According to the data in the table, what percent of the elodea cells is water? Explain how you arrived at this conclusion.

Answers

Answer:

99%

Explanation:

at a salt solution concentration of 2%, plasmolysis first started to occur.  So the other 98% in the "solution" would have just been water. Since  water inside cells needs to be greater than the amount of water outside the cells, we can say that the amount of water inside the elodea cells was 99% so that it can allow hypertonic plasmolysis to occur.

Which is held constant when a gas obeys Boyle's law?

A. motion
B. pressure
C. temperature
D. volume

Answers

Answer:

B

Explanation:

ganyan rin sagot ko sa module ko

When a gas obeys Boyle's law, the temperature is held constant. The correct option is C.

What is Boyle's law?

Boyle's law is given by Charles Boyle. It is a gas law that states the pressure decrease with the increase in the volume and the temperature remain constant. In other words, the pressure exerted on gas is inversely proportional to the volume of the gas.

The law shows the relationship between pressure and volume, with the temperature remaining constant. There are three gas laws which are given by different scientists. These laws show the relationship between two variables and the third remains constant. These variables are temperature, volume, and pressure.

Thus, the correct option is C. temperature regarding the gas obeys Boyle's law, and it remains constant.

which cells divide more often than other cells?

Help

Answers

That means we lose around 50 million cells every day. This is a lot of skin cells to replace, making cell division in skin cells is so important. Other cells, like nerve and brain cells, divide much less often.

Skin cells need to divide as you grow. Hair follicle cells divide to produce more hair. Your lining cells (ex: stomach) and intestinal wall cells need to divide to provide new surfaces. Some cells like blood cells, nerve cells, and muscle cells do not divide after some time.

Identify the natural processes that occur on the earth's surface to make and destroy rocks.

Answers

The physical processes on Earth create constant change. These processes—including movement in the tectonic plates in the crust, wind and water erosion, and deposition—shape features on Earth's surface.

Answer:

You learned about the three rock types: igneous, sedimentary, and metamorphic. You also learned that all of these rocks can change. In fact, any rock can change to become any other type of rock. These changes usually happen very slowly. Some changes happen below Earth’s surface. Some changes happen above ground. These changes are all part of the rock cycle. The rock cycle describes each of the main types of rocks, how they form, and how they change.

The figure below shows how the three main rock types are related to each other (Figure below). The arrows within the circle show how one type of rock may change to rock of another type. These are the processes that change one rock type to another rock type.

Why are some pathogenic bacteria able to make toxins?

Answers

A pathogen is a microorganism that is able to cause disease in a plant, animal or insect. Pathogenicity is the ability to produce disease in a host organism. Microbes express their pathogenicity by means of their virulence, a term which refers to the degree of pathogenicity of the microbe. Hence, the determinants of virulence of a pathogen are any of its genetic or biochemical or structural features that enable it to produce disease in a host.

The relationship between a host and a pathogen is dynamic, since each modifies the activities and functions of the other. The outcome of such a relationship depends on the virulence of the pathogen and the relative degree of resistance or susceptibility of the host, due mainly to the effectiveness of the host defense mechanisms. Staphylococcus aureus, arguably the most prevalent pathogen of humans, may cause up to one third of all bacterial diseases ranging from boils and pimples to food poisoning, to septicemia and toxic shock. Electron micrograph from Visuals Unlimited, with permission.

The Underlying Mechanisms of Bacterial Pathogenicity

Two broad qualities of pathogenic bacteria underlie the means by which they cause disease:
1. Invasiveness is the ability to invade tissues. It encompasses mechanisms for colonization (adherence and initial multiplication), production of extracellular substances which facilitate invasion (invasins) and ability to bypass or overcome host defense mechanisms.

2. Toxigenesis is the ability to produce toxins. Bacteria may produce two types of toxins called exotoxins and endotoxins. Exotoxins are released from bacterial cells and may act at tissue sites removed from the site of bacterial growth. Endotoxins are cell-associated substance. (In a classic sense, the term endotoxin refers to the lipopolysaccharide component of the outer membrane of Gram-negative bacteria). However, endotoxins may be released from growing bacterial cells and cells that are lysed as a result of effective host defense (e.g. lysozyme) or the activities of certain antibiotics (e.g. penicillins and cephalosporins). Hence, bacterial toxins, both soluble and cell-associated, may be transported by blood and lymph and cause cytotoxic effects at tissue sites remote from the original point of invasion or growth. Some bacterial toxins may also act at the site of colonization and play a role in invasion. Acid-fast stain of Mycobacterium tuberculosis, the agent of tuberculosis (TB). The bacteria are the small pink-staining rods. More than one-third of the world population is infected. The organism has caused more human deaths than any other bacterium in the history of mankind. Although its ability to produce disease is multifactorial, it is not completely understood. American Society of Microbiology, with permission.
