PLEASE HELP I WILL GOVE THE BRAINIEST AND PLEASE, I DONT WANT NO LINKS
Degger [83]

Answer:

The Visible Light Spectrum and the differences in wavelength and appearance.

Explanation:

I stated this by using the concept of the visible light spectrum. As indicated already in reference to the statements provided, you are observing what is known as the visible light spectrum. This is indicated because the visible light spectrum obtains all the colors of the rainbow and not only that but the statements even use key terms such as wavelengths and different color components. Therefore, signifying that you are looking at the visible light spectrum and observing it on an appearance based observation based on background facts and scientific knowledge. To further evaluate the visible light spectrum in terms of wavelength, both statements A and D provide information regarding the differentiation within wavelengths based on the color in which one perceives. Whereas B and C simply state scientific facts about how the rainbow appears.

<h2>Answer is "long chain fatty acids"</h2>

Explanation:

  • A fatty acid is one of the major components of a triglyceride, which is a form of lipid that is used in the body to store energy. A lipid is just a type of molecule that includes, among other things, fatty acids. Triglycerides are a secondary energy source that the body can use in the event that there is not enough sugar (our primary energy source) in the system. While fatty acids vary in terms of chemical characteristics, they all have some basic qualities in common.
  • Hence the right answer for the fill up the blank is "long chain fatty acids"

LenKa [72]
<h2>e) option is correct </h2>

Explanation:

  • Cap Z is a capping protein which controls the access to the free barbed ends of actin filaments and is therefore a major factor affecting actin filament elongation
  • Capping proteins have a high affinity for barbed ends and their micromolar concentration in the cytoplasm ensures that most barbed ends are capped
  • Depletion of capping protein promotes increased filament assembly away from the leading edge in migrating cells
  • Cap Z helps favor actin assembly by preventing the loss of actin subunits to the barbed end and also prevent annealing of severed or de-branched filaments and they block both the association and dissociation of subunits at the barbed end
