Answer:
20% adenine, 20% thymine, 30% guanine, 30% cytosine
Explanation:
Edwin Chargaff stated in his rule that, in a DNA molecule, the amount of purine bases (Adenine and Guanine) should equate the amount of pyrimidine bases (Cytosine and Thymine). Mathematically, this means that;
A + G + C + T = 100%
Where;
% Adenine base = % Thymine base
% Guanine base = % Cytosine base
Hence, according to this question, the DNA molecule described will contain
20% adenine = 20% thymine,
30% guanine = 30% cytosine
20% A + 20% T + 30% G + 30% C = 100%

Answer:
The homogeneous mixture is only in the one phase of matter, whereas heterogeneous mixture is always in two or more than two different phases of matter. Solutions are termed as the homogeneous mixtures, on the other hand, suspensions or colloids are termed as the heterogeneous mixtures.
Examples:
Homogeneous:
Bronze: this alloy is an example of homogeneous substances since it is composed of tin and copper.
Milk : this mixture that we see in a uniform way is composed of substances such as water and fats.
Heterogeneous:
Mixtures in two or more phases are heterogeneous mixtures. Examples include ice cubes in a drink, sand and water, and salt and oil. The liquid that is immiscible form heterogeneous mixtures. A good example is a mixture of oil and water.

Essay on atoms 70 words
Answer:
The atom, the basic building block of matter, consists of a core nucleus surrounded by negatively charged electrons. Inside the atom nucleus contains a mixture of positively charged protons, and electrically neutral neutrons. All atomic electrons bind to the nucleus through electromagnetic force. A ground of electrons bound together will form individual molecules. An atom with an equal number of protons and electrons will hold neutral. An ion has positive or negative charge, either through a lack of electrons or an electron excess. The number of protons determines the formation of chemical elements, while as the number of neutrons determines the element's isotope. Most of the atom's mass has a concentration compacted within its nucleus; however, protons and neutrons hold about the same mass. Electrons bound to atoms hold a percentage of stable energy levels, otherwise known as orbitals, which undergo transitory processes through absorbing or omitting photons with equal energy levels. Electrons determine an element's chemical properties, thus influencing an atom's magnetic properties.

The carrying capacity of an ecosystem will most likely become unbalanced when?
Answer:
In a population at its carrying capacity, there are as many organisms of that species as the habitat can support. ... If resources are being used faster than they are being replenished, then the species has exceeded its carrying capacity. If this occurs, the population will then decrease in size.
Explanation:
When resources are depleted faster than they are replenished, the species has reached its carrying capacity. If this happens, the population will shrink in size.
What is carrying capacity?Carrying capacity is defined as the average population size of a species in a given habitat.
Environmental factors such as adequate food, shelter, water, and mates limit the species population size. If these requirements are not met, the population will decline until the resources recover.
Carrying capacity, or the maximum number of people that an environment can support over time without destroying or degrading it, is determined by three key factors: food availability, water availability, and space.
Carrying capacity is the maximum number, density, or biomass of people that a given area can sustainably support.
This is likely to change over time and is influenced by environmental factors, resources, and the presence of predators, disease agents, and competitors.
Thus, any disturbance in these factors can lead to an unbalanced carrying capacity.

D. 24 ATPs.
Cellular respiration uses one glucose molecule to produce a total of 38 ATPs (option B).
What is cellular respiration?Cellular respiration is the process by which cells obtain chemical energy by the consumption of oxygen and the release of carbon dioxide.
Cellular respiration occurs in three processes namely;
Glycolysis; this is the cellular degradation of the simple sugar glucose to yield pyruvic acid, and ATP as an energy source. Krebs cycle; this is a series of enzymatic reactions that occurs in all aerobic organisms; it involves the oxidative metabolism of acetyl units, and serves as the main source of cellular energy.Electron transport chain; this is a series of electron transfer that results in the synthesis of large amount of energy.In total, the overall process of cellular respiration results in the formation of 38ATPs.

an increase in the concentration of protons in the cytosol will most likely have which of the following effects on glycolysis
Answer:
Reaction rate will increase as a result of the increased H+ concentrate
Explanation:
Because the more ions the faster the reaction rate
The increase in the concentration of protons ; increases the Reaction rate
An increase in the number the positive ions ( H⁺ ) in a reaction will lead to an increase the reaction rate and a decrease in the activation energy.
Therefore as the number of protons ( H⁺ ) in the cytosol increases, the ripple effect it will have on glycolysis will be an increase in the rate of reaction ( i.e. Reaction rate ) and a decrease in activation energy.
Hence we can conclude that an increase in the concentration of protons in cytosol will increase the Reaction rate of glycolysis.

