Answer:
Different types of cells shapes effect the function of the cells. Muscle cells are shaped like they are because they have to perform a certain function to meet the critia of what the body is telling it what to do.
Explanation:
Skeletal muscle cells are located in a bundle of linear fibers. These are thin chains of the proteins actin and myosin that cause muscle contraction. The elongated shape of muscle cells allows contractile proteins to place themselves in an overlapping pattern that allows muscle flexion.
Gene is a sequence of DNA that codes for a specific, detectable product, such as a protein.

What is a Gene?</h3>
This is defined as the basic physical and functional unit of heredity and occupy a fixed position on a chromosome.
It is also the sequence of DNA that codes for a specific, detectable product, such as a protein or RNA.

Answer:A
Explanation:The anatomy and behavior of that animal's immediate ancestor..
Answer:
a. Bands at 1kb, 6kb and 8kb
Explanation:
The EcoRI and BamHI are the restriction enzymes which cut the DNA sequence especially a plasmid at specific sites called the restriction sites.
The restriction enzymes produces bands of specific length therefore these restriction enzymes are used to estimate the approximate length of the DNA.
In the given question, the
1. EcoRI- produces two strands of 7 kb and 8 kb
2. BamHI- produces two strands of 1kb and 14kb
This shows that the length of DNA sequence is 15kb
But when the DNA strand are digested with both the enzymes simultaneously then it will produce three bands as:
i) 14 kb can be broken down in 2 bands of 6 kb and 8 kb
ii) 1 kb band is already produced by the Bam HI.
This shows that 1+6+8= 15 kb
Thus, Option-A is correct.
