If energy is released, free energy must be what?
Answer:
If energy is released during a chemical reaction, then the change in free energy from the conversion of the reactants to the products, signified as ΔG (delta G) will be a negative number.
Explanation:
Hope it helped!
Answer:
If energy is released during a chemical reaction, then the resulting value from the above equation will be a negative number. In other words, reactions that release energy have a ∆G < 0. A negative ∆G also means that the products of the reaction have less free energy than the reactants because they gave off some free energy during the reaction.

Use the diagram to answer the question. Between which parts of the molecule must the bonds be broken to form an ADP molecule?
The parts of the molecule whose bond must be broken to form an ADP molecule would be between C and D. Thus, option A would be correct.
The image is an illustration of the structure of ATP, Adenosine Triphosphate. The hydrolysis of the terminal phosphoanhydridic bond in ATP yields energy for metabolic reactions in biological systems and ADP (Adenosine Diphosphate) is formed as a result.
In this case, the terminal phosphoanhydridic is D. Thus, the bond between D and C must be broken for ADP to result.

Traditionally most units of time are based upon a)the motions of earth, b)the longitude of an observer, c)the motions of the moon, or d)the real motions of the sun
Answer:
The correct answer is option A (the motions of Earth).
Explanation:
The word "Time" may have different meanings, "Time" in a simple term, it is used to measure events, and it is the bedrock that is used to determine seasons. Time is measured in seconds, minutes, hours, days, weeks, months, years. Unlike clocks, and other different devices used to measure time, these devices were not available some centuries ago. So, time was measured in those centuries with the help of the knowledge of the rising and setting of the sun which are caused by the rotation of the Earth. The most standard unit of time used this day are all products of research Astronomers were able to do through studying the motions of the Earth. For instance, when the Earth makes a full rotation around its own axis, that signifies a day, which is a period of about 24hours. considering we have leap years, so it is not complete 24 hours.

In your own words describe how genetic diversity is increased through the processes of crossing over, independent assortment, and random sexual reproduction.
Answer: Genetic variation describes naturally occurring genetic differences among individuals of the same species. Gene duplication, mutation, or other processes can produce new genes and alleles and increase genetic variation. New genetic variation can be created within generations in a population, so a population with rapid reproduction rates will probably have high genetic variation. And there are the reasons.

What are the types of transport methods?
All higher organisms, including humans, animals, and plants, go through a process called transportation that is necessary, natural, and part of their physiological makeup. To support life, this interaction is significant as it capabilities by continually shipping, different fundamental materials to and from all pieces of the body including cells, tissues, and organs.Water, hormones, gases, mineral nutrition, organic material, and other things are the primary essential materials. An organism's various modes of transportation include:Active transport Passive transport Facilitated transportDiffusion.The term "active transport" refers to a process in which molecules use external energy to move from a lower concentration area to a higher concentration area against a gradient or obstacle.Any substance's overall movement from a higher concentration area to a lower concentration area is known as diffusion. This can occur between cells or within them. Due to the random movement of their particles, only gases and liquids experience diffusion. It is an essential biological process. It is how things enter and exit cells. It occurs naturally and does not call for any energy.The container or the particles themselves come into contact with one another. In the end, the particles cover the entire container. There is no stirring, shaking, or wafting during diffusion.We refer to this as the concentration gradient down because diffusion is the movement of particles from a higher concentration to a lower concentration.

Don came up with the hypotheses that butterflies prefer to eat nectar from white flowers Don conduct an experiment and learn that his hypotheses with not correct what should Don do next
Answer:
B
Explanation:
A. Don should change the data he collected to make it look like the hypothesis was correct.
B. Don should test a new hypothesis.
C. Don should communicate the results of his experiment.
D. Don should hide his results so that nobody can see that he was wrong.
The correct thing for Don to do would be to test another hypothesis.
Hypotheses are generalized statements without any experimental tests. Once they are tested and are found not to be true, the next thing is to discard them.
A hypothesis that has been proven not to be true no longer serves any purpose. The next thing would be for Don to make and test a new one.
The correct option is B.

