The direct visual examination of the tissues of the cervix and vagina using a binocular magnifier is known as

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.

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.

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.

In heterosporous plants microgametophytes produce sperm.

What are heterosporous plant ?

Heterosporous refers to the plants producing different types of spores that are different in structure, size and function.

What does heterosporous plant produce?

In heterosporous plants, there are two sizes of spores; the smaller (a microspore) produces a male gametophyte, and the larger (a megaspore) produces a female gametophyte.

Hence ,the correct option is B

Answer: The duodenum

Explanation:

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.

The answer is tropical areas. The tropical areas obtain more radiant energy from the Sun than they lose to space through terrestrial radiation, and vice versa for polar areas. Earth has an energy remaining in the tropics and an energy scarcity for the polar areas.

Answer:

tropical

Explanation:

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 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.

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

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).
