The reporter may misunderstand what is printed 9. Which types of URL's on the internet are considered more reliable when trying to find a website with scientific information? URL’s that end in .edu, .gov, and .org. Which types of URL's should you carefully question and verify? URL’s that end in .com or .net. Why? Because quite a bit of scientific info on the Inet is intended to entice people. 10. What is anecdotal data? Testimonies by individuals rather than results from a controlled, clinical study which isn’t reliable. Why is it considered unreliable supporting scientific information? Because it’s subjective. 11. Why is correlation data (data showing that two events occurred at the same time) not necessarily meaningful? Because one factor might not be the cause of the other. 12. Briefly define the following: Matter is anything that takes up space. Element is any substance that can’t be broken down into substances with different properties. Atom is the smallest part of an element that displays the properties of the element. 13. What are the subatomic particles and what is the electrical charge of each? Protons (positively charged), Neutrons (electrically neutral), both found in the Nucleus of the atom & Electrons (negatively charged). Where in the atom is each of these particles found? In the orbital (Electrons) 14. Which two types of bonds join atoms into
2. Matter, anything that occupies space and has mass, and energy, the ability to do work or to cause a change, are the two components of the physical world.
They must be eukaryotic, meaning they have nucleus, and in the domain Eukarya. In the Linnaean classification this could be in the kingdom Protista like a paramecium. Another Linnaean classification of this could be in kingdom Animalia, since they are heterotrophs and their cells contain a nucleus. They could be grouped as predators, since the organism is engulfing another organism. They could also be grouped based on their locomotion. They could have cilia, legs, or even flagella.
Coelomates have an enclosed body cavity, which means advance muscle structure, enhanced locomotor capabilities, and more structural integrity.
6. What kingdom are algae classified? The classification of algae is not yet settled, however, there are different divisions of kingdoms. Chlorophyta (Green Algae), Kingdom Rhodophyta (Red Algae), Halophyte (Brown Algae), Chrysophyta (Golden Algae, Yellow-Green Algae, and Diatoms) What domain? Eucaryotes-eucaryotic photosynthesizers (plants) Algae are classified by their photosynthetic absorption spectra.
The purpose of this study is to identify four unknown organisms. The unknown organisms have been assigned randomly to six-research groups by Professor Hoffman. Each research group was provided two eukaryotes and two prokaryotes. The unknown organisms will fall into the following classifications: bacteria, algae, fungi, or protozoans. All living organisms are organized into one of three domains of life, Bacteria, Archaea, and Eukarya.
The atom is a unit of matter, the smallest unit of an element, consisting of a dense, central, positively charged nucleus surrounded by a system of electrons, equal in number to the number of nuclear protons. It consists of a core nucleus surrounded by negatively charged electrons. Inside the atom nucleus contains a mixture of positively charged protons, and electrically neutral neutrons. All electrons bind to the nucleus through an electromagnetic force. A ground of electrons bound together form individual molecules. An atom with an equal number of protons and electrons will hold a neutral charge. An ion has either a positive or negative charge because of a lack of electrons or an electron excess. The number of protons determines the
As early as 400 BCE atoms were believed to be the building blocks of all matter. The atom is made up of three subatomic particles protons (p+) , neutrons and electrons ( e-). Protons have a positive charge and can be found in the nucleus along with the neutrons who have no charge. Protons, along with electrons, tell you the atomic number of any given element. A positron is the opposite of an electron and contains the same mass and spin of an electron but they have a positive charge. The sum of the number of protons and neutrons equals the mass number. The mass number connects matter to it’s antimatter, they are equivalent in value while the charges are opposite. This attraction cause the corresponding matter particles to annihilate each other.
An atom is the smallest particle of a chemical element that can exist. Atoms consist of negatively-charged electrons orbiting a positive nucleus. Inside the nucleus are positively-charged proton/s and electrically neutral neutrons.
Evaluate the merits and limitations of different models of the atom in relation to relative size, charge, and position of protons, neutrons, and electrons in the atom.
There is an enormous variety of life on our planet Earth ranging from simple cell bacteria to complex multicellular animals. Animals are creatures in the kingdom Animilia, one of the kingdoms in Whitakers 5 kingdom system. Their bodies consist of 555tanimal eukaryotic cells. Meaning their cell or cells contain a nucleus, are surrounded by a cell membrane (phospholipid bilayer) and can self-reproduce in a free medium. However, not all animals are anatomically the same. They have evolutionized, inside and out, from the ancestral protozoa all the way to the most complex animals chordates. As the animals evolved, cells became tissue, tissues became organs,
The term ‘eukaryote’ encompasses most of the visible species on the planet. A eukaryotic cell is one who's genetic material and organelles are bound by membranes, as opposed to a prokaryote who’s nucleoid and organelles are not membrane bound and sit within the cell membrane in the protoplasm - this grouping is considered the most fundamental classifications of organisms.
Towards the end of the class, the instructor will ask student some basic questions about the science or physics that is around them. Instruction explain some concepts to student, by saying that anything that has mass and can occupied space is called matter. Atoms are the main components that make up matters. Name the particles that are in different form in an atoms; answer to this question is electrons, protons and neutrons. Where protons and neutrons is find in an atom? Answer: proton can be find in the nucleus,
Analysis of Data: Our data did not support our hypothesis, and though that does not necessarily correlate to decreased importance of data, ours could have had several sources of error. The primary source of error would be human,
There are two basic categories of that all cells fall under. They are prokaryotic cells and eukaryotic cells. Prokaryotic cells are single-celled organisms that include bacteria and archaea.
Eukaryotes come in two grades of organization: single-celled (protists) and multicellular (plants, animals, and fungi). The world today is full of complex multicellular plants and animals: how, why, and when did they evolve from protists?
