Stephan’s mother is a mineralogist, and sometimes she brings home samples to study. Stephan observesand compares these minerals. He knows minerals form in several ways. He is especially interested in the minerals that form from volcanic activity and the kinds of crystals they form. What determines crystal size in minerals formed by lava or magma?
A. the kind of mineral that formed
B. the amount of material available
C. the rate at which the minerals cooled
D. the materials in the lava or magma

Answers

Answer 1
D!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Answer 2

The rate at which the minerals cooled determines the crystal size in minerals formed by lava or magma. The correct option is C.

What determines crystal size in minerals?

The solution is extremely saturated with some minerals, crystals form as magma cools. The crystals are quite tiny because they did not have much time to form if the magma cooled quickly. The crystals have ample time to form and become huge if the magma cools gradually.

The rate at which the minerals cooled Crystal size in minerals formed by lava or magma is primarily determined by the rate at which the minerals cooled.

When lava or magma cools slowly, it allows crystals to grow larger. Conversely, when it cools rapidly, crystals have less time to grow and thus remain smaller.

Therefore, the correct option is C.

The graph below shows how the numbers of two different organisms in a forest changed over time. The changes in population sizes can be used to make inferences about the relationship between wolves and rabbits in this forest.




Based on the information in the graph, what is the most likely relationship between these organisms?
A.Wolves are predators of rabbits.
B.Rabbits and wolves rely on the same food source.
C.Wolves and rabbits have a mutualistic relationship.
D.The relationship between wolves and rabbits is commensalism.

Answers

I’m pretty sure it’s D.

Based on the information in the graph, the most likely relationship between the organisms is that wolves are predators of rabbits. So, the correct option is A.

According to the graph, the rabbit population decreases as the wolf population increases and vice versa. This trend points to a predator-prey interaction in which an increase in predator population causes a decline in prey population, and vice versa. Changes in one population have a direct effect on another, as seen by the variation in population size of wolves and hares.

So, the correct option is A.

Answer: Solar Flares

Explanation: The Sun's magnetic field goes through a cycle, called the solar cycle or known as solar flares. Every 11 years or so, the Sun's magnetic field completely flips. This means that the Sun's north and south poles switch places. Then it takes about another 11 years for the Sun's north and south poles to flip back again.

Photosynthesis is to oxygen as:

A. Oxygen is to carbon dioxide
B. Cellular respiration is to carbon dioxide
C. Cellular respiration is to oxygen
D. Cellular respiration is to enzymes

Answers

Answer: It is C but if it was multiple choice it would be both B and C.

Explanation: Allow me to explain my reasoning. During the process of glycolysis in cellular respiration, glucose is oxidized to carbon dioxide and water. Energy released during the reaction is captured by the energy-carrying molecule ATP (adenosine triphosphate). And allow me to explain the answer C. Cellular respiration can occur both aerobically (using oxygen), or anaerobically (without oxygen). During aerobic cellular respiration, glucose reacts with oxygen, forming ATP that can be used by the cell. Carbon dioxide and water are created as byproducts. In cellular respiration, glucose and oxygen react to form ATP. Therefore, it can be both B and C if it was multiple choice. Thank you for your time.

Photosynthesis is to oxygen as Cellular respiration is to carbon dioxide. Thus option B is correct.

what is photosynthesis ?

The process in which sunlight energy is used by  plants, algae and certain bacteria convert them into chemical energy and starch called as photosynthesis.

Photosynthesis occur in chloroplast  which has its own DNA, genes and hence can synthesize their own proteins, photosynthestic Pigments responsible for trapping sunlight present in chlorophyll pigment of chloroplast, like chlorophyll a, b and c.

Bacteria also have chlorophyll known as bacteriochlorophyll can absorb infrared rays, other pigments are Carotenoids which are yellow, orange or red-coloured pigments that absorb bluish-green light., Xanthophyll, Phycobilins.

plastids are found in the cytoplasm of eukaryotic photosynthetic organisms. They contain pigments and store nutrients. Plastids are of three types such as Leucoplast, Chromoplasts, Chloroplasts

Antennae is made up of 100 to 5000 pigment molecules that capture light energy from the sun in the form of photons, Reaction Centers where photosynthesis occur.

Answer the following questions in complete sentences in the space provided:

1. Why does cell division take place in single-celled organisms?

2. What occurs in a cell when it is not undergoing cell division?

3. How do chromosomes change before cell division?

4. What is mitosis?

5. Why doesn’t mitosis occur in prokaryotes?

6. What would happen if DNA did not duplicate during interphase?

7. What is cytokinesis and when does it happen?

8. During what phase of mitosis do the chromosomes line up?

9. When do the chromosomes condense and become visible under a microscope? 10. What happens to the chromosomes during anaphase?

11. Sometimes a cell inaccurately duplicated its DNA, and the resulting cells are not identical. What effects might such a change have on the organism?

Answers

Answer:

1.All multicellular organisms use cell division for growth and the maintenance and repair of cells and tissues. Cell division is tightly regulated because the occasional failure of regulation can have life-threatening consequences. Single-celled organisms use cell division as their method of reproduction.

2.What happens to cells that "decide" not to divide? If the decision is to not divide, the cell goes into a quiescent, or nondividing state, called G0 (G zero).

3.Prophase is the first phase of mitosis. During this phase, the chromosomes inside the cell's nucleus condense and form tight structures. In fact, the chromosomes become so dense that they appear as curvy, dark lines when viewed under a microscope (Figure 1).

4.Mitosis is a process where a single cell divides into two identical daughter cells (cell division).

5.In bacterial cells, the genome consists of a single, circular DNA chromosome; therefore, the process of cell division is simplified. Mitosis is unnecessary because there is no nucleus or multiple chromosomes. This type of cell division is called binary fission.

6.If a cell has not properly copied its chromosomes or there is damage to the DNA, the CDK will not activate the S phase cyclin and the cell will not progress to the G2 phase. The cell will remain in S phase until the chromosomes are properly copied, or the cell will undergo programmed cell death.

7.Cytokinesisis the part of the cell division process during which the cytoplasm of a single eukaryotic cell divides into two daughter cells. Cytoplasmic division begins during or after the late stages of nuclear division in mitosis and meiosis.

8.Metaphase. Chromosomes line up at the metaphase plate, under tension from the mitotic spindle. The two sister chromatids of each chromosome are captured by microtubules from opposite spindle poles. In metaphase, the spindle has captured all the chromosomes and lined them up at the middle of the cell, ready to divide.

9.During prophase, the complex of DNA and proteins contained in the nucleus, known as chromatin, condenses. The chromatin coils and becomes increasingly compact, resulting in the formation of visible chromosomes.

11.When Replication Errors Become Mutations. Incorrectly paired nucleotides that still remain following mismatch repair become permanent mutations after the next cell division. This is because once such mistakes are established, the cell no longer recognizes them as errors.
