tropical

Explanation:

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.

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.

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.

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 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.

Prokaryotic DNA is found in the cytoplasm, specifically within a region called the 'nucleoid', and is typically in a circular form. Eukaryotic DNA is located in the nucleus of the cell and is linear, forming chromatin and chromosomes.

In a prokaryotic cell, the DNA is found in the cytoplasm, more specifically within a region called the 'nucleoid'. Unlike eukaryotic cells, prokaryotic cells lack a defined nucleus, so the DNA is not contained within a nuclear envelope. The DNA in prokaryotic cells is typically in a circular form.

On the other hand, in eukaryotic cells, the DNA is found in the nucleus of the cell, which is separated from the cytoplasm by a nuclear envelope. Unlike prokaryotic DNA, eukaryotic DNA is linear and associated with proteins to form a material called chromatin, which condenses to form chromosomes during cell division.

Homologous chromosomes carry information for the same traits but are not necessarily identical as they may have different alleles. They line up at the metaphase plate during metaphase I of meiosis, not meiosis II, and undergo recombination to produce genetic diversity. Thus, option D is correct.

Homologous chromosomes are pairs of chromosomes that have the same size, shape, and contain the same genes. However, they are not necessarily identical as they may carry different alleles of the same genes. The correct answer to the student's question is d. carry information for the same traits. During the first division of meiosis, specifically in metaphase I, homologous chromosomes line up at the metaphase plate, but they do not align on the metaphase plate in meiosis II; that is when sister chromatids line up. Homologous chromosomes do carry information for the same traits but can have different versions of the same gene, known as alleles. These chromosomes undergo a process called recombination, or crossover, during which they exchange segments of genetic material to produce genetic diversity.

Insects provide valuable information in forensic science by indicating the time since death, the presence of drugs or poisons, and whether a body has been moved after death. The study of insects on remains aids in solving crimes such as murders and poaching and contributes to a branch called environmental forensic entomotoxicology.

Insects play a pivotal role in forensic science, particularly forensic entomology, which is the study of insect biodiversity and its application in criminal investigations. Insects such as flies and beetles are the primary decomposers of carcasses, and their presence can reveal critical information regarding the time of death, whether the victim was exposed to drugs or poisons, and even if the remains were moved post-mortem. For example, forensic entomologists can examine the age of maggot larvae on a decomposing carcass to determine the minimum time that has passed since death. This is because certain species of flies, like blow flies, are known to arrive and lay eggs on a carcass very shortly after death occurs.

In the context of poaching and environmental crimes, the type of insects found on animal remains can indicate whether toxins were present in the animal's tissue, which may point to the use of poisons or pollutants. Moreover, if carcass remains contain insect species not native to the region where they were found, this could imply that the remains were moved. Such is the case with poached African animal parts that harbour Asian insects, suggesting a transcontinental journey. This aspect of forensic entomology, known as environmental forensic entomotoxicology, integrates the study of insect diversity with environmental conservation and toxicology.

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.

The basal ganglia, not part of the brainstem, are significantly involved in motor control and can lead to motor impairments if damaged.

The part of the brain that is not a part of the brainstem and is significantly involved in motor control is the basal ganglia. While the brainstem, consisting of the midbrain, medulla oblongata, and the pons, is crucial for motor control, as well as a wide array of other autonomic functions such as breathing and heart rate, the basal ganglia play a distinct role in movement control and posture. Damage to the basal ganglia can lead to motor impairments which are often seen in conditions such as Parkinson's disease.

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

The increase in light-colored moths is linked to the reduction in industrial pollution. As environmental changes occurred, lighter moths became better camouflaged and their populations increased—a phenomena known as industrial melanism and an example of directional selection.

The increase in light-colored moths can be attributed to a biological process called directional selection, linked to changes in industrial pollution levels. During the Industrial Revolution in England, dark-colored moths—specifically Peppered Moths (Biston betularia)—predominated due to the camouflaging effect of soot-covered landscapes, which offered them protection against predators. Factories discharged soot, which darkened the environment and provided a favorable background for the dark-colored moths, making them less visible to predators.

However, as factories began to incorporate scrubbers and air purifiers, which reduced pollution levels, the color of the environment gradually lightened. This shift, in turn, favored the light-colored moths, which became better camouflaged against the cleaner environment, hence their increase in number. This phenomenon, known as industrial melanism, showcases how environmental factors can direct natural selection.
