Answers

Answer 1
Answer: Structures in the mouth region of the Annelids vary in a wider range. There are some annelids evolve jaws , which can be used in seizing their victims and preys, biting pieces of vegetation, or grasping decomposing matter. Even though some have evolved their jaws, majority of them are filter feeders. What lacks them that most advanced animals have? they dont have teeth.

How does putting salt on frozen roads make the roads less icy?

Answers

Hi, Sulikjon!
The main purpose it to lower the freezing point of water, and we use salt for this. 
I hope this helps;)
Icy sidewalks and roadways can lead to disasters. Wintertime slick surfaces can cause a variety of problems, from a simple slip to a major car accident. To prevent property damage, injury or death, it's important for surfaces to be de-iced. This is usually done by distributing sand, chemical de-icers or salt over the ice. Of these three, salt is the most common.

In the context of the difference threshold, _____ is the principle that two stimuli must differ by a constant proportion to be perceived as different.

Answers

Answer:

The answer is Weber's law

Explanation:

In the context of the difference threshold, Weber's law is the principle that two stimuli must differ by a constant proportion to be perceived as different.

- Weber's Law states that "for the difference to be perceptible, two stimuli must differ by a constant proportion, not a constant amount".

Which of the following statements best describes the structure and function of a carbohydrate?A. Carbohydrates are made up of starchy monomers and are used for structure, protection, and reproduction.
B. Carbohydrates are made up of sucrose molecules that are important for transportation and protein synthesis.
C. carbohydrates are large molecules made up of monosaccharides and are used by organisms for energy storage.
D. Carbohydrates are long, winding molecules made up of amino acids and are important in the synthesis of fats and hormones.

Answers

Answer: The correct answer is C. Carbohydrates are large molecules made up of monosaccharides and are used by organisms for energy storage.

Carbohydrates are the large group of organic compounds, which are comprised of Carbon, hydrogen, and Oxygen. They mainly include simple sugar (like glucose, fructose) and starch ( present in food like potato, grains).

They are the most essential and readily available source of energy for all life forms.

Complex carbohydrates ( polysaccharides) like starch are made up of simple sugar called monosaccharide ( like glucose).

Thus, option C) is the right answer.


Final answer:

Carbohydrates are large molecules made up of monosaccharides and are used by organisms primarily for energy storage.

Explanation:

The statement that most accurately describes the structure and function of a carbohydrate is 'Carbohydrates are large molecules made up of monosaccharides and are used by organisms for energy storage.' Carbohydrates are indeed large, complex molecules that are composed of smaller subunits known as monosaccharides.

They serve several essential functions in organisms, one of the most critical one being the storage and provision of energy. When organisms ingest carbohydrates, these molecules are broken down and converted into glucose, which is then used to fuel various cellular activities.

Can a catalyst be used over and over again?

Answers

Yes they can because the catalyst does not take part in the chemical reaction and remains unchanged after the reaction has ended.  Biological catalysts are known to be recycled by the bodies in which they work.

Jomari is diagnosed with hyperosmolar hyperglycemic nonketotic syndrome (HHNS) is stabilized and prepared for discharge. When preparing the client for discharge and home management, which of the following statements indicates that the client understands her condition and how to control it? A. "I can avoid getting sick by not becoming dehydrated and by paying attention to my need to urinate, drink, or eat more than usual."
B. "If I experience trembling, weakness, and headache, I should drink a glass of soda that contains sugar."
C. "I will have to monitor my blood glucose level closely and notify the physician if it s constantly elevated."
D. "If I begin to feel especially hungry and thirsty, I ll eat a snack high in carbohydrates."

Answers

Answer:

A. "I can avoid getting sick by not becoming dehydrated and by paying attention to my need to urinate, drink, or eat more than usual

Explanation:

HHNS is a clinical complication of diabetes usually type ii. where the blood sugar levels is exceedingly  high. This  condition is not mark with high concentration of ketone bodies  of the blood.

Due to rapid rise in blood glucose in HHNS mostly in type 2 diabetes, Excess glucose is excreted in the urine, and water follows by osmosis, leading to excess urine production (polyuria). With  loss of body fluids(dehydration set in) and need to take more fluid(polydipsia follows) . Because the body cells lack glucose, due to  the failure of insulin receptors which enable insulin to  facilitate glucose   entry  into cells, hunger sets  in and  excessive urge to eat (polyphagia) occurs.

Therefore, Jomari  need to be conscious of dehydration.By taking enough fluid to stabilize the body fluid balance, and  avoid  intake of too much sugar which will cause polyuria, polydipsia and polypahgia.

Jomari also need to be on the watch if the rate of micturition(urine passage)  is higher than normal or if thirst and hunger rates are excessively high so that  needed medical intervention could be provided.

Identify the benefits to native species of joining similar habitats with corridors.

Answers

Answer;

More species and more resources

Explanation;

The benefits to native species of joining similar habitats with corridors is more species and more resources.

Biodiversity corridors are areas of vegetation that allow animals to travel from one patch of native forest to another.

A corridor provides shelter, food and protection from predators by imitating the structure and diversity of native vegetation. Thus the benefits to a native species is more resources and also more species.

The benefit is that it permits migration between larger blocks of land The most likely is that they can exist but then they wouldn't be there fro so long because they'll be competing for the same resources
