanation:
This question is describing the process of gene expression, which is made up of two major stages namely; transcription and translation. Transcription is the process by which mRNA is synthesized from a DNA template while translation is the process where protein (amino acid sequence) is produced using the mRNA transcript.
This stages of gene expression has been summarized in the steps listed by Shura. However, prior to the formation of an mRNA molecule in step 1, the double stranded DNA has to unwind i.e. separate into single strands as initiated by the enzyme RNA polymerase. Therefore, the list should read as follows:
- DNA unzips
- A strand of RNA is made.
- RNA leaves the nucleus.
- RNA moves to the ribosome.
- A protein is made.
