Saliva
Rabies virus is an infectious virus which causes rabies in human and animals. Rabies is transmitted mostly through the saliva of infected animals such as birds and bats. Transmission of the virus through the human saliva is rare. Signs and symptoms of rabies virus include fever, headache, partial paralysis, and vomiting.
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.
Complete question :
In the species selection model, __________ is to macroevolution as __________ is to microevolution.
A. exaptation; adaptation
B. genotype; phenotype
C. disruptive selection; balancing selection
D. allopatric speciation; sympatric speciation

Meiosis i produces ____ cells, and meiosis ii produces ________ cells
a. two diploid, two haploid
b. two diploid, 4 haploid
c. two haploid, 4 haploid
d. two haploid, two haploid
e. two somatic, two gametic
Meiosis i produces two diploid cells, and meiosis ii produces _4 haploid cells
When cells divide, they do so either by Mitosis or Meiosis.
Mitosis, discovered by Walther Flemming involves the asexual type of reproduction where the cells divides once producing 2 diploid daughter cells, which are genetically identical
while
Meiosis discovered by Oscar Hertwig involves the sexual type of reproduction where the cells divide two times to produce 4 haploid daughter cells that are genetically different.
Two stages of Meiosis occurs, The meiosis I like Mitosis, produces 2 diploid daughter cells and Meiosis II produces 4 haploid daughter cells.

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).

An interaction in which drugs combine in the body to produce extremely uncomfortable reactions is called antagonism. synergism. intolerance. cross-tolerance.
The right option is Intolerance
Drug Intolerance is a situation in which drugs cause adverse effects such as drowsiness or stomach upset and the body is unable to tolerate or bear these effects. An individual with drug intolerance may be able to continue with the drugs if the dose is reduced because drug intolerance sometimes disappears as drug therapy continues.
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.
