In which groups of microorganisms it is found? Bacteria are living organisms that produce energy and are capable of independent reproduction. Activators are positive regulators because their presence is required for the regulated enzyme to be made while repressors act as negative regulators because their regulatory activity is to prevent the synthesis of proteins. Land plants contain a b+ of chlorophyll a and b molecules. Granulocyte: Granulocytes have granules in their cytoplasm and their nucleus is Characteristically 2-4 lobed. Protists are a diverse paraphletic group, most are unicellular but some are multicellular or form aggregations called colonies. I will record results measured by the graduated intervals on the pipette attached to the respirometer.
It is sometimes reasonable to assume that highly conserved protein like globin and cytochorme c can be used as a molecular clock to measure how long the species have been diverging from each other. Ans: The regulatory genes that produce a regulator protein controls induction i. Therefore, the number of days the peas have been germinating will be my experimental variable. The results from that study are shown in the following graph. A cruciform structure in which of two strands each forms hairpins by intra-strand hydrogen bonding. Examples of eukaryotic organisms include , , and protists ex.
However, the organization of your ideas is paramount for earning a good grade. Identify, isolate, and test one experimental variable in your experiment. You can on this or any other topic at 123HelpMe. Which one is your favorite and why? Ans: It is because more than one codon can code for the same amino acid. These caecae reach near almost every cell of the body.
Plants are typically polyploid, whereas mammals tend to be diploid. What is the importance of wobble and degeneracy? Searching for the notes of short questions solved of class 11 biology in english? A cistron may also be defined as the functional unit of genetic inheritance a segment of genetic nucleic acid which codes for a specific polypeptide chain. The mutant alleles may differ from the wild type, e. Identify any variables that you must control, and explain the apparatus that you will use to measure the cellular respiration. Describe what is going on with the reproduction of the Angler fish. Answer : Guttation or exudation is loss of liquid water through water secreting glands called hydathodes.
The dolphin is actually a sea mammal. The types of creatures that live in these regions provide insights into the early forms of life on Earth, thus aiding evolutionists. While plants are capable of generating their own food through , animals must obtain nutrition through ingestion or absorption. During this time you should read the questions and create short outlines to guide your responses. Hydrothermal vents support an immense biomass under very high temperatures.
Here antibodies attach to the surface of bacteria and speed up their phagocytosis, or combine with them neutralise toxins produced by micro-organisms, by producing antitoxins. Here we have shared the 1st Year Biology Important Short Questions All Chapters - 11th Bio Notes pdf. In almost every culture, women usually out live men. The arabinose operon C protein which is an activator causes making of arabinose enzymes on binding to the inducer arabinose. B Key points to include: labels on each axis, regular intervals on the graph, a specific title on the graph, points plotted on the graph, and a line connecting the appropriate points.
I will use an apparatus called a respirometer to measure the amount of O 2 consumed. All newly synthesized bacterial proteins start initiate with formylmethionine may be abbreviated as fmet. While several factors can influence the life expectancy differences between men and women, genetic makeup is considered to be the major reason women live longer than men. Use of either or, neither nor, not only playlist 24. Use of Do, Does Playlist 6.
Be sure to distinguish between the relevant information and the extraneous information. Fingerprints are unique, even among identical twins. It is also a highly social and curious animal. I will be able to measure the amount of water drawn into the pipette by comparing where the water mark begins and where it ends. . Without grammar speak sentences Playlist 13. If this plasmolysed cell is placed in distilled water which has highest water potential the water molecules would move from distilled water through differentially permeable cell membrane into the cell, and the cell would come to its original form.
They are formed while we are in our mother's womb and are influenced by several factors. These plasma cell synthesis and liberate antibodies into the blood plasma and tissue fluid. Some other mutator genes in E. Procedure: I will place 20 peas that have been germinating for one day in one respirometer and 20 peas that have been germinating for three days in another respirometer. Alternatively, you can simply write a short phrase above each line for identification. Less water lost under mist; because reduced water potential gradient. Viruses must rely on other organisms in order to reproduce because they do not possess the organelles needed to replicate.
What about hydrothermal vents may provide insight into the evolution of life on earth. If you have the chance to take a trip in Alvin, would you do it? In a long-term project studying the interactions of several species of animals on an isolated island, scientists counted the number of individuals of each species visiting a site on the island over the course of several days, every summer for 100 years. Humoral Immune response: In humoral immune response B- lymphocytes recognize antigen and form plasma cell clone. When we detect a sound, sound waves travel to our and the sound energy is converted to nerve impulses. Anueploidy refers to an invorrect chromosomes number in the cells e.
