Answer:

Survival of the fittest, term made famous in the fifth edition (published in 1869) of On the Origin of Species by British naturalist Charles Darwin, which suggested that organisms best adjusted to their environment are the most successful in surviving and reproducing. Darwin borrowed the term from English sociologist and philosopher Herbert Spencer, who first used it in his 1864 book Principles of Biology. (Spencer came up with the phrase only after reading Darwin’s work.)

Herbert Spencer's Principles of Biology (1864) first introduced the expression “survival of the fittest.”

Darwin did not consider the process of evolution as the survival of the fittest; he regarded it as survival of the fitter, because the “struggle for existence” (a term he took from English economist and demographer Thomas Malthus) is relative and thus not absolute. Instead, the winners with respect to species within ecosystems could become losers with a change of circumstances. For example, fossil evidence supports the notion that the mammoth (Mammuthus) was more fit during the most recent ice age (which ended roughly 11,700 years ago), but it became less fit as humans hunted it and the world’s climate warmed; fossil evidence suggests that the mammoth succumbed to extinction a few thousand years later.

Darwin’s theory of evolution by natural selection entailed three crucial elements: variation, reproduction, and heritability. Variations in the physical features of organisms that tend to benefit an individual (or a species) in the struggle for existence are preserved and passed on (or selected), because the individuals (or species) that have them tend to survive. The success or failure of a given variation is not known when it emerges; it is known only retrospectively, after organisms that possess it either grow and mature and pass it to their own offspring or fail to mature and reproduce.

Importantly, Darwin was influenced by the thinking of English physicist and mathematician Isaac Newton, whose system emphasized experimentation, mathematics, and logic over subjective sense experience. During Darwin’s time, his evolutionary theory was an attempt to construct a similar system for the living world, a frontier not yet crossed in the biological sciences.

Some philosophers and scientists have suggested that the notion of survival of the fittest is an example of circular reasoning—that is, a tautology (a statement framed in such a way that it cannot be falsified without inconsistency). In tautologies, any true statements that follow are a matter of definition. Indeed, describing those that survive as the fittest is similar to stating that those that survive survive. British philosopher Karl Popper considered “survival of the fittest” self-evident at first; however, he changed his mind after realizing that Darwin posited variation axiomatically; that is, Darwin noted that all individuals did not start with the same set of characters (or traits). Therefore, the forces affecting survival did not weigh on individuals and species equally; there were always variations, some of which would prove favourable and confer fitness over others.

Answer: Light is necesarry for photosynthesis to occur

Explanation:

Based on the information given in the question, the investigation was most likely testing the hypothesis that light is necesarry for photosynthesis to occur.

Photosynthesis, simply means the process by which green plants transform light energy into chemical energy. It should be noted that during photosynthesis, light energy is captured which is then used in the convertion of carbon dioxide and water, into oxygen and energy which comes in form of sugar.

Answer: This investigation was most likely testing the hypothesis that SUNLIGHT is necessary for photosynthesis

Explanation:

Photosynthesis can be defined as the process by which plants (green plants) use inorganic compounds such as carbondioxide and water to manufacture their own food. This process is not only important to plants but also to animals which depends on plants for food. The main features of photosynthesis include:

--> it takes place in chlorophyll of plant cells

--> Raw materials needed for this process are inorganic compounds such as carbondioxide and water

--> Final products are organic compounds such as sugar and oxygen as by product.

--> Energy needed for this process is gotten from SUNLIGHT which is absorbed by the chlorophyll.

To show that sunlight is necessary for photosynthesis, an experiment is performed as stated in the question above. Only the part of the leaf that had NOT BEEN covered turned blue black because the exposed part has been actively photosynthesizing due to the presence of SUNLIGHT. While the covered part didn't undergo any photosynthesis as it tested negative for starch when placed in Lugol's iodine solution.

Answer:

Very necessary for its survival.

Explanation:

Movement of molecules is very important to maintain a healthy cell environment because some molecules are required by the cell for its growth and development. Some molecules moves inside the cell environment through a semi-permeable membrane such as glucose, oxygen, potassium etc while on the other hand, some molecules are removed from the cell which are waste materials such as carbondioxide etc. If these waste materials are not removed from the cell, it greatly damaged the cell.

Answer:

I. Divergent

II. Convergent

III. Transforming

Explanation:  

The crust is the outermost layer of the earth. It is divided into many plates that move over the mantle. Nowadays, there are six different bigger plates and twelve that are smaller. These plates are limited by three types of ridges or borders that differ in the movement they produce.

Boundaries types:

I. Divergent: New crust is created by the rising molten materials coming from the mantle. Two plates separate, and the stream of hot material creates a new seabed between them. It occurs an expansion of the sea bottom. As old plates get separated, the new and young crust instantaneously gets formed. The emerging mantle occupies the space left by the separation of the two plates. This process occurs along with an underwater mountain range, known as the mid-oceanic ridge or divergent ridge. An example of this is the ridge located in the middle of the Atlantic Ocean, extending from Greenlander to the southernmost point of South America.

II. Convergent. Collision area between two plates. Two oceanic plates might collide, or one oceanic plate with a continental one. In this last case, the oceanic crust sinks under the continental plate, and magma rises to the surface by crevices. The thicker and older plate subduces under the other plate. The Himalayas and Los Andes are examples of these collisions. Also, collisions create volcanic arches and continental arches.

III. Transforming. The plates slide laterally with each other, and they are usually called faults. It is associated, in general, with the oceanic ridge, although it might also occur in the continental plate. No rocky material is either destroyed or formed. When the plates move and produce a displacement of one transforming limits from side to side, earthquakes occur. The movement breaks the crust and originates pronounced fractures. The San Andrés fault is an example of this plate ridges.

The kinds of boundaries that plates form is the fact that seismic activity takes place at the three known types of plate boundaries called divergent, convergent, and transform.

One converging plates often shift or move below the other, in  an act known as subduction.

The new magma (molten rock) tend to increase and may erupt to create volcanoes.

Answer:

This is O D. Small type of disturbance.

Explanation:

Small-scale biological disturbance.

Answer:

O D. small

Explanation:

In ecology a disturbance is an event that causes a change in the environment. There are small-scale disturbances and high-magnitude disturbances. Small-scale disturbances are typically driven by biological processes -for example the fall of a tree- while high magnitude disturbances are typically driven by physical processes -for example, storms-. Small-scale disturbances as single-tree blowdowns are very important  to create and maintain diversity and heterogeneity in the forest.

It is a season in which fish reproduce.

Explanation:

Piracema is not name of the fish, its the name given to the period of the year when fish reproduce within the Paraguay River. The season of reproduction started from October till March, during this period the fish swim upstream to lay their eggs and reproduce. Thus the season is critical for the maintenance of fish populations in the waters of the rivers and lakes. Brazilian states prohibit fishing during this period in order to maintain fish population in the river.
