The fossils that scientists find and study today formed thousands to millions of years ago. But, you can simulate the process of

fossilization. Follow these steps to model a fossil:
1. Line the inside of the plastic container with plastic wrap.
2. Let the ends of the plastic wrap hang out of the container. The overhanging ends will allow you to more easily lift out your formation when it’s complete.
3. Pour four inches of water into the container. Use a ruler to measure the correct depth.
4. After adding the water, add two inches of sand.
5. Spread the twigs and leaves in a thin layer on the top of the sand.
Stay safe! Use gloves when handling the leaves and when checking the inside of your model during the weeks to come. Wash your hands and gloves when you are done.

Part A
After assembling the materials, record your observations. Describe what the setup looks like and the color of the leaves and twigs. Predict what changes will take place over the next few weeks.

answer below

Explanation:

It starts to get foggy inside the tanks and the leaves are absorbing the water and the leaves are going to hit the sand when they hit the sand they dry out because they have no more water to absorb.

Hope you have a great day and god bless you!!

each of the following molecules is processed by glycolysis to pyruvate. how much net atp is generated starting with each molecul
ki77a [65]

From glucose 2 ATPs are produced.

ATP:

  • One glucose molecule is divided into two pyruvate molecules during glycolysis, requiring two ATP molecules while generating four ATP molecules and two NADH molecules.
  • For the cell to utilize as energy, glycolysis results in a net gain of two pyruvate molecules, two ATP molecules, and two NADH molecules.
  • Glucose breaks down into pyruvate and energy during glycoses
  • From glucose 6- phosphate to lactate 3 ATPs are produced.
  • 4 ATPs are generated from which one is utilized when fructose 6 phosphate is converted to fructose 1, 6- bisphosphate. So the net yield is 3ATP.

From dihydroxyacetone phosphate 2 ATPs are produced.

As the cycle occurs only once either from DHAP or PGAL (glyceraldehyde $3-$ phosphate)

Three irreversible reactions of glycolysis:

Hexokinase

Glucose + ATP$\rightarrow$ Glucose-6-phosphate + ADP

Phosphofructokinase-I

Fructose-6-phosphate + ATP $\rightarrow$ Fructose-1, 6-bisphosphate $+$ ADP

Pyruvate kinase

$\mathrm{PEP}+\mathrm{ADP} \rightarrow$  Pyruvate $+$ ATP

Testosterone is an example of a chemical signal that affects the very cells that synthesize it, the neighboring cells in the tes
saw5 [17]

Answer: Autocrine signal, paracrine signal and endocrine signal.

Explanation:

Testosterone is an example of hormone which shows its effect on different locations of the cells.

The autocrine signal can be defined as the siganals which shows its effect on the cell from where it is being produced. This means a cell targets itself.

Then comes the paracrine signals in which signals acts locally on the cells nearby it. The cells close together to the cells producing chemical signals is being affected.

The endocrine signals can be defined as the effect of the hormone on the distant cells. The signals is produced by the cells somewhere else but is carried through the bloodstream to the distant cells.

All of the three effects is being shown by testosterone autocrine, endocrine and paracrine.

Law Incorporation [45]

Answer:

The bacteria will be evenly distributed on the chain of algae

Explanation:

<em>If the component of white light is not separated by a prism, all the components will be evenly distributed in space and as such, equal amount of each component will go to the chain of algae.</em>

<em>The equal amount of each light component that goes to the chain of algae will ensure that there is equal rate of photosynthesis, and hence, oxygen production in each algae. Consequently, the oxygen-requiring bacteria will spread out evenly on the chain of algae without concentrating particularly on any algae.</em>
