Answer:
Explanation:
common warts are actually an infection in the top layer of skin, caused by viruses in the human papillomavirus, or HPV, family. When the virus invades this outer layer of skin, usually through a tiny scratch, it causes rapid growth of cells on the outer layer of skin – creating the wart
Answer:
The division of eukaryotic cell is done through various phase known as cell cycle.
Explanation:
The two basic phases of cell cycle is Interphase and Mitosis, that can be further divided into:
1) G2 Phase; G2 checkpoint ( Interphase stage)
2) Prometaphase (Mitotic Phase)
3) Anaphase (Mitotic Phase)
4) Telophase (Mitotic Phase)
5) cytokinesis (Mitotic Phase)
6) G1 Phase; G1 checkpoint ( Interphase stage)
After G1 phase there would be again S phase in which DNA replication occur.
Caverns most commonly form in limestone
Answer:
the answer is
Carbon dioxide concentrations are rising mostly because of the fossil fuels that people are burning for energy.Increasing the light intensity increases the rate of photosynthesis, until some other factor a limiting factor becomes in short supply. At very high light intensities,photosynthesis is slowed and then inhibited, but these light intensities do not occur in nature.
Explanation:
#1: Bacteria are like eukaryotic cells in that they have cytoplasm, ribosomes, and a plasma membrane. Features that distinguish a bacterial cell from a eukaryotic cell include the circular DNA of the nucleoid, the lack of membrane-bound organelles, the cell wall of peptidoglycan, and flagella. #2: Archaea have more complex RNA polymerases than Bacteria, similar to Eucarya. Unlike bacteria, archaea cell walls do not contain peptidoglycan. Archaea have different membrane lipid bonding from bacteria and eukarya. There are genetic differences. #10: Bacteria are classified into 5 groups according to their basic shapes: spherical (cocci), rod (bacilli), spiral (spirilla), comma (vibrios) or corkscrew (spirochaetes). They can exist as single cells, in pairs, chains or clusters. #12: Bacteria reproduce .In this process the bacterium, which is a single cell, divides into two identical daughter cells. Binary fission begins when the DNA of the bacterium divides into two (replicates). Each daughter cell is a clone of the parent cell. #13: Pathogenic bacteria are bacteria that can cause disease. ... One of the bacterial diseases with the highest disease burden is tuberculosis, caused by the bacterium Mycobacterium tuberculosis, which kills about 2 million people a year, mostly in sub-Saharan Africa. Infection with a pathogen does not necessarily lead to disease. Infection occurs when viruses, bacteria, or other microbes enter your body and begin to multiply.Pathogenic microbes challenge the immune system in many ways. Viruses make us sick by killing cells or disrupting cell function. #14: Antibiotics work by affecting things that bacterial cells have but human cells don't. For example, human cells do not have cell walls, while many types of bacteria do. The antibiotic penicillin works by keeping a bacterium from building a cell wall. HOPE I HELPED I Don’t NO #11
