Explanation:

During cellular respiration, glucose and oxygen are converted into carbon dioxide and water, and the energy is transferred to ATP. :)

Answer:

Cells do not use the energy from oxidation reactions as soon as it is released. Instead, they convert it into small, energy-rich molecules such as ATP and nicotinamide adenine dinucleotide (NADH)

Explanation:

In a complex carbohydrate molecule, the ratio of carbon to hydrogen to oxygen is 1:2:1. Therefore, if there are 12 carbon atoms, there will be 24 hydrogen atoms and 12 oxygen atoms.

Given that carbohydrates can be represented by the stoichiometric formula (CH₂O)n, where n is the number of carbons in the molecule, the ratio of carbon to hydrogen to oxygen in carbohydrate molecules is 1:2:1. Thus, if a molecule of a complex carbohydrate is made of 12 carbon atoms, the number of hydrogen atoms will be 2*12 = 24, and the number of oxygen atoms will be 1*12 = 12. This is because for every one carbon atom, there are two hydrogen atoms and one oxygen atom.

Answer:

D

Explanation:

Since Adenine (A) pairs with Uracil (U) in RNA, Thymine(T) pairs with Adenine but Adenine doesn't pair with Thymine in RNA and Guanine(G) and Cytosine(C) then the nitrogenous pairs would be like this.

GCATTA

CGUAAU

The corresponding mRNA strand would be: CGUAAU. Therefore, option (D) is correct.

mRNA stands for messenger RNA. It is a type of RNA molecule that carries genetic information from DNA to the ribosomes, where it serves as a template for protein synthesis. mRNA is transcribed from DNA during the process of gene expression and is crucial for protein production in cells.

To determine the strand of mRNA produced from a given strand of DNA, we need to apply the complementary base pairing rules. In DNA, the bases are adenine (A), thymine (T), cytosine (C), and guanine (G). In RNA, however, thymine is replaced by uracil (U). The complementary base pairs are A-T and G-C in DNA, and A-U and G-C in RNA.

Given the DNA strand: GCATTA

To transcribe it into mRNA, we replace each DNA base with its complementary RNA base:

G -> C

C -> G

A -> U

T -> A

T -> A

Therefore, the corresponding mRNA strand would be: CGUAAU

Answer:

Replication

Explanation:

When DNA is copied the process is called replication since the DNA is being copied.

Individual organisms do not evolve; instead, evolution is a process that occurs across generations within a population. While individual organisms can adapt to their environment, these adaptations do not equate to evolution. Examples of evolution include the genetic changes leading from pre-humans to modern humans.

Can an individual organism evolve? No, an individual organism itself cannot evolve. Evolution is a process that occurs over many generations within a population, not within the lifespan of a single organism.

When we talk about evolution, we refer to the genetic changes that accumulate in a population over time. These changes can lead to new species, but they do not alter the genetic makeup of an individual once it is born.

Examples of Evolution

For instance, consider the transformation from pre-humans to modern humans (Homo sapiens). This was not a change that occurred in a single individual but rather a series of genetic adaptations across countless generations.

Adaptations vs. Evolution

It's important to differentiate between an organism adapting to its environment and evolution. An individual organism can adapt by developing better skills for survival, but this adaptation is not the same as evolution. Evolution requires the genetic changes that happen across multiple generations, leading to the emergence of new species.

Organisms interact with their environment, which can influence their success and survival.

Populations, not individuals, evolve over time through the accumulation of genetic changes.

Examples of evolution include the transition from dinosaurs to birds and pre-humans to modern humans.

Specific heat means the heat required to raise the temperature of the unit mass of a given substance by a given amount (usually one degree).. The specific heat of water is high (1 calorie/gm/°C). This property ensures slow heating of water; maintain constant temperature of living organisms and environment.

Expansion upon freezing  is what causes ice to be less dense as a solid than as a liquid. This means that ice floats in liquid water. Hydrogen bonding is the source of this rare property. Water freezes when its molecules are no longer moving around enough to break their hydrogen bonds.even though it doesn't seem  like a very important property, but the fitness of the environment would drastically change if water were less dense than ice. All of bodies of water would eventually freeze over if ice did sink, making life on Earth impossible.

Versatility as a solvent Water is called the "universal solvent" because it dissolves more substances than any other known liquid. This is important to every living thing on earth. It means that wherever water goes, either through the ground or through our bodies, it takes along valuable chemicals, minerals, and nutrients.

Regulation of amino acids

When amino acids are absorbed by liver cells a series of chemical reactions begins. ... The amine group is reduced to ammonia by the addition of a hydrogen atom. This process is called deamination. The non-nitrogenous portion of the molecule is converted to carbohydrates or fats.

Explanation:

Gene therapy is intended to acquaint hereditary material into cells in order to compensate for faulty or mutated genes or to make a helpful protein.

On the off chance that a faulty gene makes a beneficial protein be flawed or missing, gene therapy might have the option to present a typical duplicate of the gene to reestablish the function of the protein.  

