Answer:
Wilson has created the theory of the biogeographic nature of the island, which predicts that the number of species on the island depends on the balance between colonization, the evolution of the novel island species, and extinction.
Explanation:
A new DNA sequence containing 596 species of terrestrial birds from 41 island chains (archipelagos) around the world has been assembled by the researchers. The data combined sample data from their own field visits, research, and field samples from GeneBank colleagues. This information was utilized to build and employ a dynamic model that predicted international relationships that regulate biodiversity variation in their novel analysis approaches. In that, they confirmed two main components of MacArthur and Wilson's initial biogeography theory on the island.
The understanding of biodiversity on the island is important to conservation but also has implications beyond that – when imposing barriers to species dispersal it could enable us to assess better the effects of human activities, and it can contribute to a wider understanding of biodiversity around the globe.
The Cell Theory also states that all living cells have chloroplasts and a cell

Importance of photosynthesis to humans
Answer:
Green plants and trees use photosynthesis to make food from sunlight, carbon dioxide and water in the atmosphere: It is their primary source of energy. The importance of photosynthesis in our life is the oxygen it produces. Without photosynthesis there would be little to no oxygen on the planet.
Bonus: we eat plants

15. What must occur in order for genetic material to be passed to cells during cell division?
A DNA replication
B RNA synthesis
C osmosis
D diffusion
Answer:
A
Explanation:
the process involves replication of cell's chromosomes, segregation of the copied DNA and splitting of parent cell's cytoplasm
In order for genetic material to be passed to cells during cell division, DNA replication should take place, as in Option A, and the passing of genetic contents varies between mitosis and meiosis.
What is the significance of DNA replication in cells?DNA replication is the process by which the genetic contents of a cell, the DNA, are copied which is a crucial process that occurs in all living organisms and is necessary for the maintenance of their genetic information and the transmission of this information to the next generation, it is essential for cell division and growth, as well as for the repair of damaged DNA and plays a central role in animals and plants, as new life can form and cell division takes place due to this process.
Hence, in order for genetic material to be passed to cells during cell division, DNA replication should take place, as in Option A, and the passing of genetic contents varies between mitosis and meiosis.

4. Predict what a fossil that illustrates the
evolution of a bird from a reptile might look
like.
Answer:
The discovery that birds evolved from small carnivorous dinosaurs of the Late Jurassic was made possible by recently discovered fossils from China, South America, and other countries, as well as by looking at old museum specimens from new perspectives and with new methods. The hunt for the ancestors of living birds began with a specimen of Archaeopteryx, the first known bird, discovered in the early 1860s. Like birds, it had feathers along its arms and tail, but unlike living birds, it also had teeth and a long bony tail. Furthermore, many of the bones in Archaeopteryx's hands, shoulder girdles, pelvis, and feet were distinct, not fused and reduced as they are in living birds. Based on these characteristics, Archaeopteryx was recognized as an intermediate between birds and reptiles; but which reptiles

Natural selection will only lead to evolution if it allows for an organism to ________.
a. possess advantageous traits.
b. compete for resources.
c. produce offspring.
d. all of the above.
Answer:
b
Explanation:
Natural selection will only lead to evolution if it allows for an organism to process traits, compete for resources and produce offspring. The correct option is d.
What is natural selection?Natural selection is indeed an evolutionary mechanism. Lifeforms which are better adapted to their surroundings are much more likely to flourish and pass on the genetic traits that helped them thrive. Species change and diverge as a result of this process.
Natural selection, Darwin proposed, is a framework for evolution in which genetic variants that help support life, reproduce and survive as well as become more prevalent in a population over time.
Natural selection will occur if three conditions are met, according to Darwin's theory. These conditions, which are outlined as,
Represent a struggle for survival.Exhibit variation.Undergo inheritance.These are the conditions that are said to be both necessary and sufficient for natural selection.
Natural selection will only result in evolution if an organism is able to process traits, compete for resources, and produce offspring.
Thus, the correct option is d.

a. The continental plate goes under the oceanic plate (subducts) because the continental plate is
thinner than the oceanic plate.
b. The continental plate subducts under the oceanic plate because the continental plate is thinner
than the oceanic plate.
c. The oceanic plate subducts under the continental plate because the oceanic plate is lighter than the continental plate.
d. None of these
e. The oceanic plate subducts under the continental plate because though the oceanic plate is
thinner than the continental plate, it is more dense.

Explanation: When an oceanic plate converges with a continental plate, the oceanic crust will always subduct under the continental crust; this is because oceanic crust is naturally denser.
Why do organisms die if they do not have enough water?
Answer:
Organisms need water for the following activities: (1) All cellular processes occur due to water. (2) Transportation of substances in our body takes place by dissolving in water. (3) Terrestrial animals require fresh water for transportation of minerals and for getting rid of waste from their body.
Explanation:
Without water they cant do any of this.
Answer:
Cells will lose water and the chemical reactions take place in water. Without enough water, this can't happen.Explanation:

The change that is an environmental effect of building dams is increased water temperature upstream, which is in Option C, and humans can increase the rate of endangered or extinct species by reducing environmental impacts, which is in Option A.
What is Human activities on species?Human activities are the primary cause of species endangerment and extinction, so humans must take actions to reduce environmental impacts in order to increase the rate of endangered or extinct species, and by reducing hunting and poaching and restoring degraded ecosystems can help protect endangered species, and reducing carbon emissions and promoting sustainable development can help mitigate the effects of climate change.
Hence, the effect of building dams is increased water temperature upstream, which is Option C, and humans can increase the rate of endangered or extinct species by reducing environmental impacts, which is Option A.

Draw the structures of deoxyribose, guanine, and phosphate and rate their relative solubilities in water (most soluble to least soluble). How are these solubilities consistent with the three-dimensional structure of double-stranded DNA?
Answer:
The solubilities in water of the three molecules from most to least soluble is in the following order: phosphate > deoxyribose > guanine.
Explanation:
The phosphate group is the most water-soluble due to it being very much negatively charged .
The deoxyribose which has several hydroxyl groups, is the next most water-soluble molecule.
The guanine molecule is hydrophobic, therefore, it is the least soluble in water.
A DNA molecule is composed of the three molecules: deoxyribose sugar, a phosphate group and a nitrogenous base which could either be a purine or a pyrimidine.
The three dimensional structure of DNA is such that the the phosphate groups and deodyribose sugars form the backbone of the structure on the outside of the DNA double helix where they are exposed to the aqueous environment of the nucleus. On the other hand, the hydrophobic nitrogeneous bases are located in the interior of the double helix where they are excluded from excludedthe aqueous environment of the nuclues. This structural arrangement is in accordance with the solubility of the molecules where the water-soluble phosphates and sugars are exposed to water while the water-insoluble bases are away from water.
