Most articles pass right through the atom, this means that most of the atom is an empty space.
What is an atom?An atom is described as a particle that consists of a nucleus of protons and neutrons surrounded by a cloud of electrons.
Protons and neutrons make up the core nucleus of an atom, which is encircled by an electron cloud. In relation to the size of the atom as a whole, the nucleus is exceedingly small.
As a result, the electrons surrounding the nucleus are the primary target of interactions when particles or even light pass through an atom. The majority of the atom's remaining space, which includes the nucleus, is vacant.

The human body produces 60 billion (60,000,000,000) new cells per day. How many cells does it produce in one hour?
Answer:
E.g. E. coli—20 min, so in an hour 1 cell would turn into 8.
Given that 60 billion cells are produced in a day in the human body, the number of cells that will be produced in an hour can be calculated by dividing the number of cells by the number of hours in a day. There would be approximately 2.5 billion cells produced in one hour.
How frequently are the cells in our body renewed?The human body regularly replaces its own cells. Every day, roughly 330 billion cells, or 1% of all our cells are replaced. The equivalent of a new you will have been replenished in 80 to 100 days with 30 trillion.

Article name: New Research Shows Plants Are Photosynthesizing More in Response to More CO2 in the Atmosphere
BY LAWRENCE BERKELEY NATIONAL LABORATORY DECEMBER 17, 2021
Article states that "plants take up carbon dioxide from atmosphere and convert it into food."
Explain how article supports the law of the conservation of matter?1.This supports the law of conservation of matter, which states that matter cannot be created or destroyed, and can only be transformed from one form to another. In this case, carbon dioxide in atmosphere is transformed into organic matter in form of plant tissue.
2. According to the article, new research shows that plants are photosynthesizing 5% more in response to increased levels of CO2 in atmosphere.
3.The article states that 5% increase in photosynthetic rate translates to additional 5 billion tons of carbon being removed from atmosphere each year.
4.Article suggests that increase in photosynthetic efficiency may be a result of plants having more CO2 available to them, which stimulates photosynthesis.
5.Laboratory procedure used to quantify photosynthetic efficiency involves measuring amount of chlorophyll fluorescence emitted by plant. This fluorescence provides a measure of amount of light energy absorbed by plant during photosynthesis.
6. Field procedure used to quantify photosynthetic efficiency involves measuring amount of carbon dioxide taken up by plant during photosynthesis. This is done by placing plant in sealed chamber and measuring change in carbon dioxide concentration over time.
7.The article suggests that potential "saturation" of carbon dioxide in the atmosphere could lead to a leveling off of increased photosynthetic rates observed in plants.
9.The potential "saturation" of carbon dioxide in atmosphere refers to point at which plants would no longer be able to increase photosynthetic rates in response to higher levels of atmospheric CO2. If ecological photosynthetic rates were to reach saturation, it would mean that plants would no longer be able to remove more carbon dioxide from atmosphere through photosynthesis.

3. Fossil fuels, such as coal, are used as energy resources. Answer the following questions
about the consumption rate of coal.
PLEASE HELP
Fossil fuels, like coal, are natural resources that are used for energy production. The burning of coal is a primary source of electricity production worldwide. However, this method of energy production comes at a cost to the environment and the world’s economy. The following are the questions about the consumption rate of coal.
What is the consumption rate of coal-The consumption rate of coal depends on several factors such as population growth, the price of coal, energy demand, technological advancements, economic policies, environmental regulations, and the availability of alternative energy sources. According to the International Energy Agency (IEA), global coal consumption was approximately 7,726 million tonnes of coal equivalent (Mtce) in 2019. China, India, and the United States are the largest coal consumers in the world. Coal consumption in China alone accounted for more than 50% of the world's total coal consumption. How much coal does the world consume per day-According to IEA, the world consumes about 21.2 million tonnes of coal per day, which is equivalent to 7.7 billion tonnes of coal per year.
This consumption rate is expected to decline in the future as more countries shift towards renewable energy sources.Is the consumption of coal sustainable-No, the consumption of coal is not sustainable. Coal is a non-renewable resource, which means that it is limited in supply and will eventually run out. Additionally, the burning of coal releases harmful greenhouse gases into the atmosphere, contributing to global warming and climate change. The mining of coal also has a negative impact on the environment, including deforestation, water pollution, and soil degradation. The consumption of coal is also not economically sustainable in the long run as it is becoming increasingly expensive to extract and process coal. In conclusion, while coal consumption has played a significant role in the global energy mix, it is not a sustainable energy source, and the world should focus on transitioning to cleaner and more renewable energy sources.

A scientist injected some cells with a drug that blocked glycolysis after NADH was formed, but before ATP and pyruvate were formed. All the other enzymes used in cellular metabolism were unaffected. How would the production of ATP in the cell be affected?
Answer:
The cell could not make ATP.
Explanation:
Glycolysis may be defined as the process in which a glucose molecule is broken down into the two molecules of the pyruvate. Pyruvate is used to produce energy through various pathways that depends upon the availability of the oxygen. However when the glycolysis in blocked and the pyruvate is not formed, then the cells would not be able to use either the fermentation or aerobic respiration or the perform citric acid cycle. So the cell does not make any ATP.
which measurement is likely the least accurate? Explain.
What observations and/or patterns do you see in the data?
Based on the information, we can infer that the measurement that could be the least probable is caudal peduncie depth strandard error. Also, the trend is for lake values to be higher than river values.
What difference do we see in the values in the table?To identify the values we must analyze the table and identify they are not the trends. In this case we can infer that the tendency is for the values of the lake to be higher than the values of the river because all the values of the lake are higher than those of the river.
On the other hand, we can infer that the value that could be the least successful is the peduncie depth strandard error because it shows equal values. However, if we take into account the previous values, it should not be the same in both cases.

5.) Morgan buys a male python from a snake dealer who tells him that the snake carries the albino allele. Morgan mates the snake with an albino female, and ten normally pigmented offspring are produced with zero albino offspring. Morgan rushes back to the snake dealer and demands his money back stating that the male he bought is not heterozygous for the albino allele because all of its offspring had normal pigmentation. Is Morgan’s position supported by genetic theory? Why?
From the illustration, Morgan's claim could be valid and his position is supported by genetic theory.
Dominant/recessive allelesIt can be inferred from the claim of the snake dealer that albinism in male python is a recessive trait. If this claim is true, let us assume that the albino allele is represented by b and the alternate form is B.
The genotype of the snake Morgan bought will be Bb as claimed by the dealer.
Morgan mated Bb snake with an albino snake which would be bb.

On The Origin of Species was published by Darwin in 1859. This book established the concept of "natural selection," the process whereby the organisms adapt throughout time as the features that are most appropriate for their environment survive and pass on to the next generation.
Explain about the book of "The Origin of Species"?After a five-year journey to South America and several Pacific Island locations to study plants, fauna, and fossils, English scientist Charles Darwin created the theory of natural selection.
With the publication of his best-selling book Just on Origin of Species in 1859, he popularized the concept of natural selection.The process by which communities of living things adapt and change is known as natural selection. A population's members are naturally varied, which means that they are all all distinctive in some ways. This variety indicates that some people have characteristics that are more environment-appropriate than others. Those that possess advantageous qualities, or adapted traits, are now more likely to live and procreate. The adaptable qualities are subsequently passed on to the next generation by these people.Thus, On The Origin of Species was published by Darwin in 1859. This book established the concept of "natural selection."
