The correct answers are:
- Decrease in rainfall in the Mojave desert;
The decrease in rainfall can be devastating to a lake's waters and biodiversity. The decrease in rain usually causes bigger loss of water through evaporation than water coming in the lake, so over time it will dry out, or just small pieces of it will remain.
- Decrease in runoff that flows into Mojave Lake;
If the amount of water that comes into the lake decreases, it can be fatal to it, and in a very short period of time, since the lake will be losing more water than it gets in.
- Increase in blocked streams that flow into Mojave Lake;
Naturally, streams can be blocked and redirected, so if this happens, we have the same situation from before, where the water income is smaller than the water loss of the lake.

Which situation would be most likely to cause a DNA mutation? A. A wood frog in a lake is exposed to temperatures below 0°C during the winter months. B. A person spends one hour each day under the ultraviolet rays of a tanning bed. C. A culture of cells is placed in a chamber and exposed to high pressure for 10 hours. D. A maple tree becomes dormant to prevent water loss during a drought.
The correct answer is: B. A person spends one hour each day under the ultraviolet rays of a tanning bed.
The relationships between ultraviolet (UV) light and skin cancer are highly positive because it has been shown that indoor tanning bed use represents an avoidable risk factor for melanoma and non-melanoma skin cancer. UV light is a form of radiation that causes mutations in DNA by causing the chemical changes that alter the shape of the DNA. So, UV light is a potent mutagen and thus, tanning bed (source of UV light) can cause damage to the DNA in the surface layer of your skin after repeated or prolonged exposure. This might increase the risk for skin cancer.
I just took this test recently and the answer is:
B - A person spends one hour each day under the ultraviolet rays of a tanning bed.
This could cause a genetic mutation in the skin cells and cause skin cancer.

03]The water in a location is tested regularly to identify contaminants. The nitrate levels in the water from 1994 to 1997 are shown in the table below. Years Nitrate level in water (in mg/L) 1994 8.5 1995 12.2 1996 9.7 1997 7.3 Which of these conclusions is most likely correct about the people in the location?
Answer:
Although the question is incomplete, missing options are
In 1997, they reduced their water consumption. In 1996, they planted more trees to curb water pollution. In 1994, they used only bottled water for drinking purpose. In 1995, they complained about foul odor and taste in water.Correct option: In 1996, they planted more trees to curb water pollution.
Explanation:
Among given options, a clear trend of nitrate level can be seen. Initially, the nitrate level increased in water in first two years (1994 and 1995) and then it decreased significantly.
From the conditions given in the question, the most probable answer is B the plantation effect (phytoremediation). During phytoremediation, plants take up nutrients including nitrate from the water via roots. This nitrogen is then used for the growth and development of plant body mass (e.g. amino acids). As more plants were growing in later years, higher reduction of nitrate was seen. Resultantly, in 1997, the concentration of nitrate was dropped to 7.3 mg/L.
The other options are not correct due to following reasons.
A. There is no information on water consumption in the question
C. There is no information on people's behavior on drinking water lifestyle.
D. Nitrate in the water cannot be smelled or tasted.
The nitrate levels from 1994 to 1997 indicate a possible health risk in 1995 when they exceeded 10 mg/L, associated with "blue baby syndrome." The data suggest varying health risks and the importance of water quality monitoring to ensure safety.
Explanation:The nitrate levels in water from 1994 to 1997 suggest that in 1995, the concentrations exceeded 10 mg/L, which is above the level that can cause health issues such as "blue baby syndrome" (acquired methemoglobinemia). In the European Union, drinking water quality standards require nitrate levels to be less than 50 mg/L, so even the highest recorded level (12.2 mg/L in 1995) was within EU standards but could still pose a risk to infants. Elevated nitrate levels can originate from sources like sewage sludge disposal, on-site sanitation, and agricultural activities.
Furthermore, nitrate contamination is a common issue globally, and high levels of nitrates are especially problematic in some low-income countries. As nitrate does not degrade easily in high oxygen conditions, it can persist in groundwater, affecting water quality over the long term. Clean-up efforts in various locations have shown varied success, with contamination remaining a significant issue in some places, such as with Cr(VI) in the water supply of certain US cities.
Given the data presented, it's likely that people living in this location may have experienced periods of increased health risks due to high nitrate levels, especially in 1995. The varying levels over these years could suggest changes or interventions in local practices or environmental conditions that impacted nitrate concentrations in the water supply. Continuous monitoring and adequate filtration are crucial to ensure the quality and safety of drinking water.

