Which of the following is a disadvantage of geothermal energy?
A. It is a nonrenewable resource.
B. Collecting it damages the environment.
C. It produces greenhouse gases.
D. It is available near the Earth's surface in relatively few areas.
Answer: D
Explanation: it is “location specific” and is found near the earths crust in few areas
The disadvantage of geothermal energy is that it is available near the Earth's surface in relatively few areas.
What is geothermal energy?'Geo' means Earth and 'thermal' means heat."It is a type of renewable energy (present in the form of heat) taken from the Earth's core."The energy that are inexhaustible or get renewed at very fast pace is called renewable energy.The heat that remains in the interior part of Earth since the time of its formation and radioactive decay of materials is used to generate electricity.It does not damages the environment.It does not emit greenhouse gases. That's why it does not cause climate change.It is available near the Earth's surface and it is location specific i.e., it is located in relatively few areas.Hence, the correct option is: D. It is available near the Earth's surface in relatively few areas.

2. Complete the following chart about the three main research projects
that led to the identification of DNA as the genetic material.
RESEARCHERS' NAMES
SUMMARY OF RESEARCH
SUMMARY OF CONCLUSIONS
Griffith
found a "transforming principle"
Avery
Hershey and Chase
identified the substance that phages inject
into bacteria
Answer:
Griffith's experiment, reported in 1928 by Frederick Griffith, was the first experiment suggesting that bacteria are capable of transferring genetic information through a process known as transformation. Griffith's findings were followed by research in the late 1930s and early 40s that isolated DNA as the material that communicated this genetic information.
Griffith's experiment discovering the "transforming principle" in pneumococcus bacteria.
Pneumonia was a serious cause of death in the wake of the post-WWI Spanish influenza pandemic, and Griffith was studying the possibility of creating a vaccine. Griffith used two strains of pneumococcus (Streptococcus pneumoniae) bacteria which infect mice – a type III-S (smooth) which was virulent, and a type II-R (rough) strain which was nonvirulent. The III-S strain synthesized a polysaccharide capsule that protected itself from the host's immune system, resulting in the death of the host, while the II-R strain did not have that protective capsule and was defeated by the host's immune system. A German bacteriologist, Fred Neufeld, had discovered the three pneumococcal types (Types I, II, and III) and discovered the quellung reaction to identify them in vitro. Until Griffith's experiment, bacteriologists believed that the types were fixed and unchangeable, from one generation to another.
In this experiment, bacteria from the III-S strain were killed by heat, and their remains were added to II-R strain bacteria. While neither alone harmed the mice, the combination was able to kill its host. Griffith was also able to isolate both live II-R and live III-S strains of pneumococcus from the blood of these dead mice. Griffith concluded that the type II-R had been "transformed" into the lethal III-S strain by a "transforming principle" that was somehow part of the dead III-S strain bacteria.
Completing the attached chart about the three main research projects ;
Griffith summary of research : Identified what R-strain bacteria took up from heat-killed S bacteria,Avery summary of research : Identified protein as not the transforming factorAvery summary of conclusion : Found a " transforming principle "Hershey and chase summary of conclusions : Found the " Infection and replication principle "All three researches were carried out to discover the genetic material ( DNA ) which is responsible for the transfer of genetic traits from parent cells to daughter cells.
Griffith research shows that bacterias can get there DNA ( genetic material ) through a process known as transformation and the experiment to prove this research was carried out by killing S bacterias through heat and then adding them to R-strain bacteria. Griffith observed and concluded that the Genetic materials of the S bacteria was taken up by the S -bacterias through a process known as " transforming principle "
During Avery research for the genetic material ( DNA ) Avery treated a mixture with DNA-destroying enzymes to see if the colonies of the mixture will transform but they failed to transform which proves that proteins are not the transforming factors and that DNA is the genetic material.
Hence we can conclude that Completing the attached chart about the three main research projects is as written above.

Black-footed ferrets are native to the Great Plains. They spend most of their
time underground in prairie dog burrows. Which factor would increase an
area's carrying capacity for black-footed ferrets?
A. Increased competition for space
B. Increased number of diseases
C. Increased number of predators
D. Increased availability of food
Answer:
D. Increased availability of food
Explanation:
Trust
The factor that would increase an area's carrying capacity for black-footed ferrets is the increased availability of food. The correct option is D.
What is carrying capacity?Carrying capacity is defined as the average population size of a species in a given habitat.
Environmental factors such as adequate food, shelter, water, and mates limit the species population size. If these requirements are not met, the population will decline until the resources recover.
If there is more food available in an area, more black-footed ferrets can survive and reproduce, increasing the species' carrying capacity.
Increased competition for space, more diseases, and more predators would all reduce the carrying capacity of black-footed ferrets by reducing the number of individuals that could survive and reproduce in the area.
Thus, the correct option is D.

Which takes place inside the chloroplast?
A. dark reaction only
B. light reaction and cellular respiration
C. light and dark reactions
D. light reaction only
Answer:
dark and light reaction both is the right answerrrerreer
Answer:
C
Explanation:
The light reaction takes place in the thylakoid discs. Inside, water (H20) is oxidized, and oxygen (O2) is released. The electrons freed up from water are transfered to ATP and NADPH. The dark reaction occurs outside of the thylakoids. In this reaction, the energy from ATP and NADPH are used to fix carbon dioxide (CO2). The products of this reaction are sugar molecules and other organic molecules necessary for cell function and metabolism.
*Note the dark reaction takes place in the stroma (aqueous fluid surrounding the stacks of thylakoids) and the cytoplasm.
what important role does the magnetic field play for our planet ?
Earth's magnetic field serves to deflect most of the solar wind, whose charged particles would otherwise strip away the ozone layer that protects the Earth from harmful ultraviolet radiation. One stripping mechanism is for gas to be caught in bubbles of magnetic field, which are ripped off by solar winds.
Calculate: Punnett squares can be used to predict probable outcomes of genetic crosses. To calculate probability, divide the number of one kind of possible outcome by the total number of all possible outcomes. For example, if you toss a coin, the chance it will land on heads is equal to 1 ÷ 2. This probability can be expressed as ½, 0.5, or 50%.
