Melissa is studying a Gram-stained slide of curd bacteria. She sees many rod-shaped, violet-colored bacteria. What type of bacteria are they?

Answers

Answer 1
Answer:

Answer:

By the observation, the rod shape violet-colored bacteria could be a Gram-positive bacillus which is Lactobacillus spp.  in curd.

Explanation:

Gram-stain is a staining method to isolate and study the Gram-positive or Gram-negative bacteria with the help of the crystal violet dye. Crystal violet dye stains both Gram-positive and Gram-negative bacteria in purple stain. After decolorization, Gram-negative bacteria appears to be pink in color, however,Gram-positive bacteria remain purple.

According to bacteria structure, they term as bacillus (rod), strepto (clusters or threads) or Diplo (in pairs).

Thus, according to the observation, the rod shape violet colored bacteria are Gram-positive bacillus which is Lactobacillus spp. in curd.

Answer 2
Answer: Rod shaped = bacilli
Purple =Gram positive
The bacteria is Lactobacillus

Hi, There thank for posting your question here at Brainly, I hope the helps have a wonderful day
In biology, cell theory is the historic scientific theory, now universally accepted, that living organisms are made up of cells, that they are the basic structural/organizational unit of all organisms, and that all cells come from pre-existing cells. Cells are the basic unit of structure in all organisms and also the basic unit of reproduction.

The fight-or-flight response in humans is activated by epinephrine, a hormone secreted by the _____ glands.pituitary
thyroid
parathyroid
adrenal

Answers

The correct answer is adrenal

Adrenal glands are also called suprarenal glands which are located on the kidneys. They produce various hormones including epinephrine (adrenaline). Adrenaline is secreted when a person is under a fight-or-flight. This hormone quickly responds to the emergent situation or threat by increasing heart rate, slowing blood flow to muscle cells and changes other autonomic nervous functions, which gives energy and strength to fight any emergency.

The sympathetic nervous system. The hypothalamus, in close association with the limbic system of the brain. The two main chemicals invoved here are the neurotransmitter "norepinephrine" (noradrenaline) and the hormone "epinephrine" (adrenaline).

Answer: Line A is the enzyme, and Line B is the no enzyme

Explanation:

The reaction rate of a chemical reaction is greatly impacted by the presence of an enzyme. Enzymes are biological catalysts that speed up the chemical reaction by lowering the activation energy required for the reaction to occur. Without an enzyme, the reaction rate may be slow or even non-existent, whereas with an enzyme, the reaction rate can be significantly increased.

In order to compare the reaction rate with and without an enzyme, a graph can be plotted with time on the x-axis and the amount of product formed on the y-axis. The reaction without the enzyme would have a slower rate of product formation and would result in a lower slope on the graph. On the other hand, the reaction with the enzyme would have a sharper rate of product formation and would result in a steeper slope on the graph.

It is important to note that the reaction rate with an enzyme can only be increased up to a certain point, as the enzyme can become saturated with substrate molecules. At this point, the reaction rate will plateau and adding more substrate will not increase the rate of product formation.

Understanding the role of enzymes in chemical reactions is crucial in fields such as biochemistry and pharmacology, as many drugs and therapies work by targeting specific enzymes in the body. By manipulating the activity of enzymes, scientists can alter the rates of chemical reactions and ultimately impact physiological processes.
