Answer:

Phospholipids are amphipathic molecules. This means that they have a hydrophilic, polar phosphate head and two hydrophobic fatty acid tails. These components of the phospholipids cause them to orientate themselves, so the phosphate head can interact with water and the fatty acid tails can't, hence forming a bilayer

Which of the following is the coenzyme that functions as an electron carrier in photosynthesis?
faltersainse [42]

Answer:

The correct answer is C. NADP⁺

Explanation:

NADP+ is the coenzyme that acts as the electron carrier during the photosynthetic process. The electron that is released from the splitting of water pass through the electron transport chain and at the end of the chain the electron is received by an electron carrier called NADP+.  

So this passing of electron causes the transport of H ions in the thylakoid lumen from the stroma and when these ions come back through ATP synthase it forms ATP. Then these NADPH and ATP are used in the Calvin cycle to fix the CO2 into complex form. Therefore the correct answer is C. NADP⁺.

Approximately 2 million years ago the genus Australopithecus gave rise to a new genus, Homo. Today, we retain the genus as Homo
nydimaria [60]
There was two of the same question, but here is the answer again with a little more depth.

D - spine alignment and foot size.

It was only the late Australopiths that had an S-shaped spine. This allowed for them to be bipedal, that is, the ability to walk on two legs as we do. This is because the S-shaped spine allowed them to balance when they were standing. The late Australopiths also have shorter and less flexible toes. These smaller, but sturdier feet made pushing off the ground much easier - aiding in their bipedalism.

Put the following structures in order of superficial to deep based on their descriptions:
AleksandrR [38]

Answer:

The right order is 3, 1, 2.

Explanation:

The most superficial layer is 3, which describes the Cornea. This layer, which is first hit by light, is made of transparent and resistant fabric. It protects the eyeball from trauma and contamination and helps shape the globe and refract light.

Then, the layer described as 1 is the pigmented part that has melanocytes, which may be the uvea that consists of the whole of the iris, choroid membrane and ciliary processes.

Finally, the deepest layer in this question describes the lens, which is a gelatinous biconvex lens. This important structure enables the eye to focus on objects.
