Many surface military ships use sonar as one method for detecting submarines. How would the temperature, density, and salinity of water affect the usefulness of sonar,and why?
Answer: Density
Explanation:
Actually those three things are really just one thing. Density.
Temperature affects density.
Salinity affects density.
Density affects the speed of sound through water.
Alterations to the speed of sound through water alter the path of soundwaves propagating through the water.
Sooo…
With increasing depth, comes decreasing temps as water gets colder the deeper you go. Cold water is denser than warm. Sound waves angled down into the depths eventually become curved back towards the surface.
This creates a rather interesting effect. While a sonar could normally detect a target at a certain range or less, these “Convergence Zones” where sonar waves are reflected back to the surface create annular rings of detection beyond the normal detection range.
This bending of soundwaves can also create “dead zone” where the soud waves just do not reach from a particular location. creating sound shadows where the sonar does not see.
In many locations in deep water, there can be a sudden shift in the rate of temperature change, usually located between the upper part of the ocean where temps can vary with seasons and the lower Isothermic layer where the temps change very little. This creates a layer called the thermocline Sonar detection across the layer Where the sonar and target lay on opposite sides, above and below the layer…is reduced compared to sonar detection where both sonar and target are on the same side of a layer.
So the temperature of water, which varies widely with depth, can cause the ray path of soundwaves to bend and reflect and even converge, creating both increased areas of detection as well as blind zones of reduced detection.
Salinity also affects density, With salt water being denser than Freshwater.
So areas wher there is a high degree of turbidity and mixing of these two types of water, like near the mouth of a large volume discharge of water, can create very unpredictable sound channels that are constantly changing. this make sonar performance prediction very difficult and affects the Sonar’s ability to detect targets.
Your friend claims that a pyramid of biomass may not have a the same shape as a pyramid of numbers
One of the three diagrammatic representations of the ecosystem used in ecology is a pyramid of numbers. The total number of species at every level of the food chain can be seen in such a picture. Since the biomass is not taken into account, it does not necessarily have a regular pyramidal shape.
The ecological pyramids are diagrams with a pyramidal structure that explain the relationships and energy flow between various species in an ecosystem. The producers, which are the species that produce food or energy for their life, make up the lowest layer of the pyramid. Other species, known as the consumers, make up the layer above the producers and consume the producers. When a result, there is only a slight energy waste in the environment as energy moves from producers to consumers. Each level of this phenomenon's food chain is referred to as a trophic level.To know more about biomass visit:

Some species of hares are brown most of the year, but change color to white in the winter. This allows them to
blend in through the seasons.
Where are these organisms adapted to live?
A deciduous forests
B desert
C tropical rain forests
D savanna
Explanation:
c is the answer of the question.
Some species of hares are brown most of the year, but change color to white in the winter. This allows them to
blend in through the seasons.
Hares that are brown in summer turn white in winter . This allows them to blend in Desert seasons (both hot and cold) . Therefore, option ( B ) is correct.
What is adaptation ?Adaptation is defined as "the physical or behavioral characteristic of an organism that helps an organism to survive better in the surrounding environment." All living things have become adapted to the habitat in which they have chosen to make their home. This is due to the fact that they possess unique characteristics that aid in their ability to adapt.
There is a fascinating adaptation that snowshoe hares have developed that helps them avoid being eaten by predators. Their fur can take on a variety of colors throughout the year depending on the weather. Snowshoe hares have white fur in the winter, which allows them to blend in better with the snowy environment. The snowshoe hare's coat takes on a rusty-brown color during the spring and summer months as the seasons change.

Describe the role of nitrogen fixation in the tissue formation of producer organisms
Microorganisms that fix nitrogen in nitrogen fixation can obtain assimilative [tex]N[/tex] for plants in a way that crops cannot. It is absorbed by bacteria from the atmosphere as a gas and released to the soil, mostly as ammonia.
The purpose of nitrogen-fixing bacteria is to provide plants with a crucial nutrient that they are unable to receive naturally from the air. The process by which nitrogen gas ([tex]N_{2}[/tex]) from the environment is integrated into the tissue of specific plants is known as biological nitrogen fixation (BNF). Using soil microorganisms as a source of [tex]N[/tex], only a small subset of plants can do so. Nitrogen fixers, nitrifying bacteria, and denitrifying bacteria, including Rhizobium, Nitrosomonas, Nitrobacter, Pseudomonas, and Thiobacillus, are among the organisms that participate in the nitrogen cycle. The majority of nitrogen fixation is done spontaneously by bacteria in the soil. In the soil, nitrogen is fixed and exchanged in several forms. Some bacteria adhere to root growth and form symbiotic relationships with plants that are advantageous to both the crop and the bacterium.

The CSI effect was first described in the media as a phenomenon resulting from watching forensic and crime programs on television. This effect causes jurors to have unrealistic expectations of forensics during criminal trials, influencing juror decisions during the conviction or acquittal process. CSI viewers rated the hair evidence as unreliable. This is a statistically significant difference compared to non-viewers.
Schweitzer and Saks' findings suggest that consideration of CSI may influence jurors' attitudes to forensic evidence. The first police crime laboratory was founded in Lyon, France in 1910 by Edmond Locard.

Which of Earth's spheres are involved in the water cycle?
T A. Atmosphere, lithosphere, hydrosphere, and biosphere
B. Atmosphere, lithosphere, and hydrosphere only
C. Atmosphere and lithosphere only
D. Atmosphere, hydrosphere, and biosphere only
Explanation:
Water sustains life and is an important link between each of the four "spheres" of the Earth system (hydrosphere, atmosphere, pedosphere, biosphere)
The water cycle is the continuous movement of water on, above, and below the surface of the Earth. It is driven by the Sun's energy and involves all four of Earth's spheres: the atmosphere, the lithosphere, the hydrosphere, and the biosphere. Hence option A is correct.
The atmosphere is involved in the water cycle because it contains water vapor. Water vapor rises into the atmosphere and condenses to form clouds.
The clouds then release water back to Earth in the form of precipitation, such as rain, snow, or hail.
The lithosphere is involved in the water cycle because it contains water in the form of groundwater, lakes, rivers, and oceans.
Water evaporates from the surface of the Earth and enters the atmosphere. It then condenses to form clouds and falls back to Earth as precipitation.
The hydrosphere is involved in the water cycle because it contains all of the water on Earth.
The water in the hydrosphere is constantly moving from one place to another, through the processes of evaporation, condensation, precipitation, and runoff.
Therefore option A) Atmosphere, lithosphere, hydrosphere, and biosphere is correct.
