Matter and Chemical Formula
Let us learn about
Atoms and molecules
Element, compound and mixture
Chemical symbol and chemical formula
Atomicity and valency
Answer:
Atoms are the basic units comprising matter, and interact in a variety of ways.
Explanation
The most fundamental unit of matter that makes up elements is called atoms. Atoms comprise nucleus-orbiting electrons- while protons and nuetrons make up a stable nuclues. Here, the neutrons are uncharged, while the negatively charged electrons are attracted to the positively charged protons at the atom's center
The number of protons the atom determines its atomic number, and the sum of protons and neutrons determine the atomic mass.
Elements in the periodic table, are typically represented by chemical symbols- abbreviations of their atomic name. They are arranged in order of valency- atoms in the same group typically have the same number f electrons on their valence shells, and thus their physical properties behave similarly (conductivity, melting points, boiling points).
Valence electrons, on outer valence shells, also influence bonding. The atoms donate, accept or share valence electrons in order to achieve more stable atoms. Bonding between elements form molecules, that may interact with molecules to form compounds.
what is the role of a catalyst?
Answer:
Catalysts make such a breaking and rebuilding happen more efficiently. They do this by lowering the activation energy for the chemical reaction. Activation energy is the amount of energy needed to allow the chemical reaction to occur. The catalyst just changes the path to the new chemical partnership

if there's 23% cytosine how much adenine
I'm going to tell you how to find the answer yourself so you can figure out other problems like it.
First, DNA is made up of those four nucleic acids. Adenine always pairs with Thymine in DNA. Guanine always pairs with Cytocine.
Therefore, the amount of Adenine will always equal the amount of Thymine in DNA. The amount of Guanine will always equal the amount of Cytocine.
So, if Adenine equals 23% of your sample and Adenine equals Thymine, then Thymine equals 23%.
Add the amounts of Adenine and Thymine. 23% + 23% = 46%
100% - 46% =
That gives you the percentage of Cytocine and Guanine together. Since they are in equal amounts, divide by two and you have the percentage of each.

why are region called promoters essential to RNA transcription?
Answer:
A promoter is a region of DNA where transcription of a gene is initiated. Promoters are a vital component of expression vectors because they control the binding of RNA polymerase to DNA. RNA polymerase transcribes DNA to mRNA which is ultimately translated into a functional protein.

1. W pewnym małżeństwie zarówno mężczyzna, jak i kobieta mają grupę krwi AB. Podaj genotyp mężczyzny i kobiety, a następnie określ, jakie grupy krwi mogą mieć dzieci tej pary. W tym celu uzupełnij krzyżówkę genetyczną: Genotyp kobiety: Genotyp mężczyzny: Krzyżówka: K- kobieta - pionowo, M – mężczyzna- poziomo
Answer:
A, B and AB blood groups.
Explanation:
If both a man and a woman have the blood type AB, the couple's children have A, B and AB blood groups. the reason behind these types of blood groups are the similar blood group of both male and female. According to blood type chart, a male with AB blood group married with female with the same blood group AB, it will never produce O blood group only A, B and AB blood groups.

