Answer: I do think its a good idea cause it lessens pollution in the air we breathe in and stops us from burning fossil fuels
Explanation:
Banning passenger cars and promoting public transportation in cities is a good idea for reducing pollution and traffic congestion.
I believe that banning passenger cars and promoting the use of public transportation in cities is a good idea. This approach can help reduce air and noise pollution, alleviate traffic congestion, and improve overall quality of life. By encouraging people to walk, bike, or use public transportation, cities can create a more sustainable and livable environment for their residents.
One example of a city that has successfully implemented this approach is Copenhagen, Denmark. The city has an extensive public transportation system, including a well-connected network of bike lanes. As a result, more than 60% of residents commute by bike or public transportation. This has significantly reduced air pollution and traffic congestion in the city.
Additionally, adopting this approach can have numerous benefits, such as promoting physical activity, reducing carbon emissions, and improving public health. Overall, I believe that cities with comprehensive public transportation systems should consider implementing policies that restrict the use of passenger cars in order to create a cleaner, more sustainable urban environment.
in the muscles.
Answer:
The functional unit of a muscle cell is known as a "sarcomere" which covers the distance between the two Z-lines.
The sarcomere consists of A-zone which contains both thick and thin filaments, H-zone which contains only thick filaments and I band which contains only thin filaments.
During muscle contraction, thick and thin myofibrils slide over each other due to which the distance between two z-line get reduced.The H and I zone gets shortened but A zone does not shorten but come close to other A- bands and disappears.
B. lichens
C the erosion of rock by weather
weather
D.volcanic eruptions
Factors such as the decomposition of organisms and the erosion of rock by weather contribute directly to soil formation except volcanic eruptions which produce rocks.
Soil is the topmost layer of the earth on which plant grow.
Soil is important to plants as it provides the plants with the nutrients they need to grow.
Soil can either be formed directly by the breaking down of large rock particles through plant, animals and weather conditions.
The formation ofsoil involves can be due to:
Therefore, all the above factors contribute directly to soil formation except volcanic eruptions which produce rocks.

Answer: D
Explanation:TOOK THE TEST
B) The cerebellum
C) The cerebrum
D) The basal ganglia
Answer:
D) The basal ganglia
Explanation:
Basal ganglia is located at the base of forebrain and the top of midbrain. It is involved in many functions because it is connected to many parts of the brain like thalamus and cerebral cortex. One of the functions of basal ganglia is to control the voluntary movements of the skeletal muscles.
Damage to basal ganglia can disturb the muscles causing involuntary movements, abnormal gait and increased muscle tone. For example, muscle tone is the tension in skeletal muscles caused due to minor involuntary contractions. Substantia nigra part of basal ganglia is responsible for controlling it. If it is damaged, muscle tone can increase which will cause unnecessary tension in skeletal muscles leading to uncontrolled movements.
Southern blot
agarose gel electrophoresis
polymerase chain reaction
Answer:
A. Polyacrylamide gel electrophoresis (PAGE)
Explanation:
Protein fragments of different size can be separated by gel electrophoresis method. Different proteins are made up of different number of amino acids and so the chain length vary i.e. the size of different proteins may vary. Also different proteins may have different charges due to difference in the type of amino acids present in them.
Generally for separating the protein fragments according to their size polyacrylamide gel is used. Foe this proteins are first given the heat treatment and treated with SDS for unfolding the protein. SDS is a detergent that imparts negative charge to protein. During electrophoresis, under the electric field the separation would be only due to size but not charge as all the proteins are treated with SDS and thus have same negative charge. This method is called SDS-PAGE. Under the electric field, small protein fragments will move fast through the pores compared to large fragments leading to their separation.
If two proteins are of same size then to separate them wither agarose gel electrophoresis is used or isoelectric focusing.
(B) protect coastlines from erosion.
(C) are found in shallow, nutrient poor, tropical waters.
(D) are the most diverse of all marine environments.
(E) All of these choices are correct
Answer:
(E) All of these choices are correct
Explanation:
Coral reefs are some of the most diverse ecosystems in the world. It is produced by Coral polyps and may occur as barrier, fringing, or atoll formations.
Coral reefs protect coastlines from storms and erosion, it is a rich source of job for local communities, and provides avenues for recreation. It is rich in food nutrients and can be used medicinally too.
It exhibits mutualism with photosynthetic algae called zooxanthellae. It supplies shelter and safety and materials needed by zooxanthellae for photosynthesis while it obtains nutrients and oxygen and waste removal mechanism from it.
