D. improve energy efficiency and reduce energy waste
Answer: D
Explanation: just took the quiz
The best solution that meets the energy demands while protecting the environment is to improve energy efficiency and reduce energy waste. Thus, the correct option for this question is D.
What is the Environment?The environment may be defined as a sum total of all forms of living and non-living elements and their consequences that significantly influence human life. It includes biotic and abiotic factors. The term environment is first given by Carlyle.
The protection of the environment requires a lot of actions by humans and the cooperation of other living organisms as well. All these actions impact the protection of the environment and improve energy efficiency along with the reduction in energy waste.
Therefore, improving energy efficiency and reducing energy waste is the best solution that meets energy demands while protecting the environment. Thus, the correct option for this question is D.

dichotomous key of a cockroach
Answer:
Identification of cockroaches is limited here to adults. A major source of confusion is the recognition of adults from nymphs.There are subjective differences, as well as morphological differences. Immature cockroaches are known as nymphs. Nymphs closely resemble adults except nymphs are generally smaller and lack wings and genital openings or copulatory appendages at the tip of their abdomen. Many species, however, have wingless adult females. Nymphs of these may be recognized by their shorter, relatively broad cerci and lack of external genitalia. Male cockroaches possess styli in addition to paired cerci. Styli arise from the subgenital plate and are generally conspicuous, but may also be reduced in some species. Styli are absent in adult females and nymphs

Why is the timing of a mutation in relation to fertilization important in whether it can be passed onto offspring?
Answer:
Since all cells in our body contain DNA, there are lots of places for mutation to occur; however, some mutations cannot be passed on to the offspring and do not matter for evolution.

Benny uses a compass to navigate his way through the woods when he
is carnping. The needle on the compass reacts to Earth's magnetic field
by always pointing north. Which part of Earth is responsible for creating
its magnetic field?
A. Cilist
B. inner core
C. mantle
D. outer core
Answer
Outer Core
Because of the weight of the melting moving metal creates energy
Our planet is shielded from cosmic radiation and charged particles from our Sun by the magnetic field, which is created by the motion of molten iron in the Earth's core. It also offers the framework for compass navigation. Thus, option D is correct.
What role of outer core of earth in magnetic field?Radiative heating and chemical differentiation have caused the Earth's outer core to be in a state of turbulent convection.
The convective kinetic energy is transformed into electrical and magnetic energy through a mechanism that is somewhat similar to a naturally occurring electrical generator.
The magnetic field is not produced by the earth's core, since metals lose their magnetic characteristics at high temperatures.
Therefore, Because of the weight of the melting, moving metal creates energy.

How are mid-ocean ridges formed at divergent tectonic plates?
The plates are moving in a zigzag formation, creating shallow earthquakes which forms a mid-ocean ridge.
Mid-ocean ridges are not resulting features of ocean-to-ocean divergent boundary zones.
The plates are moving towards each other, which causes the crust to buckle and push upwards or sideways which forms a mid-ocean ridge.
The stretching lithosphere is pushed up as the plates move apart.
Answer:
The stretching lithosphere is pushed up as the plates move apart.
Explanation:
Mid-ocean ridges are basically underwater mountains that are created with the help of lava convection (which causes the rising of plates) and the diverging (the pulling away) of tectonic plates. This is also how ocean floor spreading happens.
I know that mountains are formed by the converging of tectonic plates, but ocean ridges are NOT created like this.

Answer:
gaining modification in their Gene's which helped them to resist that particular pesticide
These surviving insects contributed to an increase in their population by passing genes for DDT resistance to the next generation.
What is a resistance gene?In order to survive, bacteria can create mechanisms known as resistance against antibiotics and antifungals. The germ's resistance mechanisms are determined by the specific proteins that DNA instructs the germ to produce. Many different forms of resistance genes can be found in bacteria and fungi.
Once a bacteria have acquired a resistance gene and incorporated it into its DNA, the bacterium can dominate other bacteria and convey the resistance gene to all of its offspring. Bacteria reproduce quickly, which amplifies resistance.
Hence, These surviving insects contributed to an increase in their population by passing genes for DDT resistance to the next generation.

While a high standard deviation suggests that the values are dispersed throughout a larger range, a low standard deviation suggests that the values tend to be near to the established mean.
An average is one number chosen to represent a group of numbers; it is often the sum of the numbers divided by the number of numbers in the group. The average of the integers 2, 3, 4, 7, and 9 is, for instance, 5.

Oil extraction is the process of recovering crude oil from underground reservoirs, in recent years, the process of oil extraction has changed, with new technologies and techniques allowing for more efficient and cost-effective oil production.
What is oil extraction?
The process of oil extraction involves drilling wells into the earth and then using various techniques to bring the oil to the surface, and the first step in oil extraction is to identify a suitable location for drilling, which is typically done using geologic surveys and other exploration techniques to locate areas with the potential for oil reserves, next step is to complete the well by installing a casing that helps to prevent the well from collapsing. Technologies such as "hydraulic fracturing," which involves injecting water and sand and assisting in the release of trapped oil and gas, have recently gained popularity.

what are the two main types of chemical bonds?
Answer:
Chemical bonds include covalent, polar covalent, and ionic bonds. Atoms with relatively similar electronegativities share electrons between them and are connected by covalent bonds. Atoms with large differences in electronegativity transfer electrons to form ions. The ions then are attracted to each other.
Two of the strongest forms of chemical bond are the ionic and the covalent bonds. Chemical bonds form between two atoms, each with its own electron environment.
