A new species of bacteria is discovered that lives deep in the ocean sediments, where no oxygen is present. When scientists bring it to the surface and expose it to air, the bacteria cannot survive. Which phrase would best describe this organism?
Final answer:
The bacteria that cannot survive when brought to the surface and exposed to air can be described as strict anaerobes. They lack cellular defenses against oxidative stress and need anaerobic conditions to survive. In deep ocean sediments, where no oxygen is present, they can thrive.
Explanation:
The bacteria that cannot survive when brought to the surface and exposed to air can be described as strict anaerobes. These bacteria live in environments lacking oxygen and use anaerobic respiration or fermentation to survive. Oxygen can be lethal for them because they lack cellular defenses against oxidative stress. They are able to live deep in the ocean sediments where no oxygen is present, but cannot survive in the presence of oxygen.
Plants are green because they contain the protein chlorophyll. A bucket was left on the lawn for one week. When the bucket was removed, the grass under the bucket had
turned from green to a yellowish white color. This change is due to the interaction between the grass and
decomposer organisms in the soil, an abiotic factor
2
the amount of sunlight, an abiotic factor
increased moisture under the bucket, a biotic factor
the metal composition of the bucket, a biotic factor
Answer:
The amount of ⛅ sunlight .
Explanation:
PLEASE MARK AS BRAINLIEST
The grass turned from green to a yellowish white color due to decreased sunlight and possibly increased moisture under the bucket.
The change in color of the grass from green to a yellowish white under the bucket is most likely due to the decreased amount of sunlight reaching the grass.
chlorophyll, the green pigment in plants, is responsible for capturing sunlight for photosynthesis.
Without adequate sunlight, chlorophyll production decreases, causing the grass to lose its green color.
Increased moisture under the bucket may also contribute to the change in color, as excessive water can lead to stress and damage to the grass.

Provide a specific example of photosynthesis and cellular respiration working together.
Answer:
Photosynthesis makes the glucose that is used in cellular respiration to make ATP. The glucose is then turned back into carbon dioxide, which is used in photosynthesis. While water is broken down to form oxygen during photosynthesis, in cellular respiration oxygen is combined with hydrogen to form water
Final answer:
Photosynthesis and cellular respiration work together in the carbon cycle, where plants use carbon dioxide and water to produce glucose and oxygen through photosynthesis, and then the glucose is used in cellular respiration to produce ATP along with the release of carbon dioxide and water.
Explanation:
Photosynthesis and cellular respiration are two processes that work together to store and release energy in living organisms. An example of how they work together is through the carbon cycle. During photosynthesis, plants use carbon dioxide and water to produce glucose and oxygen. The glucose produced is then used in cellular respiration to produce ATP, and in the process, carbon dioxide and water are released as byproducts. This cycle ensures the continuous recycling of carbon and the availability of oxygen for organisms.
A hiker has become overwhelmed with heat while walking in the Grand Canyon. The hiker's body goes into overdrive to keep cool in the heat. The hiker needs to hydrate his or her cells. What process is used to regulate homeostasis?
A. Hydration B. Cellular transport C. Passive transport D. Balanced equilibrium
Answer:
A. Passive transport
Explanation:
Cell transport is the exchange of substances through the plasma membrane
The passive transport allows the molecular passage through the membrane in favor of the gradient of concentration or electrical charge, that is to say that it transports values of greater concentration at lower concentration, as it happens in the osmosis process where a transport of molecules of water mediated by specific proteins in favor of its concentration gradient.
Answer:
Cellular transport
Explanation:
The arrows in the chart above represent the movement of carbon between four reservoirs: the ocean, plants, fossil fuels, and the atmosphere. The numbers in the blue boxes show the gigatons of carbon moving each year. More carbon is moving into the vegetation for photosynthesis than is moving out to the atmosphere via respiration. This means that the vegetation reservoir is a carbon sink, taking in more carbon from the atmosphere than it is releasing to the atmosphere. A carbon source is the opposite. A reservoir that behaves as a carbon source releases more carbon to the atmosphere than it takes in.
Consider the statements listed here. Do they accurately describe potential changes in the model? Choose all that are correct.
Deforestation would result in a decrease in the carbon sink.
Increased use of alternative energy sources such as solar and wind energy would result in a decrease in released or sourced carbon.
If we consider non-industrialized countries, the model would remain the same.

Which molecule is most responsible for determining an organism eye color body structure and cellular enzymes production
DNA is the molecule that determines an organism's eye color, body structure, and cellular enzyme production. Traits of an organism are determined by specific parts of the DNA called genes. These genes command the construction of specific proteins that determine our physical attributes, produce enzymes for chemical reactions and influence our eye color.
Explanation:The molecule that is primarily responsible for determining an organism's eye color, body structure, and cellular enzyme production is DNA (Deoxyribonucleic Acid). DNA carries the genetic instructions for the development, functioning, and reproduction of living organisms. Its structure is a double helix and is composed of nucleotide base pairs.
The traits (for example, eye color) of an organism are determined by specific regions of DNA, called genes. Each gene provides the instructions required to construct a particular protein. These proteins have various roles within the body, including giving us our physical characteristics, producing enzymes that drive chemical reactions within cells, and determining our eye color.
For instance, in Drosophila, the gene for eye color is located on the X chromosome. Different versions of this gene (alleles) result in different eye colors. Similarly, proteins are responsible for forming the structure of our bodies and producing cellular enzymes that guide metabolic processes within the body.

