Answer:

See the answer below.

Explanation:

Antibiotic-producing bacteria are generally known to have a mechanism that enables them to be resistant to their own antibiotics. The mechanism that enables them to be resistant to their own antibiotic depends largely on the mode of action of the antibiotic substance.  

Some of the popular mechanisms used by bacteria to counter their own antibiotic substance include a mutation in the target gene, production of enzymes that inactivate the antibiotic compounds, or efflux of the compounds.

In the case of Streptomyces griseus, the inactivity of streptomycin has been linked with the production of a phosphatase inhibitor that prevents streptomycin from getting access to the target site. Hence, the organism is not harmed by its own antibiotic.

C. The angle of the sun's rays and the number of hours of daylight.

The length of daylight hours and the angle at which the sun's rays hit the Earth's surface both have a big impact on the seasons. The Earth's axis is tilted in relation to its orbital plane as it revolves around the sun.

Because of this tilt, various areas of the Earth's surface get sunlight at varying angles throughout the year. When one hemisphere is inclined towards the sun, more direct sunlight falls there, resulting in longer daylight hours and higher temperatures, giving rise to summer.

Explanation:

Answer:

The primary reason is that the pollen grains are being struck by water molecules that move in different directions. These strikes fluctuate and sometimes are uneven.

Explanation:

This vibration and spread out of molecules in water is called Brownian Motion. It is the result of the collision of small particles of water with big particles of pollen. As the particles of water move randomly hitting different sides of the pollen particle, at times, there will not be a coordinated movement, but as the movement of water particles is random, there will be moments when one side of the pollen particle will collide with more water particles, when this happens there is an unbalanced force that makes the pollen particle moves in a direction.

The mangrove forest which holds the most Carbon dioxide followed by forest shown by second image and at last the vegetation on farms holds and releases the least amount of Carbon dioxide.

Carbon is transferred through one storage reservoir to another through a range of mechanisms. Plants, for example, transfer carbon dioxide from the atmosphere into the biome via photosynthesis in the food chain. They use solar energy to chemically incorporate carbon dioxide, hydrogen, and oxygen from water to form sugar molecules. Animals that consume plants metabolize the sugar molecules to obtain energy. Respiration, excretion, and decomposition all return carbon to the atmosphere or soil, thus completing the cycle.

Erosion, for example, releases carbon into the atmosphere slowly, whereas volcanic activity releases it quickly. Another way to quickly release carbon into the atmosphere is to burn fossil fuels in automobiles or power plants.

The best prediction for the frequency of brown seeds that would result from the homozygous dominant and heterozygous cross is 0.

According to the question the dominant allele result in black seeds and recessive allele in brown seeds. Let us consider R as the dominant seed and r as the recessive seed.

The botanist crosses a homozygous dominant plant with a heterozygous plant. A plant that is homozygous will have only the dominant allele (RR) while the heterozygous will have its genes blend the two alleles (Rr). Crossing the two gives,

RR x Rr = 2RR, 2Rr

R is dominant over r, hence from the genotypes of the offspring, RR and Rr will appear to have black seeds. Thus the frequesncy of black seed is 100 and for brown seed is 0.

Answer:

Burning fossil fuels, releasing chemicals into the atmosphere, reducing the amount of forest cover, and the rapid expansion of farming, development, and industrial activities are releasing carbon dioxide into the atmosphere and changing the balance of the climate system.

What are the top 3 human activities that produce CO2?

Eighty-five percent of all human-produced carbon dioxide emissions come from the burning of fossil fuels like coal, natural gas and oil, including gasoline. The remainder results from the clearing of forests and other land use, as well as some industrial processes such as cement manufacturing.

What causes carbon dioxide to increase in the atmosphere?

Human Activity Is the Cause of Increased Greenhouse Gas Concentrations. Over the last century, burning of fossil fuels like coal and oil has increased the concentration of atmospheric carbon dioxide (CO2). This increase happens because the coal or oil burning process combines carbon with oxygen in the air to make CO2.

Fragmentation is a form of asexual reproduction and is seen in annelids, fungi, cyanobacteria, sponges, and flatworms.

In Fragmentation, an organism divides itself into a number of fragments. It occurs when an organism completely breaks down independently irrespective of the other parts. Each one of these fragments matures into fully grown adults that are clones of the original organism.

Asexual reproduction usually involves the participation of a single parent alone can produce new offspring. The newly produced individual is genetically identical to one another and its parent. Both multicellular and unicellular organisms divide by fragmentation which is asexual reproduction.

Fragmentation is the most common method of reproduction in lower invertebrates. It is seen in many organisms including filamentous cyanobacteria, algae, lichens, molds, many plants, and animals such as flatworms,  annelid worms, sponges, and sea stars.

The organisms that can reproduce by fragmentation are Option d Sponges and Sea anemones.

Fragmentation is a form of asexual reproduction in which an organism breaks into two or more fragments, and each fragment develops into a new individual. Both sponges and sea anemones are examples of organisms that exhibit this mode of reproduction.

Sponges are simple multicellular animals that lack true tissues and organs. They possess a porous body structure, and when a sponge is fragmented, each fragment has the potential to develop into a new sponge through regeneration. These fragments contain specialized cells called archaeocytes that can differentiate into various cell types required for the formation of a new sponge.

Sea anemones, on the other hand, are marine animals belonging to the phylum Cnidaria. They have a cylindrical body with tentacles surrounding their mouth. When a sea anemone is fragmented, each piece can regenerate into a complete individual. The process involves the differentiation of cells within the fragments, leading to the development of new tentacles, body parts, and eventually a mature sea anemone.

Both sponges and sea anemones have remarkable regenerative abilities, allowing them to reproduce through fragmentation. This form of asexual reproduction enables them to colonize new areas, expand their population, and adapt to changing environmental conditions. Therefore the correct option is D
