Solution:
Structure dictates function. Ribosomes provide another good example of structure determining function. These small cellular components are made of protein and ribosomal RNA (RNA).Their main function is to translate messenger RNA, or mRNA, into strings of amino acids called proteins.
The structure and shape of each type of human cell depends on what function it will perform in the body. For example, red blood cells (RBCs) are very small, flat discs, which allows them to easily fit through narrow capillaries and around sharp corners in the circulatory system to deliver oxygen throughout the body.
Neurons carry messages from the brain and spinal cord to the rest of the body, using electrical signals down their lengths and chemical signals between neurons. Since electrical signals travel much faster than chemical signals, neurons are long and thin to minimize the number of slower chemical signals that would be required between links in a chain of many shorter neurons.
The elongated shape of muscle cells allows the contraction proteins to line up in an overlapping pattern that makes muscle flexing possible.
And human sperm cells’ structures allow them to “swim” long distances to reach an egg for fertilization. They do this by using flagella, their long whip-like tails, and also by being very small, carrying little more than the DNA for a potential zygote.
This is the required answer.
Answer:
While crenation occurs in animals cells, cells that have a cell wall cannot shrink and change shape when placed in a hypertonic solution. ... Instead, the protoplasm shrinks, leaving gaps between the cell wall and cell membrane. The cell loses turgor pressure and becomes flaccid.

Answer:Dna template- 5' ACTCCTGAA 3'
3' TGAGGACTT 5' complementary base
Explanation: Dna consist of a double stranded helix structure. Replication occurs to make extra copies of DNA strand. The DNA strand use to make extra copy is the template strand while the mirror image is the complementary base.
Replication occurs in 5' to 3' direction.
For complementary base in DNA Adenine complement thyamine
Cytosine complement Guanine
i.e A-T
C-G
Hence the complementary base in 3'-5' direction is 3' TGAGGACTT 5'
Your answer will be False!
