13. which of the following traits of land plants protects the leaves and stems from drying out

Answer:

The extinction you are referring to is unclear, as there have been several mass extinctions throughout Earth's history. However, it is generally accepted that climate has played a significant role in many of these events. Prior to some of the mass extinctions, such as the Permian-Triassic extinction and the Cretaceous-Paleogene extinction, the climate was warm and tropical with high levels of carbon dioxide in the atmosphere. This warm climate was likely a contributing factor to the extinction, as it may have led to changes in sea level, ocean circulation, and weather patterns that disrupted ecosystems and caused widespread extinction of species. However, it is important to note that climate is just one of many factors that can contribute to mass extinction events, and there are often multiple causes involved.

The ratio between 92 mL and 3.0 fl oz is 46 : 44, or it can be further simplified to 23 : 22.

To find the ratio between 92 mL and 3.0 fl oz, we need to convert the units to a common measurement. Let's convert 3.0 fl oz to milliliters (mL).

1 fluid ounce (fl oz) is equal to approximately 29.5735 milliliters (mL).

Therefore, 3.0 fl oz is equal to 3.0 * 29.5735 = 88.72 mL (rounded to two decimal places).

Now we can express the ratio between 92 mL and 88.72 mL:

92 mL : 88.72 mL

Simplifying the ratio by dividing both sides by the greatest common divisor, we get:

46 : 44

So, the ratio between 92 mL and 3.0 fl oz is 46 : 44, or it can be further simplified to 23 : 22.

The diameter of the field of view for the high power objective lens (50X) can be calculated using the following formula:

Field of view (mm) = Ruler size (mm) / Magnification

Plugging in the values given in the question, we get:

Field of view (mm) = 1.5 mm / 50X

This simplifies to:

Field of view (mm) = 0.03 mm

So the diameter of the field of view for the high power objective lens (50X) is 0.03 mm.

Based on the symptoms, physical examination, and recent history of antibiotics, Liz may be suffering from Clostridium difficile (C. diff) infection. Antibiotics may eliminate healthy gut bacteria, allowing C. diff to proliferate. The symptoms include watery diarrhea, abdominal pain with cramping, and a fever.

A physical examination of the patient reveals a protuberant abdomen and low blood pressure. Additionally, routine blood draw workup shows an elevation in her white blood cell count. A Clostridium difficile stool test may also be conducted for accurate diagnosis. The best treatment option for C. diff infection is discontinuing the antibiotics and beginning a new antibiotic that specifically targets C. diff.

Some of the antibiotics commonly used are metronidazole, vancomycin, and fidaxomicin. The choice of antibiotic will depend on the severity of the infection, recurrence history, and the patient’s health status. Additionally, adequate fluid intake is crucial to prevent dehydration caused by diarrhea. Probiotics are also effective for preventing or minimizing the severity of diarrhea.

In severe cases, hospitalization may be required to manage dehydration, electrolyte imbalance, and other complications. If C. diff recurs frequently, fecal microbiota transplantation (FMT) may be necessary to restore gut bacteria and eliminate C. diff.

According to the reading, Pseudomonas tend to grow in slimmy, irregular colonies. Which usually have fluorescent colors. So, Pseudomonas could be the best prediction possible with that information.

The dependent variable in the experiment conducted by Sara and Juan to test which soil is best for growing plants is likely the plant growth or the plant's response to the different types of soil.

This variable is dependent on the independent variable, which is the type of soil (sand, silt, clay, or the mixture) used in each pot. By observing and measuring the plant growth, they can determine which type of soil yields the best results in terms of seed germination and overall plant growth.

It's important to note that the dependent variable can vary depending on the specific focus of the experiment. In this case, since the aim is to determine the best soil for growing plants, the growth and development of the plants would be a relevant measure.

Other possible dependent variables could include factors like plant height, leaf size, number of leaves, or even the number of flowers or fruits produced. The specific measure chosen as the dependent variable would depend on the objectives and hypothesis of the experiment.

After tissue repair is completed, factor xii catalyzes the formation of a plasma enzyme called kallikrein, that, in turn, converts an inactive plasminogen into plasma , a fibrin-dissolving enzyme that breaks up the clot is true.

Plasma kallikrein was  set up to be a good activator ofpro-urokinase, the inactive zymogen form of urokinase. The complete activation ofpro-urokinase by tube kallikrein was  attained in 2 h with an enzyme/ substrate weight  rate of1/30. The rate of activation ofpro-urokinase by tube kallikrein was  similar to that catalyzed by plasmin and trypsin. The rate of activation ofpro-urokinase by factor XIIa was  roughly one- seventh of that by tube kallikrein. The activation of the zymogen was due to the  fractionalization of a single internal peptide bond, performing in the conversion of a single chainpro-urokinase( Mr = ,000) into two- chain urokinase( Mr = ,000 and,000), and these two chains were linked by a disulfide bond( s). These results indicate an important  part of tube kallikrein for the activation ofpro-urokinase in the factor XII-dependent  natural pathway of fibrinolysis.

Answer:The answer is "gene flow at work."

Explanation:

Answer: d.

Explanation:

The events described involve both mechanical and chemical weathering processes, highlighting the complex nature of how weathering affects geological structures.

The events can be identified as the result of mechanical weathering or chemical weathering as follows:

The minerals in a marble statue react with water to form acids and pores in the structure - This is an example of chemical weathering. The water reacts chemically with the minerals in the marble, causing them to dissolve and form acids. These acids further react with the marble, leading to the formation of pores and overall degradation of the statue's structure.

A piece of rock crumbles after being constantly thrashed by strong waves - This is an example of mechanical weathering. The constant thrashing of strong waves exerts physical force on the rock, causing it to break apart or crumble. This type of weathering occurs due to mechanical forces like abrasion, pressure, or impact that physically break down the rock into smaller pieces.

Industrial runoff forms cracks in a rocky structure in its path - This is a combination of chemical and mechanical weathering. The industrial runoff may contain acidic or corrosive substances that chemically react with the minerals in the rock, leading to their dissolution or weakening. The cracks in the rocky structure may also be a result of the mechanical force exerted by the flowing runoff, causing physical fractures in the rock.

The rocks in a region are streaked orange after being exposed to repeated rains - This is an example of chemical weathering. The repeated rains introduce water into the rocks, which may contain dissolved iron compounds. Over time, these iron compounds oxidize in the presence of water and oxygen, leading to the formation of orange-colored iron oxide minerals, such as rust. The streaking of rocks with orange indicates the chemical transformation of the minerals due to the weathering process.

In summary, the events described involve both mechanical and chemical weathering processes, highlighting the complex nature of how weathering affects geological structures. Mechanical weathering involves physical forces breaking down rocks, while chemical weathering involves chemical reactions leading to the alteration or dissolution of minerals.

The statement "The body stores excess fat in nephrocytes." is false because excess fat is stored in the adipose tissue.

Fat is a waxy substance that is made up of esters of fatty acids. It is necessary for body structural growth, but excess fat causes weight gain and many diseases.

Adipose tissues are found under the skin cell and under the cell of internal organs. They develop due to the accumulation of fats, they are also called fat cells. It is also called energy reservoirs.

Nephrocytes are present in the kidney, and they function as storage of excretory material. They do not store excess fats. Excess fat is stored by the adipose tissue in the form of triglycerides. The fat produces energy at the time of need.
