Fossilized stromatolites
Cerrena [4.2K]

Answer:

(B) resemble structures formed by bacterial communities that are found today in some shallow marine bays.

Explanation:

Extant stromatolites represent real "living fossils" for they are decendents of ancient forms that are associated with one of the first living forms on earth. Particularly, stromatolites are real bacteria communities where the autotrophic organism of the community are represented by cyanobacteria, which live along with heterotrophic bacteria. This clearly indicates that fossilized stromatolites points to bacteria (prokaryotes) as the first living things on earth (dated with not less than 3.5 billion year old)

Nowadays, stromatolites with cyanobacteria allows to reconstruct and understand fossilized forms. These current structures live in shallow marines ambients (e.g. Australia) but also in continental salt flats (e.g. Argentina) where few others bacteria can survive to these extreme conditions (high light exposure and salt concentration).

To analyze the long bones, the femur and the humerus, you looked at bone markings such as condyles, tuberosities and trochanters
inn [45]
<span>When looking over the long bones of the body, I decided to focus on the two largest, , the humerus and the femur. The humerus has a round projection which looks slightly irregular. The femur has more of a rough look to it. The femur is The largest bone of the body connecting to the acetabulum ( hip bone socket) and helps support the weight of the body. It can withstand more pressure than the humerus bone. I think the structural difference in these two bones is what makes the difference in the markings and features.</span>

What ultimately happens to the light energy captured during photosynthesis?
Degger [83]

Answer:

The correct answer is- It is used to produce glucose molecule

Explanation:

Photosynthesis is a process in which light energy is captured by chlorophyll which is then used to convert carbon dioxide and water into glucose. Oxygen is also produced as a by-product in this process.

The light energy is used to split water into oxygen, hydrogen ions and release electrons from it. The electrons pass through many electron carriers through photosystem II and I and ultimately reduce NADH+ to NADPH which is used in the Calvin cycle to produce glucose.

Therefore glucose is produced by the help of light energy captured during photosynthesis.
