Answer:
H20 and light ( last choice)
The correct option is O CO2 and H2O.
In photosynthesis, light-dependent reactions occur in the thylakoid membranes of the chloroplasts. These reactions convert light energy into chemical energy in the form of ATP (adenosine triphosphate) and NADPH (nicotinamide adenine dinucleotide phosphate).
The input for the light-dependent reactions includes water (H2O) and light energy. Water molecules are split through a process called photolysis, releasing electrons, protons (H+ ions), and oxygen (O2) as byproducts. The electrons are then transferred through a series of electron carriers, generating ATP and NADPH.
While carbon dioxide (CO2) is involved in the subsequent light-independent reactions, also known as the Calvin cycle or the dark reactions, it is not directly an input for the light-dependent reactions. The Calvin cycle utilizes ATP and NADPH produced in light-dependent reactions, along with carbon dioxide, to synthesize glucose and other organic molecules.
Therefore, the input for the light-dependent reactions is CO2 and H2O, making option "CO2 and H2O" the correct choice.

Describe the term Continental Drift and seafloor spreading.
Continental drift is the theory that the Earth's continents have moved over geologic time relative to each other, thus appearing to have "drifted" across the ocean bed. The speculation that continents might have 'drifted' was first put forward by Abraham Ortelius in 1596.
Seafloor spreading is a process that occurs at mid-ocean ridges, where new oceanic crust is formed through volcanic activity and then gradually moves away from the ridge.
Answer:
Continental Drift-was a theory that explained how continents shift position
on Earth's surface.
Seafloor Spreading-helps explain continental drift in the theory of PLATE TECTONICS. when oceanic plates diverge, tensional plates causes fracture to occur in the lithosphere.

What kinds of substances cause the destruction of ozone?
Answer:
A lot of things, ranging from volcanic explosions to construction machines to cow farts. The biggest threat would be factories that are producing more than their share of emissions.
Explanation:
It's mainly because of the participants they're made of, and a big thing for the ozone is methane.
For the factories, it's because of the chemicals they put out. That's why they have emission limits.
Substances that destroy the ozone layer, known as ozone-depleting substances (ODS), include CFCs, HCFCs, halons, and other compounds that release chlorine and bromine. The release of these atoms into the stratosphere is a key factor in the depletion of the ozone layer, leading to increased UV radiation and associated health and environmental risks.
The substances that cause the destruction of ozone are primarily ozone-depleting substances (ODS) such as chlorofluorocarbons (CFCs), hydrochlorofluorocarbons (HCFCs), halons, methyl bromide, and carbon tetrachloride. These chemicals release chlorine and bromine atoms into the stratosphere, leading to the depletion of the ozone layer. When UV light in the stratosphere breaks apart these compounds, chlorine and bromine atoms are released, which can then destroy numerous ozone molecules. It is estimated that one chlorine atom can destroy over 100,000 ozone molecules before it is removed from the stratosphere. The Montreal Protocol is an international effort to phase out the production and use of these harmful substances to protect the ozone layer.
Ozone depletion results in higher levels of harmful ultraviolet radiation reaching the Earth's surface, which can lead to increased rates of skin cancer and eye cataracts in humans, and also negatively affect the environment by disrupting ecosystems, such as ocean food webs. Thanks to global agreements like the Montreal Protocol, the rate of ozone layer destruction has slowed, but continuous vigilance and adherence to these environmental policies is crucial to prevent further damage.
Ms. Huskey asked her science class to develop a scale model of the solar system where the sun has a diameter of 1.0 m given that the sun has a diameter of 1,392,000 km. How large should Shannon make the smallest planet in his scale model of the solar system?
Answer:
3.5 mm
Explanation:
Given the size of the sun, the scale ratio is :
[tex]\dfrac{1m}{1,392,000km}[/tex]
Now to determine how large the smallest planet should be, you just need to make sure that its measurement is proportion to that scale. According to your table, the smallest planet is Mercury with a diameter of 4,879.4 km. Now we can write a proportion for this, to determine the scale:
[tex]\dfrac{1m}{1,392,000km}=\dfrac{x}{4,879.4km}[/tex]
Cross multiply then divide to solve for x.
[tex]\dfrac{1m\times 4,879.4}{1,392,000km}=x\\\\\dfrac{4,879.4m}{1,392,000}=x\\\\0.00350m=x[/tex]
So the smallest planet would be 0.0035m. Since your choices are in mm (and that is a very small number to estimate) we can convert it into mm.
1 meter = 1,000 millimeters
[tex]0.0035m\times\dfrac{1,000mm}{1m}=3.5mm[/tex]
The answer is then 3.5mm.
To maintain the scale proportion, if the sun is 1m in diameter in the model, Shannon should make the smallest planet, Mercury, 3.5 mm in diameter.
Explanation:The smallest planet in our solar system is Mercury, which has a real diameter of approximately 4,879 km. Given that the Sun's real diameter is 1,392,000 km, to find out how large Shannon should make Mercury in his scale model of the solar system, we have to keep the proportions the same.
To achieve this, we need to set up a proportion using real-life sizes and scale sizes. In this case, the proportion would be (4,879 km / 1,392,000 km = x / 1 m), with 'x' being the diameter of Mercury in the model. Solving for 'x', we get x = (4,879 km / 1,392,000 km) * 1 m, which equals approximately 0.0035 m, or 3.5 mm. Therefore, in Shannon's model, if the Sun is 1m in diameter, the smallest planet, Mercury, should be 3.5 mm in diameter.

