Answer:

They do cause an increase in greenhouse gases.

Explanation:

Renewable resources are the resources that are available in abundance that do not have adverse effect to the nature. These resources are available in abundance and they are not subject to extension. They are also said to be known as clean energy. renewable energy is obtained by the renewable resources. The pollution is caused minimal and the energy is saved by the use of renewable resources.

Explanation:

Question has been asked before so I know the answer.

Answer:

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.

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.

Explicación:

El registro fósil es la evidencia de la evolución a la que se refieren los árboles evolutivos. La relación entre organismos se puede averiguar estudiando fósiles de organismos. Los árboles evolutivos también se denominan árbol filogenético y muestran las relaciones evolutivas entre varias especies basadas en similitudes y diferencias en sus características físicas o genéticas. Se consideran similares aquellos organismos que tienen las mismas características físicas o genéticas.

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:

death of test mice, growth of virulent pneumococci, indicating DNA was the agent of transformation

Explanation:

In an experiment conducted by three scientists namely: Oswald Avery, Colin MacLeod and Maclyn McCarty in 1944, it was proven that DNA is the substance that causes transformation in bacteria as opposed to proteins.

In this experiment, Avery and his colleagues combined a dead but virulent strain of Streptococcus pneumoniae & a living but avirulent strain of the same bacterium and inserted into a living rat. They found out that the test specimen (rat) died and observed the growth of the virulent pneumococci.

This suggests that the virulent strain of bacteria has transferred its virulent DNA via transformation into the avirulent strain to kill the rat. Hence, indicating DNA as the agent of transformation.

Answer:

The percentage of food gives an idea about the food availability for the species of organisms. If the food percentage is high the species is observed to be more successful; on the other hand if the percentage is low the species is found to shrink in numbers.
