A nurse is planning to give a preschool child an immunization consisting of bacterial cells that have been modified. what is the substance called?

Answers

Answer 1

Vaccine.

A vaccine is a biological preparation that provides immunity to a specific disease. Vaccines are usually made from weakened or killed forms of a microorganism (e.g. bacteria and viruses), its toxins or its surface proteins. When administered, they stimulate and "train" the body's immune system to recognize, attack, and destroy these microorganisms when the body encounters them in the future.

flow of energy in an ecosystem

Answer:

Trophic levels and energy flow on food chains

Explanation:

The trophic level in a food chain (or web) corresponds to the position of each living being in relation to its energy and nutrient flow in relation to the others.

There are three types of basic trophic levels:

Producers - Plants and other photosynthetic and chemosynthetic organisms

Consumers (food chains usually have more than one) - Herbivores, Carnivores and Omnivores

Decomposers - Bacteria and Fungi

An example food chain according to trophic levels:

Phytoplankton(producer) → Krill (1st consumer) → Penguin (2nd consumer) → Seal (3rd consumer) → fungi and bacteria (decomposers)

Also, it is important to highlight that at each trophic level, less energy is absorbed when a living being consumes the previous one, so the more trophic levels a chain has, the lower the energy flow at the end.

Describe the stages of photosynthesis. use the terms thylakoid, light-dependent reactions, and light-independent reactions in your answer.

Answers

Final answer:

Photosynthesis has two stages, the light-dependent reactions that generate energy via sun absorption in the thylakoids, and the light-independent reactions (Calvin cycle) that use this energy to produce sugar in the stroma.

Explanation:

Photosynthesis occurs in two key stages: the light-dependent reactions and the light-independent reactions (also known as the Calvin cycle). The light-dependent reactions take place within the thylakoid membranes of the chloroplasts, and their role is to absorb energy from sunlight and convert it into stored chemical energy, resulting in the formation of adenosine triphosphate (ATP) and the reduction of NADP+ to NADPH. These are the energy carriers.

Subsequently, the energy stored in ATP and NADPH powers the Calvin cycle. This light-independent reaction takes place in the stroma of the chloroplasts and involves the fixation of atmospheric CO₂ into sugar molecules. The ATP and NADPH generated by the light-dependent reactions provide the energy for these reactions.

Do you think large cells and small cells carry out diffusion and osmosis at equal efficiency? why or why not?

Answers

The answer to this question would be: No, the bigger cell will have a higher rate of osmosis/diffusion.

Osmosis and diffusion will happen in all of the surfaces of the cell membrane. The Bigger cell will have bigger volume and wider membrane surface area. That means the cell can do diffusion and osmosis in the wider area, thus have more speed than smaller cells.

A. Click on the link here to learn more about the Great Salt Lake

B. Answer the following questions:

1. Describe 3 abiotic conditions (depth, salinity, temperature, etc.) of the Great Salt Lake.(3 points)

2. Explain how the 3 abiotic factors you listed in #1 change depending on the time of the year (winter vs. summer). (3 points)

3. Explain how the abiotic conditions affect the life cycle of the brine shrimp (i.e. hatching, reproducing, etc.) (2 points)

4. Limiting factors are resources or other factors in the environment that can lower the population growth rate. List at least two limiting factors in the Great Salt Lake and explain why each one can be limiting. (2 points)

Answers

1. Depth: The water level in the Great Salt Lake fluctuates from year to year. Water levels drop and salinity increases when less water flows into the lake than usual. Not only that, but the wetlands dry up and the shoreline recedes. The reason the shoreline shifts so dramatically is because it sits at the bottom of a broad and relatively flat basin. For a visual example, think of pouring water into a plate versus a bowl.
Salinity: This Great Salt Lake has a high mineral content, as most terminal lakes are, which means that it is quite salty. Even the fresh water flowing into the lake contains small amounts of dissolved minerals. As water evaporates from the lake, the minerals stay behind. As a result, these minerals have accumulated to very high levels because they have been left behind for thousands of years. The Great Salt Lake is between 3.5 and 8 times saltier than the ocean. However, the organisms that survive in such saline conditions have adapted to their surroundings through special features.
Temperature: The Great Salt Lake has a very shallow depth, with an average of 14 feet deep and a mere maximum of 33 feet. This means that a lot of the surface area is exposed to the air, and is at the mercy of its seasonal temperature fluctuations. In the summer, rise to more than 80 degrees Fahrenheit while falling to below freezing in the winter.
2. Depth: Salinity drops and lake levels rise during high precipitation years. Wetlands get covered by salt water, and the shoreline expands, sometimes destroying wildlife habitats and killing sensitive vegetation.
Salinity: Changes in lake elevation are accompanied by changes in salinity. The salinity in the lake decreases as incoming fresh water dilutes the salt water. This happens during the wet years. During dry years, however, salinity increases as continued evaporation removes fresh water.
Temperature: Because of the lake's salt high content, the water doesn't usually freeze. However, as the temperature drops during the winter, less saline zones freeze solid, and most of the lake turns into a vivid pea-soup green color. In mid-March, temperatures begin to rise again as brine shrimp begin hatching. By late April, juvenile, and adult brine shrimp fill the water, serving as food for migrating and breeding birds.
3. Brine shrimp are smaller in highly salty water and larger in less salty water. Also, salinity levels also affect the rate of sexual development. Higher salinities produce adults who reach maturity quicker but are shorter in length. As salinity increases, the abdomen becomes longer relative to body length. Low salinity may also cause cysts to crack prematurely, as well as allowing other competitors into the ecosystem. High salinity results in offspring that develop quickly but are smaller and have a relatively longer abdomen. In short, effects of abiotic conditions on brine shrimp are development rate, the rate of sexual maturity, the overall length of the abdomen, amount/type of food available, cyst density and location.
4. One limiting factor of brine shrimp are predators: corixids that consume brine shrimp, grebes that consume brine shrimp and their cysts, and humans that commercially harvest brine shrimp cysts. Another limiting factor for brine shrimp is cooler temperatures. They are much more productive in warmer water and consume more phytoplankton. However, when the lake water temperature is cold, the shrimp population tends to decline.