What should be my key concept for How much salt will it take to make an egg float.
The density of the average egg will be slightly greater than that of water, so it will sink. To make the egg float, we have to make the water more dense by adding salt. For 1 cup of water, adding 3 tbsp. of salt should be about enough to make the egg float.
In the rat, the allele for red eye colour is dominant over the alleles for brown colour. Consider a cross between a rat that is an Hozygote dominant for eye colour and a rat that is an Hozygote recessive for eye colour.
1. Show the parental genetic cross between the two rats.
2. Use a Punnett square to show the F1 (filial generation).
3. Indicate the genotype and phenotype of the F1 generation.
4. With the results of the F1 generation, construct a Punnett square showing the results of an F2 (generation).
5. Indicate the genotype and phenotype of the F2 generation
Answer:
1) RR x rr
2) Shown below
3) 100% Rr with red eyes
4) Punnett square shown (Rr x Rr)
5) 25% of the offspring are h0m0zygous dominant with red eyes (RR), 50% are heterozygous with red eyes (Rr), and 25% are h0m0zygous with brown eyes (rr)
Explanation:
Let's say the allele for red eyes is R and the allele for brown eyes is r.
1. A cross between a h0m0zygous dominant (two copies of the dominant allele, R) and h0m0zygous recessive (two copies of the recessive allele, r) is: RR x rr
2. R R
r Rr Rr
r Rr Rr
The F1 generation is shown in the Punnett square above.
3. The F1 generation are 100% Rr. They are heterozygous. Since red (R) is dominant, the rats all have red eyes
4. A cross between the F1 generation (Rr x Rr) gives the F2 generation
R r
R RR Rr
r Rr rr
5. 25% of the offspring are h0m0zygous dominant with red eyes (RR), 50% are heterozygous with red eyes (Rr), and 25% are h0m0zygous with brown eyes (rr)

Answer:
Consequences of the widespread use of plastic materials can be an increase in levels pollution and the overflowing of landfills because most plastics are non-biodegradable and can take a very long time to disappear unlike things like paper which are biodegradable.

Describe nondisjunction and the effect it can have on a human.
Answer: Nondisjunction is the failure of one or more pairs of homologous chromosomes or sister chromatids to separate normally during mitosis or meiosis. During mitosis, this can cause cancer. During meiosis, this can cause Down syndrome, Turner's syndrome, and Klinefelter's syndrome.
The San Marcos salamander, Eurycea nana, is a light reddish-brown
translucent salamander about 2-5 cm in length. E. nana is found only in
Spring Lake and a portion of the San Marcos River.
Which human activity would most likely decrease the ability of the
salamanders to survive?
The addition of a new food source into the river that limits competition for
resources
Tourism that helps fund the educational programs related to river ecosystem
conservation
Public transportation that reduces the number of automobiles that contribute to
pollution runoff into the river
Increasing water consumption that decreases the flow of clean water from the
springs that feed the river
Answer: Increasing water consumption that decreases the flow of clean water from the
springs that feed the river
Explanation: Because the salamanders have less clean water, pollution becomes more of a problem, also all of the other options would help the salamanders.
The human activity that would most likely decrease the ability of the salamanders to survive is increasing water consumption, which decreases the flow of clean water from the springs that feed the river, which is the last option.
What are the human activities that lead to habitat loss?The salamander is only found in a limited area of the San Marcos River, which relies on clean water from the springs, so decreasing the flow of clean water would negatively impact the salamander's survival, as it depends on specific water conditions for survival. As water is withdrawn from the springs to meet human needs, such as agriculture, industry, or household use, less water is available, which can have a detrimental effect on the habitat that the salamander requires because of human needs.
Hence, increasing water consumption decreases the flow of clean water from the springs that feed the river, so the last option is the correct option.

Name THREE ways Earth’s oceans affect your life.
The ocean is good for animals, animals need the water and animals help the water in some type of way. And half of the people including me loves sea animals, so without the ocean, there will be no sea animals.
And the ocean is good because it produces oxygen and carbon dioxide.
Three ways by which Earth's ocean affects your life are it supplies freshwater (most rain comes from the ocean) and nearly all of Earth's oxygen. The ocean moderates the Earth's climate influences our weather and impacts human health.
What are the oceans' effects?It offers food, medications, minerals, and sources of renewable energy. Fishing, seafood, pleasure, and science are all supported by it. Our ocean is the first "super-highway," connecting economies and moving people and things around the world.
Animals benefit from the ocean, as they both need and contribute to the water in some form. And since I am one of the people that like sea life, there wouldn't be any sea life without the ocean.
Therefore, additionally, the ocean is beneficial since it emits carbon dioxide and oxygen.
