How does the structure of a brain cell related to its function?
lesya [120]

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.

Suppose that the plasma membrane around a eukaryotic flagellum is opened to reveal the axoneme inside. the radial spokes connect
mash [69]

The flagella of the eukaryotes is composed of the doublet microtubules. The central bundle of these microtubules is known as the anoxeme. In an axoneme, a single pair of the singlet micortubules is surrounded by the nine doublet microtubules. When the plasma membrane of the flagellum is opened to expose the axoneme, and the radial spokes are broken, it will lead to the elongation of the axoneme,

Babies with very low or very high birth weight are less likely to survive. Observe a graph of the data.
vaieri [72.5K]

I need to see said graph but to my understanding most under weight babies are born early so their body is not fully developed but as an slightly over sized baby myself the biggest problem was for my mom because she had to have a c section because I was too big to come out the normal way

by the way c section stands for Cesarean section

hope all this helps
