Answer:

The correct answer is - B. Lichens.

Explanation:

Lichens are one of the pioneer species that can grow on bare rock such as moraine and help make soil for further ecological succession and making ground for other species.

Breaking the bare rocks to convert into the soil is part of the primary succession. Lichens are colonized over these rocks and they contain acid which leads to the breakdown of the moraine and other rocks.

Answer:

A male's skeleton is usually thicker, rougher and appears more bumpy. ○ Due to the fact that males have larger muscles and therefore their skeletons require stronger attachment sites. Women who have borne children have scars on the surface of their pelvis. The femur (thigh bone) of a male is thicker than a females.

Answer:

Option D

Plants and animals living on one continent seemed more closely related to each other than to plants and animals living in similar regions on other continents.

Explanation:

From Darwin's discoveries, he noticed that there was a strong relationship between the environment and the characteristics of the living organisms present there.  He proposed that the environmental conditions affected the development of certain traits in organisms present there, in their quest for survival and adaptation.

These traits were passed down from parents to offspring, producing a population of organisms with similar character traits found around the same geographical location (continent in this case)

Answer:

Pili

Explanation:

The sex of bacteria is determined by a structure called Pilli. Pilli is not present in all species of bacteria, but within species that have this structure, such as Escherichia coli, pilli is considered an appendage present in male bacteria.

Pilli presents itself as a long hair and can also be called F factor or fertility factor and has a reproductive function, as it allows the conjunction between two bacteria (one with pili and the other without), where the male bacteria transmit genetic resources to within the body of the female bacteria , which will combine these resources with its own resources and will give rise to another bacteria.

Answer:

Most people believe that drinking milk can soothe heartburn.

Explanation:

Pseudoscience refers to practices and beliefs that are believed to be scientific but in actuality, do not follow any known scientific method. Even after it has been logically proven that these practices have no scientific backing people continue to believe in them because through confirmation bias, they believe that they work.

True science is evidence and research-based. Pseudoscience as seen in the last option is just based on belief.

Answer:

The nucleus contains nearly all of the cell's DNA, surrounded by a network of fibrous intermediate filaments and enveloped in a double membrane called the "nuclear envelope". The nuclear envelope separates the fluid inside the nucleus, called the nucleoplasm, from the rest of the cell.

Answer:

Look at the explanation

Explanation:

Nucleus is situated in the cytoplasm of the cell.

Usually, it is round but many different shaped nuclei can be seen in some cells.

It is surrounded by two porous membranes called nuclear membranes which remain continuous with the Endoplasmic Reticulum.

Within the nuclear membrane is present a liquid substance called nucleoplasm.

Nucleoplasm contains two types of chromatin material: Heterochromatin and Euchromatin.

Chromatin fibres are thin thread-like structures composed of DNA and proteins.

These fibres condense to form short thick chromosomes during cell division and become visible.

DNA molecules transfer hereditary information from one generation to the next.

As long as the ecosystem inputs remain the same, the ecosystem will remain stable. Only when there is a fire, drought, or other disturbance in the ecosystem, will the ecosystem change. A new set of plants will arise to most efficiently use the resources that are available under the new conditions. However, over time, if the disturbance is temporary, the ecosystem will eventually revert to the stable ecosystem that was there before the disturbance.

Stability (of an ecosystem) refers to the capability of a natural system to apply self—regulating mechanisms so as to return to a steady state after an outside disturbance.

Ecological succession is the process of change in the species structure of an ecological community over time.

Thus, it can be concluded that As long as the ecosystem inputs remain the same, the ecosystem will remain stable.

Explanation:

Answer: Protect yourself from the earthquake or volcanic eruption when it occurs because when this happens it is very likely that a tsunami will follow. Escape from the epicenter of the disaster, get as far away as possible from the water and get to a place as high as possible.

Explanation:

Indonesia is an archipelago of almost 20 thousand islands and it is located on the Pacific "Ring of Fire" which is a region where many volcanic eruptions and earthquakes occur independently of other events in other parts of the Ring. This means, Indonesia is vulnerable to volcano eruptions and earthquakes that eventually will cause tsunamis.

A tsunami is a complex event involving a group of waves in water of high energy and variable size that occurs when a large body of water is vertically displaced by some extraordinary phenomenon, for example, an earthquake, volcanic eruption, landslides, underwater detonations, meteorite impact, glacial ice slides, and others. So it is generated by the displacement of water.

The rist index for a tsunami to occur there is 9.7 of 10, this means that such an event is highly likely to occur. Since it is a natural phenomenon, there is no way to prevent it, however, there are several actions to take into account to avoid suffering major damage when this happens. This basically consists of protecting yourself from the earthquake or volcanic eruption when it occurs because when this happens it is very likely that a tsunami will follow. So you have to take it as a warning sign to flee in time. The most important thing is to escape from the epicenter of the disaster, logically get as far away as possible from the water and get to a place as high as possible, such as a mountain. It is necessary to be aware of the news and warnings to monitor the situation.

