You have been hired as a field assistant for a researcher interested in the evolution of flower characteristics in orchids. Complete an experiment that determines whether color, size, shape, scent, or amount of nectar is the most important factor in attracting pollinators to a particular species. Assume that you can change any flower's color with a dye and that you can remove petals or nectar stores, add particular scents, add nectar by injection, or switch parts among species by cutting and gluing. Match the terms in the left column to the appropriate blanks in the sentences on the right. Not all terms will be used.
a. one characteristic.
b. pollination success.
c. aiters others characteristics.
d. affects pollination success the most.
e. has no effect on pollination.
f. other characteristics.
g. no characteristics.
h. all characteristics.
1. Present a flower with____changed to the normal pollinator. As a control, presenta flower with____changed to the normal pollinator has no effect on pollination
2. Record any measure of____.
3. Repeat for flowers with changed all characteristics other characteristics no characteristics alters other characteristics This characteristic will be____.
4. Analyze the data to determine which altered characteristic____.This characteristic will be the result of the experiment.

Answers

Answer:

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

[tex]\text{Record any measure of pollination success}[/tex]

[tex]\text{Repeeat for flowers with other characteristics changed}[/tex]

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

Explanation:

The missing information is attached below.

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

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.

[tex]\text{Record any measure of pollination success}[/tex]

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.

[tex]\text{Repeeat for flowers with other characteristics changed}[/tex]

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.

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

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.

What are the similarities between the coastal oceans and coral reefs

Answers

Answer:A coral reef is an underwater ecosystem characterized by reef-building corals. Reefs are formed of colonies of coral polyps held together by calcium carbonate. ... Unlike sea anemones, corals secrete hard carbonate exoskeletons that support and protect the coral.

Coastal oceans are commonly defined as the areas from the shoreline to the outer edge of the continental margin. They connect the continents to the open ocean and serve as a link for transporting organic and inorganic, natural and anthropogenic material from land to sea.

Coastal oceans in tropical areas have similar characteristics to their temperate counterparts. ... Coral reefs are biologically diverse and rich habitats that occur in relatively nutrient-poor environments along coastlines. Areas that have too many nutrients often harbor too much algal growth to sustain coral growth.,

Which of the following is the best example of an economic approach to reduce overfishing for a fish species with a declining population?
A The federal government sets a catch limit (per person or per boat) for the species and imposes a tax on any extra fish that are caught
B) A conservation agency creates marine parks where the area is a no-catch zone for the species so that the species can recover and population size can increase.
The state government introduces a subsidy for large fishing companies to help them afford to hire more crew members.
D) An educational group produces signs and video clips to encourage individuals to buy locally caught seafood and to avoid eating big fish like tuna and shark

Answers

Answer:

A

Explanation:

The fishing industry is a rapidly growing and expanding industry, which is concerned with the processing, preserving, selling, or culturing of fish products.

The correct answer is:

Option A. the federal government sets a catch limit (per person or boat) for the species and imposes a tax on any extra fish that are caught.

The Fishing industries in the United States are controlled by the:

Federal Government Fish and Game Commission Legislature

The catch limit for the species is set by the federal government. The federal government supports the fisheries by improving coastal employment, food production, fisher's welfare, and sustainability of the fishing sector.

Thus, option A is correct.

A 1.0-kb DNA fragment from the 5' end of the mouse gene is examined by DNA footprint protection analysis. Two samples are end-labeled with 32P, and one of the two is mixed with TFIIB, TFIID, and RNA polymerase II. Both samples are exposed to DNase I. The results are displayed below. The DNA exposed to proteins is run in the right-hand lane of the gel. Control DNA is in the left-hand lane.

Required:
What length of DNA is bound by the transcriptional proteins?

Answers

Answer:

Explanation:

Proteins, such as RNA (ribonucleic acid) polymerase, were loaded into lane 2. TFIIB and TFIID are two forms of TFII. These proteins attach to the fragment of DNA. Furthermore, these proteins shield DNA from the DNase enzyme, which may trigger DNA to split. As a result of the above findings, we may conclude that the inserting proteins(RNA polymerase, TFIID and TR 8 proteins) cover the area between 500 and 800 bp (base pair) in the DNase I footprinting experiment.

As a consequence, the length duration is 300bp since the promoter area is about 500-800bp and is not digested by DNase after incubation of inserting proteins.

Explanation:

What is the functions of the digestive, excretory, respiratory, circulatory, and lymphatic systems, and how do they interact to maintain the body's homeostasis?

Answers

Explanation:

Food and liquids are processed by the digestive system. After nutrients are absorbed during digestion, the excretory system removes solid waste products, or feces, through the rectum. The excretory system also works with the respiratory and circulatory systems and removes carbon dioxide (CO2) from the body.

Homeostasis, which refers to the body's capacity to maintain a steady internal environment despite changes in the external environment, is a state that is maintained by the respiratory, circulatory, lymphatic, excretory, and digestive systems working in concert. Although each of these systems has a unique job to do, they are all interrelated and dependent on one another to keep the body running smoothly.

What is a digestive system charge of ?

The digestive system is in charge of converting food into nutrients that the body can absorb. It consists of the liver, pancreas, small and large intestines, stomach, mouth, oesophagus, and stomach. After then, the circulatory system delivers nutrients to the body's cells.

The kidneys, ureters, bladder, and urethra are part of it. The circulatory system and the excretory system collaborate closely to move waste materials to the kidneys for filtering and expulsion from the body.

The respiratory system is in charge of supplying the body with oxygen and expelling carbon dioxide. It consists of the lungs, trachea, bronchi, nose, and mouth. The respiratory system collaborates with the circulatory system to eliminate carbon dioxide and provide oxygen to the body's cells.

Nutrients, oxygen, and waste products are moved throughout the body through the circulatory system. It consists of the blood, blood vessels, and the heart. To provide nutrition and oxygen to the cells and eliminate waste, the circulatory system collaborates closely with the respiratory and digestive systems.

It is the job of the lymphatic system to remove extra fluid from bodily tissues and transport it back to the circulatory system. It consists of lymphatic organs like the spleen and thymus, lymph nodes, and lymphatic arteries. The lymphatic system contributes to immunological function and aids in the body's defence against illnesses and infections.

Overall, through controlling the body's internal environment, these systems cooperate to preserve homeostasis. For instance, the excretory system eliminates waste while the digestive system supplies nutrients for the body. These nutrients and waste materials are delivered to and removed from the body's cells via the circulatory system. The lymphatic system helps the body fight infections while the respiratory system supplies oxygen for cellular respiration.
