A saprophyte is a fungi or bacteria that lives on the dead organic matter.
Explanation:
The saprophytes get food from dead organic matter. They are heterotropes. Rhizopus, aspergillus, mushrooms are the examples of saprotrophs.
The main role of saprophytes are they break the dead and decaying organic matter into small substances that can be taken and recycled by plants.
Only a small portion of species of fungi causes disease in plants and animals.
Mushrooms do not contain chlorophyll and are considered as saprophytes.
Notochord! this answer is correct.
Answer:
Option D
Explanation:
(the gene for the disease has incomplete penetrance. the gene for the disease has limited expressivity. the disease is polygenic) - all these are examples of non-mendelian inheritance which include incomplete penetrance, polygenic inheritance etc. These do not follow the mendelian pattern of inheritance.
(the gene for the disease is recessive.)- this shows the mendelian pattern of inheritance... Dominant and recessive characteristics are examples that show Mendelian inheritance.
The viral component that is responsible for inducing a host cell to take in an influenza virus by endocytosis would be hemagglutinin. It is a glycoprotein that can be found in the surfaces of an influenza virus and is essential to its entry to hosts. It is the substance that is responsible for allowing the virus to bind to cells especially cells in the respiratory tract. It also causes the RBC or the red blood cells to agglutinate or clump together. The hemagglutinin is cylindrical in shape and is 13.5 nm in length. It has 18 different antigens wherein they are named H1 to H18.
