Unconformities occur when:
younger rock is placed on top of older rock
igneous structures cut across layered rock
eroded surfaces are covered by younger rock
an entire sedimentary bed is deposited at the same time
Answer:
The answer is: Eroded surfaces are covered by younger rocks.
Explanation:
The contacts between strata that do not occur underlying rocks in immediate order of age, or that do not fit together with them as part of a continuous whole, are called inconfonnities.
Thus an inconfonnity is a surface of erosion or non deposition that represents a significant hiatus, and separates younger strata from older rocks.
The answer is: Eroded surfaces are covered by younger rocks.

which influences both chemical weathering and mechanical weathering? iron plants tectonic plates wind
The correct option is A.
Plants can participate in both mechanical and chemical weathering of rocks. Mechanical weathering occurs when rocks are broken into smaller particles as the result of the roots of plants which grows and push them apart. Chemical weathering occur when the plant roots release chemicals, such as acids, which help in breaking down the rock particles.
What is the carbohydrate formed in photosynthesis?

The right option of this question is (C).
ExplanationPlants during the photosynthetic reaction, the energy and carbohydrates produce to maintain their life cycle. The photosynthetic system consists on two part as light-dependent an independent cycle. In the dependent cycle, the plants use the light to generate the energy compounds as ATP to start up the Independent cycle. The independent cycle also known as the Calvin Cycle, the environmental carbon dioxide is fixed to generate the carbohydrates. The most important carbohydrate that generates in this process is the glucose. The plant generates carbon dioxide and lactose is only present in milk.
So, the best option is (C) as glucose.

Why is light not a reactant or a product in photosynthesis?
Final answer:
Light is essential for photosynthesis as it powers the light-dependent reactions, but it is not listed as a reactant or product because light is a form of energy, not a substance that is consumed or produced in the reactions.
Explanation:
The subject of your question is photosynthesis, in which light plays a crucial role but is not listed as a reactant or a product. This is because light is a form of energy rather than a substance that combines chemically during photosynthesis. In the light-dependent reactions, light energy is harnessed by pigments within the chloroplasts and converted into chemical energy in the form of ATP and NADPH. These compounds are used in the Calvin cycle or light-independent reactions, to fix carbon dioxide into organic compounds like G3P.
While light is essential for the initial stage of photosynthesis, it does not get consumed or produced; instead, it acts as an energy source driving the synthesis of ATP and NADPH. These energy carriers then provide the necessary power for the light-independent reactions to produce carbohydrates from carbon dioxide. Therefore, while not listed as a reactant or a product, light is fundamentally indispensable for the overall process of photosynthesis.

B. water is split to drive NADP to NADPH conversion, and it is formed in the Calvin cycle
C. Glucose is formed right after the Calvin cycle
D. oxygen is released as a gas after water is split
PLEASE ANSWER ASAP!
GIVING OUT BRAINLIEST!!!
The right answer is C - Oxygen is released as a gas after water is split.
The second reactant here is H2O (water), and it reacts during electron transport chain of chloroplast.
In chloroplasts, light is used to oxidize water to oxygen, and to reduce NADP + to NADPH on the other hand, with concomitant proton injection into the lumen of thylakoids. In the mitochondria, oxygen is reduced to water while NADH is oxidized to NAD + and the succinate is converted to fumarate, with concomitant expulsion of protons out of the mitochondrial matrix.
Answer:
The second reactant is water and it comes from the root through absorption
The correct choice among the given options is option B, Water is split to drive NADP to NADPH conversion, and it is formed in the Calvin cycle
Explanation:
The second reactant in this equation is water and it comes from the root through absorption.
The water used in the process of photosynthesis is obtained from root which transport the water up to the leaves through the Xylem vessels. In the photosynthesis reaction the water molecule is splitted to produce hydrogen ion and free electrons after receiving the light energy from sun. The free electrons are then taken up by a carrier molecule NADP there by transforming it from NADP+ to NADPH. This step of stablisation of NADP+ to NADPH is a part of calvin cycle.

what is the photoreceptor that allows plants to detect day length called
The photoreceptor that allows plants to detect day length is called phytochrome.
Explanation:The photoreceptor that allows plants to detect day length is called phytochrome. Phytochrome is a protein covalently bonded to a light-absorbing pigment called a chromophore, and together they are known as a chromoprotein. Plants use the Pr/Pfr ratio of phytochrome at dawn to determine the length of the day/night cycle, allowing them to detect the change of season and adjust their physiology accordingly.
Final answer:
Phytochrome is the photoreceptor plants use to detect day length, aiding in photoperiodism, which is essential for recognizing seasonal changes and determining when to conduct crucial activities like flowering.
Explanation:
The photoreceptor that allows plants to detect day length is called phytochrome. Plants can sense the time of day and time of year by sensing and using various wavelengths of sunlight. The phytochrome molecules in plant leaves can convert between forms that absorb red light (Pr) and far-red (Pfr) light. At dawn, these molecules convert to the active Pfr form, which can remain in that form until sunset. At night, the Pfr slowly reverts to the Pr form. By measuring the ratio of Pr to Pfr at dawn, plants can determine if the nights are shorter or longer, which corresponds to different seasons.
Unfiltered sunlight is rich in red light, which is essential for the conversion process. Plants use this conversion to sense the change of season and exhibit photoperiodism, the reaction to the length of day or night. This is essential for crucial plant activities like flowering, setting winter buds, and vegetative growth. For instance, short-day plants flower when nights exceed a certain length, while long-day plants flower when the nights are shorter than a specific threshold.

