Maltase, for example, acts only on maltose. Students should know that some questions are outside the realm of science because they deal with phenomena that are not scientifically testable.

You can think of glucose as a kind of cellular piece of coal: Protein synthesis Main article: The substrate molecule fits into the active site of the enzyme like a key into a lock.

Physics Notes for Class 10th

The student understands how human activities impact aquatic environments. Creation of Man Allah also sys in Quran: There are several types of organelles in a cell.

Form 4 Biology

The present animals are advanced forms of the past animals who achieved this form after passing through many changes. When ethanol levels rise to about 12 percent, the yeast dies.

These are the procedures and techniques used to store and preserve information as well as specimens of various plants and animals. He made antiseptic medicines like Iodine and Carbolic acid. It is the storehouse of collected plant specimens. This allowed condensation and heavy rains, which caused formation of oceans.

The earth had high temperature and radiation and had frequent and abundant discharges. Various models of the spread of infections have been proposed and analyzed, and provide important results that may be applied to health policy decisions. Understanding these interactions and cycles over time has implications for life on Earth.

Students shall be awarded one credit for successful completion of this course.

CBSE Class 12 Biology Revision Notes Chapter 1 - Reproduction in Organism

All cells except red blood cells which lack a cell nucleus and most organelles to accommodate maximum space for hemoglobin possess DNAthe hereditary material of genesand RNAcontaining the information necessary to build various proteins such as enzymesthe cell's primary machinery.

Eukaryotic genetic material is divided into different, [3] linear molecules called chromosomes inside a discrete nucleus, usually with additional genetic material in some organelles like mitochondria and chloroplasts see endosymbiotic theory. Some cells, most notably Amoebahave contractile vacuoles, which can pump water out of the cell if there is too much water.

The active site loses its shape and the enzyme-substrate complex can no longer be formed. According to some people, insects are produced from dewdrops, rats from debris, frogs from mud, and maggots from putrefied meat. The student can quantify the changes that occur during chemical reactions.

They found some animals to be developed from non living matter. This means that for every glucose molecule that enters glycolysis, the Krebs cycle runs twice.

Newly synthesized proteins black are often further modified, such as by binding to an effector molecule orangeto become fully active. They are long and thick thread-like appendages, protein in nature. Enzymes formed and retained in the cell are known as intracellular enzymes, and occur in the cytoplasm, organelles or the nucleus.

The student knows the reasons for the seasons. A analyze, evaluate, and critique scientific explanations by using empirical evidence, logical reasoning, and experimental and observational testing, so as to encourage critical thinking by the student; B communicate and apply scientific information extracted from various sources such as current events, published journal articles, and marketing materials; C draw inferences based on data related to promotional materials for products and services; D evaluate the impact of research on scientific thought, society, and the environment; E describe the connection between chemistry and future careers; and F describe the history of chemistry and contributions of scientists.


The student knows that Earth's global ocean stores solar energy and is a major driving force for weather and climate through complex atmospheric interactions.
