they can be formed into fossil fuels by breaking down.
Explanation:
Fossil fuels are formed when organic matter that has been buried deep within the earth are subject to heat and pressure over millions of years. ...

why is not recommended to use antibiotics often
Answer: It may cause the bacteria to become resistant to them and one they are resistant then the antibiotics are ineffective against the bacteria. It is then more dangerous since new antibiotics will need time.
Explanation:
Explanation:
If you take antibiotics for the wrong reason(s) or if you take them too often it can change bacteria so much, that antibiotics have a reduced effectiveness against them, or stop working against them all together.
The so called "bacterial resistance" or "antibiotic resistance" is a real thread to humans. Some bacteria have turned out to be resistant to even the most powerful antibiotics available. Antibiotic resistance is a growing problem.
Suppose you get infected with such resident bacteria, it means there is no longer an effective treatment by using antibiotics.
*EXTRA*
If left "un treated", the bacteria can grow, more or less, with unlimited exponential growth. In such scenarios, any "simple" bacterial infection, could turn out to be fatal.
Often the biggest problem is the lack of time to find out exactly what type of bacteria is making the patient ill. Because there are so many different bacteria, it is impossible to tell what is the right one without deduction and, that takes time (to grow visible cultures in the laboratory). Sometimes a patient might be already critically ill, in such cases, the doctor would want to start the treatment immediately, which could mean they HAVE TO start admitting a broad-spectrum antibiotic, to hopefully battle that group of different bacteria, which hopefully included the one that is making the patient ill. But if that specific bacteria turns out to be resestant, then that poses a very serious problem. Possible a fatal one, since the time is up, and the bacteria keep growing in numbers, roughly doubling in numbers every hour...

Explanation:
A plant has two alleles for color. The red allele is recessive, and is represented by q. The purple allele is dominant, and is represented by p. If 59 of 100 organisms are red, what is q? P^2 2pq q^2=1
Answer:
q is 0.7681
Explanation:
The red allele is recessive, and is represented by q.
If 59 of 100 organisms are red meaning the frequency of the recessive genotype of red is 59/100 = 0.59 represented by q².
Thus q would be to find the square root of q². Where q is the frequency of the recessive allele in the population
Thus, q = √q² where q² = 0.59
q = √0.59
q = 0.7681

Which three are formed due to compression? syncline, normal fault, and strike-slip fault anticline, syncline, and reverse fault normal fault, anticline, and strike-slip fault reverse fault, strike-slip fault, and syncline
Answer:
The correct option is B.
B) Anticline, Syncline and Reverse Fault
Explanation:
Anticline and Syncline are the terms which are used to describe the folds that occur on a rock. These are up and down folds that occur together and are caused by compressional stress.
Reverse fault is caused by compressional stress which is caused by rocks which are pushing into each other. It is considered as the opposite of Normal fault. In this, the hanging wall and footwall are pushed together, and the hanging wall moves upwards along the fault relative to footwall.

Which statement gives one reason that watershed protection programs are needed in Virginia
Ecosystems need to be controlled
Foods must be prevented
Dams can be damaged and may require repair
Wildlife can ruin water source when building habitats
Answer:
Dams can be damaged and may require repair
Explanation:
This is imperative to provide needed supports and maintenance for the aging dams,with capacity of up to 11,000. This dams were created as far back as 1948.Therefore the programme was geared towards effective re-habitation for maximum efficiency.
This repair programmes was termed Dam Rehabilitation Programme.And the secretary of Agriculture was given the authority to ensure effective execution of the programme.
In the state of Virginia,a total of 150 dams were part of the government landscape through the rehabilitation programme, and 11 of these have been well studied. .Todd Lake,Robinson Hallow, Lake Barton are some of these examples.

In 1953, Stanley Miller and Harold Urey built a model of Earth's early
atmosphere by mixing gases that were thought to have been there. They
exposed the gases to an electric current to simulate lightning. The liquid that
condensed during the experiment contained amino acids.
What was the significance of their results?
O A. Miller and Urey proved the theory of spontaneous generation.
B. Miller and Urey proved that all life evolved from a single common
ancestor.
C. Miller and Urey proved that lightning was necessary for life to form
on Earth
O
D. Miller and Urey proved that biological molecules could have
formed in a similar way.
The essence of the experiment was that it showed that biological molecules could have formed in a similar way.
What was the experiment of Miller and Urey?The experiments of Miller and Urey were the first step in trying to prove the idea tat life originated from simple biological molecules.
Though the life forms did not form from the gases that were used, but the biological molecules did form. Thus, the essence of the experiment was that it showed that biological molecules could have formed in a similar way.

What are the three types of muscle fibers? A) smooth, intermediate- twitch, cardiac B) slow- twitch, intermediate- twitch, fast-twitch C) slow-twitch, fast-twitch, involuntary
Answer:
B) slow- twitch, intermediate- twitch, fast-twitch
Explanation:
The three types of muscle fibers are:
Slow-twitch: they are also called Red Fibers because of their color or type I. These type of fibers are resistant to fatigue, that means that they can contract for long periods, but its contraction is not very strong. Muscles that maintain our posture, such as our back muscles, have a predominancy of these types of fibers.Fast-twitch fibers: they are also called type II, or White Fibers because of their color due to the low supply of blood. They are fibers that contract very fast and are not resistant to fatigue. These types of fibers can generate higher amounts of force in a short period, but their contraction is for a short period. They are present in our eye's muscles.Intermediate twitch fibers: they characteristics are between the two types of fibers mentioned above. That is to say, that they do not contract as fast as fast-twitch fibers do but not as slow as slow fibers either, also, they fatigue quickly but nos as quicky as fast-twitch fibers or as slow as slow-twitch. They are in the majority of our muscles.
