Sally likely chose trees and cotton as the two renewable resources because they are both natural materials that can be replenished relatively quickly through natural processes or human cultivation, unlike oil, gold, and iron.

Sally likely had D) trees and cotton in mind as the two renewable resources on the list. Here's why:

Trees: The image clearly shows that trees are a natural resource used to make paper, furniture, homes, and even fuel. Trees are considered renewable because they can be replanted and grown relatively quickly compared to other resources like oil or metals.

Cotton: Cotton is also listed as a natural resource used for clothing and paper. Cotton plants are renewable because they can be harvested and replanted annually.

The other options are less likely to be considered renewable for the following reasons:

Oil and gold: Oil and gold are both fossil fuels and minerals, respectively, which means they were formed millions of years ago from organic matter or geological processes. They are not readily replaceable within human timeframes and are therefore considered non-renewable resources.

Iron: Iron is also a non-renewable resource as it is mined from the earth and its formation takes millions of years. While it can be recycled to some extent, it's not easily replaced in its natural form.

Therefore, based on the information provided in the image and the definition of renewable resources, trees and cotton are the most likely candidates that Sally would have identified as renewable on the list.

it's called a codon. it will become an aminoacid later on, in the ribosome

A linear code of 3 sequential bases on a DNA molecule is called a codon. These codons form the genetic code, with each one corresponding to a specific amino acid in a protein. The two strands of the DNA molecule are complementary, with certain bases always pairing together.

A linear code of 3 sequential bases on one side of a DNA molecule is referred to as a codon. Each codon corresponds to a specific amino acid in a protein. DNA uses four bases: adenine (A), thymine (T), cytosine (C), and guanine (G).

The two strands of the DNA molecule are complementary to each other, with adenine always pairing with thymine, and cytosine always pairing with guanine. For instance, if one strand of DNA has the sequence ATC, the complementary sequence on the opposite strand would be TAG.

These sequences of codons on DNA are translated into mRNA sequences (the process of transcription), which in turn are translated into proteins (the process of translation). This progression of information from DNA to mRNA to proteins is known as the 'Central Dogma' of molecular biology.

Answer:

High-low-diffusion

Explanation:

The transport of molecules may occur from the region of the high concentration to the reign of lower concentration or vice-versa. The different transport process are diffusion, osmosis and active transport.

Diffusion may be defined as the movement of the particles to the lower concentration from its region of the higher concentration. The molecules moves towards the concentration gradient. The diffusion occurs naturally in the cells and does not require energy for its transport.

Thus, the correct answer is option (a).

Molecules naturally spread from areas of high concentration to areas of low concentration. This process is called diffusion and does not require energy. The process where molecules move from low to high concentration is called active transport and it requires energy.

Molecules naturally spread from areas of high concentration to areas of low concentration through a process called diffusion. This process is described by the principle of diffusion in biology which dictates that molecules tend to spread out evenly in an available space. This movement happens passively, meaning it does not require energy, making option a) high-low-diffusion the correct answer.

On the other hand, active transport refers to the movement of substances against a concentration gradient (from low to high concentration), and this process requires energy. Passive transport refers to the natural movement of substances along a concentration gradient (from high to low concentration) without the use of energy. The understanding of these principles is crucial in biology particularly in the study of cell processes.

The cytoplasm interacts with cellular components by housing organelles, supporting metabolic reactions, engaging in protein synthesis, and maintaining cellular structure through the cytoskeleton. Its composition facilitates chemical reactions and plays a crucial role in cell-cell communication and the cell's metabolic processes.

Explanation:

Interaction of Cytoplasm with Other Cellular Components

The cytoplasm plays a crucial role in the life of a cell by serving as the medium where most cellular activities occur. It is a gel-like substance composed primarily of water, salts, and a high concentration of macromolecules. This composition provides a viscous environment that facilitates a variety of chemical reactions and interactions essential for the cell's survival and function.

The cytoplasm interacts with various cellular components in several ways:

Furthermore, the cytoplasm is pivotal in cell-cell interactions, providing a platform for cellular signals that guide cells to their correct positions within an organism and drive their differentiation into specialized forms. Calcium ion movements within the cytoplasm serve as signals for various metabolic processes, indicating the cytoplasm's integral role in intracellular communication.

In summary, the cytoplasm essentially serves as the site for most cellular activities by providing a supportive environment for organelles, facilitating metabolic reactions, and playing a central role in cellular communication and structural integrity.

