Thymine is the nitrogenous base that is unique only to DNA.
NUCLEIC ACIDS:
Nucleic acid are biological molecules that store and transmit genetic information in living cells. The two nucleic acids are RNA and DNA. DNA and RNA are structurally made up of nucleotides that contain nitrogenous bases, phosphate groups and pentose sugar. The four nitrogenous bases are Adenine, Cytosine, Guanine and Thymine/Uracil. Thymine is only present in DNA while Uracil is only present in RNA. Other nitrogenous bases can be found in both nucleic acids. Therefore, Thymine is the nitrogenous base that is unique only to DNA.Learn more at: https://brainly.com/question/14090794?referrer=searchResults
Is it possible for energy to be transferred directly from the first trophic level to the third trophic level? Explain.
During energy transfer, 10% of the energy is transferred to the next trophic level and 90% is lost to the environment. Energy transfers from one trophic level to the next trophic level and not the third trophic level.
What is Energy transfer?Energy transfer is the amount of energy at each trophic level which is transferred to the next trophic level. Energy decreases as it moves through an ecosystem. As little as 10% of the energy at any trophic level is transferred to the next level and the rest is lost largely through metabolic processes as heat energy.
From each trophic level to the next trophic level, about 90% of the starting energy is unavailable to the next trophic level because the energy is used for different processes such as movement, growth, respiration, and reproduction and some energy is lost as heat.

CAN SOME ONE HELP ME WITH 8-12 PLZ!!!!!!!!!!!!
Answer:
8.Active Transport
9.phospholipid
10.facilitated diffusion
11.osmosis
12.ATP
Explanation:
Active transport is similar to osmosis but it happens with other substances
The phospholipid is shaped like a ball with two legs coming out and the legs connect on both sides of the cell to help protect the membrane and to help provide pathways.
Facilitated diffusion is just what is happening when the material or substance is going through the membrane which is either active or passive.
Osmosis is when the water passes through the membrane from a less concentrated place to a high concentrated place
ATP is energy used to help material or substance through the cell however only certain types of material need the energy to pass through some don't require energy at all
Explain why worms have outer skin as their respiratory surface rather then lungs. NO google answer. ASAP
The simple answer for that will be that they are not complex organisms. Earthworms are simple organism with the small body,
So as there body is not that big thus they don't need any specialized organ system for the process of respiration. Every organism has the complex systems according to fulfill their needs, and most certainly the skin is very convenient medium for the respiration by the diffusion process.
-------------------------------------------------------------------------------------------------------------
BLOOD CIRCULATORY SYSTEM:They have a specialized system where it was needed, THE BLOOD CIRCULATION SYSTEM, There body is small but long and need blood to transfer the oxygen to each part of the body. There blood have the haemoglobin(it carries the oxygen), thus it is red just like us.
--------------------------------------------------------------------------------------------------------------
SKIN:Skin as a respiratory medium, needs to be thin, wet and cover large surface area than volume. The Skin fulfills all these Prerequisites, thus it is a perfect organ for the respiration. Even our respiratory medium which is alveoli is wet, thin and cover REALLY large surface area more than our body. If the skin dries, there will be no diffusion and worm will die due to dessication.

does the rate of alcoholic fermentation differ when different types of sugar are used as a source of energy! i need a claim n evidence!!!
Answer:
Explanation:
This question is a practical question and would require some sort of experiment. However, let's define what rate of reaction means. The rate of a chemical reaction (in this case fermentation) can be described as the speed at which the reaction occurs; meaning the speed at which product is formed per unit time.
The "claim" in the attachment in the question can be referred to as hypothesis since this question is an experiment. The null hypothesis here will be "the rate of alcoholic fermentation is not affected by the type of sugar used as an energy source".
The "evidence" from the attachment will be result of the experiment conducted which cannot be provided here.
However, the conclusion of this experiment (which also answers the main question; does the rate of alcoholic fermentation differ when different types of sugar are used as a source of energy?) should show that the rate of alcoholic fermentation should differ based on the type of sugar used. This is because different enzymes are responsible for the conversion of this disaccharide to the glucose monosaccharide which is what finally undergoes alcoholic fermentation. For example sucrose is broken down into glucose and fructose by sucrase while lactose is broken down into glucose and galactose by the enzyme lactase.
Note that the reaction rate from glucose to produce CO₂ (a product of fermentation) will be the same (regardless of source) but the reaction time from the disaccharide to glucose will be different because of the difference in enzyme and can also be determined by comparing the time to produce the CO₂ by the sugars and the time to produce same amount of CO₂ when given water in the experiment .

