Which of the following is not a type of biological contamination?
A)bacteria
B)protozoa
C)viruses
D)herbicides

Answers

Herbicides are not a type of biological contamination since they are toxic substances that are not living things.

Biological contamination is the contamination by living microorganisms that are toxic. Herbicides are not the type of biological contamination. Thus, option D is correct.

What are biological contaminations?

The contamination of the food, water, air, or soil due to harmful living organisms is called biological contamination. These microbes cause diseases and illnesses in the other species.

Viruses, bacteria, and protozoans are the biological contaminants that result in diseases and pollution. On the other hand, herbicides are chemical substances that are used to kill the pests infesting the crops.

Therefore, herbicides are not biological contaminants.

20. A research company wants to design a new type of artificial heart valve that will be less likely to be rejected by a person's immune system. Which step in the design process should the company perform before building a prototype of the heart valve?
A. Find test subjects for the new heart valve.
B. Conduct research on existing artificial heart valves.
C. Determine how to manufacture the new heart valve.
D. Evaluate the performance of the artificial heart valve.​

Answers

Answer:

C. Determine how to manufacture the new heart valve.

I think it seems a little obvious (I'm probably wrong)because obviously before doing something important your going to think about how to do it first.

The step in the design process that should the company perform before building a prototype of the heart valve is to determine how to manufacture the new heart valve. Thus, the correct option for this question is C.

What is meant by a Prototype?

A prototype may be defined as a sample, model, or liberation of a product that is significantly built in order to test a concept or process. This term is used in a variety of contexts, including semantics, design, electronics, and software programming.

A prototype is typically utilized in order to determine a new design to increase precision by system analysts and users. If an organization or individual wants to design any type of structural and functional unit, they must require to know its actual mechanism of it.

Then they are allowed to manufacture the concept with regard to their discovery. So, a research company requires to demonstrate how to manufacture the new heart valve with the help of a prototype.

Therefore, the correct option for this question is C.

what was the problem with reusing contaminated water from other parts of the mill to extinguish the coke fires? From the book ‘When smoke ran like water’

Answers

Answer:

1. The problem with that was that the already poisonous water was made worse after using it to quench the flames from coke production.

2. It contaminated the soil, making it difficult for plants to grow.

Explanation:

As the author described the last stages of coke production, she explained that water was needed to quench the very hot flames from coke production. A 'bright fellow' suggested using dirty water from other parts of the mill to quench the flames from the coke production. The problems with this were;

1. The already contaminated water was made worse after it was used to quench the flames from coke.

2. Mrs. LaMendola noted that she was unable to grow her tomatoes in the path where the plumes from the oven ran. So the contaminated water negatively affected the soil.

The problem that should be already poisonous water is also made worse when it quenches the flames at the time when the production of the coke should be done.

Also, it contaminated the soil also it is difficult for growing the plants.

The problem of reusing contaminated water:

Since the author explained the last coke production stage so here the water required to quench that it should be very hot flames arise from the coke production. Also, the contaminated water should be worse whenever it is used for quenching the flames. Also, the contaminated water does not positively impact the soil.

In certain rats, black fur is dominant over white fur, If two rats that are both heterozygous for fur colored are mated, what would their offspring be expected to have?

Answers

Answer:

Three different genotypes and two different  colors

Explanation:

Because both rats have heterozygous genes, meaning they have 2 different alleles, ex: "Yy") The offspring can have different genotypes and colors because the parents have heterozygous genes.

hope this helps!

The offsprings of the cross between two heterozygous rats will have the following genotypes: BB (black), Bb (black) and bb (white).

According to this question, a gene coding for fur color in rats is involved. The allele coding for black fur (B) is dominant over the allele for white fur (b).

If two rats that are both heterozygous for fur are crossed i.e. Bb × Bb, gametes B and b will be produced by both rats. Using this gamete in a punnet square (see image), the following offsprings will be produced: BB, Bb and bb.

BB - black offspringBb - black offspringbb - white offspring

Therefore, the offsprings of the cross between two heterozygous rats will have the following genotypes: BB (black), Bb (black) and bb (white).

Answers

Answer:

1. Pollen tube

2. Style

3. Ovary

Explanation:

This process is describing the process of POLLINATION, which is the transfer of pollen grains from the anther of a male flower (androecium) to the stigma of the female flower (gymnoecium). After pollination i.e. the pollen has landed on the sticky stigma, the pollen grows out a tube called POLLEN TUBE.

The pollen tube extends through the STYLE of the female flower called PISTIL to the OVARY. The ovary is the reproductive part of the female flower that produces the ovules, which the sperm in the pollen is about to fertilize.

This eruption led to the death of 57 people, in addition to permanently changing the surrounding landscape. It is still one of the most disastrous volcanic eruptions in recent history.(2) Mount St. Helens is located in the Cascade Mountain Range in Washington, United States. It is part of the Ring of Fire, an important geological area. This area is home to over 160 active volcanos. Volcanos are active if they have erupted at least once in the last 10,000 years. Mount St. Helens is a stratovolcano. This means it is a steep, evenly shaped cone made of many layers of volcanic rock and ash. These volcanos often have explosive eruptions.(3) Before the eruption of Mount St. Helens, a bulge of rock formed on the northern side of the mountain. Then, early on May 18th, an earthquake occurred that was caused by increasing pressure inside the mountain. This led to a landslide. The force of the landslide collapsed the entire northern side of the mountain, which led to a lateral blast. Lateral blasts occur when volcanos erupt sideways, rather than at the peak. This lateral blast sent rocks flying for miles at high speeds. These blasts destroy forests, buildings, and other structures in a short amount of time. The lateral blast at Mount St. Helens destroyed an area of about 150 square miles. It destroyed forests and left debris in three-inch layers, making the situation even more disastrous.(4) When Mount St. Helens erupted, clouds of deadly ash, volcanic rock, and pyroclastic flows flew outward from the volcano. Pyroclastic flows are more dangerous than lava flows. They are made of gas and volcanic matter. The temperature inside one can reach 1832 F. They move at a speed of more than 50 miles per hour. It is impossible for humans and animals to outrun them. These flows make the eruption of stratovolcanos deadly. As a result, the forests covering the mountain were ruined. Fortunately, there weren't any towns near enough to be destroyed.(5) By the time Mount St. Helens finished erupting, a crater had formed at its top. Forests had been destroyed for miles and rivers had been blocked by debris. Clouds had even blocked out the sun in the entire state. It took years for the environment to recover.How does the fifth paragraph support the main idea of the article that the eruption at Mount St. Helens was dangerous and had lasting effects?
