Answer:
The star is traveling <em>towards</em> the earth.
Explanation:
Space experts arrange stars into groups as per their shading and the composition. This star arrangement framework goes this way: O, B, A, F, G, K, M in which O star is blue and is very hot and <em>M stars are red</em> and the coolest and most basic stars in the Universe.
From the color of the star we can infer that as the star is appearing red it is inferred that the star is an M star and it is traveling towards the earth.
The answer is; Choice D
ABC transporters are transmembrane proteins that enable active transportation of substances across the cell membrane. The protein is important in the movement of substances against their concentration gradient using ATP energy. ATP binding causes it to change conformation and bind the molecule being transported.

As "nurse" cells for neurons in the brain parenchyma, astrocytes are resident glial cells produced from neuroectoderm.
How astrocytes become pathological?
- Recent research has identified astrocytes as major disease-propagating agents in mutant human superoxide dismutase 1 (mSOD1)-mediated amyotrophic lateral sclerosis (ALS).
- However, due to the widespread expression of mSOD1 throughout the CNS of the investigated rodent models, in vivo examination of a specific astrocytic effect in amyotrophic lateral sclerosis has proven challenging.
- In order to understand how mutant astrocytes affect WT MNs and other cell types (microglia and astrocytes) in an in vivo environment, we transplanted SOD1(G93A) glial-restricted precursor cells into the cervical spinal cord of WT rats.
- SOD1(G93A) glial-restricted progenitor cells that were transplanted survived and successfully differentiated into astrocytes.
