Answer:
The best estimate for Earth's age is based on radiometric dating of fragments from the Canyon Diablo iron meteorite. From the fragments, scientists calculated the relative abundances of elements that formed as radioactive uranium decayed over billions of years.The U.S. Congress adopted the Clean Air Act in 1970 and created the U.S. Environmental Protection Agency. Effective January 1, 1996, leaded gasoline was banned by the Clean Air Act for use in new vehicles other than aircraft, racing cars, farm equipment, and marine engines.Explanation:
In August 2004, Hurricane Charley made landfall in Florida. As a consequence, North Captiva Island was fragmented into two different island North Captiva has been one of the low buteds providing a home for the actor
Eastern Indigo snake. Which of the following describes the impact of Hurricane Charley on the Eastern Indigo snake?
1.Genetic diversity will decrease because of genetic drift caused by bottleneck effect
2.Mutations will decrease genetic diversity because the indigo snake became isolated
3. The snakes will learn to swim, become a new species, and emigrate to other parts of Florida.
4. The Easter Indigo will be forced to mate with other species of snakes and become a new species
Answer: the correct answer is actually
1.Genetic diversity will decrease because of genetic drift caused by bottleneck effect
Explanation: this is due to the bottleneck effect because the bottle neckeffect is when size or population decreases due to earthquakes human activity, etc;
1. Genetic diversity will decrease because of genetic drift caused by bottleneck effect
The following information should be considered:
The effect of Hurricane Charley on the Eastern Indigo snake should be because of the bottleneck impact since the bottle neck impact arise at the time when the size or population reduced.It is because of earthquakes, human activity.Learn more: https://brainly.com/question/2386757?referrer=searchResults
the order of nitrogen nases determines
Answer:
The order of these bases is what determines DNA's instructions, or genetic code.
Explanation:
can i get the crown
Answer:
The four types of nitrogen bases are adenine (A), thymine (T), guanine (G) and cytosine (C). The order of these bases is what determines DNA's instructions, or genetic code.

How is the rate of photosynthesis affected by wavelength?
what is codomaince? how does it affect the genotype?
Answer:
In complete dominance, only one allele in the genotype is seen in the phenotype. In codominance, both alleles in the genotype are seen in the phenotype. In incomplete dominance, a mixture of the alleles in the genotype is seen in the phenotype.

When a cel is placed in this type of solution, there will be equal amounts of water moving in and out of the cell at equal rates.
A. hypotonic
B. isotonic
C. supersonic
D. hypertonic
Answer:
B, Isotonic solution
Explanation:
In an isotonic solution, the flow of water in and out of the cell is happening at the same rate.
Answer:
A. hypotonic
Explanation:
In an isotonic solution, the flow of water in and out of the cell is happening at the same rate. Figure 9.7. 1: Red blood cells in hypertonic, isotonic, and hypotonic solutions.
Why does ice cream placed in a plastic cooler melt slower than ice cream placed in a metal pot?
A. because metal is a better insulator than plastic
B. because plastic is a better insulator than metal
C. because metal insulates against more heat
D. because plastic conducts more heat
Answer: B
Explanation:
Because Metal is a poor conductor of heat the inside of a plastic container is insulated and the ice cream will stay cooler longer

Why do soft sounds do less damage to your ears than loud sounds
Answer:
"The damage done by noise depends mainly on how loud it is and on the length of exposure. The frequency or pitch can also have some effect, since high-pitched sounds are more damaging than low-pitched sounds. Noise may tire out the inner ear, causing temporary hearing loss."

Besides for growth, what other reason would you want a new cell
to have the same exact DNA as the initial parent cell?
SELECT AN ANSWER
-You need to replace cells that are dead or
damaged.
-You want the new cell to have the
capability to live for an infinite amount of
time (avoid death).
-You want to avoid genetic mutations or
abnormalities.
-There is no other reason besides growth.
Answer:
You need to replace cells that are dead or
damaged.I think

Explanation:
specific defence systemwhite blood cells can do 3 things = they engulf the microbe, produce antitoxins, produce antibodies to neutralise microbe
> all cells carry a small protein on their surface called antigens
> every cell has a different shaped antigen
> also meaning if lets say a virus mutates its antigen will change shape
so there are 2 types of antibodies that help fight pathogens together
1) lymphocytes : recognise antigen and make a complementary antibody to fit the antigen this will neutralise the pathogen ( basically seals the whole pathogen with antibody meaning it cannot reproduce or produce toxins if bacteria) and ALSO THEY MAKE THE PATHOGEN BIND TOGETHER so that the phagocyte can kill more pathogen at once
2) phagocytes : do not produce antibodies. and they identify the antigen and ingest and destroy the pathogen 70% of white blood cells are phagocytes
fighting diseasesphagocytosis = process of phagocytes destroying pathogenantitoxins producedantibodies producedmacrophages = specialised cell involved in destruction of pathogennon specific defence systemskin

How are the various types of plants and fungi different from each other? What characteristics do plants and
fungi share?
Answer:
While both are eukaryotic and don't move, plants are autotrophic - making their own energy - and have cell walls made of cellulose, but fungi are heterotrophic - taking in food for energy - and have cell walls made of chitin.
Explanation:
does respiration increase or decrease atmospheric carbon?
Answer:
Carbon dioxide is added to the atmosphere naturally when organisms respire or decompose (decay), carbonate rocks are weathered, forest fires occur, and volcanoes erupt. Carbon dioxide is also added to the atmosphere through human activities, such as the burning of fossil fuels and forests and the production of cement.
Coal is a fossil fuel produced from plant material underground over very long geological periods of time. What are petroleum and natural gas originally formed from?
Which trait/s did the common ancestor
of Lizards and Chimpanzees NOT have?
how does a trait go from a gene to a protein?
Answer:
A gene codes for a particular protein that is involved in the expression of a trait. Characteristics determined by single genes are called Mendelian traits.
Explanation:
Answer:
The journey from gene to protein is complex and tightly controlled within each cell. It consists of two major steps: transcription and translation. Together, transcription and translation are known as gene expression.

what is the difference between light dependent and light indepenedent reactions
Answer:
The difference between light dependent and light independent reactions is light independent is energy from sunlight that is absorbed by Chlorophyll. Also light dependent is energy that is converted into stored chemical energy. In the independent reactions, the chemical energy basically harvests during the light dependent reactions, which drives the assembly of these sugar molecules from carbon dioxide.

What's the difference between monosomy and trisomy?
Answer:
Trisomies and monosomies are two types of chromosomal abnormalities. Specifically, a trisomy is when a person has three of a particular chromosome, instead of the usual two. A monosomy is when they just have one chromosome instead of the usual two.
For example: A trisomy is down syndrome
Explanation:
Answer:
trisomy is when a person has three of the particular chromosome rather than two. Monosomy is when someone has one chromosome rather than the usual two.
