Final Point ( what are the 3 parts of the cell theory)

Answers

Answer:  All living things are composed of cells.

Cells are the basic units of structure and function for living things.

All cells come from pre-existing cells. Also, organisms grow by “adding on more cells” NOT by increasing the size of their cells.

How does the cell cycle start off?

Answers

Entry to the cycle is made in Gap 1 (G1) phase and this is followed in sequence by a DNA synthesis (S) phase, Gap 2 (G2) phase, and Mitosis (M). After mitosis (M) some cells enter the G1 phase of a new cell cycle whilst others may diverge at the start of G1 into a phase called Gap 0 (zero)

A new cell arises when one cell divides or when two cells, like a sperm and an egg cell, fuse. Either event sets off a cell-replication program that is encoded in the DNA and executed by proteins.

Answers

Answer:

1.

air (atmosphere)

water (hydrosphere)

land (geosphere)

organisms (biosphere).

2.

The Earth's climate is created by the interaction of the atmosphere and the hydrosphere. Heat and moisture are stored in the atmosphere, whereas water vapor is stored in the hydrosphere. The interactions between the two aid in the distribution of heat and moisture around the globe, resulting in temperatures that are conducive to life.

3.

The biosphere and hydrosphere interact in the sense that the hydrosphere provides water for the biosphere to function, grow, and exist. Animals (biosphere) consume water (hydrosphere), and fish (biosphere) require water (hydrosphere) in order to survive and swim. The flood is another interaction between the biosphere and the hydrosphere.

Answers

Answer:

C is correct I think

Explanation:

A: Couldn't be because there is one less source that is consuming the algae, so algae wouldn't decrease

B: Number of pike wouldn't increase because it would be getting less food

C is correct because there would be less pike because there would be less food for them, so fishermen would catch less

D: Same explanation as B but for Dragonfly larvae

I’m thinking it C it seems like the best answer because without the larvae there would be less perch which they eat so with the decrease in perch there is less for pike to eat so more pike would die from hunger so there would be less pike for the fisherman.

Scientists found a layer of rock with several different fossils in it, as shown in the image. Based on the model, which of these fossils are the oldest and which are the newest? Explain your answer.

Answers

wouldn’t the bottom be the oldest?

Answer:

The oldest is section A, and the newest is section B.

Explanation:

First of all, the bottom most layer is almost always the oldest, because when rocks form, they don't go "hey lemme form under you", they form on top.

Second, bottom most layer is has the simplest fossils and the fossils are the same. You can see that as the higher section you go, the fossils are more complex and have more variety. Which is because of evolution.

Third, I don't know if this counts, but the bottom has the least color so I'm guessing that means that it has been decaying and whatever else you wanna call it than the other layers. Whereas the top is the most colorful, in my opinion.

Write an explanation of why a scientist may want to perform an experiment about the effect of the concentration of salt on the amount of electricity produced. (2-3 Sentences)

Answers

Because Electrical energy needs in Pakistan are expected to continue to rise. The use of petroleum as a source of energy still dominates, although oil reserves in Pakistan are increasingly being depleted. Therefore, there is a need to develop alternative source of sustainable energy, such as Microbial Fuel Cell (MFC). MFC shows another type of renewable energy by changing natural matter into power with the help of microbes. In the present study, varied salt concentrations of a salt bridge in novel MFC design were analyzed. Sewage sludge was utilized, which contains a lot of organic materials and is additionally one of the major sources of ecological contamination, as substrate MFC. Saccharomyces cerverciae sp. (44 g) was used as a biocatalyst. Methylene blue (10 ml) was used as a mediator and potassium ferricyanide (100 ml) was used as an oxidizing agent for the conversion of sewage sludge into voltage generation using lab-scale double chamber MFC. Varied salt concentrations (1M, 3M and 5M of KCl and NaCl) of salt concentrations of salt bridge in a novel MFC design were analyzed. The maximum generated voltage, current, power, power density and current density with 1M KCl were 0.451 V, 0.0451, 0.0175561 mW, 0.000226001 mW/m2, 10.5166661 μA/m2 respectively. The MFC was run for a period of 1 day and readings were noted at regular intervals. The results obtained were helpful in designing an optimized MFC.

A scientist may want to perform such an experiment probably because they want to find out if there's another type of food or drink or spice that could create energy.
