If a reaction equation is balanced, then___.
Select all that apply.
A. it will follow the law of conservation of mass
B. There will be coefficients written in front of the formulas
C. The mass of products will be equal to the mass of the reactants
D. The mass of the products will be greater than the mass of the reactants.
If a reaction equation is balanced, it will adhere to the law of conservation of mass, showing equal mass for reactants and products, and balanced with coefficients in front of the chemical formulas. The correct option is A.
If a reaction equation is balanced, then several things hold true based on the principles of chemistry. Firstly, it will follow the law of conservation of mass. This fundamental law states that mass cannot be created or destroyed in a chemical reaction. Consequently, the total mass of the reactants must equal the total mass of the products. Secondly, you will find coefficients written in front of the formulas to indicate the relative amounts of each substance necessary to balance the equation.
Subsequently, the mass of the products will be equal to the mass of the reactants. This is a direct consequence of balancing the equation. It's not correct that the mass of the products will be greater than the mass of the reactants, as this would violate the law of conservation of mass.

What are the end products of the light-dependent reactions that need the presence of light to occur?
A. ATP and NADPH B. Oxygen, ADP, NADP+ C. Phosphorus, sugar, ADP D. Carbon dioxide, nitrogen, ATP
Answer:
A
Explanation:
The light energy from sunlight in photosynthesis is used to split the water molecule into H+ and O2-. The H+ is then used to reduce NADP+ to NADPH. Through photophosphorylation, the energy from the sun is also used to make ATP from ADP. As the electrons are passed from one protein to the other in the chain, the energy released is what is used to create ATP.
Oxygen is evolved out as a byproduct
NADP+ + 2e- + 2H+ --> NADPH + H+
The ondes that need the presence of light to occur are A. ATP and NADPH
What are the end products of the light-dependent reactions that need the presence of light?The end products of the light-dependent reactions in photosynthesis, which require the presence of light, are ATP (adenosine triphosphate) and NADPH (nicotinamide adenine dinucleotide phosphate). These products serve as energy carriers that are subsequently used in the light-independent reactions (also known as the Calvin cycle) to produce carbohydrates.
Option B is incorrect because oxygen is produced as a byproduct of the light-dependent reactions, not as an end product that is utilized within the process. ADP (adenosine diphosphate) and NADP+ (nicotinamide adenine dinucleotide phosphate) are converted to ATP and NADPH, respectively, during the light-dependent reactions.
Option C is incorrect because phosphorus and sugar are not the primary end products of the light-dependent reactions. While the production of sugars occurs during the light-independent reactions, phosphorus is not directly involved in the light-dependent reactions.
Option D is incorrect because carbon dioxide and nitrogen are not end products of the light-dependent reactions. Carbon dioxide is utilized in the light-independent reactions to synthesize sugars, and nitrogen is typically not directly involved in the light-dependent reactions of photosynthesis.

During the Carboniferous period, plants and animals grew very large due to high concentration of A. oxygen in the atmosphere. B. nitrogen in the atmosphere. C. carbon dioxide in the oceans. D. argon in the oceans .
Answer:
Option A, oxygen in the atmosphere
Explanation:
The highest level of oxygen reached during this phase of the geological cycle of earth. The oxygen level in Carboniferous period accounted for 35% as compared to 21% of oxygen in the atmosphere in present time.
Due to high oxygen content, the giant and wide varieties of terrestrial animal and plant species evolved. For example – size of insects and carwlies increased, plant became extremely giant, increase in number of tree ferns etc.
During the Carboniferous period, plants and animals grew very large due to high concentration of oxygen in the atmosphere and the correct option is option A.
The Carboniferous period is a geologic period and system that spans from 358.9 to 298.9 million years ago in the Paleozoic Era. It is named after the Latin word "carbo", meaning coal, as this period saw the formation of large coal deposits. The Carboniferous period is also known as the "Age of Amphibians" due to the dominance of these animals on land.
During the Carboniferous period, the Earth's continents were slowly coming together to form the supercontinent Pangea. This led to a warm and humid climate, which was ideal for the growth of swamp forests. These forests were home to a wide variety of plants and animals, including amphibians, reptiles, and insects.
Thus, the ideal selection is option A.

