The correct answer is (b)The duckbilled platypus lives near water. The duckbilled platypus is well adapted for the semi- aquatic lifestyle. They live in water and make burrows to stay safe from predators.

They live near water to save themselves from the harmful predators. They have a streamline body that helps in swimming and a dense water proof fur to provide thermal insulation as there is fluctuation in temperature in deciduous forest.

The flat streamlined body, dorsally placed eyes and nostrils, and dense waterproof fur that keeps the platypus warm are all aquatic adaptations. Long guard hairs keep the soft underfur dry even after hours in the water.

The issue of lactose intolerance is frequent. It takes place when your body is deficient in lactase, an enzyme made in the small intestine.

To break down lactose, the naturally occurring sugar found in milk and other dairy products, lactase is required. Undigested lactose causes gas to accumulate in the intestines.

For those who are lactose intolerant, eating lactose-containing dairy products causes stomach cramps and diarrhea to begin.

The prevalence of lactose intolerance is higher among older persons, who are more prone to develop it during maturity. African Americans, Hispanic Americans, American Indians, and Asian Americans are among the ethnic and racial groups that are more negatively impacted than others.

Therefore, The issue of lactose intolerance is frequent. It takes place when your body is deficient in lactase, an enzyme made in the small intestine.

If the number of chromosomes within the cells did not change, but new daughter cells were still made, the resulting daughter cells would have the same number of chromosomes as the parent cell.

This is known as mitotic division, which is a process of cell division that produces two identical daughter cells with the same number of chromosomes as the parent cell.

If the process of mitotic division was disrupted, it could result in a range of problems. For example, if the chromosomes did not segregate properly during mitosis, the resulting daughter cells could have an abnormal number of chromosomes. This is known as aneuploidy, and it can lead to genetic disorders and other health problems.

Additionally, if the process of mitotic division was disrupted, it could result in the accumulation of damaged or abnormal cells in the body. This can increase the risk of developing cancer and other diseases. Therefore, proper mitotic division is crucial for maintaining the integrity of the genetic material and ensuring the health of the organism.

Both animal and plant cells will be affected.

The new compound that prevents ATP production in eukaryotic cells would likely affect the mitochondria, which are the cellular organelles responsible for producing ATP through oxidative phosphorylation. Therefore, animal and plant cells, which are eukaryotic and contain mitochondria, would be affected by the compound.

Bacterial cells, on the other hand, may not be affected because they do not contain mitochondria. However, bacteria produce ATP through other metabolic pathways, such as glycolysis, the tricarboxylic acid cycle, and oxidative phosphorylation in the cell membrane. Therefore, if the compound also affects these metabolic pathways, bacterial cells may also be affected.

So, the correct statement is: Animal and plant cells would be affected because they contain mitochondria, while bacterial cells may also be affected if the compound targets other metabolic pathways used by bacteria to produce ATP.

What is mutant plant ?

The look of a plant's traits, most notably its foliage, flowers, fruit, or stems, can change as a result of mutations in plants, a phenomenon that happens naturally. For instance, a flower might display two colors that are precisely half and half. Frequently, the mutant plants recover their normal state the following season.

What is unpigmented ?

Pigments are a group of chemical substances used to give other materials their color. They have a strong hue. These chromogens are also known as biological pigments or biochromes, which primarily refers to the actual pigments.

Vacuole help in the storage and disposal of various substances. They can store food or other nutrients required by a cell.

Lytic vacuoles  function as reservoirs for ions and metabolites like pigments, acids, and toxic substances.

Explanation:

The main reason that life on Earth is carbon-based is because of the unique properties of the carbon atom. Carbon atoms can form strong bonds with other atoms, including other carbon atoms, which allows for the formation of complex molecules like DNA and proteins. Additionally, carbon atoms are relatively small, which makes them ideal for forming the millions of intricate chemical bonds and reactions that are necessary for sustaining life.

The fossils in the sediment layers of Earth appear as upper layers having more complex organisms than the lower layers which means option D is the right answer.

As the living progressed on nature Earth, the complexity of the species also increased and this was mainly to sustain the living conditions which were continuously changing for each species. The life on Earth was started in the form of bacteria which adapted and converted into reptiles, fishes and amphibians and finally the most complex organism mammal (human beings) were born.

So considering the order of chronology, if the organisms died and got submerged, it would be less complex organisms first in the lower layers and as life progressed and complex organisms began to die, they would form the upper layers on the Earth. Hence, complex organisms are the newest ones and will be found on the upper layers of sediments.

1. Random mating: Individuals must mate randomly, with no preference for specific genotypes or phenotypes.

2. Large population: The population must be large enough so that chance events, such as genetic drift, do not significantly affect allele frequencies.

3. No mutations: The alleles in the population must not be changing due to mutations.

4. No migration: There can be no migration of individuals or alleles into or out of the population.

5. No selection: Natural selection cannot be acting on the traits controlled by the alleles in question.
