Answer:
Savannahs
Explanation:
Savannahs are usually large areas of open land with few trees. This area is different from deserts because they receive more rain which allows grasses to grow, unlike desserts.
There are 46 atoms of hydrogen inside the cholesterol.
The formula of cholesterol is C27H46O, meaning that besides hydrogen it contains 27 atoms of carbon and one atom of oxygen.
Cholesterol can be found in large concentrations within the liver, spinal cord, and brain providing the stability of the cell membranes.
Answer:
The correct answer is- facilitated diffusion
Explanation:
In facilitated diffusion molecules(solutes) are moved from area having a high concentration of solute towards the area having low solute concentration through a semipermeable membrane with the help of specific proteins is called facilitated diffusion.
As molecules move along the concentration gradients so no energy consumption is required in facilitated diffusion. Transport proteins like channel proteins are used to transport the molecules across the cell.
The rate of transport is higher in facilitated diffusion than simple diffusion. Polar and charged molecules can be diffused by facilitated diffusion.
1. Animals depend on plants to keep them alive is Plants are producers they take energy from the sun, nutrients from the earth, and water to grow and have their flowers, seeds, and berries.
They also release oxygen, which all animals, including humans, need to stay. Animals are consumers and they all depend on plants for survival.
2. carbon dioxide and water reach the chloroplasts in leaves is Basically the roots consume the water and transports it up the xylem, which gets it to the leaves. Carbon dioxide contacts the chloroplasts in the leaves via a stomata
3. Two pieces of evidence that show that plants cannot make their own food without light. When plants lack light, they don't deliver chlorophyll (the green pigment in plants), and plants can turn pale green to yellow to white. Plant stems become “leggy,” meaning stems become long and thin and appear to be advancing toward the source of light.
- The photosynthesis is the only method for synthesizing food. It is commonly believed that about 717.6Kcal energy is required to prepare just 10g of glucose. No energy input no metabolism and therefore no food.
<h3>How are leaves tested for starch?</h3>
The existence of starch in leaves can be tested by the Iodine test. When we remove chlorophyll from the leaf by cooking it in alcohol and then placing two drops of iodine solution, it is a color change to blue indicates the existence of starch.
