Kyle Eagle Human Biology BIO 108 G Final Exam Essays FINAL EXAM ESSAY 1). A cell is in the process of transcription. The single strand of DNA that is being copied has the sequence ATC GCA GGA TGC. Indicate the mRNA strand that will be synthesized from this strand‚ listing the correct sequence of bases. Describe why this step is important in the process of producing proteins. Explain how gene expression is regulated. The mRNA coding sequence can be described as units of three nucleotides

down food into particles that can be used for nourishment. The stomach is not the only organ involved in the digestion process. A series of organs comprise the human digestive tract‚ including the mouth‚ esophagus‚ stomach‚ small intestines‚ liver and large intestine. Each organ in the digestive tract plays an integral part in the digestive process. The food enters the mouth‚ where it is masticated and prepped for digestion. The mouth is comprised of multiple features that contribute to the beginning

The cardiovascular system is made up of the heart and blood vessels‚ which are divided into arteries‚ veins and capillaries. The blood delivers nutrients and oxygen to the cells in the body. The arteries carry blood away from the heart and the veins carry it back to the heart. Capillaries are found in the muscles and the lungs‚ they have valves to stop the blood flowing backwards and this is also where gaseous exchange takes place. The heart works as a pump that pushes blood to the organs‚ tissues

Animals have heterotrophic cells; hence‚ they live off nutrients of other species by eating. Most plants have autotrophic cells‚ which allow them to generate their own food with photosynthesis. 4) Explain the following statement: ‘All living things depend on plants’. As animals are heterotrophs‚ they need to eat other species to survive. If mammals only depended on other mammals‚ there

The innate immune system is referred to as the first line in host defense against invading pathogens and preserve host integrity [1]. Of them the innate immune cells have sensors such as macrophages and dendritic cells (DCs) detect molecular components of foreign microorgan¬isms known as pathogen-associated molecule patterns (PAMPs) through PRRs. Its highly developed ability to recognize microbial patterns and host derived danger signals relies on so-called PRRs‚ especially on the TLRs‚ RLRs and
