Answer:
The burning of the candle is an exothermic reaction. The candle is a paraffin wax which is made up of hydrocarbons. When the candle burns, it comes in the contact of oxygen, and there is a breaking of hydrocarbon bonds and hence the release of energy take placeWhy would dark moths have an advantage?
Answer:
They would have an advantage in places covered in items with their tone of "skin" Allowing them to camouflage and not be eaten
Explanation:
Couldn't find a better word for skin lol
How does the age of a tree relate to its size?
Answer:
Árbol de envejecimiento fórmula La fórmula de envejecimiento del árbol puede estimar la edad de un árbol multiplicando el diámetro del árbol por su factor de crecimiento. Es más exacto con bosque y árboles rurales en lugar de árboles urbanos, que a menudo se cultivan en condiciones menos ideales que pueden atrofiar su crecimient
Answer:
If you know when the tree was planted, you can easily and accurately determine its age. The second most accurate way to estimate tree age is to count the annual rings of wood growth. Annual rings can be counted using two different methods. You can extract an increment core from the tree using an increment borer.
Explanation:
The zinc chloride produced by the reaction is in what state
Answer: Solution in Water
Explanation:
I believe this refers to the reaction between Zinc and Hydrochloric acid.
When this happens, the solution will be Zinc Chloride but as it happened in a solution (the acid), the resulting Zinc Chloride salt would be in aqueous form which means that it would be a solution in water which is the other product of this reaction.
Had the zinc reacted with gaseous HCI, it would have resulted in a Zinc Chloride with no liquid in it.

What is natural selection?
Answer:
Basically in simple terms, a process in which capable animals can adapt and live longer to their environment than to others. Like a light colored mice on dark rock wouldn't survive unlike dark colored mice
Explanation:
In nature, living organisms have to navigate conditions (such as severe heat, extreme cold, drought, predation, food scarcity, etc) surrounding their existence in order to survive.
The theory of evolution states that as they conquer these conditions, their behavior and physical abilities, and traits evolve and become efficient at doing so.
These traits are then passed on to their offspring via the process of reproduction.
The process by which their physical qualities change to survive their environment is called adaptation.
Those who are unable to evolve are terminated by the harsh conditions of nature. Those who are unable to pass their abilities to survive to their offspring also get wiped off. Those who adapt and reproduce are deemed to be selected naturally to survive hence the term - Natural Selection.
Hence natural selection is a component of evolution.
Evolutionists have stated that the Giraffe is an example of an animal that evolved. It developed a long neck to enable it to reach for food far off the ground and on trees when there was a condition that wiped off shrubs available for them to graze on easily off the ground.
As giraffes with longer necks grazed and fed well, they passed on the gene to their offspring whilst those without adequately long necks got terminated by nature.
Another example is given in the attached picture. The animal in the picture is a desert dragon lizard adapting the color of its skin to blend to its environment in order to escape being spotted by desert hawks that prey on them.

An E. coli cell contains about 15,000 ribosomes, which carry out protein synthesis. Assuming ribosomes are spherical and have a diameter of 20.0 nm, calculate the fraction of the E. coli cell volume that is occupied by ribosomes.
Answer:
14.57%
Explanation:
From the previous lesson, we understood that the Volume of E.coli = 4.13 × 10⁻¹⁹ m³
The diameter of the ribosome = 20 nm
Radius will be D/2 = 20 nm/2 = 10 nm
The volume of the sphere since the shape of the ribosome is spherical = 4πr³
∴
The volume for each ribosome = 4πr³
For 15000 ribosome, we have:
[tex]= 15000 \times (\dfrac{4}{3}\pi) ((10^{-8})^3)[/tex]
[tex]= 15000 \times (\dfrac{4}{3}\pi) (10^{-24})[/tex]
= 6.283 × 10⁻²⁰
Thus, the fraction of E.coli volume occupied by the ribosome can be determined by using the formula:
[tex]= \dfrac{Vol. \ of \ ribosome}{Vol. \ of \ E.coli}\times 100[/tex]
[tex]= \dfrac{6.283 \times 10^{-20}}{4.31 \times 10^{-19}}\times 100[/tex]
= 14.57%

The five basic types of chemical reactions are combination, decomposition, single-replacement, double-replacement, and combustion. Analyzing the reactants and products of a given reaction will allow you to place it into one of these categories. Some reactions will fit into more than one category.
If one strand of DNA has the sequence 5'ATCG 3', what would be the sequence of the matching DNA strand
Answer:
Each strand is made up of a sequence of four nucleotides, A, C, G, and T. The order of the nucleotide sequence encodes genetic information. Since the nucleotides pair in a predictable way — A with T, and C with G — each strand of the DNA is always complementary to the other.

Question 2 please help choices are prokaryote or eukaryote
Answer:
1. Circular chromosome, no mitosis = PROKARYOTES
2. Sterols in membrane, performs exocytosis = EUKARYOTES
3. Cell wall and mitochondria present = EUKARYOTES
4. Spirillum shape present = PROKARYOTES
Explanation:
Prokaryotes are organisms that notably lack a membrane bound nucleus while eukaryotes possess a membrane bound nucleus. Although, there exists other characteristics and features that distinguishes these two domains of organisms.
- Circular chromosome is a feature possessed by prokaryotic organisms e.g. bacteria. Also they do not undergo mitosis, instead they perform binary fission.
- Sterols are a class of lipids present in the membranes of all eukaryotes. Prokaryotes lack this feature. Also, eukaryotes perform the process of exocytosis, which is how eukaryotic cells release waste particles outside the cell.
- Mitochondria is a structure present only in eukaryotic organisms. Hence, an organism that possesses both cell wall and mitochondria is an EUKARYOTE.
- Spirillum is a characteristics of spiral shaped bacteria called spirochetes. Since bacteria are prokaryotic, hence, the spirillum shape is a prokaryote.
