Ecosystem and pond,
not sure though but good luck !
Answer:
Option 1, a charged end and a noncharged end
Explanation:
Complete question
If a small droplet of ordinary fat is suspended in water, the fat molecules form a "ball of spaghetti" with no particular orientation. But if a droplet of phospholipid molecules is put in water, all the molecules point outward, toward the water. Phospholipids are forced into this orientation because phospholipids have _____
- a charged end and a noncharged end
- three fatty acid molecules, all pointing in different directions
- two fatty acid molecules pointing in different directions
- both a saturated fatty acid and an unsaturated fatty acid
- two charged ends
Solution
The structure of phospholipids consists of the following groups and molecules –
a) A glycerol molecule
b) Fatty acids (2 in numbers) – It is hydrophobic as it is uncharged and non polar in nature
c) Phosphate group (with alcohol) – It is hydrophilic as it is negatively charged and polar in nature.
When the phospholipids are placed in water, the molecule rearranges itself in a way that the hydrophobic head face inside and the hydrophilic head face outside thereby forming micelles.
Hence, option 1 is correct
Answer: Because The potential energy you build going up the hill can be released as kinetic energy — the energy of motion that takes you down the hill. Once you start cruising down that first hill, gravity takes over and all the built-up potential energy changes to kinetic energy. Gravity applies a constant downward force on the cars.Potential energy is the energy an object has as a result of its position. Potential energy is stored energy that has not yet been released. Gravitational potential energy is potential energy that results from an object's position in a gravitational field, and is equal to the object's weight multiplied by its height.
hope this helps have a nice day❤️
Explanation:
The series of canals used to transport materials throughout the cytoplasm in the cell is Endoplasmic reticulum. It comprises of the rough endoplasmic reticulum, with the ribosomes attached to its surface and the smooth endoplasmic reticulum( no ribosomes attached)
Deforestation is people cutting down whole forests of trees, andmaking it even less likely for humans to survive. Trees supplyoxygen, absorb carbon dioxide, and hold down the soil from washingaway or making landslides. The destruction and cutting down of forests is often done to clearland for farming, mining, roads, and grazing of cattle. That causesincreased atmospheric CO2 levels, a factor in global warming. The Cutting down and clearing of trees The action or process of clearing forests_ also _The state ofhaving been cleared by forests. Verb. To Clear of Forests or trees . The conversion of forested areas to non-forested lands. e.g. Cutting down a forest to make pastures. the cutting down of trees is called deforestation Deforestation means clearing of forests and using that land forother purposes. defforestation is cutting of trees. deforestation is when rain forests get destroyed and ruined 1. The state of being clear of trees 2. The removal of trees Deforestation occurs to create open space for urban or agricultural use.
