Hey!
Your answer is B (You're correct)
Have a great day!
Answer:
It lacks a wall thus use the contractile vacuole to collect and expel excess water from the cell.
Explanation:
- The contractile vacuole regulates the quantity of water inside a cell through a process known as osmoregulation.Osmosis constantly drives water in the cell since it is enclosed by a semipermeable membrane that can not keep the water out thus it is needed to prevent rupturing of the cell due to excess water in the cell.
Answer:
Soda can be prepared using sucrose, carbon dioxide gas, concentrated juices from different fruits in water.
For making soda, concentrated juices with required fruit flavor in water is used. The temperature of water should be low. Then required amount of sucrose is added. At the end, carbon dioxide is added to the tanks and pump it in under pressure before bottling which act as carbonic acid and add acidic flavor to the soda.
<em>The temperature should remain low because carbon dioxide gas dissolve more easily at low temperature and high pressure also support carbonation of carbon dioxide gas.</em>
Maintaining low temperature is beneficial to minimise the cost of energy and CO2 emission as well.
Answer:
<em>The correct option is A) Active transport moves substances against the concentration gradient.</em>
Explanation:
Active transport can be described as the movement of molecules against a concentration gradient i.e from an area of lower concentration to an area of higher concentration.
Facilitated diffusion can be described as the movement of molecules guided by other molecules such as integral proteins. These kinds of movements are a type of passive transport as the molecules move along the concentration gradient from an area of higher concentration to an area of lower concentration.
Answer:well it’s The Sun is the major source of energy for organisms and the ecosystems of which they are a part. Producers such as plants, algae, and cyanobacteria use the energy from sunlight to make organic matter from carbon dioxide and water. This establishes the beginning of energy flow through almost all food webs, and they are five main sources of energy - Solar energy from the sun - GEOTHERMAL-WIND - Biomass from plants - Hydropower from flowing water and from crystalline, the animals have sun has a main energy also from nutrients
Explanation:from scientifical viewing
