Answer:
Option C, 66%
Explanation:
Zoonotic pathogens are the ones which are transmitted from animals to human beings.
As per the study of world health organisation, nearly 61% of human diseases caused by pathogens are due to Zoonotic pathogens. This percentage has increased from last ten decades to 75%.
As per Center for Disease Control and prevention, more than 50% pathogens are Zoonotic pathogens
These pathogens can enter human being through various medium such as air, water, contaminated food, hand or mouth contact etc.
Some common examples of disease caused by zoonotic pathogens are -
Malaria, dengu, Typhoid etc.
Hence, option C is correct
Answer:
E. lack peptidoglycan, are the smallest free-living organisms AND have sterols in their membranes.
Explanation:
Mycoplasmas are also called pleuropneumonia-like organisms (PPLO) are the smallest free-living, prokaryotic organisms. They do not have a cell wall and is bounded by a plasma membrane which contains sterol.
Since cell wall is absent in them, they lack peptidoglycan. These are present in animals, plants, insects, soil and sewage. They grow better in the aerobic environment but can also live as facultative anaerobes.
Mycoplasma cause infection, affects cell metabolism, gene expression.
Answer:
B) embryology
Explanation:
Embryology by definition is the branch of biology and medicine concerned with the study of embryos and their development. All the other answer choices would not fit what your question is looking for. A botanist is someone who studies plants. An obstetrics is someone who studies childbirth. And internal medicine is completely out of the question.
b. Phospholipids
c. Glycogen
d. Glucagon
Answer:
C. Glycogen
Explanation:
When the food made of carbohydrates is broken in the organism, it creates glucose, which is a type of sugar that the body uses as a form of energy. The amount that is not used gets stored in various tissues of the body, but the places where the glycogen is stored in larger amounts are the liver and skeletal muscle.
Answer:
Glycogen
Explanation:
Glucose is used primarily as a source of energy and as such it has to go inside the cell. Excess glucose that is not immediately needed as a source of energy is combined into long strands of clucose units called glycogen and it is stored in the liver and skeletal muscle tissue. Glycogen is later broken dowin into its constituent glucose units and used as a source of energy when needed.
Answer:
Extinction
Explanation:
Answer:
extinction if they are hunted so much
Answer:
The correct answer is ecological succession.
Explanation:
For the growth and development of an ecosystem, the phenomenon of ecological succession plays an essential role. A slow procedure by which the ecosystems modify and develop with time is termed as the ecological succession. There are prime two kinds of succession, that is, primary succession and secondary succession.
The phenomenon of ecological succession helps in the colonization of the novel areas, and in the recolonization of the destructed ecosystems, this helps the species to get amend with the modifications taking place in the surroundings and helps them to thrive. The given case is an illustration of ecological succession as the flowing of lava creates barren land, which further helps in the establishment of the pioneer plants. These pioneer species of plants helps in the development of a new ecosystem.
Answer:
The major role of bacteria in the ecosystem is the decomposition of organic matters.
Explanation:
The breakdown of these organisms and the release of the nutrients back to the environment is what called decomposition. These bacteria found in our ecosystem convert gaseous substances like nitrogen into nitrates or nitrites as a part of their metabolism and the product resulting from this process will be released to the environment.
Answer: Decomposition of organic matter
Explanation:
Decomposition is a biological process that involve the breakdown of complex organic matter into smaller molecules to release minerals forms of nutrients and carbon dioxide. Bacteria help in decomposition by feeding on them and release nutrients. There are two forms of decomposition, the aerobic I.e it occur in the presence of oxygen by the activities of aerobic bacteria or anaerobic decomposition which occur in the absence of oxygen by the activities of anaerobic bacteria.
