Using electricity sparingly in your home is beneficial for the
environment because it:
Select one:
1, increases the amount of greenhouse gases emitted into the atmosphere.
2, increases the rate of plant growth
3, increases levels of oxygen in the atmosphere.
4, reduces the amount of greenhouse gases emitted into the atmosphere.
Your requirement for electricity decreases as your home's energy efficiency rises, reducing your dependence on carbon-intensive power plants, and reducing the number of greenhouse gases emitted into the atmosphere, hence option 4 is correct.
How does electricity affect the greenhouse?This lowers the plant's demand from your house, which helps the environment by lowering carbon dioxide emissions and lessening atmospheric emissions of greenhouse gases.
This rise is the result of the air's carbon and oxygen being combined to create CO2 during the burning of coal or oil.
Therefore, greenhouse gas concentrations have increased due to human activity, hence option 4 is correct.

What does genetic modification do
Explanation:
Genetic modification is the process of altering the genetic makeup of an organism. This has been done indirectly for thousands of years by controlled, or selective, breeding of plants and animals. Modern biotechnology has made it easier and faster to target a specific gene for more-precise alteration of the organism through genetic engineering.
Hope Helps!Answer:
Please read below:
Explanation:
Genetic modification, also known as genetic engineering or genetic manipulation, is the process of altering the genetic makeup of living organisms. This is done by manipulating the DNA of a living organism to create a desired outcome. It involves the introduction of foreign DNA into the organism, often from another species, in order to produce a desired trait. It is used in a wide range of applications, ranging from agriculture to medicine.
In agriculture, genetic modification is used to create crops with heightened resistance to pests, diseases, and adverse environmental conditions. It can also be used to increase crop yields, improve nutritional value, and reduce the use of pesticides and fertilizers.
In medicine, genetic modification is used to create vaccines, improve the efficacy of existing drugs, and create treatments for genetic diseases. It is also used to create healthier food and beverages, as well as to create new materials with improved properties.
In biotechnology, genetic modification is used to create new products for use in research and industry. These products are often used to study diseases, develop new drugs, and create bioplastics and biofuels.
Genetic modification has been controversial since its inception, as it has been used to create genetically modified organisms (GMOs). These organisms, created through genetic modification, have the potential to disrupt natural ecosystems, as well as to cause health problems in humans. For this reason, the use of GMOs is heavily regulated in many countries, and the public is often divided on the issue.
Overall, genetic modification has the potential to revolutionize the way we produce food, create medicines, and develop new products. However, it is important to remember the ethical and environmental considerations that must be taken into account when using this technology.