Which conclusions can be made about the animals of each class based on the structural similarities of the embryos?
Select ALL the correct answers.
1.There is an evolutionary link among the classes.
2.The adults of each class may share structural similarities.
3.Reptiles must have given rise to fish and amphibians.
4.Animals of each class have analogous structures.
Conclusions that can be made about the animals of each class based on the structural similarities of embryos include the presence of an evolutionary link among the classes and that they may share homologous structures. It is incorrect to conclude a direct lineage such as reptiles giving birth to fish and amphibians from embryology alone.
Explanation:Based on the structural similarities of embryos, multiple conclusions can be made about the animals of each class:
There is an evolutionary link among the classes, implying that animals with similar embryonic stages may have diverged from a common ancestor. This is evidenced by shared embryonic features such as gill slits and tail structures, which may disappear in adulthood but indicate a common lineage.The adults of each class may share structural similarities due to their embryological development, suggesting that these shared features are homologous structures inherited from a common ancestor.It is incorrect to conclude that Reptiles must have given rise to fish and amphibians based on embryology alone since the linear progression of species is not how evolution operates. Instead, these groups share common ancestors and have evolved separately.Embryonic similarities among different classes indicate that animals of each class have homologous structures, which are traits inherited from a common ancestor, reflecting evolutionary relationships rather than strictly analogous structures which serve similar functions but do not indicate common ancestry.The presence of similar embryonic stages across diverse groups of animals highlights the concept of evolution from a common ancestor and provides strong evidence for the relatedness of different classes of animals. By studying embryology, scientists can trace the evolutionary paths that have led to the diversity of life forms we see today.
The correct conclusions based on the structural similarities of the embryos are:
1. There is an evolutionary link among the classes.
2. The adults of each class may share structural similarities.
3. Animals of each class have analogous structures.
Based on the options given, the following judgements about the embryos' structural similarities are accurate:
1. There is a connection between the classes through evolution.
The fact that anatomical similarities in embryos frequently imply shared ancestry and evolutionary links between many animal taxa lends credence to this view.
2. There could be structural commonalities among the adults in each class.
This result is tenable because distinct classes of embryos frequently mature into adults with similar anatomical traits derived from their shared ancestry.
3. The structures of the animals in each class are similar.
Although this conclusion is not proved by the available data, it remains a possibility. When a feature in two or more species has a similar function but evolved separately—often as a result of comparable environmental pressures—rather than through common ancestry, it is referred to as an analogy.
As a result, given the embryos' structural similarities, alternatives 1, 2, and 3 are accurate. The available data does not directly support Option 4.
If a sealed balloon is filled and kept in a deep freezer for a period of time, it will shrink in size. Determine the best reasoning for this outcome. A) The air particles inside the balloon slow down due to lower thermal energy. As a result, fewer collisions take place per second and this leads to a lower pressure inside the balloon. The pressure on the outside of the balloon pushes the balloon to a smaller volume. B) The air particles inside the balloon slow down due to lower thermal energy. As a result, the air particles become charged, attract to each other and take up a smaller volume. Therefore, the balloon shrinks. C) The rubber latex of the balloon becomes colder and will resist stretching and push the air particles inward until the inside pressure equals the outside pressure and equilibrium is established. D) The density of the air particles increases within the balloon causing some particles to escape out of the balloon. This leads to an increase in the particles and, thus, pressure outside the balloon. This causes the balloon to collapse.
Answer:
The air particles inside the ballon slow down due to lower thermal energy. As a result, fewer collisions take place per second and this leads to a lower pressure inside the balloon. The pressure on the outside of the balloon pushes the balloon to a smaller volume.
Explanation:
When particles are excited by an increase in thermal energy they tend to vibrate more and collide. The charged partcles repel each other making them occupy a bigger volume. When the balloon is placed in a deep freezer, the energy is lost to the surrounding thus the particles come together occupying a smaller volume hence the size of the balloon decreases.
Answer:
A) The air particles inside the balloon slow down due to lower thermal energy. As a result, fewer collisions take place per second and this leads to a lower pressure inside the balloon. The pressure on the outside of the balloon pushes the balloon to a smaller volume.