one way meiosis I is different from mitosis is that
a. meiosis I produce 2 haploid daughter cells, but mitosis produces 2 diploid daughter cell
b. sister chromatids are pulled apart during meiosis I, but not during mitosis
c. replication occurs during interphase before mitosis, but not before meiosis I
d homologous chromosomes are segregated during mitosis, but remain together during meiosis I.
Answer:c
Explanation:
Final answer:
Meiosis I differs from mitosis in that it produces two haploid cells with genetic variation due to homologous chromosome pairing and crossover, whereas mitosis produces two genetically identical diploid cells without these features.
Explanation:
One way meiosis I is different from mitosis is that meiosis I produce 2 haploid daughter cells, while mitosis produces 2 diploid daughter cells. This is because meiosis involves two rounds of nuclear division, resulting in cells with half the number of chromosomes as the parent cell. In contrast, mitosis is a single division that results in daughter cells that are genetically identical to the parent cell. Additionally, in meiosis I, homologous chromosomes are paired and crossover occurs, which is not seen in mitosis.
During meiosis I, synaptonemal complex binds homologous chromosomes. Chiasmata form, allowing crossover between nonsister chromatids, resulting in genetic variation in the daughter cells. These chromosomes line up as tetrads on the metaphase plate, with spindle fibers attached to kinetochores of homologous chromosomes, a process unique to meiosis I. Meanwhile, mitosis does not feature these events and maintains the diploid state without genetic recombination.
The location of the water table is subject to change.
Please select the best answer from the choices provided
OT
OF
Answer:
The location of the water table is subject to change.- True ( first choice)
The water table, which is not fixed, can change location based on several factors. These factors include precipitation amounts, human water usage, and environmental changes. This changing location of the water table is pertinent to hydrology, water management, and environmental conservation.
Explanation:Yes, the location of the water table is indeed subject to change. This is due to the fact that the water table isn't fixed, but varies in response to several factors. These include rainfall, the amount of water used by people, and changes in the environment. For example, during periods of heavy rain, the water table may rise as more water soaks into the ground. Conversely, during times of drought, or when humans extract large quantities of groundwater, the water table may fall. This variability of the water table location is an important aspect to consider in fields such as hydrology, water management, and environmental conservation.

An atom of element A has 23 protons. What would the element's atomic number be?
Answer:
23
Explanation:
The atomic number is determined by the number of protons.
The atom of element A would have an atomic number of 23 since the atomic number is equivalent to the number of protons in an atom's nucleus.
This number defines the chemical element and determines its identity. By comparison, uranium has an atomic number of 92 and thus, 92 protons.
Explanation:An atom of element A with 23 protons would have an atomic number of 23. This is because the atomic number is defined as the number of protons in an atom’s nucleus, and it uniquely identifies the chemical element.
For example, any atom with 6 protons is known as carbon and has an atomic number of 6. An element's atomic number also tells you the number of electrons in a neutral atom of that element.
In relation to other elements, the atomic number of uranium is 92, indicating it has 92 protons. For an isotope of uranium with a mass number of 235, the number of neutrons would be the mass number minus the atomic number, which is 235 - 92, equating to 143 neutrons.

Explanation:
This process occurs in the ribosomes. As the ribosome reads the codons on the mRNA the corresponding tRNA with the complementary anticodon is recruited. The tRNA brings in an amino acid (attached to it), and the amino acid is joined to the rest of the growing polypeptide chain. Each codon/anticodon specifies for a specific amino acid.
how do organisms grow
Hello! My name is Zalgo and I am here to help you out on this amazing day. Organisms grow, but only certain organisms are capable of growing. The meaning of growing is "to get bigger/expand" and the way that multicellular cells grow is by making more cells. Plants also have special tissues called "Meristems" where the growing process happens. Single celled organisms (unicellular organisms) increase their numbers by "dividing" and making more cells like themselves.
