Answer:
S phase
Explanation:
S phase is the second phase of interphase (longest phase where cell grows and replicates it's DNA and does it function. It is broken up into smaller sub phases). S phase is the synthesis phase. During this phase chromosomes are replicated ( The DNA is copied).

Answer:
Yes,just yes no explanationExplain how this mutation will result in competition within the population that is linked to the idea of survival of the fittest.
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 theoryDarwin 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.

Why is the percentage of food eaten a good
number to use? Explain.
I
Intro
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.

In an energy pyramid, up to 10% of energy is transferred between trophic levels. Suppose the producer level has 50,000 J. Approximately how much energy is available to the next level, the primary consumer, in this energy pyramid?
Answer: 5,000
Explanation:So it is the 10% law, this is an example 10,000 for the first animal, 1,000 for the second and 100 for the third. So for 50,000 it would be 5,000 for the next

ESTOS ALIMENTOS DULCES AZUCARADOS NO SÓLO SON MALOS PARA LA SALUD,SINOQUE YANDIEN PUEDEN SER E________.AMENUDO SE DISFRASAN CON NOMBRES QUE PUEDEN SER S________ ,
La respuesta correcta para esta pregunta abierta es la siguiente.
Desafortunadamente, no anexaste opciones o incisos para responder la pregunta. Sin embargo, podemos comentar lo siguiente.
ESTOS ALIMENTOS DULCES AZUCARADOS NO SÓLO SON MALOS PARA LA SALUD, SINO QUE TAMBIEN PUEDEN SER ENGAÑOSOS. A MENUDO SE DISFRAZAN CON NOMBRES QUE PUEDEN SER SABROSOS.
Es muy importante que seas cuidadoso con los alimentos que consumes como parte de tu alimentación. Muchas empresas, a través de sus marcas, comparten publicidad engañosa para atraer más clientes bajo la promesa de alimentos sabrosos y nutritivos. Y la verdad es que no. Te están engañando.
No hay nada como basar tu dieta diaria en frutas, verduras y un equilibrio entre proteínas, carbohidratos, azúcares naturales y grasas.
Si es necesario, consulta a tu médico o a un nutriólogo para que te expliquen qué tan malo pueden ser los alimentos con muchos químicos.
¿Son sabrosos? Sí, pero también están llenos de sal, grasas, azúcares en excesos que le hacen mucho daño a tu salud.
En México ya existe una ley que obliga a todos los productos colocar unas etiquetas de color negro con blanco en todos los productos con la leyenda: "exceso de sodio," "exceso en grasas," exceso en azúcar."
Esto, con el propósito de que la gente se entere antes de comprarlos.
An oak tree falls in a forest. It kills some ants and stops grass from growing
below it. What type of disturbance is this?
O A. Secondary
O B. Primary
O C. Cyclical
O D. Small
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.

how might a country run out of water
Answer
Along with decreasing rainfall comes rising temperatures. By 2050 the U.S. could be as much as 5.7°F warmer, and extreme weather events, such as heatwaves and drought, could be more intense and occur more frequently. As temperatures warm, evaporation increases, further decreasing water in lakes, reservoirs, and rivers.

1) have a common ancestor
2) all grew at different rates
3) live for a long time
4) evolved slowly

Without knowing the genetic differences of the birds, how can we know that cardinals and finches are likely more closely related to each other than cardinals and finches are to woodpeckers? Cardinals and finches live in more similar habitats. There is no difference in their relatedness; because they are all birds, they all evolved at the same time from a common ancestor. Cardinals and finches have more morphological similarities. Fossil records show that cardinals have been around longer than woodpeckers and sparrows.
Answer:
The correct answer is - Cardinals and finches have more morphological similarities.
Explanation:
To find out the relatedness of the different species or organisms one can use genetic mapping to find precise relatedness, however, if one can not find the genetic differences of the organism one can use the morphological similarities and differences to find out how closely they are related.
Homologous structures and analogous structures are two major morphological characters to find how closely related cardinals and finches are than cardinals and finches are to woodpeckers.