A gene that is embedded straightforwardly into a cell as a rule doesn't work. Rather, a bearer or carrier called as a vector is hereditary built to insert the desired gene.

Human population increased sharply during the Agricultural Revolution  because of improvements in farming techniques.

D)are descriptions of phenomena that can be observed to consistently happen over and over again

Explanation:

Scientific theory is the set of knowledge that seeks to explain, with a high degree of accuracy, comprehensive phenomena of nature, that is, it is different from the meaning of the word "theory" used in everyday life, when we say that something "is just a theory ”in the sense that it is mere speculation. An example of scientific theory is the Theory of Evolution, which explains how species change over time.

These theories develop from the arguments that verified certain hypotheses, which the scientists evaluated according to the scientific method.

Explanation:

Answer:

This is because fluids have a polar nature, so they couldn´t cross the lipidic bilayer that constitutes the plasma membrane

Explanation:

Plasma membranes are contituted by lipid bilayers. These kind of compounds are hidrophobic (they reject water) and don´t permit the freely passage of hidriphilic molecules that can disolve in water, constituing fluids. Because of that cells developed transport mechanism like endocytosis.

Answer:

While the heads of the phospholipid structure attract water, the tails are hydrophobic. The model shows how the hydrophilic section folds around the fluid molecules to bring them into the cell so they don’t need to pass through the hydrophobic tails.

Answer:

Salinity in an estuary varies according to one's location in the estuary, the daily tides, and the volume of fresh water flowing into the estuary. In estuaries, salinity levels are generally highest near the mouth of a river where the ocean water enters, and lowest upstream where freshwater flows in.

Explanation:

Answer:

An estuary can be defined as partially enclosed coastal body of the brackish water in which one or more than one  rivers flows into it.

It basically forms a transition zone between the river and maritime environments which is known as ecotone.

The salinity of the estuary depends on the location of the estuary. Salinity level in the estuary declines during the spring season and when the snow melts and the rain increases.

The level of the salinity increases during the time of summer because the level of evaporation increases.

"The process that puts carbon dioxide back into the air, other than carbon respiration or the carbon cycle, is known as ""decomposition.""

Decomposition is the breakdown of organic matter by decomposers such as bacteria and fungi. As these organisms consume the dead plant and animal material, they respire, releasing carbon dioxide back into the atmosphere. This process is a critical component of the carbon cycle, as it returns nutrients, including carbon, to the soil and atmosphere, making them available for reuse by plants and other organisms.

 In the context of the carbon cycle, when plants and animals die, their bodies are broken down by decomposers. The carbon in their tissues, which was originally taken from the atmosphere through photosynthesis, is released back into the atmosphere as carbon dioxide during decomposition. This continuous cycling of carbon between the living and non-living components of the Earth is essential for maintaining the balance of carbon in our biosphere."

The word would be used if the cell were from an animal is prokaryote which is the term used for an animal cell.

The prokaryotic cell has been defined as a cell which has one that lacks a true nucleus and membrane-bound organelles. The prokaryotic cell is the foundation of organisms in the domains Bacteria and Archaea.

In other hand the eukaryotic cells have a separate organelle named nucleus (plural: nuclei) which is a double membranous structure meant for the storage of genetic material i.e. chromosomes (DNA). Prokaryotes on the other hand have an irregularly shaped structure named nucleoid instead of nucleus.

All the genetic material of the prokaryotes is within the nucleoid. Unlike nucleus, nucleoid does not have any nuclear membrane & it is spread in the cytosol freely. Eukaryotic cells have nuclei but prokaryotic cells do not have nuclei.

Answer:

Hypotonic solution

Explanation:

A hypotonic solution causes a cell to swell due to osmosis. This happens because water molecules move from the solution, where there's a lower solute concentration, into the cell, where there's a higher solute concentration. However, if the cell swells too much, it can burst, a condition called osmotic lysis.

A solution that causes a cell to swell due to osmosis is called a hypotonic solution. Osmosis is the passive movement of water molecules, across a semi-permeable membrane, from an area of lower solute concentration to an area of higher solute concentration. In the case of a cell in a hypotonic solution, the concentration of solutes is higher inside the cell than in the surrounding solution. As a result, water moves into the cell, causing it to swell.

This process is an essential part of biology and it's vital for many biological processes, from the transport of nutrients to the balancing of water levels in organisms. Care must be taken, though, as too much swelling can lead to a condition called osmotic lysis, where the cell can burst.

Answer:

A. If populations can interbreed, they are considered one species.

Explanation:

The organisms of a species have the ability to interbreed with one another leading to the formation of an offspring. For speciation to occur, the organism have to get diverged and isolated.

In speciation, a hereditary species parts into at least two relative species that are hereditarily not quite the same as each other and can never again interbreed.

In Allopatric speciation, the species gets geographically parted from their parent and evolves accordingly while in sympatric speciation, evolution of species occur when it stays in the same place as their parent.
