Plants are called as natures air purifiers because they perform photosynthesis in which they take in carbon dioxide from the atmosphere and give out oxygen .

❤️

plants are a natural type of filter and can purify the air of harmful contaminants. It’s no wonder why the air purifier vs indoor plants debate is such a hot topic. Unfortunately, plants can’t absorb all forms of air pollution.

Answer:

Evolution means change in the physical features of an organism.

Explanation:

Evolution means change in the physical features of an organism. Evolution occurs in the population of an organisms due to various factors such as mutation, non-random mating and natural selection. Nonrandom mating occurs when an organism prefer mating with particular superior organisms or with the similar organism. Mutation in the genetic makeup of an organism is also responsible evolution. this mutation occurs when an organism experience ultraviolet radiation from the sun, or also occur if an error in DNA during cell division. Gene flow is also known as gene migration is the transfer of genetic material or traits from one population to another when the organism is migrated to another environment. Some organisms are selected naturally because they have the potential to survive in that environment so they survive and that doesn't adopt itself to the environment, it will extinct from the environment.

Answer: Higher temperatures are bad for fish development, growth, feeding, and spawning, and causes coral bleaching. Polar ice is melting, causing the loss of habitat for Arctic animals, Antarctic krill decline, and algae diminishing, which is serious because it's the foundation of the Arctic food web. Rising sea levels will flood 10% of the world's population, because they live at or below sea level, small island nations in the Pacific ocean will be wiped off the map, coral reefs, mangroves, and sea grasses will be unable to keep up with the rising sea levels, and critical coastal habitats, such as sea turtle nesting beaches, will disappear. Warming the oceans alters sea currants and changes the chemistry of seawater. This changes marine species' migratory patterns, and many species that depend on the currant for nutrients or reproduction will be affected by it. Oceans with high carbonic acid harm shell-forming organisms, such as corals, scallops, lobsters, crabs, and some microscopic plankton that are a foundation of the food web across the ocean. Increased acidification limits the ability of certain fish to detect predators, disturbing the food chain.

Answer:

Biological diversity - or biodiversity - is the term given to the variety of life on Earth and the natural patterns it forms. The biodiversity is the fruit of billions of years of evolution, shaped by natural processes and, increasingly, by the influence of humans.

Explanation:

Biodiversity is important to humans for many reasons. ... Ecological life support— biodiversity provides functioning ecosystems that supply oxygen, clean air and water, pollination of plants, pest control, wastewater treatment and many ecosystem services. If no changes are made in the ways humans use resources on earth, there will continue to be a degradation of biodiversity until human lives can no longer be sustained. Humans affect biodiversity by their population numbers, use of land, and their lifestyles, causing damage to habitats for species.

Protists are a diverse group of eukaryotic organisms that are not animals, plants, or fungi. They are typically unicellular but can also be multicellular or colonial. Protists can be found in a variety of environments, including freshwater, marine, and soil, and can be free-living or symbiotic. They are an ancient group of organisms, and some of the earliest eukaryotes were likely protists.

The diversity of protists is immense, and they exhibit a wide range of characteristics and behaviors. Some protists are photosynthetic, using pigments like chlorophyll to capture sunlight and convert it into energy. Others are heterotrophic, consuming other organisms or organic matter. Some protists are capable of moving through their environment, using structures like flagella, cilia, or pseudopodia to propel themselves. Because of their diversity and importance in many ecosystems, protists are an important area of study in biology.

Answer: True

Explanation:

The artificial selection allows humans to exploit the genetic resources (alleles, genes) of the organisms during mating. This allows the transmission of valuable and desirable traits of both parents to the offspring. This improves the quality of milk, meat, and plant yield. Natural selection is a natural phenomenon human have no role in natural selection. In this the nature selects those individuals to survive in their environment which have better phenotypic traits over others. These traits allows the organism to survive and reproduce and the beneficial traits are passed on to the next generation. On contrary, the traits which are beneficial in one kind of environment can be harmful in other environment. For example, the bears have thick coat which allows them to survive in cold conditions but in extreme heat they may not survive.

Within a cell, DNA is housed in the nucleus (in eukaryotic cells) or in the nucleoid region (in prokaryotic cells).

DNA (Deoxyribonucleic acid) is a molecule that carries the genetic instructions used in the growth, development, functioning, and reproduction of all living organisms and many viruses. It is a long, double-stranded helical molecule composed of nucleotides, which are the basic building blocks of DNA.

Each nucleotide consists of a sugar molecule (deoxyribose), a phosphate group, and a nitrogenous base (adenine, guanine, cytosine, or thymine). The sequence of these bases determines the genetic code carried by the DNA molecule.

Thus, the DNA is housed in the nucleus in eukaryotic cells and in the nucleoid region in prokaryotic cells.

Answer:

Platelets help the blood clotting process (or coagulation) by gathering at the site of an injury, sticking to the lining of the injured blood vessel, and forming a platform on which blood coagulation can occur. This results in the formation of a fibrin clot, which covers the wound and prevents blood from leaking out.

Explanation:

Blood is composed of plasma, red blood cells, white blood cells, and platelets. Blood platelets play a role in coagulation (the clotting of blood to stop bleed from an open wound); white blood cells play an important role in the immune system; red blood cells transport oxygen and carbon dioxide.

Explanation:

Answer:

Using this technique, which they termed 'chemical amputation', the team induced lesions in planaria and investigated which genes were activated over the course of the regeneration process. The pharynx lacks neoblasts, but cells near the wound quickly start dividing and regenerate the amputated organ.

The steps which are involved when a planarian needs to generate new cells include the different stages of regeneration.

Regeneration in the planarians depends on the presence of stem cells called as neoblasts. These newly formed cells are distributed throughout the body and, when part of the worm has been amputated, these parts are activated to reform the tissues which have been removed.

Planarians also use this extraordinary regenerative ability to reproduce asexually. Through the process of transverse fissions, planarians which anchor their tails and also essentially pull themselves apart from each other, resulting in two fragments which include one head and one tail that will regenerate into two genetically identical worms.
