The vast majority of all species who have ever lived on earth no longer exist. Far more organisms have become extinct than are currently alive. Why? A. Species are continually being replaced or changed into other species by evolution. This process is currently very rapid compared to how long life has existed on earth. B. Over the past two million years, human interference has continually and significantly decreased animal and plant biodiversity. C. Mass extinction events like meteor impacts and climate changes have destroyed most life on earth. D. The biodiversity of life on earth continually decreases as natural selection eliminates species that are less fit for survival.
Far more organisms are currently organisms Species are continually being replaced or changed into other species by evolution.
What is Evolution?More than 99 percent of all organisms that have ever lived on Earth are extinct. As new species evolve to fit ever changing ecological niches, older species fade away.
But the rate of extinction is far from constant. At least a handful of times in the last 500 million years, 75 to more than 90 percent of all species on Earth have disappeared in a geological blink of an eye in catastrophes we call mass extinctions.
Though mass extinctions are deadly events, they open up the planet for new forms of life to emerge. The most studied mass extinction, which marked the boundary between the Cretaceous and Paleogene periods about 66 million years ago, killed off the nonavian dinosaurs and made room for mammals and birds to rapidly diversify and evolve.
Therefore, Far more organisms are currently organisms Species are continually being replaced or changed into other species by evolution.

What are brown bears doing as a result of panting
Answer:
Maintaining body temperature by cooling down
Explanation:
Brown bears have adaptive strategies to lower down the body temperature during hot months. Under hot sunny day, their breath rate is increased with shallow breaths. This is called as panting. The shallow breaths allow the cooler air to circulate over the moist mouth surfaces and leads to lower down the body temperature.

Which of the following statements about energy producing technologies is true?
a.
Some currently used energy producing technologies have no disadvantages.
b.
Alternatives to nonrenewable energy sources can be as effective.
c.
Air pollution is common to all energy producing technologies.
d.
Alternatives to nonrenewable energy sources are typically more damaging to the environment.
Answer:
Option (b).
Explanation:
Energy producing technologies are important for the formation of energy from the different sources of energy. The energy requirement for the growing population is much faster than the previous population.
The energy must be extracted from the renewable source of energy. New energy producing technologies must be alternative to the non renewable sources of energy. They must be cost effective than the earlier source of energy.
Thus, the correct answer is option (b).

When Earth cools most energy transferred from earths surface to space is transferred by the process of radiation. The correct option is 4.
What is radiation?Radiation is energy that travels through space at the speed of light from a source. This energy is associated with an electric and magnetic field, and it has wave-like properties. Radiation is also known as "electromagnetic waves."
The flow of electromagnetic energy between the sun and the Earth's surface as influenced by clouds, aerosols, and gases in the Earth's atmosphere is known as atmospheric radiation.
Radiation from the warmed upper atmosphere, as well as some from the Earth's surface, is emitted into space.
The majority of the longwave radiation emitted warms the lower atmosphere, which in turn warms our planet's surface.
Thus, the correct option is 4.

Select the part of the ATP molecule that stores and releases energy.
A
B
C
D
Answer:
The correct answer is B.
Explanation:
ATP stands for adenosine triphosphate. ATP is considered as the energy currency of the cell because it provides lots of energy during metabolic processes. The energy in ATP is stored as a high energy terminal phosphate bond which means the energy will release when the terminal phosphate bond will break.
As the terminal phosphate bond breaks the energy is released which is used by the cell to perform some metabolic activity. After this reaction, the ATP converts into ADP. So the correct answer is B.
_____ bonds form and hold the DNA together.
A. hydrogen
B. peptide
C. polar

When encountering other vessels in darkness or reduced visibility, what does a visible white light indicate?
Final answer:
A visible white light on a vessel in darkness or reduced visibility usually signifies the presence of another craft and helps in determining its activity and positioning, contributing to safe navigation.
Explanation:
When encountering other vessels in darkness or reduced visibility, seeing a visible white light often indicates the presence of another craft. It is important for safety reasons to understand these visual signals to prevent collisions and navigate safely. In maritime navigation, a single white light suggests different situations depending on its behavior and positioning. For example, if the white light is seen in both the bow and stern, it suggests that you are seeing the port (left) or starboard (right) side of a power-driven vessel underway. However, if only one white light is visible and it is at a high elevation and not moving, this could indicate the presence of an anchored vessel.
Visibility at sea is crucial, especially when natural light is obscured. Maritime regulations stipulate specific lighting configurations for vessels to communicate their type, activity, and relative movement to other vessels. Ascribing to these regulations aids mariners in identifying the position and behavior of nearby vessels, thereby enhancing navigation safety. In fog or other circumstances of reduced visibility, the sound signals become equally important—different sounds signal different actions, such as a vessel under power making way, a vessel at anchor, or a vessel in distress.
Difference between apodictic and casuistic law
Apodictic laws are absolute, universal norms from timeless principles, while casuistic laws are applied to specific cases within a temporal context. The distinction lies between unchanging laws and context-sensitive applications of law.
The difference between apodictic and casuistic law reflects varying approaches to legal and natural order. Apodictic laws are absolute, universal norms, akin to laws of nature as discussed by Augustine, where there is a recognition of eternal laws, which are unchanging and absolute, and temporal laws, often referred to as human laws. Casuistic laws, in contrast, are more akin to the Roman legal tradition, where there is an acknowledgment of circumstances, and laws are applied to specific cases, factoring in particular conditions and contexts.
Apodictic laws are characterized by a lack of temporal reference, indicating that they are perceived as constant and not dependent on the changing states of affairs or individual instances. Conversely, casuistic laws relate to ontologic knowledge, where every judgment or application of law is tied to particular moments in time and specific details of cases, much like the Roman lawyers' application of Stoic principles to concrete legal circumstances.
Fundamentally, the distinction underscores the difference between universally binding principles that transcend time and space and the context-sensitive judgments that adapt to the nuances of individual scenarios. In legal systems, this difference often manifests in the balance between written statutes (more apodictic) and judicial decisions or case law (often more casuistic).

Continuous bubbling in the suction control chamber of a closed chest drainage system indicates an air leak in a client who is 1 day post thoracotomy. The nurse should assess the client's condition, check the chest tube and connections, and notify the healthcare provider to address the air leak.
Explanation:Continuous bubbling in the suction control chamber of a closed chest drainage system indicates an air leak. In a client who is 1 day post thoracotomy, this could be due to a variety of reasons such as a disconnected or loose chest tube, a damaged chest tube, or an insecure connection between the chest tube and the drainage system. The nurse should assess the client's condition, check the chest tube and connections for any issues, and notify the healthcare provider to address the air leak.
