Answer:
Humans are one of the important contributor for CO2 (Carbon Dioxide) Production. In our body, carbon dioxide is formed intracellularly as a byproduct of metabolism. Carbon Dioxide is transported in the bloodstream to the lungs where it is ultimately removed from the body through exhalation. This process is called Respiration generally Cellular Respiration.
And in Photosynthesis, the exhaled CO2 from human body ( or any other living organisms) are being used as the reactant (with the H2O) then produces Glucose (energy source of plants) and Oxygen (living organisms need to survive). This process takes place in chloroplasts, which contain the chlorophyll.
To sum up, carbon cycle is the process in which carbon travels from the atmosphere into organisms and the Earth and then back into the atmosphere. Plants take carbon dioxide from the air and use it to make food. Animals then eat the food and carbon is stored in their bodies or released as CO2 through respiration.
Therefore, without living organisms there are no carbon dioxide, oxygen and other gases will be produce same as without non-living organisms like gases, the sun, water and etc. human race and other organisms can't survive. And there will be no ecosystem.
Answer: down there
Explanation: Feral swine are not native to the Americas. They were first brought to the United States in the 1500s by early explorers and settlers as a source of food. Free-range livestock management practices and escapes from enclosures led to the first establishment of feral swine populations within the United States. In the 1900s, the Eurasian or Russian wild boar was introduced into parts of the United States for the purpose of sport hunting. Today, feral swine are a combination of escaped domestic pigs, Eurasian wild boars, and hybrids of the two.
Feral swine have been reported in at least 35 states. Their population is estimated at over 6 million and is rapidly expanding. Range expansion over the last few decades is due to a variety of factors including their adaptability to a variety of climates and conditions, translocation by humans, and a lack of natural predators.
1. two cell divisions = meiosis.
In meiosis one 2n (diploid) cell divides into 4 n (haploid) genetically diverse cells. There are two divisions. 1 -> 2 -> 4. In mitosis one diploid cell divides into two identical diploid cells, so there is only one division.
2. DNA replication = both!
In the life cycle of any cell (cell cycle), during the synthesis period of interphase DNA replication occurs. Cells have unduplicated chromosomes in G1 (before replication/synthesis) and duplicated chromosomes in G2 (after replication/synthesis). In mitosis, they are replicated so that the chromosomes can be split into two cells (duplicated chromosomes are ripped in half, so the daughter cells have unduplicated chromosomes after cell division). In meiosis, they are also replicated for the same reason, but the homologous pairs are additionally split up so that the four daughter cells are all haploid.
3. chromosomes pair up = meiosis
In meiosis the additional "sorting" of genetic information happens because 1 diploid cell is going to make 4 haploid cells. The homologous pairs find their mate and during metaphase I the homologous chromosomes line up in pairs and one of each pair is divided into the first division of cells. This "pairing up" happens in prophase I of meiosis and is called "synapsis"!
4. spindle fibers form = both!
In both mitosis and meiosis the spindle fibers come out from the centrosomes and attach to the chromosome halves in mitosis and meiosis II and attach to each chromosome of the homologous pairs in meiosis I. The basic process of division is the same in both.
5. one cell division = mitosis
See my answer for #1.
6. cytokinesis = both!
Cytokinesis is the splitting of the cytoplasm and the essence of "cell division," which happens in both mitosis and meiosis. It just happens twice in meiosis.
7. four daughter cells = meiosis
In meiosis one diploid (2n) somatic cell divides to form 4 genetically diverse haploid (n) gamete cells. Remember this!
The correct answer is option (A) The snake population will decrease rapidly and the grass population will increase rapidly.
A food chain can be defined as a linear sequence of organisms through which the nutrients and energy flow as one organisms feeds on the other. Each level of the food chain is called the trophic level. They show organisms starting from the producers and end with consumers or sometimes with detrivores or decomposers. The producers which use solar energy and prepare their food occupy the first trophic level, followed by the primary, secondary, tertiary, quaternary consumers occupying the next trophic level.
In the terrestrial food chain given above, grass → rabbit → snake → Hawk, the decrease in the any population will effect the other organism at a different trophic level of the food chain. A sudden decrease in the population of rabbits due to trapping will rapidly decrease the snake population due to scarcity of food and the grass population will increase rapidly due to the lack of the consumers which are the rabbits.
