Which quantity is the rate at which velocity changes? acceleration motion speed direction

Answers

Answer 1

Answer: Acceleration

Explanation :

Motion is the change in position of an object with time.Speed is the change in distance with time.Direction is the position towards which something moves.The rate of change with velocity is termed as acceleration.The formula for acceleration is

Acceleration = velocity / time

From this formula it is clearly seen that the change of velocity with time is acceleration.


Answer 2
Final answer:

Acceleration represents the rate at which velocity changes.

Explanation:

The quantity that represents the rate at which velocity changes is acceleration. Acceleration is the change in velocity over time, and it can be positive or negative depending on whether the object is speeding up or slowing down. For example, if a car is initially at rest and then starts accelerating, its velocity will increase over time.

Acceleration has numerous practical applications. In transportation, it determines the rate of change in velocity for vehicles, influencing speed, braking, and maneuvering. In engineering, understanding acceleration is crucial for designing machinery and structures that can withstand dynamic forces.  Overall, acceleration plays a pivotal role in various aspects of physics, engineering, technology, and daily life.

If placed in tap water, an animal cell will undergo lysis, whereas a plant cell will not. what accounts for this difference? if placed in tap water, an animal cell will undergo lysis, whereas a plant cell will not. what accounts for this difference? the relative impermeability of the plant cell wall to water expulsion of water by the plant cell's central vacuole the relative impermeability of the plant cell membrane to water the relative inelasticity and strength of the plant cell wall

Answers

IIRUWEUIUUUUUUUUUUUUUUUUUUUUUUUUUUUUUU
Final answer:

Animal cells lack a rigid outer structure and burst in hypotonic solutions like tap water, while plant cells have a strong cell wall that prevents lysis and uses a central vacuole to manage water intake, maintaining structural integrity and turgidity.

Explanation:

When an animal cell is placed in tap water, which is a hypotonic solution, it will swell and eventually undergo lysis (bursting) because it lacks a rigid outer structure to prevent over-expansion. In contrast, a plant cell has a rigid cell wall surrounding the plasma membrane, which provides structural support and prevents lysis in hypotonic situations. This cell wall can withstand the increase in water volume up to a certain point, creating turgor pressure within the cell that is beneficial for maintaining the plant's structure. Additionally, plant cells manage excess water using a large central vacuole, which stores water and supports the cell's turgidity.

The main reason a plant cell does not undergo lysis in tap water is due to the relative inelasticity and strength of the plant cell wall, which provides a protective barrier. Moreover, when a plant cell is exposed to a hypertonic environment, it undergoes plasmolysis where the plasma membrane detaches from the cell wall, but unlike an animal cell, the cell wall maintains the plant cell’s structural integrity.

Identify the correct flow of urine out of the body

Answers

You did not indicate any choices but urine goes out of the body through one track only so I will just talk about its pathway and the organs involved in the correct order. 

Urine is produced by the kidneys, bean-shaped organs that filter waste out of the blood that goes through them. Now the urine goes from the kidneys to two thin tubes called ureters. The ureters then empty urine into the urinary bladder. When the bladder fills up, it empties the stored urine into the urethra which opens to the outside of the body. 

So in summary urine pathway is:
Kidneys-ureters- urinary bladder-urethra-outside the body. 

Platelets are a type of blood cell also known as A. eosinophil. B. lymphocyte. C. monocytes. D. thrombocytes

Answers

They are also called thrombocytes.
Final answer:

Platelets, also known as thrombocytes, are cell fragments derived from megakaryocytes. They are involved in blood clotting and are released into the bloodstream. Thrombopoietin stimulates the production of megakaryoblasts, which mature into megakaryocytes and release platelets.

Explanation:

Platelets are more commonly known as thrombocytes, which are cell fragments rather than complete cells. They are derived from megakaryocytes, which are large cells found in the bone marrow. Thrombopoietin, a glycoprotein, stimulates the production of megakaryoblasts, which then mature into megakaryocytes and release platelets into the bloodstream. Each megakaryocyte can release thousands of platelets during its lifespan.

Which is not a major salivary gland? lingual glands parotid glands submandibular glands sublingual glands all of these choices are major salivary glands?

Answers

Yes all of these are

Final answer:

Lingual glands are not considered major salivary glands; the three major salivary glands are the parotid, submandibular, and sublingual glands, which secrete the bulk of saliva into the mouth.

Explanation:

Among the choices listed, lingual glands are not considered major salivary glands; rather, they are part of the numerous minor salivary glands present within the oral mucosa and tongue. The three pairs of major salivary glands that secrete the majority of saliva into the mouth are the parotid glands, the submandibular glands, and the sublingual glands. Of these, the parotid glands are located near the ears and secrete saliva into the mouth through the parotid duct. The submandibular glands are found in the floor of the mouth and release saliva through the submandibular ducts. Lastly, the sublingual glands lie below the tongue and utilize lesser sublingual ducts to secrete saliva into the oral cavity.

If a bottle of beer has 15 grams of carbohydrate, 0 grams of fat, 1 gram of protein and 15 grams of alcohol, approximately how many calories does it contain?

Answers

Final answer:

A bottle of beer with 15 grams of carbohydrate, 0 grams of fat, 1 gram of protein, and 15 grams of alcohol contains approximately 170.6 calories.

Explanation:

The number of calories in a bottle of beer can be calculated by multiplying the grams of each macronutrient by their respective calorie values and then summing them up. In this case, there are 15 grams of carbohydrate and 1 gram of protein, which contribute 4.1 calories per gram. There are also 15 grams of alcohol, which contributes 7 calories per gram. Since the bottle has 0 grams of fat, we don't need to consider its contribution. Therefore, the total calorie content of the beer is:

(15 grams of carbohydrate × 4.1 calories/gram) + (1 gram of protein × 4.1 calories/gram) + (15 grams of alcohol × 7 calories/gram) = 61.5 + 4.1 + 105 = 170.6 calories.

The bottle of beer contains approximately 169  calories.

1. Carbohydrates provide 4 calories per gram, so 15 grams of carbohydrate contribute 15× 4 = 60 calories.

2. Protein also provides 4 calories per gram, so 1 gram of protein contributes 1 × 4 = 4 calories.

3. Alcohol provides 7 calories per gram, so 15 grams of alcohol contribute 15× 7 = 105 calories.

4. Add the calories from carbohydrate, protein, and alcohol together: 60 (carbohydrates) + 4 (protein) + 105 (alcohol) = 169 calories.

5. Since fat content is 0 grams, there are no calories from fat.

6. Therefore, the total calories in the bottle of beer are approximately 169 calories.

What is the major cause of the greenhouse effect? view available hint(s) what is the major cause of the greenhouse effect? excessive carbon dioxide gas in the atmosphere disruption of nutrient cycles increases in the nitrogen cycle increased primary producer activity acid deposition due to nitric and sulfuric acid in the atmosphere?

Answers

The major causes of the greenhouse effect is excessive carbon dioxide gas in the atmosphere. The greenhouse effect is a process that warms the Earth's surface. When the Sun's energy reaches the Earth's atmosphere, some of it is reflected back to space and the rest is absorbed and re-radiated by green house gases, such as carbon dioxide, water vapor, metahne, nitrous oxide, and ozone. The absorbed energy warms the atmosphere and the surface of the Earth.
