D is the correct answer :).
The four inner planets have slower orbits, slower spin, no rings, and they are made of rock and metal. The four outer planets have faster orbits and spins, a composition of gases and liquids, numerous moons, and rings. The outer planets are made of hydrogen and helium, so they are called gas giants.
Answer:
Plants extract the carbon dioxide from the air and use it in photosynthesis process to feed themselves.
The answer is; Benedict’s reagent
It is used to test for reducing sugars. In presence of these sugars, the reagent, that is blue in color, turns different shaded of red (to brick red), depending on the amount of reducing sugars in the solution. It is important to note that the solution has to be heated.
Answer:
C.The percentage of essential body fat is the same for both males and females.
Explanation:
Among the given statements, only C is incorrect. Typically, on average, women have 5-12% more body fat than men. This has been mainly linked with the female hormones (e.g. oestrogen). Firstly, women can store more fat in their bodies due to the presence of excessive adipose tissues. Secondly, they are suppose to carry a child at some stage of their life, so a better food supply and protection is necessary.
On the other hand, rest of the options are true. Essential body fat is always required by body. It accounts for 3% of total body wight. And, it can be found in organs, bones and muscles at different percentages.
Chemiosmosis is the diffusion of diffusion of hydrogen ions (protons) across a biological membrane via ATP synthetase (a transport protein) due to a proton gradient the forms on the other side of the membrane.
Chemiosmosis is one of the processes by which ATP is synthesized. In Eukaryotes, it take place in the mitochondria during cellular respiration and in the chloroplast during photosynthesis.
The process is called chemiosmosis because the chemical ions move from an area of higher concentration to an area of lower concentration through a semi-permeable membrane, just like water molecules.
