different types of cells in your body look and function differently. the basis for these differences is:
Answers
Different types of cells look and function differently, the basis for these differences is DIFFERENT PATTERNS of gene expression. This process (differential gene expression) leads to cell specialization.
Gene expression refers to the process by which the genetic information flows from a DNA sequence (i.e., a gene) to an mRNA molecule and finally to a protein.
In somatic (body) cells, the differential patterns of gene expression lead to the generation of different proteins and ultimately to different types of cells (cell phenotypes).
In consequence, cells are specialized to perform specific functions because different genes are being expressed.

Even though human proteins are made from only 20 different amino acids, there are thousands of differen proteins found in human cells. What allows for so much variation in the proteins?
Answers
Answer:
Amino acids are the basic building blocks of proteins, and they serve as the nitrogenous backbones for compounds like neurotransmitters and hormones. In chemistry, an amino acid is an organic compound that contains both an amino (-NH2) and carboxylic acid (-COOH) functional group, hence the name amino acid. Proteins are long chains or polymers of a specific type of amino acid known as an alpha-amino acid. Alpha-amino acids are unique because the amino and carboxylic acid functional groups are separated by only one carbon atom, which is usually a chiral carbon. In this article, we will solely focus on the alpha-amino acids that make up proteins

the spinal cord achieves the function of locomotion through __________.
Answers
Answer:
groups of neurons called central pattern generators
The spinal cord achieves the function of locomotion through groups of neurons called central pattern generators, hence option A is correct.
What are the groups of neurons in the spinal cord?Even when cut off from the brain and sensory inputs, "central pattern generators" (CPGs) nerve networks in the spinal cord can generate rhythmic motions like swimming, walking, and hopping.
In the absence of sensory or descending inputs that contain precise timing information, central pattern generators are neural networks that, when triggered, may create rhythmic motor patterns like as walking, breathing, flying, and swimming.
The spinal cord facilitates the movement of bodily components, accidents frequently result in people being unable to utilize certain body parts like the legs.
Therefore, the spinal cord achieves the function of locomotion through groups of neurons called central pattern generators, hence option A is correct.

Although we consume different foods, the parts are eventually used in cellular respiration. Does it matter if they originate from crickets or cows or candy bars?
Answers
Given what we know about biological processes, we can confirm that it does not in fact matter where the nutrients come from in terms of cellular respiration.
We consume food to provide the energy we need to function on a daily basis, for this, we may reach for an apple or opt for a candy bar. However, this is irrelevant on a cellular level. Cells do not eat the food the way that we consume them.
They use a process known as cellular respiration to change the food into energy to be used by cells. The most important of this process is the transformation of high-level sugars into simple sugars like glucose and other monosaccharides.
