detected by the spectrophotometer in our reaction?
A) Guaiacol
D) Tetraguaiacol
B) Peroxidase E) Hydrogen peroxide
C) buffer
Answer:
E) Hydrogen peroxide
Explanation:
Hydrogen peroxide is the substance that has a brown color and is detected by the spectrophotometer in our reaction.
Final answer:
A) Guaiacol is the substance that turns brown in the reaction involving hydrogen peroxide (H₂O₂) and is detected by the spectrophotometer. It serves as a reducing agent in the enzymatic breakdown of hydrogen peroxide by turnip extract peroxidase.
Explanation:
The substance that turns brown when detected by the spectrophotometer in the reaction involving hydrogen peroxide (H₂O₂) is guaiacol. In the process where turnip extract is used as a source of peroxidase, guaiacol serves as a reducing agent. When oxidized by the enzyme catalyzed reaction which breaks down hydrogen peroxide into water and oxygen, guaiacol transforms into a brown color. This brown coloration is a direct result of the enzymatic activity and is measured using a spectrophotometer for quantitative analysis.

Macro evolution is the theory that animals evolved over time into new species while micro evolution is more minute changes within a species, like a genetic mutation to help the species adapt to their environment. An example would be of a genetic mutation in the fur color of bears to make different types of bears like black bears, brown bears, polar bears, etc
Answer:
genetic changes among and within populations
Explanation:
Label the steps for protein synthesis in order, beginning with the first step
The steps for protein synthesis in order are:
1. Copy of one side of DNA strand is made (called mRNA, messenger RNA)
2. mRNA moves to cytoplasm, then ribosome.
3. mRNA goes through ribosome 3 bases at a time.
4. transfer RNA (tRNA) matches up with the open DNA bases.
5. tRNA releases the amino acid at the top, which joins the chain of amino acids being produced.
Answer:
Steps of protein synthesis:
1) DNA double helix unwinds into a single strand and exposes a sequence of nitrogenous bases, this is also known as the unzipping process.
2) Transcription: In this process, DNA transfer the genetic instruction to mRNA in the nucleus.
3) Translation: In this process mRNA couples the ribosomes & tRNA helps to bring amino acids to ribosomes. This process is known as Initiation.
4) Elongation: Anti-codons present on tRNA recognizes codons present on mRNA.
5) Termination: In this step when the stop signal on mRNA is reached, the process of protein synthesis is terminated.

What evidence did Darwin use to support his theory of evolution? Check all that apply.
in-depth studies of individual organisms
observations of fossils
finches on different islands had different types of beaks
young finches that acquired desirable traits as they aged
observations of different species with varying traits
Darwin used observations of fossils, variances in finches' beaks across different islands, and the diversity of traits among different species to validate his theory of evolution. These evidences solidified the basis for his concepts of natural selection and adaptive evolution.
Explanation:Charles Darwin used various forms of evidence to support his theory of evolution. This evidence played a critical role in the establishment of evolutionary biology as a valid scientific discipline. Key sources of evidence included observations of fossils, the noticeable difference in finches' beaks on different islands, and his vast observations of different species with varying traits.
His fossil observations allowed Darwin to perceive evolutionary change over long periods of time. The finches displayed how species could adapt in response to environmental factors, such as food availability, which impacted the form and function of their beaks. Moreover, his observations of diverse species exhibited the capacity of life forms to develop different characteristics in response to their circumstances, further grounding his argument for natural selection and adaptive evolution.

Molds, casts, coprolites, and petrified wood are all example of
Answer:
Molds, casts, coprolites, and petrified wood are all examples of fossils.
Explanation:
Molds are fossils formed by the authigenic preservation of an organism- it is covered gradually in mud or silt which hardens into rock leaving indents there after it has decayed. Similarly, casts are mineral deposit filled casts, which produce fossilized copies of the organism. Coprolites, fossilized fecal matter, are a type of trace fossil, which provides records the presence, diet and other habits of the organism in an area by its preserved excrement. Petrified wood,like molds and casts are mineralized, however the differs from molds as it has not undergone decay.
The correct answer is fossils.
Molds, casts, coprolites, and petrified wood are all examples of fossils. Fossils are the preserved remains or traces of animals, plants, and other organisms from the remote past. Here's how each of the given examples fits into the category of fossils:
- Molds are fossils that form when an organism's body decays completely, leaving a hollow space in the rock that is the exact size and shape of the organism.
- Casts are fossils that occur when the hollow space left by a mold is filled with minerals, creating a replica of the organism's body.
- Coprolites are fossilized feces that provide information about the diet and behavior of ancient organisms.
- Petrified wood is formed when the organic remains of a tree are replaced by minerals, turning the wood into stone. This process preserves the original structure of the wood in fine detail.
Each of these fossil types provides valuable information about the biology and ecology of past life on Earth.

The sun rotates
O
A. around Earth once per year.
O
B. at different speeds along its sphere.
O
C. every 31 days.
O
D. once per year.
Answer: B
Explanation: the sun is made of gas, which doesn't all spin together at the same speed like a solid rock would.
The sun rotates at different speeds along its sphere, a phenomenon known as differential rotation. The rotation period near the sun's equator is about 25 days and increases with latitude.
The correct answer to the question of how the sun rotates is B. at different speeds along its sphere. This phenomenon is known as differential rotation. Unlike a solid body like Earth, the Sun, being a gaseous body, does not rotate at a uniform speed. At its equator, the Sun's rotation period is about 25 days, but this rotation period increases with latitude — being around 28 days at latitude 40°, and up to 36 days near the poles. Galileo discovered this by observing sunspots and their movement across the Sun's disk, indicating that the Sun does indeed rotate on its axis.

O
O
O
A. They are both performed by animals.
B. They are both performed by plants.
c. They both produce glucose molecules.
D. They both require energy from the sun.
O
Answer:
B
Explanation:
Photosynthesis requires sunlight and produces glucose but animals do not carry out photosynthesis and animal cells do not have the chloroplasts to absorb sunlight. Therefore A is false as is C and D as respiration uses glucose and does not produce it. And respiration transfers energy to cells that needs it therefore sunlight energy is not required.
Hope this helps.
Photosynthesis and cellular respiration are interrelated processes where photosynthesis creates glucose and oxygen, which are then used in cellular respiration to produce energy, carbon dioxide, and water. They function as opposite halves of a cycle that facilitates the energy flow within ecosystems and helps regulate the levels of carbon dioxide and oxygen in the atmosphere.
Explanation:Photosynthesis and cellular respiration are related in that they are essentially opposite processes that work together to facilitate the flow of energy through living organisms. Photosynthesis is a process used by plants, algae, and certain bacteria to convert light energy from the sun into chemical energy stored in glucose, releasing oxygen as a byproduct. Cellular respiration is a process that all living organisms perform, in which oxygen and glucose, produced by photosynthesis, are used to generate ATP, the energy currency of the cell, with carbon dioxide and water being released as byproducts.
To sum up, while photosynthesis converts carbon dioxide and water into glucose and oxygen using the sun's energy, cellular respiration converts glucose and oxygen back into carbon dioxide and water while releasing usable energy stored in ATP. This cyclical relationship is critical for the energy flow and the constant recycling of carbon dioxide and oxygen in the Earth's atmosphere. It forms part of the larger carbon and energy cycle of our planet.
