The rate of color change will be faster in the light than in the dark. In normal lighting conditions, the slope is positive.
This suggests that the sample that was exposed to light produced less CO2 due to an increase in photosynthesis rate and an increase in pH. Under dark conditions, the slope is negative. Photosynthesis is the process by which light energy is transformed to chemical energy, resulting in the formation of organic molecules from carbon dioxide and water.
The process happens in practically all algae, and much of what we know about photosynthesis was uncovered through research on the green alga Chlorella.

the macromolecule that runs your body and expresses your traits
The macromolecule that runs your body and expresses your traits is Protein.
Carbohydrates, nucleic acids, and proteins are often found as long polymers in nature. Because of their polymeric nature and their large (sometimes huge!) size, they are classified as macromolecules, big (macro-) molecules made through the joining of smaller subunits.
The traits of a living thing depend on the complex mixture of interacting components inside it. Proteins do much of the chemical work inside cells, so they largely determine what those traits are.
For a gene to be expressed, a protein will bind to the promoter region, telling the cell to transcribe the DNA into RNA. The messenger RNA will go to a ribosome and provide the directions for translation, or making a protein. If for some reason a gene is not expressed, that trait won't show up.

____ is result of a mating where the offspring shows qualities superior to those of both parents
Cross breeding is result of a mating where the offspring shows qualities superior to those of both parents.
A intercross is an organism with thoroughbred parents of two different types, kinds, or populations. Crossbreeding, occasionally called" developer crossbreeding", is the process of breeding such an organism, While crossbreeding is used to maintain health and viability of organisms, reckless crossbreeding can also produce organisms of inferior quality or adulterate a thoroughbred gene pool to the point of extermination of a given strain of organism.
A domestic beast of unknown strain, where the strain status of only one parent or grandparent is known, may also be called a intercross though the term" mixed strain" is technically more accurate. Outcrossing is a type of crossbreeding used within a thoroughbred strain to increase the inheritable diversity within the strain, particularly when there's a need to avoid inbreeding.

Clastic sedimentary rock is the type of rock that is displayed. Conglomerates comprise clastic sedimentary rocks made primarily of rounded clasts the size of pebbles.
What sort of sedimentary rocks are clastic?Rock fragments (clasts) from older rocks make up clastic sedimentary rocks. Weathering causes rock fragments to become loose, which are subsequently moved to a basin or depression were sediment is trapped. Sediment becomes sedimentary rock when it is deeply buried, crushed, and cemented.

the swine flu virus can only infect pigs and humans. why can't it infect other species?
The swine flu virus is an influenza virus that is specific to the species of swine, which are animals such as pigs, hogs, and boars.
It is believed that the virus originally evolved from a combination of avian and human influenza viruses, and this is why it is able to infect both pigs and humans. However, the virus has not been found to be able to infect any other species. This is because the virus has only evolved to be able to attach to specific cell receptors that are found on the surface of pig and human cells. These cell receptors are part of the immune system and act as doorways to the cell, allowing the virus to enter and begin the infection process. Other species, such as cats and dogs, do not have the same cell receptors as humans and pigs, and therefore the virus is unable to enter their cells and cause an infection.

when atp is produced are blood glucose levels high or low
The blood Glucose levels lower down when the ATP is produced. As glucose is the predominant substrate in glycolysis, it serves as the principal source of energy for cellular activity.
Our blood plasma's primary source of free circulating sugar is this tiny, soluble molecule. In some cells, like those in the human brain, the first metabolic stage in cellular respiration is glycolysis, which is essential for cellular metabolism and the production of energy (ATP).These cells are particularly prone to damage from low glucose levels (hypoglycaemia), as they are unable to carry out respiration, which deprives them of energy and prevents them from carrying out their function. Low glucose levels have the potential to cause cell death or severe damage in brain cells, both of which are extremely harmful.

During the cellular respiration one molecule of Glucose is first broken down into two molecules of?
Cellular respiration is a metabolic process that converts the energy stored in carbohydrates, such as glucose, into a form that can be used by the cells of the body.
During this procedure, glucose is split into two pyruvate molecules.
After a series of subsequent events, the pyruvate molecules are further broken down, releasing energy in the form of ATP (adenosine triphosphate), which is subsequently utilised as an energy source by the cells.
Glycolysis, the first stage of cellular respiration, produces pyruvate as an intermediary. The conversion of glucose into two pyruvate molecules is known as glycolysis. There is no need for oxygen for this action, which takes place in the cytoplasm of the cell.
The pyruvate molecules created in this process are subsequently used in the subsequent oxygen-dependent phases of cellular respiration that take place in the mitochondria. The pyruvate molecules are further broken down during these processes, producing energy in the form of ATP.

A specific elastic object, such as a spring, can deform and store potential energy, which is known as the spring's potential energy. It describes the labour involved in stretching the spring and is dependent on both the spring constant (k) and the length of the stretch.
A sort of energy that can be stored but is reliant on the locations of various system components in relation to one another is known as potential energy. A spring gains potential energy when it is stretched or compressed. In comparison to being brought to Earth, a steel ball has higher potential energy when it is raised beyond the planet's surface.

What are the 5 steps of waste hierarchy?
The waste hierarchy is a system of prioritizing actions to manage waste in an environmentally responsible way. It consists of five steps Prevention, Minimization, Reuse, Recycling, and Disposal.
Prevention: The best way to manage waste is to prevent it from being generated in the first place. This can be done by reducing the amount of waste produced, designing products that are easier to recycle or reuse, and finding ways to use resources more efficiently.
Minimization: If waste cannot be prevented, the next best option is to minimize it. This can be done by reducing the amount of waste produced, reusing items instead of disposing of them, and recycling materials to create new products.
Reuse: Items that cannot be prevented or minimized should be reused as much as possible. This includes repairing and refurbishing items to extend their lifespan, as well as donating or selling items that are still in good condition.
Recycling: Recycling involves processing waste materials into new products, reducing the need for materials, and conserving resources.
Disposal: Disposal should be the last resort and is only appropriate for waste that cannot be prevented, minimized, reused, or recycled. Disposal methods should be carefully chosen to minimize environmental impacts, such as landfilling waste in a properly designed and managed facility.