B. A location that receives a large amount of snow
C. A location that receives a large amount of radiation
D. A location that is frequently cloudy
Answer:
Option “C”.
Explanation:
A location that receives a large amount of radiation.

If this propane tank is opened inside a house, the atoms in the tank immediately spread throughout the whole house. Propane is most likely a solid. liquid. gas. plasma.
The right option is; gas
Propane is most likely a gas.
Propane gas is a flammable hydrocarbon, and one of the liquefied petroleum gases. Propane is produced from petroleum refining and natural gas processing. Propane gas can be liquefied at very low pressures. Propane is commonly used as fuel in cooking, heating, and also for aerosol propellants, refrigerants, and in motor vehicles.
Propane is a gas that is often used for heating and cooking, and it is stored as a liquid under pressure.
If a propane tank is opened inside a house, the atoms from the tank will quickly spread throughout the house. This behavior is characteristic of a gas, which is one of the states of matter. Propane, with its molecular formula C3H8, is indeed commonly used as a gaseous fuel. At room temperature and under moderate pressure, propane is typically stored as a liquid in tanks, but when it is released, it becomes a gas. This change occurs because propane, while it liquefies under pressure, will vaporize and expand to fill the available space once the pressure is removed and the propane is exposed to normal atmospheric conditions.
Propane is an efficient energy source and is used in situations where natural gas pipelines are not available. It is also known for its use in barbecue grills and various heating applications. Propane's ability to be compressed into a liquid form greatly facilitates its storage and transportation. When released, it expands and is used as a gas.

A.
Olive oil can be used as an adhesive between two solid objects.
B.
The oil reduced the friction between the floor and his mother's foot.
C.
Trevor's mother slipped on the spot where he dropped the oil.
D.
The oil increased the gravitational force on his mother's foot.
Answer:
B.
The oil reduced the friction between the floor and his mother's foot.
Explanation:
When things slide, it is just fancy terms for one of two things- force exceeding the amount of friction on the ground, or the friction decreasing itself.
In the question, it is implied that Trevor's mom is walking completely normal, excluding the olive oil; therefore, there is no force exceeding what the friction of the ground can prevent from sliding. This leaves the other option, which implies that the olive oil decreased the friction between the floor and his mother's foot, which makes sense as olive oil is a lubricant.
Henceforth, the answer is B. The oil reduced the friction between the floor and his mother's foot.
Answer:
The oil reduced the friction between the floor and his mother's foot.

What property of water refers to water's ability to move up the stem of a plant against the force of gravity?
Surface tension
Cohesion
Adhesion
Capillary action
Answer:
Or i think its capillary action
Explanation:
Capillary action (sometimes capillarity, capillary motion, capillary effect, or wicking) is the ability of a liquid to flow in narrow spaces without the assistance of, or even in opposition to, external forces like gravity. The effect can be seen in the drawing up of liquids between the hairs of a paint-brush, in a thin tube, in porous materials such as paper and plaster, in some non-porous materials such as sand and liquefied carbon fiber, or in a biological cell. It occurs because of intermolecular forces between the liquid and surrounding solid surfaces. If the diameter of the tube is sufficiently small, then the combination of surface tension (which is caused by cohesion within the liquid) and adhesive forces between the liquid and container wall act to propel the liquid.
