A student claims, "Scientific knowledge that changes cannot be trusted." Which statement best corrects this student's claim?
New evidence changes our scientific knowledge and that strengthens our understanding.
A change in scientific knowledge means we should ignore our previous understanding.
Testing and examining scientific knowledge frequently make it unreliable.
Scientific knowledge cannot change making it always true.
Answers
The statement that best corrects the student's claim that "Scientific knowledge that changes cannot be trusted" is "New evidence changes our scientific knowledge and that strengthens our understanding.
Science is based on experimentation, observation, and evidence. Scientific knowledge is the collection of data and information obtained by this process. New evidence, data, and technology advance our understanding of the world and help us correct previous assumptions.
Therefore, the statement that best corrects the student's claim that "Scientific knowledge that changes cannot be trusted" is "New evidence changes our scientific knowledge and that strengthens our understanding."It is important to note that changes in scientific knowledge are the result of new discoveries and better understandings of natural processes.
New evidence strengthens and develops scientific knowledge by refining previously held assumptions. This does not mean that science is unreliable, but that it is constantly evolving and improving as new information becomes available.

According to the research, the correct option is genus. A classification grouping that consists of a number of similar, closely related species is called a genus.
What is a genus?It is a taxonomic category that is part of systematic biology, which is located between the family and the species, that is, it includes many species that are related to each other.
In this sense, it is a taxon that allows living beings to be classified based on a hierarchy of inclusion, in this case grouping together closely related species, being a group of organisms that in turn can be divided into several species.

What effect does the Earth's surface have on solar radiation?
The ground doesn't absorbs any of the solar radiation.
The ground absorbs half the solar radiation and stores it as infrared radiation for centuries.
Half of the solar radiation is absorbed and converted to infrared (heat).
Nearly all solar radiation is reflected back into space by the ground.
Answers
Answer:
Half of the solar radiation is absorbed and converted to infrared (heat).
Explanation:
What is solar radiation?Solar radiation is the energy emitted by the Sun in all directions through space as electromagnetic waves.
The Earth’s surface has a significant impact on solar radiation.
When solar radiation reaches the Earth’s surface, it warms it up. However, the Earth’s average temperature does not change because the Earth radiates energy to the atmosphere and space. The outgoing radiation is at the Earth’s temperature and has its maximum in the infrared region of the spectrum.
Almost all solar radiation is absorbed by the ground, but only half of it is converted to infrared (heat). The other half is reflected back into space by the ground.

The statement that would correctly explains the weight you would experience on each planet is You would weigh less on planet A because it has less mass than planet B. Option D
How does mass affect weight?Weight is the force experienced by an object or person due to gravity. Since it is as a result of gravitational force, it depnds on both the mass of the objct or person and the level of gravity of the planet.
Gravity is dependent on th mass of the planet, and if planet A has lesser the mass of planet B, its gravitational force will be most likly be weaker.
This therefore means a person is going to weigh less on planet A than on planet B, even though both planets have the same size.

Explanation:
Carbon dioxide is one of the most common atmospheric gases. It is naturally produced into the atmosphere in the following ways:
- via cellular respiration in organisms
- forest fires
- volcanic eruption
- decomposition of dead matter (plants and animals)
The release of CO2 gas into the atmosphere by one or all of the above listed ways poses a great threat to the environment as it causes a type of pollution. CO2 causes pollution by being a greenhouse gas i.e gases capable of trapping heat. This results or contributes to global warming in the atmosphere.

The legal system has exhibited a limited recognition of cohabitation through
Answers
The legal system has exhibited a limited recognition of cohabitation through various means, such as the establishment of common-law marriage or the introduction of specific legislation addressing cohabiting couples.
Common-law marriage is a legal concept that recognizes a couple as married even if they have not undergone a formal marriage ceremony. In some jurisdictions, cohabiting couples who meet specific criteria, such as living together for a certain period of time and presenting themselves as a married couple, may be granted legal rights and responsibilities similar to those of traditionally married couples.
Additionally, some jurisdictions have introduced legislation to address the legal rights and obligations of cohabiting couples. These laws may grant certain rights related to property, inheritance, healthcare decision-making, and child custody. However, the extent of recognition and protection varies across different jurisdictions, and many legal systems still do not fully address the complexities of cohabitation.
Overall, while progress has been made in recognizing cohabitation in the legal system, there remains a limited and inconsistent recognition of the rights and obligations of cohabiting couples, highlighting the need for further development and refinement of laws to reflect the realities of modern relationships.

9. What is the approximate dewpoint
temperature when the dry-bulb reading is
14°C and the wet-bulb reading is 8°C?
A) 1°C
B) 6°C
C) -6°C
D) -9°C
Answers
The given wet-bulb depression of 6°C, the approximate dew point temperature would be around 6°C. Option B
What is the temperature?You must compute the wet-bulb depression, which is the difference between the dry-bulb temperature and the wet-bulb temperature, in order to estimate the approximate dew point temperature.
Dry-bulb temperature = Wet-bulb depression - Temperature of a wet bulb
Wet-bulb depression in this instance equals 14°C - 8°C = 6°C.
The temperature differential brought on by moisture evaporating from the wet-bulb thermometer is represented by the wet-bulb depression. You can determine the dew point temperature by comparing this number to a table or chart that uses psychrometric measurements.

which adaptions woud be more advantogeous to a desert-dwelling organism than to a rain forest dwelling organism
Answers
An adaptation that would be more advantageous to a desert-dwelling organism than to a rainforest-dwelling organism is the ability to conserve water.
In a desert environment, water scarcity is a significant challenge for organisms. Therefore, adaptations that enable efficient water conservation would be highly advantageous.
Desert-dwelling organisms may have features such as specialized kidneys to concentrate urine, reduced sweat glands to minimize water loss through perspiration, or the ability to extract water from the food they consume.
These adaptations help them survive in arid conditions by reducing water loss and maximizing water retention within their bodies.
On the other hand, rainforest-dwelling organisms face a completely different set of challenges. The rainforest is characterized by high humidity and abundant rainfall. As a result, water availability is not a limiting factor for survival.
Organisms in the rainforest may have adaptations that promote efficient heat dissipation, such as larger surface areas for evaporative cooling or increased perspiration.
These adaptations are advantageous in a high-moisture environment where excessive heat and humidity can pose challenges to thermoregulation.
Therefore, the ability to conserve water would be more advantageous to a desert-dwelling organism as compared to a rainforest-dwelling organism, given the contrasting water availability and environmental conditions in these two habitats.

Answers
Answer:
B. The 55 N cat has less mass than the 110 N dog.
Explanation:
Weight of an object refers to the product of its mass and the force of gravity. However, the greater that mass of an object, the greater the weight of that object.
In this case, the cat's weight is 55N while the dog's weight is 110N. This means that the dog has a greater mass than the cat or alternatively put, the 55 N cat has less mass than the 110 N dog.
Note that: if the gravitational effect is removed, the cat will contain lesser mass.
