Answer:
they are better for camoflauge and for deep pressure
Explanation:
the fins helps control the crushing pressure that is constant at deep depths and the flattened bodies make them less visible since it is dark
Bottom-oriented fish have large, broad pectoral fins and depressed (flattened top-to-bottom) body shapes.These adaptations are well suited for life at the bottom of a body of water.
What is adaptation?Adaptation refers to the process where organisms inherit traits that help for better survival and reproduction in its environment.The large, broad pectoral fins and depressed body shapes of bottom-oriented fish are well-suited for life at the bottom of a body of water for several reasons:
The broad pectoral fins provide the fish with greater surface area, which allows them to maintain their position and stability while resting on the bottom of the water body The depressed body shape of these fish allows them to minimize their profile and reduce their exposure to the water current.Hence, the large, broad pectoral fins and depressed body shapes of bottom-oriented fish are adaptations that help them to survive and thrive in the challenging conditions of the bottom of a body of water.

Which of the following is an example of a physical variable of water quality *
Answer: Physical properties of water quality include temperature and turbidity. While chemical characteristics involve parameters such as pH and dissolved oxygen. These parameters are relevant not only to surface water studies of the ocean, lakes and rivers, but to groundwater and industrial processes as well.
I hope this is the answer if not I apologize :P
Answer:
One of the physical variables that affect the properties of water is temperature
Explanation:
I assume that by physical properties you mean external factors that affect the properties of the water correct? well depending on the temperature of the air that the water is exposed to the war can shift from either a liquid to a solid if it if the air is cold or it can change from a liquid to a gas when the air is hot. I'll explain how this works when the temperature of the air is hot the water will under go an exo thermic reaction (A reaction that causes things to emit heat and become hot) and because water boils at a certain point as the water gets hotter and hotter it will evaporate into mist. If the air around the water is cold then it produces an endothermic reaction which will cause the ice to get colder and colder as time goes on until it transitions from being a liquid to a solid in the form of ice. Hope this helps:)
Why do fish and frogs lay eggs in hundreds whereas a hen lays only one egg at a time?
Answer:
bc there eggs are tinnier then a hens egg
Explanation:
Answer:
Animals like frogs and fish lay hundreds of eggs and release millions of sperms. But the entire eggs do not get fertilized and develop into new individuals. This is because the eggs and sperms get exposed to water movement, wind and rainfall. Also, there are other animals in the pond which may feed on eggs. Thus, production of large number of eggs and sperms is necessary to ensure fertilization of at least a few of them.

Plant and animal cells have many organelles in common such as the cell membrane. However, the function of the cell membrane differs between the plant and the animal cell. Which best describes how the function of the cell membrane differs in plant and animal cells?
A. In animal cells, the cell membrane is the outermost layer of the cell, while in plant cells, the cell membrane separates the cell wall from everything inside the cell.
B. In plant cells, the cell membrane is the outermost layer of the cell, while in animal cells, the cell membrane separates the cell wall from everything inside the cell.
C. In animal cells, the cell membrane controls what comes in and out of the cell, while in plant cells, the cell membrane houses all the genetic material.
D. In plant cells, the cell membrane is made of a gel-like material that is green, while in animal cells, the cell membrane is made of a gel-like material that is red.
In plant cells, the cell membrane is the outermost layer of the cell, while in animal cells, the cell membrane separates the cell wall from everything inside the cell. Thus option B is correct.
What are the function of plant cell wall ?
Plant Cell wall is composed of cellulose which is a sugar which is a rigid structure that provides support and protection to the plant cell from any external damage.
Mechanical strength can be provided due to the presence of skeletal framework in cellulosic microfibrils.
The various shapes of plant cell due to cell wall, the additional wall component include pectin and/or lignin
Growth of plant cell can also depends on the elastic and plastic nature of cell walls.
The transport of intracellular substances between plant cells can be done by cell wall.
It occurs in two ways such as apoplastic and symplastic transport.

many cellular functions can be compared with functions that occur in organisms. which is not a function that both cell and an organism share. A stores waste material for removal B provides structure and support C learn behaviors that aid in survival D conversion of nutrients into usable energy
Answer:
learn behaviors that aid in survival
Explanation:
learn behaviors that aid in survival is not a function that both a cell and organism share because a cell is a basic unit of life and contains some organelles that perform little functions while an organism comprises of many specialised cells that work to perform similar functions. An organism have central nervous system which comprises of brain and spinal cord. Organisms learn new behavior and acquire cognitive skills through the brain development. The brain and spinal cord receive electrical impulses sent from neurons and interpret it to meaningful information.
Learning behaviors that aid in survival is not a function that both cell and an organism share.
LEVEL OF ORGANIZATION:The cell is the basic and functional unit of living organisms. This means that the cell harbors the functional characteristics of living organism.

The process in which populations change over time is evolution, the change in the characteristics of a species over several generations and relies on the process of natural selection.
What is natural selection?
Natural selection is the method through which denizens of living organisms adapt and modify. peoples in a population are inherently variable, meaning that they are all various in some ways.
This divergence means that some people have traits nicely suited to the environment than others.

which two body systems interact to expel the waste product carbon dioxide
a urinary system
b nervous system
c excretory system
d circulatory system
Answer:
excretory system and circulatory system
Explanation:
Blood is part of circulatory system and as it move through various organs it exchanges the gases i.e give oxygen to the cell and take carbon dioxide from them. After taking CO2, the blood becomes impure and hence it passes through the kidney before going to the heart. Kidney is part of excretory system which removes carbon dioxide from blood and thus purifies it.

How does the process of gel electrophoresis produce DNA fingerprints? An electric current sorts DNA nucleotides according to their bases. O An electric current cuts a DNA strand into segments of various lengths O An electric current causes segments of DNA to move at different rates O An electric current supplies a charge to uncharged segments of DNA
Answer:
Gel electrophoresis
Explanation:
Gel electrophoresis is a technique used to separate DNA fragments according to their size. DNA samples are loaded into wells (indentations) at one end of a gel, and an electric current is applied to pull them through the gel. DNA fragments are negatively charged, so they move towards the positive electrode.