Describe an environmental factor that could influence natural selection and decrease genetic diversity
Answer:
Availability of sunlight.
Explanation:
Some living organisms need a lot of sunlight to survive and cannot stand living in the shade, as is the case with some plants. In this case, the availability of sunlight presents itself as an environmental factor that will influence natural selection, because with less availability of sunlight, the less adapted organisms will die and the more adapted organisms will resist and pass this trait to their descendants.
Natural selection tends to decrease genetic variability because only a few genotypes will be selected. In addition, it also contributes to the permanence of a certain characteristic in the population.
The process of being selected by the nature to survive in the current condition is called natural selection. Only those species can be naturally selected who are ready to change and adapt themselves according to environmental needs.
These are the factors that support natural selection.
ReproductionRecombinationCrossing overMutationMany species are not able to mate with the other species due to geographical barriers and also not being able to migrate to other habitats.
For example- Australia is separated from the other continents, the marsupials are only restricted to the specific landmass and are not able to mate with other animals from other countries.
Increases in temperature harm cold-blooded animals. They can not able to maintain the normal body temperature and lead to the death
Therefore, The factors which affect natural selection are geographical barriers and a rise in temperature.

the offspring of two diferent species ,such as a liger :
I think the answer you’re look for is (a) hybrid
A hybrid is the offspring of two different species and is often infertile due to differences in genetic instructions from each parent. The ability of species or hybrids to reproduce and the fitness of the offspring can impact species evolution over time. Being part of the same species is defined by the ability to breed and produce fertile offspring.
Explanation:The offspring of two different species, such as a liger, are referred to as a hybrid. Hybrids are produced when individuals from two separate species interbreed. Often, these hybrids are infertile, meaning they cannot produce offspring themselves. This is due to differing genetic instructions from each parent species, which may interfere with the development of viable offspring. This characteristic of infertility among hybrids is noticeable in the example of a liger, a hybrid between a lion and a tiger.
However, there are situations where the hybrid offspring are more fit than the parents. In such circumstances, reproduction could continue between the species and the hybrids, potentially leading to a merging of the two species. The fit of hybrid creatures compared to their parents can impact how species evolve over time.
It's worth noting that being part of the same species is normally defined by the ability to breed and produce fertile offspring. Therefore, although two organisms may appear similar or even virtually identical, such as bald eagles and African fish eagles, they are confirmed as separate species due to their inability to produce fertile hybrids.

What monomers are carbohydrates made of
monosaccharides, disaccharides, polysaccharides
Final answer:
Carbohydrates are made of monomers called monosaccharides, which include hexose sugars like glucose, fructose, and galactose, as well as pentose sugars like ribose and deoxyribose.
Explanation:
Carbohydrates, commonly known as saccharides, are made up of monomers called monosaccharides. The simplest form of carbohydrates, monosaccharides are single sugar units that can join together to form more complex carbohydrates.
The most common monosaccharides include the hexose sugars like glucose, fructose, and galactose, all of which contain six carbon atoms. Additionally, there are pentose sugars such as ribose and deoxyribose, which contain five carbon atoms and are found in the nucleic acids DNA and RNA.
These monosaccharides are the basic building blocks for more complex carbohydrates like disaccharides, which consist of two monosaccharide units, and polysaccharides, which are polymers made up of countless monosaccharide monomers bonded together through a process called dehydration synthesis. The reverse process, hydrolysis, breaks polymers back into monomers.

The incorrect step in the rock cycle is 'Sediments melt deep beneath Earth's surface' because sediments do not melt to form magma; solid rocks do when subjected to high heat.
The step in the rock cycle which is not correct is: D. Sediments melt deep beneath Earth's surface. During the rock cycle, sedimentary rocks, igneous rocks, or metamorphic rocks may be subjected to heat and pressure to become metamorphic rocks, or they may melt to form magma.
However, it is not sediments that melt to form magma; rather, it is existing solid rocks that melt due to high heat.
In the rock cycle, sedimentary rocks are typically formed when rocks on Earth's surface break down into small pieces that are then compacted and cemented together. Igneous rocks form when magma or lava cools and hardens.
Metamorphic rocks are created when existing rocks are subjected to great heat and pressure, but without melting. These processes are continuous and over time, rocks can transform from one type to another, driven by Earth's geological forces.
