A pine tree seed was produced by self-pollination. How many parents does this seed have?
A. one
B. two
The pine tree that produced the seed would be the only parent of a pine seed that was formed through self-pollination. So, the correct option is A.
What is Self-pollination?In the process of self-pollination, pollen from one flower or plant fertilizes the egg cells of another flower or plant. For self-fertilization to occur, both male and female reproductive components must be present within the same flower or plant.
The pollen from the male flower component, the anther, is carried to the female component, the stigma, during self-pollination either by the wind or by pollinators like bees, butterflies, or birds.
A pine tree that produces seeds will be the sole parent of pine seeds that form through self-pollination. Self-pollination occurs when pollen from the same pine tree fertilizes the pine tree's own egg cells, producing seeds with the genetic makeup of only one individual.
Therefore, the correct option is A.

What creates a bond dipole and how can you tell if a bond dipole exists?
Answer:
A dipole exists when there are areas of asymmetrical positive and negative charges in a molecule. Dipole moments increase with ionic bond character and decrease with covalent bond character.
Which element is more reactive? *
Cs
Rb
Answer:
Rubidium is a typical but very reactive member of the series of alkali metals. It is appreciably more reactive than potassium, but less so than caesium, and so would be expected to react more violently with those materials that are hazardous with potassium or sodium.
Answer:
Rb is more reactive .
Rubidium is the second most reactive metal and is very soft, with a silvery-white lustre.

Answer: The enthalpy change for formation of butane is -125 kJ/mol
Explanation:
The balanced chemical reaction is,
[tex]C_4H_{10}(g)+\frac{13}{2}O_2(g)\rightarrow 4CO_2(g)+5H_2O(l)[/tex]
The expression for enthalpy change is,
[tex]\Delta H=[n\times H_f{products}]-[n\times H_f{reactants}][/tex]
Putting the values we get :
[tex]\Delta H=[4\times H_f_{CO_2}+5\times H_f_{H_2O}]-[1\times H_f_{C_4H_{10}}+\frac{13}{2}\times H_f_{O_2}][/tex]
[tex]-2877=[(4\times -393)+(5\times -286)]-[1\times H_f_{C_4H_{10}}+\frac{13}{2}\times 0][/tex]
[tex]H_f_{C_4H_{10}=-125kJ/mol[/tex]
Thus enthalpy change for formation of butane is -125 kJ/mol

Suppose a fox population exists in an ecosystem. Some of the foxes maintain a heavy coat year-round, while others shed their heavy coat in the summer. Summers in this ecosystem
are becoming steadily hotter because of global warming. Which members of the species will most likely be able to adapt to the changing temperatures?
subject science
Answer:
The fox who shed their heavy coat in the summer.
Explanation:
If a fox has the ability to shed its coat in the summer, it will have no difficulties adapting to new temperatures even during winter. However, the heavy-coated one will.

Explain why it is necessary to use a mixture, alumina and cryolite, rather than just
alumina
Explanation:
The mixture of cryolite and aluminium oxide has a lower melting point than pure aluminium oxide. This means a lower amount of energy is required to establish effective conditions for electrolysis and thus makes it more cost effective.
What is the temperature range for our planet? Why is this important?
Answer:
are temperature range for are planet is -129 ⁰F (-18⁰C) that's the minimum.
+136⁰F (+58⁰C) this is the maximum surface temperature
Explanation:
"the planet is not too close or too far away from the sun, earth's atmosphere also plays a vital role is regulating the temperature by providing a blanket of gases that not only protects us from excessive heating and harmful radiation from the sun, but also traps heat rising from earth's interior core, keeping us warm"- Space.com

Which sets of elements have similar chemical and physical properties?
1. Mg and Ra 2. Al and P 3. Be and Ba 4. Na and Cl
1 & 2 ,
2 & 3
1 & 3
2 & 4
Answer:
1 & 3
Explanation:
Elements have similar chemical and physical properties if and only if they belong to the same group of elements in the periodic table.
A group of elements in the periodic table is a family of elements, the elements in the in the same group have the same number of valence electrons in their outermost shell, share similar chemical reactivity (with slight variation within the group) and similar physical properties (with slight variation within the group).
Magnesium, radium, beryllium and barium all belong to group 2 hence they have similar chemical and physical properties.