By the end of mitosis, _______ cells are produced, whereas by the end of meiosis, _______ cells are produced. A. four; two B. two; four C. three; one D. one; three
By the end of mitosis, two cells are produced. whereas, by the end of meiosis, four cells are produced. Therefore, option B is correct.
What is meiosis and mitosis?There are two types of cell divisions and that is mitosis and meiosis. Mitosis takes place in all somatic cells, while meiosis division takes place in gametes.
Mitosis is also known as equilateral cell division, in which the parent cell is divided into two daughter cells and the genetic material such as chromosomes and DNA are duplicated and then transfer into two daughter cells. The number of chromosomes remains the same in the parent cell and daughter cell.
Meiosis occurs in gametes, in which the parent cell is divided into four daughter cells. It involves two rounds of division that ultimately result in four cells with only one copy of each chromosome. Hence, option B is correct.

Another component of acid rain is nitric acid, which forms when NO2, also a pollutant, reacts with oxygen and water according to the simplified equation 4NO2(g)+O2(g)+2H2O(l) → 4HNO3(aq) The generation of the electricity used in a medium-sized home produces about 14 kg of NO2 per year. Part A Assuming that there is adequate O2 and H2O, what mass of HNO3, in kg, can form from this amount of NO2 pollutant?
The mass of HNO3 will be 17.8 kg.
Further Explanation:
More than one element bonded together is known as a compound.Sum of total mass of molecule measure in gram which constitutes the atom of molecule known as molar mass. Gram per mole is an S.I. unit of molar mass.Molarity of a solution define as the number of moles of solute per litre solution.

Oxygen and water found in abundance. So, the NO2 is known as a limiting reagent as it is responsible for limiting the product formation. The moles of NO2is calculated with the help of the formula:
[tex]\begin{gathered}{\text{Number of moles=}}\frac{{{\text{given mass}}}}{{{\text{molar mass}}}}\hfill\\\begin{array}{*{20}{l}}{{\text{Given mass }}=14{\text{ kg}}=14000{\text{ grams}}}\\{{\text{Molar mass}}=46{\text{g/mol}}}\end{array}\hfill\\\end{gathered}[/tex]
Inserting the values in the formula,
[tex]\begin{aligned}{\text{Moles of N}}{{\text{O}}_2}=\frac{{14000}}{{46}}\\=304.34\end{aligned}[/tex]
By the help of Stoichiometry,
4 moles of NO2 will generate 4 moles of HNO3
This means that 304.34 moles of will generate,
[tex]\begin{gathered}=\frac{4}{4}\times304.34\hfill\\=304.34\hfill\\\end{gathered}[/tex]
In order to calculate the mass of HNO3, first equation can be used and we will get,

The mass of HNO3 that can form from the given amount of NO2 pollutant is 19.24 kg.
Explanation:To find the mass of HNO3 that can form from the given amount of NO2, we need to use stoichiometry and the balanced equation for the reaction.
From the balanced equation: 4 mol NO2: 4 mol HNO3
To convert the given mass of NO2 to moles, we need to divide by the molar mass of NO2:
14 kg NO2 * (1 mol NO2 / 46.0055 g NO2) = 0.304 mol NO2
Therefore, using stoichiometry, the 0.304 mol NO2 will react to form 0.304 mol HNO3.
To find the mass of HNO3, we can use the molar mass of HNO3:
0.304 mol HNO3 * (63.01284 g HNO3 / 1 mol HNO3) = 19.24 kg HNO3

which term describes the changes that occur in an organism during its lifetime
Final answer:
The changes that occur in an organism during its lifetime are described as development, which is part of an organism's life cycle and includes changes in size, form, and structure.
Explanation:
The term that describes the changes that occur in an organism during its lifetime is development. Development involves an organism changing in structure, form, and function as it progresses through various stages of its life cycle. This life cycle includes events such as gestation, birth, maturity, senescence, and death. Development is evident in the alterations in size, form, and structure that occur during an organism's lifespan. For instance, multicellular organisms typically start from a single cell that proliferates to many cells, which then stay together after dividing to produce a complex structure. These changes are part of an organized process that is controlled in some manner, and it's important to note that development in organisms can lead to not only growth but sometimes also a reduction in size and complexity, which may eventually result in the end of the organism's life.