When a person eats the yogurt, the 14 grams of protein will be A combined into monosaccharides. B combined into polysaccharides. C broken down into amino acids. D broken down into nucleic acids.
Answer:
C broken down into amino acids.
Explanation:
Proteins are one of the four major biological molecules. They are organic polymers made up of monomers called AMINO ACIDS. Proteins are contained in food we ingest and are subsequently digested or broken down into their amino acid components.
In this case, when a person eats yogurt (containing proteins), the 14 grams of protein will be broken down into amino acids during digestion by enzymes called PROTEASES. Note that every polymer will be broken down into its monomeric constituents during digestion.

4. Which of the following statements best describes how proteins and enzymes move within a cell?
The movement of proteins and enzymes within a cell is facilitated by intracellular receptors.
The movement of proteins and enzymes within a cell is facilitated by special organelles called transport receptors.
The movement of proteins and enzymes within a cell is facilitated by special organelles called magneto receptors.
The movement of proteins and enzymes within a cell is facilitated by membrane receptors.
Answer:
The movement of proteins and enzymes within a cell is facilitated by intracellular receptors.
Explanation:
Proteins and enzymes (which also are proteins) move inside the cell through intracellular receptors. These receptors are proteins capable of binding other molecules such as proteins and hormones in order to transport them to different cellular locations. Thus, intracellular receptors are key players in signaling pathways that trigger signaling events to regulate a particular function, for example, activating gene expression by transporting proteins to the nucleus.

In the Calvin cycle the conversion of energy poor carbon dioxide into energy rich glucose
A) atp is used
B) pyruvic acid is produced
C) oxygen is produced
D) nadph is made
Answer:
D)NADPH is made
A)ATP is used
Explanation:
Sorry to ask the two questions, I asked why the two options are in the process:Reduction. In the second stage, ATP and NADPH are used to convert the 3-PGA molecules into three-carbon sugar molecules, glyceraldehyde-3-phosphate ( G3P ). At this stage, it gets its name because NADPH donates, or reduces , electrons to a three-carbon intermediate to form G3P.[Ocultar detalhes]
The reduction stage of the Calvin cycle, which needs ATP and NADPH, converts 3-PGA (produced in the fixation stage) into a three-carbon sugar. This process takes place in two main stages:
Simplified diagram of the reduction step of the Calvin cycle showing the carbon atoms, but not the complete molecular structures. A 3-PGA molecule first receives a second phosphate group from ATP (generating ADP). Then, the doubly phosphorylated molecule receives electrons from NADPH and is reduced to form glyceraldehyde-3-phosphate. This reaction generates NADP + and also releases an inorganic phosphate.

Then, the doubly phosphorylated molecule receives electrons from NADPH and is reduced to form glyceraldehyde-3-phosphate. This reaction generates NADP + and also releases an inorganic phosphate.
First, each 3-PGA molecule receives a phosphate group from ATP, becoming a doubly phosphorylated molecule called 1,3-bisphosphoglyceride (and leaving an ADP as a by-product).
Second, 1,3-bisphosphoglycerate molecules are reduced (gain electrons). Each molecule receives two electrons from NADPH and loses one of its phosphate groups, becoming a three-carbon sugar called glyceraldehyde-3-phosphate (G3P) . This step produces NADP^+

The ATP and NADPH used in these steps are products of the photo-dependent reactions (first stage of photosynthesis). That is, the chemical energy of ATP and the reducing potential of NADPH, both produced with the use of light energy, keep the Calvin cycle running. Conversely, the Calvin cycle regenerates ADP and NADP^+

The fact that the children can have the same hair color but different eye color is explained by the Group of answer choices principle of dominance. law of independent assortment. law of segregation. principle of probability.
The fact that the children can have the same hair color but different eye colors can be explained by the LAW of independent assortment.
The law of independent assortment states that non-linked genes and chromosomes segregate (separate) in an independent manner during Meiosis. The independent assortment of chromosomes generates genetic variation by increasing the possible combinations of genes in offspring.The law of independent assortment was first observed by Gregor Mendel in 1865 during his experiment using pea plants.In conclusion, the fact that the children can have the same hair color but different eye colors can be explained by the LAW of independent assortment.