xplain how organisms in lakes are related through the flow of energy. in environmental science
Answer:
Energy enters a community when plants and algae trap light energy during photosynthesis. They change the light energy into chemical energy in glucose, which then moves through the community as different organisms eat each other. Some energy is stored through fossilisation, while most of it is lost through heat dissipating into the environment.
Explanation:
Answer:Sample Response
The particles in a substance slow down when the average kinetic energy of the particles decreases. As the average kinetic energy decreases, the internal energy decreases, and so the thermal energy decreases. As the thermal energy of the substance decreases, the temperature decreases.

Predict whether each substance will dissolve in water. dissolves in water, does not dissolve in water
Answer: for HCO it dissolves in water
for CH2OH IT dissolves in water
Explanation:
i just took the test
It depends on the particular substance concerned that one can predict whether it will dissolve in water or not. Listed below are some general principles:
Things that usually dissolve in water include:
1. Ionic Compounds: Many salts, including sodium chloride (table salt), dissolve in water because of the attraction between positive and negative ions and polar water molecules.
2. Polar Compounds: Due to the similar polarity of water molecules, substances with polar molecules, such as sugar and ethanol, tend to dissolve in water.
3. Many gases Some gases, such as oxygen (O2) and carbon dioxide (CO2), can partially dissolve in water.
Things that usually don't dissolve in water include:
1. Oils, greases, and hydrocarbons are examples of non-polar substances that do not dissolve in water because water is a polar solvent and does not interact significantly with non-polar substances.
2. Insoluble salts: Some salts, such as lead(II) sulfide (PbS) and silver chloride (AgCl), have low solubility in water.

Answer: The cellular process that enables the cells to grow and develop into tissue is called MITOSIS.
Explanation:
The skin is the largest organ of the body that contains various cells which includes: the epidermal and dermal cells. With the various activities of man, the skin is susceptible to injury through burns.
The healing of the skin, especially injury sustained from burns involves the interaction between the different cell types. Recently, scientists can bioengineer skin in a laboratory to treat severe burns and other types of skin injuries which are grown from living cells.
MITOSIS is the cellular process that enables the cells to grow and develop into tissue. It is also defined as the process by which a cell duplicates into two genetically identical daughter cells.
The process of mitosis occurs in 4 stages; the prophase, metaphase, anaphase, and telophase. The various activities that occurs on these stages brings about the growth and the development of the cells into tissue.
The cellular process that enables cells to grow and develop into tissues is mitosis.
Mitosis allows a single cell to divide and form two morphologically and genetically identical cells. The two cells each also have the potential to divide if the conditions are right.
Thus, a single cell has the capacity to become tens, hundreds, or even thousands of cells as a result of mitotic division.
A tissue is formed from a group of cells that have differentiated to perform similar functions. In order words, without mitosis, there is absolutely no chance for tissues to be formed.

Oceans and seas can act as a heat reservoir to regulate climates. They can absorb great quantities of heat in the summer, with very little temperature change. In the winter, oceans and seas release the heat. This is the main reason why coastal climates are milder compared to inland climates. Which choice correctly explains this phenomenon? the high specific heat of water caused by hydrogen bonding the high specific heat of water caused by hydrogen bonding the high freezing point of water caused by the strength of its covalent bonds the high freezing point of water caused by the strength of its covalent bonds the high boiling point of water caused by hydrogen bonding the high boiling point of water caused by hydrogen bonding the high heat of vaporization of water caused by nonpolar bonds
Answer:
The high specific heat of water caused by hydrogen bonding
Explanation:
Specific heat capacity of a substance is the quantity of heat required to raise the temperature of a unit mass of that substance by one degree Celsius (1° C).
Due to the hydrogen bonding present in water, water has a high specific heat capacity of 4184 Joules per kilogram. This means that, water has to absorb 4,184 Joules of heat for the temperature of one kilogram of water to increase 1°C. When compared to other substances such as metals, this is very high. For example, the specific heat capacity of copper is 385 Joules per kilogram which means that it only takes 385 Joules of heat to raise 1 kilogram of copper 1°C.
Therefore water, can absorb a large quantity of heat with very little changes in its temperature. This property of water helps the oceans and seas to serve as heat reservoirs by absorbing a large quantity of heat in hotter seasons and releasing these heat in colder seasons.
