Protect bacteria from unfavorable conditions

mrs_skeptik [129]

The likely answer here is spore coat.

Several types of bacteria will form a spore when they are presented with unfavorable conditions. When conditions improve, the spore germinates and the bacteria continues to replicate.

What is the term for the interior posterior surface of the eyeball that includes the retina, optic disc, macula and posterior po

Lina20 [59]

Answer:

Fundus.

Explanation:

The fundus or ophthalmoscopy consists of viewing the retina and the optic disc through the pupil and the transparent media of the eyeball (cornea, aqueous humor, crystalline humor, and vitreous humor) including the optic disc, retinal vessels, macular area and fundus as a whole. It is an important component of the clinical evaluation of many diseases and is the only location where the vascular bed can be observed in vivo in a bloodless manner. The direct ophthalmoscope is available to perform it in Primary Care (PC) consultations and in other specialties, this is an optical instrument that directs light directly onto the retina through a mirror that reflects a ray from the light source. This mirror has a central hole that allows the observer to view the illuminated retina. The major retinal vessels are examined and tracked distally as far as possible in each of the four quadrants (superior, inferior, temporal, and nasal). The color, tortuosity, and caliber of the vessels are examined. The posterior pole is between the temporal vascular arches, measures 5-6 mm, and is where most of the lesions in diabetic retinopathy are located, such as microaneurysms, hemorrhages or exudates.

You have been hired as a field assistant for a researcher interested in the evolution of flower characteristics in orchids. Comp

chubhunter [2.5K]

Answer:

$\text{Present a flower with one characteristic changed to the normal pollinator. }$ $\text{As a control, present a flower with no characteristics changed to the normal pollinator}$

$\text{Record any measure of pollination success}$

$\text{Repeeat for flowers with other characteristics changed}$

$\text{Analyze the data to determine which altered characteristics affect pollination }$ $\text{success the most. This characteristic will be the result of the experiment.}$

Explanation:

The missing information is attached below.

$\text{Present a flower with one characteristic changed to the normal pollinator. }$ $\text{As a control, present a flower with no characteristics changed to the normal pollinator}$

For the control, you'll need something you're already familiar with. In this scenario, a normal flower with no changes in characteristics is the best control. And if no data is accessible, you still have data on the success rate of a typical flower, which can be used as a guideline. And, for the initial configuration, you can only adjust one characteristic so it would be easier to maintain track of and analyze the data gathered.

$\text{Record any measure of pollination success}$

Since the aim of your experiment is to examine the influence of flower characteristics on pollination performance, you should keep track of the active pollination events. To have more accurate results, this would require listing the total number of plants that were to be pollinated.

$\text{Repeeat for flowers with other characteristics changed}$

Once you've completed the initial examination, you'll need to run tests on various characteristics to see whether they have some impact on pollination performance. To see the importance of different characters on pollination, change only one trait in flowers; if you'd like to research combined results, create pairs and change them together.

$\text{Analyze the data to determine which altered characteristics affect pollination }$ $\text{success the most. This characteristic will be the result of the experiment.}$

Your outcome is also the one that has gotten the most constructive or negative reviews. If some changed characteristic significantly affected the number of pollination efficiency, that is your outcome, because that is what you can mention as a good result and pollination enhancer.