True or false? on average, 20% of the emergency room patients at greenwood general hospital lack health insurance. in a random sample of 4 patients, the probability that only one patient will be uninsured is 0.4096.

Answers

To solve this, we use the binomial probability equation.

P = [n! / (n – r)! r!] p^r * q^(n – r)

where n is the total number of sample patients = 4, r is the number of uninsured patients = 1, p is probability of being uninsured = 0.20, q is 1 – p = 0.80

Calculating for probability P:

P = [4! / (4 -1)! 1!] 0.20^1 * 0.80^(4 – 1)

P = 0.4096

Read the excerpt from "Mother Tongue." Those tests were constructed around items like fill-in-the-blank sentence completion, such as “Even though Tom was ______, Mary thought he was _____.” And the correct answer always seemed to be the most bland combinations of thoughts, for example, “Even though Tom was foolish, Mary thought he was ridiculous.” Well, according to my mother, there were very few limitations as to what Tom could have been and what Mary might have thought of him. So I never did well on tests like that. Which information from the excerpt best supports the inference that achievement tests ignore imagination as an element of language ability? Tan’s mother would not be able to answer a question like the one described in the excerpt. Tan’s mother could think of several ways to answer a question like the one described in the excerpt. Tan’s mother did not allow her to take tests with questions like the one described in the excerpt. Tan’s mother was disappointed that Tan did poorly on tests with questions like the one described in the excerpt.

Answers

The correct option is this: TAN'S MOTHER COULD THINK OF SEVERAL WAYS TO ANSWER A QUESTION LIKE THE ONE DESCRIBED IN THE EXCERPT.
From the passage, it can be seen that, Tan's mother believed that so many things would have fit exactly into those blanks that are present in the questions given to Tan. This shows that the mother's imagination is very active and that those that set those questions have ignored imagination ability of the students.

The best detail in this question that describes the inference that was made is that Tan’s mother could think of several ways to answer a question like the one described in the excerpt.

The summary of the excerpt

What this excerpt means is that if Tan's mother was asked to answer the blanks she would think of a lot of ways to do this.

From the excerpt, we can see that there are blank spaces in the test that was given. The author said that the answers usually provided in the blanks by students are unimaginative and bland.

The author is trying to tell the reader that these tests are not a true test of one's ability to speak the English language.

She refers to her mother as a very imaginative person that can answer the question creatively in different ways.

If some HCl drips down the outside of your graduated cylinder when you are filling the cylinder, use a neutralizer absorbent to clean up the spill. You can neutralize acid with soda ash or with sodium bicarbonate. Use pH paper to determine if the spill has been neutralized. The used absorbents should be placed in plastic bag and dispose appropriately.

Final answer:

When m HCl spills on a graduated cylinder, immediately rinse the cylinder with water and dry it, while wearing personal protective equipment for safety.

Explanation:

If some m HCl (hydrochloric acid) drips down the outside of your graduated cylinder while you are filling the cylinder, it is important to act promptly and safely to mitigate any potential hazards. First, immediately rinse the outside of the graduated cylinder with plenty of water to dilute and wash away the acid. This step ensures that the acid does not harm you, others, or the surface on which the cylinder is placed.

Secondly, after safely diluting the acid, dry the outside of the cylinder with a clean lab towel or paper to prevent any slipping or potential accidents. Always wear appropriate personal protective equipment, such as gloves and eye protection, when handling acids and other corrosive substances. Remember, safety in the laboratory is paramount, and knowing how to properly respond to spills and drips is an essential part of laboratory work.
