Answer:

During photosynthesis, plants take the water from the soil, and the carbon dioxide from the air, and they make sugars out of it. When plants have the right balance of water, air, sunlight and nutrients, their cells grow and divide, and the whole plant gets bigger and bigger. And that's how plants grow.

The fetal skeletal is made of cartilage and eventually turns to bone in a process called ossification. Given what you know about

RoseWind [281]

Answer:

Explanation:

Based on what is known about the fetal skeleton and the ossification process it can be said that this occurs due to babies having more of the osteoblasts bone cells. These cell's main function is to lay down new bone material, this therefore creates a thicker harder bone which allows for proper support so that the body can continue growing and become stronger overall.

What is the make-up (structure) of the plasma membrane? what makes the plasma membrane selectively permeable? how are the phosph

devlian [24]

Lipid bilayer model was proposed for its structure but it was modified and new structure is according to fluid mosaic model. Plasma membrane is selectively permible as it selects small molecules like lipid etc (composition is also of lipid and as solubility principle like dissolve like) so large and charged molecules like plasma and ion can't pass through it. Lipid are in form of layer so at the chain when ever other phosphate group attach the place conjugate molecule (phospholipid ) formed

In a plasma membrane, how do the tails of the phospholipid molecules line up?

Nezavi [6.7K]

They are sandwiched between two layers of heads. Recall that the heads are hydrophilic therefore they will always be on the outside and the tails are hydrophobi therefore they willl always be away from water, there fore sandwiched. I'm a bio major, hope I helped :)
