Answer:
<em>Agrobacterium</em> <em>tumefaciens</em> is a gram negative bacteria that is responsible for tumor formation in the different parts of plant body.
Explanation:
It causes crown-gall disease in plant body by transferring it's DNA into the plant body which include Ti plasmid.
There are 3 types of bacteria that form tumor in different plant ares.
<em>Agrobacterium rhizogenes</em>,<em> Agrobacterium tumefaciens</em> strains contain either Ti or Ri plasmid but <em>Agrobacterium vitis</em> contain only Ti plasmid which are virulent.
The transfer of T-DNA takes place into the body of host cells and then the DNA is expressed into the body of the host and thus forming gall or tumor.
Answer:
There are many questions that can be answered by science but I will provide some examples below.
Explanation:
Science involves many areas of study, <u>from biology and chemistry to physics and neuroscience</u>. Generating questions and providing answers are the most important steps in science as this process has allowed thousands of scientists to develop new drugs to treat previously-mortal diseases, to protect endangered species, to prevent population declines, to understand the behavior of fauna, among many other remarkable outcomes and discoveries.
In this answer, I will focus on some questions belonging to the life sciences areas that can be answered by science:
Biology
<em>How does climatic phenomena, such as El Niño and La Niña, affect the migration of whales?</em>
<em />
Neuroscience (humans)
<em>Is schizophrenia hereditable?</em>
<em />
Behavioral Ecology
<em>Does climate change affect the capability of cuttlefish to camouflage?</em>
Neuroscience (Animals)
<em>Are killer whales capable of problem-solving?</em>
<em />
Ecology
<em>How does the reduction of apex predator populations (terciary consumers) affect the population of secondary consumers?</em>
<em />
Conservation Biology
<em>Why do increased temperatures lead to coral bleaching? What is the mechanism and how can it be controlled?</em>
<em />
Animal Behavior
<em>What is the mechanism that Ophiocordyceps unilateralis (Zombie fungus) uses to manipulate ants for its own disperal?</em>
<em />
Parasitology
<em>Does the parasite Toxoplasma gondii induce erratic behaviors in humans?</em>
Enzymes are biological catalysts. Catalysts work by lowering the amount of energy required to set off a chemical reaction.
Explanation: some cells are specialized to do certain stuff. Like the breaking down of glucose wouldn't happen in the cells found in your leg.
