Scientists recently discovered that three different types of squid, a marine animal, previously thought to be three different species, were actually all members of one species. Their earlier ideas were based on using squid carcasses (dead bodies). The new, more accepted classification is most probably based on an analysis of
A. a greater number of squid carcasses
B. the feeding habits of the three different species
C. a number of newly found squid fossils
D. the DNA present in the cells of squid

After a forest fire, which type of organisms will begin secondary succession?
small shrubs
mature oaks
evergreens
wildflowers

Answers

After a fire, species start to recolonize an area, beginning the secondary succession process. The first species to colonize are usually fast growing herbaceous plants, such as conifers or ferns.

Small shrubs are the kind of organisms that start secondary succession after a forest fire. The correct option is A.

Thus, the term "secondary succession" describes the ecological recovery process that follows a disruption like a fire. Small shrubs have developed survival strategies that enable them to swiftly colonize damaged environments.

They have the capacity to emerge from subterranean structures once again or to create seeds that will take root in newly accessible sunshine and nutrients. Due to their quick growth and capacity to keep the soil stable, these shrubs facilitate the establishment and flourishing of other plant species.

Thus, the ideal selection is option A.

Explain how different types of cells help organisms live and grow?
Different types of cells have different jobs that are necessary to keep organisms alive.
Different types of cells are only found in specific types of organisms.
Cells are necessary in order for all organisms to grow big and hunt for their food source.
Cells provide support for all organisms to be able to move.

Answers

Answer:

Different types of cells have different jobs that are necessary to keep organisms alive. And cells also give the living animal more support. They also hold the genetic information of that organism in their nucules. This is with most cells but bacteria cells do not contain nucules.

What is a continental shelf?

The undersea boundary of a continent is known as a continental shelf. The seven major divisions of land on Earth are called continents. From a continent's shoreline to a point known as the shelf break, a continental shelf runs.

Due to its relative accessibility, the continental shelf is the area of the ocean floor that is most understood. The continental shelf is where the majority of commercial sea resource extraction occurs, including the extraction of hydrocarbons, non-metallic ore, and metallic ore.

Thus, the continental shelf is exposed during glacial periods but covered by ocean water during non-glacial periods.

Explain how this mutation will result in competition within the population that is linked to the idea of survival of the fittest.

Answers

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.”

Survival of the fittestQUICK FACTSKEY PEOPLEAlfred Russel WallaceHerbert SpencerRELATED TOPICSAdaptationNatural selectionDarwinian fitnessUse in evolutionary theory

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.
