Diagnosis of Gardnerella vaginitis is made by the appearance of _____. anaerobes in a microscope slide clue cells epithelial cells endotoxin
Answer: The correct answer to the question is option B
CLUE CELLS.
Explanation: Gardnerella vaginitis is also known as bacteria vaginosis.
It is a disease of the reproductive system that affects mostly women of child bearing age, bacteria vaginosis occurs when there is a shift or change in the normal balance of bacteria found in the Vagina,this change in bacteria balance results in infection.
Symptoms of includes vaginal itching, abnormal vaginal discharge and odour.
When Gardnerella vaginitis is diagnosed,the following are being noted;
Clue cells; this involve coating vaginal skin cells with bacteria,clue cells are visible on microscopic exam of vaginal fluid.
When vaginal fluid is tested and the PH shows low acidity( a PH greater than 4.5 precisely).
(WHIFF TEST)When there is a fishy odour upon combination of vaginal discharge with a drop of magnesium hydroxide. A glass slide is used for this test.

Which of the following domains contains organisms that are adapted to life in harsh environments?
A) domain Eukarya
B) domain Archaea
C) domain Plantae
D) domain Bacteria
E) domain Animalia
Answer:
B
Explanation:
Many species in Archaea actually require extreme temperatures and conditions to grow
The domain that contains organisms that are adapted to live in harsh environments is the domain Archaea. The correct option is B).
What is the domain Archaea?Any single-celled prokaryotic organism without a definite nucleus is referred to as an archaea, and they differ from bacteria in a number of important ways at the molecular level.
Archaea have membranes that are formed of branching hydrocarbon chains, many of which also contain rings, connected to glycerol via ether bonds, as opposed to bacteria and eukaryotes.
The microorganisms in the archaea domain are not typical of natural habitats. Instead, they can be found in severe and extreme environments like hot springs, salty environments, acidic conditions, etc.
Therefore, the correct option is B) domain Archaea.

Why plant cell does not burst even if placed constantly in hypotonic solution?
Answer:
Explanation:
It's simply law of osmosis.
In osmosis solvent particles move from lower solute concentration to higher solute concentration until both the solution acquire the same concentration. So when a plant cell is kept in hypertonic solution (having more solute concentration), the solvent particles move outside the cell causing it to shrink, which is also known as plasmolysis of cell.
When a plant cell is kept in hypotonic solution (having less solute concentration), the solvent particles move inside the cell causing it to swell up which is also known as deplasmolysis. But due to the presence of cell wall, plant cell can not burst. Cell wall is a very stratchable boundary made up of cellulose mainly which makes the plant cell non-collapsable (but animal cells can burst in hypotonic solution due to absence of cell wall)
Have a great day!!!!!!!!

Some flowering plants are pollinated by honeybees. At some time in the past, honeybees evolved the ability to see ultraviolet radiation. Some flowers have evolved to produce ultraviolet markers on their petals that direct honeybees to the reproductive parts of the flower. What is this an example of?
Answer:
Coevolution
Explanation:
Just took the test and got it right
hopefully this helps you :)
pls mark me as as brainlest
The example of flowers evolving to produce ultraviolet markers on their petal in response to the ability to see ultraviolet radiation in honeybees is that of coevolution.
According to a definition, coevolution refers to reciprocal changes in 2 or more living organisms that are involved in some forms of interactions.
In other words, it is the development of certain characteristics by one organism in response to characteristics developed by another based on the fact that the two organisms interact in some ways.
In the illustration, some flowering plants depend on honeybees for pollination. Thus, as the honeybees developed the ability to see ultraviolet radiation, flowers had to evolve ultraviolet markers so as to keep guiding the honeybees to them and keep the relationship going.

Explanation:
A student wants to investigate how adding fertilizer affects the growth of flowering plants. She gathers 10 identical flowering plants and divides them into two groups of five plants. One group receives the same amount of fertilizer at the same time each day for four weeks. The other group does not receive fertilizer. All plants in both groups are kept at the same temperature and given the same amount of water and light every day for four weeks. The growth of the plants after four weeks what would be the independent variable , dependent variable, hypothesis, and 3 controls no
Independent Variable: Fertilizer
Dependent Variable: Plant Growth
Hypothesis: Giving plants fertilizer will help them grow faster than plants with no fertilizer.
Controls: Type of plant, watering routine, temperatures, amount of sunlight.
Explanation:
Independent variable always modifies the dependent variable.
Dependent variable always changes based off of the independent variable.
The hypothesis must be a statement that can be tested with an experiment.
Control variables should stay the same throughout the experiment in order for the experiment to be testable and accurate.

"Immediately prior to ventricular systole, pressure in the aorta is about" "The Frank-Starling law of the heart states that"
Answer:
80 mm Hg
Explanation:
Immediately prior to ventricular systole, pressure in the aorta is about 80 mm Hg. This can be explained by the Frank-Starling Law which states that the stroke volume of the left ventricle will increase as the left ventricular volume increases due to the myocyte stretch which tends to cause a more forceful systolic contraction. This applies in the case that all of the other factors remain the same during that time.
What section of a lab report should be phrased in an "If (cause), then (effect)" statement?
le
Answer:
The HYPOTHESIS
Explanation:
In an experiment, the formulation of the hypothesis is a critical part of the scientific method. The hypothesis is testable explanation given after making an observation in an experiment. In other words, an hypothesis is a predictive statement given that is subject to testing via experimentation.
The essence of formulating an hypothesis is to relate the effect of a possible solution on an observed problem. The "hypothesis" section of a laboratory report is usually identified by the use of an IF and THEN phrases in the statement. IF represents the cause, while THEN represents the effect. For example, a hypothesis can read; If plants are placed under white light (cause), then they will grow faster in height (effect).

Unicellular cells must carry out ___ of life.(1 point) A. all functions B. a few functions C. a single function D. specific functions
Answer:
all functions
Explanation:
To survive, unicellular cells must carry out all functions.
Hope this helps!
Unicellular cells must carry out all functions of life. Thus, the correct option is A.
What are Unicellular cells?Unicellular cells may be defined as those organisms that generally consist of only a single cell. This single cell carries all the essential functions of life which are required in order to survive in nature.
The complexity of the genome in a such single-celled organism is very simple. The mechanism of compartmentalization is not found inside the cell of such organisms. All the functions are carried out by the same cell.
Examples of unicellular organisms are Bacteria, amoeba, Paramecium, archaea, protozoa, unicellular algae, and unicellular fungi. They possess a cell wall made up of peptidoglycan, chitin, or other forms of polysaccharides. This protect the inner content of the cell.
Therefore, unicellular cells must carry out all functions of life. Thus, the correct option is A.
