Answer: alternating dark and light bandsof protein filaments
Skeletal muscle fibers contain striations that can be described as alternating dark and light bands of protein filaments. Actin, tropomyosin, and troponin are among the protein filaments. The dark bands are the so-called A bands. Alternating light bands are referred to as I bands.
Answer:
False
Explanation:
There is only one legitimate interpretation of the meaning of red shift data. The red shifts of quasars and connected galaxies can be different by billions of light-years. The discovery of quantized red shift observed in related galaxies has no relation to the Big Bang model.
Answer:
See the answer below
Explanation:
<em>The problem with grouping organisms together taxonomically based on their physical traits is that organisms that not genetically or evolutionally similar would be grouped together. Grouping would be based entirely on superficial similarities instead of combining different features such as genetics, nutrition, the complexity of bodies, etc.</em>
Based on physical traits, for example, all flying organisms will be grouped together. Birds, flying insects, bats, etc. would be grouped together, whereas, they are quite different from one another when it comes to the complexity of bodies and other features. Even though some insects have wings and can fly like birds, insects have exoskeletons and birds do not, the body of birds is more complex than that of insects, and evolutionally, birds are more advanced than insects.
Hence, grouping organisms based on their physical traits only would be too superficial and not reflect the true relationships between organisms.
Answer: 6N and it’s moving up
Explaining: Net force is when you add or subtract the amount of force that is being Applied to a object- in this case it’s being applied on opposite sides this means we subtract from the bigger force
12N - 6N = 6N
An established conditioned stimulus is paired with a new neutral stimulus in: higher-order conditioning.
Classical conditioning refer to a learning process that involves the repeated pairing of two (2) stimuli:
Basically, classical conditioning is a learning procedure which helps psychologists in understanding when a neutral stimulus is paired with a conditioned response or a neutral stimulus and an unconditional stimulus.
Similarly, a higher-order conditioning involves pairing an established conditioned stimulus with a new neutral (the second-order) stimulus, in order to make the new stimulus elicit (bring forth) the conditioned response, without presenting the initial conditioned stimulus.
