Thousands of years ago, the jaws and teeth of jaguars were more varied in size than they are today. During a period of climate change about 11,000 years ago, jaguars faced a
shortage of food. There were fewer mammals to eat, so the jaguars had to eat shelled reptiles. The jaguars with the largest jaws and teeth could most easily eat the shelled reptiles.
Which of the following statements best explains why large jaws and teeth are common characteristics in jaguars today?
O A. Jaguars with the smallest jaws and teeth died out completely.
B. Jaguars with the smallest jaws and teeth were not ever able to mate.
O C. Jaguars with the largest jaws and teeth survived and reproduced more successfully than other jaguars.
D. Jaguars with the largest jaws and teeth strengthened them by using them more frequently than other jaguars.

Answer:

1. 36500 kcals

2. Producers

Explanation:

As organisms in one trophic level feeds on another organism in another trophic level, one must bear in mind that only 10% of available energy at each trophic level is transferred.

According to this question, the secondary consumer trophic level has 365 kcals of energy. Since there are primary consumer and producer trophic levels before this, it means that 100 times of energy was previously available at the producer level. Hence, 365 kcal × 100 = 36500 kcal of energy is available at producer level.

2. The producer level has the most available energy (kcal) among the trophic levels because they get it directly from the sun and are the first participants of the energy transfer.

Pigments, are the light-absorbing molecule that plants use to absorb energy, chlorophyll is the light absorbing pigment, hence option B is correct.

Plants get their green color from a pigment called chlorophyll, which also aids in photosynthesis, which is how plants make their own food.

In a plant, chlorophyll's function is to absorb light, often sunlight. Two types of energy storing molecules receive the light energy that is absorbed.

The plant uses its stored energy to turn water and carbon dioxide from the air into glucose, a form of sugar, through photosynthesis.

Therefore, chlorophyll is a pigment, considered as a light absorbing molecule that plants use to absorb energy, hence option B is correct.

If the amount of methane increases in the atmosphere, it leads more energy in the Earth and more energy will be taken by the surface of the planet.

Explanation:

Methane is pretty much like carbon dioxide and it does stop some energy from leaving the system but causes it to make the climate way more hotter than it should be. With lots of methane in the world, it can result into changes like mood swings and nausea in humans.

According to the condition if landfill waste increases, the amount of

Methane in the atmosphere will increase then it will lead to more energy to the Earth and more energy will be taken by the surface of the planet.

The aerobic process of composting does not have methane because methane-producing microbes are inactive in the existence of oxygen.
Composting is one way to decrease methane emissions from organic waste nowadays stockpiled or sent to landfills.

Thus, it will lead to more energy to the Earth and more energy will be taken by the surface of the planet.

Explanation:

Gregor Mendel (1822 - 1884) who is referred to as the FATHER OF GENETICS was an Austrian monk that contributed immensely to the principle of inheritance. He worked and conducted several experiments with the pea plant (Pisium sativum).

Mendel inheritance explains how traits are passed down from parents to offsprings. Mendel proposed three laws that governs inheritance namely: law of dominance, law of segregation and law of independent assortment of genes. The law of dominance states that one allele of a gene will always mask the phenotypic expression of another allele of the same gene in a heterozygous state.

The masking allele is called DOMINANT ALLELE while the allele being masked is called RECESSIVE ALLELE.

Answer:

A. The energy released from ATP based on the model is from the hydrolysis of the terminal phosphate group in ATP.

B. ATP in cells serves as a source of energy for cellular work/activity.

Explanation:

A. The energy released from ATP based on the model is from the hydrolysis of the terminal phosphate group in ATP. This hydrolysis of the terminal phosphate group of ATP proceeds with the release of a large amount of energy. This energy is called standard free energy of hydrolysis of ATP and is relatively large under standard conditions; about -30.5 kJ/mol.

The removal of the terminal phosphate group is able to release this amount of energy because it relieves some of the electrostatic repulsion of the negative charges the three phosphate groups in ATP. Also resonance stabilization of the released phosphate group contributes to the energy released.

B. ATP in cells serves as a source of energy for cellular work/activity. The hydrolysis of the high-energy phosphate bonds as well as the coupling of the energy released to energy-requiring reactions in the cell is the mechanism used by the cells to utilize the energy released by ATP. This couplingis usually in the form of transfer of a phosphoryl group, pyrophosphoryl group, or adenylyl group from ATP to a substrate or enzyme which then uses the energy released to transform substrates to products.

Answer:

Explanation:

So basically you will need to

Answer;

Earthquakes, landslides, volcanic eruptions and natural bush fires all affect the many different ecosystems on our planet. Initially, these disasters negatively affect the biodiversity of wetlands, forests and coastal systems by causing the spread of invasive species, mass species mortality and loss of habitat. In the short term, select ecosystem degradation reduces the ability of forests to sequester carbon, which exacerbates climate change. Over time though, many types of natural disasters play an integral role in rejuvenating the very ecosystem that they once destroyed.

TSUNAMI

Once referred to as tidal waves, a tsunami represents an extremely high wave of water that moves from out at sea towards land. Because of the enormous volume of water and energy that travels inland, extended areas along the coast are immediately devastated as these natural disasters strike the coastal ecosystems. Underwater landslides, earthquakes and volcanic eruptions can all cause tsunamis, by displacing gigantic waves that are sustained by gravity as they travel towards land at over 800 kilometers per hour. Tsunamis are also caused as the ocean floor suddenly deforms due to tectonic earthquake activity and vertically displaces the immense volume of water lying above it. While out at sea, tsunamis have a small wave height, but extended wavelength of up to 200 kilometers. The height of these waves rises dramatically, though, as the tsunami reaches land and the resulting damage to coastal ecosystems can be cataclysmic. As coral reefs, mangrove forests and wetlands are all dependant upon each for nutrient supplies, the destruction of one will ultimately affect the overall coastal ecosystem. The destruction of coral reef fish populations leads to the elimination of other species that depended on them as a food source, while on land, the soil that was exposed to salt sedimentation, becomes infertile, resulting in the loss of biodiversity in the form of coastal forests and the animal life that they supported.

VOLCANIC ERUPTION

The eruption of volcanoes and subsequent lava flow has an immediate negative effect on surrounding ecosystems, but through the process of primary succession, the forest habitat begins the process of re-colonization almost immediately. Many plants in the form of seeds and spores and animal species, particularly insect life such as crickets and spiders, arrive from adjacent areas to take up residence. These life forms are specifically adapted to survive in the severe conditions following a larva flow and spearhead the succession process. The progeny of these pioneer species changes the original sterile conditions to the point where a new and normally more diverse forest ecosystem has developed within a 150 year period.

Volcanoes would most likely have the longest impact on the affected ecosystem.

An opening in the crust of a planet or moon known as a volcano allows molten rock, heated gases, and other things to erupt. As layers of rock and ash accumulate from numerous eruptions, volcanoes frequently take the form of a hill or mountain. There are three types of volcanoes: active, dormant, and extinct.

Here, volcanoes can form when an oceanic plate sinks beneath another oceanic plate or when an oceanic plate sinks beneath a continental plate. Subduction is the process that causes different kinds of volcanoes based on the environment: An island-arc volcano is produced by ocean-ocean subduction.

Hence, volcanoes would most likely have the longest impact on the affected ecosystem.
