Clownfish, sea anemone, coral, sea urchins, sponges, and parrot fish are just a few examples of the large variety of organisms that can be found in a coral reef. The coral reef and its inhabitants are suffering due to several factors such as pollution, coastal development, sedimentation and destructive fishing practices. What would be the most likely result if some of the species in the coral reef are destroyed? Other organisms would move into the coral reef area The coral reef would be allowed to flourish without so many fish and plants living in and around it. The coral reef would begin to deteriorate without the variety of fish and plants necessary to maintain balance. The waters surrounding the coral reef will become cool with the decreasing number of organisms living there
Answer:
The coral reef would begin to deteriorate without the variety of fish and plants necessary to maintain balance

Which of the following is a result of geological changes that impact the dynamics of an ecosystem?
Humans introducing an invasive species, resulting in loss of biodiversity
Speciation, causing an increase or decrease in competition among different species
Habitat fragmentation, due to the construction of new housing complexes
Pollution from factories, causing increasing atmospheric carbon dioxide
Answer: B speciation causing an increase or decrease in competition among different species.
The other choices are the HIPPCO or the human impacts that cause extinction not geographical changes
The geological changes that impact the dynamics of an ecosystem Speciation, drive an increase or decrease in contest among different species.
What is the process of speciation?Speciation is the process by which new species form. It happens when groups in a species become reproductive remote and branch.
In allopatric speciation, sets from an established population grow into various species due to years of geographical separation.
Thus, option "B" is correct, Speciation is how a new type of plant or animal species is created.

Binomial nomenclature refers to the method of naming species
with two names, consisting of the____
name and___
name.
Answer:
Genus and species
Explanation:
Binomial nomenclature refers to the method of naming species with two names, consisting of the genus name and species name.
What is Binomial nomenclature?
A binomial system of naming a species is known as binomial nomenclature. A binomial name has two components. They are the particular name and the generic name (genus name) (or specific epithet, in botanical nomenclature).
It frequently takes a Latinized form. Similar terms include binary nomenclature, binominal nomenclature, and two-term naming systems.
Binomial nomenclature, which assigns a single, distinctive name identifier for a particular species across several languages, is crucial for integrating the naming system across life sciences.
Therefore, Binomial nomenclature refers to the method of naming species with two names, consisting of the genus name and species name.

Water, while beaker b has 50 ml of water. B. State the beaker which is going to require more time to reach room temperature, explain your answer
Answer:
The beaker has more water.
Explanation:
The beaker which has more water takes more time to reach the room temperature because it has more surface area than other one. If a body has less surface area then it will lose heat energy quickly and to reach its room temperature as compared to the body that has more surface area. Heat transfer depends on the materials in which it is placed and the surrounding environment. In some materials conduction of heat occurs quickly as compared to other materials.

Clasisifcar los huesos del esqueleto apendicular y axial en : largos, cortos, planos, irregulares, sesamoideos. ayudaaa por favor!!
Answer: Se clasifican de acuerdo a la forma y tamaño.
Explanation:
El esqueleto posee distintas funciones como el soporte del cuerpo en sí y la protección de órganos vitales. Para lograr esto, existen distintos tipo de huesos con distintas formas, de acuerdo a su ubicación y función.
Los huesos del esqueleto humano se dividen en dos grandes grupos:
Esqueleto apendicular: Huesos que forman los miembros superiores e inferiores, además de la cintura escapular y la pelviana. El esqueleto axial: Huesos del eje largo del cuerpo en la cabeza, columna y caja torácica.Tanto en el esqueleto apendicular como en el axial, existen cinco tipos de huesos: largos, cortos, planos, irregulares, sesamoideos.
Largos: Se clasifican así por ser mas largos que anchos y su función es la de soportar el peso del cuerpo y producir movimiento. Se ubican principalmente en el esqueleto apendicular como por ejemplo, huesos del miembro inferior como el fémur, tibia y peroné de las piernas. Además de los huesos en los miembros superiores como radio, húmero, cúbito en los brazos; y falanges metacarpianos en las manos.Cortos: Se clasifican así por tener aproximadamente la misma longitud que ancho, y su función es proporcionar estabilidad y movimiento. Estos huesos se ubican en articulaciones del tobillo y muñeca. y algunos ejemplos son los huesos tarsianos en tobillos (navicular, cuboides, astrálago, calcáneo, cuneifrome lateral, intermedio y medial); y los huesos carpianos de la muñeca (piramidal, pisiforme, trapezoide, trapecio, escafoides, hueso ganchoso, hueso semilunar, hueso grande)Planos: Son huesos de forma plana y su tamaño de área grande sirve para la unión de distintos músculos. Su función principal es la de la protección de órganos internos. Entonces, se encuentran en la caja torácica (donde se encuentran por ejemplo las costillas y esternón), y en la pelvis (donde se encuentra el ilion, isquion y pubis). También forman parte de la estructura ósea de la cabeza, donde se hallan los huesos occipital, frontal, parietal, lagrimal, nasal y vómer.Irregulares: Su forma y estructura es variable además de que pueden tener forma compleja. Su función es la de proteger órganos internos, por ejemplo a la médula espinal que es protegida por las vértebras y huesos irregulares de la columna vertebral .Sesamoideos: Huesos redondos en tendones donde los protegen del deterioro, particularmente en los tendones de las manos, pies y rodillas, como por ejemplo la rótula.There are several factors that lead to genetic variation in organisms. Which of the following is NOT one of those factors?
Answer:
The correct answer is - A. Producing offspring that are genetically identical to the parents
Explanation:
Genetic variation is the difference between the population or individual on a genetic level. If there is a change in the DNA of individuals or among the population, it is genetic variation in these organisms.
There are several factors that result in genetic variation such as random mating, random fertilization, mutation, crossing over during meiosis, and many more. Producing genetically identical offspring to the parents is not a factor as there is no variation is taken place on the genetic level.

Explain why the pulse rate taken at the wrist could actually be lower than if you listened to the heart rate with a stethoscope right over the heart.
Answer:
under
Explanation:
To accurately test for a slow heart rate, a person must measure their resting heart rate. To achieve this, they must avoid checking the pulse shortly after exercising or waking up.
To check the pulseTrusted Source, a person should sit in a comfortable and relaxed position and feel for the pulse at the wrist. If unable to locate the pulse at the wrist, they should try feeling for the pulse on the side of their neck.
To work out their heart rate, the person counts heartbeats for 10 seconds, then multiplies the number by six. For a more accurate pulse, the person can count the number of beats for a full minute. This figure is the resting pulse.
If the number is lower than 60, a person has bradycardia.

Fossils in _______ layers of rock are generally estimated to be _______ than fossils found in the deeper layers. (3 points)
older, younger
newer, younger
older, older
newer, older
Answer:
Answer number 2
Explanation:
So in Geology, Precipitation of rock layers took place over the last hundreds of millions of years...During that process many living organisms have died and are precipitated with the rock layers... Let me explain with an example.
Dinasours went extinct Million years ago while the Dodo bird went extinct a couple of hundred years ago
Would you expect to find Dinasour fossils in newer rock layers or the dodo? lets's say 200m deep? Dodo for sure, Dinasour fossils are waay too old to be found at such shallow deeps that's why fossils in newer layer of rocks are absolutely younger than fossils found at deeper layers
