Answer:

The Biosphere

Explanation:

The biosphere is a thin life-supporting portion on Earth's surface, extending  a few km into the atmosphere to the deep-sea. It is composed of living organisms and nonliving factors from which the organisms derive energy and nutrients.

The container or jar with snails crawling on the living plants would be the one where organisms be able to continuously cycle oxygen and carbon dioxide gases. Thus, the correct option is B.

Gas exchange is the physical process by which different gases move passively by diffusion across a surface. For example, this surface might be air or water interface of a water body, the surface of a gas bubble in a liquid, or a biological membrane which forms the boundary between an organism and its extracellular environment.

A sealed container is mainly comprised of a jar with snails which is crawling on the living plants, represents continuously cycle oxygen gas and carbon dioxide gases between the two organisms. The plants produce oxygen gas by consuming carbon dioxide in the photosynthesis process, and the snails produce carbon dioxide and consume oxygen gas during the respiration process.

Therefore, the correct option is B.

Meiosis is the common factor which is responsible for the production of new combinations or recombination in the organisms which reproduce through sexual mode of reproduction.

Meiosis is a special type of cell division which occurs in the germ cells in organisms which reproduce through sexual mode of reproduction. These organisms produce the gametes, such as sperms or egg cells. Meiosis involves two rounds of division which ultimately result into formation of four daughter cells with only one copy of each chromosome.

Recombination or new combination results when two molecules of DNA exchange pieces of their genetic material with each other. One of the most common examples of recombination can be observed during meiosis specifically, during the prophase I stage, when homologous chromosomes line up in pairs and swap some segments of their DNA.

Explanation:

Any trait that is to be considered as a competitive advantage, trait must allow the individual to survive better and reproduce more in that environment.

What is evolution?

Evolution is the change in the characteristics of a species over several generations and relies on the process of natural selection. It is decent with modification from preexisting species.

The trait that has the ability of relative fitness which means relative survival and relative reproduction shall be considered as more competitive. Both of these, criteria possess a competitive advantage.

Hooves are more advantageous for horses in the modern era because hooves are better suited for environments with a wider range of vegetation. Hooves help horses run farther and faster on the open prairies, helping them flee from predators and find fresh grass for grazing.

The species which is most likely to adapt and evolve to this change is an insect species with high reproduction rates and a significant mutation rate. This is because insect belongs to r-selected species that have fewer chances of extinction as compared to k-selection species.

The factor which is driven by random events is Genetic variations.

The factor which is most likely guarantee evolution rather than extinction is higher reproduction rates. Because a higher reproduction rate is a characteristic of r-selected species.

Answer for question 2:

It is important to receive data from three separate locations because the more we know  about the seismic waves and the places that they are more we gain for learning  about them.

Explanation:

It is important to receive data from three separate locations because the more we know  about the seismic waves and the places that they are more we gain for learning  about them.

Although it is frequently used interchangeably with "seismograph," a seismometer is the internal component of the seismograph, which can be a pendulum or a mass set on a spring.

Seismographs are tools used to capture ground motion during an earthquake. They operate as a part of a seismographic network and are buried throughout the world. The Chinese scholar Chang Heng created the first "seismoscope" in the year 132 A.D.

However, this just served to signal that an earthquake was taking place; it did not record earthquakes. In 1890, the first seismograph was created.

A seismograph is firmly fixed to the earth's surface so that, with the exception of the mass on the spring, the entire instrument shakes when the earth moves.

Therefore, It is important to receive data from three separate locations because the more we know  about the seismic waves and the places that they are more we gain for learning  about them.

Among biomolecules, nucleic acids, namely DNA and RNA, have the unique function of storing an organism's genetic code—the sequence of nucleotides that determines the amino acid sequence of proteins, which are of critical importance to life on Earth. ... Proteins themselves are major structural elements of cells.

Bio molecules are related to the cell cycle such that they partake in the

numerous activities such as cell division that occur in cell cycle.

Bio molecules such as DNA and RNA store the genetic traits of the

organism. These traits are usually passed to the offspring during cell division

in the cell cycle. DNA contains other bio molecules such as protein which

forms the base pairs.

Cell division such as meiosis gives rise to four unique daughter cells and

mitosis gives rise to two identical cells. The bio molecules basically assist in

the passing of traits to their offspring.

Photosynthesis stores energy because energy is released when glucose is formed from carbon dioxide and water. The passage describes a condition that is inherited.

Energy from the Sun flows into plants through photosynthesis, which is also known as “putting together with light,” and eventually into humankind. In the end, humans are powered by the Sun's energy to eat and survive. Thus, option D is correct.

Solar energy is converted into chemical energy during photosynthesis, which produces glucose from water and carbon dioxide. The by-product is the emission of oxygen. In the process of breaking down glucose during cellular respiration, oxygen is consumed, which also produces heat and chemical energy.

Photosynthesis is the tremendous energy flow that underlies electricity and is the foundation of all life. Whether we are vegetarians or not, we joyfully devour our food without giving the basic mechanism that provides us with this gift even the least thought.

Therefore, Because energy is released when glucose is created from carbon dioxide and water, photosynthesis saves energy. The paragraph mentions a hereditary ailment.

Remember, someone with an h.o.m.o.z.y.g.o.u.s gene basically inherits two identical alleles; one from their biological mother and the other their biological father.

In this scenario, the real concern should be to determine the probability that the girl child inherits a dominant allele that contains the gene that causes albinism. Hence, since there's little information about the gene type of the parents, a concise assumption can be made, thus rendering the listed options unlikely.

Between three and eight carbon atoms can be found in a monosaccharide, although only those with five (pentoses) and six (hexoses) are typically seen in nature.

The most prevalent monosaccharide is glucose, often known as dextrose or blood sugar. However, glucose accounts for a very minor portion of the total carbohydrates in a regular diet.

The majority of the time, glucose is only consumed when it is joined with other sugars to form a poly- or disaccharide.

The three monosaccharides that are most prevalent are glucose, fructose, and galactose. The monosaccharide category also comprises sugar alcohols and pentoses in addition to these three sugars.

Therefore, monosaccharides have a backbone of five or six carbon atoms.

Answer:

Osmosis is the passive transport of water molecules across a selectively permeable membrane. In osmosis, water moves from an area of high concentration (high water potential) to an area of low concentration (low water potential) in order to balance out the concentration on both sides of the membrane. This process can be observed in living cells, where the membrane surrounds the cell controls the flow of water and other molecules in and out of the cell.

In simple words, Osmosis is a type of diffusion that specifically refers to the movement of solvent molecules through a selectively permeable membrane. It is a fundamental concept in biology and is crucial for the proper functioning of cells and organisms.
