Hello. Your question is incomplete. The complete question asks for the correct answer to be found based on Catalase is an essential enzyme in living beings since all cells need it.
Answer:
B. Cells only function within a specific temperature range because enzymes only function within a specific temperature range.
Explanation:
Catalase needs to be present in all cells of the living organism because it is responsible for the decomposition of hydrogen peroxide that cannot stay inside cells for long periods of time. Following this type of reasoning, we can say that it is necessary to maintain a constant temperature for the enzymes of an organism to function well because all enzymes have a specific temperature range, even catalase.
The specific temperature range determines that the enzymes will only work within that range. Therefore, an environment where the temperature is below or above that specific range, can prevent the enzyme from functioning and even cause irreversible damage to the enzyme.

Which of the following mutations would most likely be passed along to an organism's
offspring?
A. Mutation that occur during crossing over during the prophase stage of mitosis
B. Mutations that occur in both DNA strands synthesize do the S-phase of mitotic cell cycle
C. Mutations that involve translocation of chromosomes in gametes
during meiosis
D. Mutations that occur in Somatic cells During cell division
Mutations that involve the translocation of chromosomes in gametes during meiosis are likely to be passed to offspring (Option C). It is because mutations are inherited from germinal cells.
Mutations and MeiosisMeiosis is a cell division by which a cell produces four daughter germinal cells having half of the genetic material.
Moreover, a mutation is any alteration in the genetic material of the genome of an organism.
Germinal mutations can be inherited because they occur in the germinal meiotic cells, whereas mitotic (somatic) cells are not inherited.

Why is it necessary to genetically engineer the bacteria to produce insulin instead of inserting the insulin gene in humans?
Answer:
????????????????
Explanation:
RDNA technology made it possible for bacteria to express an insulin gene from humans for production of insulin synthetically.
What is recombinant DNA technology?Alteration of genetic material from one organism to another, to obtain desired and enhanced genetic characteristics in recombinant organism, is called as recombinant DNA technology.
In this method different genetic material from different organisms can be combined to develop desired characteristics, for example, DNA from two different species is joined together, and the recombinant DNA molecule is then inserted into host organism to produce new genetic combination with higher medicinal, scientific or agricultural values.
Genetically modified bacteria are used for production of human insulin, which cause less immune reactions as compared to the pig or cow version of insulin.

Taken together, these facts demonstrate that it is critical that global societies and scientists
A) use more detailed common names to identify species,such as the "violet crow" or the "American crow."
B) use the genus and specific epithet scientific name to identify taxa.
C) use DNA sequences when referring to a particular species.
D) track diseases like West Nile virus using remote sensing technology on birds to help predict illness spread.
E) invoke higher levels of the classification system, such as kingdom and domain, when referring to a species.
Answer:
D) track diseases like West Nile virus using remote sensing technology on birds to help predict illness spread.
Explanation:
The West Nile virus affects many animals, among which there are many bird species. Birds turn to be one of the most important ones, not only because the virus keeps on nature through the cycle mosquito-bird-mosquito, but also because they act as dispersal organisms that carry the virus through long distances.
Due to its mortality and the many organisms it affects, it becomes a need to track the affected birds by the West Nile virus to make prevention through predictions about the distribution area and the periods in which it is more feasible for the virus to attack. It is particularly interesting to apply these tracking technologies to birds. They are severely affected by the West Nile virus and might carry and spread it faster in broad areas due to migration.
Getting to know
the environmental conditions under which the virus is more active,the recognition of the local mosquito species that are dangerous in each particular area, the migration routes of involved birds, and letting people know about all the prevention measurementsare the tools that provide higher chances to avoid the fast spread of the illness.

If a dog starts to put its paw down on a sharp stone, the tough skin skin protects underlying structures from damage. Additionally, touch receptors in the skin send sensory signals to the spinal cord. The spinal cord then sends a signal to the muscles to lift the paw rather than continuing to press down. In this scenario, the dog may experience discomfort but avoid injury.
What two body systems are being used to protect the structures beneath the dog's skin and signal the muscles to lift the paw?
A.
integumentary and nervous systems
B.
circulatory and nervous systems
C.
circulatory and lymphatic systems
D.

PLZZ HELP QUICKKK
The two body systems being used to protect the structures beneath the dog's skin and signal the muscles to lift the paw are the integumentary and nervous systems, which are in option A.
What is the organ system?The dog's response to the sharp stone involves the coordinated action of two body systems: the integumentary system and the nervous system. The integumentary system consists of the skin and its associated structures, including hair, nails, and glands. The skin acts as a protective barrier between the external environment and the underlying tissues, and it has specialized structures, such as tough, keratinized layers in the paw pads, that can withstand pressure and protect the sensitive tissues underneath.
Hence, the two body systems being used to protect the structures beneath the dog's skin and signal the muscles to lift the paw are the integumentary and nervous systems, which are in option A.

A. random mutations in each generation made mosquitoes resistant to DDT.
B. some individuals in the original population had the mutations that led to resistance.
C. DDT caused the mutations that led to resistance.
D. somatic mutations in the original population were passed on to subsequent generations.
E. by chance, new mutations that led to DDT resistance arose after DDT was used.
Answer:
B
Explanation:
A population of mosquitoes is exposed to the pesticide DDT for several generations. At the end of that time, most individuals in the population are resistant to DDT and the most likely reason is that some individuals in the original population had the mutations that led to resistance. Option B is correct.
What is mutation ?Mutation is the change in which there is slight change in the genome sequence of a DNA or RNA along with the gene. The mutation lead to various types to adaptations along with the diseases.
Resistance is the condition when the species on the multiple exposures develop certain kind of adaptations to it and these traits are sometime inherited sometimes not inherited.
Mutations are friendly as well where sometimes a disease causing mutation can be altered with the further mutation in it.
Therefore on the multiple exposure it led to condition of resistance in the species.

A) leech
B) bristle worm
C) water scorpion
D) dragonfly nymph
Answer
The correct answer is A) leech
Explanation:
According to the dichotomous key organism 3 is a leech. Therefore, option (A) is correct.
What is a dichotomous key?A dichotomous key is a tool used by biologists to identify organisms based on their characteristics. It consists of a series of questions with two possible answers for each question. By following the path of the key, the user can narrow down the possible identities of the organism until a final identification is reached.
Dichotomous keys are often used to identify species in fieldwork and can be based on physical characteristics such as color, size, and shape, or other traits such as behavior, habitat, and geographic range. These keys provide an efficient way to identify organisms and are widely used in fields such as ecology, botany, and zoology. However, the accuracy of a dichotomous key depends on the quality and specificity of the questions used and the expertise of the user in interpreting the results.
