Explanation:
C. They make it more fluid
Lipids are composed of fatty acids which form the hydrophilic head and glycerol which forms the hydrophilic tail; their arrangement can give these non-polar macromolecules hydrophilic and hydrophobic properties. 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.
The hydrophilic heads of the bilayer are attracted to water while their water-repellent hydrophobic tails face towards each other- allowing molecules of water to diffuse across the membrane along the concentration gradient.
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. Cholesterol, which is comparatively rigid, anchors other molecules attached to the membrane, maintain membrane stability or structural integrity and aid in separating some lipids, helping with membrane fluidity at low environmental temperatures.

A change in the base pair sequence.
The answer is <u>"D. They are both arm exercises".</u>
A barbell curl refers to a pull-type, segregation practice which works essentially your biceps, yet in addition trains muscles in your lower arms and shoulders somewhat, as well. You can perform barbell curls by grasping a barbell with an underhand grasp, and with your hands isolated by a shoulder-width separate.
A dip is a compound, push-type practice which works countless in your chest, shoulders, and arms at the equivalent time. Depending on the sort of preparing routine you're utilizing, you might need to utilize dips to point out extraordinary your chest muscles. You can do this by performing Chest Dips in which you fit your body forward while dipping.
Answer:
750
Explanation:
With the f1 generation all being red flowers we can conclude that Red is dominant (R) and white is recessive (r).
This leads to the f1 generation having Rr. If you breed two Rr together you get
1 RR
2 Rr
1 rr
75% of the f2 will have red flowers. So if you take 1000 and multiply it by .75 you will get 750
Approximately 750 flowers will be Red.
