Answer:
1. artificial is done by humans, doesn't result in evolution or speciation and is a faster process
natural is random changes in the genotype of an organism that increase the change of the organism surviving and procreating thus passing on their genotype to the next generation
2. both can result in genotype and phenotype changes within a population
3. the environment and organisms are in constant relationship, as the environment changes the individual organisms within that environment that are best suited in a heritable way will survive and procreate more thus increasing the suitability of the population to the current environment
4. anytime a species is not able to replace it's numbers successfully, could be caused by environmental changes, predation pressures etc

What do you mean by energy?The "ability to do work, which is the ability to exert a force causing the displacement of an object" is the definition of energy. Despite this baffling definition, the meaning is quite straightforward: The only thing that makes things move is energy.
There are many different kinds of energy. These, for instance, are: electrical energy, sound energy, chemical energy, nuclear or atomic energy, mechanical energy, heat energy, gravitational energy, mechanical energy, and so on.
The body's capacity to perform work could be used to define energy. – The joule (J) is the SI unit for energy. or 1 kJ equals 1000 J. Energy forms: Potential energy, kinetic energy, heat energy, chemical energy, and light energy are the various forms.

Which statement about tornadoes is TRUE?
Select one:
Tornadoes occur randomly all over the planet, so it is impossible to determine where tornado risk is high.
Tornadoes do not have any warning signs, so it is impossible to determine when tornadoes are likely to occur.
Tornado conditions occur more often in certain regions, but they are so powerful that there is little residents can do to avoid damage from these events.

There are 1000 micrometres (um) in a millimetre (mm).
The length of the cell in Figure 1 is 1.5 micrometres (um).
Give the length of the cell in millimetres (mm).
(1 Point)
Answer: The length of the cell in millimetres is 0.0015.
Explanation:
Given conversion :
[tex]1000\mu m=1mm[/tex]
Thus [tex]1\mu m=\frac{1}{1000}mm=0.001mm[/tex]
Given : Length of the cell = 1.5 micrometers [tex](\mu m)[/tex]
To find: Length of the cell in milllimeters (mm)
Length of the cell in milllimeters (mm) = [tex]1.5\times 0.001mm=0.0015mm[/tex]
The length of the cell in millimetres is 0.0015.
Which sequence best explains the relationship between DNA and protein structure and function?
Answer:
DNA base triplets → amino acid sequence → protein folding pattern → protein shape and function
DNA sequence provides the code for the amino acid sequence. The amino acid sequence determines the protein structure, which affects the protein's function.
What is the relation between DNA and protein?The relation between DNA and protein can be described as follows:
DNA carries the genetic code: DNA is made up of a long chain of nucleotides, which are the building blocks of DNA. Each nucleotide consists of a sugar, a phosphate group, and a nitrogenous base. There are four types of nitrogenous bases in DNA: adenine, guanine, cytosine, and thymine. The sequence of these bases carries the genetic code that provides the instructions for the synthesis of proteins.
DNA is transcribed into RNA: The DNA code is transcribed into a complementary RNA (ribonucleic acid) molecule through a process called transcription. RNA is similar to DNA, but it is made up of a different sugar (ribose) and a different nitrogenous base (uracil).
RNA is translated into protein: The RNA molecule is then translated into the amino acid sequence of a protein through a process called translation. This involves the use of transfer RNA (tRNA) molecules, which carry specific amino acids and bind to the RNA molecule at specific codons (sequences of three nucleotides). The sequence of codons in the RNA molecule determines the sequence of amino acids in the protein.
Protein structure determines function: The amino acid sequence of a protein determines its three-dimensional structure, which in turn determines its function. Proteins can have a variety of functions in the body, including catalyzing chemical reactions, transporting molecules, providing structural support, and regulating cell function.

a laptop power changer has an output of 5.00 V ang has a resistance of 800 ohms. what is the current output of the charger?
Answer:
The correct answer is - 6.25 mAh.
Explanation:
According to the Ohms law of power, the current of a source can be found with the help of the formula
I = V ÷ R
where, I (amps) = V (volts) ÷ R (Ω)
By placing the value given:
I = 5.00/800
I = 6.25 mAh
The current output of the charger would be 6.25 mAh

once a cell becomes specialized, can it become any other type of cell? explain.
Answer:
a cell that has a specific job or function that carries out. -found in multicellular organisms (made of many cells) -once a specialized cell, it can not become any other cell.
Explanation:
Once a cell becomes specialized, it cannot become any other type of cell. This is because, this cell cannot form stem cells which have the ability to form different types of cells in the body.
Specialized cells are the cells which are designed to carry out a particular role in the body, such as that of red blood cells which are designed to carry oxygen gas in the blood. Nerve cells help in the contraction of muscles or the relaxation of muscles according to what the specific job we need them to do.
Cell differentiation is the process of specialization which lead to the formation of different organs such as brain, heart, and all other tissues from the single-cell zygote and the primitive, three-layered embryo.
Once a cell became specialized in the body, it was referred to as terminally differentiated cell. These cells cannot be turned back into a stem cell with the potential to become any type of cell in the body.

earth is more than 10 times as far from the sun as mercury is true or false
Answer:
Hope this helps, Brainliest?
Explanation:
With a radius of 1,516 miles (2,440 kilometers), Mercury is a little more than 1/3 the width of Earth. If Earth were the size of a nickel, Mercury would be about as big as a blueberry. From an average distance of 36 million miles (58 million kilometers), Mercury is 0.4 astronomical units away from the Sun.
With a radius of 1,516 miles (2,440 kilometers), Mercury is a little more than 1/3 the width of Earth. If Earth were the size of a nickel, Mercury would be about as big as a blueberry.
What is Mercury?At room temperature, metallic mercury is a lustrous, silver-white metal that was once known as quicksilver. Older thermometers, fluorescent lamps, and some electrical switches all use it.
When dropped, elemental mercury fragments into smaller droplets that may pass through tiny crevices or stick firmly to some objects. At room temperature, exposed elemental mercury can evaporate and turn into a poisonous vapor that is invisible and odorless.
Mercury that hasn't interacted with another substance is considered to be elemental mercury. In the presence of another chemical, mercury can combine to produce compounds like inorganic mercury.
Therefore, With a radius of 1,516 miles (2,440 kilometers), Mercury is a little more than 1/3 the width of Earth. If Earth were the size of a nickel, Mercury would be about as big as a blueberry.
