Answer:
Cyanobacteria are aquatic and photosynthetic, that is, they live in the water, and can manufacture their own food. Because they are bacteria, they are quite small and usually unicellular, though they often grow in colonies large enough to see. They have the distinction of being the oldest known fossils, more than 3.5 billion years old, in fact! It may surprise you then to know that the cyanobacteria are still around; they are one of the largest and most important groups of bacteria on earth.
Answer:
B- Photosynthesis
Explanation:
Chloroplasts are <em>chlorophyll-containing, eukaryotic cell structures</em> that function in photosynthesis by absorbing energy from sunlight, combining this energy with water and CO2 to convert them to sugars . This cell structure is known as a plastid. The sugars produced, are important for the survival of the plant.
Chloroplasts reproduce on their own, independent of the whole cell because they contain their own DNA. Plant chloroplasts are located in guard cells in plant leaves. Closely linked to these guard cells are tiny pores called stomata, which allow gas exchange required for photosynthesis.
Photosynthesis occurs in two stages:
- The light reaction stage
- The dark reaction stage
The Light reaction stage takes place in the presence of light. Clorophyll converts light into chemical energy in the form of ATP and NADPH. Both molecules produced, are used in the dark stage to produce sugar.
In the dark reaction stage, the stroma, containing enzymes, facilitates reactions leading to the production of sugars from ATP and NADPH. This process is also called the carbon fixation stage. The sugar produced can be stored in the form of starch for other processes such as respiration.
Answer:
Answer is A. Expression of Cadherin gene in the cell that do not normally adhere to each other( or have low adhesion function).
Explanation:
Not that, the level of Cadherin expression influences the streght of adhesion and the type of Cadherin expressed, in determining the specificity and property of interaction.
Answer:
aerobic
Explanation:
has far more energy therefore produces more ATP
Answer:
Professional gardeners often soak seeds in hydrogen peroxide before planting them in order to increase the germination percentage or to reduce germination failure. When the seeds are soaked in hydrogen peroxide, the seed coat becomes soft and enzymes present in the seed becomes active. Due to soaking of seeds, the seed takes less time to germinate. So that's why gardeners uses this method.
