What types of cells can our bodies no longer produced
lukranit [14]

Answer:

Yet, nerve cells in your brain, also called neurons, do not renew themselves. They do not divide at all. There are very few exceptions to this rule – only two special places in the brain can give birth to new neurons.

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.

Which term is used to describe what causes organisms to react to their environment? A. Stimulus B. Camouflage C. Parasites D. ho
Shalnov [3]
<span>A. Stimulus is the term used to describe what causes organisms to react to their environment. Stimulus is something that can provoke organisms to respond to the world around them. For example, if you put your hand on the stove, the stove is going to be the stimulus for you to get burned and move your hand from it because it will be to hot - that is going to be your reaction to the stimulus. Camouflage is a type of hiding mechanism, parasites are organisms, and homeostasis is equilibrium in an organism. </span>

why is it easier/ faster for our body to digest candy than pasta? candy contains disaccharides and thus contains more substrate
Zanzabum

Pasta contains starch and thus contains more substrate and needs more enzyme to digest.

<h3>What is starch ?</h3>

A polymeric carbohydrate called starch, also known as amylum, is made up of a lot of glucose units connected by glycosidic linkages. The majority of green plants synthesize this polysaccharide as a form of energy storage. It is the most prevalent type of carbohydrate consumed by people worldwide and is present in significant proportions in common foods like wheat, potatoes, maize (corn), rice, and cassava (manioc).

Pure starch is a powder that is white, odorless, tasteless, and insoluble in alcohol or cold water. It is made up of the branching amylopectin and the linear and helical amylose molecules. Starch typically comprises 20 to 25% amylose and 75 to 80% amylopectin by weight, depending on the plant. Animals store their energy in glycogen, which is a more intricately branched form of amylopectin.