A forest of pine trees is burned over a 10 mile area when lightning strikes a tree. In the spring, a few seedlings are beginning to sprout. ___________________________________ 2. A glacier has scraped all soil from a rocky area. As it slowly retreats, some of the rock is broken down by weathering. Some moss begins to grow. ___________________________________ 3. A small symbiotic organism secretes acid into the rock to anchor itself in place. ___________________________________
Answer:
1. A forest of pine trees is burned over a 10 mile area when lightning strikes a tree. In the spring, a few seedlings are beginning to sprout → secondary succession.
2. A glacier has scraped all soil from a rocky area. As it slowly retreats, some of the rock is broken down by weathering. Some moss begins to grow → primary succession.
3. A small symbiotic organism secretes acid into the rock to anchor itself in place → lichens - pioneer organisms.
Explanation:
The succession is the colonization of an open area and includes all the changes the area suffers since then. It is a sequence of events that involves the establishment of different species through time. A sequence of changes that occur in a community temporally and spatially. Local colonizations and extinctions occur while ecosystems evolve at a more complex level.
Ecological succession occurs in stages. The first stages are represented by communities of simple trophic levels and few species. With time, the communities go through different stages. They transform into more complex ecosystems that are much richer in diversity, showing more interaction among the different species that compose it. The final stage is known as the climax and represents a mature and stable system.
While the community is going through these changes, many species get extinct while many others get to emerge and survive. It occurs overlapping of different taxonomic groups that interact with each other competing or beneficiating other groups.
There are two types of succession, primary and secondary, depending on the magnitude of the alteration.
Primary succession refers to an open space with no living organisms, such as a bare rock exposed due to a retreating glacier, a volcanic activity, or an intense fire. If previous species were inhabiting this area, after the event, nothing is left.In those cases where there is an alteration or disturbance at a site that opens the area, it allows new species to grow. With time, new species arrive and manage to establish again. The order of the establishment depends on the strategies of each of the species to survive.
First, pioneer species arrive. These are the first inhabitants, mostly lichens or plants with the capability of surviving in such an environment. Only a few pioneers can establish in the open space. Pioneers modify the habitat, making it more suitable for the establishment of later species, converting rock into fertile soil. As conditions get better, new species arrive like grasses. Grasses and pioneers keep modifying the soil, making it better with time. New species arrive. Habitat modification keeps on going while new species establish. They produce shadows, alter the temperature, and humidity, fertilizing the soil, competing for resources. Competition becomes more frequent between species. The first species are eventually eliminated by competition, but new species keep appearing and competing for resources. This sequence continues until the commuting reaches a climax, becoming stable and lasting for hundreds of years until another disturbance occurs.
Secondary succession refers to an open space left after a perturbation that might have removed all or some of the vegetable forms of life that used to inhabits that area. But the soil remains good and fertile. It has spores and seeds that will emerge when the conditions are appropriate. The disturbance occurred but vegetable species have strategies to survive the event and grow once it´s over. Pine trees are adapted to fire, and some species need fire to germinate.Sentence Arrange - Put the steps of DNA replication in order by writing a number in the space before each statement. _____Two new molecules of DNA are created. _____DNA polymerase attach the free-floating nucleotides to the exposed nitrogen bases. _____ Helicase begins to break the hydrogen bonds between nitrogen bases. _____DNA is stabilize by the enzyme topoimerase. _____DNA ligase mends Okazaki fragments.
Answer:
1. Helicase begins to break the hydrogen bonds between nitrogen bases.
2. DNA is stabilized by the enzyme topoisomerase.
3.DNA polymerase attaches the free-floating nucleotides to the exposed nitrogen bases.
4. DNA ligase mends Okazaki fragments.
5. Two new molecules of DNA are created.
Explanation:
Replication is a cellular mechanism by which a DNA molecule is used as template to synthesize two identical DNA molecules, and then each daughter cell receives one DNA molecule during cell division. First, DNA unwinds at dynamic structures called replication forks: a helicase enzyme opens up the double helix of the DNA at the replication fork by breaking hydrogen bonds that hold complementary DNA strands together. Subsequently, a topoisomerase enzyme removes positive supercoils generated in front of the replication fork. In the next step, a DNA polymerase extends primers (i.e., short RNA sequences that serve as templates for the starting point of replication) by adding nucleotides to the 3' end of the growing strand. The replication continues in the 5' to 3' direction on the leading strand, while the strand of the DNA that runs 5' to 3' away from the replication fork (known as the lagging strand) must be synthesized in fragments called Okazaki fragments. Subsequently, a DNA ligase enzyme facilitates the joining of the Okazaki fragments by forming phosphodiester bonds between nucleotides, thereby resulting in a continuous lagging strand. Finally, replication ends when converging replication forks meet.

When two gametes combine during fertilization to produce children with distinct DNA combinations, this variety is amplified even more, hence a, b, d is the correct option.
What is genetic variation?Crossing over and independent segregation occurs during meiosis I, DNA is exchanged between homologous chromosomes during prophase I when cells cross over.
New allele combinations are produced as a result, chromosomes can arrange themselves in a variety of ways on the metaphase plate, and this process is known as independent segregation.
In metaphase I, this happens, independent segregation but not crossing across occurs during meiosis II.
Therefore meiosis creates variation in the organism which leads to changes during evolution, hence a,b,d is the correct option.

On Christmas Eve of 1998, the Ohio State Health Department announced that two elderly people had died during the previous six weeks, apparently after ingesting tainted meat. Ten additional non fatal cases were reported in the state during this period. The state epidemiologist was aware of a national outbreak of a disease with the symptoms seen in these cases. The symptoms included fever and muscle aches, and often diarrhea and nausea. Occasionally, the central nervous system was affected, resulting in confusion, stiff neck, headache, and convulsion. The nationwide outbreak affected approximately 50 people, with a particularly high infection rate in pregnant women and a significant number of deaths among fetuses. The Centers for Disease Control and Prevention (CDC) issued a list of people who were at particular risk for the disease. These included pregnant women, newborns, people with weakened immune systems, and the elderly. The CDC and the U.S. Department of Agriculture suspected pre packaged meats, such as hot dogs and cold cuts, as the source of the outbreak.
Required:
a. What is the most likely cause of the disease?
b. Why is this infection associated with processed meats, but not usually with hamburger or cuts of meat including pork, beef, or chicken?
Answer:See explanation
Explanation:
a. What is the most likely cause of the disease?
The most likely cause of the disease is Listeria monocytogenes.
b. Why is this infection associated with processed meats, but not usually with hamburger or cuts of meat including pork, beef, or chicken?
The Listeria monocytogenes gets into ones body through either food or drink. Under refrigeration, it can survive well and reproduce. In a situation whereby the meats that have been infected isn't properly heated well, then the bacterium will survive. On the other, hamburger or cuts of meat including pork, beef, or chicken are property heated well and therefore kills the bacteria.