MtDNA is beneficial for DNA typing because it can be analyzed with smaller samples, is useful when nuclear DNA is degraded, is inherited only from the mother, and has a high mutation rate that aids in tracking evolutionary history.

Unlike nuclear DNA, which requires larger samples and contains genetic information from both parents, mtDNA can be useful even when the nuclear DNA is degraded and requires a much smaller sample for analysis. Since mtDNA is inherited maternally, it is present in all maternal relatives and lacks recombination, making it ideal for tracking matrilineal descent. A notable feature of mtDNA is its relatively high mutation rate, which is vital for understanding evolutionary history and for the identification of matrilineal ancestry, even connecting living people to distant ancestors through shared maternal lineage.

Answer:

Nucleic acids are of two types DNA and RNA which are made up of monomeric units called nucleotides.

One monomer is one nucleotide which further consists of three parts:

1: Nitrogenous base

2: Sugar (a ribose sugar in RNA and a deoxyribose sugar in DNA)

3: Phosphate group

Explanation:

If we talk about single strand of nucleic acid DNA or RNA, there is a phosphodiester linkage that holds monomers together in a strand of nucleic acids. This phospho di ester linkage is formed when a condensation reaction occurs between a hydroxyl group of two sugars and a phosphate group.

You can see a better representation in attached figure.

Hope it help!

In a single strand of nucleic acid, the monomers (nucleotides) are held together by phosphodiester bonds. These create a sugar-phosphate backbone with protruding nucleotide bases. The bases can pair with others to form a double helix structure via weaker hydrogen bonds.

The monomers of a single strand of nucleic acid, known as nucleotides, are held together in a chain by phosphodiester bonds. These bonds occur between the 5' phosphate group of one nucleotide and the 3' hydroxyl group of the next nucleotide, linking them together to form a long polymer or chain. This bonding creates a sugar-phosphate backbone for each single strand of DNA, where the nucleotide bases protrude.

Various nucleotides are used in this process, including adenine, thymine, cytosine, and guanine in DNA, and these form a double helix structure when two such strands are attached at their protruding bases via millions of hydrogen bonds. This structure can easily unzip down the middle, due to the relatively weaker hydrogen bonds compared to the strong covalent bonds in the phosphodiester bonds, allowing both strands to function as templates for replication.

Answer:

B) releases energy.

Explanation:

Cellular respiration is a process in which organic molecules are oxidized and the production of ATP (adenosine triphosphate) occurs, which is used by living beings to meet their energy needs, ie respiration is a biochemical process that results in the release of energy. Breathing occurs in three basic steps: glycolysis, the Krebs cycle, and oxidative phosphorylation.

The squirrel gets energy from eating its diet. When the hawk eats it, that energy is transferred from the squirrel into the hawk. Nutrients the hawk needs gets absorbed into the bloodstream through arteries and veins in the stomach to the brain, and these nutrients can be turned into amino acids, with help grow necessary things on your body, such as hair, nails, or, in this case, feathers and claws. Any unneeded matter is flushed out of the body in the form of waste.

The hawk gains energy by digesting the squirrel. The indigestible matter from the squirrel is excreted, and returns to the ecosystem, where it can be used by other organisms.

When a hawk swoops down and catches a squirrel, the hawk acquires energy by metabolizing the squirrel's body mass through digestion. This energy is utilized by the hawk for its various physiological activities such as flight, hunting, and reproduction. However, the squirrel's body also consists of matter that is not digestible or usable by the hawk. This indigestible matter, primarily consisting of bones and fur, is excreted by the hawk, returning it to the ecosystem where it may be further broken down by decomposers into simpler nutrients that can be used by plants and other organisms in the food chain. Therefore, while a portion of the matter in the squirrel provides energy to the hawk, the rest of the matter is recycled back into the ecosystem.

Final answer:

The molecules in the food consumed by a squirrel are converted to energy and other types of molecules through the process of cellular respiration.

Explanation:

When a squirrel consumes acorns for food, the molecules in the food are not eliminated completely, nor are they destroyed in the animal's body. Instead, these molecules undergo a biochemical process known as cellular respiration. During cellular respiration, the organic molecules originally produced by plants, like sugars, are converted into energy that the squirrel's body can use for various life processes. Additionally, these molecules are transformed into other types of molecules that are necessary for the squirrel's growth and maintenance. So the correct answer is B. The molecules get converted to energy and other types of molecules.
