Answer:
Figures attatched
Explanation:
1. Restriction enzymes cut the DNA in specific places of a specific sequence. Each restriction enzyme has different sequences of recognition.
2. Palindromic sequences are sequences that can be read the same in both senses (3' and 5'), for that reason restriction enzymes can cut both DNA strands
Now, for the first image: if a molecule has 5 restriction sites that are known for a single restriction enzyme, the enzyme will cut the DNA 5 times. If you see the image, the number of fragments is the number of restriction sites +1. In this case, it is 5+1=6 DNA fragments.
In the case of two different palindromic sequences, two different restriction enzymes recognize different sequence. If just one enzyme is present, the only cutting site will be the one that has the palindromic sequence recognizable. So, the number of fragments will be 1+1=2 DNA fragments (figure 2)
Answer:
a) Myelinated nerve fibres
b) The white matter
c) gray matter
Explanation:
The three main parts of cerebral hemispheres are
a) Myelinated nerve fibers
b) The white matter
c) Gray matter
The nerve fibers of the white matter are responsible for connecting the functional parts of cerebral cortex while the gray matter is further divided into four surface folds/lobes with each lobe associated with a specific activity. Such as frontal lobe take cares of motor activity and speech, parietal lobe is responsible for touch and position sensation, occipital lobe for vision and temporal lobe for hearing.
ATP molecule functions as the power source for a cell. Sometimes it is compared to a battery, which is a pretty fair analogy, but it is more mobile and flexible in its functions than a battery is.
The number of producers is greater then the number of consumers , primary consumers is greater then the number of secondary consumers and the secondary consumers is greater then the number of tertiary consumer