A cross of a black chicken (BB) with a white chicken (WW) produces all speckled off spring (BW). This type of inheritance known as
Answer:
Codominance
Explanation:
When we say codominance, both traits of the parents are seen on the offspring. For example in your problem, the offspring is speckled meaning there is a mixture of both white and black, traits coming from each parent.
Do not confuse this with incomplete dominance. Incomplete dominance is similar but the difference is that the traits are "BLENDED". So let's say that if incomplete dominance occurred, the offspring would be gray.
The described inheritance pattern, in which a cross between a black and white chicken produces all speckled offspring, is known as codominance. This pattern of inheritance happens when neither of the two alleles of a gene is dominant or recessive, resulting in offspring that display traits from both parents.
Explanation:The type of inheritance described in the question, where a cross between a black chicken (BB) and a white chicken (WW) produces all speckled offspring (BW), is known as codominance. In codominance, both alleles are equally strong and both are expressed in the offspring's phenotype. In this case, neither the black color (B) nor the white color (W) is dominant over the other, resulting in a speckled combination of both colors (BW).
Bringing in a different context, in cases of codominance in mice, a cross between a black mice (A) and a white mice (a) will produce grey mice (Aa). Many genetic traits indeed follow this pattern of inheritance.

Which part of sunlight makes up the visible spectrum? Check all that apply. blue green indigo infrared ultraviolet
Answer: Blue, green and indigo.
Explanation: The visible spectrum of the electromagnetic radiation includes 7 colors and besides these 7 colors human eye cannot see other colors.
So the blue, green and indigo lies under the visible spectrum. A typical human eye can detect the wavelength from 380 to 740 nanometers.
Before this wavelength and after this wavelength human eye cannot see anything.
The visible spectrum of sunlight includes the colors blue, green, and indigo. Infrared and ultraviolet are part of the wider electromagnetic spectrum, but they are not visible to the human eye. Other species can perceive these ranges that are outside of the human range.
Explanation:The visible spectrum of sunlight includes the colors we can see, namely: blue, green, and indigo. It's important to understand that the visible spectrum is a portion of the larger electromagnetic spectrum. This visible spectrum, perceived by human eyes, is associated with wavelengths that range from 380 to 740 nm. However, the divisions between infrared, visible, and ultraviolet light, as well as those between the seven rainbow colors (red, orange, yellow, green, blue, indigo, violet), are not distinct. In the context of the question, the components of sunlight that make up the visible spectrum are blue, green, and indigo.
On the other hand, infrared light and ultraviolet light are part of the overall electromagnetic spectrum but are not visible to the human eye. Therefore, infrared and ultraviolet do not make up part of the visible spectrum of sunlight that we can see. Species such as honeybees and some snakes can perceive the ultraviolet and infrared ranges, respectively, which are outside of the human range.

Which process stops when ribsome reaches stop condon
Translation
Explanation: The method of translation practices energy to move the mRNA within the ribosome and to determine the peptide. The ribosome changes along the mRNA and the process repeats. The part of the polypeptide chain development and translation ends when the ribosome stops the stop codon on mRNA.
I apologize if this is not what you meant.
When a ribosome reaches a stop condon during translation, the process that ends is translation termination. This results in the completion of the polypeptide and the disestablishment of the translation complex.
Explanation:The process that stops when a ribosome reaches a stop codon is translation termination. When the ribosome encounters a stop codon (UAA, UAG, or UGA), the production of the protein, or polypeptide, is completed. Release factors trigger the detachment of the amino acid from its tRNA and the newly made protein is released. Subsequently, the small and large ribosomal subunits dissociate from the mRNA and from each other, freeing them up to participate in other translation initiation complexes.

A____ is a group of 3 nitrogen based on a mRNA molecule that carries the code for a specific amino arid. A____ is a set of 3 nitrogen bases on a tRNA molecule that matches a codon on an mRNA molecule
A codon is a group of 3 nitrogen bases on a mRNA molecule that carries the code for a specific amino arid. An anticodon is a set of 3 nitrogen bases on a tRNA molecule that matches a codon on a mRNA molecule.
A codon is a sequence of three nucleotides on mRNA that represents a specific amino acid, while an anticodon on tRNA matches this sequence. The genetic code is the set of rules dictating how codons are translated into proteins. Codons and anticodons play crucial roles in the protein synthesis process.
Explanation:A codon is a group of 3 nitrogen bases on an mRNA molecule that carries the code for a specific amino acid. Similarly, an anticodon is a set of 3 nitrogen bases on a tRNA molecule that matches a codon on an mRNA molecule. Each codon consists of three nucleotides, usually abbreviated with the letters A, U, G, and C. In the mRNA, uracil (U) is used whereas DNA contains thymine (T). The mRNA molecule instructs a ribosome to synthesize a protein according to the genetic code represented by these codons.
The genetic code is a set of rules by which information encoded in the genetic material (DNA or mRNA sequences) is translated into proteins by living cells. This information is carried by the sequence of codons in mRNA. For example, the codon AUG not only codes for the amino acid methionine but also serves as a start signal for translation. Moreover, there are 64 possible codons, more than the number of amino acids, which allows for some redundancy; several codons can specify the same amino acid. In addition, some codons function as stop signals to end protein synthesis.
