In terms of biomes, a biotic factor is a living component, such as organisms, whereas an abiotic factor is nonliving, like temperature or soil. The biotic factor in the given options is the disease-causing microbe, as it directly influences the biotic community in an ecosystem.
Understanding Biotic and Abiotic Factors in a Biome
In the context of biomes and ecosystems, a biotic factor refers to the living components present in an environment. These living aspects, like animals, plants, fungi, and microorganisms, are vital for the maintenance and reproduction of ecosystems. On the other hand, an abiotic factor includes the nonliving elements such as soil, sunlight, temperature, and water, which can influence the living aspects of the ecosystem significantly.
An example of the interaction between abiotic and biotic factors is the reliance of plants on soil quality (abiotic) for nutrient uptake, which in turn affects the types and numbers of plant-eating insects (biotic) that can thrive in that area. These insects support higher trophic levels, such as birds and mammals that feed on them. An equilibrium between these factors is crucial for the health and longevity of the biome.
The answer to the review question 'Which of the following is a biotic factor?' is B. disease-causing microbe, as it is a living entity that can affect the health and behavior of organisms within an ecosystem.

How would a change to the sequence of nucleotides in a DNA segment affects the mRNA from DNA
A change to the DNA nucleotide sequence alters the mRNA and the resulting protein. Point mutations can be synonymous, mis-sense, or non-sense, affecting protein function by altering amino acid sequences or introducing a stop codon. Mutations in germ cells can lead to hereditary changes.
A change to the sequence of nucleotides in a DNA segment affects the mRNA and consequently the protein produced. There are three types of point mutations, including: synonymous mutations which do not alter the amino acid sequence, mis-sense mutations which result in a different amino acid, and non-sense mutations which introduce a premature stop codon. These mutations can change the effects of codon bias, potentially leading to issues in translation efficiency or even ribosome stalling if the corresponding tRNA concentrations are low.
The transcribed mRNA sequence from the given DNA 5'-ATGGCCGGTTATTAAGCA-3' would be 5'-AUGGCCGGUUAUUAAGCA-3'. A single nucleotide change might not change the protein if it's synonymous, but other types of mutations can alter the function by affecting the structure of the polypeptide, the enzyme's active site, or potentially creating a truncated protein due to a stop codon.
When a mutation occurs in a germ cell, it can lead to hereditary alterations in progeny. This demonstrates the importance of DNA integrity, as it determines the correct amino acid sequence in proteins, which is vital for cellular function. Changes in the DNA sequence can impact amino acid sequence and ultimately influence the structure and function of proteins synthesized by the cell.
Jake designed an experiment to demonstrate interactions between Earth systems. He tied a clear plastic bag firmly around some leaves of a plant as shown below. plastic bag tied on leaves of plant After two days Jake observed some water droplets inside the plastic bag. What does Jake's experiment best demonstrate? interactions between biosphere and atmosphere interactions between hydrosphere and geosphere interactions between geosphere and biosphere interactions between atmosphere and geosphere
Answer: option (1)
Explanation: This experiment clearly represents the interaction between the atmosphere and the biosphere.
Biosphere refers to the overall life forms on earth and their relationship with other elements that are present in the lithosphere, hydrosphere of geosphere.
Here the leaves where Jake tied plastic bags re considered to be part of biosphere, which he keeps it to react with the atmosphere.
Thus the correct answer is option (1).
Which of these is an example of an ectoparasitic relationship?
A parasitic association is one in which a species, the parasite, thrives off of another species, that is, the host, affecting it, and at certain occasion resulting in death. The parasite lives on or within the body of the host.
An ectoparasite refers to the parasite, which thrives on or in the skin, but not inside the body. For example, lice, ticks, and fleas are ectoparasites. Hence, the correct answer is option B.
A male mouse that is heterozygous for a mutant igf2 allele (igf2/igf2-) is crossed with a female who is homozygous for the wild-type igf2 allele. what would be the expected outcome of this cross?
A male mouse that is heterozygous for a mutant igf2 allele (igf2/igf2-) is crossed with a female who is homozygous for the wild-type igf2 allele. The expected outcome of this cross would be fifty percent of homozygous wild type and fifty percent of heterozygous mutant species.
Further Explanation:
The allele that codes the particular phenotype which is most common in a population is called the wild type allele. Mutant allele is referred as different type of allele from wild type. Wild type is dominant in nature. A recessive trait is defined as a trait that gets expressed by an individual when they show a homozygous recessive condition. This means that if an individual showing a recessive trait will definitely possess both the recessive alleles for that trait as recessive trait gets concealed by the presence of allele for dominant trait.
If the wild/normal gene is igf2 and the mutated gene is igf2-, then the genotype of the parent would be:
Male: igf2 / igf2, possible gametes: igf2 and igf2- Female: igf2 / igf2, possible gamete: igf2Then the resultant cross gives fifty percent of heterozygous for a mutant (igf2/igf2-) and fifty percent of homozygous for the wild-type (igf2/igf2).

In which organelle does photosynthesis take place? stoma vascular bundle mitochondrion chloroplast
Answer: The correct answer is- Chloroplast.
Photosynthesis is a process of formation of food (that is a carbohydrate) in green plants and algae by using CO2 (carbon dioxide) and water in the presence of sunlight.
This process takes place in a specialized membrane bound organelle that is termed as chloroplast.
This organelle contains a green pigment, chlorophyll, which absorbs the energy from sunlight and convert it into chemical energy in the form of ATP and NADPH.
The chemical energy is then utilized in the formation of carbohydrate (glucose) in the next phase, which is a light independent phase.
Thus, chloroplast is the right answer.

Are the fat bodies larger in male or female frogs why is this so
The fat bodies are generally larger in female frogs compared to males. This size difference is attributed to the roles these fat bodies play in reproduction.
In female frogs, the fat bodies serve as an energy reserve that is crucial for the production of yolky oocytes, which are essential for successful reproduction. These fat bodies store energy in the form of lipids and provide the necessary nutrients for the developing embryos.
During the reproductive cycle, female frogs undergo vitellogenesis, the process of yolk formation in the oocytes, which requires a significant amount of energy. The fat bodies mobilize lipids to support this energy-intensive process. Males, on the other hand, do not have the same reproductive demands and therefore typically have smaller fat bodies. Their reproductive role primarily involves producing sperm, which does not require the same level of energy storage as egg production.
Additionally, the size of the fat bodies can fluctuate seasonally and with the reproductive status of the frog. They tend to be largest during the breeding season when females are preparing to produce eggs. After oviposition (egg-laying), the fat bodies may shrink significantly as the stored energy is depleted.
In summary, the larger size of fat bodies in female frogs is a reflection of their greater energy demands for reproductive purposes, particularly in the production of eggs with substantial yolk reserves to support embryonic development.

N the species selection model, __________ is to macroevolution as __________ is to microevolution.
In the species selection model , Allopatric speciation is to macroevolution as sympatric speciation [ option d ] is to microevolution.
This is due to the fact that macroevolution involves large-scale changes that often result in the emergence of new species, such as allopatric speciation, in which populations are separated geographically.
Microevolution, on the other hand, involves a population's small genetic changes, often leading to different adaptations.
This could lead to sympatric speciation, in which new species form from the same ancestral species while living in the same area.
