Question 1): Photosynthesis and cellular respiration are often described in two ways: 1) they are chemically opposite; and 2) th

ey have a relationship to each other. Explain what these two statements mean. Be sure to include the specific substances used and released by each process. Question 2) Your skin is constantly producing new cells through cell division. How does this happen? During interphase, how does a cell prepare for division? Describe cell division, including the processes of mitosis and cytokinesis. Be sure to describe the mitotic steps. Question 3) Mitosis and meiosis are similar processes, but they have some very important differences. Explain how mitosis and meiosis are alike and how they are different. Provide at least two similarities and three differences. ( Please Do Not Repost Someone Else's Answer that is on Brainly Or Any Other Websites) Will Mark Brainliest . ​

why would having both polar and nonpolar properties in a protective boundary be advantageous for the cell?
Reika [66]

Explanation:

The polar nature of the membrane’s surface can attract polar molecules, where they can later be transported through various mechanisms. Also, the non-polar  region of the membrane allows for the movement of small non-polar molecules across the membrane’s interior, while preventing the movement of polar molecules, thus maintaining the cell’s composition of solutes and other substances by limiting their movement.

Further explanation:

Lipids are composed of fatty acids which form the hydrophobic tail and glycerol which forms the hydrophilic head; glycerol is a 3-Carbon alcohol which is water soluble, while the fatty acid tail is a long chain hydrocarbon (hydrogens attached to a carbon backbone) with up to 36 carbons. Their polarity or arrangement can give these non-polar macromolecules hydrophilic and hydrophobic properties i.e. they are amphiphilic. Via diffusion, small water molecules can move across the phospholipid bilayer acts as a semi-permeable membrane into the extracellular fluid or the cytoplasm which are both hydrophilic and contain large concentrations of polar water molecules or other water-soluble compounds.

Similarly via osmosis, the water passes through the membrane due to the difference in osmotic pressure on either side of the phospholipid bilayer, this means that the water moves from regions of high osmotic pressure/concentration to regions of low pressure/ concentration to a steady state.

Transmembrane proteins are embedded within the membrane from the extracellular fluid to the cytoplasm, and are sometimes attached to glycoproteins (proteins attached to carbohydrates) which function as cell surface markers. Carrier proteins and channel proteins are the two major classes of membrane transport proteins; these allow large molecules called solutes (including essential biomolecules) to cross the membrane.

What exercise requires that the knees always stay in line with the toes throughout the jumping phases of takeoff and landing?
Tasya [4]

Answer:

The correct answer is - power step-ups.

Explanation:

Power step up is an exercise that involves an individual to stand upright and lift ur chest and tuck chin in. Put one leg on box or step and forcefully push that leg into the air and put the leg softly on the box or step and again push this leg now in air forcefully and softly put another leg on the box, repeat this again and again.

This exercise helps to keep the knee in line with the toe through the jumping of landing and take off.

Thus, the correct answer is - power step-ups.
