Elements in the same column of the periodic table of the elements all
A. have the same number of protons.
B. share the same atomic structure.
C. have similar physical characteristics.
D. share the same number of neutrons
Answer:
C
Explanation:
elements in the same column have different number of protons and different number of neutrons.
Elements in the same column of the periodic table of elements all share the same atomic structure. Thus, the correct option for this question is B.
What is the similarity in the elements that belong to the same column?Each column is called a group. The elements in each group have the same number of electrons in the outer orbital. Those outer electrons are also called valence electrons. They are the electrons involved in chemical bonds with other elements.
The number of protons governs the atomic number of an element. So, elements never have the same number of protons. The number of neutrons along with protons governs the atomic mass of an element which also never remains the same.
The physical characteristics of any element depend on the majority of the attributes. So, it may also vary from element to element.
Therefore, elements in the same column of the periodic table of elements all share the same atomic structure. Thus, the correct option for this question is B.

Explain incomplete dominance, using snapdragon
flowers as an example.
Answer:
Dominant allele does not completely conceal recessive allele.
Snapdragon with genotype Rr (R being red and r being white), would have a phenotype of pink flowers.
Explanation:
Incomplete dominance is where a dominant allele is not able to completely conceal a recessive allele, usually leading to a phenotype which appears to be a combination of the two.
For example, in snapdragons:
The allele for red flowers (R) is dominant over the allele for white flowers (r). Let's say a snapdragon flower had the genotype Rr, one allele for red flowers and one for white. In the case of 'normal' dominance the dominant red flower allele (R) would mask the effects of the recessive white flower allele (r), resulting in the phenotype (outward observable characteristics) of having red flowers.
However here in the case of incomplete dominance, the dominant allele would not be able to fully cover up the effects of the white flower allele, meaning that both colors (red and white) are expressed in the phenotype, resulting in pink flowers.
Hope this helped!
Answer:
Incomplete dominance is seen in offspring that have a third phenotype not seen in the parents. Snapdragons are an example. The third phenotype results when a snapdragon with the red pigment protein crosses with a snapdragon with a defective gene that produces no pigment, resulting in a white snapdragon. The offspring receive one allele from each parent, resulting in half the amount of pigmentation for red color being expressed. The offspring will be pink snapdragons instead of red or white.

Explain how ocean temperatures affect the climate of coastal cities.
Answer:
Explanation: Warm ocean currents heat the air above the water and carry the warm air to the land, increasing the temperature of the coastal region. The same is true for cold ocean currents, except that they carry cooler air to the land and lower the temperatures of the coastal region.
Answer:
Warm and cold ocean currents can influence coastal climate, but only when local winds come in from the sea. Warm winds heat the air over the ocean, causing temperatures to rise over land. Cold currents will cool the air and add cooler temperatures to the land.

Gaining Insight into Depositional Environments of Sedimentary Rocks
Name: ________ Course:____________
Section:_______ Date:_____________
Sedimentary structures, fossils, cements, and other features of sedimentary rocks provide insight into the environment in which the sediment was deposited.
Match each of the features in the left-hand column to an aspect of the depositional environment listed in the right-hand column by placing the corresponding letter in the proper blank.
Rock and/or feature of the rock
(a) poorly sorted arkose
(b) contains fossils of intact coral
(c) red mudstone containing dinosaur footprints
(d) black shale containing some pyrite crystals
(e) sandstone containing symmetrical ripples
(f) cross-bedded sandstone
(g) contains > 50% carbon and fossil leaves
(h) contains large, rounded pebbles and cobbles (contains fossils of feathers G very angular grains
Aspect of the depositional environment
1. deposited in a desert dune or in a current
2. formed from sediments accumulated in a swamp
3. deposited in very quiet (stagnant) water
4. deposited in an anoxic marine setting
5. deposited by a swiftly moving stream
6. formed from warm-water, shallow marine reef
7. has not undergone a lot of transport immature,
8. deposited close to the source
9. formed from terrestrial mud (riverbank deposits)
10. deposited on a beach
Answer:
(a): 7. and 8.
(b): 6.
(c): 9.
(d): 4.
(e): 10
(f): 1.
(g): 2.
(h): 5. and 3.
Explanation:
Sedimentary rocks are rocks generated from pre-existing rocks and/or once-living organisms. Arkose is a type of sandstone rich in feldspar (at least 25% of this mineral). Moreover, a rock containing coral fossils indicates that its depositional environment was located in warm tropical reef waters. Mudstone is a kind of sedimentary rock composed of clay (in this case, sediments continued to be deposited above the dinosaur footprints). The black shales are fine-grained sedimentary rocks composed of a mixture of clay (in this case, the pyrite crystals are used as an indicator of low oxygen). Symmetrical ripple marks in the sandstone indicate a marine environment where water motion was dominated by wave oscillations. Cross-bedding is a common structure of sedimentary rocks that form during deposition on inclined surfaces of bedforms (e.g., ripples and dunes). Sediment deposition in swamps is usually heavily vegetated and therefore they are rich in organic matter, while deeper swamp sediments are generally anoxic. Finally, cobblestones are naturally occurring cobble-sized stones formed from the flow of water and gathered from stream beds, while pebblestones are formed when water bodies hit the giant rocks in the rivers and lakes.

Answer:
will you msg me in I.nstagram
11. The balanced chemical reaction is:
2 B(IO₃)₃ + 3 Fe₃P → 2 BF₃ + 3 Fe(IO₃)₂
12. In this case, the limiting reagent is the Iron (II) phosphide.
13. The amount of Iron (II) iodate produced is 1.825 moles.
14. The amount of excess Boron iodate remaining after the reaction is 0.265 moles.
15. The actual yield of the reaction is 132.1 g.
11. To write the balanced chemical reaction, we need to first determine the correct coefficients for each reactant and product. We can do this by balancing the number of atoms of each element on both sides of the equation.
12. The limiting reagent is the reactant that is used up first. In this case, the limiting reagent is the Iron (II) phosphide. This is because 112.0 g of Iron (II) phosphide is equivalent to 0.560 moles, which is less than the 1.825 moles of Boron iodate.
13. To calculate the amount of Iron (II) iodate produced, we need to multiply the number of moles of Boron iodate by the molar ratio between Boron iodate and Iron (II) iodate.
14. The amount of excess Boron iodate remaining after the reaction is 0.265 moles. This is because 1.825 moles of Boron iodate minus 0.560 moles of Iron (II) phosphide is equal to 0.265 moles.
The amount of excess Iron (II) phosphide remaining after the reaction is 56.0 g. This is because 0.560 moles of Iron (II) phosphide is equal to 56.0 g.
15. To calculate the actual yield of the reaction, we need to multiply the theoretical yield by the percentage yield.
The actual yield of the reaction is 132.1 g. This is because 1.825 moles of Boron iodate is equivalent to 132.1 g and the percentage yield is 72.659.