Answer:

Es probable que a través del tiempo la población de piojos también se vuelva resistente al segundo pijojicida. Los piojos resistentes se generan por un proceso de selección natural  

Explanation:

La evolución es el proceso mediante el cual los organismos cambian (evolucionan) con el tiempo con el fin de adaptarse a sus condiciones ambientales. La selección natural opera seleccionando aquellos individuos mejor adaptados al ambiente en el cual cada individuo se desarrolla. Los individuos adaptativamente superiores poseen más chances de sobrevivir y de reproducirse, trasmitiendo de este modo sus genes a la descendencia. Las mutaciones representan la fuente principal de variabilidad genética en la forma de nuevos alelos y genes. Las mutaciones que son beneficiosas y confieren una ventaja adaptativa son seleccionadas por selección natural. En este caso, la resistencia al primer piojicida se debió a la aparición de una o más mutaciones las cuales confirieron resistencia al primer compuesto. Con el tiempo, la frecuencia de los individuos portadores de mutaciones beneficiosas en la población de piojos fue incrementándose paulatinamente (como resultado del proceso de selección natural). Es muy probable que este proceso evolutivo también se repita con el segundo piojicida.

It is impossible to say. Fossils are very old; therefore, we cannot make observations of the turtle’s ancestors, and we cannot explain its body structures. Thus, option C is correct.

The turtle and hawk are different species, so they must not share an ancestor population. They inherited their atlas bone structure from separate ancestor populations. All species have their own specific body structures, so it is a coincidence that this turtle and hawk each happen to have the atlas bone structure.

The turtle and hawk both share the same ancestor population that had an atlas bone. They inherited this structure from the ancestor population. It is impossible to say. Fossils are very old; therefore, we cannot make observations of the turtle’s ancestors, and we cannot explain its body structures.

Therefore,  It is impossible to say. Fossils are very old; therefore, we cannot make observations of the turtle’s ancestors, and we cannot explain its body structures. Thus, option C is correct.

Answer:

- Alteration of an enzyme involved in folic acid synthesis

- A change in the structure of 23S rRNA

- The terminal D-alanine of pentapeptide mutates to D-serine

Explanation:

Antibiotic resistance is the phenomenon by which microorganisms naturally have, acquire, or develop the ability to defeat the drugs designed to eliminate them. For example, trimethoprim is able to bind with the enzyme dihydrofolate reductase (DHFR) in order to inhibit the folic acid synthesis pathway. Sulfonamides (sulfa drugs) competitively inhibit the incorporation of para-aminobenzoic acid (​PABA) into folic acid and thus also prevent the synthesis of folic acid. Ribosomes are organelles where proteins are synthesized. The 23S rRNA is a component of the large subunit (50S) of bacteria and archaea ribosomes. In consequence, it is expected that a modification in the structure of 23S rRNA alters protein synthesis. Finally, vancomycin acts by binding the terminal D-Ala-D-Ala residues of the polymeric lipid-PP-disaccharide-pentapeptides and thus inhibits cell wall synthesis in Gram-positive bacteria. In consequence, it is expected that a mutation at the terminal D-alanine that modifies this sequence alters the vancomycin binding site and thus also confers antibiotic resistance.

Your respiratory system prevents harmful substances from entering the lungs by using: .Mucus produced in the trachea and bronchial tubes to keep air passages moist and aid in intercepting dust, bacteria and other substances; The sweeping motion of cilia (small hairs in the trachea) to keep air passages clean

Mucus produced in the trachea and bronchial tubes to keep air passages moist and aid in intercepting dust, bacteria and other substances; The sweeping motion of cilia (small hairs in the trachea) to keep air passages clean.

Due to exchanges that occur in the alveoli, the amount of gases in the air that is breathed in and out varies. We only take in about 4 to 5 percent of the oxygen found in atmospheric air, and we exhale air with about 16% oxygen.

Normal air contains about 0.04% carbon dioxide, and as it diffuses from the blood into the alveoli, we exhale air with about 4% carbon dioxide. Exhaled air is hotter than that which we breathe in and includes more water vapor than that which we breathe in.

In contrast to ordinary smell, which occurs during the inhalation phase, the olfactory contribution to flavor occurs during the exhalation process. As a result, we can conclude that expired air differs from inspired air in terms of oxygen content, bacterial density, and water vapor content.

Therefore, Mucus produced in the trachea and bronchial tubes to keep air passages moist and aid in intercepting dust, bacteria and other substances; The sweeping motion of cilia (small hairs in the trachea) to keep air passages clean.
