Answer:

vapourization

Explanation:

When the water is heated, it changes into water vapour which is called vapourization or sometimes we can also call it evaporation.

Answer:

In science, accepted theories do not represent absolute truths. A scientific theory is accepted when there is much evidence available that support its statements, but new lines of evidence can modify original presumptions  

Explanation:

A scientific theory is a plausible explanation of a particular phenomenon of the natural world, which has been many times tested and verified by using the scientific method. The accepted theories are progressively modified (or even overturned) as new lines of evidence emerge. In consequence, a scientific theory is composed of statements that we consider as truths regarding the available evidence, but we have no absolute certainty that such statements are true. The ability to self-correct is fundamental in science and it happens when we discover that the original statements of a scientific theory were wrong, thereby new lines of evidence allow us to correct the error and/or develop new scientific theories.

Answer:

The lower limit is 0.65°C

The upper limit is 1.05°C

the average is 0.85°C

The difference between the average and the lower limit is:

0.85°C - 0.65°C = 0.20°C

the difference between th average and the upper limit is:

0.85°C - 1.05°C = -0.20°C

Then we can write the change in temperature as:

T = 0.85°C ± 0.20°C

Now we want to find the error bar.

The error bar would be the total distance between the lowest value and the largest value.

Then the error bar is:

1.05°C - 0.65°C = 0.40°C

notice that the error bar is twice the error, which makes a lot of sense because the error (± 0.20°C) goes up and down.

Then the error bar in this measure has a magnitude of 0.40°C.

Answer:

1000 MM individuals; 2000 MN individuals; 1000 NN individuals

Explanation:

The Hardy-Weinberg principle states that, under certain conditions, the frequency of alleles and genotypes in a sexually reproducing population will remain constant over generations. The Hardy-Weinberg assumptions include random mating, sexual reproduction, and the absence of evolutionary forces such as mutation, natural selection, and genetic drift (as in the example above). Under these conditions, the frequency of alleles and genotypes in a population will not change and tend to the equilibrium. In this case, under Hardy-Weinberg equilibrium, the frequency of the M allele or 'p' must be equal to 0.5, and the frequency of the N allele or 'q' must be equal to 0.5 (i.e., the sum of all allele frequencies in the population must be equal to 1). Moreover, the frequencies of the genotypes will be p², 2pq, and q² >> p² (MM genotype) = (0.5)² = 0.25; q² (NN genotype) = (0.5)²  = 0.25; and 2 x p x q (MN genotype) = 2 x 0.5 x 0.5 = 0.50. In consequence, under Hardy-Weinberg equilibrium, in a population of 4000 diploid individuals (8000 alleles), we have

- 4000 M alleles (M = 0.5) and 4000 N alleles (N = 0.5);  

- 1000 MM individuals [p² >> (0.5)² = 0.25]; 2000 MN individuals (2pq >> 2 x 0.5 x 0.5 = 0.5) and 1000 NN individuals [q² >> (0.5)² = 0.25].

Answer:

Carbohydrate = 57.023g

Fats = 20.736g

Proteins = 25.919g

Explanation:

According to this question, Valerie is planning to eat at dinner meal that has a total of 800 Calories.

- 55% calories come from carbohydrate i.e. 55/100 × 800 = 440 calories

- 20% calories come from fat i.e. 20/100 × 800 = 160 calories

- 25% calories come from proteins i.e. 25/100 × 800 = 200 calories

Since 7.716 calories = 1g

1. Amount of carbohydrates in gram = 440/7.716 = 57.023g

2. Amount of fats in gram = 160/7.716 = 20.736g

3. Amount of proteins in gram = 200/7.716 = 25.919g

Answer:

1. Connects the larynx to the main bronchi k. trachea

2. Includes terminal and respiratory as subtypes b. bronchiole

3. Food passageway posterior to the trachea. e. esophagus

4. Covers the glottis during swallowing of food d. epiglottis

5. Contains the vocal cords g. larynx

6. Indentation on the lung where the lung root structures enter and exit f. hilum

7. Pleural layer lining the walls of the thorax j. parietal pleura

8. Site from which oxygen enters the pulmonary blood a. alveolus

9. Connects the middle ear to the nasopharynx. i. pharyngotympanic tube

10. Pleural layer in contact with the surface of the lung l. visceral pleura

11. Increases air turbulence in the nasal cavity c. conchae

12. Separates the oral cavity from the nasal cavity h. palate

Explanation:

1. The trachea is between the main bronchi and the larynx. It has semicircular rings of cartilage. The function of this organ is to conduct the air from the larynx to the primary/main bronchi.

