Explain why a spark from a firework will not hurt you as much as a cup of hot tea?

Answers

Answer 1

Answer:

It will not unless it contains as much energy as the cup of tea. So a tiny spark may be at 1,000 Celsius  but a whole cup of tea at 90 Celsius  will deliver far more heat (energy) to the skin as the spark.

Why is the metric system more scientific than the English system?


A. The English system is older than the metric system, and so it is less relevant.


B. The English system is only used in English-speaking countries.

C. The English system was based on human traits, while the metric system was founded on physical constants.


D. The English system must be converted to the metric system using conversion factors.

Answers

Answer:

Unlike the British Imperial System, the metric system, or SI (from the French Système International), is based on a natural constant.

Explanation:

The metric system is more scientific than the English system because the English system was based on human traits, while the metric system was founded on physical constants.

What do you mean by the Metric system?

The metric system may be defined as the scientific way of measuring weights, and distance in kilograms and meters respectively with the help of a decimal system.

The metric system may also be known as the SI system. SI system is not based on the human traits rather then it depends on the natural constant. It is more precise, standard, and easy to understand.

Therefore, the correct option for this question is C.

Answer:

In the alveoli, where there is high pO2, low pCO2, lesser H+ concentration and lower temperature, the factors are all favourable for the formation of oxyhaemoglobin, whereas in the tissues, where low pO2, high pCO2, high H+ concentration and higher temperature exist, the conditions are favourable for dissociation of oxygen from the oxyhaemoglobin. This clearly indicates that oxygen gets bound to haemoglobin in the lung surface and gets dissociated at the tissues

Draw the structure of ATP molecule and explain how it is formed​

Answers

ATP is formed from the breakdown of glucose molecule in mitochondria of the cell.

ATP molecule is formed in the process of respiration i.e. aerobic and anaerobic. During aerobic cellular respiration, glucose reacts with oxygen in the mitochondria of the cell, forming ATP that can be used by the cell in different cellular activities. When glucose reacts with oxygen, three molecules are formed i.e. ATP, Carbon dioxide and water. ATP is used by the cell whereas the Water and carbon dioxide molecules are waste materials which are removed from the cell so we can say ATP is formed from the breakdown of glucose molecule in mitochondria of the cell.

Answers

Carbon is transfered by plants and animals.

Carbon flows between plants and animals, environmental storage centers that absorb and store carbon for long periods of time. Thus, the correct option is A.

What is Carbon cycle?

Carbon cycle is one of the main biogeochemical cycles which has four main steps. In this first, carbon enters into the atmosphere as CO₂. CO₂ is absorbed by the autotrophs such as green plants for photosynthesis. Then, the animals consume plants as food, thereby, incorporating the carbon into their system. Afterwards, animals and plants die, their bodies decompose and the carbon is reabsorbed back into the atmosphere.

In this, plants use carbon dioxide for photosynthesis. Through this, they remove the inorganic carbon from the atmosphere and incorporate it into the plant's tissues in the form of sugars such as glucose, sucrose and starch. Animals get carbon by eating the plants or by hunting other animals.

Therefore, the correct option is A.

Answers

Answer:

Fourth option

Explanation:

ATP - Adenosine Triphosphate (3Ps), ADP - Adenosine Diphosphate (2Ps). ATP breaks down into ADP because it loses a Phosphate Anion in whatever process that the ATP is becoming ADP.

In the image provided, fourth image shows how ATP breaks down into ADP. Option D is the correct answer.

ATP (adenosine triphosphate) is a molecule that stores and provides energy for cellular processes. When ATP is used, it undergoes a process called hydrolysis, where a water molecule is used to break a high-energy phosphate bond in ATP. Option D is the correct answer.

During this hydrolysis process, one of the phosphate groups in ATP is cleaved off, resulting in the formation of ADP (adenosine diphosphate) and an inorganic phosphate (Pi). The energy stored in the phosphate bond is released, making it available for cellular functions. The breakdown of ATP into ADP allows the released energy to be utilized by cells for various activities, such as muscle contraction, active transport, and synthesis of molecules.
