An echolocation refers to a method that relies on sound waves and is used by different animal species for navigation, communication, and finding food. Therefore, option A is correct.

Echolocation is a method used by bats, dolphins, and other animals to locate objects using reflected sound. This enables the animals to move around in complete darkness, allowing them to navigate, hunt, recognize friends and enemies, and avoid obstacles.

(1) To hunt for prey, bats make high-frequency sounds. (2) Sound waves are used by dolphins and other toothed whales to locate prey and navigate their surroundings. (3) Nocturnal oil birds use echolocation to navigate their surroundings, particularly in low-light conditions.

Echolocation is used to help with orientation, obstacle avoidance, food acquisition, and social interactions.

Thus, option A is correct.

Explanation:

During freezing, water molecules lose energy and do not vibrate or move around as vigorously. This allows more stable hydrogen-bonds to form between water molecules, as there is less energy to break the bonds. ... Thus water expands as it freezes, and ice floats atop water.

When water molecule freezes, the water molecules have slowed down enough that their attractions fixed them into fixed positions.

The term freezing is defined as a phase transition where a liquid converted into a solid when its temperature is lowered below its freezing point.

The freezing point is the temperature at which a liquid turns solid. In the freezer, for example, water-filled ice cube trays.

Water molecules freeze in a hexagonal pattern, with molecules further apart than when the water was liquid. It is worth noting that the molecules in ice would be vibrating.

Thus, When water freezes, the water molecules slow down to the point where their attractions arrange them into fixed positions.

D. A federal government agency publishes an article in a professional scientific journal detailing technical details of a  new virus.

Explanation:

Public scientific communication is a way used by scientists to make the audience able to understand the basics of science to communicate an informed decision. There are several skills under public scientific communication that include connect with the public, talk to journalists, make science understandable, and understand the audience.

The best way to connect with the audience is to publish an article in a professional scientific journal because mostly journals are peer-reviewed having standard of quality.

A federal government agency informing about a  new virus through an article in a professional scientific journal is the best way of public scientific communication as it will be for a specific audience along with a standard of quality.

Scientific notation:

Scientific notation is the way to express the large value in short form.

The number in scientific notation have two parts.

The digits (decimal point will place after first digit)

× 10 ( the power which put the decimal point where it should be)

for example the number 6324.4 in scientific notation will be written as = 6.3244 × 10³

When we multiply or divide the values the number of significant figures must be equal to the less number of significant figures in given value.  Thus, in given value,

(4.1357× 10⁻¹⁵) × (5.4×10²)

22×10⁻¹³

Answer: Its B/Climate

Im pretty sure if its wrong srry!

Hope this helped!

Explanation:

Apart from different ways to classify soils. The one factor that scientists use to classify orders of soil is climate. Hence, Option (B) is correct

Climate is the long-term pattern of weather in a particular area.

Weather can change from hour-to-hour, day-to-day, month-to-month or even year-to-year.

A region's weather patterns, usually tracked for at least 30 years, are considered its climate.

Other factors people uses in classifying orders of soil are;

Soil orders are known as the single dominant attributes affecting soils in any location.

They can be the prevalent vegetation such as Alfisols and Mollisols or the type of parent material such as Andisols and Vertisols or the climate variables such as lack of precipitation etc.

Answer:

12341 in standard form = 1.2341 × 10⁴

Explanation:

When you split the number 12341 into a coefficient and a power of 10 you do get 12341 in exponential form, but there is an indefinite number of possibilities.

As you probably want 12341 in normalized scientific notation, the coefficient or significand of 12341 in scientific notation must be in the interval [1,10[.

As there are many ways to express 12341 in scientific notation, in this post we mean 12341 in normalized scientific notation, unless stated otherwise. Therefore:

12341 in scientific notation = 1.2341 × 10⁴.

This can also be expressed as 1.2341 × 10⁴, using the caret symbol, or as 1.2341e+4, which is called 12341 in e-notation.

Answer:

7.49 × 108

Explanation:

Scientific notation is a way to express numbers in a form that makes numbers that are too small or too large more convenient to write. It is commonly used in mathematics, engineering, and science, as it can help simplify arithmetic operations. In scientific notation, numbers are written as a base, b, referred to as the significant, multiplied by 10 raised to an integer exponent, n, which is referred to as the order of magnitude:

Distance is a scalar quantity that refers to "how much ground an object has covered" during its motion. Displacement is a vector quantity that refers to "how far out of place an object is"; it is the object's overall change in position.