what makes angiosperm more advance than gymnosperm
Answer& Explanation:
Angiosperm is more advanced due to the mechanism of protection it has since developed as opposed to its predecessor, gymnosperm. Angiosperms could be deemed the inventors of animal-mediated pollination or dispersal, whereas gymnosperms mostly depend on wind-mediated pollination (which is far more of a gamble than animal mediated).
1) Angiosperms seeds are enclosed in fruits, which increases the chances of dispersal by either wind, water, or animals. Animals can eat the fruit and disperse the seeds via feces or by brushing the fruit off of their fur coats new areas of the terrain.
2)The development of flowers. Flowers are especially important because depending on the flower it can attract a set species of animals in order for pollination to occur. That species of animal could only focus on those few flowers and would allow the female part of the flower to receive pollen (produced by the male part of the flower) from all over the place. This theory is also applicable to animal mediated fruit dispersal.

What is the initial source of the energy in all food webs and food chains? Explain please
Answer:
The sun
Explanation:
The sun provides the light energy that plants need in order to produce glucose the animals gain after eating the plants or the animals that ate the plants.
The initial and ultimate source of the energy in all types of food webs and food chains is the Sun.
What is the primary source of energy?The Sun is the major source of energy for living organisms and the ecosystems of which they are a part on the Earth. Producers are the organisms of the food chain which produce energy such as plants, algae, and cyanobacteria. These organisms use the energy from sunlight to make organic matter from that of carbon dioxide and water molecules. This establishes the beginning of energy flow through almost all the food webs.
The light which is coming from the sun allows the green plants that is the producers to manufacture chemical energy which fuels all the cellular functions. In turn once the plants are eaten, this chemical energy and nutrients are transferred to the consumers and to other higher organisms.

Matthias Schleiden used a microscope to observe that the
parts of plants consist of cells. Theodor Schwann used a
microscope to observe that the parts of animals consist of
cells.
Which two statements did the work of Schleiden and Schwann add to the cell
theory?
A. All living things are made of one or more cells.
B. All cells come from other living cells.
C. Cells contain genetic material that consists of DNA.
D. The cell is the basic structural and functional unit of life.
Answer:
The work of Schleiden and Schwann provided to the Cell Theory the conclusions relating to that all living things are made of one or more cells and the cell is the basic structural and functional unit of life.
Explanation:
Matthias Schleiden was a German botanist who in 1937, while studying plant tissue under the microscope, observed that all plants are made up of cells.
In 1938, physiologist Theodor Schwann performed an experiment similar to Schleiden's, but using animal tissue, concluding that animals are made up of cells.
By bringing together the findings of both scientists, two important conclusions for Cell Theory were reached:
The cell is the structural and functional unit of all living beings. All living organisms are made up of one or more cells.Both conclusions are part of the cellular theory, as it is known today.
Regarding other options:
B. All cells come from other living cells was a conclusion provided by Rudolf Virchow.
C. Cells contain genetic material that consists of DNA is an argument that is not part of the cellular theory. In fact, the DNA would not be discovered until 1953.

Compared to the use of many gasoline vehicles with only one person per vehicle, this method of transportation conserves more fossil fuels.
Explanation:
A form of transportation —such as the subway or streetcar— has capacity for many passengers and uses electricity as an energy source. This means fewer people using gasoline-vehicles, which leads to savings in fossil fuels, such as gasoline or diesel.
The decrease in the use of fossil fuels in vehicles has been proposed as an alternative to reduce environmental pollution and its consequences. One alternative is to consider mass transport vehicles that use alternative energy, a sustainable form of transport.
None of the other options are correct, as they involve more or the same use of fossil fuels per person.

Mechanical waves include the movement of water, from ripples in a puddle to giant rolling waves on the surface of the open ocean. For example, water waves (mechanical waves) can transfer energy across an entire ocean basin, even though individual water molecules do not travel great distances.
Electromagnetic propagation through water is very different from propagation through the air because of water's high permittivity and electrical conductivity. Plane-wave attenuation is high compared to air and increases rapidly with frequency.

A company wants to build a new store. After reviewing the piece of land it is determined that a threatened woodpecker nests in that area .If the company is granted permission to build , what is the most environmentally responsible action by the company
Answer:
Explanation:
If the piece of land is forested or covered with many trees, the company can decide not to bring down all the trees (leaving some trees standing) and move as many as possible nests to the available trees within it's land. This will prevent emigration of the woodpeckers and can ultimately help conserve the woodpeckers in that land and indeed the area in which the land is situated.
This is most environmentally friendly because killing or scaring away of the birds by destroying there homes could lead to imbalance in the environment and even cause gradual extinction of the birds in the environment/area.
