Answer:
Covalent bond
Explanation:
The answer is covalent bond
A molecule of octane which is a component of gasoline contains covalent bonds.
Octane is a hydrocarbon compound, specifically an alkane, with the molecular formula C8H18. The structure you've provided illustrates the arrangement of carbon (C) and hydrogen (H) atoms in octane.
In octane, each carbon atom forms four single covalent bonds with other atoms (either carbon or hydrogen). Covalent bonds are formed when atoms share electrons to achieve a stable electron configuration. In the case of octane, carbon atoms share electrons with other carbon and hydrogen atoms to fill their valence electron shells, resulting in a stable and energetically favorable arrangement.
The structure of octane is a straight-chain alkane, with carbon atoms forming a chain and hydrogen atoms attached to the carbon atoms. The single covalent bonds between the atoms are represented by lines in the structural formula.
The shape of the molecule is determined by the arrangement of atoms and the types of bonds between them. In the case of octane, the single covalent bonds allow the carbon atoms to form a linear chain.
In conclusion, octane molecules are held together by covalent bonds, specifically single covalent bonds between carbon and hydrogen atoms. This type of bonding contributes to the stability and structure of the octane molecule, making it a major component of gasoline and contributing to its combustible properties.

"Blending" genes is associated with:
O Complete Dominance
O Blood Typing
O Incomplete Dominance
O Codominance
Answer:
a
Explanation:
The "blending" of genes is associated with incomplete dominance.
Incomplete dominance occurs when neither of the two alleles in a gene pair is completely dominant over the other.
Instead, the phenotype of the heterozygous individual is an intermediate blend or mixture of the phenotypes associated with each allele. In other words, the traits from both alleles are expressed in a blended or intermediate manner.
For example, in a cross between a red-flowered plant (RR) and a white-flowered plant (WW), if incomplete dominance is present, the resulting offspring (RW) may have pink-colored flowers, which represent a blend of the red and white traits.
Thus, the answer is incomplete dominance.

Which statement can be attributed to the discoveries made by Schwann?
A.All cells come from other cells.
B.All animals are made of cells.
C.All plants are made of cells.
D.
The smallest unit of life is the cell
The statement that can be attributed to the discoveries made by Schwann is as follows:
The smallest unit of life is the cell.Thus, the correct option for this question is D.
What is the contribution of T. Schwann?The major contribution of Theodore Schwann is that he proposed the Cell theory in 1839. This theory consists of three parts. They are as follows:
All living organisms whether plants or animals are made up of cells.A cell is the smallest unit of life for all living organisms. A Cell is the basic structural and functional unit of life.Apart from this, Cell theory was further refined by German Biologist Rudolf Virchow in 1855. He states that "all cells are arising from pre-existing cells". Option one is given by R. Virchow.
While all animals and plants are made up of cells is the second point of the cell theory. So, the correct option with respect to the question is that a cell is the smallest unit of life.
Therefore, the correct option for this question is D.

Which of the following was developed following Griffith's 1928 experiment. A. Some pathogenic bacteria cannot be heat-killed. Bacterial virulence is related to temperature resistance. B. Streptococcus pneumoniae causes disease. C. DNA from dead encapsulated bacteria can transform living un-encapsulated bacteria into living encapsulated bacteria. D. Dead encapsulated bacteria can cause disease.
Answer:
I believe A is the answer, but I'm not positive.
Explanation:
Griffith demonstrated in 1928 that the ability to synthesis a capsule and consequently become virulent can be transferred from heat-inactivated “smooth” strains to surviving but avirulent “rough” strains of S. pneumoniae. Therefore, option (A) is correct.
What was Griffith's experiment?British bacteriologist Frederick Griffith's 1928 bacteria experiment was the first to demonstrate the "transforming principle," which led to the realization that DNA serves as the carrier of genetic information.
Griffith tried injecting mice with heat-killed S bacteria as part of his investigations (that is, S bacteria that had been heated to high temperatures, causing the cells to die). Unsurprisingly, the mice were not harmed by the heat-killed S bacterium.
The first study demonstrating that bacteria are capable of transferring genetic information through a process known as transformation was conducted by Frederick Griffith.

in photosynthesis, water molecules are split into _______ and ______ atoms.
Answer:
1. hydrogen
2. oxygen atoms
Explanation:
Name a process in plants that uses oxygen. Compare the raw materials and products of this process with those of photosynthesis
Answer:
Cellular respiration uses oxygen. Comparisons below in explanation.
Explanation:
Plants do both photosynthesis and cellular respiration. They make their own food (photosynthesis) and break it down to make energy (cellular respiration). Cellular respiration uses oxygen, while photosynthesis doesn't (it is a product).
Photosynthesis has this as its general chemical equation:
[tex]6CO_2 +6H_2O[/tex] ⇒ [tex]C_6H_{12} O_6 + 6O_2[/tex]
Cellular respiration has this as its general chemical equation:
[tex]C_6H_{12} O_6 + 6O_2[/tex] ⇒ [tex]6CO_2 + 6H_2O[/tex]
As you can see, the raw materials of cellular respiration (glucose and oxygen) are the products of photosynthesis. The products of cellular respiration (carbon dioxide and water) are the raw materials used in photosynthesis.

Explain in your own words the difference between a leading strand and a lagging strand.
Answer:
So basically the primary distinction between the leading and lagging strands is that the leading strand is the DNA strand that develops continuously during DNA replication, whereas the lagging strand is the DNA strand that grows in small pieces known as Okazaki fragments. A leading strand is one that is produced in the 5'-3' direction, whereas a lagging strand is one that is formed in the 3'-5' direction. The leading strand is constantly produced where the other is not.

How does wood that is not burning differ from a nonflammable materials?
Wood is flammable, which means that it can burn when it is exposed to heat, oxygen, and an ignition source (such a spark or flame).
Thus, Nonflammable materials are those that do not readily ignite and do not burn even when exposed to high temperatures or flames.
Combustion Behaviour: During a fire, when wood is exposed to heat and oxygen, a combustion process takes place, releasing heat, light, and numerous combustion byproducts like carbon dioxide and water vapour.
The fire is maintained and can spread as a result of this procedure. Even when exposed to high heat or flames, nonflammable materials do not burn and do not support a fire.
Thus, Wood is flammable, which means that it can burn when it is exposed to heat, oxygen, and an ignition source (such a spark or flame).
