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.

The Explanation for the Question:

Deep ocean currents, a.k.a Thermohaline Circulation, are caused by the sinking and the transportation of large masses of cold water, which is guided by density inclines due to contrasts in temperature and salinity. Deep currents are also caused by the earth's rotaion.

Answer:

Water covers about 71% of the earth's surface. 2.5% of the earth's fresh water is unavailable: locked up in glaciers, polar ice caps, atmosphere, and soil; highly polluted; or lies too far under the earth's surface

Explanation:

Answer:

We need to leave water for animals i guess

Explanation:

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:

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.

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.

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:

Biotic:The bugs and the trees

Explanation:

The bugs wouldn’t be eaten by the frogs because frogs rely on water and the trees would survive from rain.

Answer:

3.) The giraffe has adapted by it's neck length increasing to reach the branches

4.) Biotic factors

Explanation:

QUESTION 3: Due to the leaves growing towards the top of tree rather than around, the giraffes neck length impacts the access to the leaves, so they have adapted by increasing their neck length.

QUESTION 4: Giraffes and trees are both living things, therefore they are biotic factors.

Answer:

The soil is already present at the start of secondary succession.

Explanation:

Secondary succession is usually faster than primary succession because soil and nutrients are already present due to 'normalization' by previous pioneer species.
