Answer:
Here are the 3 structures:-
Explanation:
The three structures that various protozoa may use for locomotion are:
Flagella: long, whip-like appendages that propel the protozoa by rotating or undulating.
Cilia: short, hair-like projections that cover the surface of the protozoa and move in a coordinated manner to create a current or a wave.
Pseudopodia: temporary extensions of the cytoplasm that push or pull the protozoa by changing shape and direction.
Protozoa use different structures for locomotion including flagella, cilia, and pseudopodia. Flagella are whip-like structures that some protozoa use to move around. Cilia are shorter and more numerous, aiding in movement and food collection. Pseudopodia, 'false feet', are temporary cell projections used for movement.
Various protozoa use different structures for locomotion, which allows them to move around their environment. Three primary structures used for movement include:

Burning fossil fuels causes a direct increase in the temperatures of ocean water.
b.
Burning fossil fuels causes a decrease in the pH of ocean water making it more acidic.
c.
Pollution in marine ecosystems causes a decrease in the formation of algal blooms.
d.
Addition of warm water has no effect on marine ecosystems.
Answer is b. Burning fossil fuels causes a decrease in the pH of ocean water making it more acidic.
Burning of fossil fuels release carbon dioxide and other harmful gases in the atmosphere. Carbon dioxide gets dissolves in the ocean to form carbonic acid. Due to formation carbonic acid, the pH of ocean water changes slightly. The average pH of ocean water was 8.2 slightly basic. Now it 8.1, it means there is 25 % increase in acidity of ocean water.
The True statement about the effect of pollution on marine ecosystem is : Burning fossil fuels causes a decrease in the pH of ocean water making it more acidic ( B )
When we Burn fossil fuels carbon dioxide and other harmful gases are released into the atmosphere.The Carbon dioxide gases gets dissolves in the ocean to form carbonic acid. The formation of carbonic acid leads to a change in the pH level of the ocean.
Hence we can conclude that The True statement about the effect of pollution on marine ecosystem is : Burning fossil fuels causes a decrease in the pH of ocean water making it more acidic ( B )

Answer:
Evolutionists.
Explanation:
Charles Darwin is known as the father of evolution. Evolution may be defined as the change in the organisms over generation with time. The natural selection acts as he main driving force in evolution.
The scientists that work to explain the evolution are known as evolutionists. They work on the evolution of life on earth and how the man has evolved first in the life. Evolutionists are the one who believe that man developed from a lower form of life.
Thus, the correct answer is option (1).
black fur
Himalayan Rabbit
A scientist shaved an area of white fur on the back of a Himalayan rabbit and placed an ice
pack over the shaved area. The shaved area grew black fur.
Which of these best explains why the hair that grew back where the ice pack was placed was
black and not white?
F The genes for black hair were activated by specific temperatures.
G The white hair mutated to black hair as the rabbit's body temperature decreased.
H The coat color changed from white to black with the age of the rabbit.
3 White hair only grows during certain times of the year.
Rabbits regulate their body temperature by using their ears. A fever or a dip in body temperature could be indicated by extremely chilly or hot ears. Thus, option F is correct.
In general, rabbits thrive in cooler climates. In the fall, rabbits stop shedding their fur and develop a thick coat of fur that keeps them warm in the winter. Low temperatures of 32 degrees don't really bother them.
Strong back legs offer rabbits the speed they need to run away from predators. Their feet have fur on the bottoms for warmth and strong claws for traction.
The white hair only grows in cold temperatures. Just because they put an ice pack on the rabbit does not mean that it's cold.
Therefore, The genes for black hair were activated by specific temperatures

F. The genes for black hair were activated by specific temperatures
Explanation:
The white hair only grows in cold temperatures. Just because they put an ice pack on the rabbit does not mean that its cold.
Answer:
In anaerobic respiration, one molecule of glucose is broken down into two molecules of ethanol (in yeast) or lactic acid (in muscle cells) with a net gain of two molecules of ATP (adenosine triphosphate).
Two molecules of carbon dioxide are released as the byproduct.
It helps in regenerating the NAD⁺ lost in the process of glycolysis.
The overall process is termed as fermentation.
Lactic acid fermentation is catalyzed by the enzyme lactate dehydrogenase and alcohol (ethanol) fermentation is a two-step process which is catalyzed by pyruvate decarboxylase and alcohol dehydrogenase.
