Concept Checks 1.1
1. For each biological level in Figure 1.3, write a sentence that includes the next “lower” level. Example: “A community consists of populations of the carious species inhabiting a specific area. ❖ The biosphere consists of all the environments that take place on Earth, including most regions of land, most bodies of water, as well as the ecosystems that combined to help make up the biosphere. ❖ An ecosystem consists of all the living things in a particular area—abiotic and biotic—where the entire array of organisms that inhabit are called a community. ❖ A community includes many kinds of trees and plants, as well as animals. All of the individuals of the same …show more content…
species living together create a population. ❖ A population is made up of a group of organisms—which are individual living things. ❖ All organisms consist of organs and the organ systems such as the digestive system, the tongue, the stomach, and the intestines.
❖ Organs are made of up a group of tissues that work together. At this level, tissues require the use of a microscope. ❖ To the next level, we have that each kind of tissue is a group of similar cells working together. ❖ Cells are the unit structure and function of all living things; though, even at the smallest level, cells contain numerous green structures called chloroplasts—known as organelles. ❖ Organelles—Chloroplasts being an example—are made up of teeny tiny chemical structures called molecules. ❖ Finally, molecules are composed of two or more small chemical units called atoms.
2. What are the relationships between these three genetic terms: DNA, genes, and chromosomes? Between these three terms, DNA, or deoxyribonucleic acid, are what partly make the chromosomes. Chromosomes structures are what are within cells. Lastly, genes are the units of inheritance that transmit information from parents to offspring in which DNA is the substance.
3. Explain why, at the cellular level, plants have more in common with animals than they do with
bacteria. First off, Plants are eukaryotic, meaning they have a true nucleus and membrane-formed organelles. Plants and animals have multiple linear chromosomes while bacteria have a single chromosome. Considering they are eukaryotic they both share the characteristics of having a cell membrane, cyotplasm, endoplasmic reticulum, golgi body, mitochondrion, ribosomes, vacuole, and a nucleus.
Concept Checks 1.2
1. Apply the principal of emergent properties to explain the relationship of a sentence to the alphabet of letters from which that sentence is constructed. By using letters from the alphabet, they represent sounds. By putting those ‘sounds’ in the right combinations, letters form words that have a meaning. 2. How does high-throughput technology complement bioinformatics? High-throughput technology are the new methods that can analyze biological materials and chemicals to be quickly and efficiently screened to view anyone more in detail, complimenting the bioinformatics to look at DNA sequences and protein interactions. 3. When you flush a toilet, water begins to fill the tank and lift a float attached to a lever. When the water level reaches a certain height, the lever shuts the water valve and prevents the tank from overflowing. What type of regulatory mechanism is at work in this nonliving system? During this process, the regulatory mechanism of negative feedback in which the end product of the process of the water reaching to a certain height slows the process down to prevent from overflowing.
