A team of scientists are studying three different layers of sedimentary rock to learn about a particular reptile species. In the

layer of rock that is closest to the Earth's surface, the reptiles' teeth fossils are found to be short and straight. In the layer below, the reptiles' teeth fossils are found to be long and straight. In the layer below that, the reptiles' teeth fossils are found to be long and curved. Based on this information, the reptiles today most likely have

The answer is <u>short, straight teeth.</u>

<u>Sedimentary rock forms in layers over time. As time passes, new layers form upon the older layers. This means that as time passes, fossils are buried deeper and deeper in the ground. Therefore, fossils found in higher layers of sedimentary rock are newer than fossils found in lower layers of sedimentary rock. </u>

<u> </u>

<u>Since the layer of sedimentary rock that is closest to the Earth's surface contains short, straight teeth fossils, the reptile species is most likely to have short, straight teeth today. </u>

Which of the following are functions of lipids? Select all that apply
tester [92]

Answer:

A) Lipids are a source of stored energy

Explanation:

Whereas carbohydrates provide a readily available source of energy, lipids function primarily as an energy reserve. The amount of lipids stored as an energy reserve far exceeds the energy stored as glycogen since the human body is simply not capable of storing as much glycogen compared to lipids.

jok3333 [9.3K]

Answer:

348.75 individuals, however you may need to round

Explanation:

To solve this problem, you need to think of the proportions you are given. Since she marked 45 fish in the beginning, and assuming none died, you can assume that there are 45 marked fish in the whole population. Therefore, when she takes the sample of 62 and sees that there are 8 marked fish, a good strategy is to take that proportion and use it to solve for the population like so:

8(marked fish in sample)/62(total in sample) = 45(total marked fish)/x(total population. Next cross-multiply 45 * 62 and 8 * x and set them equal to each other, getting you to the equation 2790 = 8x. Finally, to find x, the population size, divide 2790 by 8 to get x= 348.75.

The Citric acid cycle occurs in the mitochondria. There are nine biochemical reactions involved in the Citric acid cycle, and th
Sauron [17]

Answer:

. 2C- acetyl Co-A from the link reaction  enters the kreb Cycle to combine with 4 Carbon Oxaloacetate to form 6-  Citrate

The Citrate forms intermediate Isocitrate, which eventually formed  6-C alpha ketoglutarate.

The alpha-ketoglutarate forms the intermediate succinyl-Co A, which later formed  5C-succinate.

5C -Succinate  forms 4C-fumarate, the latter formed 4C-malate- which eventually formed 4C-oxaloacetate.

The 4C of these compounds is fixed, to ensure constant availability of 4C of oxaloacatate for 2C Acetyl -CoA to bind it for the cycle to continuously occur for production of first product Citric Acid  from which other products are  formed from.