2. After the primary (main), secondary, and tertiary bronchi, the terminal and the respiratory bronchioles come. They also conduct the air towards the alveoli so that the oxygen can enter the blood. The diameter of the bronchi terminal is smaller than the bronchi, and the diameter of the respiratory bronchi is smaller than the previous ones.

3 and 4. The esophagus is not part of the respiratory system. It is a tube that belongs to the digestive system since food has to pass through it to go to the stomach. The esophagus is posterior to the trachea, and the epiglottis closes the entrance to the larynx when we swallow to stop food from going to the lungs.

5. The vocal folds are in the larynx. This one is between the trachea and the pharynx. There are two types of vocal folds, the true and the false vocal folds. Both of them vibrate when air passes through them, allowing us to speak and make different tones.

6. The hilum is the lungs section where the bronchus, the pulmonary artery, and the pulmonary vein enter the lung. It is an indention that is in the middle part of the lungs.

7 and 10. The pleura has two sides, the parietal one and the visceral one. The first one is in contact with the lungs and the second one with the thorax's walls. Between them, there is a space called the pleural cavity. The cavity has fluid that allows the movement of the two pleurae. As a result, the lungs can move and fill with air.

8. After the respiratory bronchioles, we have the alveolar duct. The alveolar ducts lead to alveolar sacs. The alveolar sacs has the alveolus. They are thin walls that are in contact with capillaries. When the air is there, the oxygen passes through the thin walls. Then it goes through the capillaries' walls and into the blood.

9. The pharyngotympanic tube is also known as the Eustachian tube. It connects the middle ear to the nasopharynx. Its function is to regulate the pressure in the ear.

11. The conchae are in the nasal cavity. They are three projections in the nasal cavity, the inferior one, the middle one, and the superior. Their function is to increase the surface of the nasal cavity so that more air can enter with every inspiration. As they are projections, they modify the laminar airflow producing a turbulent flow.

12. The palate is between the nasal cavity and the oral cavity. It has two parts, the soft palate, and the hard palate. The palate helps in the production of certain sounds and divides the nasal cavity from the mouth.

Answer:

The majority of carbon on Earth is found in rocks and sediments, with the remainder found in the ocean, atmosphere, and living creatures. Carbon cycles pass through these reservoirs, or sinks.

Explanation:

For his school project, Noah wants to demonstrate the earth's natural primary carbon-producing source. His results suggest that sedimentary rocks are where the majority of the carbon on earth is preserved for future use.

The gradually building or deposition of mineral or organic particles at the Earth's surface, followed by cementation, is the process by which sedimentary rocks are formed. Sedimentation is the broad term employed to define the procedures which lead to the accumulation of these particles.

Sedimentary rocks are constructed from pre-existing rocks or remnants of extinct creatures. They emerge from deposits that amass on the Earth's surface. Apparent bedding or layering is particularly common in sedimentary rocks.

Thus, his results suggest that sedimentary rocks are where the majority of the carbon on earth is preserved for future use.

Explanation:

pH of coffee = 5

pH of solution = 10

Concentration of H+ ions between successive pH values are in multiples of 10

Hence, the pH difference :

pH of solution - pH of coffee

(10 - 5) = 5

Hence, difference in H+ ions will be :

10^5 = 10*10*10*10*10 = 100,000 times

Explanation:

Nitrogen is a fundamental component of both inorganic and organic compounds, where it is the main constituent of biomolecules such as nucleic acids (DNA, RNA) and proteins. The nitrogen cycle refers to the biogeochemical processes by which nitrogen circulates between the components of an ecosystem, i.e., between organisms (like plants and decomposers), and non-living things (i.e., soil, water, air). This cycle consists of several processes which include, among others, nitrogen fixation (i.e., the process by which nitrogen in the atmosphere is converted into ammonia), nitrification (i.e., the oxidation of ammonia is oxidized into nitrite and subsequent transformation of nitrites into nitrates), denitrification (where nitrate is reduced), anaerobic ammonia oxidation and putrefaction.

Positive feedback loop increases the response whereas a negative feedback loop decreases the response.

Positive feedback is the amplification of a body's response to a stimulus. For example, in childbirth, when the head of the fetus pushes up against the cervix (1) it stimulates a nerve impulse from the cervix to the brain (2).

A feedback mechanism resulting in the inhibition or the slowing down of a process.

Examples of processes that utilise negative feedback loops include homeostatic systems, such as thermoregulation (if body temperature changes, mechanisms are induced to restore normal levels), blood sugar regulation (insulin lowers blood glucose when levels are high ,glucagon raises blood glucose when levels are low).
