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.

The greenhouse effect is caused by ______.
a buildup of carbon dioxide in the atmosphere
the trapping of the sun's heat
pollution from burning fossil fuels
all of the above
Answer:
all of the above im pretty sure
Explanation:
The greenhouse effect is caused by a buildup of carbon dioxide in the atmosphere, the trapping of the sun's heat and pollution from burning fossil fuels.
What do you mean by green house effect?The greenhouse effect is a process that occurs when energy from a planet's host star goes through the planet's atmosphere and heats the planet's surface, but greenhouse gases in the atmosphere prevent some of the heat from returning directly to space.
The greenhouse effect is the way in which heat is trapped close to Earth's surface by “greenhouse gases.” These heat-trapping gases can be thought of as a blanket wrapped around Earth, keeping the planet toastier than it would be without them.
One example of the greenhouse effect that most of us experience in everyday life is the warming of a car's interior when the vehicle is left out in the sun.

Explanation:
The correct word would be pollution.
Pollution can be described as the presence of ecologically harmful substances in the environment.
Littering the ground is considered pollution because it is harmful to the environment in the long term. Harmful chemical in water is outrightly considered pollution because this will hurt the organisms living in the water and rendered the water unusable to those around it.

Which of the following describes how both of these cellular division processes maintain genetic continuity?
А.Both processes involve the replication and division of identical genetic material.
B. Both processes creates cells with half the genetic material of the parent cells.
C. Both process involve the recombination and division of new genetic material.
D. Both processes create cells with twice the genetic material of the parent cells.
Answer: Both processes involve the replication and division of identical genetic material
Explanation:
During S phase interphase DNA is replicated and it is replicated as an exact copy
When a single cell divides into two cells through mitosis, genetic continuity occurs. One cell divides into two during the process of mitosis, and each of the two progeny cells has the same amount of DNA as the parent cell.
What is genetic continuity?The fact that when a cell divides, the resulting two daughter cells have the same number and type of genes as the original cell is referred to as genetic continuity. It also describes how when two sexually reproducing organisms mate, their offspring have the same number of genes as the parents. Nuclear division results in daughter cells with identical sets of chromosomes. Mitosis ensures the genetic continuity of the ancestral cells in the body's daughter cells. It consists of one fully equational division followed by a DNA synthetic phase. Because it creates a perfect copy of DNA for new cells, DNA replication helps to maintain species genetic continuity.To learn more about Genetic continuity refer to:

Jonathan designed an experiment to plant lima bean seeds. His variable was to change what kind of light each plant received. He
used a different kind of light with each plant. He hypothesized that the plant grown under the plant light would have the greatest
amount of growth. Did the data support the hypothesis? Explain.
Answer:
Yes, it was.
Explanation:
The data did support the hypothesis because the data given was generalized on the change of light each plant received. The hypothesis was that the plant light would have the greatest amount of growth. The data was the different light types and the hypothesis was which one he inferred would work best.
Answer:
- The type of plants used in the study

TRUE FALSE: Organisms can CHOOSE to have a mutation
Answer:
False
Explanation:
Organisms themselves cannot choose to have a mutation. However, it can be artificially done in labs.
Organisms can choose to have a mutation, but this is a false statement because mutation is not voluntary but involuntary and can be caused by many factors, such as environmental factors.
What is the significance of the mutation and its consequences?mutation has many consequences, such as the Mutations can cause developmental disorders such as birth defects, mutations can increase an individual's risk of developing genetic disorders, and they also reduce the genetic diversity of a population. Mutation leads to the loss of function in an essential gene, resulting in a decrease in the organism's fitness in the ecosystem.
Hence, organisms can choose to have a mutation, but this is a false statement because mutation is not voluntary but involuntary and can be caused by many factors, such as environmental factors.

Identify the phase of mitosis for each plant cell diagram shown below.
Answer:
1. Metaphase
2. Prophase
3. Telophase
4, 5, 6, 8. Interphase
7. Anaphase
Explanation:
Mitosis is a cell division involving the formation of two genetically daughter cells. The process of mitosis involves stages including: interphase, prophase, metaphase, anaphase and telophase.
Interphase is the resting stage of the cell. It is th stage where the cell prepares for the division. Numbers 4, 5, 6, and 8 in the image are stages of interphase.
Prophase is the stage where the chromosomes become visible and arrange in pairs. Number 2 in the image depicts a plant cell in prophase stage.
Metaphase is the stage where the chromosomes align at the equator/middle of the cell. This alignment orients the chromosomes for separation. Image 1 depicts this metaphase stage.
Anaphase stage is the stage where the chromosomes separate into opposite poles of the cell. Image 7 depicts the anaphase stage of this plant cell.
In the Telophase stage, the cell plate forms to divide the plant cell into two. This is shown in image 3.
The cellular phases include Interphase (Figs. 4, 5, 6, 8), Prophase (Fig. 2), Metaphase (Fig. 1), Anaphase (Fig. 7) and Telophase (Fig. 3).
The cell cycle can be divided into two major phases: Interphase and mitotic M phase.The Interphase is classified into three subphases: Growth G1 phase, synthesis S phase and Growth G2 phase.The M phase can in turn be divided into Prophase, Metaphase, Anaphase and Telophase.In conclusion, the cellular phases include Interphase (Figs. 4, 5, 6, 8), Prophase (Fig. 2), Metaphase (Fig. 1), Anaphase (Fig. 7) and Telophase (Fig. 3).
