noun
a system for the detection of objects under water and for measuring the water's depth by emitting sound pulses and detecting or measuring their return after being reflected.
"a weak sonar signal"
Answer:
0.3106 seconds
Explanation:
Frequency= 20,000-Hz
The speed of echoes sounds can be calculated using the expression below;
Y= ( 2x/t) ...........................eqn(1)
t= overall time taken
x = maximum depth = 230m
Y= speed of echoes sounds
Speed of sound in water= 1,481 m/s which is a constant with little variation.
If we substitute the given values into eqn(1) we have
1481 = (2× 230)/ t
1481 × t= 460
t=460/1481
t=0.3106 seconds
Hence, the minimum time between pulses (in fresh water) is 0.3106 seconds

In Culinary class, Jennifer roads a recipe that noods wited spinach and decides to use salt to propare the leaves. She places the spinach in a solution of 8% salt, which causes the plant cols to shrink
since they normally have an internal salt concentration of 0.9% salt. Which statement best explains why the cells shrink?
Sall causes the cell membrane to swet and absorb water trom the cytoplam
Sat moves from the 8 sal solution into the cell and chemically bind with water
Water moestrom the cell through the cell membrane to an area of lower water concentration
O Water moves from a lower concentration of water in colis cytoplasm into the nucles and colorganelles
The cell shrinks because of the movement of water away from the cell into the more concentrated salt solution.
Osmosis is the movement of water from one region to another through a semi - permeable membrane. A hypertonic solution contains more solute than the cell.
In this case, the external salt solution is hypertonic because it contains a 8% salt concentration whereas the cell contains only a 0.9% salt concentration. As such, water moves out of the cell into the solution.
The cell shrinks because of the movement of water away from the cell into the more concentrated salt solution.

What is Ecological Sustainability? What happens if we use all of our planet's resources without replacing them?
Answer:
Ecologically sustainable development is the environmental component of sustainable development. It can be achieved partially through the use of the precautionary principle. The precautionary principle (or precautionary approach) is a broad epistemological, philosophical and legal approach to innovations with potential for causing harm when extensive scientific knowledge on the matter is lacking. It emphasizes caution, pausing and review before leaping into new innovations that may prove disastrous

Which of the following is a sign of food spoilage?
-a. Soil on unwashed vegetables
-b. Bruised fruit
-c. Bulging or leaking cans
-d. Cloudy egg whites (albumin)
The sign that shows food spoilage is bulging or leaking cans. That is option C.
Food substances can be stored or preserved to prolong the nutritive values and shelf life of the food.
Food spoilage occurs when environmental factors such as:
Light, oxygen, heat, humidity, temperature and spoilage bacteriacauses food to become unsuitable for consumption.
For canned products, bulging or leaking cans shows the food content has deteriorated.
This shows some ongoing fermentation by a spoilage bacteria causing the can to bulge and eventually leak out.
Therefore, the sign that shows food spoilage is bulging or leaking cans.

Does the light independent pathway of photosynthesis continue to occur when the leaf disks are placed in the dark environment
Yes, the light independent pathway of photosynthesis continues to occur when the leaf disks are placed in the dark environment.
What is photosynthesis?“The process by which green plants make their own food in presence of sunlight, chlorophyll and carbon dioxide is called photosynthesis.”In this process oxygen molecule is released as by product.It has two pathways: light dependent and light independent.
In light dependent pathway, light energy is used by chlorophyll and is converted into chemical energy.In light independent pathway, the energy produced during light dependent pathway is used to convert carbon dioxide into carbohydrates. It occurs in the stroma of the chloroplast.Hence, it is true that the light independent pathway of photosynthesis continues to occur when the leaf disks are placed in the dark environment.

All living things have internal that helps them carry out basic functions.
true
................................
Answer:
True
Explanation:
By the end of grade 2. All organisms have external parts. Different animals use their body parts in different ways to see, hear, grasp objects, protect themselves, move from place to place, and seek, find, and take in food, water and air. Plants also have different parts (roots, stems, leaves, flowers, fruits) that help them survive, grow, and produce more plants.
By the end of grade 5. Plants and animals have both internal and external structures that serve various functions in growth, survival, behavior, and reproduction. (Boundary: Stress at this grade level is on understanding the macroscale systems and their function, not microscopic processes.)
By the end of grade 8. All living things are made up of cells, which is the smallest unit that can be said to be alive. An organism may consist of one single cell (unicellular) or many different numbers and types of cells (multicellular). Unicellular organisms (microorganisms), like multicellular organisms, need food, water, a way to dispose of waste, and an environment in which they can live.
Within cells, special structures are responsible for particular functions, and the cell membrane forms the boundary that controls what enters and leaves the cell. In multicellular organisms, the body is a system of multiple interacting subsystems. These subsystems are groups of cells that work together to form tissues or organs that are specialized for particular body functions. (Boundary: At this grade level, only a few major cell structures should be introduced.)
By the end of grade 12. Systems of specialized cells within organisms help them perform the essential functions of life, which involve chemical reactions that take place between different types of molecules, such as water, proteins, carbohydrates, lipids, and nucleic acids. All cells contain genetic information in the form of DNA molecules. Genes are regions in the DNA that contain the instructions that code for the formation of proteins, which carry out most of the work of cells.
Multicellular organisms have a hierarchical structural organization, in which any one system is made up of numerous parts and is itself a component of the next level. Feedback mechanisms maintain a living system’s internal conditions within certain limits and mediate behaviors, allowing it to remain alive and functional even as external conditions change within some range. Outside that range (e.g., at a too high or too low external temperature, with too little food or water available), the organism cannot survive. Feedback mechanisms can encourage (through positive feedback) or discourage (negative feedback) what is going on inside the living system.
A central feature of life is that organisms grow, reproduce, and die. They have characteristic structures (anatomy and morphology), functions (molecular-scale processes to organism-level physiology), and behaviors (neurobiology and, for some animal species, psychology). Organisms and their parts are made of cells, which are the structural units of life and which themselves have molecular substructures that support their functioning. Organisms range in composition from a single cell (unicellular microorganisms) to multi-cellular organisms, in which different groups of large numbers of cells work together to form systems of tissues and organs (e.g., circulatory, respiratory, nervous, musculoskeletal), that are specialized for particular functions.
Special structures within cells are also responsible for specific cellular functions. The essential functions of a cell involve chemical reactions between many types of molecules, including water, proteins, carbohydrates, lipids, and nucleic acids. All cells contain genetic information, in the form of DNA. Genes are specific regions within the extremely large DNA molecules that form the chromosomes. Genes contain the instructions that code for the formation of molecules called proteins, which carry out most of the work of cells to perform the essential functions of life. That is, proteins provide structural components, serve as signaling devices, regulate cell activities, and determine the performance of cells through their enzymatic actions.
